MTD with several properties: one quarterly update, not one per door

However many UK properties you own, Making Tax Digital treats them as one business and you send one quarterly update. Not one per property, not one per tenancy, not one per address.

This is the question portfolio landlords ask first and the answer is more generous than most people expect. It is also not the whole story: there are two places where the single-business rule stops, and one of them reverses the usual instinct entirely.

One UK property business

GOV.UK is direct about it: "If you have one or more properties in the UK, they are legally treated as one 'UK property business' and you do not need to create separate digital records for each UK property that you have."

So the obligation is not per property. It is:

• one set of digital records covering all your UK rental income and costs,
• totalled by your software into one quarterly update,
• four times a year, on 7 August, 7 November, 7 February and 7 May.

Your share of any jointly let UK property is part of that same business, not a separate one.

Nothing stops you keeping your records per property anyway, and most landlords should, because knowing which flat is losing money is a different and more useful question than what HMRC needs. The point is that HMRC does not require the split, so software that forces you to file separately for each address is adding work the rules never asked for.

Furnished holiday lets are inside it now

If you still think of a holiday let as a separate category, that changed before MTD arrived.

GOV.UK, listing what counts as the one UK property business: "UK properties are treated as one 'UK property business' — this includes UK furnished holiday lettings income from April 2025".

So a landlord with four long lets and a cottage on the coast has one UK property business and one quarterly update, not two of each.

Where it splits: foreign property

This is the exception, and it works in the opposite direction from what people expect.

Foreign property is a second business. If you own a flat in Spain as well as houses in Manchester, you have a UK property business and a foreign property business, and each sends its own quarterly update on the same four dates.

And then the rule inverts. For UK property you do not need separate records per property. For foreign property you do. GOV.UK: "You must create separate digital records for each individual foreign property you receive income from" and, where it is jointly let, records "relating to your share of income and expenses".

Those per-property foreign records are still added up by your software into one foreign quarterly update. The split is in the record keeping, not the filing.

If you also run a trade, that is different again: separate sole trader businesses need separate records and separate quarterly updates. GOV.UK's example is someone who is an electrician and a driving instructor, who files for each.

Buying another UK property mid-year

Nothing to register, and nothing to tell HMRC.

GOV.UK: "If you're already a UK landlord and start renting out another property in the UK, this is not treated as a new income source. This is because the property will form part of your existing property business."

What you do have to do is start keeping digital records for it "from when you start to receive rent from the property". Not from completion, not from the day the advert goes up. From the first rent.

That date matters more than it looks. The costs before the first rent, and how they are treated, belong to a different conversation than the quarterly update, but the digital record for the property starts when the money does.

Starting a genuinely new source: the two-year wait

Buying a fifth UK house is not a new income source. Buying your first foreign property, or starting a trade alongside the lettings, is.

Here the default timetable is slower than almost anyone expects. GOV.UK: you "only need to start creating digital records and sending quarterly updates for the new income source after you have included it in a tax return."

Their own worked example, and it is worth reading twice:

Start a new income source on 1 July 2026. It goes in your 2026 to 2027 tax return, which is due 31 January 2028. After that return is submitted, quarterly updates for the new source start from 6 April 2028.

So a source that begins in July 2026 can sit outside quarterly reporting until April 2028. You can opt in sooner: there is an option in your HMRC online services account to start sending quarterly updates from the date the income starts.

To add one properly you need to check your software supports the income type, add the source in your HMRC online services account (or agent services account) with its start date, and then refresh the source in your software if it does not appear.

Selling one of several

Also nothing to do.

GOV.UK: "If you stop renting out a UK property but still rent out other properties, then your property business is continuing, and you do not need to tell HMRC."

The business is the thing HMRC tracks, not the address. You carry on filing exactly as before, with one fewer property inside the totals.

If you stop letting altogether, that is a cessation and there are three steps:

1. 1Tell HMRC the date the income ended, through your HMRC online services account or agent services account. You must do this by the quarterly update deadline for the period in which it stopped.
2. 2Send the final quarterly update for the period that includes that date.
3. 3Put the ceased income in your tax return for that year, filed through MTD software.

After the tax year in which the income ceased you no longer need Making Tax Digital, but you still have to keep the digital records that support the return.

Jointly let property

Your share of a jointly let UK property sits inside your UK property business. It is not a separate business and it does not need separate treatment.

Two practical points that save arguments:

• You do not need to link your records to the other owner's. GOV.UK: "If you are a landlord that jointly lets a property, you do not need to link your digital records to the records of the other landlord." You report your share; they report theirs.
• You can report income only during the year. For jointly let property you may include income without expenses in your quarterly updates, and add the expenses afterwards by resending the fourth update before you file. If you also own property on your own, those need income and expenses in every update.

And the penalties do not multiply either

The natural next worry is that more properties means more ways to be fined. It does not.

GOV.UK: "You can only get one penalty point per deadline. This applies even if you have more than one business and send more than one quarterly update late."

So a landlord with a UK property business, a foreign property business and a trade, who files all three late on the same day, collects one point rather than three. There is no penalty at all for a late quarterly update in the 2026 to 2027 tax year, and from 2027 to 2028 it is one point per missed deadline, with a £200 penalty at four points. What a missed quarter actually costs goes through that in full.

What this means for how you keep records

The filing shape is simple: one update for UK property, one more if you own abroad, one per trade. The work is not in the filing, it is in having figures that are right on four fixed dates a year rather than one.

A few things follow for a portfolio:

1. 1Keep per property anyway. HMRC will accept the total. You need the split to know which property is worth keeping.
2. 2Tag as you go, not in the last week. Each update restates the whole tax year to date, so a receipt filed in October is still fixable in February, but only if it exists somewhere.
3. 3Do not retype records between systems. Once a digital record has been sent in an update, GOV.UK says you must not manually move it: no copy and paste, no writing it out again. Linked spreadsheet cells, CSV import and export, and API transfers are all acceptable; hand-keying is not.
4. 4Check your accounting period. Ending 5 April means standard update periods and records from 6 April. Ending 31 March means calendar update periods and records from 1 April, and you cannot change that choice once the first update has gone.

LetCompliance keeps the rent and the costs against each property as the year runs, and files the one quarterly update HMRC actually wants from the same records. It is recognised by HMRC for Making Tax Digital for UK property income, and it holds the rest of the let alongside it: the advert, the tenancy, the certificates, the notices and the deposit dates. One property is free, for as long as you want it.
