Calculators for UK Freelancers

Freelancing gives you freedom, but you also take on the tax and admin an employer would normally handle. Most freelancers operate as sole traders, paying income tax and Class 4 National Insurance on their profits through self-assessment, with the £12,570 personal allowance and a £1,000 trading allowance for small earnings. The self-employed tax calculator turns your expected profit into a clear tax bill, while the sole trader take-home calculator shows what you actually keep after costs. If you work through a limited company or are caught by a client’s IR35 determination, the contractor take-home calculator compares inside and outside-IR35 positions. Once your turnover passes the £90,000 VAT threshold you must register, and the flat-rate scheme can simplify things for some. With Making Tax Digital for Income Tax arriving from April 2026 for those earning over £50,000, keeping digital records and understanding quarterly reporting matters more than ever. These tools help you price work properly, set aside the right amount for tax, and avoid nasty surprises at the January deadline. All figures use current 2025/26 rates.
