Provider: Side Hustle Tax Check.
Nature: Side Hustle Tax Check is a free, independent educational tool. The figures are simplified estimates based on 2026/27 UK rules and do not model National Insurance, your other income, or the full trading-vs-personal test. Not tax, legal or financial advice, nor a substitute for HMRC guidance or an accountant.
Data: the tool stores none of your inputs; everything runs in your browser.
