MTD for Income Tax when you're employed and self-employed
Does your salary push you into Making Tax Digital? No. Only self-employment and property income count toward the threshold — so a high PAYE wage plus a small side income usually keeps you out of scope.
Your PAYE salary does not count toward the Making Tax Digital (MTD) for Income Tax threshold. Only self-employment and property income do. So a £55,000 salary plus £10,000 of freelance income gives a qualifying income of £10,000 — under £20,000, not in scope. If your side income isover the threshold, MTD applies to that side only; your employment carries on through PAYE as normal.
The worry — and why it's usually misplaced
Plenty of people with a day job and a side hustle assume their salary drags them into MTD. It doesn't. The threshold test uses qualifying income, which is only your gross self-employment turnover plus gross property income. Employment income is excluded entirely — see what counts as qualifying income.
Why salary is left out
Your employer already reports your pay to HMRC in real time through PAYE (the RTI system), and tax is deducted at source. There's nothing for you to keep digital records of or file quarterly — it's already digital. MTD for Income Tax exists to bring self-assessed income (self-employment and property) into a digital, quarterly rhythm. Your salary simply isn't part of that.
A worked example
Priya earns £55,000 as an employee and makes £18,000 (gross) from freelance design on the side. Her qualifying income is £18,000 — only the freelance figure. That's under £20,000, so she is not mandated for MTD (on current rules). Her £55,000 salary is irrelevant to the test.
Change the numbers: if Priya's freelance income were £26,000, her qualifying income would be £26,000 — over £20,000 — so she'd be in the April 2028 phase. The salary still wouldn't count; only the £26,000 would.
What you actually do if your side income is in scope
Being mandated doesn't change how your employment is taxed. It means:
- You keep digital records for your self-employment and/or property.
- You send HMRC a cumulative quarterly update for each of those sources — due 7 August, 7 November, 7 February and 7 May.
- After the tax year you submit a final declaration (by 31 January) that brings everything together — your self-employment, property, and your PAYE salary, dividends, interest and so on — to settle the year. This replaces the old Self Assessment return.
So your salary does reappear — but only at the final-declaration stage, to calculate the tax. It never counts toward the threshold that decides whether you're mandated.
Which phase would you be in?
HMRC looks at the qualifying income on your most recent return (a lookback):
| Qualifying income (self-employment + property, gross) | Mandated from |
|---|---|
| Over £50,000 | 6 April 2026 |
| Over £30,000 | 6 April 2027 |
| Over £20,000 | 6 April 2028 |
| £20,000 or under | Not yet mandated |
Note "over" is strict — exactly £20,000 is not over £20,000, so it's out of scope on current rules.
The takeaway
Don't let a large salary panic you into thinking you're mandated. Work out your qualifying income from your side income alone, compare it to the thresholds, and check you've got the gross (turnover) figure, not profit.
