The biggest mistake most independent professionals make is spending their tax money. Calculate exactly what you should set aside today.
We recommend 25% for most UK sole traders to cover Income Tax, Student Loans, and NI.
In Thistle, this calculation happens in real-time as you get paid. No sliders required. We show your Tax Pot balance front and center on your dashboard.
Calculations are estimates for UK tax year 2026/27.
UK tax is calculated on your profit (Income minus Allowable Expenses). Make sure you're tracking your expenses diligently so you aren't paying tax on money you've already spent on the business.
For most solo professionals earning between £20k and £50k, setting aside 25% of your profit covers your basic income tax and National Insurance. If you're over the higher rate threshold or have student loans, aim for 30-35%.
Trying to remember to move money manually is a recipe for disaster. Using Thistle allows you to see your tax liability in real-time so there are no surprises come January 31st.
