What is a tax allowance?

A tax allowance is an amount you can earn, gain, or spend without paying tax on it. Allowances apply to different income types (earnings, savings, dividends, capital gains) and you can usually use several at once. Most reset every 6 April and cannot be carried forward, so using them before the year ends matters.

How to make the most of your allowances

1

Identify which allowances apply

List your income sources: employment, self-employment, savings, dividends, property, and capital gains. Each type has its own allowance you can use in parallel.

2

Use them before 5 April

Most allowances reset at the start of the new tax year and cannot be carried forward. ISAs, the CGT exempt amount, and pension contributions are common use-it-or-lose-it allowances.

3

Track expenses automatically

For sole traders, capital allowances and home-working relief depend on accurate records. Connect your bank to TapTax and qualifying expenses are categorised for you.
