How to Claim First-Time Buyer Stamp Duty Relief
A practical, step-by-step guide to claiming first-time buyer relief correctly, from confirming eligibility to protecting your claim after completion.
Key Takeaways
- Tell your solicitor you are a first-time buyer at the instruction stage, not on completion day, so the SDLT1 form is filed correctly from the start
- Your solicitor submits the SDLT return to HMRC within 14 days of completion and pays the tax on your behalf. You never deal with HMRC directly
- HMRC can audit your FTB claim for 12 months after filing. Keep your completion statement, SDLT5 certificate, and any proof of no prior ownership
- Joint buyers both need FTB status. If one partner has ever owned property anywhere in the world, neither can claim the relief
- Buying above £500,000 by even £1 eliminates relief entirely. Standard rates apply to the full price, costing you up to £10,000 extra vs buying at £500,000

Step 1: Confirm Your Eligibility (2-Minute Check)
Before anything else, you need to be certain you qualify. HMRC defines first-time buyer status strictly, and a mistake at this stage can result in an unexpected tax bill months after you move in. Answer "yes" to all five questions below to confirm you are eligible. If any answer is "no", you cannot claim first-time buyer relief on this purchase.
Your 5-Point Eligibility Check
- 1
Have you never owned a residential property anywhere in the world?
This includes property inherited, gifted, held in trust, or owned abroad, even decades ago. If you have ever had legal ownership of any residential property, you do not qualify.
- 2
Is the property priced at £500,000 or below?
First-time buyer relief disappears entirely above £500,000. Even £500,001 means you pay standard rates on the full purchase price, not just the excess.
- 3
Will you be living in this property as your main residence?
FTB relief is for owner-occupiers only. If you intend to rent the property out immediately after purchase, you cannot claim it, and doing so would constitute a false declaration to HMRC.
- 4
Are you purchasing in England or Northern Ireland?
Scotland has a separate LBTT first-time buyer relief with a £175,000 threshold. Wales has no equivalent relief under Land Transaction Tax. This guide covers SDLT in England and Northern Ireland.
- 5
If buying jointly, have all co-buyers also never owned property?
Every person named on the purchase deed must be a first-time buyer. One partner having previously owned a property, even briefly, removes the relief for the entire transaction.
If you answered yes to all five, you are eligible. For complex situations, check the detailed FTB eligibility criteria, or for overseas ownership, trust arrangements, or shared ownership, read the full rules in our first-time buyer complete guide.
Step 2: Calculate Your Exact Savings
Understanding how much you save helps you budget accurately and assess whether a price negotiation could push you below a key threshold. Since April 2025, first-time buyer relief works as follows: 0% on the first £300,000, and 5% on the portion between £300,001 and £500,000. Standard rates start at 0% on the first £125,000, then 2% up to £250,000, then 5% above that.
| Property Price | Standard SDLT | FTB SDLT | Your Saving |
|---|---|---|---|
| £250,000 | £2,500 | £0 | £2,500 |
| £300,000 | £5,000 | £0 | £5,000 |
| £400,000 | £10,000 | £5,000 | £5,000 |
| £500,000 | £15,000 | £10,000 | £5,000 |
The £500,000 Cliff Edge
Notice that buying at exactly £500,000 as a first-time buyer costs £10,000 in SDLT. If you pay £500,001, just one pound more, you lose all FTB relief and pay standard rates on the full price: £15,000. That single extra pound costs you £5,000 in tax. If a seller is asking £505,000, it is worth negotiating hard to £500,000 or reconsidering the purchase.
These examples use round numbers. Your exact figure will depend on the agreed purchase price. Use our first-time buyer calculator to get your precise SDLT figure in seconds.
Step 3: Inform Your Solicitor Early
The single most important practical step is telling your solicitor you are a first-time buyer at the instruction stage, when you first instruct them to act on your behalf, typically once your offer is accepted. Do not wait until exchange or completion. Your solicitor needs this information early for two reasons: first, to give you an accurate cost breakdown that reflects FTB relief; and second, to ensure they prepare the SDLT1 return correctly from the outset.
The SDLT1 is the return form submitted to HMRC to declare and pay stamp duty. It includes specific fields for first-time buyer status that your solicitor must complete. If this information is missing or incorrect, HMRC may treat you as a standard buyer and calculate a higher tax liability. Correcting this after completion is possible but involves additional paperwork and potential delays.
What to Say to Your Solicitor
- "I am a first-time buyer and have never owned property anywhere in the world. Please ensure FTB relief is applied on the SDLT1 return."
- Confirm the same applies to any co-buyer, stating they are also a first-time buyer.
- Ask for a revised completion statement that reflects the FTB-reduced SDLT liability before you sign anything.
- Get the confirmation in writing (email is fine) so there is a clear record that you flagged your FTB status at instruction.
Reputable solicitors handle this routinely and will ask the right questions as part of their client onboarding. If yours does not ask, raise it yourself. Never rely on a verbal assurance that FTB relief "will be sorted out", as verbal promises are not enough if an error occurs on the SDLT return.
Step 4: Prepare Your Evidence
You do not need to submit proof of first-time buyer status to HMRC when your solicitor files the SDLT return. The return is a self-declaration. However, HMRC has a 12-month enquiry window during which it can investigate any SDLT return and request supporting documentation. If you cannot produce evidence when asked, HMRC may disallow the relief and issue a penalty notice.
Gather the following documents before completion and keep them together in a safe place for at least two years after completion:
Documents HMRC May Request
Government-Issued Photo ID
Passport or driving licence for each buyer. Your solicitor will already need this for anti-money laundering checks, so it should be straightforward to keep a copy.
Proof of Current Address History
Utility bills, bank statements, or tenancy agreements showing you have been renting or living with family, not paying a mortgage or owning a property, for the past several years.
Worldwide Property Disclosure Statement
A written statement (signed and dated) confirming you have never owned property in any country. If you have lived abroad, include a brief narrative covering those periods and confirming you rented rather than owned.
Inherited Property Evidence (if applicable)
If you were a beneficiary of an estate that included property, obtain a letter from the estate's solicitor confirming you did not inherit, or, if you did inherit and then sold, the dates of ownership. Note that inherited property, even if immediately sold, generally disqualifies FTB status.
Joint Buyer Evidence
If purchasing with a partner, gather the same documentation for each buyer. HMRC will want to confirm both parties were genuinely first-time buyers at the date of completion.
HMRC is particularly vigilant about overseas property and inherited property. If either applies to you, speak to a tax adviser before proceeding. The relief is worth up to £5,000 in tax savings, but a false claim can result in penalties, interest at 7.5% per annum on unpaid tax, and in serious cases, prosecution.
Step 5: What Happens on Completion Day
On completion day, the legal ownership of the property transfers to you. Behind the scenes, your solicitor manages the SDLT process entirely. You do not contact HMRC or make any payment directly to the tax authority. Here is exactly what happens:
- 1
Funds Transfer
Your solicitor receives the mortgage funds from your lender and your deposit. The SDLT amount has been included in the money you sent your solicitor in advance as part of your completion funds, listed on your completion statement.
- 2
SDLT1 Submission
Your solicitor submits the SDLT1 return to HMRC electronically. This form declares the property details, the purchase price, the buyer's first-time buyer status, and the SDLT payable. The FTB relief reduces the amount due automatically based on the price.
- 3
14-Day Deadline
HMRC requires the SDLT return to be filed and any tax paid within 14 days of completion. Your solicitor handles this as a matter of course. If the deadline is missed, HMRC charges automatic late filing penalties starting at £100, even if no tax is owed.
- 4
SDLT5 Certificate Issued
Once HMRC processes the return, it issues an SDLT5 certificate confirming the tax has been paid (or that no tax was due). Your solicitor receives this and forwards it to you. Keep it, as it is part of your property's legal documentation and you will need it if you sell in the future.
- 5
Land Registry Registration
Your solicitor uses the SDLT5 certificate to register your ownership at the Land Registry. Without it, the registration cannot proceed. This is another reason the 14-day deadline matters, as delays in SDLT filing hold up formal registration.
Your only action on completion day itself is to check your completion statement beforehand to confirm the FTB-reduced SDLT figure appears correctly. If you spot standard rates instead of FTB rates, raise it with your solicitor immediately, before funds transfer.
Step 6: After Completion: Protect Your Claim
Most buyers move in and assume the SDLT process is finished. In legal terms it is, but HMRC retains the right to enquire into any SDLT return for 12 months from the date of filing. During this window, HMRC can request evidence to verify that the FTB relief was correctly claimed. Understanding what to keep and what an enquiry looks like will help you respond calmly if one arises.
Records to Keep for at Least 2 Years
- Completion statement from your solicitor showing the FTB-reduced SDLT figure
- SDLT5 certificate issued by HMRC confirming the return was accepted
- Email correspondence with your solicitor confirming you declared FTB status at instruction
- Previous rental tenancy agreements or address history evidence showing you were renting before purchase
- Your worldwide property disclosure statement (the written confirmation you prepared in Step 4)
If HMRC opens an enquiry, it will typically write to your solicitor with a list of questions or document requests. Your solicitor handles the response on your behalf. HMRC enquiries are not uncommon and do not automatically imply wrongdoing; they are routine checks, especially where significant relief has been claimed. The key is having clean documentation to close the enquiry quickly.
If HMRC finds that the relief was incorrectly claimed, for example because one buyer had forgotten about a small overseas property, it will issue a determination for the unpaid tax plus interest at 7.5% per annum from the completion date. There is a formal appeal process if you believe the determination is wrong.
7 Mistakes That Lose First-Time Buyer Relief
These are the most common reasons buyers lose FTB relief, often discovered only after completion, when correcting the error is expensive and stressful.
1. Not Disclosing Inherited Property
Inheriting residential property, even briefly, even if you immediately sold it, typically disqualifies you from FTB status. Many buyers do not realise that inherited property counts as having owned property. HMRC cross-references land registry records and probate data, so omissions are regularly caught during enquiries.
2. Joint Purchase with a Non-First-Time Buyer
If your partner, spouse, family member, or friend buying jointly with you has ever owned property, FTB relief is lost for the entire transaction. There is no partial relief, no matter how small that person's share of the purchase. See our complete FTB guide for alternatives if this applies to you.
3. Buying Above £500,000 by £1
The £500,000 threshold is absolute. A property agreed at £500,001 means you pay standard rates on the full price: £15,000 rather than the £10,000 you would pay as an FTB at £500,000. Always scrutinise prices near this boundary and negotiate accordingly.
4. Buying a Property You Do Not Intend to Live In
First-time buyer relief is conditional on the property being your main residence. If you purchase a property and immediately let it out, even while living elsewhere temporarily, you are not entitled to the relief. HMRC has successfully challenged claims in cases where buyers moved in briefly and then rented the property.
5. Forgetting Foreign Property Ownership
Property owned abroad counts fully for FTB purposes. This catches buyers who owned property in their home country before emigrating to the UK, or who purchased a holiday home overseas years ago. HMRC's definition is deliberately global; there are no exceptions for foreign property.
6. Missing the 14-Day Filing Deadline
The SDLT1 return must be submitted and any tax paid within 14 days of completion. Late filing triggers automatic penalties from HMRC, starting at £100 and escalating for prolonged delays, even if no tax is owed. Your solicitor manages this, but ensure you provide all completion funds and signed documentation on time.
7. Relying on Verbal Solicitor Instructions
Telling your solicitor verbally that you are a first-time buyer is not enough if it is not reflected in the SDLT1. Always confirm your FTB status in writing and check your completion statement to verify the FTB-reduced SDLT figure before funds transfer. If the statement shows the wrong amount, query it immediately.

Frequently Asked Questions
These FAQs focus on the procedural aspects of claiming FTB relief. For eligibility questions (what counts as property ownership, overseas property, inherited property, trust arrangements), see our complete first-time buyer eligibility guide. If only one buyer qualifies, check whether partial relief applies.
When should I tell my solicitor I am a first-time buyer?
Tell them at the instruction stage, when you first engage them after your offer is accepted. This is typically four to twelve weeks before completion, depending on the chain. Instructing your solicitor early gives them time to factor FTB relief into your completion statement accurately, ensures the SDLT1 form is prepared correctly, and creates a clear written record that you declared your FTB status from the outset. Never assume your solicitor will ask. Raise it proactively in your first email or call.
What happens if HMRC audits my FTB claim?
HMRC has a 12-month enquiry window from the date the SDLT1 return is filed. If HMRC selects your return for review, it will write to your solicitor, not directly to you, requesting evidence to support the FTB declaration. Common requests include proof of address history (showing you were renting), ID documents, and a statement confirming no prior property ownership worldwide. Your solicitor responds on your behalf. If you have kept the documents described in Step 4, most enquiries close within a few weeks. If HMRC is not satisfied with the evidence, it may disallow the relief and issue a determination for additional tax plus interest. You have the right to appeal any determination within 30 days.
Can I claim FTB relief after completion if my solicitor forgot to apply it?
Yes. If your solicitor filed the SDLT1 return without applying FTB relief, and you were genuinely eligible, you can amend the return and claim a refund. HMRC allows amendments to SDLT returns within 12 months of the filing deadline (i.e., within approximately 12 months of completion). Your solicitor files an amended return correcting the FTB status, and HMRC processes the refund, typically within 15 working days. You will need to provide the same evidence you would for a standard claim. If more than 12 months have passed, the amendment window is closed and the overpaid SDLT is generally not refundable through the standard process, though a formal overpayment relief claim to HMRC may still be possible in limited circumstances.
What documents should I keep after claiming FTB relief?
Keep the following for at least two years after completion: your completion statement showing the FTB-reduced SDLT figure; the SDLT5 certificate issued by HMRC after the return was processed; all email correspondence with your solicitor in which you declared your FTB status; previous rental tenancy agreements or address history documents covering the period before your purchase; your signed worldwide property disclosure statement; and, for joint purchases, the same documentation for each co-buyer. Store physical copies and digital backups. If HMRC raises an enquiry and you cannot locate these documents, your solicitor will need to reconstruct the file, which is time-consuming and sometimes incomplete.
