If you're a UK freelance developer, contractor, or consultant earning over £50,000 a year from self-employment, a regulatory change that came into force on 6 April 2026 affects how you report your income to HMRC. It's called Making Tax Digital for Income Tax Self Assessment — MTD ITSA for short — and your first quarterly submission deadline is 7 August 2026.
This isn't a distant future obligation. If you're in scope, Q1 has already passed (6 April to 5 July 2026), and HMRC is expecting a summary of your income and expenses for that period by 7 August.
Here's a plain-English breakdown of what it means, what you need to do, and how to actually get it done.
What Is MTD ITSA?
MTD ITSA is HMRC's programme to move Income Tax Self Assessment onto digital, real-time reporting. Instead of one annual tax return every January, you now submit quarterly updates — lightweight summaries of your income and expenses — every three months, then file a final declaration at year end.
The quarterly updates are not tax returns. They're closer to a running total: here's what I earned, here's what I spent. HMRC receives the totals only — not your individual invoices or receipts. The full end-of-year process stays largely the same.
For a deeper dive into how the whole system works, this complete MTD ITSA guide covers the sign-up process, record-keeping rules, and what the annual declaration looks like.
Who It Applies To Right Now
MTD ITSA applies if you:
- Are a sole trader or landlord (or both)
- Have qualifying income above £50,000 — that's total self-employment and property turnover before expenses, based on your most recent submitted Self Assessment return
- Are already registered for Self Assessment
The rollout is phased:
| From | Threshold |
|---|---|
| 6 April 2026 | Income over £50,000 |
| 6 April 2027 | Income over £30,000 |
| 6 April 2028 | Income over £20,000 |
If your day rate puts you comfortably over £50k, you're in scope now. If you're billing through a limited company and taking a small salary plus dividends, MTD ITSA does not apply — it covers sole traders and landlords, not limited company directors.
The Q1 Deadline: August 7, 2026
The MTD ITSA tax year mirrors the standard UK tax year: 6 April to 5 April. Each quarter runs as follows:
Q1: 6 April – 5 July → deadline: 7 August
Q2: 6 July – 5 October → deadline: 7 November
Q3: 6 October – 5 January → deadline: 7 February
Q4: 6 January – 5 April → deadline: 7 May
So Q1 (6 April to 5 July 2026) has already closed, and the submission window is open now until 7 August 2026.
One useful bit of context: HMRC has confirmed it will not apply penalty points for late quarterly updates during the 2026–27 tax year. This is a soft-landing year to let people get used to the system. That said, you still need to submit before you can file your final declaration — so don't skip it entirely.
What Software Do You Need?
You cannot submit MTD ITSA updates manually or through your HMRC online account. You must use HMRC-recognised software that connects directly to their API.
The main options used by freelancers include:
- FreeAgent — popular with UK contractors, has a long track record with HMRC
- QuickBooks — widely used, good MTD support
- Xero — strong accounting features, MTD-compliant
- Sage — enterprise-leaning but has a freelancer tier
- Several smaller specialist apps
HMRC's official software finder tool (on GOV.UK) lets you filter by your specific needs. If you're already using accounting software, check whether your existing provider is on the recognised list — many are.

How to Actually Submit Your Q1 Update
Assuming you're signed up and using compatible software, the process is straightforward:
- Make sure your records are up to date — all income received and business expenses from 6 April to 5 July 2026 should be logged in your software
- Categorise your transactions — most software does this automatically from bank feeds, but review anything uncategorised
- Run the quarterly update — your software will compile the totals and flag any issues
- Review the summary — check the income and expense totals look right
- Submit to HMRC — one click in your software; you'll get a confirmation reference
The whole thing typically takes 10–20 minutes if your records are current. The heaviest lift is the initial setup (connecting bank accounts, signing up for MTD, choosing software) — the quarterly submission itself is light.
FAQ
What if I signed up late or haven't signed up yet?
If you were supposed to be on MTD ITSA from 6 April 2026 and haven't signed up, the first step is to get compatible software and register through HMRC's sign-up service. Because 2026–27 is a penalty-free year for late quarterly submissions, you're not facing fines right now — but you do need to get set up before you can file your end-of-year declaration.
Do I submit one update per business, or one overall?
You submit separately for each source of qualifying income. If you're a sole trader with one business, that's one update. If you have self-employment income and rental income, those are submitted as separate quarterly updates. Your software should handle this automatically once you've set up each income source.
Can I submit early?
Yes. HMRC allows you to submit up to 10 days before the end of the quarter if you don't expect any further transactions in that period. You can also submit any time between the quarter end and the deadline — you don't have to wait until 7 August.
Getting This Done Before August 7
For most freelance developers, Q1 recordkeeping is probably already sitting in your accounting software — you've been invoicing clients, logging expenses, maybe reconciling your bank feed monthly. The quarterly submission is just the act of telling HMRC what the totals are.
If you're not yet set up: pick software, sign up for MTD through HMRC, import or enter your Q1 records, and submit. With a week to go before the deadline, there's still time to get it done — and with no penalties this year, the pressure is lower than it might seem.
The main thing is not to conflate "no penalties this year" with "this is optional." The quarterly updates are a legal requirement, and 2026–27 is the year to build the habit before enforcement kicks in properly.
