Stamp Duty Refund: Complete Step-by-Step Guide to Claiming Back from HMRC

Can I Claim a Stamp Duty Refund?

Stamp duty refunds are available in several specific circumstances. The most common is the 5% additional property surcharge refund when you replace your main residence. Other refund types include overpayment refunds (calculation errors, missed reliefs), non-resident surcharge refunds (became UK resident), and uninhabitable property refunds.

Refunds are not automatic. You must actively claim them within the time limits below, or the right to a refund expires.

The Five Refund Types

• Higher rate refund (most common): Sold previous main home within 36 months of buying the new one. See the 36-month refund rule.
• Overpayment refund: Calculation error, missed first-time buyer relief, or price reduction after completion. 4-year claim window.
• Non-resident surcharge refund: Paid the 2% non-resident surcharge then became UK resident within the qualifying window.
• Uninhabitable property refund: Property was genuinely uninhabitable at purchase and should have qualified for non-residential rates.
• Multiple Dwellings Relief (historical): Property contained an annex or granny flat that qualified for MDR before June 2024 abolition.

Each type has different eligibility rules, time limits and evidence requirements, covered in detail in the next section. To check the exact amount you could claim back, use the stamp duty refund calculator.

Refund Types: Detailed Eligibility & Time Limits

The five refund types have very different rules and deadlines. Below is the detailed eligibility for each, with cross-links to the dedicated guides where the topic gets deeper treatment.

1. Higher-Rate Refund (most common)

If you bought a new home while still owning your previous main residence, you paid the 5% additional property surcharge (or 8% ADS in Scotland, higher-band rates in Wales). You can reclaim that surcharge if you sell the old home within 36 months. The deadline math is strict, and missing the 36-month window or the 12-month claim filing deadline means the right to refund expires. See the dedicated 36-month refund rule guide for the timeline mechanics and the replacement main residence rules for the underlying SDLT relief.

2. Non-Resident Surcharge Refund

If you were a non-UK resident when you bought a property and paid the 2% non-resident surcharge, you can reclaim it if you become UK resident within 2 years of purchase. To qualify as UK resident for this purpose, you must spend at least 183 days in the UK in a 12-month period starting from the purchase date. HMRC counts arrival and departure days. The claim must be made within 2 years of becoming UK resident; keep flight records, hotel bookings and utility bills as evidence.

3. Uninhabitable Property Refund

If a property was genuinely uninhabitable at the date of purchase, it may qualify for non-residential SDLT rates (0% up to £150k; 2% to £250k; 5% above £250k) instead of residential rates, often a substantial saving. HMRC's test is strict: the property must lack essential facilities (no water/electricity/heating/sanitation), have structural issues that prevent occupation (no roof, unsafe floors, condemned by building control), be officially declared uninhabitable by the local authority, or require major reconstruction before occupation. Cosmetic disrepair (peeling paint, dated kitchen) is not enough. Evidence required: structural survey, building-control notice, contractor reports.

4. Overpayment Refund

You can claim a refund where you overpaid SDLT due to: calculation errors; missed first-time buyer relief; Multiple Dwellings Relief not applied (transactions before 1 June 2024); a purchase price reduction agreed after completion; or a contract rescinded or never completed. Overpayment claims fall under SDLT overpayment relief and have a 4-year amendment window from the SDLT filing date, substantially longer than the 12-month higher-rate window. See late refund claims for the rules around claiming after deadlines have lapsed.

5. Special Circumstances

• Divorce or separation: Property transfers as part of a court-ordered settlement are SDLT-exempt under FA 2003 Schedule 3 paragraph 3 (or 3A for civil partners). If SDLT was paid in error, a refund applies. See the divorce property transfer guide.
• Defective title: If the purchase is unwound due to title defects discovered after completion, SDLT becomes refundable.
• Compulsory purchase: If a property is later compulsorily purchased by a public authority, the original SDLT may be reclaimable under compulsory purchase relief.

Before You Start: Am I Eligible?

Before gathering documents and submitting a claim, confirm that you meet the eligibility criteria. The most common refund type is the higher rate refund for people who sold their previous main residence. For a full breakdown of all five refund types and their time limits, see refund types: detailed eligibility above.

The two deadlines that govern the higher-rate refund, and your options if you have missed one, are covered in refund deadlines and what if you miss them below.

Refund Deadlines and What If You Miss Them

Two separate deadlines govern the higher-rate refund, and they work differently. Both are conditions of entitlement set by statute (Schedule 4ZA Finance Act 2003), not penalty deadlines, so the “reasonable excuse” rules that can excuse a late filing penalty do not apply here. Miss either deadline and the right to the refund is lost, regardless of the reason.

If You Think You Have Missed the Deadline

Do not assume the refund is gone without checking two things first:

• Verify the exact dates. Get the completion statements for both properties. Off-by-one errors and using exchange dates instead of completion dates are common, and you may be inside the window after all.
• Check for a separate overpayment. If the SDLT was wrong for another reason (a calculation error, a missed first-time buyer relief, the wrong rate applied), overpayment relief may apply on its own timeline.

If a solicitor handled both your purchase and your later sale and failed to flag the refund, causing you to miss the deadline, the lost refund may be recoverable as a professional negligence claim against them rather than from HMRC. The stakes are usually tens of thousands of pounds, so specialist SDLT advice is worthwhile. Check the exact figure with the stamp duty refund calculator.

Documents You Will Need

Having all documents ready before you start your claim will significantly speed up processing. Missing information is the single most common cause of delayed or rejected claims.

Online vs Postal Claims

HMRC offers two methods for submitting a stamp duty refund claim: online through the HMRC SDLT service, or by post using form SDLT60. In almost all cases, online submission is faster, more reliable, and provides instant confirmation that HMRC received your claim.

Step-by-Step Claim Process

Follow these steps to submit your higher rate refund claim. For the amendment process (overpayments), see the SDLT return amendment guide.

What Your Solicitor Does

Many solicitors routinely handle stamp duty refund claims on behalf of their clients, particularly conveyancers who handled both the purchase and the subsequent sale. However, their involvement is not automatic and there is often an additional charge for this service.

Processing Times

HMRC's target processing times for stamp duty refunds vary depending on the complexity of the claim and the submission method.

What Happens After Submission

After you submit your claim, HMRC will review it to confirm you meet the eligibility criteria. In most straightforward cases, HMRC will process the claim and issue the refund without further contact.

If HMRC Rejects Your Claim: Review and Appeals

HMRC must give reasons for rejecting a refund claim. The most common are a missed deadline, HMRC not accepting that the property you sold was your main residence, insufficient evidence, or an administrative error such as a wrong UTRN. Read the rejection letter carefully: it sets out the reason and your appeal rights, including the deadline to request a review (usually 30 days).

Step 1: Ask for an internal review (free)

An internal review is carried out by an HMRC officer who was not involved in the original decision. It is free and you should always use it before going to a tribunal. Request it in writing within 30 days of the rejection, quote your UTRN and case reference, set out why the decision is wrong, and attach supporting evidence. HMRC normally completes the review within 45 days and can uphold, vary, or cancel the original decision.

Step 2: Appeal to the First-tier Tax Tribunal

If the review upholds the rejection, you have 30 days to appeal to the First-tier Tax Tribunal (Tax Chamber), an independent court that is not part of HMRC. Most SDLT refund cases fall in the basic track, which usually carries no filing fee and little costs risk. The Tribunal can decide factual disputes (such as dates or main residence status) but it cannot override a clear statutory deadline.

How to Track Your Claim

HMRC does not provide an online tracking system for stamp duty refund claims in the same way as self-assessment refunds. You can check the status by:

• Logging into your HMRC online account and checking the SDLT section
• Contacting HMRC's SDLT helpline (0300 200 3510) and quoting your UTRN and submission reference
• Asking your solicitor or agent if they submitted on your behalf

If 8 weeks have passed since your online submission and you have received no contact from HMRC, it is reasonable to follow up by phone. Allow longer if you submitted by post.
