Emma did an amazing job and helped me realize because I wasn’t living in the UK I could save a lot in taxes. I am really impressed at how she operated and guided me through the whole process, doing the majority of the work.

Calculation and return, start to finish
Our specialist CGT advisors help navigate the non-resident capital gains tax requirements and meet the 60-day HMRC reporting requirement.
The 60-day rule
The clock starts at completion, not exchange
Sixty days to calculate the gain, file the return and pay the tax. It applies even when no tax is due.
Day 0
Completion
The sale completes and the clock starts. Exchange does not count — completion does.
Day 1–59
Compute & elect
Gather costs, establish the base cost, run all three bases and elect the one that costs least.
Day 60
File & pay
The non-resident CGT return submitted and the tax paid. Both are due, not just the return.
Day 61+
Penalties & interest
Late filing penalties begin and escalate, with interest running on the tax from the due date.
The process
Completion to filed return, comfortably inside 60 days.

FAQs
Questions we get from expats about CGT returns
Who can help me with Capital Gains Tax on UK property as a non-resident?
A UK tax adviser who specialises in non-residents can work out your gain, claim any reliefs and file the 60-day return through your Capital Gains Tax on UK property account. Global Tax Consulting does this for people living abroad. Founder Emma McDermott ATT, formerly of Deloitte, calculates the gain on every permitted basis, uses the one that gives the lowest tax and files the return for you. The fee is typically £750, fixed before we start. Start as soon as you have a completion date, because the 60 days run from completion, not exchange.
How long do I have to report the sale?
Sixty days from completion — not from exchange. The return and the payment are both due inside that window, and the obligation applies even where no tax is payable.
What happens if I miss the 60-day deadline?
Late filing penalties start immediately and escalate, and interest runs on the tax from the due date. It is still far better to file late than not at all, and there are grounds on which penalties can sometimes be reduced.
How is the gain actually calculated?
Three bases are permitted: rebasing to the April 2015 value, time apportionment of the whole gain, or the whole gain since purchase. You can elect between them, and the difference is often tens of thousands of pounds.
Do I still report it if I make a loss?
A non-resident CGT return is generally still required on a disposal of UK property even where the result is a loss or no tax is due. Reporting the loss also preserves it for use against future gains.
What if it used to be my home?
Private residence relief may cover the period you lived there, plus the final period of ownership, which can remove a substantial part of the gain. Whether it applies depends on the facts of your occupation.
Do I also need to put it on my Self Assessment return?
If you are already within Self Assessment, the disposal goes on your annual return as well as the 60-day report, with the tax already paid credited against the final position.
