What separates a clean Singapore HR function from a messy one is rarely talent — it is calendar discipline. The MOM compliance calendar looks unremarkable until you miss an Employment Pass renewal window, get a quota recount mid-quarter, or file an IR21 late. Each of those individually carries fines, applicant-side disruption, and audit risk that scales quickly when a company has more than ten foreign employees.
This article lays out the year in the order it actually happens — month-by-month, with the MOM, IRAS and CPFB filings that hit each window, and the operational triggers (renewals, terminations, transfers) that do not align to a calendar but always need to be ready. It is written for HR managers, founder-CFOs and corporate-secretarial teams running Singapore Pte Ltds with foreign-employee headcount.
The figures and dates below are calibrated to the regulatory state as at May 2026. Per MOM, the qualifying salary for new Employment Pass applications is SGD 5,600 monthly for non-financial sectors and SGD 6,200 monthly for Financial Services as at 1 January 2026; the S Pass qualifying salary will rise from SGD 3,300 to SGD 3,600 (services) and SGD 3,800 to SGD 4,000 (financial services) effective 1 July 2026.
The Year in the Singapore HR Compliance Calendar
Some filings are date-fixed: monthly CPF, monthly foreign worker levy, IR8A by 1 March, ECF by AGM. Other obligations are trigger-fixed: pass renewal 60 days before expiry, IR21 minimum one month before employee departure, internal transfer notification within stipulated windows. The MOM compliance calendar is the union of both — fixed dates plus operational triggers tracked alongside.
January
New Employment Pass qualifying salary thresholds take effect on 1 January annually — for 2026, SGD 5,600 (non-financial) and SGD 6,200 (Financial Services) per MOM. HR teams should re-audit any new offers in the pipeline against the new floors. Levy rates and quota ratios for the year are also confirmed by 1 January. CPF contribution rates for the year are published by the Central Provident Fund Board (CPFB) and applied from the first January payroll for citizen and PR employees.
February
Annual filing of IR8A returns commences. Per IRAS, employers must file the IR8A (employee earnings) form by 1 March of each year for the preceding calendar year. Employers in the Auto-Inclusion Scheme (AIS) — mandatory for employers with five or more employees — submit IR8A electronically through the IRAS portal. See IRAS Auto-Inclusion Scheme.
March
1 March is the IR8A filing deadline. Employers also typically pay performance bonuses in March for the preceding calendar year — bonuses count toward total wages for CPF computation purposes (for citizens and PRs) up to the Annual Wage Ceiling. ECI (Estimated Chargeable Income) for the company itself is also typically filed in this window if the financial year ends 31 December — though that is a corporate-tax filing, not an HR one.
April
Personal income tax filing for employees opens. Per IRAS, individual income tax returns are due by 18 April (e-Filing) or 15 April (paper) for the preceding year of assessment. Employers under AIS have their employees’ employment income pre-filled — but expat employees with overseas income, rental income or stock-based compensation often need additional disclosures. HR’s role is to make sure that IR8A, IR8S (where applicable) and Appendix 8A/8B are accurate and filed in time.
May–June
Mid-year is the right window to audit pass-renewal pipelines for H2. Employment Pass renewals must be filed at least 30 days before expiry, but professional practice is to start at 60 days. Renewals filed in June are processed against H2 of the year’s qualifying salary thresholds — material because S Pass salary thresholds rise on 1 July 2026 from SGD 3,300 to SGD 3,600 (services) and SGD 3,800 to SGD 4,000 (financial services). HR teams running S Pass headcount should run a wage audit by end-May to identify employees who need a salary uplift before the new floor bites.
July
1 July 2026: new S Pass qualifying salary thresholds take effect. Any S Pass renewal filed after 1 July is assessed against the new SGD 3,600 / SGD 4,000 floors. Quota and levy ratios for S Pass and Work Permit holders should be reviewed against the company’s local-employee headcount — the Dependency Ratio Ceiling for services-sector S Pass is 10 per cent of total workforce per MOM; for manufacturing it is 18 per cent; construction and process up to 20 per cent for S Pass.
August–September
Quarterly internal review window. Pass-renewal audit for Q4-expiring passes (file by end-October at latest). Quota recompute against any local-employee headcount changes (resignations, hires, conversions). Foreign worker levy reconciliation against actual headcount and tier mix. Workplace Fairness Act 2026 obligations — including grievance handling and anti-discrimination policy review — are best aligned to a mid-year cadence rather than year-end.
October
Q4-expiring Employment Pass renewals must be filed by end-October to clear MOM processing safely. COMPASS scoring for renewals is recomputed against the latest data — for the underlying scoring framework, see our COMPASS framework 40-points guide. Renewals that fall short trigger appeals — see our why your work pass appeal failed in Singapore for the playbook.
November–December
Year-end run. CPF contribution-rate review for the upcoming January transition. Bonus accrual computation. IR8A data preparation. Year-end terminations trigger IR21 tax clearance — per IRAS, employers must file Form IR21 at least one month before the employee ceases employment or departs Singapore, and must withhold any monies due to the employee until tax clearance is received. See IRAS tax clearance for foreign employees.
The Operational Triggers (Not Calendar-Fixed)
Several obligations within Singapore HR compliance do not align to dates — they fire when an event happens. Calendar discipline matters for these because the trigger window is short.
Pass Renewals: 60 Days Before Expiry
Per MOM, Employment Pass renewals can be filed up to six months before expiry. Best practice is to file at 60 days. Earlier filing rarely accelerates outcome; later filing creates risk if MOM requests additional documentation. The renewal calendar should sit on a separate sheet with employee, pass type, expiry date, target file date, and current COMPASS score.
Internal Transfers and Job Title Changes
Per MOM, changes in job title, role or salary that are material must be notified via the EP Online portal within stipulated windows — typically before the change takes effect for substantive changes, and within a short window thereafter for administrative changes. Failure to notify can affect the next renewal application.
Termination and Cancellation
When a foreign employee’s employment ends, the employer must cancel the Employment Pass within seven days of cessation per MOM rules. Failure to cancel exposes the employer to continued levy or salary-disclosure obligations. IR21 must be filed at least one month before departure, and withholding applies to final salary until tax clearance is received from IRAS.
Work Injury, Workplace Safety, Workplace Fairness Act
Work-injury claims under the Work Injury Compensation Act must be reported to MOM within 10 days of becoming aware. The Workplace Fairness Act 2026 introduces grievance-handling, retaliation-prohibition and anti-discrimination obligations — companies with ten or more employees must have a documented grievance procedure. The trigger is the grievance, not the calendar.
The Five Most Common Compliance Misses
From practical experience, the five compliance misses that most often surface in MOM and IRAS audits are: (1) Employment Pass not cancelled within seven days of termination; (2) IR21 filed less than one month before departure, triggering withholding-and-release confusion; (3) S Pass quota over-utilised because local-employee headcount drops were not reflected in DRC computation; (4) job-title or salary changes for EP holders not notified before the next renewal, with COMPASS score recomputed against outdated data; (5) IR8A filed late or with incorrect Appendix 8A benefits-in-kind.
Each individual miss is small. Stacked across a portfolio of 20 to 50 foreign employees over a calendar year, they create the audit footprint that triggers MOM’s deeper-dive reviews.
Tooling: Spreadsheet, HRIS, or Outsource
Companies with under 25 foreign employees can run a compliance calendar in a structured spreadsheet — tabs for fixed dates (IR8A, levies), pass-renewal pipeline, internal-transfer log, termination log. Companies with 25–100 foreign employees benefit from a proper HRIS with renewal alerts and integration to the EP Online portal where MOM permits API access. Companies with 100+ foreign employees typically outsource compliance to a specialist or to corporate-secretarial firms — see Singapore Secretary Services for the corporate-secretarial side and Raffles Corporate Services for end-to-end accounting, payroll and compliance.
For HR teams running the compliance calendar in-house, the levy mechanics and sectoral quota maths are covered in our Singapore foreign worker levy 2026 by sector piece. The Employment Pass renewal mechanics — including COMPASS recomputation — are in our complete Singapore Employment Pass guide 2026.
Conclusion: Calendar Discipline Is Cheaper Than Audit Discipline
The MOM compliance calendar is not glamorous, but the cost difference between a clean year and a messy year is often the cost of one lost EP renewal — fees, agency cost, lost productivity, and the candidate-side relationship damage. HR functions that run a structured calendar with operational-trigger overlays catch the problems before they become MOM letters. Functions that react to renewals as they expire end up running everything as a fire drill.
