The snapshot
In-house tax and finance leads already know the year has repeating dates: payroll taxes, value added tax, withholding, the corporation tax return, and the local obligations that do not sit in the same notice. The miss is rarely ignorance of the month. It is a date that moved, a person who left, or a new activity — an import, a branch, a contractor — that never got a line on the list.
The calendar worth keeping is short, named, and tied to the person who files.
The trap
The list lives in one officer’s head, with a reminder on their phone. They travel in the week a return is due. Someone else logs into the portal, cannot find the workings, and either files late or files a figure that does not match the ledger. The penalty arrives. The workings are rebuilt after the fact.
The obligation was known. The handover was not.
This is an illustration, so the point can be said out loud. It is not a client matter.
What belongs on the list
For each obligation, four fields are enough:
- What is filed, and to whom.
- The date, and what happens if the period falls on a weekend or the portal is down. Write the internal date a few days earlier.
- Who prepares, who reviews, and who has the login. A login that only one person can use is a single point of failure.
- Where the workings live, so the figure can be tied to the ledger without starting again.
Build the year from the entity you actually are. A company with employees, a company that charges VAT, a company that withholds on suppliers, and a company that only holds a trading licence are not the same calendar. Add a line when the activity starts. Do not copy another entity’s poster.
Rates and due dates change. The calendar should say who checks the authority’s notice, and how often. A date copied from last year’s diary is a date that can be wrong. This note does not set those dates for you. The return in front of you does, read against the current notice.
What to do
- If you lead finance: put the internal deadline, the preparer, and the reviewer on the same list. A date with no name will be missed by everyone.
- If you prepare the return: keep the workings with the acknowledgement. The portal receipt is not the calculation.
- If you are new in the seat: walk last year’s filings before you trust the diary you inherited. Look for obligations that were paid and never written down.
- If you sit with the directors: ask which filing depends on one person. That is the one to cover before they take leave.
