Helping UK Homeowners Reclaim Overpaid Stamp Duty

StampDutyBack connects homeowners with specialist solicitors and provides free tools to identify potential SDLT overpayments.

Why StampDutyBack Exists

Stamp duty overpayments are far more common than most people realise. HMRC estimates thousands of UK homeowners pay too much SDLT every year — through misclassified property types, overlooked reliefs, or errors made during conveyancing.

Recovering an overpayment has historically required knowing the right specialist and navigating a complex HMRC amendment process. Most homeowners simply don't know they can claim, or don't know where to start.

StampDutyBack was built to change that. We provide free calculators, guides, and tools so any homeowner can quickly understand whether they may have overpaid — and a clear, simple path to do something about it.

How StampDutyBack Works

Check Your Eligibility

Use our free Refund Estimator to get an instant estimate of whether you may have overpaid, based on your purchase price, property type, and circumstances.

Choose Your Path

Either connect with a vetted stamp duty specialist who handles the claim on your behalf, or use our DIY Claim Pack to submit the HMRC amendment yourself for £19.99.

Reclaim What You’re Owed

Successful claims result in a direct HMRC repayment, typically within 15–20 working days of submission. You have up to 4 years from the date of purchase to make a claim.

Who We Help

StampDutyBack is designed for UK homeowners who have purchased property in England or Northern Ireland within the last 4 years. Common situations we help with include:

Second home buyers — Who paid the 3% surcharge and later sold their previous main residence within 3 years.

New build purchasers — Where carpets, curtains or fixtures were included in the purchase price and not separated out for SDLT purposes.

Buy-to-let investors — Particularly where multiple dwellings were purchased in a single transaction.

Buyers of uninhabitable property — Where the property lacked a working kitchen or bathroom at the point of completion.

Mixed-use property buyers — Where a property with commercial elements was taxed at residential rates.

Our Specialist Network

We work with a curated panel of UK stamp duty specialists — experienced tax advisers and solicitors who focus exclusively on SDLT reclaims. When you submit a Get Help enquiry, your details are passed to a specialist who will review your case and contact you directly.

There is no upfront cost for the Get Help service. Specialists typically work on a contingency basis, taking a percentage of any successful refund only. You pay nothing if no refund is recovered.

For smaller claims — typically where the potential refund is under £500 — the DIY Claim Pack may be more economical, as specialist fees on smaller amounts can reduce the net recovery significantly.

Important Information

StampDutyBack is an online information and referral platform. We are not a law firm, tax adviser, or regulated financial services provider. The tools and calculators on this site are provided for informational purposes only and do not constitute tax or legal advice. Eligibility for a stamp duty refund depends on the specific facts of each transaction. We recommend seeking advice from a qualified specialist before submitting any claim to HMRC. Stamp duty rules apply to England and Northern Ireland only; different rules apply in Scotland (LBTT) and Wales (LTT).
