Separating from a spouse or civil partner is rarely just an emotional process, it's a financial one too. Once you start untangling a shared life, tax quickly becomes one of the most overlooked parts of the picture. Who pays what, when assets move between you, can meaningfully change the final settlement.
I'm Brad Askew, and over the years I've seen plenty of couples reach an agreement on paper only to discover a tax bill they hadn't planned for. This guide walks through the main tax areas that tend to come up during a UK divorce, Capital Gains Tax, Inheritance Tax, Stamp Duty Land Tax and pensions, so you can spot the issues early and make decisions with your eyes open.
It isn't a substitute for speaking to someone about your own circumstances, but it should give you a solid grounding before you do.
Overview
When a marriage or civil partnership breaks down, the couple typically needs to divide assets such as the family home, savings, investments, pensions and sometimes business interests. Each of those transfers can trigger a tax consequence depending on timing, who owns what, and how the split is structured.
While married, couples benefit from several generous tax rules, most notably the 'no gain, no loss' treatment for Capital Gains Tax on transfers between spouses. Once separation happens, some of those protections begin to fall away, and the calendar starts to matter a great deal.
Reforms introduced from 6 April 2023 extended the window in which separating couples can move assets between themselves without an immediate CGT charge, which has taken some of the pressure off divorces that stretch over multiple tax years. Inheritance Tax, stamp duty on property transfers, and the treatment of pensions each follow their own rules.
Understanding how these interact with your financial settlement can make a real difference to what each party actually walks away with.
Key steps
- Map out every asset and who legally owns it. Before you can think about tax, you need a clear picture of what's on the table. List the family home, any second properties, investments, savings, pensions, business interests and significant personal assets, noting sole or joint ownership. Ownership dictates who is making the disposal for tax purposes.
- Note the date of separation and keep it in mind. The tax year in which you separate matters because several reliefs are measured from that point. Keep a record of when you stopped living together as a couple, as this is the trigger date for the extended 'no gain, no loss' window on Capital Gains Tax and affects other reliefs too.
- Consider Capital Gains Tax before transferring assets. Transfers of assets between separating spouses can generate a CGT charge depending on timing and the nature of the asset. The family home may qualify for Private Residence Relief, while investments and second properties often will not. Work out the position before moving anything rather than after.
- Check Stamp Duty Land Tax on property changes. When the family home or another property is transferred as part of a divorce settlement, SDLT treatment depends on whether the transfer is made under a court order or formal agreement. Transfers pursuant to a divorce order are commonly exempt, but informal arrangements may not be, so the paperwork matters.
- Address pensions carefully, they are often the largest asset. Pensions can be shared, offset or earmarked as part of a financial settlement. Each route has different long-term tax consequences for both parties, and the value shown on a pension statement is rarely the value a court treats as relevant. Take this element seriously rather than trading it off against the house.

Common questions
Q When does Capital Gains Tax become an issue in divorce?
While you're married or in a civil partnership and living together, transfers between you are treated as 'no gain, no loss', so no CGT arises. Once you separate, that protection starts to narrow. Since April 2023, separating couples generally have up to three tax years from the end of the year of separation to transfer assets on a no gain, no loss basis, with longer treatment available for transfers made under a court order.
Q Will I pay CGT on transferring the family home to my ex?
The family home often qualifies for Private Residence Relief, which can remove or significantly reduce any CGT on a transfer. However, the relief depends on how long each spouse lived in the property as their main home and when they left. Where one spouse has moved out some time before the transfer, the position becomes more complex, and the outcome can differ between the two parties.
Q Is Stamp Duty payable when a property is transferred in a divorce?
Transfers of property between spouses or civil partners made as part of a divorce, dissolution or formal separation, typically under a court order, are usually exempt from Stamp Duty Land Tax. Informal transfers outside that framework may not qualify for the exemption, so it's worth checking how your settlement is structured before any transfer takes place.
Q How are pensions treated for tax in a divorce settlement?
Pensions can be dealt with by sharing, offsetting against other assets, or attaching a future income stream. A pension share transfers a portion of one spouse's pension into the other's name, generally without immediate tax consequences, though future drawdown will be taxed in the normal way. Offsetting can have hidden tax implications, because cash today and pension pounds in thirty years are not like-for-like.
Q Does Inheritance Tax apply to transfers during divorce?
Transfers between spouses are usually exempt from Inheritance Tax while the marriage subsists, and transfers made as part of a formal divorce settlement are generally not treated as gifts for IHT purposes. Once divorce is finalised, your ex-spouse is no longer a spouse for tax purposes, so later gifts between you fall under the ordinary IHT rules, including the seven-year rule on lifetime gifts.
Q What happens if we can't agree before the tax year ends?
The current rules give separating couples more breathing room than the old regime, so missing a single tax year end is rarely fatal. That said, timing still matters, particularly for assets standing at a significant gain. If negotiations are dragging on, it can be worth understanding which transfers are time-sensitive so that the order and date of transfers can be planned rather than left to chance.
Q Do I need a financial order from the court to get the tax reliefs?
Not always, but a court order, typically a consent order approving your financial agreement, gives the most robust footing for reliefs such as the extended CGT treatment and SDLT exemption on property transfers. Informal agreements between separating couples can work, but they don't carry the same protections and can leave one or both parties exposed to tax charges that could have been avoided.
