Separating couples get three full tax years after the tax year of separation to transfer assets between themselves without triggering capital gains tax, and transfers made under a court order have no time limit at all. That is the no gain no loss rule in section 58 of the Taxation of Chargeable Gains Act 1992, as extended by the Finance Act 2023, and using it well can save a divorcing couple tens of thousands of pounds. This guide is written for couples divorcing in England and Wales, although CGT itself works the same across the UK.
Our capital gains tax and divorce hub covers the overview. This post goes deeper into the mechanics: exactly when the window opens and closes, how the court order route removes the deadline, how private residence relief protects the family home, and two fully worked examples using 2026/27 figures, with the £3,000 annual exempt amount and the 18% and 24% residential rates.
Because the tax turns on which assets move and when, it pays to know what a realistic split looks like before you plan any transfers. The settlement range estimator shows the range of outcomes a court would likely approve for your asset pot, so you can sequence transfers inside the window rather than discovering the deadline after it has passed.
How no gain no loss works when a divorce splits the assets
Married couples and civil partners who live together can pass assets between each other without CGT: the transfer is deemed to happen at a value that produces neither a gain nor a loss. The receiving spouse inherits the other's original base cost, so the tax is deferred rather than cancelled, and it crystallises when the asset is finally sold to the outside world.
Separation used to switch this off almost immediately. Before April 2023, the treatment lasted only to the end of the tax year in which a couple stopped living together, so a couple separating in March had weeks to reorganise their finances. The Finance Act 2023 rewrote the rule. As HMRC's guidance on CGT, separation and divorce confirms, transfers now qualify automatically until the end of the third tax year after the tax year of separation, and with no time limit where the transfer is part of a formal divorce agreement or court order.
The CGT timetable on divorce: three windows compared
| When the transfer happens | CGT treatment | What you need |
|---|---|---|
| By the end of the third tax year after the tax year of separation | No gain no loss, automatic | Nothing beyond the transfer itself |
| After that window, under a court order or formal divorce agreement | No gain no loss, no time limit | A consent order or other formal agreement covering the transfer |
| After that window, with no order or agreement | Disposal at market value; CGT can be due even though no money changes hands | Nothing protects you; gains above £3,000 taxed at 18% or 24% for residential property |
Two timing details matter. First, the window is measured in tax years, not calendar years: separate on 1 April and you get barely three years; separate on 30 April and you get almost four, because the clock only starts at the end of that tax year. Second, if the court grants your final divorce order before the three years are up, the automatic window can close early, which is another reason the order route below does the heavy lifting in most real settlements.
Court orders make the financial settlement window unlimited
Any transfer made under a court order, including a consent order recording an agreed financial settlement, qualifies for no gain no loss treatment whenever it happens. A property that takes two years to remortgage into one name, or shares released in stages, stay protected as long as the transfers trace back to the order.
This lines up with the legal advice you will hear anyway: an informal agreement does not end financial claims between ex-spouses, and it does not protect your tax position either. A sealed consent order with a clean break does both jobs for a £62 court fee. If you are still shaping what the split should be, the financial settlement guide covers what a court expects to see. One asset class sits outside all of this: pension sharing under a court order is not a CGT disposal at all, as explained in pension sharing versus offsetting.
Private residence relief and the family home
For most couples the family home is the biggest asset, and private residence relief usually shelters it. The spouse who stays in the home until it is sold or transferred normally has full relief. The spouse who moves out accrues a chargeable period, softened by two rules: the final 9 months of ownership are always exempt, and the gain is time-apportioned over the whole ownership period, so short gaps cost little.
There is also a targeted fix in TCGA 1992 s.225B. Where the departing spouse transfers their interest to the ex who has stayed in the home, under a divorce agreement or court order, they can elect to be treated as still occupying it, preserving full relief for the gap. The election only works for a transfer to the ex, not an open market sale, and it stops the departing spouse claiming relief on another main residence for the same period.

Worked example 1: transferring a rental flat in the divorce settlement
Dan and Priya separated in June 2024, so the automatic window runs to 5 April 2028. They jointly own a buy-to-let bought for £160,000, now worth £260,000. In the settlement, Dan transfers his half share to Priya in 2026/27.
- Inside the window (or under their consent order): no gain no loss applies. Dan pays no CGT, files no 60-day return, and Priya takes over his £80,000 base cost for that half. The £50,000 gain on Dan's share is deferred, not erased: when Priya later sells the whole flat, she is taxed on the full gain from the original £160,000 cost.
- Outside the window with no order: Dan is treated as disposing of his half at market value, £130,000 against an £80,000 cost. Gain £50,000, minus the £3,000 annual exempt amount, leaves £47,000 taxable. As a higher rate taxpayer he pays 24%, a bill of £11,280, with any part of the gain falling inside his unused basic rate band taxed at 18% instead. He owes that within 60 days, on a transfer that raised no cash.
Same transfer, same flat, a difference of £11,280 purely on timing and paperwork.
Worked example 2: selling the family home after moving out
Mark and Elena bought their home in June 2014 for £310,000, owning it equally. Mark moved out in June 2023; the house sells to a third party in June 2026 for £550,000. Total gain £240,000, so £120,000 each.
- Elena lived there throughout, so private residence relief covers her £120,000 in full. No CGT, no 60-day return.
- Mark owned for 144 months and occupied for 108. Relief covers those 108 months plus the final 9, leaving 27 of 144 months chargeable: £120,000 times 27/144 = £22,500. Minus the £3,000 annual exempt amount leaves £19,500 taxable. At 24% that is £4,680. If £10,000 of his basic rate band were unused, the bill would be £1,800 plus £2,280, so £4,080.
Because this is a sale to a third party, the s.225B election cannot help Mark; it would only have applied if he had transferred his half to Elena under the settlement. Mark must report and pay within 60 days of completion.
60-day CGT reporting after divorce transfers and sales
Any disposal of UK residential property with CGT due must be reported, and the tax paid, within 60 days of completion through HMRC's UK property account, as set out in the gov.uk reporting rules. That catches Mark's sale above, and any transfer between ex-spouses that falls outside both the window and a court order. A pure no gain no loss transfer needs no 60-day return because no tax is due, and a fully relieved main home sale, like Elena's, does not either. Keep the base cost records regardless: HMRC's helpsheet HS281 confirms the receiving spouse computes their eventual gain from the original acquisition cost.
Getting the CGT timing right in your financial settlement
The mechanics reduce to three rules. Transfers within three tax years of the end of the separation tax year are automatically tax free. Transfers under a court order are tax free whenever they happen, which is one more reason to get a consent order rather than rely on an informal deal. And no gain no loss defers tax rather than cancelling it, so the built-in gain on any asset you keep should be priced into the deal itself.
