UK MTD Deadlines answers the recurring Making Tax Digital date questions for sole traders, landlords and VAT-registered businesses using GOV.UK guidance. itsa_mandation_check maps qualifying income for 2024-25, 2025-26 and 2026-27 to the April 2026, 2027 or 2028 start date. quarterly_update_dates lists the four update periods and the 7 August, 7 November, 7 February and 7 May deadlines for standard or calendar quarters, and next_quarterly_deadline finds the next one from a date. penalty_points_status compares missed submissions with the 4-point threshold and the GBP 200 penalty, and late_payment_penalty works out the percentage penalties on tax paid late for 2026-27 and 2027-28. vat_return_due_date applies the one calendar month and 7 days rule to a VAT period end, and mtd_calendar_draft builds a dated list, with an .ics text, for the owner to import. It reads and calculates only: nothing is submitted. Exemptions, interest rates, VAT penalties and payment-on-account dates are not modelled.
