Specialist Support for UK Property Owners &Investors

Selling or disposing of a property or investment can trigger a Capital Gains Tax (CGT) liability which might be the biggest tax bill you ever face. For UK residential property, you now have just 60 days from completion to calculate the gain, report it to HMRC, and pay any tax due.  

At UK Tax Returns, we 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.

If you’re at the stage where you’re thinking of selling, we can also advise on tax planning opportunities, helping you understand the impact of the 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 documentsare required to support an accurate capital gains tax calculation.

4. Review your circumstances to identify any available expense, reliefs, allowances, or elections to help reduce your gain.

5. Calculate an accurate capital gains tax liability helping to ensure tax efficiency and compliance.

6. Submit your CGT return directly to HMRC, ensuring everything is filed correctly and on time

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.
