The first Making Tax Digital for Income Tax quarterly update is due on 7 August 2026. It applies to sole traders and landlords who are required to use MTD from April 2026, generally because their qualifying self-employment and property income exceeds £50,000.
For accounting practices, the immediate challenge is clear: client records must be sufficiently complete and digitally maintained before the quarterly update can be submitted through compatible software.
When several clients are behind on bookkeeping, asking an already stretched team to work longer hours is rarely a sustainable solution. The practice needs to assess the backlog, prioritise urgent cases and introduce additional capacity quickly.
What Does the 7 August Deadline Cover?
The first quarterly update summarises income and expenses recorded for the opening period of the 2026-27 tax year.
Depending on the reporting basis selected, it generally covers:
- 6 April to 5 July 2026 under standard update periods; or
- 1 April to 30 June 2026 under calendar update periods.
Quarterly updates are summaries of digitally recorded income and expenses. They are not tax returns, and tax or accounting adjustments are not normally required before submission.
First, Establish the Size of the Backlog
Do not treat every incomplete client file as equally urgent.
Prepare a central list showing:
- Whether the client is within MTD for Income Tax;
- Which income sources require updates;
- The last completed bookkeeping month;
- Whether bank accounts are reconciled;
- Which documents remain outstanding;
- Whether compatible software is ready; and
- Who is responsible for completing and reviewing the work.
This turns an unclear backlog into a manageable action plan.
Prioritise Clients by Filing Risk
A simple three-tier system can help practices direct resources effectively:
| Priority | Client position | Required action |
|---|---|---|
| Tier 1 | MTD applies and records are substantially incomplete | Begin work immediately |
| Tier 2 | Most records are processed but reconciliations or documents remain outstanding | Complete gaps and review |
| Tier 3 | Records are substantially complete or the client is outside the immediate deadline | Monitor and schedule |
Start with clients who are within the MTD rules and have the largest bookkeeping gaps. Lower-risk files can be completed as capacity becomes available.
Request Missing Information Immediately
Send each affected client a specific list of outstanding items rather than a general request for “all bookkeeping records.”
The request may include:
- Missing bank statements;
- Sales and purchase invoices;
- Expense receipts;
- Property income and expenditure records;
- Loan or finance statements;
- Details of private or mixed-use expenditure; and
- Explanations for unidentified transactions.
Set an internal cut-off date before 7 August so that the team has time to process, reconcile and review the information.
Check Software and Digital Records
MTD quarterly updates must be submitted using compatible software. Practices should confirm that each client:
- Is properly signed up for MTD for Income Tax;
- Has the correct income sources recorded;
- Is using compatible software;
- Has selected the appropriate update periods;
- Maintains the required digital records; and
- Has authorised the practice to act where necessary.
Each update covers figures from the start of the tax year to the end of the relevant update period. This means corrections to earlier records can generally be reflected in the next cumulative update.
What Happens If the Deadline Is Missed?
HMRC has confirmed that it will not apply penalty points for late quarterly updates during the 2026-27 tax year.
However, this should not be treated as permission to ignore the deadline. Clients must continue maintaining digital records, and the required quarterly updates must be submitted before their annual tax return can be completed through the MTD process. From later tax years, missed quarterly deadlines will fall within the points-based penalty system.
Late completion can also create operational problems, including:
- Larger backlogs for the next quarter;
- Less reliable tax estimates;
- Increased pressure on year-end work;
- Repeated client follow-ups; and
- Reduced confidence in the practice’s compliance processes.
Add Capacity Instead of Extending Working Hours
Recruiting and training permanent bookkeepers may take too long when a statutory deadline is approaching.
Outsourced bookkeeping support can provide additional capacity for:
- Posting outstanding transactions;
- Processing invoices and expenses;
- Completing bank and credit-card reconciliations;
- Identifying missing records;
- Reviewing nominal ledger balances;
- Organising digital bookkeeping records; and
- Preparing files for final review and MTD submission.
The UK accounting practice should retain responsibility for reviewing the completed records, confirming the client’s position and authorising the submission.
