Tax Filing for New PRs: What's Different in Your First Year

Quick answer: Filing itself works the same way it does for a Citizen — same portal, same rates, same deadline — but there's one genuinely PR-specific rule worth knowing before you need it: if you resign, are let go, or leave Singapore for more than three months, your employer is required to file a tax clearance (Form IR21) and withhold your final pay until that clearance comes through. Citizens are exempt from this entirely; PRs and foreign employees are not. New PRs, who are statistically more likely to be job-hopping or considering a move in their first couple of years, are exactly the group most likely to run into this without expecting it.

Getting into the system for the first time

If this is your first year filing as a tax resident, you'll typically receive a Notice to File (or be auto-included if your employer participates in the Auto-Inclusion Scheme, which most do) and file through IRAS's myTax Portal using your Singpass — the same login you already use for ICA and CPF matters. There's no separate "new PR" registration step; your first filing happens the same way any tax resident's does, based on income earned in the preceding calendar year.

The IR21 rule — the one genuinely different piece

Here's the mechanic: when a non-Citizen employee (this includes every PR) ceases employment, goes on overseas posting, or plans to leave Singapore for more than three months, their employer must file Form IR21 with IRAS — generally at least one month before the employee's last working day or departure date, whichever comes first. From the moment the employer knows about the impending departure, they're required to withhold all monies due to the employee — salary, unused leave pay, allowances, bonuses, the lot — until IRAS issues tax clearance. Citizens never trigger this process at all; it exists specifically because PRs and foreigners can leave the tax jurisdiction in a way a Citizen effectively can't.

There's a practical exception: if you're a PR ceasing employment with one employer but staying in Singapore rather than leaving, your employer can instead obtain a Letter of Undertaking from you confirming you don't intend to leave permanently — no IR21, no withholding. This is the situation that applies to most new PRs simply switching jobs within Singapore, so it's not something to be alarmed about generally — but it's worth actually confirming this is how your employer is handling your resignation, rather than assuming it, particularly if you're planning any trip longer than three months around the same time you resign.

Why this catches new PRs specifically

A new PR who resigns to take a better offer, or who's planning an extended trip home around a job change, is precisely the profile this rule was built around. If your employer files an IR21 because you're leaving Singapore for an extended period, expect your final pay to sit with them until tax clearance is issued — which can take a number of weeks — rather than landing in your account on your usual last-pay date. Planning your finances around that gap, and having the conversation with HR early about which path (IR21 vs. Letter of Undertaking) applies to your specific situation, avoids an unpleasant surprise.
