When it comes to CGT property transfer to spouse, the rules are generally favourable for married couples and civil partners. Understanding these exemptions can save you thousands in capital gains tax and help with property portfolio planning.

The key rule is straightforward: transfers between spouses and civil partners who live together are typically exempt from capital gains tax. But there are important exceptions and considerations you need to know about.

The No Gain, No Loss Rule

Under UK tax law, when you transfer property to your spouse or civil partner, the transaction is treated as taking place at "no gain, no loss". This means:

  • No capital gains tax is payable on the transfer
  • Your spouse acquires the property at your original base cost
  • They inherit your acquisition date for CGT purposes
  • Any future disposal will calculate gains from your original purchase price

For example, if you bought a buy-to-let property for £200,000 in 2020 and transfer it to your spouse in 2025 when it's worth £280,000, there's no CGT to pay. Your spouse's base cost becomes £200,000, not the current market value.

When CGT Property Transfer to Spouse Isn't Exempt

The exemption doesn't apply in all situations. Key exceptions include:

Separated Couples

If you're separated and no longer living together, transfers are treated as disposals at market value. CGT becomes payable on any gain since your original purchase.

However, you have until the end of the tax year of separation to make exempt transfers. If you separated in January 2025, you have until 5 April 2025 to transfer property without CGT implications.

Non-Resident Spouses

Special rules apply when transferring property to a non-UK resident spouse. The transfer may trigger CGT if the property has gained value, particularly for UK residential property under the non-resident capital gains tax rules introduced in 2015.

Business Property Reliefs

If the property qualifies for business asset disposal relief or other CGT reliefs, transferring to a spouse might not always be the most tax-efficient option. Your spouse won't automatically inherit your relief entitlements.

Practical Planning Considerations

The CGT property transfer to spouse exemption offers several planning opportunities:

Income Tax Planning

Transferring rental properties can help balance rental income between spouses, potentially reducing the overall tax burden. This is particularly valuable given Section 24 mortgage interest restrictions.

For instance, if one spouse is a higher-rate taxpayer paying 40% on rental profits while the other has unused basic rate band, transferring properties can reduce the family's total tax bill.

CGT Annual Exemptions

Each spouse has their own CGT annual exempt amount (£3,000 for 2024/25). Transferring properties before disposal can effectively double your available exemptions.

A couple with a property portfolio worth £500,000 more than the original cost could potentially save £1,200 annually by using both CGT allowances when selling properties.

How to Make the Transfer

Property transfers between spouses require proper documentation:

  • Transfer deed (TR1 form) signed by both parties
  • Land Registry application to change ownership
  • Mortgage lender consent if there's an outstanding loan
  • Update insurance policies and rental agreements

While no CGT is payable, you still need to keep records of the original purchase price and transfer date for future calculations.

What About Stamp Duty?

Transfers between spouses are generally exempt from stamp duty land tax (SDLT), provided no money changes hands. The transfer must be for "no chargeable consideration" to qualify for this exemption.

If you're transferring property as part of a financial settlement where one spouse pays the other, SDLT may become payable on the consideration received.

Record Keeping and Future Disposals

Even though the CGT property transfer to spouse is exempt, maintain detailed records:

  • Original purchase documentation and costs
  • Transfer documents and dates
  • Enhancement expenditure invoices
  • Professional fees related to the transfer

When your spouse eventually sells the property, they'll need this information to calculate any CGT liability based on the original acquisition cost and date.

Getting Professional Advice

While the basic rules around CGT property transfer to spouse are straightforward, property portfolios can involve complex situations. Factors like mixed-use properties, overseas elements, or business structures need careful consideration.

If you're planning transfers as part of broader tax planning or have properties held through companies, speak to a specialist property tax advisor. They can help ensure you're maximizing available exemptions while avoiding unexpected tax charges.
