We've got an investment property we're looking to sell, owned jointly by me and my spouse. Can we both use our individual CGT allowances, or is it just one allowance per property sale? And does it make a difference who sells it?
Quick Answer
Both joint owners can use their individual £3,000 CGT allowances when selling investment property, provided they are UK taxpayers, effectively doubling the tax-free gain.
## Understanding Capital Gains Tax Allowances for Joint Property Sales
When selling an investment property held jointly, both you and your spouse can utilise your individual Capital Gains Tax (CGT) annual exempt amounts. For the 2026/27 tax year, this allowance is £3,000 per person, meaning a married couple or civil partners selling a jointly owned property could effectively exempt up to £6,000 of the total capital gain from tax. This is a significant consideration for tax planning as it directly reduces the taxable gain. HMRC guidance explicitly states that each individual taxpayer is entitled to their own annual exempt amount, regardless of how many properties they sell within a tax year, provided they are the legal owner.
### How is the Gain Split Between Spouses?
The allocation of the capital gain typically follows the ownership split of the property. If you and your spouse own the investment property as joint tenants or tenants in common in equal shares (e.g., 50/50), then the capital gain will usually be split equally. Each spouse then applies their £3,000 annual exempt amount to their respective share of the gain. For instance, if a property sold for a £50,000 gain and was owned 50/50, each spouse would have a £25,000 gain. After applying their individual £3,000 allowance, each would be taxed on £22,000.
However, it's possible for spouses to elect to split the beneficial ownership in different proportions, even if the legal title is held as joint tenants. This would require a declaration of trust to HMRC, and any subsequent gain would be allocated according to these declared beneficial interests. This flexibility can be beneficial if one spouse has a significantly lower income, allowing more of the gain to be taxed at the 18% basic rate of CGT, rather than the 24% higher/additional rate, for example. The timing of this declaration is important; it must be made before the sale to be effective.
### Does it Make a Difference Who Sells the Property?
It does not make a difference who physically sells the property, as the legal ownership structure dictates how the gain is attributed for tax purposes. If the property is solely in one spouse's name, only that spouse can utilise their annual exempt amount and will be liable for the CGT. Transferring ownership to a spouse before sale to utilise both allowances is generally permissible, as transfers between spouses are exempt from CGT. However, the spouse receiving the share of the property takes on the original cost base, and Stamp Duty Land Tax (SDLT) implications should be considered if there is an outstanding mortgage. For example, if a property solely owned by one spouse with a £200,000 mortgage is transferred to joint names, the transferee's share of the mortgage (e.g., £100,000) could trigger SDLT, which would be 5% on the portion over £125,000 if it's an additional dwelling, costing £1,250 on the £100,000 share.
Furthermore, the income tax rates of each spouse are critical. Basic rate taxpayers pay 18% CGT on residential property, while higher or additional rate taxpayers pay 24%. By allocating more of the gain to the spouse who remains a basic rate taxpayer even after adding the gain to their income, the overall CGT liability for the couple can be reduced. This strategic allocation, facilitated by a declaration of trust, must be genuinely reflective of the beneficial ownership and should be considered well in advance of a sale.
## Benefits of Utilising Both CGT Allowances
* **Increased Tax-Free Gain:** Each spouse can use their £3,000 annual exempt amount, effectively doubling the tax-free portion of the gain for jointly owned properties.
* **Potential for Lower Tax Rate:** Strategically allocating beneficial ownership can allow more of the gain to fall within a spouse's basic rate income tax band, leading to an 18% CGT rate instead of 24%.
* **Reduced Overall Liability:** Leveraging both allowances and tax bands can significantly lower the total Capital Gains Tax payable on the property sale, improving net proceeds.
## Considerations When Planning Your Sale
* **Timing of Transfers:** Any transfers of ownership between spouses must occur before the property sale completes to be effective for CGT purposes.
* **SDLT Implications:** Be aware that transferring property shares where an outstanding mortgage exists can trigger Stamp Duty Land Tax (SDLT) on the mortgage value if it exceeds the base residential thresholds, such as the 5% additional dwelling rate on portions over £125,000.
* **Declaration of Trust:** If you intend to split beneficial ownership unequally, a formal Declaration of Trust should be executed and potentially registered with HMRC.
## Investor Rule of Thumb
Always assume each spouse can use their individual CGT allowance for jointly owned property sales, and proactively plan the ownership split to optimise against each spouse's income tax band.
## What This Means For You
Understanding how to correctly apply CGT allowances for jointly owned properties can save you thousands in tax. Many investors overlook the potential to optimise their tax position by not considering how beneficial ownership is split or the impact of each spouse's income tax rate.

Steven's Take
From my experience, property investors often focus on acquisition, but tax planning for disposals is equally crucial. The ability for each spouse to use their individual £3,000 CGT allowance on a jointly owned property is a fundamental principle. However, smart investors go a step further. By strategically adjusting beneficial ownership via a declaration of trust before a sale, you can potentially allocate more of the gain to the spouse who falls into the basic rate tax bracket, paying 18% CGT instead of 24%. This requires careful timing and understanding of HMRC rules, but the savings can be substantial, especially on larger gains.
