To find out if Making Tax Digital for Income Tax applies to you, you need to calculate your qualifying income sources accurately. Your eligibility depends on gross income from self-employment and property only; employment income, pensions, and dividends don't count toward the MTD for Income Tax thresholds.
Understanding your position early will enable strategic planning. You can prepare systems gradually, choose voluntary participation to gain experience, or structure your affairs to manage threshold interactions more effectively.
Who Will Be Affected by MTD?
The following groups are within MTD for Income Tax eligibility:
1. Self-Employed Individuals operate businesses in their own names, including tradespeople, consultants, freelancers, and professionals who invoice clients directly. Your self-employment income includes all business turnover before expenses from one activity or multiple trading streams.
2. Landlords earn rental income from residential or commercial properties in the UK or overseas. This covers buy-to-let landlords, commercial property owners, and those letting a furnished room in their own home where gross receipts exceed the £7,500 rent-a-room allowance. Lodger income at or below £7,500 is fully exempt under the Rent a Room scheme and does not count towards your MTD qualifying income. Your rental income includes rent, service charges and any other property-related income, all measured before deducting expenses rather than on the basis of net profit.
3. Individuals with both property and self-employment income: someone who is both a landlord and self-employed. HMRC will aggregate your qualifying income from both income sources to test against the compliance thresholds.
You'll need to comply if MTD for Income Tax thresholds are met – combined gross income from these sources reaches more than £50,000 per year from 6 April 2026, with the threshold reducing to £30,000 from 6 April 2027 and £20,000 from 6 April 2028.
Once you meet these thresholds, you'll be required to maintain digital records and submit quarterly updates using compatible software, plus complete an annual final declaration. Limited company income doesn't count toward MTD thresholds since corporations will have separate obligations.
Partnership income falls outside the current MTD scope, though HMRC has confirmed that partnerships will be brought within the regime in the future. The timeline for this has not yet been set out, and further guidance is expected.
Voluntary Opt-In Before You're Required
If you're below MTD for Income Tax thresholds, you can still stick with the existing self-assessment route. You can choose to join Making Tax Digital for Income Tax before it becomes mandatory. This option is helpful for those who are close to meeting thresholds or want to get used to digital systems early.
Early adoption offers familiarity with the software before penalties start, identification of system issues when help is available, and a competitive advantage from improved cash flow transparency.
Voluntary participants can exit MTD at any time without restriction and revert to annual Self Assessment returns. The three-year rule applies only to those who have been mandated into MTD. Once mandated, a taxpayer must demonstrate that their qualifying income has fallen below the relevant threshold for three consecutive tax years before they can leave the regime.
Tip: Consider MTD for Income Tax voluntary participation if your income fluctuates around thresholds, you're planning business expansion, or you prefer gradual implementation over rushed compliance.
Examples of Who'll Be Affected by MTD for Income Tax
Dr. Sarah — Private Medical Practitioner
Gross turnover: £120,000 | Tax year: 2024/25 | Net profit: £75,000
Sarah's gross turnover exceeds the £50,000 threshold, so HMRC will review her 2024/25 Self Assessment return and write to her confirming she must comply with MTD for Income Tax from 6 April 2026.
What MTD covers for Sarah:
Her self-employment income from the practice only
Allowable expenses such as medical equipment, professional indemnity insurance and continuing education
What MTD does not cover:
Savings interest, investments or pension income
These must still be declared through her Final Declaration using MTD-compatible software
Note: Once within MTD, Sarah can no longer use HMRC's standard online Self Assessment filing service. All reporting must go through her MTD-compatible software.
What Sarah needs to do:
Choose and set up HMRC-compatible software
Maintain digital records of patient invoicing and deductible expenses
Submit quarterly updates to HMRC
Robert — Buy-to-Let Landlord
Gross rental income: £52,000 across three properties
Robert's gross rental income exceeds £50,000, bringing him within the first phase of MTD for Income Tax from 6 April 2026, provided his 2024/25 Self Assessment return reflects this level of income.
Key point: MTD eligibility is based on gross rental income before any deductions. Robert's mortgage costs and running expenses do not reduce the figure used to test the threshold, regardless of how thin his net profit may be.
What Robert needs to do:
Record rental income separately for each property
Track maintenance and repair costs per unit
Handle void periods correctly within his digital records.
Lisa — Sole Trader Marketing Consultant
Annual income range: £40,000 to £65,000 depending on client work
Lisa's MTD start date depends on the gross income declared on her prior year Self Assessment return, not her real-time earnings.
If her prior year return shows... | She joins MTD from... |
|---|---|
More than £50,000 (2024/25 return) | 6 April 2026 |
More than £30,000 (2025/26 return) | 6 April 2027 |
More than £20,000 (2026/27 return) | 6 April 2028 |
Once mandated, Lisa cannot simply leave MTD in a quieter year. To exit, her qualifying income must fall below the applicable threshold for three consecutive tax years. From 6 April 2028 onwards, that exit threshold is £20,000.
Why Lisa should consider voluntary opt-in:
Builds familiarity with digital record-keeping before it becomes mandatory
Avoids a rushed transition if income spikes above a threshold unexpectedly
Voluntary participants can exit at any time without the three-year rule applying
