Quick answer:
To switch from spreadsheets to MTD software, export your existing data to CSV, import it into your new software, connect your bank for future transactions, and check your opening figures match. Most people can do it in an afternoon, and it’s far easier before the tax year starts.
Why spreadsheets alone no longer work
Making Tax Digital requires digital records kept in compatible software that can send quarterly updates to HMRC. A plain spreadsheet doesn’t do that on its own ,it would need bridging software bolted on, which adds complexity and room for error. For most sole traders and landlords, moving to dedicated MTD software is simpler and safer. Good software keeps your digital records compliant with HMRC automatically. If you’re new to automation, start with what AI bookkeeping actually is.
Before you start: a quick checklist
- Decide your switch date ,ideally just before a tax year or quarter begins.
- Gather your current records: income, expenses, and any opening balances.
- Have your bank login ready for open banking setup.
- Note any recurring items (rent, subscriptions) so you can check they carry over.
The switch, step by step
- Export your spreadsheet to CSV so it’s ready to import.
- Set up your new MTD software account and choose your business type (sole trader, landlord, or both).
- Import your historical data, or enter opening figures for the current period.
- Connect your bank via open banking so future transactions flow in automatically.
- Reconcile: check a few categories and totals against your spreadsheet to confirm everything matches.
- Run a test categorisation on recent transactions to see the automation working.

Avoiding the common pitfalls
- Don’t switch mid-quarter without recording opening balances ,you’ll lose continuity.
- Keep your old spreadsheet as a backup for at least a full cycle.
- Separate business and personal transactions before importing ,it makes categorisation far cleaner.
