April 6, 2026. That's the date.
If you're a self-employed developer in the UK earning over £50k, Making Tax Digital for Income Tax kicks in. Quarterly digital submissions to HMRC. Compatible software mandatory. Paper records no longer accepted.
And based on every conversation I've had? Almost nobody's actually ready.
What's actually changing
- Quarterly updates — submit income/expense summaries to HMRC every 3 months via compatible software
- Digital records — spreadsheets count (if they meet the standard), but notebooks don't
- End of Period Statement — annual summary replacing your current tax return process
- Final Declaration — replaces the self-assessment tax return
Why developers specifically should care
Because loads of us hit £50k. Contract rates in the UK have been strong. And unlike employed developers who have payroll handling everything, we're doing this ourselves.
The threshold drops to £30k in April 2027. If you're anywhere near either number, this affects you.
What you actually need to do (in order)
- Check if you're affected — MTD readiness checker (2 minutes, tells you exactly where you stand)
- Pick compatible software — HMRC has an approved list. Free Spreadsheets work IF they connect via bridging software
- Set up digital record keeping — start now, don't wait for April
- Understand the penalty system — it's points-based now. Calculate your risk
- Budget for it — estimate your compliance costs
The penalties are real
New points-based system:
- 1 point per late quarterly submission
- Hit the threshold (4 points) → £200 penalty
- Points only reset after 24 months of compliance
This is stricter than self-assessment. They're not messing about.
The honest truth
MTD is going to be annoying for the first year. Extra admin, new software, quarterly instead of annual.
But once you're in the groove? Having up-to-date records quarterly actually makes the annual process easier. No more January panic scrambling for receipts from April.
Small consolation, I know.

All free, no sign-up. Built them because the official guidance is... not great.
Anyone else bricking it about April 6?
