Stamp Duty for First-Time Buyers: What You Pay and the £500k Cliff (UK, 2026)

By Published 7 min read

If you are buying your first home in England or Northern Ireland, first-time buyer relief means no Stamp Duty on the first £300,000 and 5% only on the portion between £300,001 and £500,000. Buy at £295,000 and you pay £0; at £400,000 you pay £5,000 instead of the standard £10,000. But the relief has a hard edge: one pound over £500,000 and you lose all of it. This guide works the examples and the traps — check your own price in the stamp duty calculator.

How first-time buyer relief works

Stamp Duty Land Tax (SDLT) is charged in slices, like income tax. For first-time buyers on homes up to £500,000, the bands are:

Slice of priceFirst-time buyer rateStandard rate
Up to £125,0000%0%
£125,001 – £250,0000%2%
£250,001 – £300,0000%5%
£300,001 – £500,0005%5%
Over £500,000Relief lost — standard rates on everything5%+ (10% above £925k)

The relief is worth up to £6,250 versus a standard buyer (the 0% treatment of the £125k–£300k slices). Rates and thresholds do change at Budgets — the calculator stays on current bands, so use it for the live figure.

Worked examples: £250k, £400k, £501k

  • £250,000: entirely inside the 0% first-time band → £0 (a standard buyer pays £2,500).
  • £400,000: £0 on the first £300k, 5% on the next £100k → £5,000 (standard buyer: £10,000).
  • £501,000: relief gone. Standard bands apply to the whole price → £15,050. That extra £1,000 of house price cost £5,000+ in tax.

The £500,000 cliff edge

Unlike the sliced bands, the relief threshold is all-or-nothing: at £500,000 you pay £10,000; at £500,001 you pay £15,050. If you are negotiating near the cliff, this is real money — a £505,000 asking price is genuinely worth negotiating to £500,000, because the seller's £5,000 concession saves you over £10,000 all-in. Fixtures and fittings paid for separately (at fair value) can also legitimately keep the property price at or under the line; your conveyancer will keep that honest.

Who counts as a first-time buyer

  • You must never have owned a residential property — anywhere in the world, including inherited property and shares of property.
  • Every joint buyer must qualify. Buying with a partner who owned a flat years ago removes the relief entirely.
  • The home must be your main residence — the relief never applies to buy-to-let.
  • Owning commercial property (with no dwelling) does not disqualify you.

Budgeting it into your purchase

Stamp duty is due within 14 days of completion and — unlike the deposit — cannot be borrowed as part of a normal mortgage, so it comes from cash on top of your deposit, legal fees and survey. On a £400,000 first home, budget roughly: £5,000 SDLT + £1,500–£2,500 conveyancing + £500–£1,000 survey. Run the exact duty for your price — and compare the first-time and standard figures — in the stamp duty calculator, and sense-check the monthly affordability with the salary breakdown calculator. (Scotland and Wales tax property differently — LBTT and LTT — so use jurisdiction-specific rates there.)
