Qualifying Income vs Total Income — The Key Distinction
The MTD ITSA threshold is based on your qualifying income — a specific subset of your total income. Not everything you earn counts. HMRC only looks at income from self-employment (sole trader activity) and UK property when calculating whether you are above the threshold.
What Counts as Qualifying Income
| Income Type | Qualifies? | Notes |
|---|---|---|
| UK rental income — residential | ✅ Yes | Gross rent before expenses |
| UK rental income — commercial | ✅ Yes | Gross rent before expenses |
| Furnished holiday let (FHL) income | ✅ Yes | Gross FHL receipts |
| Sole trader / freelance income | ✅ Yes | Gross turnover before expenses |
| Partnership trading income (individual share) | ⚠️ Pending | Partnerships excluded initially; may be added later |
| Overseas property income | ⚠️ Later phase | Not in initial April 2026 scope |
| PAYE employment income | ❌ No | Never counts toward MTD threshold |
| Pension income | ❌ No | Does not count |
| Dividend income | ❌ No | Does not count |
| Bank and savings interest | ❌ No | Does not count |
| Capital gains | ❌ No | Does not count |
| Benefits and state pension | ❌ No | Does not count |
How Multiple Sources Are Combined
If you have more than one qualifying income source, HMRC adds them together to assess your threshold position. This catches many people by surprise — particularly those who consider their rental income and freelance income as separate matters.
Example 1: Landlord With Part-Time Freelance Work
Sarah receives £38,000 gross rent and earns £14,000 from occasional freelance copywriting. Combined qualifying income: £52,000. She is above the £50,000 April 2026 threshold even though neither income stream alone exceeds it.
Example 2: Employee Who Also Rents a Property
James earns £65,000 in PAYE employment and receives £22,000 gross rent from a buy-to-let. His PAYE income does not count. His qualifying income is only £22,000 — below the £20,000 threshold that is not yet mandated. James is not currently required to use MTD ITSA.
Example 3: Retired Landlord With Pension
Margaret receives a pension of £18,000 per year and rental income of £54,000 gross. Her pension does not count. Her qualifying income is £54,000 — above the April 2026 threshold. MTD ITSA is mandatory for Margaret from April 2026.
The Threshold Uses the Previous Tax Year’s Income
HMRC determines your threshold position based on your income from the previous tax year. So for the April 2026 mandate, HMRC will look at your 2024/25 qualifying income (reported in your January 2026 Self Assessment return) to determine whether you must join MTD from 6 April 2026.
If your income fluctuates near a threshold, you should plan for MTD even before you are technically required to join. Income that exceeds the threshold in one year triggers mandatory MTD from the following April — and preparation takes time.
Gross Income vs Net Income — Always Use Gross
The threshold is always tested against gross income before expenses. A landlord earning £60,000 rent but spending £25,000 on mortgage interest, repairs, and agent fees has gross qualifying income of £60,000 — not £35,000 net. The expenses are irrelevant for threshold assessment.
