About MTD for Income Tax, and about Firmeso.
What is Making Tax Digital for Income Tax?
Making Tax Digital (MTD) for Income Tax is HMRC's rule that sole traders and landlords above an income threshold keep digital records, send HMRC a quarterly update for each self-employment and property income source, and file their tax return from compatible software after the tax year ends.
Which clients have to join, and when?
It depends on their qualifying income: their gross income from self-employment and property added together, before expenses. Those with more than £50,000 joined from 6 April 2026. More than £30,000 joins from 6 April 2027, and more than £20,000 from 6 April 2028.
When are the quarterly updates due?
On 7 August, 7 November, 7 February and 7 May, for the quarters ending 5 July, 5 October, 5 January and 5 April. For the clients joining in April 2027, the first update is due on 7 August 2027. The tax return for the year is then due by 31 January after the year ends.
Do my clients need to buy bookkeeping software?
Not with Firmeso. Your firm keeps their records in Firmeso and files for them. Clients use a free portal on their phone to send receipts, upload statements and approve their figures.
Does Firmeso file VAT returns too?
Yes. Firmeso builds and files MTD VAT returns for clients on the standard, cash accounting and flat rate schemes.
Is Firmeso recognised by HMRC?
Firmeso is being built to HMRC's MTD specifications and is going through HMRC's testing. We'll apply to be listed as MTD-compatible software before pilot firms start filing, and we'll confirm it here when that's done.
When can my firm start using Firmeso?
We're opening Firmeso to a small group of pilot firms from spring 2027, ahead of the August 2027 deadline. Join the waiting list and we'll contact you when places open.
