What tax considerations should I be aware of when selling a property during a divorce in the UK?

The main tax issues when selling a property during a divorce in the UK are Capital Gains Tax, the tax treatment of any transfer between spouses or civil partners, property-related income, and the reporting obligations created by the sale. The correct result depends on factors such as the property’s use, ownership structure, separation arrangements, mortgage and sale costs, and the terms of any financial order.

Establish who is taxable. The person or people with the beneficial ownership of the property are normally responsible for the tax arising from a disposal, rather than simply whoever is named on a form or who receives the sale proceeds. Beneficial ownership concerns who is entitled to the economic value of the property. This can differ from the legal title, particularly where one spouse contributed more to the purchase, the couple signed a declaration of trust, or a financial agreement allocates the proceeds in unequal shares.

Before accepting an offer, review the title register, declaration of trust, mortgage documents, previous financial agreements and any court order. The ownership position should be clear before the conveyancer prepares completion statements or the parties divide the proceeds.

Consider the date and nature of the disposal. For tax purposes, a disposal generally relates to the point at which an unconditional contract is made, although the precise treatment can depend on the contract and circumstances. This means that exchanging contracts and completing the sale can fall in different tax periods. The relevant date may affect which tax return includes the gain and whether other disposals or reliefs in that tax year are relevant.

A transfer from one spouse or civil partner to the other is not treated in exactly the same way as an ordinary sale to an unrelated buyer. The terms of the transfer, the date of separation and whether the transfer is made under a formal divorce or separation arrangement can affect the calculation. Obtain advice before transferring a share merely to simplify the sale, because a transfer may alter both the ownership history and the eventual gain calculation.

Calculate the gain using reliable records. A CGT calculation usually starts with the disposal proceeds and deducts the allowable acquisition and improvement costs. Costs that may need to be examined include:

• the original purchase price;
• certain legal, conveyancing and transaction costs connected with the purchase or sale;
• qualifying capital improvements, such as work that adds to or changes the property rather than ordinary repairs; and
• other allowable costs that are directly connected with establishing or disposing of the asset.

Keep invoices, completion statements, mortgage records and evidence of substantial improvement work. Mortgage interest and ordinary maintenance costs do not automatically qualify as deductions from a capital gain. A tax adviser can separate capital expenditure from revenue expenditure and check whether a claimed cost is allowable.

Check whether the property was the former matrimonial home. Relief for a main residence can be affected if either spouse moved out, the property was occupied by the other spouse, it was let, or it was used partly for business. The period covered by a relief and the way any remaining gain is divided can depend on the facts and the relevant separation arrangements. Do not assume that leaving the property permanently ends every possible relief, or that living there for part of the ownership period makes the whole gain exempt.

Keep evidence of occupation and use, including council tax records, utility bills, tenancy agreements, correspondence and dates of any move. Where one spouse remains in the home until sale, the tax position may differ from a case in which the property is vacant or rented after the other spouse leaves.

Account for rental or other income. If the property has been let, rental income normally needs to be considered separately from CGT. The person taxable on the rent may not always be the person handling the rent or receiving the sale proceeds. The couple should review the ownership declaration, rental records, allowable expenses and any property income already reported.

If part of the property was used for business or as an office, that use may also affect the availability of relief and the records needed to support the calculation. Short-term letting, lodgers and periods of vacancy should be identified rather than treated as ordinary private occupation.

Do not overlook transaction taxes on a transfer. A transfer of an interest in land between spouses or civil partners can raise Stamp Duty Land Tax in England and Northern Ireland, Land Transaction Tax in Wales, or Land and Buildings Transaction Tax in Scotland. The result may depend on whether money changes hands, whether the recipient takes responsibility for part of a mortgage, and whether the transfer is made under a court order or another formal divorce arrangement.

The tax treatment of a transfer under a divorce agreement is not necessarily the same as the treatment of an informal transfer between co-owners. Ask the conveyancer or a property tax adviser to check the rules for the part of the UK where the property is located before signing the transfer deed. A sale to an independent buyer will generally require a separate review of the relevant transaction tax position and of any mortgage repayment.

Allow for sale proceeds and financial settlements. Paying one spouse an amount from the sale proceeds does not, by itself, determine the CGT position. Tax is normally analysed by reference to the disposal and each person’s beneficial share, while the divorce settlement determines how the net assets are divided. A court order can allocate responsibility for tax between the parties, but that private allocation may not remove a person’s statutory liability to HMRC.

Ask the solicitor preparing the financial order to state clearly how tax liabilities, professional fees, mortgage redemption charges and other sale costs are to be dealt with. This avoids a disagreement where the proceeds are divided before the tax position has been calculated.

Meet reporting and payment requirements. Where a taxable gain arises on a UK residential property, there may be a requirement to report it to HMRC and pay any amount due within the statutory deadline for residential property disposals. The gain may also need to be included on a Self Assessment return, depending on the seller’s circumstances. The reporting obligation can apply even where the sale proceeds are immediately transferred to a former spouse under the divorce settlement.

Tax rates, reliefs and annual allowances can change, so use the rules applying in the relevant tax year rather than relying on an old calculation. Obtain written confirmation of the reporting position from a qualified tax adviser, especially where the property was jointly owned, rented, transferred before sale or held through a trust or company.

Prepare a tax file before completion. Gather the purchase and sale contracts, title documents, valuations, improvement invoices, estate agency or legal invoices, mortgage statements, evidence of occupation, rental accounts and the divorce or separation agreement. Keep a record of how the proceeds were divided and of any tax paid by either party. Clear records help the adviser calculate each person’s share and reduce the risk of relying on an unsupported estimate.

Because divorce can involve transfers, changing occupation, unequal ownership and court-ordered settlements at the same time, a solicitor’s advice should be coordinated with advice from a qualified tax adviser. They can check the CGT calculation, transaction taxes and reporting obligations before the sale completes.
