The Reviewed guarantee: typically filed in 1 to 3 working days, guaranteed within 5, once we have your documents, your accepted HMRC agent authorisation and your cleared identity (AML) checks. The clock pauses while we're waiting on you, or we refund the fee in full. Full terms.

What happens after you pay

  1. Upload your completion statement and purchase documents; we extract the figures for you.
  2. Verify your identity once (AML); it covers every LetsFile product for three years.
  3. Accept our agent invitation inside your HMRC Capital Gains Tax on UK property account (we walk you through it).
  4. A Chartered Accountant/Chartered Tax Advisor reviews, signs and files. You get email and SMS confirmation.

What you'll need

  • Completion statement from the sale
  • Purchase completion statement or contract (probate valuation if inherited)
  • Capital improvement costs, if any
  • Occupancy dates if the property was ever your home
  • A personal Government Gateway login for the agent authorisation

The 60-day return, answered

What is the 60-day CGT return?

When you sell UK residential property and Capital Gains Tax is due, HMRC requires a standalone return and payment within 60 days of completion. It is separate from your annual Self Assessment. Miss the deadline and penalties start at £100 and escalate, with interest on unpaid tax on top.

What exactly does the £199 Reviewed service include?

Everything: we extract the figures from your completion statement and purchase documents, apply every relief you are entitled to (Private Residence Relief, allowable costs, joint ownership, lettings relief where it applies), a Chartered Accountant/Chartered Tax Advisor reviews and signs the return, and we file it with HMRC as your agent. 90 days of HMRC enquiry support is included. The price is fixed: nothing is added at checkout.

What documents do I need?

The completion statement from your sale solicitor, your purchase completion statement or contract (or probate valuation for inherited property), receipts or summaries for capital improvements, and your occupancy history if the property was ever your home. Upload what you have; we tell you if anything is missing.

How fast will my return be filed?

Typically in 1 to 3 working days, guaranteed within 5 or your money back. The clock starts when we have your documents, your accepted HMRC agent authorisation and your cleared identity (AML) checks, and it pauses while we are waiting on you.

I am past the 60-day deadline. What now?

File as soon as possible: filing stops the daily penalty clock immediately. Our Emergency service (from £699, quoted per case by phone) prioritises your case, handles the penalty position and files within 3 working days. Call us, day or night.

We own the property jointly. Do we both need a return?

Each owner with tax to pay files their own return for their share of the gain, each with their own annual exempt amount and rate band. Tell us when you start and we handle the set together so the figures are consistent.

Do I need a Government Gateway account?

Yes. HMRC rules mean only you can authorise us as your agent, via a "Capital Gains Tax on UK property" account inside your personal Government Gateway login. We walk you through it with screenshots; allow a few minutes, longer if HMRC has to verify your identity from scratch.

What if I made a loss, or no tax is due?

UK residents only need the 60-day return when tax is due, so a loss usually means no return (though claiming the loss can be worth it for the future). Non-residents must report the disposal within 60 days regardless, even at a loss. If you are not sure of your residence status, settle that first; our free residence checker takes a minute.

Will the CGT I pay now be checked against my year-end position?

The 60-day return uses an estimate of your income for the year, so the in-year CGT can come out high. Your annual Self Assessment reconciles it, and HMRC refunds any overpayment. We can prepare the SA100 too, using the same documents.

What happens if HMRC asks questions later?

Reviewed includes 90 days of HMRC enquiry support after filing: we respond to HMRC as your agent. Beyond that window, our HMRC enquiry support service covers letters and compliance checks with a fixed quote before any work.

This page is general information, not tax advice. Your final liability depends on your facts; a Chartered Accountant/Chartered Tax Advisor confirms the figures before anything is submitted to HMRC.
