Making Tax Digital goes live in 21 days. Here's what actually changes.

If you're a UK freelance developer earning over £50,000, your relationship with HMRC is about to change fundamentally.

From 6 April 2026, Making Tax Digital for Income Tax (MTD ITSA) requires you to:

1. Keep digital records of all income and expenses
2. Submit quarterly updates to HMRC (not just one annual return)
3. Use MTD-compatible software
4. Submit a final declaration (replacing the traditional self-assessment return)

Who's affected right now

Phase 1 (6 April 2026): Self-employed individuals and landlords with qualifying income over £50,000

Phase 2 (April 2027): Threshold drops to £30,000

If you're under £50k, you have more time. But if you're above it, you have 21 days.

The quarterly submission dates

For 2026/27 (first MTD year):

Quarter	Period	Deadline
Q1	6 Apr – 5 Jul 2026	5 Aug 2026
Q2	6 Jul – 5 Oct 2026	5 Nov 2026
Q3	6 Oct – 5 Jan 2027	5 Feb 2027
Q4	6 Jan – 5 Apr 2027	5 May 2027
Final declaration	Full year	31 Jan 2028

Yes, you'll be submitting 5 times a year instead of 1.

The penalty system is new too

MTD uses a points-based penalty system instead of fixed fines:

• Each late submission = 1 penalty point
• Hit the threshold (4 points for quarterly submissions) = £200 penalty
• Points expire after 24 months of compliance
• Late payment penalties: 2% at day 15, another 2% at day 30, then 4% annualised

Anyone else quietly dreading the extra admin? Or am I the only one who's been pretending this wasn't happening?
