When this lands in your year.

Filled squares are this service’s own filing dates. Faint squares are everything else the calendar tracks — which is what a month actually looks like when this is only one of the things you owe.

Who this applies to

This service covers 3 of the 34 obligations we track. Each one below states exactly which entity types it binds and at what turnover, taken from the same rule set the checker runs on.

What it costs to get wrong

We do not publish penalty figures. Interest, late fees and prosecution thresholds turn on facts we do not have and on notifications that move, and a wrong number on a Chartered Accountant’s own website is worse than no number.

What we can tell you exactly is the exposure. Leave this service unhandled and these 3 filings go unfiled — all of them annual, which is why they tend to be discovered late. Where each one falls in the year is on the FY calendar.

These are the obligations we track for the standard statutory position. Sector rules, state-level professional tax and one-off events can add to them, and extensions can move a date. Ask us before relying on this for a filing.
