gains on UK property

non-resident capital gains tax

We file your UK CGT return within 60 days.

Three different bases are permitted for calculating a non-resident’s gain, and they rarely give the same answer. We compute all of them, elect the one that costs you least, and file the 60-day return before the clock runs out.

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

Do I pay UK capital gains tax if I live abroad?

Yes. Non-residents have been within the charge on UK residential property since 6 April 2015. Living overseas does not take a UK property sale outside the UK tax net.

How long do I have to report the sale?

What happens if I miss the 60-day deadline?

How is the gain actually calculated?

Do I still report it if I make a loss?

What if it used to be my home?

Do I also need to put it on my Self Assessment return?
