HMRC reminds taxpayers and agents that the second quarterly update deadline for MTD ITSA is 7 November 2026 for those with qualifying income over £50,000 who joined the mandate from April 2026. This covers the quarter ending 30 September 2026. HMRC has enhanced support arrangements including a dedicated MTD ITSA helpline, extended webchat hours, and a new “Digital Assistant” for common errors. The penalty soft landing (no late submission penalties for the first two years) applies, but late payment interest accrues from the due date. Agents are urged to ensure clients’ digital records are complete and software is updated to the latest API version.
Key Takeaways
- Quarterly Update Deadline and Scope: The 7 November 2026 deadline applies to the July-September 2026 quarter. Taxpayers must submit quarterly updates via MTD-compatible software, including income and expense categories aligned with HMRC’s specified chart of accounts. The final declaration (EOPS) is due by 31 January 2027.
- Enhanced HMRC Support Measures: The dedicated helpline (0300 200 3600) operates 8am-8pm weekdays. Webchat is available 9am-5pm. The Digital Assistant guides users through common validation errors such as mismatched turnover figures, incorrect expense categorization, and missing obligatory fields.
- Penalty Soft Landing and Interest Implications: While late submission penalties are waived for 2026/27 and 2027/28, late payment interest (currently 7.75%) applies from the quarterly payment due dates. Taxpayers should budget for quarterly tax payments to avoid interest accumulation.
