Don’t Miss The 60-Day Deadline: HMRC CGT Property Reporting Reminder

Sold a UK Residential Property? HMRC Are Reminding Taxpayers of The 60-Day CGT Deadline

If you’ve recently sold, or are about to sell, a UK residential property, this important update from HMRC applies to you.

In a new compliance initiative, HMRC are proactively contacting taxpayers to remind them of the strict legal requirement to report and pay Capital Gains Tax (CGT) on UK residential property disposals within 60 days of completion.

Using Land Registry and property transaction data, HMRC will identify individuals who may need to file a 60-day CGT return and will send a targeted reminder letter before the deadline expires. The letter will name the property involved and include guidance on when a return is required.

If you receive an HMRC letter but believe a 60-day return is not needed in your case, you should contact HMRC directly using the details provided to explain your position.

Who Does The 60-Day Rule Apply To?

• UK residents disposing of UK residential property where a capital gain arises

• Non-UK residents selling UK residential property

This rule is separate from Self-Assessment. Even if you complete an annual tax return, you must still report the property disposal and pay any CGT due within 60 days of completion. The gain must also be included in your annual Self-Assessment return.

Don’t Fall Foul of Late Filing

Missing the 60-day deadline can lead to:

• Automatic interest charges on late-paid CGT

• Potential financial penalties for late submission

• Unnecessary compliance checks from HMRC

  
  

While HMRC says only a targeted number of taxpayers will receive these reminder letters, they will be issued regularly as new property sales are recorded. All property sellers and their advisers should stay aware of this fast-approaching deadline.

The 60‑day window passes quickly. Whether you are selling:

• A second home

• An inherited or previously let residential property

Early preparation helps avoid unnecessary penalties, interest and last‑minute errors.
