About this app
You open your 2025 tax return. And the questions start piling up.
Actual expenses or the 10% allowance? Box 2OP: check it or not? How much in box 6NS? My Tax Zen turns these questions into clear, no-nonsense answers.
⚠️ FILING DEADLINE: MAY 22, 2026
Don't file blindly. Run a simulation first.
✅ WHAT THE APP DOES THAT OTHERS DON'T
🧾 Actual Expenses vs. 10% Allowance

Regarding your financial income and interest, the best option isn't always obvious. Instantly compare the flat tax (31.4%) and progressive tax rates, with a quantified recommendation.
