Are you owed a Stamp Duty refund?

Stamp Duty Land Tax is overpaid far more often than buyers realise. When a property was uninhabitable, mixed-use, or contained more than one dwelling, a lower rate or relief usually applied — but many solicitors default to standard residential rates. If that happened to you, HMRC may owe you a refund of several thousand pounds, and you can typically claim up to four years after completion.

Frequently asked

How do I know if I overpaid Stamp Duty?

Common overpayments happen when a property was uninhabitable at purchase, was mixed residential/commercial use, or included more than one dwelling — but the solicitor applied standard residential SDLT rates. If any of these apply, you may be owed a refund.

How far back can I claim an SDLT refund?

Overpayment relief claims to HMRC can generally be made up to around four years after the effective date of the transaction. After that the window usually closes.

How much could I get back?

It depends on the purchase price and the relief that applied, but SDLT overpayments are frequently in the thousands of pounds. Our check estimates your specific refund before you commit.
