Non-Resident Stamp Duty Calculator 2026

Market snapshot: the non-resident surcharge is currently 2% of the purchase price — treat that figure as a snapshot, since it is a live political target. Labour's 2024 manifesto commits to raising it to 3%, but that change has survived two fiscal events unimplemented. The next fiscal event is the Autumn Budget, 28 October 2026 — a rate change there would affect any purchase completing afterwards.

Rate current as at August 2026. Check gov.uk before completing if your purchase date is close to a fiscal event.

Individual buyers only — purchases through a company, trust or partnership follow different rules.

Purchase price

Completion date

A date in the past is fine — if you've already completed, this checks where you stand.

Is this an additional property?

First-time buyer?

Are you buying jointly with a UK-resident spouse or civil partner you live with?

“Living together” has a statutory meaning: you are treated as living together unless you are separated by court order, separated by deed, or separated in circumstances likely to be permanent. Both of you must be purchasers, jointly entitled to the property.

When will you be living in the UK from?

The tool assumes you are continuously present in the UK from this date onward — see the note next to your result.

How this calculator works

The 2% surcharge is the easy part. The dates that decide whether you can reclaim it are where this calculator earns its place.

The dates, not just the tax

Every competitor stops at the 2% surcharge. This tool works out when you become eligible to reclaim it, and the last day you can make that claim.

The residence test

You need 183 days of UK presence within any continuous 365-day period, and that period must sit inside a window running from 364 days before completion to 365 days after it.

The refund is never automatic

If you qualify, the surcharge is reclaimed by amending your SDLT return, not paid back automatically. A conveyancer or tax adviser can do this for you.

The two-year deadline

The claim must be made within two years of completion. Miss it and the refund is lost, even if you met the residence test.

Frequently asked questions

What does this calculator work out?

It works out three things: the 2% surcharge you will pay at completion, the date you become eligible to claim it back, and the last day you can make that claim. The dates are the part most buyers get wrong, so they are shown first.

Where do the dates come from?

From the statutory residence test for the surcharge. You need 183 days of presence in the UK within any continuous 365-day period, and that period has to sit inside a window running from 364 days before completion to 365 days after it. The calculator works out when your 183rd day lands inside that window.

Why does it assume I move to the UK once and stay?

Because modelling scattered trips properly would need a day-by-day calendar of every visit, and no one will fill that in. Assuming a single move-in date is the cautious direction: if you have already spent time in the UK on separate trips, you may qualify earlier than the calculator shows, and your real deadline to arrive may be later.

Can I use this if I have already completed?

Yes. Enter your actual completion date, even if it has passed. The calculator will tell you whether you already meet the residence test, whether you still can, and whether your two-year claim deadline has run out.

Why does it sometimes say I should not pay the surcharge at all?

Three situations produce that answer: you were already UK resident for this test on the day you completed, you are buying jointly with a UK-resident spouse or civil partner you live with, or the purchase price is under £40,000, below which the surcharge does not apply.

Does this calculator make the claim for me?

No. Refunds are never automatic and never paid without a claim. You get one back by amending your stamp duty return, which your conveyancer or a tax adviser can do for you. This tool tells you the dates and the amount; it does not produce any document.

Ready to check your dates?

Work out your dates before you complete, not after — the last-viable move-in date and the claim deadline are both fixed the moment your completion date is set.

Sources & Methodology

Surcharge and total SDLT figures use the same shared engine as the Stamp Duty Calculator. The qualification date, claim deadline and last-viable-arrival date come from a closed-form model derived from the residence-test statute, independently re-derived twice and checked against a brute-force day-by-day simulation across 46,400 date pairs with zero mismatches.
