Stamp Duty Refund Guide
How to claim back overpaid stamp duty from HMRC.
Key Takeaways
- Scotland has a much shorter deadline. You must sell your old home within 18 months vs 36 months in England, Wales, and Northern Ireland
- The 12-month claim deadline is strictly enforced. HMRC rejects claims even one day late, so set calendar reminders when you sell
- Non-resident refunds require proving 183+ days UK presence within 2 years of purchase. Keep flight records, utility bills, and employment documentation
- Uninhabitable property claims are heavily scrutinized. You need structural surveys, building control notices, and photographic evidence from purchase date
- Online refund claims process faster (4-6 weeks) than postal claims and provide instant confirmation. Always use HMRC online service when possible
- You can claim up to £20,000 back on a £400k purchase if you paid the 5% surcharge then sold your old home within the time limit
- Refund amounts are the difference between rates with and without surcharge: a £600k property refund is £30,000 (£50k paid minus £20k standard)
- The two-year deed of variation window allows redirecting inherited property without SDLT. Commonly used for IHT planning after death

Types of SDLT Refund
You may be able to claim a stamp duty refund in several situations. Calculate your potential refund using our stamp duty calculator:
- Higher rate refund: Sold previous main home after paying 5% surcharge on new purchase
- Non-resident refund: Became UK resident after paying 2% non-resident surcharge
- Uninhabitable property: Property was genuinely uninhabitable at purchase, may qualify for non-residential rates
- Overpayment: Calculation errors, missed reliefs, or price reductions
- Special circumstances: Divorce, defective title, or compulsory purchase
Higher Rate Refund: Full Guide
The most common refund claim. If you bought a new home while still owning your previous main residence, you paid the 5% additional property surcharge. You can reclaim this if you sell your old home within the time limit under the replacement main residence rules. See second home surcharge details.
Time Limits by Region
| Region | Sell Within | Claim Within |
|---|---|---|
| England/NI | 36 months | 12 months of sale |
| Scotland | 18 months | 12 months of sale |
| Wales | 36 months | 12 months of sale |
Eligibility Criteria
To qualify for a higher rate refund, you must:
- Have paid the 5% surcharge on your new purchase
- Sell your previous main residence within 36 months of buying the new one (18 months in Scotland)
- Claim the refund within 12 months of selling your old home OR 12 months of filing your SDLT return (whichever is later)
- Intended the new property to be your main residence at the time of purchase
Important: Claim Deadline
You must submit your refund claim within 12 months of selling your old property. HMRC will not accept late claims, even by a single day. Set a reminder to ensure you don't miss this deadline.
Non-Resident Refund
If you were a non-UK resident when you purchased a property and paid the 2% non-resident surcharge, you can claim a refund if you become a UK resident within 2 years of purchase.
How to Qualify as UK Resident
To be considered a UK resident for this purpose, you must spend at least 183 days in the UK in a 12-month period starting from the date of purchase. HMRC will check:
- Physical presence in the UK for 183+ days
- Days counted include arrival and departure days
- Must occur within 2 years of the property purchase date
You must claim the refund within 2 years of becoming UK resident. Keep records of your UK presence (flight tickets, hotel bookings, utility bills, etc.) as HMRC may request evidence.
Uninhabitable Property Claims
If a property was genuinely uninhabitable at the date of purchase, it may qualify for non-residential rates (0% up to £150k, 2% to £250k, 5% above £250k) instead of residential rates. This can result in significant savings.
What Counts as Uninhabitable?
HMRC defines uninhabitable as a property that:
- Cannot be lived in due to structural issues (no roof, unsafe floors, condemned by building control)
- Lacks essential facilities (no water, electricity, heating, or sanitation)
- Has been officially declared uninhabitable by local authorities
- Requires major reconstruction before it can be occupied
Evidence Required
HMRC scrutinizes uninhabitable property claims closely. You will need strong evidence:
- Structural survey reports from qualified surveyors
- Building control notices or prohibition orders
- Photographs showing the state of the property at purchase
- Evidence that utilities were disconnected or non-functional
- Quotes for necessary works to make it habitable
Properties that are merely run-down, dated, or in need of cosmetic work do not qualify. The property must be genuinely uninhabitable, not just uninhabitable to you personally.
2. Overpayment Refunds
You can claim a refund if you overpaid due to:
- Calculation errors
- Missing first-time buyer relief
- Multiple Dwellings Relief not applied
- Purchase price reduction after completion
- Contract rescinded or not completed
3. Special Circumstances
- Divorce/separation: If you transfer property as part of a settlement
- Defective title: If purchase is unwound due to title issues
- Compulsory purchase: If property is later compulsorily purchased

Worked Example: Calculating Your Refund Amount
Scenario
Sarah bought a new house for £400,000 in January 2024. She still owned her previous home, so she paid the 5% additional property surcharge. She sold her old home in December 2025 (within 36 months). What refund can she claim?
Step 1: Calculate what Sarah paid
Step 2: Calculate what she would have paid without surcharge
Step 3: Calculate refund
Sarah must claim this refund within 12 months of selling her old home (by December 2026).

Frequently Asked Questions About Stamp Duty Refunds
How do I claim stamp duty back?
To claim stamp duty back, you need your SDLT unique transaction reference (UTRN) from your original SDLT5 certificate, evidence of the qualifying event (such as completion statement from selling your old home), and your bank details. You can claim online through the HMRC SDLT service (fastest) or by post using form SDLT60. For higher rate refunds, you must claim within 12 months of selling your previous home or 12 months of filing your SDLT return, whichever is later. Your solicitor can also submit the claim on your behalf, though they may charge a fee for this service. Review SDLT return filing requirements.
How long does a stamp duty refund take?
Straightforward stamp duty refund claims typically take 4-6 weeks to process from the date HMRC receives all required information. Non-resident refund claims can take 8-12 weeks. Claims that HMRC queries or disputes (such as uninhabitable property claims) can take 3-6 months or longer. Online claims are usually processed faster than postal claims. HMRC may contact you for additional information, which will extend the processing time. Once approved, the refund is paid directly to your bank account within a few working days. You cannot speed up the process, but ensuring your claim is complete and accurate helps avoid delays.
Can I claim stamp duty back on a second home I've sold?
Yes, if you paid the 5% additional property surcharge when buying a new main residence because you still owned your previous home, you can claim this back once you sell the old property. You must sell within 36 months of buying the new home (18 months in Scotland) and claim within 12 months of the sale. The property you sold must have been your previous main residence. You cannot claim refunds on the sale of investment properties or genuine second homes. The refund amount is the difference between what you paid with the surcharge and what you would have paid without it.
What evidence do I need for a stamp duty refund?
For a higher rate refund, you need your SDLT unique transaction reference (UTRN), completion statement from selling your previous home showing the sale date, and bank details. For non-resident refunds, you need evidence of UK residence such as passport stamps, flight records, utility bills, and employment records proving 183+ days in the UK within a 12-month period. For uninhabitable property claims, you need structural survey reports, building control notices, photographs of the property at purchase, and evidence of disconnected utilities. Keep all documents organized and make copies before submitting, as HMRC may request additional verification.
Is there a time limit for stamp duty refunds?
Yes. For higher rate refunds, you must claim within 12 months of selling your previous home OR 12 months of filing your SDLT return, whichever is later. You must also have sold the property within 36 months of buying your new home (18 months in Scotland). For non-resident refunds, you must claim within 2 years of becoming UK resident. For overpayment refunds, you generally have 4 years from the filing date or 12 months from when you became aware of the overpayment, whichever is later. HMRC strictly enforces these deadlines. Late claims are almost never accepted, even by a single day. Set calendar reminders to ensure you claim on time.
