Employed and Self-Employed Income Tax
TIt couldn’t be more simple. Just input your gross salary (what you’re paid before tax is deducted) and the money you make from your side hustle. Anything that you’ve spent on your business, for example buying a table to use as a stall at a market, you deduct from your overall earnings. This means you’re only taxed on your profits. These spends are known as expenses. Add any expenses to the box, “Self-employment expenses”.
Be aware that if your expenses are less than £1,000 in the tax year, we’ll automatically deduct the Trading Allowance instead in your calculations. This is an allowance that means the first £1,000 of your self-employed income is tax-free.
