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 list of refund types, see the stamp duty refund complete guide.
Higher Rate Refund Eligibility Checklist
For the time limit rules, see our dedicated page on the 36-month refund rule. If you are outside the deadline, see late refund claims for any remaining options.
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.
| Document | Why Needed | Where to Find It |
|---|---|---|
| UTRN (Unique Transaction Reference Number) | Identifies your original SDLT return | SDLT5 certificate from original purchase |
| Completion statement (new purchase) | Shows purchase price and completion date | From your conveyancer at purchase |
| Completion statement (old home sale) | Proves disposal within time limit | From your conveyancer at sale |
| Bank account details | HMRC pays refund by bank transfer | Your bank statements |
| Original SDLT return (form SDLT1) | Reference for the amendment | Your conveyancer or HMRC records |
| Evidence of SDLT paid | Confirms the original payment amount | Completion statement or bank records |
Find Your UTRN
The UTRN is a 14-character reference beginning with the year (e.g., 2023XXXXXXXXXX). It appears on your SDLT5 certificate, which HMRC sent to your conveyancer after filing your original SDLT return. If you cannot find it, contact your conveyancer. You cannot submit a refund claim without it.
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.
Online Claim (Recommended)
- Processing time: 4-6 weeks
- Instant submission confirmation
- Less risk of documents going missing
- Available 24/7 through HMRC website
- No postal delay risk
Postal Claim (Form SDLT60)
- !Processing time: 8-12 weeks
- !No automatic acknowledgement
- !Risk of postal delays or loss
- Option if online access unavailable
- Useful for complex claims with many attachments
Step-by-Step Claim Process
Follow these steps to submit your higher rate refund claim. For the amendment process (overpayments), see the SDLT return requirements page.
Confirm Your Eligibility and Deadline
Verify that your old home completed its sale within 36 months of your new purchase (or 18 months in Scotland), and that you are within 12 months of that sale completion. Check the 36-month rule for exact deadline calculations.
Gather All Required Documents
Collect your UTRN, completion statements for both properties, your bank details, and any other supporting evidence listed in the documents table above. Make copies of everything before submitting.
Calculate Your Refund Amount
Work out the refund you are claiming: the 5% surcharge on your full purchase price. See our refund calculation examples for worked examples. Use our second home calculator for a quick estimate.
Access the HMRC SDLT Service
Go to the HMRC online services and navigate to the SDLT section. You will need to log in with your Government Gateway credentials. If you do not have an account, register at HMRC's website before starting your claim.
Submit the Amendment
File an amendment to your original SDLT return. Enter your UTRN to locate the original return, then complete the amendment form showing the revised figures (standard rates instead of higher rates). Upload or reference your supporting documents.
Record Your Submission Reference
On submission, HMRC will provide a confirmation reference. Keep this reference safe. It is your proof that you submitted within the deadline, which matters if HMRC later queries the timing.
Wait for Processing
HMRC will review your claim and may contact you for additional information. Online claims typically take 4-6 weeks. If HMRC queries your claim, respond promptly with the requested evidence to avoid further delays.
Receive Your Refund
Once approved, HMRC will issue a repayment to your bank account. This typically arrives within a few working days of approval. If you have not heard within 8 weeks of an online submission, contact HMRC's SDLT helpline.
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.
What a solicitor will typically do
- Retrieve your original SDLT5 certificate and UTRN from their file
- Prepare the amendment to your SDLT return with correct figures
- Submit the claim through HMRC's agent services
- Monitor the claim and respond to HMRC queries
- Confirm receipt of the refund to you
Solicitor Fees for Refund Claims
Solicitors typically charge between £150 and £500 to handle a refund claim on your behalf. For large refunds (such as £20,000 or more), this is usually worthwhile for the convenience and expertise. For smaller refunds, submitting the claim yourself online may be more cost-effective.
Processing Times
HMRC's target processing times for stamp duty refunds vary depending on the complexity of the claim and the submission method.
| Claim Type | Online | Postal | Notes |
|---|---|---|---|
| Higher rate refund (straightforward) | 4-6 weeks | 8-12 weeks | Most common scenario |
| Non-resident refund | 6-10 weeks | 10-16 weeks | Requires residence evidence |
| Claims with HMRC queries | 3-6 months | 3-6 months | Depends on response speed |
| Disputed or complex claims | 6+ months | 6+ months | May require professional representation |
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 approves your claim
You will receive written confirmation of the refund amount and the payment will be made to your nominated bank account within a few working days of approval. Keep the confirmation letter for your records.
If HMRC requests more information
HMRC may write to you requesting additional evidence. Respond as quickly as possible with the requested documentation. Delays in responding will extend the processing time. Any evidence you send should be clearly labelled with your UTRN.
If HMRC rejects your claim
You have the right to appeal a rejected claim. See our guide on refund rejection appeals for the full process, including internal reviews and tribunal appeals.
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.
Common Mistakes That Delay Claims
Wrong or Missing UTRN
The UTRN must exactly match the one on your original SDLT5 certificate. Even a single character wrong will cause HMRC to reject or delay the claim.
Completion Date Errors
Using exchange dates instead of completion dates is a frequent error. HMRC checks both dates against its own records. Ensure both completion statements show the actual completion dates.
Claiming for the Wrong Property
Ensure the property you sold matches the one identified as your previous main residence. HMRC may query if the sold property address does not appear in its records as your main residence.
Missing Supporting Evidence
Submitting a claim without completion statements leads to automatic requests for more information, adding weeks to the process. Include all supporting evidence from the start.
Claiming After the 12-Month Deadline
The 12-month deadline from sale completion is as strictly enforced as the 36-month deadline. See late refund claims if you have missed this window.

Frequently Asked Questions
Can I submit the claim myself or do I need a solicitor?
You can submit the claim yourself through HMRC's online service. A solicitor is not required. However, if the claim is complex or you are uncomfortable with the process, a conveyancer or tax adviser can submit on your behalf for a fee. For straightforward cases, self-submission is entirely workable if you have all the documents.
What if I cannot find my SDLT5 certificate?
Contact the conveyancer who handled your original purchase. They are required to keep a copy of the SDLT5 certificate in their file. Alternatively, contact HMRC directly with your property address, completion date, and personal details to request the UTRN. This can add a few weeks to the process, so start early.
How will HMRC pay the refund?
HMRC pays stamp duty refunds by bank transfer to the account you specify in your claim. Ensure the account details are accurate. HMRC does not pay by cheque for online claims. If the account details are wrong, you will need to contact HMRC to redirect the payment, which adds time.
What if my claim is rejected? Can I appeal?
Yes. If HMRC rejects your claim, you have the right to request an internal review and, if that fails, to appeal to the First-tier Tax Tribunal. See our dedicated page on refund rejection appeals for the full process and what evidence to gather.
