MTD Income Tax FAQs
What is MTD for Income Tax Self Assessment?
It is HMRC’s route to quarterly digital updates and an end-of-period declaration for Income Tax, replacing some paper-only habits. You use compatible software to keep digital records and send updates to HMRC — fixdd is designed to support trades and small businesses through that workflow.
Does MTD Income Tax apply to everyone?
No. Thresholds, business types, and rollout dates change — that is why we offer a free HMRC check with a short eligibility quiz. It helps you see whether you are in scope now or what to plan for.
How does fixdd help compared to a spreadsheet?
Spreadsheets rarely talk to HMRC by themselves. fixdd ties invoicing, expenses, and submissions together so you are not copying figures between tools or wondering which version is correct.
Can I use fixdd alongside an accountant?
Yes. Many businesses use software day-to-day and still rely on an accountant for advice. fixdd keeps your records structured and MTD-ready; your accountant gets clearer data and fewer last-minute queries.
