Give yourself some breathing space
Your records need to reach us ahead of HMRC's deadline. We agree your cut-off dates during onboarding, so there is time to ask questions and deal with missing information.
If you have already missed an update, get in touch promptly. We check what is outstanding and agree any catch-up work before taking it on.
For 2026/27, HMRC is not issuing late-submission penalty points for quarterly updates. You must still keep digital records and send the updates before submitting your annual tax return. Read HMRC’s penalty guidance. Checked 4 November 2026. Source: HMRC: send quarterly updates. Alternative calendar periods are available; confirm the setup used in your software.
