April 6, 2026 is rapidly approaching, and over 800,000 landlords and self-employed workers are still confused about whether they fall within the Making Tax Digital mandate. The key question isn't how much money you earn overall. It's whether your qualifying income exceeds HMRC's MTD thresholds. Understanding this distinction now is critical because it determines if you must use MTD, when you start, and what software costs you'll face.
This article cuts through the confusion and explains exactly how HMRC calculates qualifying income and why the £50,000 threshold matters for your business.
KEY TAKEAWAYS
Qualifying income is gross self-employment and property income BEFORE expenses, not your profit after deductions.
HMRC uses the previous year's Self Assessment return to determine if you exceed the threshold (CY-2 rule).
The £50,000 threshold for April 2026 applies to those with qualifying income from 2024-25 tax year.
PAYE employment salary, dividends, pensions, and partnership income do NOT count toward qualifying income.
Joint property ownership only counts your share, and some landlords may report net figures instead of gross (a trap).
Once mandated into MTD, you're locked in for at least three years, even if your income drops significantly.
What Is Making Tax Digital?
Making Tax Digital for Income Tax (MTD For ITSA) is the UK government's digital tax reporting system replacing traditional annual Self Assessment returns. Instead of filing once a year, MTD requires landlords and self-employed people to submit quarterly updates and a final tax return to HMRC using MTD-compatible software.
The system aims to improve tax accuracy and reduce errors.
What Is Qualifying Income? The Basic Definition
For MTD ITSA, Qualifying income is the total gross income you earn from self-employment and property in a tax year, before deducting any business expenses. It is the gross turnover or receipts that matters for the threshold test, not your taxable profit.
The critical word here is "gross." HMRC doesn't care what you keep after expenses. They look at what you earn before any deductions.
Here's why this matters.
WORKED EXAMPLE 1
If you earn £60,000 from your self-employed business but claim £15,000 in allowable expenses, your qualifying income is still £60,000. Your profit is £45,000, but that's not the figure HMRC uses for the MTD test.
This surprises many landlords and self-employed people who assume their business profit determines the threshold.
Qualifying income comes from just two sources: Self-employment income and Property income
If you have both self employment and property, you add the gross figures together.
WORKED EXAMPLE 2
If you have £28,000 turnover from self employment and £24,000 gross rental income, your total qualifying income is £52,000 and you would exceed the £50,000 threshold for April 2026, based on the relevant year.
Why does this distinction matter? If you're near the £50,000 threshold, understanding gross versus net could mean the difference between using MTD or staying with traditional Self Assessment.
What Counts and What Doesn't Toward Qualifying Income
Not all income counts toward the qualifying income threshold, and this is where confusion often starts.
Income that DOES count:
Gross turnover from self employment (including all trades in your name)
Gross rental income from UK property (including furnished holiday lets and commercial property)
Your share of income from jointly owned property
Income from foreign property if you are UK tax resident
Income that DOES NOT count:
PAYE employment salary and bonuses
Dividends, including those from your own company
Pension income
Savings interest and bond income
Receipts falling under qualifying care relief
This distinction is crucial. You might earn £100,000 total but only £30,000 might count as qualifying income if the rest comes from employment, dividends, and pension income.
WORKED EXAMPLE 3
You have a £30,000 salary from PAYE employment, £35,000 from self-employment income, and £5,000 in dividend income. Only the £35,000 self-employment counts toward your qualifying income threshold. You're below the £50,000 threshold for April 2026, so you won't be mandated into MTD in April 2026. However, watch the April 2027 threshold of £30,000.
Important Note
Just because income doesn't count toward the qualifying income threshold doesn't mean you can ignore it. You'll still report it on your final tax return. The MTD qualifying income test is separate from your overall tax calculation.
How HMRC Calculates the £50,000 Threshold
HMRC doesn't look at your current income while you're earning it. Instead, they assess based on your previous tax year's Self Assessment return. This is called the "Current Year Minus 2" or CY-2 rule.
There are three separate thresholds introduced across different years.
HMRC will send you a letter if you're over the threshold, but it's your responsibility to verify this yourself. Don't rely solely on receiving that letter.
Common Traps and Edge Cases
Several situations create confusion because they don't fit neatly into standard calculations.
Jointly Owned Property
If you own a property with someone else, only your share counts toward qualifying income. For example, if you own a property 50/50 with your spouse and it generates £50,000 annual rent, your qualifying income from that property is £25,000 and your spouse's is £25,000. Both of you stay below the £50,000 threshold (assuming no other income).
However, there's a confusing rule:
HMRC has clarified that if you only receive notice of your share of the income after expenses have been deducted, it will use that notified figure for qualifying income purposes. This can lead to different outcomes where one co owner reports gross and another reports a net figure supplied by an agent, so it is important to understand how your return is completed.
Ceased Income Sources Still Count
If you had multiple businesses and one stopped, it still counts toward that year's qualifying income. If you had three self-employment sources in 2024-25 and one stops early in 2025-26, the ceased source's 2024-25 income still counts in your qualifying income test. This could trigger MTD even though you no longer have that income.
The Exit Problem: Can't Leave Easily
Once mandated into MTD, you can't simply opt out. The rule states you must have qualifying income below relevant threshold for three consecutive tax years to exit.
WORKED EXAMPLE 4
2026 to 2027: qualifying income £5,000
2027 to 2028: qualifying income £7,000
2028 to 2029: qualifying income £8,000
You only become eligible to opt out once you have three consecutive tax years while in MTD where your qualifying income is below the relevant threshold in each year.
2026 to 2027 | £5,000 | (below threshold) – year 1 |
2027 to 2028 | £7,000 | (below threshold) – year 2 |
2028 to 2029 | £8,000 | (below threshold) – year 3 |
You therefore first satisfy the three year condition after 2028 to 2029, so you can opt out from 2029 to 2030 onwards, if you choose.
Short or Long Periods of Account and Annualisation
Where the relevant accounting period is shorter than 12 months, HMRC guidance states that qualifying income must be annualised on a time apportioned or just and reasonable basis.
WORKED EXAMPLE 5
If you start self employment on 1 January 2025 and earn £10,000 a month, your 2024 to 2025 return might show £30,000, but this would be scaled up to £120,000 for threshold purposes, bringing you into MTD from April 2026
Tax Residency Affects Which Income Counts
UK tax residents: Both UK and foreign property income counts.
Non-UK tax residents: Only UK property income and UK self-employment income count.
If you're tax resident in Spain but own a UK rental property, only the UK property income counts toward your MTD threshold.
What This Means for You
Qualifying Income | Status | What to do |
|---|---|---|
If You're Over £50,000: ACT NOW | Mandatory from Apr 2026 | Must use MTD-compatible software. You'll file four quarterly updates plus a final year-end adjustment from 6 April 2026. |
If You're Over £30,000 But Under £50,000: PREPARE | Mandatory from Apr 2027 | Safe for April 2026. Start exploring MTD software options and structure quarterly accounting now. |
If You're Over £20,000 But Under £30,000: MONITOR | Mandatory from Apr 2028 | Safe until April 2028.Three years is not much time to prepare. |
If You're Under £20,000: SAFE | Self Assessment as usual | Continue with Self Assessment as usual for now. You can voluntarily join MTD if you want. |
Conclusion
Qualifying income is gross self-employment and property income before expenses. The £50,000 threshold is calculated from your previous year's Self Assessment return. Multiple traps exist including joint property ownership, ceased income, VAT inclusion, and tax residency differences.
Making Tax Digital isn't optional for those over the threshold. Understanding your qualifying income status today prevents scrambling at the last minute and ensures your compliance is smooth and stress-free.
