The rates-and-bands reference for the relief (the 0% / 5% / £500,000-cap rate table, the 1 April 2025 threshold reversion, the cliff-edge mechanics) is on our applicable SDLT rates for first-time buyers companion page. This page covers the eligibility side: the statutory definition, the joint-purchase rule, the intention-to-occupy test, the single-dwelling limitation, the shared-ownership election under paragraphs 6A to 6D, and the F(No.2)A 2024 section 8 bare-trust amendment.
The Schedule 6ZA paragraph 6 definition of "first-time buyer"
The relief lives in FA 2003 section 57B and Schedule 6ZA. The definition of "first-time buyer" is in Schedule 6ZA paragraph 6. The substance: an individual who has not previously been a purchaser in relation to a land transaction the main subject-matter of which was a major interest in a dwelling situated anywhere in the world. Three load-bearing elements:
- Worldwide scope. The test is not UK-only. A buyer who has previously owned a dwelling in any country (Australia, France, Singapore, anywhere) is not a first-time buyer for SDLT purposes. Cross-border family backgrounds and inherited or gifted overseas property are common disqualifiers. Pre-purchase disclosure of any prior overseas residential ownership is essential.
- Major interest. The disqualifying prior interest must be a major interest, defined under FA 2003 section 117 as freehold or leasehold of more than 21 years. Prior short-term rental tenancies overseas do not engage the test. Long leases (more than 21 years) do. Most overseas residential property ownership patterns are major interests for this purpose.
- Purchaser. The wording is "previously been a purchaser". On a literal reading, inheritance and pure gift do not engage the wording. HMRC's substantive position is that any prior holding of a major interest in a dwelling takes the buyer outside FTB status; the protective reading is to treat prior inheritance or gift of a major interest as disqualifying. Pre-claim advice is sensible where the buyer's history involves any such interest.
The F(No.2)A 2024 section 8 amendment inserted paragraph 6(3) to address a specific bare-trust structuring route. The pre-amendment argument was that where a bare trust held a lease for the benefit of the occupying claimant, the trustee (not the beneficiary) was "the purchaser" for FTB-status purposes, leaving the beneficiary's FTB status intact. The amendment clarifies that the beneficiary's status is what matters: a bare-trust beneficiary holding a major interest is treated as the purchaser. The amendment closed the route without altering the underlying rates or thresholds.
The cash benefit by purchase price
The relief produces materially different SDLT figures across the £0 to £500,000 band. A worked illustration:
- £200,000 purchase: Relief £0 (the full price falls within the £300,000 nil band). Standard residential SDLT £1,500 (£0 on first £125,000; £1,500 on the £75,000 above £125,000 at 2%). Saving £1,500.
- £300,000 purchase: Relief £0 (the full price is within the relief's nil band). Standard residential SDLT £5,000 (£2,500 on the second band plus £2,500 on the £50,000 in the 5% band at 5%). Saving £5,000.
- £400,000 purchase: Relief £5,000 (5% on the £100,000 above £300,000). Standard residential SDLT £10,000 (£2,500 plus £7,500 on £150,000 at 5%). Saving £5,000.
- £425,000 purchase: Relief £6,250 (5% on £125,000). Standard residential SDLT £11,250. Saving £5,000.
- £499,999 purchase: Relief £9,999.95 (5% on £199,999). Standard residential SDLT £14,999.95. Saving £5,000.
- £500,000 purchase: Relief £10,000 (5% on £200,000). Standard residential SDLT £15,000. Saving £5,000.
- £500,001 purchase: No relief. Standard residential SDLT £15,000.05. Saving £0 (cliff edge).
- £600,000 purchase: No relief (£500,000 cap exceeded). Standard residential SDLT £20,000 (£17,500 plus 5% on £100,000 at 5%). Saving £0.
The maximum cash saving plateaus at £5,000 for purchases between £300,000 and £500,000, then drops to £0 once the £500,000 cap is exceeded. The headline £6,250 figure sometimes quoted refers to the SDLT-under-relief on a £425,000 purchase, not the saving relative to the standard rate table. The saving is best understood as the gap between the relief SDLT and the standard SDLT at the same price.
The joint-purchaser rule: every buyer must qualify
Schedule 6ZA paragraph 1(4) requires the purchaser, or if more than one, each of the purchasers, to be a first-time buyer. The rule is transaction-level, not buyer-level: one non-FTB joint purchaser disqualifies the whole transaction. The qualifying buyer cannot claim the relief on their share alone.
The most common failure pattern is a joint purchase by a first-time buyer and a partner (spouse, civil partner, or unmarried partner) who has previously owned residential property. The disqualification is sustained: the first-time buyer also loses FTB status after the joint purchase, because they have now been a purchaser of a major interest. Any subsequent solo purchase is unlikely to re-engage the relief.
Planning options for a first-time buyer with a non-FTB partner who wants to buy a starter home jointly:
- Partner sells first. The non-FTB partner disposes of their existing residential property before the joint purchase. This removes both the FTB-disqualifier and the Schedule 4ZA surcharge. Practical constraints: timing risk on the sale-and-purchase chain; cost of moving twice; CGT considerations on the partner's disposal if not the main residence.
- Sole purchase by the FTB. The first-time buyer purchases alone in their own name with the non-FTB partner providing financial support outside the legal-title arrangement. Practical constraint: mortgage lenders are typically reluctant to lend to a sole borrower on a property to be occupied by a couple; lender requirements often force a joint structure.
- Joint purchase, accept the cost. The couple accepts the SDLT cost of the joint structure and proceeds. The cost is quantified in the next section.
The joint-purchase plus additional dwellings surcharge trap
The joint-purchaser rule operates alongside the additional dwellings surcharge in Schedule 4ZA. Schedule 4ZA paragraph 2 aggregates joint purchasers: the 5% surcharge applies on the whole transaction if any one of the joint purchasers (or any joint purchaser's spouse or civil partner) owns another residential dwelling at the end of the day of the transaction. The double effect on a joint FTB-plus-BTL-partner purchase is severe.
On a £400,000 joint purchase by a qualifying first-time buyer and a partner who owns a buy-to-let property:
- 0% + 5% surcharge on the first £125,000 = 5% × £125,000 = £6,250
- 2% + 5% surcharge on the £125,000 to £250,000 portion = 7% × £125,000 = £8,750
- 5% + 5% surcharge on the £250,000 to £400,000 portion = 10% × £150,000 = £15,000
- Total: £30,000
The same £400,000 property as a sole first-time buyer purchase by the qualifying buyer alone (with the BTL partner outside the transaction) would attract £5,000 of SDLT. The cost of the joint structure is £25,000. The trap recurs at higher prices: a £500,000 joint purchase with the same partner profile attracts £40,000 of SDLT (£6,250 + £8,750 + £25,000) versus £10,000 on the sole-FTB purchase, a £30,000 differential.
The intention-to-occupy and single-dwelling tests
Schedule 6ZA paragraph 1(4) also requires the buyer to intend to occupy the dwelling as the buyer's only or main residence. Investors and second-home buyers cannot claim the relief. The intention is tested at the effective date of the transaction (substantial performance or completion, whichever is earlier). Subsequent changes do not retrospectively withdraw the relief, but the original intention must be genuine.
Schedule 6ZA paragraph 1(2) requires the main subject-matter of the transaction to be a major interest in a single dwelling. Multi-dwelling purchases (two or more dwellings acquired in a single transaction) do not qualify; the relief is starter-home-targeted, not portfolio-targeted. Incidental ancillary interests (a separately-leased garage, a small adjacent parcel of land) do not break the test; a substantive second dwelling does. With Multiple Dwellings Relief abolished from 1 June 2024, the single-dwelling test simply means multi-dwelling transactions are outside Schedule 6ZA entirely.

Shared ownership under paragraphs 6A to 6D
Schedule 6ZA paragraphs 6A to 6D contain the shared-ownership-specific rules. A first-time buyer acquiring a shared-ownership lease (typically from a housing association) has a choice between two SDLT routes.
The market-value election treats the transaction as if the buyer had purchased the full market value of the dwelling at acquisition. SDLT is computed on the full open market value (capped at £500,000 for relief purposes) at the FTB rates. The election is irrevocable for the transaction. No further SDLT arises on subsequent staircasing. The choice locks in the FTB treatment for the full value at acquisition.
The initial-share basis treats SDLT as due only on the share initially acquired plus the net present value of the rental element. SDLT is computed on that smaller chargeable amount. Future SDLT arises if the buyer staircases above 80% ownership (staircasing between 0% and 80% is SDLT-free under the standard shared-ownership rules). The initial-share basis preserves the option of avoiding further SDLT on staircasing below 80% but means the relief is used only on the initial share.
The choice is fact-specific. Market-value election is typically preferred where the buyer intends to staircase to 100% over a short timeframe and the open market value is comfortably under £500,000 (so the relief covers the full chargeable amount in one go). The initial-share basis is typically preferred where the buyer expects to remain at a low share for a long period, or where the open market value exceeds £500,000 so that the market-value election would lose FTB relief entirely while the initial-share basis preserves it on a smaller chargeable amount.
Worked example: shared-ownership lease on a £400,000 open-market-value property, 40% initial share at £160,000, annual rent £6,000 on the unsold 60%. Market-value election: SDLT computed on £400,000 at FTB rates = £5,000; no further SDLT on staircasing. Initial-share basis: SDLT computed on the initial £160,000 (within the £300,000 nil band, so £0) plus net-present-value of the rental on the 60% unsold (computed under FA 2003 Schedule 5; typically minor at sub-£250,000 NPV). Future SDLT arises on staircasing above 80%. The initial-share basis saves £5,000 upfront but defers a potentially-larger SDLT bill into the future; the market-value election locks in the £5,000 cost now and provides certainty.
The corporate, LLP, and trust position
Schedule 6ZA paragraph 1(4) requires the purchaser, or each joint purchaser, to be an individual who is a first-time buyer. Corporate buyers (limited companies, special-purpose vehicles), LLPs holding for company members, and most trust structures fall outside the eligibility wording. The narrow exception is the bare-trust beneficiary route addressed by the F(No.2)A 2024 section 8 amendment.
Substantive trust holdings (interest-in-possession trusts, discretionary trusts, life-interest trusts) do not engage the relief. The corporate-acquisition route is also subject to the FA 2003 Schedule 4A 15% non-natural-person flat rate on dwellings over £500,000, which is materially worse than any residential rate position; buyers contemplating corporate acquisition of a starter home should model both the loss of FTB relief and the Schedule 4A 15% rate before completion.
Practical claim procedure and documentation
The relief is claimed on the SDLT return for the transaction (FA 2003 s.57B(2)). It is not automatic. The return is filed by the buyer's conveyancer at completion and the relief code (currently code 32) is entered on the return form. A return that omits the relief and pays the full standard residential SDLT can be amended within 12 months of the filing date to claim the relief and reclaim the overpayment.
Supporting documentation worth retaining for at least six years after completion:
- The conveyancer's first-time buyer declaration prepared as part of the return-readiness pack.
- Evidence of intention to occupy as main residence (mortgage application stating residential occupation, council tax registration, utilities transfer, electoral roll registration).
- For buyers with cross-border family or asset history, written confirmation of the buyer's prior property history (or absence of any prior holding) from any relevant overseas family members or advisers.
- For shared-ownership purchases, copies of the election made on the SDLT return (initial-share basis or market-value election) and the consideration breakdown.
- For any prior trust interests, copies of the trust deed and any termination documentation.
HMRC's enquiry window for SDLT is generally four years from the return filing date, extended to six years for careless inaccuracies and twenty years for deliberate inaccuracies. Retention for the long end of those windows is the cautious posture for buyers with any prior-ownership ambiguity.
