Frequently Asked Questions
Is this website financial or tax advice?
No. This calculator is an educational tool. It uses averages and published figures to illustrate how taxes can add up — it does not tell you what you personally owe or what you should do. For your real tax position, use HMRC (including their calculators and guidance) or speak to a qualified accountant or tax adviser.
How much income tax do I pay in the UK?
Income tax is charged at 0% on your personal allowance, then in increasing bands — 20% basic rate, 40% higher rate, and 45% additional rate. The thresholds change each year; use the tax year selector above to see the exact figures for your year. If you earn over £100,000, your personal allowance gradually reduces and disappears entirely once your income is high enough.
How much National Insurance do I pay?
Employees pay National Insurance on earnings above the primary threshold, and a reduced rate above the upper earnings limit. The exact rates and thresholds have changed several times — notably they were higher before cuts in 2024. Use the tax year selector to see the precise figures for your year. NI is calculated on gross salary — pension salary sacrifice reduces both income tax and NI.
How much money does the UK government take from me in total?
Most people focus on income tax and NI, but the government also collects VAT (20% on most goods), fuel duty (around 53p per litre), alcohol duty, council tax, and more. For a typical £35,000 salary, total tax across all categories is typically £10,000–£13,000 per year — an effective rate of 30–37%. Our calculator shows the full picture.
What is my effective tax rate?
Your effective (or average) tax rate is total tax paid divided by gross salary. It is always lower than your marginal rate. At £35,000 the PAYE effective rate is around 18%; when you add spending taxes it rises to 30–35%. At £50,000 the PAYE rate is around 21% and the total effective rate is around 35%.
What is take-home pay? How is it calculated?
Take-home pay (or net pay) is your gross salary minus income tax and National Insurance. For example, on a £35,000 salary the take-home is typically around £27,500–£28,000 depending on the tax year. Pension salary sacrifice reduces your taxable income first, so it saves you both income tax and NI. Enter your salary in the calculator above for an exact figure. See our take-home pay guide.
Does the calculator cover Scotland?
Yes — use the Tax Region toggle above the form to switch between England / Wales / N.I. and Scotland. Scotland has its own income tax rates and bands set by the Scottish Parliament (including Starter, Intermediate, Advanced and Top Rate bands), and the calculator uses the correct rates for whichever year you have selected. Your choice is remembered for future visits. More detail: Scottish income tax.
How is VAT calculated in this tool?
We estimate your VAT by assuming you spend 90% of your take-home pay and that approximately 45% of that spending is on VATable goods and services (based on ONS household expenditure data). VAT of 20% is then applied to that proportion. This gives a reasonable average — your actual VAT bill will vary based on your specific spending habits.
How is council tax calculated?
Council tax is set by your local authority based on your property's valuation band (A–H in England, A–I in Wales). The national average is around £2,000–£2,200 per year for a Band D property, but it varies significantly by area. Single occupants get a 25% discount. Our calculator includes council tax in your total tax burden — you can opt out if you're exempt.
Can I reduce my tax bill with pension contributions?
Yes — pension contributions via salary sacrifice reduce both your income tax and National Insurance, because they lower your taxable pay before either is calculated. For a basic-rate taxpayer contributing 5% of a £35,000 salary, this saves around £350 in income tax and £140 in NI per year. Enter your pension percentage in the calculator above to see your exact saving.
What are the Scottish income tax rates?
Scotland has its own income tax rates set by the Scottish Parliament. There are six bands: Starter (19%), Basic (20%), Intermediate (21%), Higher (42%), Advanced (45%) and Top (48%). The higher and top rates are notably higher than the rest of the UK. Use the Scotland toggle in the calculator to see how this affects your take-home pay.
How do I use this calculator?
Enter your gross pay before tax and choose how often you are paid: per year, per month, per week, per working day (×260), or per calendar day (×365). We convert that to an annual amount for tax. Then select a tax year (default is the current year), your region (England/Wales/N.I. or Scotland), and optionally driving, alcohol, pension and salary sacrifice.
