Introduction
First-time buyer relief is one of the most frequently claimed SDLT reliefs — and one of the most frequently queried by clients. As a conveyancing solicitor, you need to know the eligibility rules inside out, because getting it wrong means your client either overpays or faces a penalty for underpaying.
This guide covers everything: the current thresholds, how to calculate the relief, what happens with joint purchasers of mixed first-time buyer status, and the common pitfalls that catch firms out.

Current First-Time Buyer SDLT Rates (2026/27)
First-time buyer relief applies to residential properties purchased for £500,000 or less:
| Band | Rate |
|---|---|
| £0 – £300,000 | 0% |
| £300,001 – £500,000 | 5% |
If the purchase price exceeds £500,000, the relief is not available and standard residential rates apply to the entire purchase price. There is no tapering — it is a hard cut-off.
Worked Examples
Example 1: Property at £280,000
The entire amount falls within the 0% band. SDLT due: £0.
Example 2: Property at £425,000
- First £300,000 at 0% = £0
- Remaining £125,000 at 5% = £6,250
- Total SDLT: £6,250
Compare this to standard rates, where the same property would attract £8,750 in SDLT — a saving of £2,500.
Example 3: Property at £500,000
- First £300,000 at 0% = £0
- Remaining £200,000 at 5% = £10,000
- Total SDLT: £10,000
Example 4: Property at £500,001
Relief is not available. Standard rates apply to the full amount:
- First £125,000 at 0% = £0
- Next £125,000 at 2% = £2,500
- Remaining £250,001 at 5% = £12,500.05
- Total SDLT: £15,000 (rounded)
The £1 difference in purchase price costs the buyer an extra £5,000 in tax. This is a critical point to advise clients on.
Eligibility Criteria
A purchaser qualifies as a first-time buyer if they:
- Have never owned a freehold or leasehold interest in residential property — anywhere in the world, not just the UK
- Are purchasing a single dwelling — the relief does not apply to purchases of two or more dwellings in a single transaction
- Intend to occupy the property as their only or main residence
What Counts as "Owning" Property?
The test is whether the purchaser has ever held a major interest (freehold or leasehold with more than 21 years remaining at grant) in a dwelling. This includes:
- Properties owned abroad
- Inherited properties (even if subsequently sold)
- Properties held through a trust where the purchaser was a beneficiary with an interest in possession
- Buy-to-let properties previously owned
It does not include:
- Properties held only as a bare trustee (where the purchaser had no beneficial interest)
- Commercial property
- Land without a dwelling
Joint Purchasers: The Mixed-Status Problem
This is where conveyancers most frequently encounter complications.
Rule: ALL purchasers must be first-time buyers for the relief to apply.
If a first-time buyer purchases jointly with someone who has previously owned property, the relief is lost entirely. Standard rates apply to the whole purchase.
Common Scenarios
Scenario 1: Two first-time buyers purchasing together Relief applies. Both qualify.
Scenario 2: First-time buyer purchasing with a parent who owns their home Relief does not apply. The parent is not a first-time buyer, so the entire transaction is taxed at standard rates.
Scenario 3: First-time buyer purchasing with a partner who previously owned (but sold) Relief does not apply. The partner has previously owned residential property, even though they do not currently own any.
Advising Clients
When a joint purchase involves a non-first-time buyer, you should advise the client on:
- Whether it is practical for the first-time buyer to purchase alone (subject to mortgage affordability)
- The financial impact — calculate the difference between first-time buyer rates and standard rates
- Whether the additional property surcharge also applies (if the non-first-time buyer still owns another property)
Interaction with Other Surcharges
First-time buyer relief cannot be combined with:
- Additional property surcharge (5%) — if the purchaser owns another dwelling, they are by definition not a first-time buyer
- Non-resident surcharge (2%) — a first-time buyer who is non-UK resident pays the non-resident surcharge on top of first-time buyer rates (this combination is possible and catches some firms out)
First-Time Buyer + Non-Resident
A non-resident first-time buyer purchasing at £400,000:
- First £300,000 at 0% + 2% = £6,000
- Next £100,000 at 5% + 2% = £7,000
- Total SDLT: £13,000
The 2% non-resident surcharge applies to every band, including the 0% first-time buyer band.
Common Pitfalls for Conveyancers
1. Client Self-Assessment of First-Time Buyer Status
Never take the client's word for it without proper enquiry. Ask specifically:
- Have you ever owned any residential property, anywhere in the world?
- Have you inherited any property, even if you sold it immediately?
- Are you or have you been a beneficiary of a trust that held residential property?
2. The £500,000 Cliff Edge
Clients need to understand that pricing a property at £500,001 or above eliminates the relief entirely. If a property is marketed at or near £500,000, the tax implications of the final agreed price are significant.
3. Linked Transactions
If a first-time buyer purchases a property as part of a linked transaction (for example, buying a house and a garage in separate transactions from the same vendor), the total consideration across all linked transactions must not exceed £500,000 for the relief to apply.
4. Shared Ownership
First-time buyer relief is available on the initial share of a shared ownership property, provided:
- The market value of the whole property does not exceed £500,000
- The purchaser elects to pay SDLT on the initial share only (not the market value)
5. Claiming Retrospectively
If a return was filed without claiming first-time buyer relief and the purchaser was eligible, an amended return can be submitted within 12 months of the filing date to claim a refund.
Filing the Return
When claiming first-time buyer relief on the SDLT return:
- Relief code: Use the appropriate HMRC relief code on the SDLT1
- All purchasers: You must confirm that every purchaser qualifies
- Declaration: The purchaser signs a declaration confirming first-time buyer status
If HMRC later determines that the relief was incorrectly claimed, the purchaser faces:
- The full SDLT liability at standard rates
- Interest from the original effective date
- Potential penalties for careless or deliberate inaccuracy
Key Takeaways for Conveyancers
- Always verify — ask the right questions about worldwide property ownership history
- Watch the cliff edge — advise clients about the £500,000 threshold
- Joint purchasers — one non-first-time buyer disqualifies the whole transaction
- Non-resident interaction — the 2% surcharge still applies to first-time buyers
- Keep records — document your first-time buyer enquiries in the file
