What cannot wait in the first week

A resignation from a one-person HR or payroll seat does not hand you a quarter to plan a transition, or even the length of whatever notice they serve. It hands you a week before the first dated obligation lands, sometimes less, and several more stacked inside the weeks after that. Our guide on losing your only HR person covers the full sequence: access, the bank file, the handover, interim cover. The narrower question inside it is the one that actually determines whether the first fortnight goes badly. Of everything on that longer list, what genuinely cannot slip past day seven?

The honest answer is fewer things than a worried founder usually assumes, and a different set of things than most generic resignation checklists list first.

One person holding several government logins

In a team small enough to run HR through a single hire, that person is usually also the sole Corppass Administrator, the one who remembers the CPF EZPay habits from month to month, and the address IRAS and MOM correspondence quietly defaults to. None of that transfers by handover email or a shared password document sitting in a drawer. It has to be reassigned through the actual government channel, and at least one of the deadlines below is already running whether anyone in the building has noticed yet or not. The risk is not that any single step is hard. It is that a company can look perfectly fine, right up until the CPF EZPay login stops working two weeks after everyone stopped thinking about it.

The five things that cannot wait

These are the five, roughly in the order their deadlines bite:

1. Corppass Administrator access. If the departing employee held sole Admin rights, the entity must not be left without one: GovTech’s guidance is to keep at least one Corppass Administrator at all times, and an entity with none for 30 days is suspended, cutting off CPF EZPay, myTax Portal and MOM’s work pass eServices in the same stroke. Your Registered Officer can appoint a replacement Administrator, or remove the departed one directly with their Singpass. Do this first: nothing else on this list is reachable without it.

2. This month’s CPF contribution. A change of hands does not move the date. Contributions are still due on the last day of the calendar month, and CPF Board’s enforcement threshold sits at the 14th of the following month, which is not the same thing as the due date. Miss it and interest runs at 1.5% a month, minimum S$5, from the day after the due date, not from the 15th.

3. Salary, on the Employment Act’s own clock. MOM’s rule allows 7 days from the end of the salary period, and sooner if the resignation itself is the final pay run being processed. Non-payment of salary is an offence under the Act, and whose job it normally was to press pay is not a defence.

4. The itemised payslip that goes with it. It must be issued together with the payment, or within 3 working days if that is genuinely not possible. MOM’s stated practice on a first lapse is to engage the employer and allow a month to start complying; a repeat lapse after that can draw an administrative penalty of up to S$400.

5. Any IR21 already in motion. If a foreign or Permanent Resident employee elsewhere in the business is also leaving, or has already gone, Form IR21 is due to IRAS at least one month before their last day or before they leave Singapore, and all monies due to them have to be withheld from the date the company became aware of the departure until IRAS issues a Clearance Directive. Filing late, or not at all, can draw a fine of up to S$5,000.

That is the list we secure first when we step into a resignation gap in the first week. The order matters: access before anything else, since nothing further down the list is reachable without it, then the obligations with the shortest fuse. Work pass renewals, leave records nobody has reconciled in a year, the vendor logins only one person ever used: none of that carries a day-seven deadline, and all of it still has to happen. The shortlist covers the week. It does not cover the quarter.

Why IR21 belongs on a domestic resignation’s checklist

It is easy to assume Form IR21 only matters when the HR person themselves is a foreign hire. It does not work that way. A one-person HR function is usually also the one tracking every other foreign or Permanent Resident employee’s status: whose Employment Pass renewal is due, who handed in notice the same month, who is relocating overseas for longer than three months. If any of that was mid-process when the resignation landed, the one-month lead time to IRAS keeps running regardless of who is watching it, and a missed IR21 is a separate offence from anything to do with the HR person’s own departure. Checking the tracker, even a rough one kept in a spreadsheet, belongs in week one.

What can wait a little longer

Not everything a departing HR person leaves behind carries the same weight. Rewriting the employee handbook, renegotiating a benefits provider, or auditing years of leave balances can sit for a few weeks without a regulator, a bank or an employee noticing. The difficult part is telling the two categories apart while the person who normally made that judgement call is the one who has just left, which is exactly when the five above tend to get treated as equally postponable. They are not, and the cost of being wrong about which category something falls into is not evenly spread either: a stale handbook goes unnoticed, and a missed CPF due date does not.

If nobody left has done this before

None of the five above is complicated in isolation. What makes the first week hard is that they usually lived in one person’s head, next to the passwords, the bank contact, and the knowledge of which employee’s work pass is up for renewal. A founder, general manager or finance lead covering HR for the first time is rarely short on competence. What they are short on is the specific muscle memory of having filed a CPF contribution before, or knowing that a failed Direct Debit fails quietly rather than loudly, days before anyone checks the bank feed.

Covering the week, or running it yourself

We step into exactly this gap through interim HR cover and payroll processing: access reassigned properly, this month’s CPF contribution filed on time, salary and its payslip out on the Employment Act’s clock, and any live IR21 tracked to its date, while you recruit a permanent replacement without the deadline pressure attached to the search. Or take the five above, put the dates on someone else’s calendar this afternoon, and manage the week in-house. Handed over or handled in-house, a bad week is survivable. Leaving the list for a fortnight, hoping the next pay run sorts itself out on its own, is not.
