Non-Resident UK Tax Estimator

What does the non-resident UK tax estimator do?

Direct answer: It estimates your UK Income Tax as a non-resident and compares the two bases HMRC tests for you: Method 1 treats your UK dividends and savings as disregarded income — capping the tax on them but costing you the £12,570 personal allowance — and Method 2 taxes everything normally, with the allowance. It shows both, names the lower, and explains why (HMRC HS300, 2026; gov.uk Income Tax rates; 2026/27).

Becoming non-resident does not switch off UK tax on UK-source income. Rent from a UK property, dividends from a UK company, interest from a UK bank, a UK pension and pay for UK workdays all stay within UK Income Tax after you leave. What changes is how the bill is worked out — and that's where the disregarded-income rule, the lever this tool is built around, comes in. HMRC wrote the rules; we translated them, dated them, sourced them, and built the comparison.

How does the estimator work?

Direct answer: It computes your UK tax both ways — disregarding UK dividends and savings (capping that tax but losing the personal allowance) and on the normal basis (taxing everything but keeping the allowance) — and shows the lower, which is what HMRC charges. The bigger your dividends and interest, the more disregarding wins. See UK dividends and savings when non-resident (HMRC HS300, 2026).

The point of the disregarded-income rule is a cap on a non-resident's UK liability. HMRC limits your tax to the lower of two figures: the tax on your non-disregarded income, worked out with no personal allowance, plus any tax deducted at source on the disregarded income; or the normal calculation, with personal allowances. Because UK dividends carry no tax deducted at source, and UK interest has been paid gross since April 2016, the "tax deducted at source" part is usually nil — so Method 1 effectively shelters your UK dividends and interest, but only at the price of your personal allowance against everything else.

Why does HMRC work it out two ways — and which one applies to me?

Direct answer: Because the disregarded-income cap is a relief, not a trap: HMRC computes your bill both ways and charges the lower, so you never lose out by it. You don't choose — but the winner tells you what's driving your bill. Method 1 wins when your UK dividends and savings are large; Method 2 wins when they're modest and the £12,570 allowance is worth more than the shelter (HMRC HS300, 2026; 2026/27).

The trade-off in one line: shelter your dividends and interest, but lose your allowance (Method 1) — or keep your allowance and tax everything (Method 2)? A UK company director drawing large dividends is the classic Method 1 case; a retiree on a modest UK pension with a little interest is the classic Method 2 case. The tool runs both for your exact figures so you can see the gap.

What 2026/27 rates does the estimator use?

Direct answer: It uses the 2026/27 UK rates for England, Northern Ireland and Wales — the personal allowance, the income-tax bands, and the new dividend rates that took effect on 6 April 2026 (gov.uk Income Tax rates; Tax on dividends; 2026/27).

• Personal allowance £12,570 — frozen to 5 April 2028.
• Basic rate 20% on the first £37,700 of taxable income (higher-rate threshold £50,270).
• Higher rate 40% on income over £50,270 up to £125,140; additional rate 45% above £125,140.
• Dividend allowance £500; dividend rates 10.75% / 35.75% / 39.35% (ordinary / upper / additional — up from 8.75% / 33.75% / 39.35% on 6 April 2026).
• Personal Savings Allowance £1,000 / £500 / £0 (basic / higher / additional rate); starting rate for savings a £5,000 band at 0%, reduced by non-savings income above the allowance.

Dividends are taxed as the top slice of income, savings interest after non-savings income, and non-savings income (rental, pension, UK-workday pay) at the bottom — the tool applies that order to both methods so the comparison is fair.

What UK income stays taxable after I leave — and what doesn't?

Direct answer: UK-source income stays UK-taxable: UK rent (always — it's not disregarded), pay for UK workdays, a UK private pension (unless a treaty exempts it), and — within the disregarded-income cap — UK dividends and interest. What falls out of UK Income Tax is your foreign income after you've broken residence. Capital gains on UK property are a separate charge, not covered here (gov.uk "Tax on your UK income if you live abroad"; HMRC HS300, 2026; 2026/27).

Two things this estimator deliberately leaves to other tools and guides: UK rental income and the Non-Resident Landlord Scheme — your letting agent or tenant may withhold 20% basic-rate tax unless HMRC approves you to receive it gross on form NRL1, but that's collection, not an extra tax (the rental-only picture lives in the Non-Resident Landlord tax calculator and the UK rental income guide); and the temporary non-residence clawback — if you come home within five full tax years, close-company dividends and certain other income banked while away are taxed in your year of return (see managing money after leaving the UK).

Do I keep the personal allowance?

Direct answer: Only if entitled — as a British citizen, EEA national, Crown employee, or where a treaty grants it. Most UK leavers keep it via citizenship. UK rental income is always taxable and never disregarded.

Is this calculator — and treating my dividends as disregarded — legal?

Direct answer: Yes. The disregarded-income cap is a relief written into UK tax law; HMRC applies it for you and charges the lower of the two bases. You report your UK income openly on a Self Assessment return (with the SA109 residence pages) — it's the opposite of hiding anything. This tool estimates the position; it doesn't file anything, store your figures, or replace the official route or a qualified adviser (HMRC HS300, 2026; gov.uk; 2026/27).
