Stamp duty is usually the biggest single cost of a buy to let purchase after the deposit, because an additional residential property pays a 5% surcharge on top of every standard band. Here are the current numbers for England, worked through at real prices, all checked against GOV.UK this week.
The current rates on a buy to let
Standard residential bands: nothing to £125,000, then 2% to £250,000, 5% to £925,000, 10% to £1.5 million and 12% above. A buy to let, or any additional residential property over £40,000, adds 5% on top of each band, which works out as an extra 5% of the whole price.
Two worked examples
A £250,000 buy to let: the standard bands produce £2,500, and the surcharge adds 5% of £250,000, another £12,500. Total £15,000. A £300,000 buy to let: standard bands £5,000, surcharge £15,000, total £20,000. Notice the pattern: on typical purchase prices, the surcharge is most of the bill.
Buy to let adds a 5% surcharge on top of every standard stamp duty band
A £250,000 buy to let in England costs £15,000 in stamp duty at current rates
The surcharge applies to any additional residential property costing over £40,000
Sell your old main home within 36 months and the surcharge on your replacement can be refunded
Moving property into a company triggers stamp duty too, price it before restructuring
When does the surcharge apply?
Whenever you complete on a residential property over £40,000 and end up owning more than one, anywhere in the world, unless the new one replaces your main residence. Married couples and civil partners count as one unit, so a property in your spouse’s name still counts against you. Companies pay the surcharge on residential purchases as standard.
Can you avoid stamp duty on a buy to let?
Mostly, no, and I would rather say so plainly than let you find out from a scheme promoter. The genuine edges: a purchase replacing your main residence is not an additional property; sell your previous main home within 36 months and you can reclaim a surcharge you paid; and genuinely mixed-use or six-plus-dwelling purchases fall under non-residential rates. Anything cleverer than that belongs in front of a tax adviser before you rely on it, and most of it does not survive contact with one.
Stamp duty when moving property into a company
Transferring a property you already own into your limited company is a purchase in the company’s eyes, at market value, with the surcharge. It is one of the main costs that decides whether incorporation is worth it, covered properly in my guide to transferring property into a limited company.
First time buyer buying a buy to let?
An odd corner worth knowing: if a buy to let is the only property you will own, there is no surcharge, because it is not additional. But first time buyer relief does not apply either, since you will not live there, so you pay standard rates. And spending first time buyer status on a rental has knock-on costs when you later buy your own home.

Run your own numbers
My stamp duty calculator handles the standard and additional-property sums for any price. For the full picture of what a purchase costs beyond the tax, my guide to buy to let deposits covers the rest of the cash you need on the day.
One practical note on timing
Stamp duty is due within 14 days of completion, and your solicitor files and pays it from funds you provide at completion. It cannot be added to the mortgage, so it sits alongside the deposit in your cash planning, not inside the loan.
Price the whole purchase before you offer
Tell me the price and how you plan to own it, and I will give you the full cash requirement: deposit, stamp duty, fees, the lot. Book a call, phone 01425 203055, or WhatsApp 07731 675537. Scotland and Wales run their own systems with different rates, so cross-border purchases need their own sums.
