BRITVEX ADVISORY LTD | Practical MTD for Income Tax troubleshooting

Quick answer: If your Making Tax Digital (MTD) quarterly update is showing as missing, pending, failed or not submitted, do not assume that clicking Send completed the process. Check the submission status inside your compatible software, then check the recent activity in your HMRC online account. HMRC says a successfully sent update should appear there as “You sent a quarterly update.” If the record is missing, identify which self-employment or property source and update period is affected, resolve the software or authorization problem, and submit the outstanding update. If the figures are wrong, correct the digital records rather than inventing a second set of accounts.

This guide is for sole traders, landlords and their authorized agents using MTD for Income Tax. It focuses on failed submissions and record recovery. It is not a general introduction to MTD for VAT and it does not replace the broader Britvex Making Tax Digital service or our complete MTD rules guide.

The first five checks when an MTD quarterly update is missing

Before changing your accounting data, take these steps in order:

1. Identify the obligation. Confirm the tax year, quarterly update period and whether it belongs to a sole-trade business or a property business. A person with both may need separate updates.
2. Read the software status. Look for a genuine HMRC-accepted or successful submission status, not merely an internal “ready,” “queued” or “sent for approval” label. Labels differ by provider.
3. Check HMRC recent activity. Sign in using the MTD Income Tax details and look for the message “You sent a quarterly update.” HMRC provides this wording in its official guidance.
4. Preserve evidence. Record any software transaction reference, submission time, error details, screenshots and the affected source. Do not publish Government Gateway credentials or sensitive personal information in support tickets.
5. Resolve the cause and send the update. Depending on the problem, you may need to renew software authorization, finish digital records, select the correct business source or ask the software supplier to investigate a transmission error.

A discrepancy between the software and HMRC should be treated as a status-check problem, not automatic proof that a penalty is due. If you cannot verify receipt after normal processing, contact your software provider with the submission details. HMRC’s guide to sending quarterly updates explains what HMRC expects and how recent activity is displayed.

How to confirm HMRC actually received the update

Step 1: inspect the correct tax year and business source

Start in the software account that has been linked to MTD for Income Tax. Check that you have selected the actual person and the correct income source. A sole trader with consultancy income and a separate UK property business should not assume that successfully transmitting one update has satisfied both obligations. For someone with multiple property activities, confirm how the software organizes the relevant property business according to HMRC’s source rules.

Review the period-end setting too. Standard updates and permitted calendar updates have distinct period ends, although their usual quarterly deadlines are the same. Once you have sent your first update, you generally cannot switch update-period type for the rest of that tax year. A wrongly selected period can cause a reporting mismatch even where all transactions are present.

Step 2: distinguish software events from HMRC acceptance

The words draft, ready, waiting for approval, queued, failed, rejected and completed are not interchangeable. Many systems include their own workflow before attempting an HMRC submission. A bookkeeping dashboard showing “Complete” may simply mean that transactions were reconciled. A job shown as “sent” may still require an acceptance or receipt check. The specific confirmation screen and error interpretation are product-specific; HMRC directs users to their provider for that part of the process.

Find the submission log or activity record if the product offers one. Note the tax reference or MTD account being used, the update period, the source, the timestamp and the result. A software acknowledgment and an HMRC online-activity entry together provide better evidence than a screenshot of a button being clicked.

Step 3: check the HMRC online account

According to HMRC, after a quarterly update is sent the recent activity in the MTD for Income Tax online account should show “You sent a quarterly update.” Look in the account associated with the person’s actual MTD registration. If you use an agent, coordinate the check securely and make sure the agent has the appropriate authorization.

Do not infer from the absence of an instant screen refresh that an update failed: first confirm whether the software has issued an acceptance and whether the correct account and period are being viewed. If there remains a discrepancy, ask the software supplier to investigate the submission result and then escalate through HMRC’s published MTD support route as appropriate.

MTD update problem: symptom, likely cause and safe next action

These are diagnostic categories, not official HMRC error codes. Never claim an error code has a universal meaning without checking your software provider’s current documentation.

A rejected quarterly update: the recovery process

Verify MTD registration and software authorization

Compatible accounting software must be authorized to communicate with HMRC. A client may have registered for MTD but never finished connecting the software, or the authorization may have expired. HMRC says software authorization normally needs to be renewed every 18 months. Check the product’s “Connect to HMRC” or equivalent area and use the official authentication process rather than sharing Government Gateway passwords with a third party.

Where an accountant is filing, the agent should use the firm’s agent services account credentials and ensure the required client authorization is in place. An existing Self Assessment agency arrangement and the software’s MTD connection should not be assumed to be identical technical steps. HMRC’s software setup guidance explains the authorization and accounting-period requirements.

Verify the income source and update-period configuration

Check whether the software is attempting to file self-employment data, UK property data or a separate business source. Verify the income source is active in the MTD account and that the period selected matches the permitted update-period method. A sole trader who also receives property income cannot fix a missing property update by resending the sole-trade totals under a different label.

If the software imported records from a spreadsheet or another application, confirm the import has not accidentally created duplicate businesses, switched the tax year or allocated a transaction to an incorrect source. Do not delete an existing source or reset an MTD account simply because a submission failed; resolve the account structure first.

Validate the digital records without rewriting the history

Your software needs the digital income and expense records that underlie the cumulative update. Reconcile sales invoices, bank receipts, rental receipts, expenses, refunds, fees and business/private splits. A missing bank feed or duplicated payment may materially distort the income and expense totals even if the software is capable of transmitting them.

For more on building a reliable record trail, see Britvex’s digital record-keeping service and bookkeeping and reconciliation support. The aim is to fix the accounting evidence, not to make numbers match a target by posting arbitrary journal entries.

Escalate with a useful evidence pack

A useful support request contains the software product and version, whether it concerns the individual or an authorized agent, the affected income source, the update period, the exact error text, the attempted submission time and whether HMRC recent activity shows an entry. Include screenshots that redact credentials, full bank details, National Insurance numbers and other unnecessary identifiers. Ask the software supplier whether HMRC accepted, rejected or never received the submission. If the supplier identifies an HMRC account problem, use the official support service with the reference they provide.

What if you missed an MTD quarterly update deadline?

The immediate priority is to restore accurate digital records and submit the outstanding update. A missed date does not make the records disappear or convert the quarterly update into an annual tax return. However, the penalty position depends on the tax year and the person’s status.

Under HMRC’s published first mandatory tax-year concession (2026–27), no quarterly-update late-submission penalty points are applied for that tax year. The quarterly updates are still required before the MTD annual tax return can be filed. Late annual tax-return penalties, relevant late-payment penalties and late-payment interest are separate matters. For later mandatory years, HMRC’s points-based quarterly-update rules apply, with a four-point threshold and a £200 penalty at the threshold, subject to the detailed provisions. Do not assume a missed quarterly update always produces an immediate £200 charge, and do not assume the concession continues indefinitely.

If you are volunteering to use MTD, the quarterly-update penalty treatment differs from a person who is required to use it. Check HMRC’s current penalty guidance before making a decision. This legal context appears inside the article because it matters; we deliberately keep years out of the article’s evergreen title and URL.

Priority order after a missed deadline

1. Check that MTD for Income Tax actually applies to the person and period. A person may have been looking at a VAT obligation or a prior-year Self Assessment deadline instead.
2. Reconcile the records through the relevant quarter-end and check source-level obligations.
3. Send the outstanding quarterly update using compatible software, retaining confirmation evidence.
4. Confirm receipt in HMRC recent activity and record any remaining unsubmitted source.
5. Continue the digital record-keeping process for the next quarter and prepare the annual return separately.

Our older MTD quarterly deadline article explains the deadline that recently passed. This guide is different: it is a reusable recovery process for a missing or failed update, regardless of which quarter created the problem.

Incorrect figures in an accepted update: correct the records, not the past by guesswork

HMRC’s MTD for Income Tax quarterly updates are cumulative. Each one totals the digital records from the beginning of the tax year through that update period. That makes the process materially different from sending four independent, final quarterly returns.

Suppose a sole trader submits the first quarterly update and later discovers that an allowable expense was omitted. HMRC explains that the digital record should be corrected and the next cumulative update will reflect the revised year-to-date figures. You generally do not need to resend an earlier quarterly update merely because an error was discovered, although special action can be necessary after the fourth update.

Worked example: a missing expense found after the first update

Assume the following illustrative amounts, all from the same self-employment business:

This £37,650 is a simple accounting difference for illustration, not the final taxable profit or the income tax due. Capital allowances, adjustments, other income, tax bands, finance-cost rules and reliefs may need to be considered later. The key operational point is that the second update should draw on the corrected digital records, including the omitted £650 expense from the earlier period.

Do not simply adjust a headline number in the quarterly-update screen if doing so leaves the underlying digital records incorrect. The ledger, bank and supporting document trail should agree, so later summaries and the eventual annual return are not built on incompatible figures.

What changes after the fourth update?

HMRC explicitly provides cases where the fourth quarterly update may need to be resent after changes to digital records—for example, correcting an error or adding relevant jointly let property expenses and certain Rent-a-Room amounts. This should be handled before making the appropriate annual tax and accounting adjustments in the software. Do not describe every record correction as “just wait for the next quarter” if the fourth update has already been submitted.

Missing transactions and duplicated bank entries: a practical reconciliation workflow

A digital quarterly update is only as reliable as the transactions behind it. Common business issues include bank feed disconnections, card receipts recorded twice, gross income being confused with net payment-processor receipts, mileage or home-office costs being classified without evidence, and rental deposits recorded incorrectly as income.

A sensible monthly process is to import the bank and sales data, reconcile opening and closing bank balances, inspect unmatched entries, review credit notes and refunds, flag personal transactions, test the expense categories and retain underlying invoices or statements. For landlords, distinguish property income from capital receipts and repairs from improvements. These judgments may affect the annual tax return even where the quarterly update itself is an unadjusted record summary.

If an earlier item is discovered, correct the date and category in the appropriate digital record, retain an explanation of the correction and check how the software reflects it in the next cumulative update. Where a supplier’s integration has duplicated data, correct the duplicated records once—do not blindly delete bank transactions before establishing which entry is the proper accounting source.

Two businesses, one person: how missing updates occur

A frequent source of confusion is a taxpayer who is both self-employed and a landlord. MTD for Income Tax generally requires quarterly updates for each relevant self-employment and property business source, even though the person eventually completes one annual tax return. HMRC also expects updates where there is no income or expense activity in an update period.

Consider a consultant with a sole-trade business and rental property. Their software may show “quarterly update complete” for consultancy while the property source remains outstanding. If they check only the tax-year summary screen, it may appear that everything has been submitted. Before closing the matter, review each source and quarter separately.

For jointly let property, HMRC permits specific choices about including property income and expenses in quarterly updates; certain expenses excluded from earlier updates must be brought into the record after year-end, including by resending the fourth update where required. Do not apply a default all-or-nothing property-expense rule without checking the jointly let property instructions. See HMRC’s quarterly-update guidance.

A nil quarter still needs attention

No trading activity does not necessarily mean no quarterly filing. HMRC says that where the relevant business has no income and no expenses during an update period, a quarterly update is still required to tell HMRC. That is different from a taxpayer who is genuinely outside MTD or has properly ceased the business.

For a quiet period, verify that the business source is still active, reconcile the digital records to nil activity and submit the update through the software. If the business has genuinely ceased or income sources have changed, follow the relevant HMRC add-or-cease income-source process rather than repeatedly sending nil updates without checking the account position.

Software connection problems: what to check before changing products

Switching software immediately after one failure may make the audit trail harder to follow. First check software compatibility for MTD for Income Tax, not merely MTD for VAT; whether the account is signed up; whether its authority to HMRC is current; whether the right tax year and accounting period are configured; and whether all software products are linked properly when records move between them.

HMRC says records created in one software product and used in another for MTD submissions require appropriate digital links. Manual rekeying or copying figures between systems may break the required digital-record chain in relevant circumstances. Some providers include bridging functionality for supported spreadsheet-based workflows, but it must actually meet the requirements and submit through the MTD service. HMRC’s digital-record guidance covers multi-product software and digital links.

If the software product itself is incompatible or no longer supported, assess the replacement and how historical records and submission evidence will be preserved before migration. Britvex’s MTD services can be quoted together with bookkeeping support where the engagement calls for both.

MTD Income Tax versus MTD VAT: do not troubleshoot the wrong system

The abbreviation “MTD” is used for different regimes. MTD for VAT covers VAT returns, digital VAT records and VAT-specific submission obligations. MTD for Income Tax covers the self-employment/property digital records, quarterly updates and the annual Income Tax return. A VAT return displayed as accepted does not prove that an Income Tax quarterly update has been sent, even if both are managed using the same accounting platform.

Likewise, the first-year MTD Income Tax quarterly-update penalty concession does not automatically apply to missed VAT Returns. If your immediate problem is a VAT submission, start with the VAT registration, VAT return period, VAT-specific software authorization and HMRC’s separate VAT rules. Britvex’s MTD service page explains the two systems, and our accountancy services cover the connected record and filing processes.

Why the tax estimate does not match your final liability

After submitting updates, HMRC and compatible software can show an estimated tax position based on year-to-date data and other income HMRC knows about. That estimate is not a certified final tax computation. It may exclude income that has not been added, tax adjustments, reliefs, capital allowances, pension and Gift Aid information, losses or other relevant facts.

HMRC’s annual MTD tax-return workflow remains necessary to add or check other income and gains and make appropriate adjustments before submission. The usual final tax-return deadline is 31 January after the relevant tax year. A previous tax year’s Self Assessment return may still need filing under the prior method even though the taxpayer has started using MTD. See the Britvex Self Assessment service and HMRC’s annual MTD tax-return guide.

When should you ask an accountant to investigate?

Professional help is especially useful where the submission is not traceable, the taxpayer has multiple relevant income sources, a software migration has broken digital links, rental accounting is mixed with self-employment accounts, or missing bank entries have accumulated over several quarters. If an HMRC notice or penalty is involved, its precise tax, period, issue date and statutory grounds should be checked rather than assuming it relates to the quarterly update.

Britvex’s practical MTD recovery review

A defined engagement can include checking MTD registration and agent authorization, reviewing the software connection, reconciling the relevant period’s records, identifying unsent source-level obligations, helping resolve provider errors and preparing submissions within the agreed scope. Tax-return adjustments and other services can be scoped separately rather than assumed to be included in a software troubleshooting fee.

Frequently asked questions: missing or rejected MTD quarterly updates

1. How do I know if HMRC received my MTD quarterly update?

Check the submission outcome in your compatible MTD for Income Tax software and the recent activity in your HMRC MTD online account. HMRC says successful activity is recorded as “You sent a quarterly update.” If the two systems appear inconsistent, keep the evidence and ask your provider to trace the submission.

2. My software says “sent” but HMRC shows nothing. Should I send again?

Not blindly. Verify that the software’s status represents an accepted submission, then check the correct MTD tax year, business source and HMRC account. If receipt is unclear, get the provider’s submission reference and resolve the status before attempting to send another copy.

3. Does an MTD quarterly update have to be filed if I had no income?

Yes, where the relevant MTD business source remains active and the quarter has no income or expenses, HMRC says you must still submit an update to report that position. A genuinely ceased business or an out-of-scope person needs a different assessment.

4. What happens if I miss a quarterly-update deadline?

Submit the outstanding update as soon as the digital records are accurate. Penalty treatment depends on the applicable tax year and whether MTD is mandatory or voluntary. HMRC’s 2026–27 concession removes late quarterly-update penalty points for that year, not the reporting requirement or every other penalty.

5. Can I correct a mistake in a previous quarterly update?

Yes. Correct the underlying digital record promptly. Because quarterly updates are cumulative, a later update generally reflects corrected earlier entries. After the fourth quarterly update, HMRC describes circumstances in which that final update should be resent.

6. Do I have to resubmit the first quarter after finding a missing receipt?

Usually the correction is made to the digital records and included in the next cumulative update. Do not assume that a separate resubmission is always required. Check HMRC’s special guidance if the fourth update has already been sent or your software reports an exception.

7. Can a sole trader with rental property send one combined quarterly update?

No single consolidated update automatically replaces the obligations for separate relevant business sources. HMRC generally requires an update for each self-employment and property business source, even though one annual tax return brings the overall tax position together.

8. Why is my MTD quarterly update rejected after connecting my software?

Possible reasons include account authorization, selection of the wrong source or period, or software validation and transmission problems. Only the actual provider/HMRC response can identify the cause in a particular case. Preserve the exact error message and request a provider-level trace.

9. Does using accounting software automatically mean I am MTD compliant?

No. It must be compatible with the relevant MTD regime, properly connected to HMRC and used to maintain the required digital records and send the appropriate submissions. Multi-product workflows may also require digital links.

10. Does an MTD quarterly update mean I must pay Income Tax every quarter?

No. A quarterly update is a summary of digital income and expense records, not a new quarterly tax payment bill. Annual tax-return and existing payment rules still matter, including payments on account where relevant.

11. Can my accountant submit a missing MTD update for me?

An appropriately authorized agent can assist using compatible software, subject to the agreed engagement and the accuracy of the supplied records. The client and agent should first establish which obligations are missing and who is responsible for completing them.

12. Where can I get help correcting records and sending an outstanding MTD update?

You can request an MTD recovery and bookkeeping quote through Britvex’s enquiry form. Existing clients can use the secure portal. Britvex will assess the software, records, source-level reporting position and appropriate filing scope.
