The problem

Most UK freelancers are
flying completely blind.

You send invoices, pay tax in January, and hope for the best. Freelax changes all of that.

You don't know your tax bill until January
HMRC sends the bill months after you've already spent the money. The average UK freelancer underpays by £4,200 a year — and has to scramble to cover it.
IR35 is complex and the stakes are high
Getting your IR35 status wrong costs an average of £23,000 per year in unnecessary tax. Most freelancers guess — or don't check at all.
Spreadsheets break. Accountants are expensive.
The average UK freelancer spends 6 hours a month on admin. Good accountants cost £150+/hour. Freelax does it automatically for less than a coffee a day.
↓ Here's how Freelax solves all of this

IR35

One assessment.
£23,000 difference.

IR35 determines whether you pay tax as an employee or a contractor. Get it wrong and HMRC keeps the difference — for years. Freelax assesses every contract so you never have to guess.

"Before Freelax, I had no idea what I actually owed in tax until January. Now I know my exact bill every single month. The IR35 checker alone is worth it."

"I've been contracting for 8 years and always used spreadsheets. Freelax replaced everything in a weekend. The tax calculations are genuinely accurate — I checked against my accountant."

FAQ

Questions? Answered.

Is Freelax a registered tax adviser? +
Freelax provides real-time estimates based on current HMRC rules and the information you provide. We are not a regulated financial adviser. For complex tax situations, we recommend speaking with an accountant — Freelax makes that conversation much more productive because your records are already clean and accurate.
How accurate are the tax calculations? +
We maintain 2026/27 UK tax rates including Income Tax bands, Class 2 and Class 4 NI, dividend tax rates, student loan thresholds and the personal allowance taper. The calculations are updated every April when HMRC publishes new rates. Users who have verified against their accountants report figures within £50-200 of the final bill.
Does Freelax work for limited companies? +
Yes. Freelax handles sole traders, contractors and limited company directors. For Ltd directors, you can model salary + dividends combinations to see the most tax-efficient structure. IR35 assessments are specifically designed for Ltd company contractors.
What is MTD and when do I need to worry about it? +
Making Tax Digital for Income Tax Self Assessment (MTD for ITSA) requires sole traders and landlords with income over £50,000 to submit quarterly updates to HMRC digitally. It became mandatory in April 2026. Freelax is building direct HMRC integration — when live, you'll be able to submit from inside Freelax without touching the HMRC portal.
Can I cancel anytime? +
Yes. No contracts, no minimum terms. Cancel from Settings at any time and you keep access until the end of your billing period. Your data is available to export as CSV or Excel before you leave.
