SDLT uses a progressive slab system — each band applies only to the slice of the purchase price that falls within it, not the full amount. On a £625,000 standard residential purchase, the total SDLT is £21,250. Only the portion of the price within each band is taxed at that band’s rate — which is why the effective rate (3.40%) is always lower than the top marginal rate applied to the final slice.
The three buyer-type scenarios at £625,000
The same £625,000 property attracts different SDLT depending on your circumstances. A standard residential buyer pays £21,250. A first-time buyer pays £21,250 — because FTB relief provides a nil rate threshold of £425,000 and a 5% rate on the portion above that. A buy-to-let or additional property purchase costs £52,500, due to the 5% surcharge applied across every band from the first pound (in force from 31 October 2024).
When SDLT is due and who pays it
The SDLT return must be filed and the £21,250 paid within 14 days of completion. Your solicitor or licensed conveyancer handles this as part of the conveyancing process — you do not file directly with HMRC. The cost is factored into their completion statement alongside the Land Registry registration fee and their own charges. SDLT cannot be paid in instalments; it must be settled in full at completion.
Effective rate vs marginal rate
The effective rate on this £625,000 purchase is 3.40% — this is the total SDLT (£21,250) divided by the purchase price. The effective rate is always lower than the top marginal band rate because only the portion of the price in each band is taxed at that rate. This is why SDLT does not create a cliff-edge in the same way as a flat-rate stamp duty system would.
Frequently asked questions
How much stamp duty do I pay on a £625,000 property?
Stamp duty (SDLT) on a £625,000 property in England is £21,250, an effective rate of 3.40%. This is calculated using the standard residential bands: 0% on the first £125,000, 2% on £125,001–£250,000, 5% on £250,001–£925,000, 10% on £925,001–£1.5m, and 12% above £1.5m.
What is the effective stamp duty rate on £625,000?
The effective SDLT rate on a £625,000 purchase is 3.40%. This is the total tax (£21,250) divided by the property price. The effective rate is always lower than the top marginal rate because SDLT uses a progressive slab system — each band only applies to the portion of the price within that band.
When do I have to pay stamp duty on a £625,000 property?
You must file your SDLT return and pay the £21,250 stamp duty within 14 days of completion. Your solicitor or conveyancer normally handles this on your behalf. Late filing incurs automatic penalties: £100 if up to 3 months late, rising to £200 after 3 months, plus interest on the outstanding tax.
Can I avoid stamp duty on a £625,000 property?
The only ways to legally reduce stamp duty on a £625,000 property are: (1) if you are a first-time buyer (nil rate up to £425,000), (2) if the property is below £125,000 (nil rate band), or (3) if you transfer the property between spouses/civil partners (exempt). Stamp duty cannot be avoided by structuring the purchase differently — HMRC's anti-avoidance rules are strict.
Can stamp duty on £625,000 be added to my mortgage?
You cannot directly add stamp duty to your mortgage. However, some lenders allow you to borrow more than the property value to cover SDLT and other costs — effectively bundling the £21,250 into your loan. This increases your LTV ratio and may affect the mortgage rate available to you. Most buyers pay stamp duty from their savings at completion.
How much stamp duty would I pay in Scotland or Wales on £625,000?
Scotland and Wales have their own property transaction taxes. In Scotland, LBTT (Land and Buildings Transaction Tax) uses different bands starting at £145,000. In Wales, LTT (Land Transaction Tax) has a nil rate band up to £225,000. Use the calculator above to compare rates across all three jurisdictions.
What are all the upfront costs when buying a £625,000 property?
Stamp duty is £21,250. Other typical upfront costs include: solicitor/conveyancing fees £1,500–£3,000; homebuyer survey £400–£1,000 (or £800–£1,500 for a full structural survey); mortgage arrangement fee £0–£2,000 (often added to the loan); lender valuation fee £150–£400 (sometimes waived); mortgage broker fee £0–£500; and Land Registry registration fee £540. Budget for £3,000–£8,000 in transaction costs on top of your deposit and SDLT.
Can I pay stamp duty in instalments on a £625,000 property?
No — SDLT must be paid in full within 14 days of completion. There is no instalment arrangement available with HMRC. However, some mortgage lenders allow you to borrow a slightly larger sum to cover SDLT and other transaction costs, effectively spreading it over the life of the mortgage. This increases your loan-to-value ratio and may affect the mortgage rate available to you. Most buyers pay SDLT from savings at completion.
We are buying the £625,000 property jointly — do we both pay stamp duty?
Stamp duty is charged on the transaction, not per buyer. The £21,250 SDLT applies to the purchase as a whole, regardless of whether you are buying alone or jointly. However, the buyer type matters: if both buyers are first-time buyers, FTB relief applies. If either buyer previously owned a property, standard rates apply. If either buyer already owns another property and is not replacing their main home, the 5% buy-to-let/additional dwelling surcharge applies to the whole purchase.
