Tax on Multiple Income Sources: 2026/27 UK Guide

Updated for 2026/27. UK Income Tax is calculated across your total income, even when different sources use PAYE, Self Assessment or separate allowances. Build one complete picture of employment, self-employment, rent, pensions, savings, dividends, foreign income and gains before deciding what tax is due.

List every income source

• Employment salary, bonuses and benefits
• Self-employed and partnership profit
• Property rental income
• State, workplace and private pensions
• Bank and building-society interest
• Dividends and investment distributions
• Foreign income
• Trust and estate income
• Miscellaneous, platform and cryptoasset income

Capital disposals are reported separately but can affect adjusted net income, payments and filing requirements.

How income is stacked

For most UK calculations, non-savings income is taxed first, savings income next and dividends last. Personal Allowance is allocated under statutory rules to minimise liability. Savings and dividends have separate 0% allowances but still occupy tax bands.

Scottish rates apply to relevant non-savings, non-dividend income of Scottish taxpayers, while UK-wide savings and dividend rates continue to apply.

Personal Allowance

The standard allowance is £12,570 for 2026/27 and applies once across total income. It is reduced by £1 for every £2 of adjusted net income above £100,000 and is normally lost at £125,140. Do not give each job or business its own allowance.

PAYE and Self Assessment

PAYE deductions from salary and pensions are credits against the final annual liability. Self Assessment adds other income, recalculates the whole position and deducts tax already paid. A correct employment code does not settle rental, business, foreign or capital-gains liabilities automatically.

Self-employment and employment

Self-employed profit sits on top of other taxable income and can enter higher-rate bands. Class 1 National Insurance applies to employment; Class 4 can apply to self-employed profit. Annual maximum rules may affect combined contributions.

Savings interest

The Personal Savings Allowance is up to £1,000 for a basic-rate taxpayer, £500 for a higher-rate taxpayer and nil for an additional-rate taxpayer. Other income can change your taxpayer status and reduce the allowance. Low earners may also qualify for the £5,000 starting rate for savings.

Dividends

Dividends are taxed after non-savings and savings income. The dividend allowance is a 0% band, not an exclusion from total income. Company owners should include dividends alongside salary, benefits and other sources.

Property income

Individual landlords report taxable rental profit after allowable costs and relevant finance-cost restrictions. The £1,000 property allowance may be available, but cannot always be combined with actual expenses or connected-party income. Joint owners report their beneficial shares under the relevant rules.

Foreign income

UK residents may need to report foreign salary, rent, pensions, interest and dividends, converting amounts to sterling. Foreign tax credit relief can reduce double taxation. From April 2025, qualifying new residents may claim the four-year foreign income and gains regime, subject to conditions.

High Income Child Benefit Charge

The charge can apply where adjusted net income exceeds the current threshold and you or a partner receives Child Benefit. The 2026/27 test uses individual adjusted net income, not combined household income. Pension and Gift Aid adjustments can affect it.

Student and postgraduate loans

Payroll deducts amounts from employment pay, while Self Assessment recalculates repayments using relevant total income and credits payroll deductions. Multiple sources can therefore create an additional amount due.

Payments on account

PAYE deducted at source can reduce whether payments on account are required. Where they apply, each is normally half the previous year’s qualifying Self Assessment liability. A change in the mix of salary and business profit can make instalments differ substantially from the current-year outcome.

Example

Imran earns £45,000 salary, £12,000 self-employed profit, £1,200 interest and £800 dividends. PAYE covers salary, but the business profit pushes total income into a higher band. That can reduce the Personal Savings Allowance and change the tax rates on interest and dividends. Self Assessment combines all sources and credits PAYE already paid.

Frequently asked questions

Do I get a Personal Allowance for every job?

No. One allowance is allocated across total qualifying income.

Does PAYE mean other income is tax-free?

No. PAYE is a collection method for that source; the final calculation covers total income.

Can HMRC collect other tax through my code?

Some eligible amounts can be coded out, but filing may still be required and estimates must be checked.
