Letting Agents and MTD: Who Actually Files the Quarterly Updates on a Managed Portfolio

You field this one every week. A landlord rings, mentions Making Tax Digital, and assumes the agency collecting the rent also files the quarterly updates.

Who files, in one line

The landlord files. Always, even on a fully managed let where the landlord has never met the tenant, and even where every penny passes through your client account.

Your agency never touches the submission. The one exception is an agency that separately holds an Agent Services Account and has been authorised for MTD ITSA filing, and almost none are.

That answers the call. What follows is the three questions that come straight back at you, and the one that costs a landlord money.

"You collect my rent, so don't you do the tax thing?" No. You run the property. The landlord, or the landlord's accountant, runs the filing.

Who does what: the agency, the landlord and the accountant

Three parties, three clean jobs. The friction lands in one place, and you are on one side of it: the handover of your statement data to whoever categorises it.

Party	Owns	Never does
Your agency	Collects the rent, pays the contractors, produces the monthly statement, controls the export format	Files the quarterly update, categorises for tax, signs off the year
The landlord	The obligation itself, the digital records, legal responsibility for what is filed	Escapes any of it by pointing at the agency
The landlord's accountant	Categorising, the quarterly submissions, the end-of-period statement and final declaration, through the Agent Services Account	Collects rent, instructs contractors, holds tenancy paperwork

That split has three consequences.

• The obligation is the landlord's. Pointing at your agency does not defer it.
• Your monthly statement is a source document, not a return. Somebody still has to categorise it.
• An accountant can absorb the categorising and the submissions. The landlord stays the responsible filer.

You hand over the statement in a readable format, plus the contractor invoices behind it. You cannot hand over authority. Only the landlord can approve an accountant to file, through the gov.uk authorisation portal with their own Government Gateway login, and the approval has to cover MTD ITSA specifically.

Which landlords are in this, and from when?

The 2026 start is only the first of three tiers, and each tier has a start date and a test year.

A landlord you act for with more than £50,000 of qualifying income files from 6 April 2026, tested against the 2024/25 tax return. At more than £30,000 the start date is 6 April 2027, tested against the 2025/26 return. At more than £20,000 it is 6 April 2028, tested against the 2026/27 return.

HMRC writes to taxpayers who look in scope. When a landlord tells you no letter arrived, treat that as a reason to check rather than a reason to relax, because the obligation stands either way.

Qualifying income is gross, and it adds up across sources. It means gross self-employment turnover plus gross property rental income, before any deductions at all. A landlord with £30,000 of trade and £25,000 of rent is at £55,000 combined, and is in.

Landlords will tell you their salary counts too. It does not. Employment income taxed under PAYE, pensions, dividends and savings interest all sit outside the test.

Joint owners test their own share of gross, never the property's total. A Form 17 election changes those shares and can pull one owner in a year ahead of the other.

Why does gross rent decide it, not the money in the landlord's bank?

"My bank statements say forty-two grand, so I'm under fifty, right?" No, and this is the single most useful correction you can make.

Reporting rent net of your fees understates the income line. It also understates the expense lines, by exactly the same amount. The two errors largely cancel for profit, which is precisely why nobody catches them.

They do not cancel for the threshold test. That test looks at gross rent the tenant paid, before commission, management fees and contractor costs. The figure that counts is the gross rent collected, never the net paid over, and that is what Making Tax Digital treats as rental income.

So a landlord collecting £52,000 of gross rent, with £42,000 reaching the bank, is in from 6 April 2026 whatever the bank statements suggest. The gross figure at the top of your statement is the number that decides whether that landlord is in scope at all. That is why landlords ring their agent about it and not their bank.

How does a monthly statement map into the quarterly update?

Take one fully managed three-bed, for a landlord you act for, in one month:

• Gross rent collected: £1,650
• Agency commission: £165
• Monthly management admin: £20
• Gutter clean, contractor invoice: £90
• Boiler service, contractor invoice: £135
• Annual gas safety inspection fee: £60
• Net paid to the landlord's bank: £1,180

Those seven lines land in four places. Gross rent of £1,650 is the property income line. Commission and management admin, £185 together, go to legal, management and other professional fees. The gutter clean and the boiler service, £225 together, go to property repairs and maintenance. The gas safety fee of £60 goes to other allowable property expenses.

Now the payload. The £1,180 that reached the landlord's bank appears nowhere on the quarterly update. It is a sanity check, nothing more.

The dates are fixed, and worth knowing by heart. Rent collected between 6 April and 5 July is filed by 7 August. The next three quarters are filed by 7 November, by 7 February and by 7 May. The end-of-period statement and the final declaration both follow by 31 January after the tax year ends.

You will meet two edge cases. A void month shows a zero income line with the expense lines still running, and that is exactly what you put on the update. A year-end reconciliation landing in May does not reopen a closed quarter, because adjustments of that kind flow through the end-of-period statement and the final declaration.

Three properties, three agencies: how many filings?

One. The landlord files a single cycle covering all their UK property income, however many properties and agencies feed into it. There is no per-property or per-agency return.

Gross rent from every statement adds into one income line, and each expense category adds the same way. Three agencies means three formats and three sets of conventions, not three submissions. If you are one of the three, a clean export is the most useful thing you can hand over.

Joint ownership works the same way one layer down. Each owner records their share of every line on your statement, on the beneficial-ownership split, with 50/50 the default for married couples absent a Form 17 election. One statement, two parallel filings. Running two cycles side by side has its own mechanics, set out on our joint-owner quarterly filing page.

Is a PDF statement enough, or does the landlord need a CSV?

You control this part, and the export format you choose decides whether the landlord's records hold up.

A digital link is a transfer of data between software or spreadsheet cells with no manual transcription and no copy-paste. Cell references and formulae count, and so do linked tables, an API extract and a CSV import run by a script.

Copy-paste does not count, nor does re-keying by hand, nor reading a number off a screen and typing it in.

The consequence is simple. A PDF statement is not itself a digital record, and a landlord who retypes your PDF figures into a spreadsheet has already broken the chain. Offer a CSV or a structured export alongside the PDF and that problem disappears for every landlord on your books, at no cost to you.

Spreadsheet columns should follow the categories the tax return uses: gross rent, agent fees, repairs, insurance, council tax, finance costs and other. Categorised that way, the figures flow through bridging software into the quarterly update with nobody retyping anything. HMRC keeps its own list of compatible software, and it changes, so point landlords at the list rather than a product.

"Can you just email me the numbers in January?" You can, but it will not help. The landlord needs those figures every quarter, in a format their software can actually read.

What has not changed

None of this moved, and a landlord who believes otherwise has read something wrong.

• Your agency still collects the rent, still pays the contractors and still produces the statement.
• Your agency is still not the landlord's tax agent, and managing the property has never made it one.
• An old 64-8 signed for Self Assessment still does not authorise quarterly filing under the new regime.
• The landlord still files one cycle for the whole portfolio, however many agencies are involved.
• Deposit protection, Right to Rent and tenancy paperwork are untouched by any of this.
• Non-Resident Landlord Scheme withholding still runs alongside the filing rather than instead of it, and the tax withheld is a credit at the final declaration.
• The 31 January final declaration date has not moved.

What happens if a landlord misses a quarterly update?

You will get asked this one. Late submission is points-based, not an instant fine. One missed quarterly update earns one point. For quarterly filers the penalty threshold is four points. The fourth missed update takes a landlord to that threshold and triggers a £200 penalty, and every missed submission after that costs another £200.

Points do not clear easily. A reset needs both a 12-month period of compliance and every submission due in the preceding 24 months actually made.

Late payment is a separate regime and it bites faster. For the 2026 to 2027 tax year it runs at 3% of the unpaid tax from day 15, a further 3% from day 30, then 10% a year from day 31.

One softener lands on exactly the landlords starting in April 2026. In a landlord's first year of the new penalties, HMRC allows 30 days from the payment due date to pay in full or agree a payment plan before any late-payment penalty starts. That concession is once only.

What can you safely tell a landlord, and where is the line?

You can say all of this without going anywhere near tax advice:

• The landlord is the filer, and the agency is not.
• What each line on your statement is, and which line is the gross rent.
• That gross rent, not the net figure paid over, is what the threshold test looks at.
• That your agency can supply a CSV or a structured export.
• The quarterly dates, and the 31 January date at the end of the cycle.

Send these to the landlord's accountant instead:

• Whether this landlord is over the threshold, because it turns on income you never see.
• How a joint-ownership split should be recorded, and anything touching a Form 17 election.
• Whether to elect calendar quarters.
• Any question that starts with "should I".

A clean handoff sounds like this. "I can tell you what your statement says and what every line on it is. Whether you are over the threshold depends on income I never see, so that goes to your accountant."

What to change about your statement run

You already produce a monthly statement and an annual export. Neither needs replacing.

Change the format they come out in. Put a CSV or a structured export next to the PDF, keep the columns in the tax categories, and keep gross rent on its own line, not netted down. Do that once and every landlord you act for can hand an accountant something that flows straight through.

Where do the deeper questions go?

Letting agent MTD questions run into four neighbouring areas, each with its own page. For the big picture, start with our MTD ITSA overview for residential landlords. To settle whether a landlord is in scope, our qualifying-income test page works the gross-only rule through with figures. For two owners and one statement, the joint-owner quarterly filing mechanics page runs two cycles side by side. To get an accountant authorised, our Agent Services Account walkthrough takes the handshake step by step. And where you withhold tax for an overseas landlord, our NRL scheme letting agents page covers the withholding side. The rest of this year's landlord questions are collected on our letting agent hub.

The operative instrument is the Income Tax (Digital Obligations) Regulations 2026, which replaced the 2021 digital requirements regulations on 1 April 2026.
