The 7 August MTD Deadline: A Last-Minute Guide for Landlords

On 7 August 2026, the first quarterly update under Making Tax Digital for Income Tax (MTD ITSA) falls due. It is the first genuinely new tax filing deadline UK landlords have faced in years, there is no precedent to copy, and the tone of most of the coverage over the past fortnight has been closer to alarm than to instruction.

Two things are probably true if you are reading this ten days out. The first is that there is a meaningful chance you are not actually in scope, because the threshold is measured in a way that catches fewer landlords than the headlines suggest. The second is that if you are in scope, 2026/27 is by some distance the most forgiving year this regime will ever have — HMRC is not issuing penalty points for late quarterly updates during the first year, and quarterly updates are cumulative, so an imperfect first submission can be corrected in the next one without a correction process, an amendment form or a phone call.

This article is a triage, not a lecture. It works in the order you should work: confirm scope first, understand what is genuinely at stake second, then follow a day-by-day plan for the ten days remaining. It applies to individuals with UK property income who are within MTD ITSA. Landlords who hold property through a limited company are outside MTD ITSA entirely and have no 7 August obligation.

Do I Actually Have to File by 7 August?

Only if your qualifying income exceeded £50,000. Making Tax Digital for Income Tax became mandatory on 6 April 2026 for individuals whose qualifying income from UK property and self-employment was above £50,000, as assessed by HMRC from the 2024/25 Self Assessment return. If you were below that, you have nothing to file on 7 August 2026 and you continue with Self Assessment exactly as before.

A large share of the landlords currently worrying about this deadline are not in scope, and two details of the threshold are responsible for most of the confusion.

The first is that qualifying income is gross, not profit. It is rent received and trade turnover before mortgage interest, before letting agent fees, before repairs and before every other expense. A portfolio turning over £62,000 and netting £11,000 of profit is in scope; a portfolio turning over £44,000 and netting £30,000 is not. This catches out landlords who think in terms of what they actually keep — but it also means the test is easy to run, because gross rent is the one number every landlord knows.

The second is that jointly owned property counts on your share. If you and a spouse or partner own property generating £76,000 of rent between you on a 50/50 basis, you each have £38,000 of qualifying property income and neither of you is in scope on that alone. HMRC assesses each individual separately, and the threshold is not a household test. Our guide to MTD quarterly submissions covers how joint shares flow through into the figures you eventually report.

A Two-Minute Scope Check

1. Take your gross UK property income for 2024/25 — total rent received, before any expenses at all.
2. Reduce jointly owned property to your beneficial share only. A 50% owner counts £19,000 of a £38,000 rent, not £38,000.
3. Add gross self-employment or sole-trader turnover for the same year, if you have any. The two are combined for the threshold test.
4. Compare the total to £50,000. Above it, you are in MTD ITSA for 2026/27 and 7 August applies to you. At or below it, you are not — file Self Assessment as usual.
5. Ignore anything held in a limited company. Companies pay Corporation Tax and sit outside MTD ITSA. Rent from a company-held property is not part of your personal qualifying income.

What Happens If I Miss the 7 August Deadline?

Less than you probably fear, in this specific year. HMRC has confirmed that no penalty points will be issued for late quarterly updates during 2026/27. The points-based late submission regime for MTD ITSA quarterly updates begins in April 2027. From that point, a quarterly filer who accumulates four points triggers a £200 penalty — but that structure does not bite on anything you file, or fail to file, for the 2026/27 tax year.

That easement exists because HMRC understands the first year of a new regime produces a large volume of honest mistakes, and it would rather have people filing imperfectly than not filing at all. It is a deliberate soft landing, and you are allowed to use it.

Three things it does not do, which matter just as much:

• It does not remove the obligation. If you are in scope, you are legally required to submit quarterly updates. "No penalty points this year" is not the same as "optional this year", and building a habit of missing deadlines going into a year when they carry points is a poor trade.
• It does not cover late payment. Late payment penalties and interest on tax owed are an entirely separate regime and are unaffected by the quarterly-update easement. Quarterly updates do not themselves create a tax payment, but your normal Self Assessment payment obligations continue unchanged.
• It does not extend to the final declaration. Your final declaration for 2026/27 is due 31 January 2028, and that is the submission which actually determines your tax. It carries the same seriousness as a Self Assessment return always has.

Our guide to MTD penalties for landlords sets out the full points structure and how it will work once it starts in April 2027.

What If My Figures Are Not Perfect Yet?

File anyway, because quarterly updates are cumulative and self-correcting. This is the single most anxiety-reducing feature of MTD ITSA and it is barely mentioned in most coverage of the deadline.

Each quarterly update restates your position for the tax year to date, rather than reporting that quarter in isolation. Your Q2 update, due 7 November 2026, covers 6 April to 5 October — the whole period, including the months already covered by Q1. If a receipt surfaces in September for an August repair you had forgotten, or you realise in October that you categorised a service charge wrongly in May, you simply include the corrected figures in the next update. The year-to-date total supersedes what came before. There is no amendment process to learn, no correction form, and no need to contact HMRC.

This changes what a good first filing looks like. The goal for 7 August is an honest, reasonable, complete-as-you-can-make-it set of totals — not an audited set of accounts. A landlord who files on time with figures that are 95% right and tidies up in November is in a far better position than one who spends the next ten days hunting a missing receipt and files nothing.

Your Day-by-Day Plan for the Next Ten Days

If you are in scope and starting from nothing, ten days is enough. The plan below deliberately front-loads the two steps that can fail in ways you cannot fix by working harder: choosing a filing route, and getting the software authorised to talk to HMRC. Assembling records is tedious but predictable; authorisation is quick when it works and can cost you two days when it does not.

What Are My Options If I Have No MTD Software Yet?

You have three legitimate routes, and all three can realistically be arranged inside ten days. The obligation on you is to keep digital records and to file through software that is compatible with HMRC's MTD ITSA system. There is no requirement that the software keeping your records is the same software that files them.

For the mechanics of the spreadsheet route, see our explainer on MTD bridging software and Excel. For how to read the finder and what "HMRC recognised" does and does not certify, our guide to HMRC-recognised MTD software for landlords is the honest version — including the fact that Latch is not on HMRC's software finder, so landlords using Latch file through bridging software or through their accountant.

One route that does not exist: there is no HMRC web form for typing quarterly update totals in by hand. Compatible software is the only channel, which is why choosing a route is genuinely the first task and not an optional preliminary.

What Actually Goes Into a Quarterly Update?

Totals by category for the period — and nothing else. A quarterly update is not a tax return, not a tax calculation, and not a payment. It is a summary of income and expenses for your UK property business over the quarter, broken down into HMRC's categories. Understanding how small the submission actually is takes a great deal of the fear out of it.

For a UK property business, the categories are the ones you already recognise from the property pages of a Self Assessment return:

• Rent and other income from property, including any premiums and service charges received
• Rent, rates, insurance and ground rents
• Property repairs and maintenance
• Loan interest and other financial costs
• Legal, management and other professional fees
• Costs of services provided, including wages
• Other allowable property expenses

Several things you might expect to be part of it are not. There is no tax calculation in a quarterly update, and no tax becomes payable because you filed one. Accounting and tax adjustments — capital allowances, the finance-cost restriction that turns residential mortgage interest into a basic-rate tax reducer, private-use adjustments, property allowance claims — are not made quarterly. They belong to the final declaration on 31 January 2028, which is where your actual tax liability for 2026/27 is settled.

HMRC also treats all your UK residential properties as a single UK property business for reporting purposes, so you submit one set of combined totals rather than a separate update per property. You should still keep per-property figures in your records — you will want them for decisions, apportionments and questions later — but the submission itself is aggregated. If you want to see the process screen by screen before you attempt it, our first MTD quarterly submission walkthrough covers it end to end.

What Do First-Time Filers Get Wrong?

The errors below are the ones that cause real problems, in the sense that they either block the submission or produce figures that need unpicking later. Work through them before you file rather than after.

• Filing on profit instead of gross figures. Report gross rent received as income and expenses separately. Netting expenses off rent before you enter it understates both sides and produces the wrong year-end position.
• Reporting the full rent on a jointly owned property. Enter your beneficial share only. This is the most common single error among couples, and it doubles the reported income of the property.
• Using the wrong quarter dates. The standard first quarter is 6 April to 5 July 2026. If you have elected for calendar quarters it is 1 April to 30 June 2026. The deadline is 7 August 2026 either way — the election changes the period, not the filing date.
• Leaving the calendar-quarter election until after you file. If you want month-end periods, set the election in your software before submitting. Switching afterwards means periods that no longer line up with what you have already sent.
• Mixing tax years at the boundary. Rent received on 3 April 2026 belongs to 2025/26 and your old Self Assessment return, not to this quarter. Check both ends of the period for transactions that have drifted across.
• Treating an improvement as a repair. Replacing a broken boiler with an equivalent one is a repair; adding an extension is capital. Getting this wrong quarterly is correctable, but it is easier to categorise it right the first time.
• Including limited company property. Rent from property held in a company is outside MTD ITSA and must not appear in your personal quarterly update.
• Retyping totals rather than linking them. Once data is digital it must move between programs by a digital link — an export and import, linked cells, or an API — not by reading a number off one screen and typing it into another.
• Not saving the submission receipt. Keep the confirmation and reference number your software returns. It is your evidence that you filed, and the easiest thing in the world to lose.
• Assuming a filed update means tax is paid. It does not. Quarterly updates are informational; your payment obligations run on the Self Assessment timetable and are unchanged.

What Happens After 7 August?

Three more quarterly updates and then a final declaration. Once the first filing is behind you, the rhythm of MTD ITSA is predictable, and every subsequent quarter is easier than the first because the software is already authorised and the categories are already set up.

The two middle columns are the distinction worth reading twice: each update is triggered by a discrete quarter, but the figures you submit restate the whole tax year to date. Each update covers the year to date, which is exactly why an honest Q1 that turns out to be slightly wrong is a genuinely small problem — you are restating the whole period in November regardless. The final declaration on 31 January 2028 replaces the Self Assessment return you would previously have filed, and it is where reliefs, allowances and adjustments are applied.
