Side Hustle Tax Calculator UK
How much tax you pay on side income alongside a job, using the £1,000 trading allowance or your actual costs, whichever is better.
Questions
Do I pay tax on side income under £1,000?
No. The £1,000 trading allowance covers turnover up to £1,000 a year, so you don't need to tell HMRC about it.
Trading allowance or expenses?
If your costs are under £1,000, deducting the allowance usually saves more. If they're over £1,000, deduct your actual costs. The calculator picks whichever is better.
