The second Making Tax Digital quarterly update, covering 6 July to 5 October, is due 7 November. HMRC has confirmed no penalty points apply for late quarterly updates this tax year, which is a genuinely useful grace period, and also a trap if it makes the deadline feel optional.
It isn't. The quarterly updates are short summaries, not full tax returns, but the value of doing them properly has nothing to do with HMRC's enforcement timetable. It's about building the habit of digital records all year round, so that by the time penalties do apply, filing on time is just what you already do, not a new skill you're learning under pressure.
Our take: treat this deadline as if the forgiveness isn't there, because next year it won't be.
