MTD quarterly deadlines

UK Making Tax Digital for Income Tax Self Assessment uses quarterly update periods in the tax year (6 April to 5 April). A typical year looks like:

  • Q1: 6 April – 5 July
  • Q2: 6 July – 5 October
  • Q3: 6 October – 5 January
  • Q4: 6 January – 5 April

Each open obligation in ComplyLet Pro shows the period and HMRC due date. Submit cumulative figures from your transactions for that income source. You cannot type totals directly into a submission.

Deadlines and fines are HMRC rules. Use the HMRC screen in the app for the dates that apply to your account.
