DividendMapper does not provide personalised retirement-planning or tax-planning advice. The 2026/27 dividend-tax band rates (8.75% basic-rate / 33.75% higher-rate / 39.35% additional-rate), the £500 dividend allowance, the £3,000 annual exempt amount, and the Section 1K TCGA 1992 spouse-couple CGT exemption reflect current UK tax law - readers should verify current rules before acting on any framework output. The 2026/27 tax-year rules reflect current rules. Bed-and-spouse transfers require careful annual review of the marginal-rate split, the dividend-allowance usage, and the cross-spouse rebalancing cadence - these are beyond the scope of this educational article. UK tax law changes over time. Readers should consult a regulated financial adviser for personalised advice.

1. What bed-and-spouse CGT-exempt transfers actually are for UK dividend investors

Bed-and-spouse is the transfer of GIA (General Investment Account) holdings between spouses (or civil partners) without triggering a CGT disposal, under Section 1K of the Taxation of Chargeable Gains Act 1992. The receiving spouse takes the donor's cost basis - there is no step-up at transfer. After the transfer, future disposals are taxed at the receiving spouse's own marginal rate.

For UK dividend investors, this is the cleanest mechanism for the cross-spouse dividend-allocation framework. A couple with an uneven marginal-rate split (one spouse at higher-rate or additional-rate, the other at basic-rate or below the dividend allowance) can shift dividend-paying GIA holdings from the higher-rate spouse to the lower-rate spouse to reduce household dividend tax. The savings range from £560/year per £10,000 shifted (additional-rate to higher-rate) to £2,500/year per £10,000 shifted (higher-rate to basic-rate).

Section 1K TCGA 1992 statutory basis. The spouse-couple CGT exemption applies to transfers between spouses or civil partners living together in the same tax year. Transfers between unmarried partners do not qualify - even if the partners live together. Transfers between former spouses under a court-ordered settlement also qualify, but with a different rule (the receiving spouse takes the market-value-at-transfer cost basis, which is a step-up from the donor's basis; not the cost-basis carryover rule that applies during marriage).

No disposal at transfer. A bed-and-spouse transfer is not treated as a CGT disposal. The donor's unrealised gain migrates to the receiving spouse without being crystallised. The donor's acquisition date is preserved. The donor's incidental costs (broker fees, stamp duty) are preserved.

The cost-basis carryover rule. The receiving spouse inherits the donor's cost basis. A shareholding acquired for £5,000 that is now worth £10,000 (unrealised gain £5,000) transferred to the lower-rate spouse does not create a CGT event. The lower-rate spouse now owns the £5,000 unrealised gain. When the receiving spouse eventually sells, the gain is calculated as (sale price - donor's cost basis) and taxed at the receiving spouse's marginal rate at the time of disposal.

No step-up at transfer. Crucially, bed-and-spouse transfers at fair market value do not trigger a step-up. This is unlike inheritance, where the recipient takes the probate-value cost basis. With bed-and-spouse, the future CGT bill migrates with the holding. Couples should not view bed-and-spouse as a "tax-free reset" - it is a tax-deferred reallocation of dividend income that preserves the future CGT liability at the receiving spouse's rate.

The partial-disposal rule. Bed-and-spouse can be used to transfer part of a holding (for example, 200 of 1,000 shares in a particular FTSE 100 dividend payer). The receiving spouse's cost basis on the partial transfer is (donor's average cost per share × number of shares transferred). The donor retains the remainder at the original cost basis.

Most UK dividend-investment content covers the per-spouse dividend-allowance usage (dividend-tax-calculator-uk-2026-27, item 123, audited-and-passed) or the per-retiree drawdown framework (dividend-retirement-drawdown-order-uk-dividend-investors, item 129, audited-and-passed), but does not walk through the bed-and-spouse CGT-exempt transfer mechanic comprehensively. The couple-coordinated-dividend-drawdown-uk-investors article (item 155, drafted 2026-07-14) treats bed-and-spouse as a single FAQ entry under the cross-spouse dividend-allocation framework but does not bridge to a standalone treatment of the Section 1K TCGA 1992 mechanic, the cost-basis carryover rule, the rebalancing tax interaction, the timing-of-transfer-with-ex-dividend-date interaction, or the worked UK investor arithmetic on the household tax saving per £10,000 transferred.

2. The cross-spouse dividend-allocation framework

The cross-spouse dividend-allocation framework is the direct application of bed-and-spouse to dividend-paying GIA holdings. The framework determines which spouse should hold the dividend-paying GIA assets to minimise the household dividend-tax bill.

The basic-rate vs higher-rate band difference. 8.75% (basic-rate) vs 33.75% (higher-rate) = 25 percentage points difference. For every £10,000 of dividend income shifted from the higher-rate spouse to the basic-rate spouse, the household saves £2,500/year (25 percentage points × £10,000). This is the largest single saving available from the cross-spouse dividend allocation.

The additional-rate vs higher-rate band difference. 39.35% (additional-rate) vs 33.75% (higher-rate) = 5.6 percentage points difference. For every £10,000 of dividend income shifted from the additional-rate spouse to the higher-rate spouse, the household saves £560/year.

The basic-rate vs dividend-allowance-only band difference. 8.75% (basic-rate) vs 0% (within the £500 dividend allowance) = 8.75 percentage points difference. For every £10,000 of dividend income shifted from a basic-rate spouse to a dividend-allowance-only spouse (whose £500 is unused), the household saves £875/year. If the recipient is in the basic-rate band but has unused dividend allowance, the absorption is more nuanced (see below).

The dividend-allowance absorption rule. Each spouse uses their own £500 dividend allowance first. Shifting dividend income to a spouse who has already exhausted their £500 dividend allowance gives the full band-rate savings on the entire shifted amount. Shifting dividend income to a spouse whose £500 is unused gives the £500 absorption first (£43.75/year saving on the first £500 shifted, i.e. 8.75% × £500), then the band-rate saving on the rest.

For Sarah-and-James in worked example 1 below: shift £20,000 from James (higher-rate) to Sarah (basic-rate). Sarah's £500 dividend allowance absorbs the first £500 of the new dividend at 0% (saving £43.75 if the allowance is unused) and then the remaining £19,500 saves 25 percentage points (saving £4,875). Total saving: £4,918.75. The brief's headline figure of £4,875 is the post-allowance saving on the £19,500 portion; the full accounting includes the £43.75 allowance saving.

The ISA dividend-allocation alternative. ISA dividends are tax-free regardless of which spouse holds the ISA. There is no cross-spouse ISA dividend-allocation benefit - the dividend tax is zero in both cases. Couples with ISA headroom available should prioritise ISA contribution before considering the cross-spouse GIA dividend allocation. This is the framework covered in the two-spouse-isa-contribution-ordering-uk-dividend-investors article (item 133, drafted 2026-07-07).

The SIPP dividend-allocation alternative. SIPP dividends compound gross inside the wrapper and are not currently taxed. The cross-spouse allocation does not affect the current-year dividend tax, but does affect the future drawdown-side tax treatment: allocating SIPP growth assets to the lower-marginal-rate spouse means the eventual SIPP drawdown will be taxed at that spouse's lower marginal rate. The cross-spouse SIPP drawdown sequencing is covered in the couple-coordinated-dividend-drawdown-uk-investors article (item 155, drafted 2026-07-14).

Why the cross-spouse allocation favours GIA over ISA/SIPP. The cross-spouse allocation has direct, immediate household dividend-tax benefit only for GIA holdings. ISA and SIPP holdings gain the benefit indirectly (via future drawdown for SIPP, no benefit for ISA). Couples with GIA dividend income above ~£5,000/year should consider the cross-spouse allocation as a primary lever after maximising ISA contributions.

3. The cost-basis carryover and future CGT mechanics

The cost-basis carryover rule and the future CGT mechanics are the second pillar of the bed-and-spouse framework. Couples should understand both the immediate dividend-tax benefit and the future CGT consequence before executing a bed-and-spouse transfer.

No CGT step-up at transfer. The receiving spouse inherits the donor's unrealised gain. A £10,000 holding at £5,000 cost basis (£5,000 unrealised gain) transferred to the lower-rate spouse does not crystallise a disposal. The receiving spouse now owns the £5,000 unrealised gain, but at their marginal rate rather than the donor's marginal rate.

Future CGT calculation on disposal. When the receiving spouse eventually sells, the gain is calculated as (sale price - donor's cost basis). The CGT rate applied is the receiving spouse's marginal rate at the time of disposal. UK CGT rates for the 2026/27 tax year are 18% (basic-rate residential property), 24% (basic-rate non-residential property, which is the standard rate for shares), and 24% (higher-rate). For shares held outside an ISA, the higher-rate CGT rate is 24% regardless of the marginal-rate band, so the bed-and-spouse CGT benefit depends on whether the receiving spouse is basic-rate (24% on the gain) or higher-rate (24% on the gain). For most dividend-investing couples, the receiving spouse's CGT rate is 24% - the same as the donor's - so the CGT component is roughly neutral.

Annual exempt amount (AEA) treatment on disposal. Each spouse has their own £3,000 AEA (2024/25 onwards; previously £12,300). The donor's AEA usage does NOT transfer. The receiving spouse uses their own £3,000 AEA against the eventual gain. Bed-and-spouse transfers do not affect either spouse's AEA status in the year of transfer. Cross-spouse AEA stacking: the household has 2 × £3,000 = £6,000 of AEA per tax year, and each spouse's AEA is independent.

Example of the future CGT interaction. Donor (higher-rate at the time of transfer) holds shares with a £20,000 unrealised gain. Donor's eventual CGT bill if sold today at higher-rate: £20,000 - £3,000 AEA = £17,000 × 24% = £4,080. Receives via bed-and-spouse (basic-rate spouse). Receives eventually sells at basic-rate at £20,000 profit: £20,000 - £3,000 AEA = £17,000 × 24% = £4,080. Same. But if the receiving spouse remains basic-rate for life and the donor would have been higher-rate at eventual disposal, the CGT bill is identical.

Bed-and-spouse transfers and CGT loss-harvesting. If the donor has an unrealised loss on a holding, transferring it to the higher-rate spouse via bed-and-spouse preserves the loss for the higher-rate spouse to harvest against future gains. The higher CGT rate makes the loss more valuable when offset against gains. Bed-and-spouse loss transfers are an underused CGT-planning tool.

Bed-and-ISA contrast. The bed-and-ISA mechanic (covered in the bed-and-isa-uk-dividend-investors article, item 137, drafted 2026-07-09) sells shares at a gain and rebuys them within an ISA within 30 days, crystallising the gain but moving future dividend and growth into the ISA wrapper. Bed-and-spouse is fundamentally different: no disposal at transfer, no 30-day anti-avoidance rule, no crystallised gain, just a reallocation of future dividend-tax liability.

Why the cost-basis carryover matters. Couples without the cost-basis carryover rule would have a stronger incentive to transfer only loss-making or low-gain holdings, leaving the high-gain holdings with the donor. With cost-basis carryover, all holdings can be transferred without prejudicing the future CGT position. This makes the bed-and-spouse framework broadly applicable across the portfolio, not just to selected holdings.

4. The 2026/27 tax-year-specific worked examples

Four worked UK investor scenarios to anchor the bed-and-spouse CGT-exempt transfer framework for the 2026/27 tax year. All arithmetic is composite-only, all names are illustrative, all marginal-rate bands reflect the current 2026/27 rates.

Worked example 1 - Sarah and James the £800,000-portfolio couple (basic-rate + higher-rate)

Sarah age 65 is a basic-rate retiree with a £300,000 portfolio (mostly ISA and GIA dividend-payers). Her adjusted income is £18,000 (state pension + small SIPP drawdown). James age 68 is a higher-rate retiree with a £500,000 portfolio (mostly GIA dividend-payers plus a £200,000 SIPP). James's adjusted income is £55,000 (SIPP drawdown + GIA dividend income). Combined household portfolio: £800,000. Combined household dividend income: ~£32,000/year (4% yield across GIA holdings).

Current allocation. All GIA dividend-paying holdings sit in James's name. James's dividend bill: £500 dividend allowance + £32,000 above the allowance × 33.75% (higher-rate) = £500 + £10,800 = £10,800/year approximately. Sarah's dividend bill: £0 (her ISA covers her holdings).

Bed-and-spouse shift. Shift £20,000 of dividend-paying GIA holdings from James to Sarah. After Sarah's £500 dividend-allowance absorption, the remaining £19,500 saves 25 percentage points. Total household saving on the dividend: £4,918.75/year. Net headline saving (post-allowance absorption): £4,875/year.

Future CGT impact. The £20,000 of holdings carries some unrealised gain from James's original purchase. Sarah takes James's cost basis. If Sarah sells at basic-rate in 5 years and the holdings have grown to £25,000, the gain is (sale - James's cost basis), calculated at basic-rate 24%. There is no CGT advantage or disadvantage from the bed-and-spouse transfer itself; the CGT component is neutral when both spouses would be at higher-rate at the time of sale, and Sarah's basic-rate at sale gives the same 24% rate as James's higher-rate at the time of the original CGT calculation. The transfer is principally a dividend-tax reallocation.

Documentation. Record the transfer date, the holding (number of shares × security identifier), James's original acquisition date, James's original cost basis (price per share × number of shares), and the transfer value (market value at transfer date) for Sarah's future CGT records.

Worked example 2 - Margaret and Tom the £1,500,000-portfolio couple (additional-rate + higher-rate)

Margaret age 70 is an additional-rate retiree with a £800,000 portfolio (mostly GIA dividend-payers plus a £300,000 SIPP). Margaret's adjusted income is £150,000 (SIPP drawdown + large GIA dividend income). Tom age 73 is a higher-rate retiree with a £700,000 portfolio (mostly ISA and GIA dividend-payers plus a £200,000 SIPP). Tom's adjusted income is £60,000 (SIPP drawdown + GIA dividend income). Combined household portfolio: £1,500,000. Combined household dividend income: ~£60,000/year (4% yield across GIA holdings).

Current allocation. GIA dividend-paying holdings are split roughly evenly between Margaret and Tom (despite Margaret being additional-rate and Tom being higher-rate). Margaret's dividend bill on her £30,000 GIA dividend: £500 dividend allowance + £29,500 × 39.35% (additional-rate) = £500 + £11,608.25 = £12,108.25/year. Tom's dividend bill on his £30,000 GIA dividend: £500 dividend allowance + £29,500 × 33.75% (higher-rate) = £500 + £9,956.25 = £10,456.25/year. Combined household dividend bill: £22,564.50/year.

Bed-and-spouse shift. Shift £15,000 of dividend-paying GIA holdings from Margaret (additional-rate) to Tom (higher-rate). The shift is from higher-rate donor to lower-rate (in this couple's terms) recipient, but here Tom is the lower-rate recipient than Margaret. After Tom's £500 dividend-allowance absorption, the remaining £14,500 saves 5.6 percentage points. Total household saving: £812/year.

Why the saving is modest. The additional-rate to higher-rate band gap is only 5.6 percentage points, compared to the 25 percentage-point gap from higher-rate to basic-rate. For additional-rate couples, the bed-and-spouse saving is meaningful but smaller per-£10,000 than for higher-rate-to-basic-rate couples. Additional-rate couples should consider additional levers (lower SIPP drawdown in the year of the transfer, marriage-allowance-style transfers if any spouse is non-taxpayer) before relying primarily on bed-and-spouse.

Documentation. Record the transfer with full CGT trail. Margaret's original cost basis carries over to Tom. If Tom sells at higher-rate in 5 years and the gain is £10,000, the CGT bill is £10,000 - £3,000 AEA × 24% = £1,680. Same as if Margaret had sold at additional-rate: CGT on shares is 24% for both marginal-rate bands (the additional-rate CGT supplement applies only to residential property).

Worked example 3 - Helen and David the £500,000-portfolio couple (basic-rate + state-pension-only)

Helen age 66 is a basic-rate retiree with a £400,000 portfolio (mostly ISA and GIA dividend-payers plus a £100,000 SIPP). Helen's adjusted income is £25,000 (SIPP drawdown + GIA dividend income). David age 70 is a state-pension-only retiree with a £100,000 portfolio (mostly GIA dividend-payers). David's adjusted income is £12,000 (state pension only, just at the personal-allowance threshold). Combined household portfolio: £500,000. Combined household dividend income: ~£14,000/year (mix of ISA and GIA dividend income).

Current allocation. Most GIA dividend-paying holdings sit in Helen's name (because she has been the primary investor during their working years). Helen's dividend bill on her £10,000 GIA dividend: £500 dividend allowance + £9,500 × 8.75% (basic-rate) = £500 + £831.25 = £1,331.25/year. David's dividend bill: £0 (his dividend allowance is unused).

Bed-and-spouse shift. Shift £8,000 of dividend-paying GIA holdings from Helen to David. David is state-pension-only with income below the personal-allowance threshold, so his £500 dividend allowance absorbs the first £500 at 0%, and the remaining £7,500 is taxed at 0% within the basic-rate personal-allowance band. Helen was paying 8.75% on the £8,000. David pays 0%. Total household saving: £700/year (8.75% × £8,000).

Why the saving is straightforward. Helen's full 8.75% basic-rate dividend-tax is saved; David pays 0% because his income is below the personal-allowance threshold and his £500 dividend allowance covers the first £500 at 0%. For basic-rate to state-pension-only couples, the bed-and-spouse saving is essentially the full 8.75% basic-rate dividend-tax on the shifted amount.

Interaction with the marriage-allowance transfer. Helen could also receive £1,260 of David's unused personal allowance via the marriage-allowance transfer, saving approximately £252/year on her non-dividend income. The two levers stack: the marriage-allowance transfer on the personal-allowance side and the bed-and-spouse transfer on the dividend side. For couples where one spouse is state-pension-only, the combined marriage-allowance + bed-and-spouse framework can save £1,000-£2,000/year on a £500,000 household portfolio.

Documentation. Record the transfer. David's £500 dividend allowance covers the first £500 of new dividend income at 0%. The remaining £7,500 sits in David's basic-rate band at 8.75% but is sheltered by his personal allowance (David has £570 of unused personal allowance at £12,000 state pension). So in practice the entire £8,000 of new dividend income is tax-free.

Worked example 4 - Helen and James the £2,000,000-portfolio couple (additional-rate + higher-rate)

Helen age 72 is an additional-rate retiree with a £1,200,000 portfolio (mostly GIA dividend-payers plus a £500,000 SIPP). Helen's adjusted income is £180,000 (large SIPP drawdown + GFA dividend income). James age 75 is a higher-rate retiree with a £800,000 portfolio (mostly ISA and GIA dividend-payers plus a £200,000 SIPP). James's adjusted income is £55,000 (SIPP drawdown + GIA dividend income). Combined household portfolio: £2,000,000. Combined household dividend income: ~£80,000/year.

Current allocation. Most large dividend-paying GIA holdings sit in Helen's name (because she has been the higher earner during their working years). Helen's dividend bill on her £50,000 GIA dividend: £500 dividend allowance + £49,500 × 39.35% = £500 + £19,478.25 = £19,978.25/year. James's dividend bill on his £30,000 GIA dividend: £500 dividend allowance + £29,500 × 33.75% = £500 + £9,956.25 = £10,456.25/year. Combined household dividend bill: £30,434.50/year.

Bed-and-spouse shift. Shift £25,000 of dividend-paying GIA holdings from Helen to James. After James's £500 dividend-allowance absorption, the remaining £24,500 saves 5.6 percentage points. Total household saving: £1,372/year.

Comparison to lever 1 (cross-spouse drawdown sequencing). Shifting SIPP drawdown from Helen to James (drawing from James's SIPP first) saves more on the drawdown side: shifting £25,000 of SIPP drawdown from Helen (additional-rate 45% effective marginal rate on income above £125,140) to James (higher-rate 40% marginal rate) saves ~£1,250/year (£25,000 × 5 percentage points). Combining the SIPP drawdown sequencing and the bed-and-spouse dividend shift could save £2,500-£3,000/year on a £2,000,000 household portfolio.

CGT documentation. Helen's original cost basis on the £25,000 of transferred holdings carries over to James. James uses his own £3,000 AEA against any eventual gain. If James sells at higher-rate in 5 years and the gain is £10,000 on the transferred holdings, the CGT bill is £10,000 - £3,000 × 24% = £1,680 (the CGT rate is the same at higher-rate and additional-rate for shares).

5. The 5-rule cross-spouse dividend-allocation decision framework

The 5-rule cross-spouse dividend-allocation decision framework is the decision tree that operationalises the bed-and-spouse CGT-exempt transfer framework. Couples applying all 5 rules have a strong cross-spouse dividend-allocation framework; couples applying only rules 1-2 have a weak one.

Rule 1 - Identify the marginal-rate split. Identify each spouse's marginal-rate band (ordinary/basic/higher/additional) for the current tax year. The split determines the per-£10,000 saving potential. For Sarah-and-James in worked example 1: Sarah is basic-rate, James is higher-rate, the per-£10,000 saving is £2,500. For Margaret-and-Tom in worked example 2: Margaret is additional-rate, Tom is higher-rate, the per-£10,000 saving is £560. For Helen-and-David in worked example 3: Helen is basic-rate, David is state-pension-only, the per-£10,000 saving is £875. For Helen-and-James in worked example 4: Helen is additional-rate, James is higher-rate, the per-£10,000 saving is £560.

Rule 2 - Allocate dividend-paying GIA holdings to the lower-marginal-rate spouse. Shift the dividend-paying GIA holdings to the spouse with the lower dividend-tax rate. For basic-rate + higher-rate couples, shift to the basic-rate spouse. For additional-rate + higher-rate couples, shift to the higher-rate spouse. For higher-rate + basic-rate + state-pension-only tri-spouse situations (rare but possible in second marriages), shift to the state-pension-only spouse first (highest saving), then the basic-rate spouse, only keeping holdings with the higher-rate spouse when needed for diversification.

Rule 3 - Apply the timing interaction. Time the bed-and-spouse transfer to coincide with the ex-dividend date or just after the dividend is paid (so the new dividend is paid to the new owner's account). Avoid transfers during the 30-day window before the ex-dividend date out of an abundance of caution - bed-and-spouse is NOT subject to the 30-day bed-and-breakfast anti-avoidance rule (which only applies to bed-and-ISA), but the convention is to avoid the ex-dividend window for clarity and to avoid any HMRC challenge.

Rule 4 - Reconcile the cross-spouse allocation annually. The marginal-rate split may change year-on-year (for example, if one spouse takes a larger SIPP drawdown in one year, or if one spouse's state pension starts and pushes them into a higher band, or if one spouse's dividends fall and they drop into a lower band). Review the bed-and-spouse allocation annually and re-allocate if the marginal-rate split has shifted. The annual review should occur in the first 2-3 months of the new tax year, once both spouses' prior-year income is fully reconciled.

Rule 5 - Document the donor's cost basis. The receiving spouse inherits the donor's cost basis. Keep written records of the transfer (date, holding, number of shares, donor's cost basis, donor's acquisition date, donor's incidental costs) for future CGT calculation on disposal. The records should be retained for at least 2 years after the eventual disposal (HMRC's CGT investigation window), but the practical retention period is the lifetime of the holding plus 2 years.

Decision-tree output. Couples applying all 5 rules have a strong cross-spouse dividend-allocation framework. Couples applying rules 1-3 but failing rule 4 (not reconciling annually) have a moderate framework, because the marginal-rate split may have shifted without the allocation being updated. Couples applying rules 1-2 only (no timing, no documentation) have a weak framework, because the future CGT documentation is missing or the dividend is paid to the wrong account. Couples failing rule 1 (not knowing the marginal-rate split) have no cross-spouse dividend-allocation framework at all.

6. The interaction with 4 related articles

The bed-and-spouse CGT-exempt transfer framework is not standalone. It overlaps with 4 existing or drafted DividendMapper articles, each of which covers a complementary framework.

• The couple-coordinated-dividend-drawdown-uk-investors article (item 155, drafted 2026-07-14) covers the broader couple-level drawdown framework with the personal-allowance stacking, state-pension timing, cross-spouse dividend allocation, and cross-spouse SIPP drawdown sequencing. The bed-and-spouse framework extends this with the standalone Section 1K TCGA 1992 mechanic, the cost-basis carryover rule, the no-step-up-at-transfer convention, and the explicit CGT-side accounting for the future disposal.

• The two-spouse-isa-contribution-ordering-uk-dividend-investors article (item 133, drafted 2026-07-07) covers the cross-spouse ISA contribution framework. The bed-and-spouse article covers the cross-spouse GIA dividend-allocation framework - the natural GIA-side complement. Couples using the two-spouse-ISA-contribution-ordering framework to maximise ISA headroom should then use the bed-and-spouse framework to allocate the remaining GIA dividend income to the lower-marginal-rate spouse.

• The dividend-retirement-drawdown-order-uk-dividend-investors article (item 129, audited-and-passed) covers the per-retiree drawdown-order framework (the wrapper drawdown sequence: ISA first, then SIPP, then GIA). The bed-and-spouse article extends this with the cross-spouse allocation framework that operates before drawdown begins. Couples using the dividend-retirement-drawdown-order framework at drawdown can layer the bed-and-spouse framework on top to optimise which spouse holds which GIA holdings before the drawdown cascade starts.

• The dividend-portfolio-rebalancing-uk-income-investors article (item 153, drafted 2026-07-12) covers the per-wrapper rebalancing framework. The bed-and-spouse article extends this with the cross-spouse rebalancing framework that operates across both spouses' GIA wrappers. Couples using the dividend-portfolio-rebalancing framework to maintain target asset allocation can layer the bed-and-spouse framework on top to allocate the dividend-paying GIA portion of the rebalanced portfolio to the lower-marginal-rate spouse.

• The bed-and-isa-uk-dividend-investors article (item 137, drafted 2026-07-09) covers the bed-and-ISA framework with the 30-day anti-avoidance rule. The bed-and-spouse framework is the GIA-side complement with no 30-day rule. Couples using the bed-and-ISA framework for ISA-stocking can use the bed-and-spouse framework for GIA dividend-allocation in the same tax year, with no overlap.

7. What UK dividend investors should actually do with this

A practical 6-step cross-spouse dividend-allocation workflow:

1. Identify the marginal-rate split (ordinary/basic/higher/additional) for both spouses for the current tax year. Use the prior-year SA302/201 form as the starting point, then adjust for known changes (SIPP drawdown, state pension starts, etc.) for the current year. The split determines the per-£10,000 saving potential: £560/year (additional to higher), £2,500/year (higher to basic), £875/year (basic to dividend-allowance-only).

2. Calculate the per-£10,000 household tax saving potential under each shift pattern. Multiply the per-£10,000 saving by the household's expected GIA dividend income above the donor's £500 allowance. For Sarah-and-James in worked example 1: £2,500 × 2 = £5,000/year potential, of which £4,875/year is realised after Sarah's £500 dividend-allowance absorption. For Margaret-and-Tom in worked example 2: £560 × 1.5 = £840/year potential, of which £812/year is realised.

3. Identify the dividend-paying GIA holdings to transfer (typically the largest dividend-paying holdings). Bed-and-spouse works best for high-dividend-yield holdings (FTSE 100 / FTSE 250 dividend payers yielding 4%-7%) and is less impactful for low-yield growth holdings. Choose holdings that maximise the per-shifted-£10,000 dividend income.

4. Time the bed-and-spouse transfer for a tax-efficient moment (after the dividend is paid, before the next ex-dividend date). Avoid transfers during the 30-day window before the ex-dividend date out of an abundance of caution. The optimal timing is the day after a dividend is paid, so the next dividend cycle's payment goes to the new owner.

5. Document the donor's cost basis, donor's acquisition date, and transfer date for future CGT calculation. Record the holding identifier, number of shares, donor's original cost basis per share, donor's acquisition date, donor's incidental costs, and transfer value (market value at transfer date). Retain the documentation for the lifetime of the holding plus 2 years (the HMRC CGT investigation window).

6. Reconcile the cross-spouse allocation annually as the marginal-rate split may change year-on-year. Re-evaluate in the first 2-3 months of the new tax year once both spouses' prior-year income is fully reconciled. Common triggers for re-allocation: a spouse's state pension starts (drops them into a different band), a spouse takes a one-off SIPP drawdown, a spouse's dividend income falls below their £500 allowance, a spouse retires fully and their marginal rate drops.

Frequently Asked Questions

1. What is bed-and-spouse?

Bed-and-spouse is the transfer of GIA holdings between spouses or civil partners without triggering a CGT disposal, under Section 1K Taxation of Chargeable Gains Act 1992. The receiving spouse takes the donor's cost basis (no CGT step-up at transfer). After the transfer, future disposals are taxed at the receiving spouse's own marginal rate. Bed-and-spouse is the cleanest mechanism for the cross-spouse dividend-allocation framework.

2. What is the statutory basis for the bed-and-spouse CGT exemption?

The spouse-couple CGT exemption is set out in Section 1K of the Taxation of Chargeable Gains Act 1992. It applies to transfers between spouses or civil partners living together in the same tax year. Transfers between unmarried partners do not qualify. The exemption removes what would otherwise be a CGT disposal on the donor's side, and the receiving spouse inherits the donor's cost basis.

3. How much can I save per £10,000 transferred?

For higher-rate to basic-rate shift: £2,500/year per £10,000 (25 percentage-point difference x £10,000). For additional-rate to higher-rate shift: £560/year per £10,000 (5.6 percentage-point difference x £10,000). For basic-rate to dividend-allowance-only shift: £875/year per £10,000 (8.75 percentage-point difference x £10,000, assuming the recipient's £500 dividend allowance is unused). For higher-rate to state-pension-only shift, the saving is up to £3,375/year per £10,000 (33.75 percentage-point difference x £10,000).

4. Does bed-and-spouse trigger a CGT event?

No. Bed-and-spouse is not treated as a CGT disposal. The donor's unrealised gain migrates to the receiving spouse without crystallisation. The donor's acquisition date and incidental costs are preserved. The receiving spouse takes the donor's cost basis.

5. Can I transfer part of a holding?

Yes. Bed-and-spouse can be used to transfer part of a holding (for example, 200 of 1,000 shares in a particular FTSE 100 dividend payer). The receiving spouse's cost basis on the partial transfer is (donor's average cost per share x number of shares transferred). The donor retains the remainder at the original cost basis.

6. What is the cost-basis carryover rule?

The cost-basis carryover rule means the receiving spouse inherits the donor's cost basis (no revaluation at transfer, no step-up). The donor's acquisition date is preserved. The donor's incidental costs (broker fees, stamp duty) are preserved. When the receiving spouse eventually sells, the gain is calculated as (sale price - donor's cost basis) and taxed at the receiving spouse's marginal rate.

7. What is the difference between bed-and-spouse and bed-and-ISA?

Bed-and-ISA sells shares at a gain and rebuys them within an ISA within 30 days, crystallising the gain (with the 30-day anti-avoidance rule) and moving future dividend and growth into the ISA wrapper (tax-free). Bed-and-spouse does not crystallise a gain (no 30-day anti-avoidance rule) and does not move the holding into the ISA wrapper - it stays in GIA but with the dividend-tax liability shifting to the receiving spouse.

8. Can I do bed-and-spouse with my civil partner?

Yes. The Section 1K TCGA 1992 spouse-couple CGT exemption applies to transfers between spouses OR civil partners living together in the same tax year. Civil partners must have registered their partnership under the Civil Partnership Act 2004. Same-sex marriages are treated as marriages for Section 1K purposes.

9. What happens if my spouse and I divorce?

For bed-and-spouse transfers made during marriage, the receiving spouse retains the donor's cost basis even after divorce. For transfers made AFTER divorce under a court-ordered settlement, the receiving spouse takes the market-value-at-transfer cost basis (a step-up from the donor's basis). This is a different rule and can be advantageous (step-up) or disadvantageous (lower future CGT base) depending on circumstances.

10. Do I need to inform HMRC of a bed-and-spouse transfer?

No. Bed-and-spouse transfers are not reportable to HMRC at the time of transfer. The receiving spouse reports the holding on their own tax return if and when they dispose of it, using the donor's cost basis as the acquisition cost. Keep the donor's original purchase records and the transfer documentation for HMRC's CGT investigation window (2 years from the end of the tax year of disposal).

11. Can I use bed-and-spouse to allocate SIPP holdings?

No. SIPP holdings are held in a trust (the SIPP wrapper is a trust-based pension arrangement) and cannot be transferred between spouses without breaking the SIPP wrapper rules. Bed-and-spouse applies to GIA holdings only. For cross-spouse SIPP drawdown sequencing, see the couple-coordinated-dividend-drawdown-uk-investors article (item 155).

12. How does the marriage-allowance transfer interact with bed-and-spouse?

The marriage-allowance transfer (£1,260 of personal allowance shift, ~£252/year saving) operates on the personal-allowance side and stacks with bed-and-spouse (which operates on the dividend-tax side). For couples where one spouse is a non-taxpayer (income below £12,570), both levers can be applied in the same tax year. The marriage-allowance transfer is applied for via the GOV.UK marriage-allowance-transfer claim; the bed-and-spouse transfer is executed by changing the broker registration on the GIA holding.
