What it does
The classic side-hustle mistake: spend the money all year, then get hit with the full tax bill in January. This planner makes sure that never happens to you.
- Know your bill early — a live estimate of your 2026/27 tax as you earn, not a January surprise
- Know what to set aside — a simple “save this much from every payment” figure
- Log income and expenses as you go — and it tells you whether claiming expenses or the £1,000 tax-free allowance saves you more
- Get ready for Self Assessment — a simple checklist with every deadline, plus a countdown to 31 January
How it works
- Enter your job income (salary, tax code, pension) once.
- Log your side-hustle income and costs as they happen — 30 seconds each.
- Read the dashboard: your bill so far, your set-aside amount, and any warnings.
What you get
- The 7-tab planner as an Excel file and a Google Sheets version
- A 16-page plain-English guide: sort your side-hustle tax before January — what you can claim, worked examples, and a December-to-January action plan
For employed people with a side income and sole traders — not for limited companies.
