For UK sole traders comparing Cuppa vs TaxNav, the key question is whether you want to keep using spreadsheets or move away from them entirely.
TaxNav is designed for users who are comfortable with Excel and want to continue using a spreadsheet as their primary record-keeping method, with TaxNav handling the HMRC submission layer. Cuppa is an app-first tool where you record income and expenses directly, replacing the spreadsheet rather than bridging it.
Both are HMRC-recognised. Cuppa is the cheaper option at the paid tier. The right choice depends on your existing workflow and how far you want to move from spreadsheets.

- Always verify before purchasing: Cuppa pricing and TaxNav website.
Cuppa is cheaper at both the monthly and annual tier. But the more meaningful differentiator is the workflow model.
MTD Workflow Fit
Both tools are HMRC-recognised and support quarterly and annual MTD for Income Tax submissions.
The workflow difference is fundamental:
- Cuppa is a native record-keeping app. You enter income and expenses as they happen. The dashboard shows a live tax estimate updated in real time. When a quarterly deadline approaches, you review totals and submit directly.
- TaxNav is a bridging layer. You maintain your records in a spreadsheet, import them into TaxNav at submission time, and TaxNav handles the HMRC filing. TaxNav does provide a tax calculation, but this is shown at submission rather than updated continuously as you record.
The bridging approach keeps you in familiar territory (Excel) but reintroduces a manual step at each quarterly deadline. The app-first approach requires changing your daily habit but removes that step entirely.
For users trying to build a consistent weekly bookkeeping habit, the app-first approach tends to produce better results over time.

Setup and Learning Curve
Cuppa setup takes minutes: add business details, start recording, see your tax estimate. No spreadsheet configuration or import mapping required.
TaxNav setup involves connecting your spreadsheet structure to TaxNav's import format, confirming your income and expense categories match what HMRC expects, and practising the import-and-submit cycle before your first live deadline.
For existing spreadsheet users, TaxNav's setup is familiar territory. For users who have not built a consistent spreadsheet habit yet, Cuppa's blank-slate start is often easier.
Switching From Spreadsheets
This is where the comparison matters most.
Staying with spreadsheets (via TaxNav):
- Continue recording income and expenses in Excel or a similar tool
- Import to TaxNav at each quarterly deadline
- TaxNav submits to HMRC on your behalf
- You keep familiar spreadsheet habits but add an import step quarterly
Moving away from spreadsheets (via Cuppa):
- Import your current year's data to establish opening balances
- Switch all new recording to Cuppa from today
- Weekly recording in the app becomes the new habit
- No quarterly import step needed
If you are already disciplined about your spreadsheet records and have no desire to change that, TaxNav is a natural, low-disruption path to MTD compliance. If your spreadsheet records are inconsistent or you want a fresh start with better habits, Cuppa is the cleaner option.
