MTD qualifying income: what counts, what doesn't, and how to work out yours

Almost every “am I in MTD?” mistake comes down to one figure: qualifying income. It is not your profit, not your total income from everything, and not the figure from the year you are living in. GOV.UK defines it plainly: your total income from self-employment and property, before expenses — also known as turnover — based on the tax return you submitted in the previous tax year. Get this figure right and your start date follows; get it wrong and you may assume you are safely under a threshold when you are already over it.

The definition in one paragraph

Qualifying income is the sum of two things only: gross self-employment income and gross property income. Add every trade and every property business together into a single figure, before taking off any expenses, allowances or tax. HMRC assesses it from the Self Assessment return you submitted in the previous tax year, and GOV.UK says you should check it yourself too — even if you receive no letter from HMRC, you must still work out whether you need to use Making Tax Digital and sign up. If you are unsure which wave that puts you in, the Making Tax Digital checker works out your start date from your qualifying income.

Gross, not profit — the trap

This is the point that catches people. A sole trader with £34,000 of turnover and £21,000 of allowable expenses has a profit of £13,000 — but a qualifying income of £34,000. Expenses do not reduce the figure at all: stock, materials, fuel, insurance, agent fees and repairs are all ignored for this test. The same applies to a landlord: £55,000 of gross rents with £15,000 of costs is still £55,000 of qualifying income. If you have been comparing your profit with the £50,000, £30,000 or £20,000 thresholds, redo the comparison on turnover — the answer may change.

Note the second half of the trap: the two sources are combined. A trader on £19,000 of turnover who also lets a flat for £14,000 has qualifying income of £33,000 — over the £30,000 threshold even though neither source alone reaches it. Each source on its own may look small; added together, they may already put you in a wave.

What counts

• Self-employment income — gross turnover from every sole-trader business you run, before expenses.
• Property income — gross rents from every property business, before costs. If you were UK tax resident, foreign property income counts too: GOV.UK's example is a UK sole trader renting out a property in France, where both sources count.
• Your share of jointly owned property — only your share. Two siblings sharing £50,000 of rent equally each have qualifying income of £25,000. The one exception GOV.UK mentions: if you are only told your share after expenses have been deducted, HMRC assesses that after-expenses figure.
• Cash-basis VAT, if you include it — if you are VAT-registered and use the cash basis, you can choose to include or exclude VAT when you declare business income; if you include it, it counts towards qualifying income.
• Trust income you are entitled to — property or trading income you are entitled to as a bare-trust beneficiary counts, as does income paid directly to you as an interest-in-possession beneficiary, bypassing the trustees.
• Continuing UK-land trade income — income treated as trade profits under the transactions in UK land rules counts where it is a continuing source over more than one tax year.

What does not count

• Employment income (PAYE) — a salary alongside a side business does not push you over the threshold, however large it is.
• Your share of partnership profit as an individual partner — this does not count, and you do not keep digital records or send quarterly updates for it (though you still include it in your tax return using compatible software). Personal self-employment or property income that a partnership tells you about does count, including disguised investment management fees and income-based carried interest.
• Dividends — including dividends from your own limited company.
• Pensions — State Pension and private pensions alike.
• Transition profits from basis period reform — profits assessed in 2024/25 and the following four tax years do not count.
• Qualifying care relief — received by foster and kinship carers, it does not count.
• UK REIT and Property Authorised Investment Fund income — it does not count.
• One-off UK-land transactions — income treated as trade profits that falls within a single tax year only, and is therefore not a continuing source, does not count.
• Averaging relief — for example for farmers and creative artists, it does not affect qualifying income.

Having an excluded income source alongside self-employment or property income does not exempt you: if your qualifying income alone is over the threshold, you must still use MTD for the qualifying sources.

Which tax year decides your start date

HMRC looks backwards. Each wave tests one specific earlier return against one threshold, and the start date is roughly two years after that tax year ends:

The two waves still to come are covered in detail in MTD April 2027: what the £30,000 wave means and MTD April 2028: what the £20,000 wave means. Note the asymmetry in the April 2028 wave: unlike the £50,000 wave, it has no grace year for late quarterly updates, so its first deadlines bite immediately — see the MTD deadline calendar and MTD penalty points explained.

Four edge cases worth knowing

1. A source that has ceased still counts — sometimes

If one source has ceased since your last return but another continues, the ceased source still counts. GOV.UK's example: you were self-employed and rented out a property in 2024/25, then sold the property; because your self-employment continues, the property income still counts towards qualifying income. Only if all self-employment and property income ceased before 6 April 2026 do you fall outside MTD — and if you have not already filed a return showing that, you should contact HMRC so your records are updated.

2. Short accounting periods are annualised

If you are a sole trader and your first period was shorter than 12 months, HMRC annualises your qualifying income: six months of trading is doubled to give a full-year figure. For property income you must annualise the figure yourself.

3. Amended returns can move you in — or out

If you amend a return before the start of a tax year, the amended figure decides that year: above the threshold and you must use MTD; below it and you need not. Amend after the tax year has started and the rules split: an amendment taking you below the threshold means you do not need MTD for that year (and if you have already signed up, you may continue voluntarily or opt out), while an amendment taking you above the threshold is not considered for that tax year.

4. Non-UK residents are tested differently

If you were not UK tax resident in 2024/25, only UK property income and self-employment income declared on your UK Self Assessment return count; foreign property income and undeclared foreign self-employment income do not. GOV.UK's example: a person tax resident in Spain, renting out a UK property and trading in Spain, counts only the UK property income.

Work out your own figure in four steps

1. Take your gross self-employment turnover for the test year — total sales or fees before expenses, adding together every trade.
2. Take your gross property income for the same year — total rents before costs, using only your own share of jointly owned property.
3. Add the two together and ignore everything else: salary, pensions, dividends, savings interest and partnership profit share.
4. Compare with the threshold for that year — over £50,000 (2024/25), over £30,000 (2025/26) or over £20,000 (2026/27) — and check your start date on the Making Tax Digital checker. Landlords can follow the full annual cycle in MTD for landlords: quarterly updates, end-of-period statements and the final declaration, and if you still keep records in a spreadsheet, MTD-compatible software: spreadsheet and bridging software explains how that fits the digital-records rules.

Once you are in MTD, the test does not disappear: if your qualifying income drops below the relevant threshold for three tax years in a row, you can choose to opt out. Until then, the rhythm is four quarterly updates a year, an end-of-period statement per business, and a final declaration by 31 January — and a missed deadline starts the points clock, which you can test on the penalty estimator.
