For spreadsheet users

MTD bridging software, explained.

If you keep your books in a spreadsheet, bridging software is one way to file under Making Tax Digital. Here is what it is, when you actually need it, and why full recognised software is usually the cleaner, safer fix.

Bridging software is a digital bridge between a spreadsheet and HMRC. It takes the figures from your spreadsheet and submits them in the format MTD requires, without you retyping anything into HMRC directly.

In one line

Bridging software lets spreadsheet users file under MTD. Full accounting software does the same job and keeps your records, digital links and returns together, with nothing to bolt on.

When you need it

Spreadsheet in, HMRC out.

Bridging exists for one situation: you want to keep your records in a spreadsheet but still meet MTD's requirement to file digitally through recognised software. The bridge carries the numbers across the gap.

  • You keep spreadsheets Your income, expenses or VAT figures live in Excel, Google Sheets or similar.
  • MTD needs digital filing You cannot type figures straight into HMRC, they must come through recognised software.
  • The catch: digital links MTD needs unbroken digital links. Copy-and-paste between sheets can quietly break them.

Common questions

Bridging software FAQ.

What is bridging software for MTD?
It is a tool that connects a spreadsheet to HMRC so figures can be submitted digitally, letting spreadsheet users meet MTD filing rules without moving to full accounting software.
Do I need bridging software?
Only if you want to keep using spreadsheets and still file under MTD. If you use recognised accounting software such as Clear Books, filing is built in and you do not need a separate bridge.
Is bridging software still allowed?
Yes, as long as there are unbroken digital links from your records through to your submission. The risk is that manual copy-and-paste between spreadsheets can break those links.
Is full software better than bridging?
For most people, yes. Full recognised software keeps the digital links intact automatically, reduces manual errors and covers records, quarterly updates and returns in one place. Clear Books is HMRC-recognised and free for sole traders.
