MTD with multiple income sources: how many updates do you need to file?
If you have more than one source of qualifying income, your number of quarterly updates goes up. Here is exactly how the maths works.
The basic rule
Most MTD content assumes you have a single income source. In practice, a lot of people have two or more: a sole trade and a rental property, two separate businesses, or rental income from both UK and overseas properties.
The rule is straightforward. Each sole trade needs its own set of four quarterly updates. All UK property income is treated as one property business with one set of four updates. Overseas property income is a separate business with its own four updates. The number of updates you file each year depends on how many of these MTD business sources you have.
There is still only one MTD tax return at the end of the year, regardless of how many MTD business sources you have. That covers everything in one go.
| Your situation | Quarterly updates per year | MTD tax returns per year |
|---|---|---|
| One sole trade | 4 | 1 |
| One UK property business | 4 | 1 |
| One sole trade + one UK property business | 8 | 1 |
| Two sole trades | 8 | 1 |
| Two sole trades + one UK property business | 12 | 1 |
| UK property business + overseas property business | 8 | 1 |
Self-employed and a landlord
This is the most common combination. If you run your own business and also receive rental income, HMRC treats each as a separate business for MTD. That means eight quarterly updates per year: four for your trade and four for your property income.
Take Sara. She runs a photography business and rents out a flat. Neither income source alone clears £50,000, but combined they do. So she files four quarterly updates covering her photography income, four covering her rental income, and one MTD tax return at the end of the year covering both, plus anything else such as employment income or savings interest.
All UK rental properties count as one business. Whether you have one rental or ten, it is still one set of four quarterly updates. The number of properties does not change the number of updates. See our landlord page for more on how multiple properties work.
Running two separate businesses
Each sole trade is its own business for MTD. If you run two genuinely separate trades, you need two separate sets of digital records and two separate sets of quarterly updates.
Take Marcus. He works as a freelance graphic designer and also runs a separate mobile car valeting business. They operate under different names, have different clients, and are different activities. HMRC treats them as two trades. Marcus files eight quarterly updates per year: four for the design work and four for the valeting.
If Marcus also had a rental property, that would add another four updates, making twelve in total.
Not sure whether your activities count as one trade or two? Indicators may include different business names, different customers, separate records, and activities with little connection to each other. Whether activities are one trade or two can be fact-sensitive. If you are unsure, check before signing up for MTD, since the number of sources determines how many updates you will be expected to file.
UK and overseas rental income
This is one situation where a landlord files more than one set of quarterly updates, even with no sole trade income at all.
UK property income and overseas property income are treated as two separate businesses under MTD. If you receive rent from a property in the UK and from one abroad, you need two sets of digital records and eight quarterly updates per year: four for your UK portfolio and four for your overseas portfolio.
The record-keeping rules also differ. For UK properties, you combine all your properties into one set of records. For overseas properties, you keep records for each individual property separately.
If you are UK resident, overseas property income counts towards your qualifying income threshold. If your UK rental income is below £50,000 but your combined UK and overseas rental income takes you over it, you are in scope for MTD. Different rules apply for non-UK residents. The threshold is based on all qualifying income combined, not on any single source alone.
Starting a new business or property while you are in MTD
If you start a new sole trade, or your first foreign property, while you are in MTD, you do not have to start quarterly updates for it straight away. You add it to your HMRC online account and include it in your next tax return. Quarterly updates for it start after that return. HMRC's example: a new business started on 1 July 2026 goes on the 2026/27 tax return, and quarterly updates for it start from 6 April 2028. You can choose to start sooner.
A new UK rental property is different. It joins your existing UK property business, so you keep records for it from the first rent.
Jointly owned property
If you own rental properties jointly with someone else, each owner files their own quarterly updates independently. There is no joint filing.
You report only your own share of the income. Under HMRC's joint-property easement, you can report income only in quarterly updates and leave expenses until after the end of the tax year. Before you submit your MTD tax return, you must add the expenses by resending your fourth quarterly update.
Regardless of how many co-owners a property has, or whether different properties have different co-owners, all of your jointly owned UK properties still form part of your single UK property business. The number of co-ownership arrangements does not increase your number of quarterly updates.

If you miss a deadline
After your first year in MTD (2026/27 if you joined in April 2026, 2027/28 if you join in April 2027*), you receive one penalty point per quarterly deadline missed, regardless of how many MTD business sources are late on the same date. Missing the August deadline for both your trade and your property income costs one point, not two.
Keeping the records separate
Each income source needs its own digital records. You cannot combine trade income and rental income into one set of figures.
In practice, some MTD-compatible software supports multiple income sources within a single account, so you do not necessarily need separate logins or tools. The key requirement is that the records, and the quarterly updates generated from them, are kept distinct per source.
See our software page for guidance on which products handle multiple income sources and how they differ.
Common questions
Eight quarterly updates per year: four for your self-employment income and four for your property income. They cover the same periods and have the same deadlines, but they are submitted separately. You then file one MTD tax return at the end of the year covering both.
One set. All UK rental properties are treated as a single property business for MTD purposes. Five properties, one set of four quarterly updates. The number of properties has no effect on the number of updates you file.
Eight. UK property income and overseas property income are treated as two separate businesses under MTD. Your two UK properties together form one business with four quarterly updates, and your Spanish property forms a second business with another four. One MTD tax return covers everything at year end.
Not necessarily. Some MTD-compatible software supports multiple income sources within one account. Others require separate accounts per source. The requirement is that the records and submissions are kept separate, not that you use separate tools. Check before committing to a product if you have more than one source.
No. After your first year in MTD (2026/27 if you joined in April 2026, 2027/28 if you join in April 2027*), you receive one penalty point per quarterly deadline, regardless of how many MTD business sources you miss on that date. Missing two sources on the same deadline costs one point, not two.
No. Each owner's MTD obligations are entirely independent. What your wife files, and when, has no bearing on your own submissions. You each report your own share of the income and file your own updates on your own schedule.
