Capital Gains Tax on Divorce: What You Need to Know

This article is for information only. It does not constitute legal or tax advice. Tax rules can change, and your personal circumstances will affect the outcome. You should take independent financial or tax advice alongside legal advice when dealing with financial matters on divorce.

Divorce involves a great many financial decisions. One that often catches people off guard is capital gains tax (CGT). When you and your spouse divide assets, the tax implications can be significant — particularly if property, investments, or business interests are involved.

This guide explains how CGT works in the context of divorce, what reliefs may apply, and why the timing of your financial settlement matters more than most people realise. HMRC sets out the general rules in its guidance on capital gains tax.

What is capital gains tax?

Capital gains tax is a tax on the profit you make when you sell or transfer an asset that has increased in value. For example, if you bought an investment property for £200,000 and later transfer it to your spouse for £350,000, the ‘gain’ is £150,000. HMRC may tax that gain, depending on the circumstances.

CGT applies to a wide range of assets. These include second homes, buy-to-let properties, shares, unit trusts, and business assets. It does not typically apply to your main home, though divorce complicates that rule in ways worth understanding.

How does CGT work between spouses?

During a marriage, transfers of assets between spouses generally take place at ‘no gain, no loss’. In plain terms, this means HMRC treats the transfer as if no profit has been made, so no CGT bill arises at the point of transfer. HMRC explains how spouses and civil partners are treated in helpsheet HS281. This is a valuable relief — but it has a time limit.

That time limit is the issue. The ‘no gain, no loss’ rule only applies for as long as you are living together as a married couple. Once you separate, the clock starts ticking.

The separation date matters

Historically, the no gain, no loss window closed at the end of the tax year in which you separated. In practice, that could mean a window of just days or weeks — which was widely criticised as unfair.

However, the rules changed significantly from 6 April 2023. Under the new rules, separating spouses now have up to three years after the tax year of separation to transfer assets under no gain, no loss. In addition, where a transfer forms part of a formal divorce settlement, there is no time limit at all.

This change brought the law much closer in line with how long financial settlements actually take to negotiate and finalise. For many couples, it removes CGT as a source of undue pressure on settlement timelines.

The family home and CGT on divorce

The family home usually qualifies for Private Residence Relief (PRR). This relief means that any gain on a property that has been your only or main home throughout your ownership is free from CGT.

However, complications arise when one spouse leaves the family home before the property is sold or transferred. The departing spouse may no longer qualify for full PRR if they have been living elsewhere. As a result, a portion of any gain may become taxable.

The nine-year rule for divorcing spouses

Again, the rules changed in April 2023 to help separating couples. A spouse who has left the family home can now elect to treat it as their main residence for PRR purposes for up to nine years after they leave. This applies provided the property is eventually transferred to the remaining spouse or sold as part of the divorce settlement.

This is a meaningful protection. It means the departing spouse does not automatically face a CGT liability simply because they had to move out of the family home during a lengthy separation.

What CGT rate applies?

The rate of CGT depends on the type of asset and your level of income. For residential property, the rates are 18% for basic rate taxpayers and 24% for higher or additional rate taxpayers. For other assets, the rates are 18% for basic rate taxpayers and 24% for higher rate taxpayers. These rates apply from 30 October 2024, following changes announced in the Autumn Budget. Current rates and the annual exempt amount are published on the GOV.UK capital gains tax rates page.

Each individual also has a CGT annual exempt amount, which is the amount of gain you can make in a tax year before CGT applies. For the 2025/26 tax year, that amount is £3,000. This is significantly lower than it was in previous years, so the exemption provides less shelter than it once did.

Business assets and holdover relief

If business assets form part of your divorce settlement, further CGT rules may apply. Holdover relief allows the CGT charge on certain business assets to be deferred — ‘held over’ — until the receiving spouse eventually disposes of the asset. The gain does not disappear; instead, it transfers along with the asset.

This area of tax law is complex. In many cases, specialist tax advice alongside family law advice is essential to avoid unexpected liabilities.

CGT and the overall financial settlement

It is important to view CGT not in isolation, but as part of your overall financial settlement. A large pension share may look less attractive once you account for income tax on drawdown. Similarly, an asset that appears equal in value to another may carry a substantial deferred CGT liability that the other does not.

Family law solicitors work alongside accountants and financial advisers in many cases precisely for this reason. Therefore, building a full picture of each asset’s net value — after tax — is essential before agreeing any financial order.

What is a financial order?

A financial order (sometimes called a consent order if agreed by both parties) is the court document that makes your financial settlement legally binding. Courts in England and Wales require financial orders to be approved by a judge, even when the parties have reached agreement without going to court. A financial order protects both parties and prevents future claims. GOV.UK sets out the process in its guide to money and property when you divorce or separate.

The Mesher order and deferred sales

In some cases, the family home is not sold immediately. A Mesher order allows the property to remain unsold — typically until children reach a certain age or the resident spouse remarries. In those cases, CGT can be deferred until the eventual sale.

However, a Mesher order brings its own CGT considerations. By the time the property is sold, the non-resident spouse may no longer qualify for full PRR. Tax advice at the time of agreeing a Mesher order is therefore important, not an afterthought.

Taking professional advice on capital gains tax on divorce

CGT on divorce is not a topic to work out retrospectively. Decisions made during the settlement process — the timing of transfers, how assets are structured, and how the financial order is drafted — can all affect your tax position.

A family law solicitor can identify where CGT issues are likely to arise and refer you to specialist tax advice where needed. Tyrer Roxburgh Solicitors works with clients across England and Wales on financial settlements that consider the full picture, not just the headline numbers. If you are separating later in life, you may also find our guides to grey divorce after 60 and silver divorcees’ pension rights useful.

Frequently asked questions about capital gains tax on divorce

Do I have to pay capital gains tax when I transfer assets to my spouse on divorce?

Not necessarily, and not immediately. Transfers between spouses who have not yet separated take place on a no gain, no loss basis, meaning no CGT arises at the point of transfer. Since April 2023, separating spouses have up to three years after the tax year of separation to transfer assets under the same relief. Where a transfer is made under a formal divorce settlement, no time limit applies at all.

Does capital gains tax apply to the family home in a divorce?

In many cases, Private Residence Relief (PRR) will reduce or eliminate CGT on the family home, because it has been your main residence. However, complications arise if one spouse has moved out before the property is sold or transferred. The April 2023 rule changes now allow a departing spouse to claim PRR for up to nine years after leaving, provided the property is transferred or sold as part of the divorce settlement.

Can my spouse and I split a CGT liability between us?

The CGT liability generally falls on the person who owns the asset at the time of the disposal (sale or transfer). However, how you structure the financial settlement can affect which assets each party receives and therefore which party bears any future CGT exposure. For that reason, understanding the tax profile of each asset before finalising a settlement is important.

What if I transferred assets to my spouse before knowing about the CGT rules?

If a transfer has already taken place, it is worth taking professional tax advice as soon as possible to understand what liability, if any, has arisen. In some cases, the no gain, no loss rules will have applied and there may be no immediate liability. In others, a CGT charge may already have crystallised. A tax adviser can review the position and advise on next steps. Your family law solicitor can refer you to a suitable specialist.
