For a sole trader, MTD is a record-keeping and reporting workflow. The useful preparation is to establish which income is in scope, who maintains the records and whether the chosen software completes the required reporting steps.
Who is in the first group?
The first mandatory phase began on 6 April 2026 for eligible people with more than £50,000 qualifying income in 2024/25. HMRC’s agent toolkit explains the rollout and workflow. A later year’s turnover should not be substituted for the income year used in the eligibility test.
Combine qualifying self-employment and property income before expenses, with the adjustments and exclusions in HMRC’s calculation guidance. PAYE salary, dividends and pension income do not count towards this threshold. They may still need to be included in the annual tax return.
Later mandatory phases use more than £30,000 in 2025/26 for April 2027 and more than £20,000 in 2026/27 for April 2028. Check eligibility and exemptions before deciding that a headline turnover figure proves your position.
Make the records usable
Required digital records must exist before the relevant quarterly submission or its deadline, whichever is earlier. Recording promptly is good practice, not a rule that every transaction must be typed immediately. HMRC explains record content, retention and digital links in its record-keeping guidance.
ObvioTech recommendation: use a repeatable reconciliation process. Compare invoices and receipts with the bank record, explain unmatched transactions and correct errors through the supported workflow. A separate business account can help organisation, but this article does not present it as a universal MTD requirement.
Choose software by function
Check the exact product in HMRC’s software finder. Determine whether it supports your income sources, quarterly updates, annual return and agent arrangements. A familiar brand or VAT product is not sufficient evidence.
Integrated and spreadsheet-plus-bridging approaches can both be considered. Compare the supported digital links, correction process, exports, full recurring cost and help available. We have not established that most advisers prefer one route or that one vendor is the national adoption leader.
Separate quarterly and annual work
Quarterly updates are cumulative summaries. The standard 2026/27 deadlines are 7 August, 7 November, 7 February and 7 May; the latter two fall in 2027. Calendar-period elections and exact periods are covered by HMRC. The annual 2026/27 return is due by 31 January 2028 through compatible software.
Do not assume one update covers every business, or that each rental address is a separate business. Use the income-source guidance to identify separate sole trades and property businesses.
Check the handover to an agent
- Confirm registration and who authorises the software.
- Agree who enters records, resolves questions and submits each update.
- Retain submission confirmations and a recovery route if the usual operator is unavailable.
- Keep annual-return preparation and tax-payment checks on the calendar separately.
If HMRC has already enrolled you, follow its next-step instructions. If digital tools are unreasonable or impractical in your circumstances, check the exemption application process.
For 2026/27, late quarterly updates do not receive penalty points, but updates remain necessary and annual-return/payment obligations are separate. General information only; consult a qualified adviser for your own tax position.
