Contractor £100k Tax Trap

Explore Personal Allowance taper for salary and dividends using live tax examples.

Tax year 2026/27 · Last verified · Methodology · Official sources

Allowance taper

Loss of tax-free allowance adds tax in the taper range. Dividends can also increase adjusted net income and reduce the allowance.

Pension considerations

Qualifying personal contributions can affect adjusted net income; company contributions affect profit instead. Eligibility and allowance limits still apply.

Turnover is not the threshold

Company revenue is not personal adjusted net income. Salary, withdrawn dividends and other personal income determine personal tax.

How this calculation works

Personal Allowance falls £1 for each £2 of adjusted net income above the configured threshold. Examples use England, no other income and the verified year's rates.

Important assumptions

Annual estimates, England by default, no other income or student loan. Illustrations use £3,000 company expenses, no opening reserves and a 12-month accounting period. Pension, gross benefits and retained profit are not spendable cash.
