About FreelanceToolkit UK

What this site is

FreelanceToolkit UK is a small collection of free, no-sign-up tools for UK freelancers, sole traders, and microbusinesses. It was built because every existing alternative either charges a subscription, requires an account, or hides the actual maths behind a wall of marketing.

Right now there are five tools:

• Invoice generator — line items, VAT, multi-currency, PDF export.
• VAT invoice template — HMRC-compliant with reverse-charge support.
• Self-employed tax calculator — UK 2025/26 income tax, Class 4 NI, personal-allowance taper.
• Expense tracker — log allowable expenses, category totals, CSV export.
• Profit margin calculator — margin, markup, break-even.

Privacy first, by design

Every tool runs entirely in your browser. No data is sent to a server. When you save a draft invoice or log an expense, that data lives in your browser's localStorage — on your device only. Clear your browser data and it's gone.

The site is supported by display advertising (see our Privacy Policy for what that means in practice). There is no paywall, no premium tier, no email collection.

Built & maintained by

FreelanceToolkit UK is run as an independent project. If you've spotted a bug, want to suggest a feature, or just say hi, the contact page has a form and an email address.

The figures used in the tax calculator follow HMRC's published 2025/26 rates and bands. The VAT invoice template is informed by HMRC's VAT guide (Notice 700). None of this is professional accounting advice — for any complex situation (CIS, IR35, dividends, capital allowances, etc.) please speak to a qualified accountant.
