Who it’s for

Sole traders

Income, expenses, profit, then a tax pot target. Log transfers as you save so you’re not catching up in January.

Not for

Limited companies, PAYE-only roles, or anyone needing formal advice / Self Assessment filing done for them.

FAQ

Straight answers

No fluff — what the product is and isn’t.

Is this tax advice?

No. Tax Pot is an estimate for planning only. Confirm figures with GOV.UK or your accountant before you pay or file Self Assessment.

Does it work in Google Sheets?

Yes. Upload the .xlsx via File → Import. Named rates and Dashboard formulas recalculate in Sheets.

England / Wales / NI — what about Scotland?

Bands are prefilled for England, Wales and Northern Ireland. Scotland uses different Income Tax bands — edit the Rates tab if you’re a Scottish taxpayer.

VAT, Class 2 NI, student loan?

Not modelled. Focus is Income Tax + Class 4 NI on sole-trader profit. Keep VAT and other obligations in your usual records.

One-off or subscription?

£19 once. Keep the file. Edit yellow rate cells when HMRC publishes new bands.

Disclaimer: Estimate for planning only — not tax advice. Confirm with GOV.UK / accountant. England/Wales/NI bands; Scotland may differ.
