— Understanding the result
This UK income tax calculator applies the personal allowance, savings nil-rate bands, dividend allowance and statutory tax bands in the correct order. It shows income tax before National Insurance, student loans and HICBC, then reconciles the band tax and any Gift Aid donor tax-cover charge to visible rows.
— How it's calculated
How taxable income is stacked
Non-savings income is considered before savings income, with dividends above both. The engine then allocates the personal allowance in the way permitted by ITA 2007 s.25(2) and applies the savings and dividend nil-rate bands. See HMRC’s published Income Tax rates and allowances.

Gift Aid and relief-at-source pension inputs
Gift Aid and relief-at-source pension contributions are entered separately. The pension amount affects adjusted net income and the rate limits only within the shared member-contribution cap: the greater of relevant UK earnings and £3,600, less other relievable member contributions already using that cap. Employer contributions do not use it. Pensions, property, savings and dividends are not relevant UK earnings. Enter employment income as taxable pay after any net-pay pension deduction (normally the P60 figure), but enter relevant UK earnings before that deduction. The other member-contributions amount consumes the cap and is not deducted twice. A pension contribution paid gross and relieved by claim, for example to a retirement annuity contract, has its own field: it is deducted once, from non-savings income unless setting part against savings or dividend income gives less tax (tax years to 2026-27). It counts against the same cap, but only up to relevant UK earnings (the £3,600 floor applies to relief at source alone). See HMRC’s pension tax-relief conditions and adjusted net income guidance and net-pay worked example.

Gift Aid tax-cover check
A donor must be charged enough UK Income Tax or Capital Gains Tax to cover the tax reclaimed on all Gift Aid donations. Enter only cover outside this calculator; the ordinary income tax shown here is counted automatically, but HICBC cannot count as Gift Aid cover. Any remaining shortfall is shown as the separate donor charge required by ITA 2007 s.424. HMRC’s Gift Aid guidance explains the tax-cover requirement.

What the income-tax total includes
The headline is income tax only. National Insurance, student-loan deductions and the High Income Child Benefit Charge are separate liabilities. The HICBC overlay in the marginal map is illustrative; use the dedicated calculator with the actual Child Benefit award for the statutory charge.
Scottish taxpayer calculations
Scottish rates apply to non-savings income only. Savings and dividend rates remain UK-wide. The tool offers Scotland only for tax years with a verified Scottish config, so it never silently substitutes rest-of-UK bands.

— How to calculate UK income tax by income type
Step 1
Choose the tax year and regime
Select the UK tax year. For the rest of the UK nothing more is needed; for a Scottish taxpayer, open Add other income or details and choose Scottish taxpayer under Income tax regime.
Step 2
Enter each income stream
Enter non-savings income (gross, after net-pay relief), gross savings income and dividend income before allowances.
Step 3
Enter relief and tax-cover facts
Under Add other income or details, enter grossed-up Gift Aid and total gross pension contributions paid net of tax (relief at source). If you pay relief-at-source contributions, also enter relevant UK earnings and other member contributions already reflected in taxable pay that use the shared earnings cap. Enter a pension contribution paid gross and relieved by claim, for example to a retirement annuity contract, under Pension contributions relieved by claim, with relevant UK earnings: it is deducted once, from non-savings income unless setting part against savings or dividend income gives less tax (tax years to 2026-27). If you enter Gift Aid, add any qualifying UK Income Tax or CGT cover outside this calculator.
Step 4
Review the reconciled tax bands
Check each allowance and rate-band row, the relief-eligibility check and any separate Gift Aid tax-cover charge.
Step 5
Check separate liabilities
Review HICBC, National Insurance and other deductions separately because they are not included in the income-tax total.

— Frequently asked questions
Does this income tax calculator include National Insurance?
No. The headline and band table calculate income tax only. Employee or self-employed National Insurance, student-loan deductions and other payroll deductions are separate.
Does the total include the High Income Child Benefit Charge?
No. HICBC is a separate statutory charge based on adjusted net income and actual Child Benefit entitlement. The marginal map can illustrate its average effect, while the dedicated HICBC calculator calculates the charge.
Does the calculator support Scottish income tax?
Yes, for tax years with verified Scottish bands. Scottish rates apply to non-savings income; savings and dividend rates remain UK-wide.
Why are Gift Aid and pension contributions separate?
Both can extend tax bands and reduce adjusted net income, but pension relief is subject to a shared cap across member contributions: relevant UK earnings, with the £3,600 basic-amount rule for relief at source. Gift Aid has a separate donor tax-cover requirement. Combining them can overstate relief or omit an ITA 2007 s.424 charge.
Why can the marginal rate be 60% above £100,000?
Between £100,000 and £125,140, £1 of personal allowance is withdrawn for every £2 of adjusted net income. Under rUK higher-rate tax, that allowance withdrawal adds 20 percentage points to the 40% rate, producing a 60% income-tax marginal rate.
