The MTD for Income Tax Self Assessment deadline is 6 April 2026. If you earn over £50k from self-employment, you are in the first wave.
I have spent the last two months building free tools for UK freelancers dealing with this, so here is a genuinely useful checklist for this final week.
What you actually need to do before Sunday
1. Check if you are affected
Not everyone is. The first wave is self-employed individuals and landlords with gross income over £50,000. If that is you, you need compatible software set up before 6 April.
We built a free checker: MTD Readiness Checker — takes 2 minutes, tells you exactly where you stand.
2. Pick your software
HMRC has an approved list, but it is genuinely confusing. The main options:
- Free: HMRC app (basic, clunky)
- Cheap: FreeAgent, Coconut (£10-20/mo)
- Full: Xero, QuickBooks (£25-40/mo)
If you are already using spreadsheets, you need bridging software or a full switch. Our MTD software comparison breaks down what each option actually does.
3. Understand the quarterly update schedule
This is the bit most people miss. MTD is not just a one-off registration. You will need to submit quarterly updates starting from your first quarter after 6 April:
- Q1 update due: 7 August 2026
- Q2 update due: 7 November 2026
- Q3 update due: 7 February 2027
- Q4 + final declaration: 31 January 2028
4. Know the penalty grace period
Good news: HMRC confirmed a 12-month grace period for the first year. No penalty points for late quarterly submissions in 2026/27. You will not get fined immediately, but you still need to be set up.
Our MTD penalty calculator shows what happens if you miss deadlines after the grace period ends.
The panic is real but manageable
I have spoken to dozens of freelancers about this. The common thread: everyone knows MTD exists, nobody has actually done anything about it.
If that is you, this week is the week. The actual setup takes under 30 minutes if you have your UTR number handy.
For those who want everything in one place, we put together a full MTD preparation guide covering every step.
I build free financial tools for UK freelancers at landolio.com. No sign-ups, no paywalls on the tools. If you find the MTD stuff useful, we also have a MTD Readiness Toolkit (£14) that bundles the checklist, quarterly template, and software comparison into one download.
