How much tax will I pay on £150,000 in the UK for 2025/26?
+
On £150,000 you lose your entire personal allowance (it tapers away above £125,140), giving about £53,700 of income tax plus roughly £5,000 of employee National Insurance — a combined effective rate near 39% and take-home of about £91,300. Use the calculator above for your exact figure.
What is the UK personal allowance for 2025/26?
+
The tax-free personal allowance is £12,570 for 2025/26. It reduces by £1 for every £2 you earn above £100,000, so it is fully withdrawn once your income reaches £125,140. This creates an effective 60% marginal rate between £100,000 and £125,140.
What are the UK income tax bands for 2025/26?
+
For England, Wales and Northern Ireland: 0% up to £12,570 (personal allowance), 20% basic rate to £50,270, 40% higher rate to £125,140, and 45% additional rate above £125,140. Scotland sets its own bands and rates.
How is employee National Insurance calculated in 2025/26?
+
Employees pay Class 1 National Insurance at 8% on earnings between £12,570 and £50,270, and 2% on earnings above £50,270. This calculator includes employee NI in your take-home figure.
Why is the marginal rate 60% between £100,000 and £125,140?
+
Because for every £2 earned in this band you also lose £1 of personal allowance, that lost allowance is taxed at 40%. Combined with the 40% on the income itself, the effective marginal rate reaches 60% — 62% once National Insurance is added.
Do US citizens living in the UK still pay US tax on this income?
+
Yes. US citizens and Green Card holders file a US return on worldwide income regardless of residence. UK income tax paid is generally credited against US tax via the Foreign Tax Credit (Form 1116) or excluded under the FEIE, but a US filing obligation remains every year.
Does this calculator include Scottish income tax rates?
+
No. This tool uses the England, Wales and Northern Ireland bands. Scotland has additional bands (starter, basic, intermediate, higher, advanced and top rates), so Scottish taxpayers should treat the result as indicative only.
Is my UK pension contribution tax-free?
+
Personal and workplace pension contributions generally receive UK income-tax relief and can also restore some personal allowance by reducing 'adjusted net income'. This calculator shows gross salary; contributions would reduce the taxable figure. US citizens should confirm the US treatment of UK pension contributions separately.
What is 'adjusted net income' and why does it matter?
+
Adjusted net income is your total taxable income less certain reliefs such as gift-aid and pension contributions. It determines your personal allowance taper (above £100,000) and High Income Child Benefit Charge, so managing it is a key UK planning lever for higher earners.
How much is take-home pay on a £250,000 UK salary?
+
On £250,000 you pay income tax across all bands (with no personal allowance) plus National Insurance, leaving roughly £140,000–£145,000 take-home. Enter your figure above for a precise result, and model the US position if you are a US person.
Does the calculator include dividends or capital gains?
+
No — it covers employment/self-employment income taxed at income-tax rates. UK dividends and capital gains have their own rates and allowances, and for US persons they interact with US tax differently, which is where cross-border planning matters.
When are UK income tax and payments on account due?
+
Self Assessment online returns and any balancing tax are due by 31 January after the 5 April tax year end, with payments on account due 31 January and 31 July. Employees taxed under PAYE have tax collected at source.
How can high earners legally reduce UK income tax?
+
Common levers include pension contributions, gift-aid donations, EIS/VCT investments, salary-sacrifice arrangements and timing of income — several of which also restore the personal allowance. For US citizens each must be checked against US tax to avoid creating a US liability.
Does this tool account for the High Income Child Benefit Charge?
+
No. If you or your partner has adjusted net income above the threshold, a portion of Child Benefit is clawed back through Self Assessment. This calculator focuses on income tax and National Insurance only.
Is this calculator suitable for cross-border US-UK taxpayers?
+
It gives an accurate UK-side estimate, which is the essential starting point for cross-border planning. The UK tax it shows typically becomes your US Foreign Tax Credit — but the interaction (PFICs, pensions, timing) needs a specialist. Book a consultation for a full dual-country picture.
