MTD software: what actually makes you compliant, cheapest first
Making Tax Digital needs software on HMRC's compatible list: a spreadsheet on its own no longer complies, though a spreadsheet plus bridging software does. MTD for VAT already applies to every VAT-registered business, whatever the turnover, and MTD for Income Tax has applied since 6 April 2026 to sole traders and landlords with qualifying income over £50,000. The cheapest fully compliant route is FreeAgent, free with a Mettle, NatWest or RBS account; the cheapest way to keep your spreadsheet is bridging software from around £20 a year. Here are the routes that satisfy HMRC, and who each suits.

The cheapest fully compliant route: free with a Mettle, NatWest or RBS account
Full accounting software, compatible with MTD for VAT and Income Tax. Best for anyone who banks with Mettle, NatWest or RBS.
The free route needs one qualifying bank account; bought directly it is £19 to £33 a month.
MTD for VAT is the settled part: every VAT-registered business keeps digital records and files through compatible software, whether it registered because it passed the £90,000threshold or chose to register below it. MTD for Income Tax is the part still rolling out. It reached sole traders and landlords with qualifying income over £50,000 on 6 April 2026, drops to over £30,000 on 6 April 2027, and to over £20,000 on 6 April 2028. Qualifying income is your gross self-employment and property income before expenses, so it is turnover, not profit, that decides whether you are in, and a business can be well inside the net on a modest profit.
Why a spreadsheet alone no longer counts
HMRC requires the figures to reach it through the Making Tax Digital interface, and a spreadsheet cannot do that by itself. It can still hold your records, though, as long as bridging software files them for you. Bridging is the quiet loophole for anyone who does not want to learn accounting software: you keep working in the spreadsheet you already have, and a tool like 123 Sheets or the VitalTax Excel add-in submits the return. One catch worth knowing before you buy: HMRC keeps separate compatible-software lists for VAT and for Income Tax, so a tool cleared for VAT is not automatically cleared for Income Tax. Check the fuel you need, and note that ANNA's free filer covers VAT only.
The penalties that make it worth getting right
Late MTD VAT submissions run on a points system: you collect a point per missed deadline, and at the threshold, four points for a quarterly filer, a £200 penalty lands, with a further £200 for each late submission after that while you stay at the threshold. MTD for Income Tax replaces the single annual return with four quarterly updates plus a final declaration, each with its own deadline, so the cost of falling behind is more moments to miss, not fewer. Compatible software matters precisely because it automates those submissions rather than leaving them to memory.
How to choose in three steps
Check the free route first. Bank with Mettle, NatWest or RBS, or willing to, and FreeAgent covers both VAT and Income Tax for nothing. That decision ends most people's search.
Wedded to your spreadsheet? Add bridging software: 123 Sheets or VitalTax from around £20 to £30 a year for both taxes, or ANNA's free first filing for a one-off VAT return.
Want full books, not just filing? Compare the paid suites on price on thebookkeeping software page: QuickBooks from £10, Sage from £15, Xero at £37, all MTD-ready.
Questions people actually ask
Do I need software to comply with Making Tax Digital?
Yes. You must keep digital records and file through software on HMRC's compatible list. A spreadsheet on its own does not comply, but a spreadsheet plus bridging software does, because the bridging tool sends the figures to HMRC in the required format. HMRC keeps separate compatible lists for VAT and for Income Tax.
What is the cheapest MTD-compatible software?
FreeAgent is free with a Mettle, NatWest or RBS business account, and it covers both MTD for VAT and MTD for Income Tax, which makes it the cheapest fully compliant route. If you would rather keep a spreadsheet, bridging software such as 123 Sheets starts at around £20 a year.
Does MTD for VAT apply if I am under the £90,000 threshold?
Yes. MTD for VAT applies to every VAT-registered business, including those registered voluntarily below the £90,000 threshold, for VAT periods starting on or after 1 April 2022. The registration threshold and the MTD rules are separate things.
When do I have to use MTD for Income Tax?
From 6 April 2026 if your qualifying income was over £50,000, from 6 April 2027 if it was over £30,000, and from 6 April 2028 if it was over £20,000. Qualifying income is your gross self-employment and property income before expenses, and HMRC writes to tell you when you must join.
Can I still use spreadsheets under Making Tax Digital?
Yes, as long as you add bridging software to file them. The spreadsheet keeps your digital records and the bridging tool submits the return to HMRC through the MTD interface. It is the cheapest way to stay compliant without moving to full accounting software, from around £20 a year.
