MTD Add or Cease Income Sources UK 2026/27 — What to Tell HMRC

If you are already using Making Tax Digital (MTD) for Income Tax and start or stop a sole-trader or property-income source, update HMRC through your online services account or your agent services account. The correct next step depends on whether the source is new, whether one source has stopped while another continues, and whether all relevant sources have stopped.

Do not assume that closing one property or changing a trading name automatically ends the MTD obligation. Tell HMRC the source-specific facts, complete any outstanding updates for a source that has ceased, and still submit the tax return for the year in which the income stopped. The MTD Calculator→ can help map the reporting cycle, but it cannot change an HMRC account or decide whether a property business has legally ceased.

When you start a new income source

A new source can be a new sole-trader activity or a new property-income source. First check that your compatible software can report it. Then add the source to your HMRC online services account, or ask your agent to use the agent services account, and provide details such as the start date.

HMRC's default sequence is important: you normally include the new source in a tax return first, then begin creating its digital records and sending quarterly updates after that return has been submitted. For example, if a new source starts during 2026/27, it is normally included in the 2026/27 tax return before that source enters the later MTD reporting cycle.

HMRC also allows an individual to choose to report a new source from the date the income starts. That is an optional earlier route, not a reason to send records for a source that has never been added to the HMRC account. After adding it, check that the source appears in your software; a refresh or reconnection may be needed.

When one source stops

Ceasing a source means the self-employment has stopped trading or you have stopped receiving income from the relevant property source. Tell HMRC the date it ended through the online services account or agent services account by the quarterly-update deadline for the period in which it stopped.

You must complete all outstanding quarterly updates for that source for the period when it was active. The ceased source is still included in the tax return for the tax year in which it stopped. You should keep the records that support the final update and the annual return.

If another sole-trader or property source continues, the continuing source remains in MTD. You must keep creating digital records and sending quarterly updates for it. Stopping one rental property does not necessarily end a property business when other properties remain rented; check the property-business facts before telling HMRC that all property income has ceased.

When all relevant sources stop

If every source of self-employment and property income has ceased, tell HMRC the date of cessation and send the final quarterly update for the period that contains that date. You must still include the ceased income in the tax return for that tax year and submit that return using MTD-compatible software.

After the tax year in which the income stopped, HMRC says you will not need to use MTD for Income Tax. You still need to keep the digital records supporting the return for the applicable record-retention period. Ending MTD is therefore not the same as deleting the records or skipping the final return.

Changes that are not MTD income-source changes

If you stop receiving employment income, a pension, dividends or savings interest, HMRC says you do not normally need to add or cease that item in the MTD online account. Report the change through the tax return for the year in which it stopped.

Likewise, adding a new partnership share, company income or employment does not make it a new sole-trader or property source. It may still need to appear in the annual tax return, and your software must support the information required before you submit that return.

Source, business and property are not interchangeable labels

Before selecting “add” or “cease”, identify what HMRC means by the source. A sole trader may change the type of work, trading name, premises or customer without creating a new source. A landlord may sell one property while continuing the same property business. Conversely, a genuinely separate activity or property-income source may need its own record and reporting treatment. The online account should reflect the facts, not the way a bookkeeping application happens to display a category.

Keep the legal owner and activity description beside the start or cessation date. If a business is transferred to a company, partnership or another person, record the transfer date and the final transactions of the original owner. Do not use the incorporation date as a convenient software clean-up date unless it matches the tax and ownership facts. The annual return may need income and disposal information even after the original MTD source has ended.

The final update and the annual return

The final quarterly update is not the same as the final tax return. The quarterly update reports the source information for the relevant period; the annual return brings together the full tax-year figures, adjustments, reliefs and other income. Reconcile the final update to the records and then include the source in the tax return for the year in which it stopped.

If a source stopped partway through a quarter, record the actual cessation date and the transactions up to that date. Check whether invoices received later relate to the active period and how the accounting basis treats them. Do not omit a final receipt because the business bank account was closed or because the software source was archived.

Software and agent controls

MTD-compatible software does not automatically update the HMRC source record. After making the account change, refresh the connection and check that the correct source identifier, start date or cessation date appears in the software. If an agent files the update, ask for a copy of the confirmation and verify that the authorisation covers the right tax service.

Keep a change log with the person who made the update, date and time, source affected, evidence used and confirmation reference. If the source is duplicated, missing or shown with the wrong date, stop sending duplicate data and contact HMRC or the agent. Correcting a source in software alone does not correct an HMRC account.

What to do when the facts are uncertain

A temporary vacancy, seasonal trading pause, late invoice or change of letting agent may not be a cessation. Write down the facts and expected next step before changing the status. If the source may restart, preserve the records and ask HMRC how it should remain active. If ownership, partnership status or incorporation is involved, obtain advice before selecting a date that changes the reporting obligation.

Do not use the MTD account as a substitute for a cessation notice required under another tax process. VAT, PAYE, Corporation Tax, partnership and Self Assessment obligations can have separate registrations and deadlines. Closing an MTD Income Tax source does not close every HMRC account or remove a tax return obligation.

Review the source after submission

After adding or ceasing a source, save the HMRC confirmation, final update, annual return and payment or submission receipt. Compare the source list in the online account with the software and the bookkeeping records. At year end, review whether any source was omitted, duplicated or left active after it ended. This review should happen before the next quarterly deadline, not only when HMRC sends a query.

Where the taxpayer uses an agent, the taxpayer should still retain independent access to the source list and the records. Confirm that the agent's software is connected to the intended account and that the final update was accepted rather than merely queued. If more than one agent has worked on the records, establish which agent is responsible for the final update and annual return.

If a source is added late, do not manufacture quarterly figures from a bank total without reconciling the underlying records. Mark the period that needs correction, identify any missing transactions and ask HMRC or the agent how the update should be brought up to date. The source's reporting status and the accuracy of its figures are separate controls. Keep the correction evidence with the final submission receipt.

Save the corrected records before sending another update.

Keep the confirmation reference with them.

Before closing the case.

A practical checklist

Before changing your MTD account, record:

• the source type and legal owner;
• the date the activity or rental income actually began or ended;
• whether another sole-trader or property source continues;
• the last quarterly update that covers the active period;
• the tax return in which the new or ceased source will first appear; and
• the software or agent account that will send the update.

If the source has been sold, transferred to another owner, incorporated or stopped only temporarily, do not select a cessation date just to remove it from a software screen. Keep the contracts, invoices, rent records and correspondence that explain the change, and use HMRC's account route or professional advice where ownership or cessation is unclear.

The Four Dates to Reconcile

When a source changes, keep four dates separate: the date the activity began or ended, the date it was added or ceased in the HMRC account, the period covered by the final quarterly update and the date the annual return was submitted. They may be different. A late account update does not move the underlying income into a different tax year, and archiving a software feed does not prove that the final update was accepted.

For a transfer or incorporation, also record the legal owner before and after the change, the last invoice or rent receipt of the original source, and any asset or stock transaction that belongs in the annual return. A new company’s bookkeeping account should not be used to overwrite the original sole-trader records. Preserve the closing trial balance and explain how amounts received after cessation relate to the earlier activity.

After the change, run a source-status review before the next quarterly deadline. Compare HMRC, the agent account, compatible software, bank records and the annual tax-return draft. Resolve duplicate sources, missing identifiers and wrong dates through the official route. If the source status is uncertain, retain it with a documented explanation and seek confirmation; selecting “ceased” only to suppress a software warning can create a larger reporting error.
