When Can You Claim a Refund?
Stamp duty refunds are available in several specific circumstances. The most common scenario involves the 5% additional property surcharge, but there are other situations where you might be entitled to reclaim SDLT you've already paid. Use our stamp duty calculator to check your liability. The 36-month refund rule is the most widely used mechanism for recovering the surcharge.
It's important to understand that SDLT refunds aren't automatic - you must actively claim them within the specified time limits. Here are the main situations where refunds apply:
1. Higher Rate Refund (Most Common)
If you bought a new home before selling your old one, you would have paid the 5% additional property surcharge. See our full stamp duty refund guide for details. You can claim this back if:
- You sell your previous main residence within 36 months of buying the new one
- The new property becomes your main residence
- You claim within the time limit (see below)
Refund Time Limits
England/NI: Claim within 12 months of selling old home, or 12 months from SDLT return date (whichever is later)
Scotland: Claim within 12 months of selling, but must sell within 18 months (shorter window)
Wales: Claim within 12 months of selling or return date
2. Overpayment Refund
You may be able to claim if you overpaid due to:
- Calculation error: Your solicitor or HMRC made a mistake in computing the SDLT owed
- Unclaimed relief: You were entitled to first-time buyer relief or other reliefs but didn't claim them
- Price reduction: The purchase price was reduced after completion (rare but possible)
- Multiple Dwellings Relief: You bought a property with an annex or granny flat that qualifies for MDR
- Uninhabitable property: You bought a derelict property that should have qualified for non-residential rates
- Became UK resident: You paid non-resident surcharge but subsequently became resident within the refund window
Time Limit for Overpayment Claims
You can claim a refund for overpayment errors within 4 years of the original filing date or the date payment was due (whichever is later). This is longer than the 12-month window for higher rate refunds.
How to Claim: Step-by-Step
The refund claim process is relatively straightforward, though you need to have all the correct information to hand. Here's how to do it:
Claiming Online (Recommended)
Access HMRC Online Services
Go to HMRC's Stamp Duty Land Tax online service. You'll need a Government Gateway user ID and password. If you don't have one, you can create it during the process.
Select "Amend a Return"
Choose the option to amend your original SDLT return. You'll need your unique transaction reference number (UTRN) from your original SDLT5 certificate.
Provide Sale Details
Enter the address and sale date of your previous property (for higher rate refunds), or details of the overpayment error (for other refund types).
Submit and Receive Confirmation
Review the refund amount, submit your claim, and you'll receive an online confirmation immediately. HMRC will process and pay the refund to the bank account registered with your original return.
Claiming By Post
If you prefer (or need) to claim by post:
- Download and complete form SDLT60 (for higher rate refunds) or SDLT17 (for amendments)
- Include supporting documents (completion statement, proof of sale, etc.)
- Provide bank details for the refund payment
- Send to: HMRC SDLT, BX9 1HD
Postal claims take significantly longer to process - typically 8-12 weeks compared to 4-6 weeks for online claims.
Using Your Solicitor
Your solicitor can claim the refund on your behalf, particularly useful if:
- They handled your original purchase and have all the details
- The refund involves complex calculations or multiple reliefs
- You're not comfortable navigating HMRC's online systems
Most solicitors will charge a fee for this service (typically £150-£300 plus VAT), but it can be worth it for larger refund amounts or complex situations.
Information You'll Need
- • SDLT unique transaction reference number (UTRN) - on your SDLT5
- • New property address and completion date
- • Previous property address and sale date (for higher rate refunds)
- • Sale price of previous property
- • Amount of refund being claimed
- • Bank details for payment (account name, sort code, account number)
- • National Insurance number
Time Limits for Refund Claims
Understanding time limits is crucial - miss the deadline and you lose your right to a refund, potentially costing thousands of pounds.
| Refund Type | Time Limit | Calculated From |
|---|---|---|
| Higher rate refund (England/NI) | 12 months | Whichever is later: sale date of old property OR SDLT filing date |
| Higher rate refund (Scotland LBTT) | 12 months | Sale date (old home must sell within 18 months) |
| Higher rate refund (Wales LTT) | 12 months | Sale date or filing date (whichever later) |
| Overpayment/error refund | 4 years | Filing date or effective date (whichever later) |
| Non-resident surcharge refund | 12 months | Date you became UK resident |
Important: Scotland's Shorter Window
In Scotland, you must sell your old home within 18 months to qualify for an LBTT refund (compared to 36 months in England and Wales). The 12-month claim period then runs from the sale date, giving you less total time than in the rest of the UK. Read more about replacement main residence rules.
How Long Does a Refund Take?
HMRC refund processing times vary depending on the claim method and complexity:
Online Claims
Typically processed within 4-6 weeks. The fastest method, with automatic validation and confirmation.
Postal Claims
Usually take 8-12 weeks to process. Manual processing means longer wait times.
What Affects Processing Time?
- Missing information: Incomplete claims are returned, restarting the clock
- Complex cases: Multiple reliefs or unusual circumstances require manual review
- Large amounts: Refunds over £10,000 may trigger additional verification
- HMRC workload: Tax year-end (January-April) sees longer processing times
Tracking Your Refund
If you claimed online, you can check the status through HMRC's online services using your Government Gateway account. For postal claims, you can call HMRC's SDLT helpline (0300 200 3510) after 8 weeks if you haven't received payment or correspondence.
Worked Example: Higher Rate Refund Calculation
Let's walk through a realistic scenario to see exactly how the refund works:
Scenario: Moving Home Before Selling
Initial Purchase (New Main Residence)
Property price: £400,000
Completion date: 15th January 2025
Previous property status: Still owned (not yet sold)
⚠️ 5% surcharge applies
| Band | Standard Rate | With 5% Surcharge | SDLT |
|---|---|---|---|
| £0-£250k | 0% | 5% | £12,500 |
| £250k-£400k | 5% | 10% | £15,000 |
| Total SDLT paid: | £27,500 | ||
Previous Property Sold
Sale date: 10th September 2025 (within 36 months ✓)
Sale price: £280,000
✓ Eligible for refund
| Recalculation | Amount |
|---|---|
| SDLT originally paid (with surcharge) | £27,500 |
| SDLT without surcharge (£400k main residence) | £10,000 |
| Refund due: | £17,500 |
Claim deadline: 10th September 2026 (12 months from sale)
Expected refund payment: 4-6 weeks after claim (if filed online)
In this example, the buyer saved £17,500 by claiming the refund after selling their old home. The refund represents the entire 5% surcharge that was applied to the £350,000 above the zero-rate band (£250,000 × 5% = £12,500, plus £150,000 × 5% = £7,500, minus the standard rates that would have applied).
Frequently Asked Questions About Stamp Duty Refunds
How long does an SDLT refund take?
Online claims typically take 4-6 weeks to process and pay, while postal claims can take 8-12 weeks or longer. Complex cases requiring manual review may take up to 16 weeks, especially during peak tax periods (January to April). You can check the status of online claims through HMRC's Government Gateway portal. The refund is paid directly to the bank account registered with your original SDLT return.
Can I claim stamp duty back on a second home?
Only if it was initially purchased as an additional property while you still owned your main residence, but then became your only property after selling the previous one. The key requirement is selling your old main residence within 36 months (England/Wales) or 18 months (Scotland) of buying the new property. If you genuinely bought it as an investment or holiday home with no intention of it becoming your main residence, the 5% surcharge is not refundable.
What evidence do I need for a stamp duty refund?
For higher rate refunds, you need proof of sale of your previous property (completion statement or sale contract), your SDLT5 certificate from the new purchase, and bank details for the refund payment. For overpayment refunds, you'll need documentation showing the error (original SDLT return, revised calculations, evidence of relief entitlement). HMRC may request additional evidence such as mortgage statements or utility bills proving the new property became your main residence.
Can my solicitor claim the refund for me?
Yes, your solicitor or conveyancer can file the refund claim on your behalf, and many buyers find this convenient, especially if the same solicitor handled the original purchase. They'll have all the necessary details and references on file. Most solicitors charge a fee for this service (typically £150-£400 plus VAT), which can be worthwhile for large refunds or complex cases. However, online claiming is straightforward enough for most people to do themselves and saves the fee.
Is there a deadline for stamp duty refund claims?
Yes, strict deadlines apply. For higher rate refunds, you must claim within 12 months of either selling your old property or filing your original SDLT return (whichever is later). In Scotland, you only have 12 months from the sale date, and the sale must happen within 18 months of buying the new property. For overpayment refunds, you have 4 years from the original filing date. Miss these deadlines and you permanently lose the right to claim, even for substantial amounts.
