When is stamp duty paid on a £1,000,000 purchase?

Standard home mover	£43,750	4.38%
Additional property (2nd home / BTL)	£93,750	9.38%

First-time buyer at £1,000,000

First-time buyer relief does not apply above £500,000. At £1,000,000 the FTB pays the standard £43,750.

Band-by-band: 0% on the first £125,000 (band £0–£125,000) = £0 · 2% on the next £125,000 (band £125,000–£250,000) = £2,500 · 5% on the next £675,000 (band £250,000–£925,000) = £33,750 · 10% on the next £75,000 (band £925,000–£1,000,000) = £7,500. Total: £43,750.

Standard home mover at £1,000,000

For a home mover replacing their only or main residence:

Additional property at £1,000,000

For a buy-to-let, second home, or any purchase where the buyer will own another residential property at the end of the day of completion:

Band-by-band: 5% on the first £125,000 (band £0–£125,000) = £6,250 · 7% on the next £125,000 (band £125,000–£250,000) = £8,750 · 10% on the next £675,000 (band £250,000–£925,000) = £67,500 · 15% on the next £75,000 (band £925,000–£1,000,000) = £11,250. Total: £93,750.

That's £50,000 more than the standard rate. The 5% additional-property surcharge stacks on every band above the £40,000 entry threshold.

Deposit, mortgage and cash needed at £1,000,000

Stamp duty is paid on top of your deposit, so the cash you need on completion day is the deposit plus SDLT (plus the fees listed further down). The table shows three common deposit levels at £1,000,000, with the repayment on the rest of the price. First-time buyer relief does not apply at this price, so first-time buyers pay the home-mover figure.

Deposit %	Deposit amount	Mortgage	Monthly repayment*	Deposit + SDLT (home mover)
10%	£100,000	£900,000	£5,002	£143,750
25%	£250,000	£750,000	£4,169	£293,750
40%	£400,000	£600,000	£3,335	£443,750

*Capital-and-interest repayment over 25 years at an illustrative 4.5% interest rate. This is an assumption to show scale, not a quote or a forecast. At 5.0% the 25%-deposit repayment rises by about £216 a month. Model your own rate and term with the mortgage repayment calculator, and check what you can borrow with the affordability calculator.

£1,000,000 in other situations

The headline table covers UK-resident buyers in England and Northern Ireland. These are the figures at exactly £1,000,000 for non-UK residents and for the same price in Scotland and Wales, which have their own taxes.

Situation at £1,000,000	Tax
Non-UK resident home mover (England/NI, +2%)	£63,750
Non-UK resident, additional property (England/NI, +5% and +2%)	£113,750
Scotland, main home (LBTT)	£78,350
Scotland, first-time buyer (LBTT relief)	£77,750

Wales, additional property (LTT higher rates)	£111,200

Worked example: the 10% band above £925,000

£925,000 is where a home mover's marginal rate doubles from 5% to 10%. At £1,000,000 the bill is £36,250 on the first £925,000 plus £7,500 on the last £75,000, giving £43,750. Agreeing £950,000 instead would cost £38,750 (£5,000 less), and £925,000 would cost £36,250.

For an additional property the marginal rate in this band is 15% (17% for a non-UK resident), so the same £75,000 above £925,000 costs £11,250.
