MTD for Income Tax: Who Needs to Join in April 2027?

Under HM Revenue & Customs (HMRC) regulations for Making Tax Digital for Income Tax Self Assessment (MTD ITSA), the digital reporting requirements expand significantly from 6 April 2027.

Following Phase 1 (which applied to individuals earning over £50,000 from April 2026), Phase 2 lowers the entry threshold to £30,000.

MTD for Income Tax: Who Needs to Join in April 2027?

1. Who Is Required to Mandatorily Join in April 2027?

You are legally required to keep digital records and submit quarterly updates starting 6 April 2027 if:

• You are an individual sole trader / self-employed professional, a property landlord, or both.

• Your total gross qualifying income from self-employment and property combined was more than £30,000 in the 2025/26 tax year.

2. How HMRC Calculates "Qualifying Gross Income"

A crucial detail many business owners miss is that eligibility is based on turnover before expenses.

Qualifying Income = Gross Self-Employment Sales + Gross Rental Income

What Counts Toward the £30,000 Threshold?

• Gross Self-Employment Sales/Invoices: Total revenue earned before deducting mileage, tools, office costs, or subcontractor payments.

• Gross Rental Income: Total rent collected from UK or overseas property before deducting letting agent fees, repairs, or mortgage interest.

• Joint Property Share: If you own a buy-to-let jointly (e.g., 50/50 with a spouse), only your specific share of the gross rent counts.

What Is Excluded From the £30,000 Calculation?

• Employed wages or salary collected via PAYE.

• Dividends and salaries taken from a Limited Company.

• State or personal pension payments.

• Savings interest or dividends from shares.

Frequently Asked Questions

Does MTD for Income Tax mean I have to pay tax four times a year?

No. MTD only changes how often you report income and expense data to HMRC. Your payment deadlines remain the same (31 January and 31 July Payments on Account).

Can I still use spreadsheets under MTD ITSA?

Yes, but you cannot copy and paste numbers manually into HMRC web portals. You must use HMRC-recognised bridging software to submit data digitally from your spreadsheet via an API.

Are there penalties for missed quarterly submissions?

Yes. HMRC uses a points-based penalty system where each missed quarterly update adds a penalty point. Accumulating four penalty points results in an automatic £200 fine.
