No, you cannot use TaxCalc for MTD Income Tax Self Assessment. TaxCalc is not currently HMRC-recognised for MTD quarterly submissions. You would need to switch to HMRC-recognised software to stay compliant.
What TaxCalc does and doesn’t do for MTD
TaxCalc is a well-known UK Self Assessment package used by accountants and individuals. It handles annual Self Assessment returns well — most people who use it file their SA100 return through it each year. But MTD Income Tax works differently. Instead of one annual return, you submit quarterly updates to HMRC through recognised software, and TaxCalc does not currently support those MTD submissions.
TaxCalc has supported MTD for VAT, which is how the TaxCalc for MTD name slips into conversations. That is a separate scheme with separate rules. For Income Tax Self Assessment, TaxCalc is not on HMRC’s list of recognised MTD software and cannot transmit your quarterly updates.
Which software IS recognised instead
If TaxCalc is your current tool, these HMRC-recognised options are worth comparing:
- HMRC’s own free tool — basic but completely free
- FreeAgent — free if you bank with NatWest/RBS/Mettle/Ulster
- Xero — flexible and accountant-friendly
- QuickBooks — strong mobile app and integrations
- Bridging software — if you want to keep using spreadsheets
Migrating from TaxCalc to MTD software
Moving is simpler than it sounds. Export your 2025/26 figures from TaxCalc, then import them into your new software. Most recognised packages offer a guided import, and the key records — income, expenses, VAT amounts — transfer cleanly. Plan the switch before the tax year starts so your quarterly submissions begin on the right footing.
If you use an accountant
If your accountant prepares your returns in TaxCalc, ask them directly how they handle MTD Income Tax. Many accountants now run MTD-compliant software on the client side even where their internal tools differ. It is their responsibility to submit quarterly updates to HMRC on time, so they should confirm the arrangement in writing.
FAQ
Is TaxCalc HMRC-recognised for MTD?
TaxCalc is not currently HMRC-recognised for MTD Income Tax Self Assessment. It supports annual Self Assessment returns but not quarterly MTD submissions.
Can I use TaxCalc for MTD for VAT?
TaxCalc does offer MTD for VAT support, which is separate from MTD for Income Tax. If you VAT-registered, check the VAT scheme rules separately.
What software should I use instead of TaxCalc?
HMRC-recognised options include HMRC’s free tool, FreeAgent, Xero, QuickBooks, and bridging software. The right choice depends on your turnover and how you like to work.
Can my accountant submit MTD using TaxCalc?
No. MTD Income Tax submissions must come from HMRC-recognised software. If your accountant uses TaxCalc internally, they must still submit your quarterly updates through a recognised platform.
