MTD Quarterly Update Deadline 7 August 2026: Sole Trader and Landlord Guide

The first MTD quarterly update for many sole traders and landlords is due by 7 August 2026. That sounds comfortably far away in late April, but the update covers income and expenses from the start of the new Making Tax Digital year. If your records for April, May and June are already drifting into bank-statement archaeology, the August filing will be more awkward than it needs to be.

For people in phase one of Making Tax Digital for Income Tax, the real change is not a new tax rate. It is the rhythm. HMRC now expects digital records during the year, quarterly summaries through compatible software, and a final tax return later. The first update is where that new rhythm becomes real.

Quick summary: if you joined Making Tax Digital for Income Tax from 6 April 2026, your first quarterly update is usually due by 7 August 2026. Standard update periods run from 6 April to 5 July. Calendar update periods run from 1 April to 30 June. The update sends category totals, not every receipt, and HMRC says there are no late quarterly update penalties for 2026/27, but you still need to send the updates before you can finalise the tax year.

If you want us to check whether your bookkeeping is ready before the first filing, we can help through our Self Assessment service, bookkeeping support, and contact page.

MTD quarterly update deadline: the dates that matter

The first thing to pin down is the filing calendar. HMRC’s current Making Tax Digital for Income Tax guidance sets out two possible quarterly patterns.

Update pattern	First period covered	First deadline
Standard update periods	6 April to 5 July 2026	7 August 2026
Calendar update periods	1 April to 30 June 2026	7 August 2026

The later deadlines for the first Making Tax Digital year are:

Update	Standard period	Calendar period	Deadline
Q1	6 April to 5 July 2026	1 April to 30 June 2026	7 August 2026
Q2	6 April to 5 October 2026	1 April to 30 September 2026	7 November 2026
Q3	6 April to 5 January 2027	1 April to 31 December 2026	7 February 2027
Q4	6 April to 5 April 2027	1 April to 31 March 2027	7 May 2027
Final tax return for 2026/27	Whole tax year	Whole tax year	31 January 2028

One practical detail matters here. Standard update periods are cumulative in HMRC’s table, so the second update covers records from 6 April to 5 October, including earlier records and later corrections. In day-to-day terms, you should still run a proper close at the end of each quarter. Treating every update as one giant open file is how errors hang around until January.

Who needs to send the first update in 2026?

Making Tax Digital for Income Tax is being phased in. For 2026/27, it applies to people already registered for Self Assessment who have qualifying income over £50,000 from self-employment, property, or both, based on the 2024/25 tax return.

HMRC’s staged thresholds are:

Start date	Qualifying income test
6 April 2026	More than £50,000 on the 2024/25 tax return
6 April 2027	More than £30,000 on the 2025/26 tax return
6 April 2028	More than £20,000 on the 2026/27 tax return

Qualifying income means turnover from self-employment and property income before expenses. It is not the same as profit.

Worked example 1: income threshold for a sole trader

Assume a freelance consultant submitted a 2024/25 Self Assessment return showing:

• turnover from consulting: £58,000
• allowable business expenses: £14,000
• taxable profit before personal allowance: £44,000

The Making Tax Digital entry test looks at the £58,000 turnover figure, not the £44,000 profit. Because qualifying income is over £50,000, the consultant is in phase one from 6 April 2026 and needs to prepare the first quarterly update by 7 August 2026.

That does not mean their tax has increased. It means the record keeping and filing process has changed.

Worked example 2: combined self-employment and property income

Now take a part-time designer who also rents out a flat. Their 2024/25 return showed:

• self-employment turnover: £33,000
• gross rental income: £21,600
• total qualifying income: £54,600

Neither source is over £50,000 by itself. Together, they are. That person should expect to follow Making Tax Digital for Income Tax from 6 April 2026, unless a specific exemption applies.

Your specific position can differ if income sources started or stopped, if HMRC has not yet processed the relevant return, or if an exemption applies. If you are close to a threshold, do not guess. Check the return used for the entry test and keep a note of the figures.

What actually goes into an MTD quarterly update?

An MTD quarterly update is a summary of digital records. HMRC says it receives totals for each relevant income and expense category, not details of every individual receipt or transaction.

For a typical sole trader, the categories include:

Area	Examples of what may be included
Business income	Turnover and other business income
Cost of goods	Stock bought for resale or goods used
Staff costs	Wages, salaries and other staff costs
Travel	Car, van and travel expenses
Premises	Rent, rates, power and insurance
Repairs	Repairs and maintenance of property and equipment
Office costs	Phone, stationery and other office costs
Professional fees	Accountancy, legal and other professional fees
Finance costs	Bank charges, credit card charges and loan interest
Other costs	Other business expenses

For landlords, the update works around property income and property expense categories. HMRC’s direction includes categories such as total rent, other property income, repairs and maintenance, finance costs, legal and management fees, travel expenses, and other allowable property expenses.

Jointly let properties have a useful wrinkle. HMRC says a landlord with jointly let property can choose to include all property income and expenses for those properties, or only property income without expenses. If expenses are left out during the year, they still need to be reported before the annual tax position is finalised.

That point matters for couples, family-owned rental properties, and shared investments. The simplest quarterly option is not always the best year-end option, so agree the approach before the first update is sent.

What the first update does not do

A lot of anxiety around Making Tax Digital comes from assuming the quarterly update is a mini tax return. It is not.

The first update does not normally:

• calculate your final tax bill for the year
• trigger a new quarterly tax payment
• include every adjustment you would make at year-end
• replace the need for the 2026/27 final tax return
• send HMRC every line of your bank feed

You still need to complete the year-end tax return process through software by 31 January 2028 for the 2026/27 year. That is where you check the full position, add other income where needed, claim reliefs and allowances, and finalise the tax due.

Payments on account also remain part of Self Assessment unless the rules change for your circumstances. Many taxpayers will still pay tax on 31 January and 31 July. The quarterly update is about reporting, not four automatic tax bills.

Worked example 3: why a quarterly update is not the final tax answer

Assume a self-employed photographer records the following from 6 April to 5 July 2026:

• client income: £18,000
• camera hire and equipment rental: £1,200
• travel: £650
• software subscriptions: £390
• accountancy and legal fees: £300
• other business costs: £460

The Q1 update sends category totals based on those records. It does not decide all annual claims.

Later in the year, the photographer buys a camera body for £3,000. Capital allowance treatment is checked at the final tax return stage. They also make a pension contribution of £4,000 and have savings interest from a personal account. Those points do not all sit neatly inside the first quarterly update.

The quarterly update gives HMRC and the taxpayer a current view. The final tax position still needs a proper year-end review.

How to prepare before 7 August

The best preparation is not heroic. It is routine bookkeeping done before the quarter goes cold.

Use May and June to get the process into shape:

• confirm which update pattern your software is using
• connect the right business bank accounts
• separate personal spending from business spending
• check that income is being posted to the right source
• agree categories for regular costs
• attach digital evidence for larger or unusual items
• reconcile bank transactions at least monthly
• test whether your accountant can access the software
• make sure your Government Gateway and software permissions work

If your records are currently spreadsheet-based, the key question is whether your setup uses compatible software or compliant bridging software. A spreadsheet saved on your desktop is not automatically enough. HMRC says software can be all-in-one or a linked set of products, but the records and submission route need to meet the Making Tax Digital rules.

For businesses already filing VAT through software, the habit will feel familiar. The main difference is the income tax categories, the personal tax return link, and the need to separate self-employment and property sources where relevant. Our VAT returns service and bookkeeping service can help if your VAT records and income tax records need to be made consistent.

What if April records are already messy?

Fix them now. Waiting until the first week of August turns a small clean-up into deadline pressure.

Start with the bank account. Reconcile April fully, then May, then June. Do not begin by trying to make the quarterly report look right. A tidy report is usually the result of clean transaction coding, not the starting point.

A practical clean-up order:

• bank feed connected and up to date
• sales matched to invoices or income records
• duplicate transfers removed
• private spending coded outside business costs
• missing receipts requested or recreated where possible
• regular subscriptions checked for VAT and business use
• mixed-use costs marked for later adjustment
• one-off items explained with a short note

Worked example 4: how small coding errors distort the first update

Suppose a sole trader has £24,000 of Q1 income and £7,800 of costs in the software. During a review, they find:

• £1,200 of personal holiday spending coded as travel
• £850 of business software invoices sitting unposted
• £400 of bank charges coded as drawings
• £300 of client reimbursement income posted as a loan

The original report showed expenses of £7,800. After corrections:

• remove personal travel: £7,800 - £1,200 = £6,600
• add software invoices: £6,600 + £850 = £7,450
• add bank charges: £7,450 + £400 = £7,850
• correct reimbursement income from loan to business income: income rises from £24,000 to £24,300

The update now gives a better picture of the quarter. More importantly, the January 2028 year-end work will not start with a pile of small, forgotten errors.

Year-one penalty relief is useful, but it is not permission to ignore the update

HMRC says there are no penalties for missing a quarterly update deadline for the 2026/27 tax year. That is helpful, especially while software, agents and taxpayers adapt to the new process.

Do not read too much comfort into it.

You still need to keep digital records. You still need to send quarterly updates before you can complete the final tax return. Late payment interest rules are not magically suspended, and the 2025/26 tax return due on 31 January 2027 still follows the old Self Assessment timetable.

From later years, the late submission system is points-based. HMRC’s current guidance says a missed quarterly update after 2026/27 can create a penalty point, with a £200 penalty once the relevant threshold is reached. Missing later submissions while at the threshold can bring further £200 penalties.

The sensible use of year-one relief is to learn the process without panic, not to build a backlog.

Sole trader versus landlord: where the first update differs

Sole traders and landlords both use Making Tax Digital for Income Tax, but their records are not identical.

Issue	Sole trader	Landlord
Main income	Sales, fees, commissions or other trading income	Rent and other property receipts
Common expense categories	Stock, travel, staff costs, office costs, professional fees	Repairs, finance costs, legal fees, management fees, travel
Multiple sources	Separate businesses may need separate updates	UK property, foreign property and jointly let property can need care
Private use	Common for vehicles, phones and home working	Common for mixed-use property costs or shared ownership
Year-end checks	Capital allowances, stock, accruals, private use	Finance cost restrictions, repairs versus improvements, joint ownership

Landlords should take extra care with repairs and improvements. Replacing a broken boiler is not the same tax question as adding a new extension. Sole traders should take extra care with mixed-use costs, mileage, stock and equipment. Both groups need evidence.

If you have more than one income source, the software setup matters. A sole trader business and a rental property business should not be mashed into one vague set of categories just because it looks simpler in the short term.

A simple month-by-month plan before 7 August

You do not need to wait until the quarter has ended.

When	What to do
Late April	Check whether you are in scope, confirm software, and set the update pattern
May	Reconcile April, fix bank feeds, agree categories and permissions
June	Reconcile May, review any property or mixed-use costs, chase missing receipts
Early July	Reconcile June or the 5 July cut-off, run the Q1 report, review odd items
Late July	Make corrections, check sign-in access, agree who presses submit
By 7 August	Submit the first quarterly update through compatible software

The phrase “agree who presses submit” sounds basic, but it matters. Some clients assume their accountant is filing. Some accountants assume the client is filing. Put it in writing, even if that is only a short email.

FAQ: MTD quarterly update 7 August 2026

Do I have to send an MTD quarterly update if I had no income in the quarter?

Yes, if you are in scope. HMRC says you still need to send a quarterly update if you have not received income or incurred expenses during the update period.

Does the first quarterly update mean I pay tax on 7 August 2026?

No. The update itself does not create a new tax payment deadline. You still need to manage Self Assessment payments, including any payments on account, under the normal timetable unless your circumstances change.

Can my accountant submit the quarterly update for me?

Yes, if the software, authorisation and agent setup are in place. Check this early because agent access problems are exactly the sort of boring admin issue that becomes painful in deadline week.

Can I correct an error after sending a quarterly update?

Yes. HMRC’s guidance says the update periods help corrections flow through the year. In practice, correct the digital record as soon as you find the mistake and make sure your next update reflects the corrected records.

Are landlords with jointly owned property treated differently?

They can be. HMRC says landlords with jointly let property can choose to include either all income and expenses for those properties, or only property income during quarterly updates. Expenses left out during the year still need to be reported before the annual tax position is finalised.

Is Golden Tree Consulting able to help with MTD setup before August?

Yes. We can check whether you are in scope, review your records, set up bookkeeping categories, and agree a quarterly filing process through our Self Assessment and bookkeeping work.

The best next step

Open your bookkeeping software this week and run a report for April so far. If the numbers look sensible, you have time to build the habit calmly. If they look wrong, you have found the problem early enough to fix it.

For clients in phase one, our recommendation is simple: treat 31 May 2026 as your internal clean-up date for April records, then review again at the end of June. By the time 7 August 2026 arrives, the first MTD quarterly update should feel like a short filing job, not a rescue mission.
