When are SSB monthly contributions due in Myanmar?

How SSB works for Myanmar employers

The Social Security Law 2012 requires employers to file the SSB monthly contribution return and pay both the employee 2% withholding and the 3% employer share by the 15th of the following month. The filing happens at the township SSB office for the workplace location, the same office that handles registration. The return covers wages paid in the immediately prior calendar month.

This SSB deadline aligns with the PIT remit deadline (also the 15th to IRD), so HR/payroll teams typically run a single "filings day" each month.

Monthly cycle at a glance

Day	Filing	Authority
7th	Monthly wages paid	Internal (Payment of Wages Law)
15th	SSB monthly return + contribution payment	Township SSB office
15th	PIT withholding remitted	IRD

Contribution rates and the wage-base cap

Item	Rate	Maximum (cap = MMK 300,000)
Employee contribution	2%	MMK 6,000 / month
Employer contribution	3%	MMK 9,000 / month
Total	5%	MMK 15,000 / month per employee

Worked example — March wages, April filing

An employer has 6 employees, each at MMK 800,000/month gross (above cap). For March wages:

Total monthly SSB per employee (capped)	MMK 15,000
Total team SSB for March	MMK 90,000
Filing + payment deadline	15 April
Late by even one day → penalty interest	From 16 April

Registration and monthly returns

• After month-end, finalise payroll: gross wages, 2% withholding, 3% employer share, capped at MMK 300,000 per IP.
• Prepare the SSB monthly return showing per-IP contribution and total payable.
• File at the township SSB office and pay (cash, banker's cheque, or approved bank transfer per local SSB office process).
• Keep stamped acknowledgements and payment receipts in a monthly SSB binder; retain for 7 years.
• If the 15th falls on a public holiday, file on the next working day.

Benefits SSB provides

• Medical (IP + registered dependants).
• Sickness cash benefit (after 1+ year of contributions).
• Maternity benefit — 14 weeks of paid leave with cash benefit through SSB.
• Work-injury (medical + temporary + permanent disability + survivors').
• Funeral grant.

Common variations

• Multi-site employers — file at each township office for that workplace's IPs; some firms consolidate at HQ township by special arrangement.
• Public-holiday clashes — file on the next working day; document the holiday on the receipt.
• Year-end amendments — adjust prior months via correction entries on the next monthly return.

Common SSB mistakes

• Waiting for the wage-payment confirmation before computing SSB — payroll closure should drive both.
• Filing late one month and rolling the arrears into the next month's payment without penalty calc.
• Submitting the return without payment receipt — both must reach the township SSB office.

Practical workflow for HR teams

Whether the SSB obligation in question is registration, contribution calculation, a benefit claim, or a leaver event, three operational habits prevent most non-compliance issues:

1. Anchor the SSB calendar to payroll close. The 15th of the following month is non-negotiable for the contribution return at the township SSB office. Treating SSB as a payroll-close output, not a separate task, eliminates last-minute filings.
2. Reconcile the SSB register against the payroll register monthly. Joiners enrolled within 30 days, leavers deregistered within 30 days, dependant changes captured — these are the three reconciliation lines that catch most defects before they become audit findings.
3. Cap discipline. Apply the MMK 300,000/month wage cap on every Insured Person, every month, before computing 2% / 3%. Most Myanmar SSB overpayments trace back to a payroll system that runs the rate against full gross.

Payslip transparency

Show the SSB withholding line distinctly on the payslip, alongside Personal Income Tax (PIT). Employees should see the 2% line item, the wage base it was applied to, and the SSB ID. Transparent payslips reduce employee queries about take-home pay and create a clean trail for any future SSB or IRD audit. Where the wage cap binds, label the line "SSB (capped at MMK 300,000 base)" so the maths is self-explanatory.

Multi-site coordination

For employers operating across more than one township, the township SSB office for the workplace — not the corporate head office — is the operational counterparty. Maintain a per-site SSB ledger covering: employer code, township office, monthly return file location, and copy of stamped acknowledgements. Centralised SSB tracking with site-level sub-ledgers is the simplest way to reconcile a multi-site monthly return. The same logic applies for PIT remittances to the IRD office covering the workplace.

Recordkeeping checklist

• Original employer registration acknowledgement.
• Per-IP enrolment forms with stamped SSB receipts.
• Dependant registration forms — track updates for life events (marriage, birth).
• Monthly contribution returns + payment vouchers (12 per year).
• Annual SSB summary return.
• Wage / service certificates issued on benefit claims.
• Deregistration acknowledgements for leavers.
• Penalty assessments and remediation correspondence (if any).

Retention rule: at least 7 years for SSB records, aligned with the payroll-record retention requirement under the Income Tax Law and the personnel-record requirement under ESDL.
