How Qualifying Income Is Calculated for MTD
Qualifying income is your gross self-employment and property income, added together. Here's what counts, what doesn't, and the edge cases that catch people out.
What counts as qualifying income
Qualifying income is the total you get in a tax year from self-employment and property, added together if you have both. It's measured on a gross basis, your turnover before expenses, not your profit.
If you've already read our page on who needs to use MTD, you've seen the basic mechanics: gross income, combined across sources, tested against the threshold for your tax year. This page goes further into how that figure is actually built, including a few cases that don't come up often but cause real confusion when they do.
Each sole trade is treated separately for MTD. UK property income is treated as one UK property business, however many UK properties you have. Overseas property income is treated as a separate business from your UK property. So if you have three UK rentals and one abroad, that is two property income figures, not one. See our page on multiple income sources for how the filing side of this works.
What's excluded
A number of income types are reported through Self Assessment but never count towards your qualifying income, however much you receive:
- Employment income (PAYE)
- Your share of profit from a partnership, as an individual partner
- Dividends, including from your own company
- Savings interest
- Capital gains made from selling assets
- State Pension and private pensions
This is why a director who also has a rental property only needs to look at the rental figure, not the dividends. And it's why someone with a sizeable pension and a small side trade is judged purely on the trade.
One situation is more complex. Where HMRC treats land transactions as trading profits under the transactions in UK land rules, the income can count towards qualifying income if it is a continuing source across more than one tax year. A one-off transaction does not count. This is distinct from normal capital gains on asset sales, which remain excluded.
The partnership exception
Partnership profit share is excluded, but there's a nuance worth knowing if you're a partner. Two specific types of personal income are treated differently and do count towards your qualifying income:
- Disguised investment management fees, payments structured to look like a return on investment rather than a fee for managing it
- Income-based carried interest, the portion of a fund manager's carried interest that HMRC taxes as income rather than as a capital gain, because the fund's investments were held for a relatively short average period
HMRC treats both as profits of a trade, so they're taxed, and counted for MTD, as your own trading income rather than as partnership profit share. These amounts create a separate personal MTD obligation - digital records and quarterly updates for those specific income streams. Your ordinary share of partnership profit stays outside the qualifying income calculation entirely. You do not need digital records or quarterly updates for that.
For most partners this won't apply. It's only relevant if your partnership arrangement involves these specific payment types, which tend to come up in private equity, venture capital and similar fund structures.
Some income types have specific rules not covered here. These include foreign property income, trust income (bare trusts and interest in possession trusts), qualifying care relief, and basis period transition profits. People eligible for qualifying care relief are exempt from MTD until further notice.* See our page on MTD exemptions. If any of these apply to your situation, take advice on whether and how they count towards your threshold before assuming you are inside or outside scope.
Worked example: combining two sources
Say you're a sole trader with a rental property on the side:
| Income source | Gross amount |
|---|---|
| Self-employment | £27,000 |
| Property income | £25,000 |
| Combined qualifying income | £52,000 |
Neither figure alone clears £50,000, but added together they do, so this person is in scope from April 2026. The same logic applies however many sources you have. Add up every qualifying source first, then test the total against the threshold for the relevant tax year.
Jointly owned property
If you own a property with someone else, only your own share counts towards your qualifying income, not the total rent the property generates.
A £50,000 property split 50:50 means £25,000 each, not £50,000 each. If you only find out your share after expenses have already been deducted, HMRC will work with that net figure rather than asking you to reconstruct the gross amount. See our page on MTD for landlords for the full detail on joint ownership, including how this interacts with the threshold.
Income sources that have ceased still count
This one surprises people. If a self-employment or property income source stopped during the tax year, the income it generated before it stopped still counts towards your qualifying income, as long as you have at least one other self-employment or property source that's still going.
Example: you had three separate sole trades on last year's tax return. One of them closed down partway through the year, but the other two are still running. The income from the closed trade still counts towards your qualifying income for that year, on top of the two that continue.
The position is different if every qualifying source has stopped. If they all stopped before your MTD start date, you will not need to use MTD, but you need to tell HMRC. If you do not, HMRC may sign you up based on the information it holds. You still file a tax return for the year the income stopped.
If they all stop after your MTD start date, you send a final quarterly update covering the period up to the date they stopped. You then file that year's tax return through your MTD software. After that, you no longer need to use MTD.
Allowances do not reduce your qualifying income
When HMRC assesses your qualifying income, it uses your gross income before expenses and before any relief or allowance is applied.
The trading allowance (up to £1,000 for small amounts of trading or casual income, rising to £3,000 from 2027/28*), the property income allowance (up to £1,000 for property income) and Rent-a-Room relief (up to £7,500 for letting a furnished room in your own home) reduce or remove your tax liability on small amounts of income. They do not reduce the gross income figure HMRC uses to assess your qualifying income.
If your gross income from one of these sources is approaching the threshold when combined with your other income, take advice on how your specific figures interact. HMRC's qualifying income guidance does not address these allowances and reliefs in detail.
Short or part-year accounting periods
If you've only been trading or letting for part of a tax year, your qualifying income is normally scaled up to a 12-month equivalent rather than judged on the raw figure. In most cases this means straight-line proportioning, though a just and reasonable basis can apply where that would produce an unfair result.
HMRC annualises this automatically where it has the information. If you started trading and only had 6 months of activity in your first tax year, your income for that period is doubled to estimate the full-year figure.
This isn't done for you. If your property income only covers part of a tax year, for example because you bought the property partway through, you need to annualise the figure yourself before comparing it to the threshold.
Common questions
Only your own share. If you and a co-owner split the rent equally, you each count half of the gross income towards your individual qualifying income, not the full amount each.
It still counts, provided you have at least one other self-employment or property source still running. If every qualifying source stopped before your MTD start date, you won't need to use MTD, but tell HMRC or it may sign you up anyway. If they stop after you have started, you finish that year in MTD and then leave.
No, your share of partnership profit as an individual partner is excluded. The exception is disguised investment management fees and income-based carried interest, both treated as your own trading income rather than profit share, which do count.
Turnover. Qualifying income is your gross income before expenses, sometimes called your turnover, not your profit after costs. A business with high turnover and low margins can be well over the threshold despite making relatively little profit.
Your income needs to be scaled up to a full year. For sole traders, HMRC does this automatically where it has the information. Landlords need to annualise their own property income for any part year before checking it against the threshold.
*Announced in the Budget on 28 October 2026. A Budget announcement becomes law in one of two ways. Most tax changes go into the annual Finance Bill, which becomes law when it receives Royal Assent, usually early the following year. Others are made by regulations laid before Parliament. Until then, the details can change.
