What is the 60-day CGT reporting deadline?

If you are a UK-resident living in the UK, then the HMRC 60-day reporting deadline applies to the sale of all UK residential property only, and if you have made a gain where tax is owed. If you have sold other land or property such as commercial, or if the property is located overseas, then the 60-day deadline will not apply. Instead, you will need to report the sale via Self Assessment which we can also help with.

What costs can I deduct?

Allowable costs typically include legal fees, estate agent fees, stamp duty, and the cost of capital improvements (e.g. extensions). Routine repairs aren't deductible against CGT.

Do I need to include the gain in my Self Assessment return as well?

In many cases, yes. Even if you file a 60-day CGT return, the gain must also be included on your Self Assessment tax return.

What if I made a loss?

Losses can usually be claimed and carried forward to offset future CGT gains. We ensure they are reported correctly so you don't lose the benefit. There is a strict 4-year time limit within which you must report losses to HMRC to be able to carry the loss forward.

Can you help if I already missed the deadline?

Absolutely – we can assist with late, overdue CGT returns if you have missed the 60-day filing deadline. We provide fast, professional assistance to help reduce penalties where possible.

What is the annual exemption for CGT?

For the 2026/27 tax year, the annual exemption for CGT is only £3,000. This CGT annual exemption is separate to the income tax free allowance which you may be using against your wages, pensions, or rental income.

What if the property is located overseas?

Any land or property located anywhere in the world, must be calculated and reported for CGT when you sell. The only difference is when the deadline will be; for property located outside of the UK then the 60-day filing deadline does not apply, but you may still owe tax on the sale.

Expert support with UK and overseas property disposals & CGT reporting

Selling or disposing of any land or property located anywhere in the world can trigger a Capital Gains Tax (CGT) liability, which might be the biggest tax bill you ever face.
‍
For all UK residents who are living in the UK, and have sold a residential property located in the UK, you have just 60 days from the date your sale completes to calculate the gain, report the property disposal to HMRC if applicable, and pay any capital gains tax due.

At UK Tax Returns, we are specialist capital gains tax accountants, and we can guide you through every step of the process. We identify which costs qualify as deductible, assess your eligibility for Principal Private Residence (PPR)and other reliefs, and ensure your gain is calculated accurately so that you don’t pay more CGT than you need to. Our aim is to make the process clear, compliant, and stress-free to ensure that you do not miss the 60 day CGT filing deadline.

If you’re at the stage where you’re only thinking of selling, we can also advise on tax planning opportunities, helping you understand the impact of an anticipated sale and avoid unnecessary tax.

What can we do for you?

1. Assess whether or not your transaction is reportable for CGT, ensuring full compliance with HMRC rules.

2. Offer support with setting up your HMRC Capital Gains Tax account so your 60-day return can be filed without delays.

3. Advise you on which records and documents are required to support an accurate capital gains tax calculation.

Invaluable Knowledge & Outstanding Results

Fantastic service from Kelly again for both our annual UK tax return and for our Capital Gains Tax (CGT) reporting, following the sale of our UK property. Kelly's knowledge proved invaluable and the results she achieved went way beyond our expectations. As an expat living in Australia, I was slightly apprehensive about engaging a tax expert that I'd not met but Kelly has been awesome, really responsive and proved far better value than my previous London-based tax advisers.
