Step-by-step calculation
This walk-through covers the penalty exposure when a Myanmar employer or individual misses a PIT remittance or filing deadline. Default: resident employer/employee, no special concessions claimed. The Myanmar Income Tax Law and prevailing IRD circulars impose interest on the unpaid tax plus a percentage penalty surcharge for late payment, late filing, or under-declaration. Tax year: 1 April – 31 March.
Step 1 — Identify the deadline that was missed
Most penalty exposure arises from one of three missed deadlines. The penalty quantum depends on which deadline, how late, and the cumulative tax involved.
| Filing / payment | Deadline |
| Monthly PAYE remittance + return | 15th of the following month |
| Annual employer reconciliation | By 30 June (within 3 months of 31 March) |
| Employee personal annual return | By 30 June |
| Tax assessment payment notice | Per IRD notice (typically 30 days) |
Step 2 — Apply the penalty bracket structure
The Income Tax Law and IRD circulars set a tiered structure. The principal exposures (subject to current IRD circulars):
| Failure type | Typical exposure |
|---|---|
| Late payment of tax | Interest on unpaid amount per the IRD's prevailing rate, accruing month by month |
| Late filing of return | Penalty surcharge (commonly 10% of tax under-paid; check current circular) |
| Under-declaration discovered on audit | Tax + interest + penalty up to 100% of tax under-declared in the most serious cases |
| Failure to withhold (employer) | Employer made personally liable for the unwithheld PAYE plus interest and penalty |
| Repeated default | Compounded penalty plus possible criminal sanctions for serious non-compliance |
Worked illustration — employer remitted MMK 1,200,000 of PAYE 60 days late. Assume 2% per month interest (illustrative; ) and a 10% surcharge for late filing:
| Component | Amount (MMK) |
|---|---|
| Tax due | 1,200,000 |
| Interest (illustrative 2% × 2 months) | 48,000 |
| Late-filing surcharge (10% illustrative) | 120,000 |
| Total payable | 1,368,000 |
Step 3 — Convert to remediation actions
- Pay the principal first to stop interest accruing.
- File the missing return to stop the surcharge growing.
- Apply for any waiver via formal letter to the IRD office where the default occurred.
- Document the cause — system failure, banking error — to support a waiver request.
What about SSB and the true net salary?
SSB has its own late-payment regime under the Social Security Law 2012 — typically 10% surcharge on overdue contributions. Employers can be doubly exposed (PIT and SSB) on the same payroll cycle if both filings are missed. Reconcile the PAYE return and the SSB return monthly to catch unreported employees on either side.
Employer takeaway
Lock the 15th-of-month PAYE remit and the 30 June annual reconciliation into a hard calendar reminder. Late PIT triggers interest plus a percentage surcharge under the Income Tax Law and prevailing IRD circulars; failure to withhold makes the employer personally liable. If a deadline is missed, pay the tax immediately, file the return, and apply for waiver only after both. Retain payroll, calculations, and IRD correspondence for at least 7 years.
Common variations to watch for
- Bank delays — IRD usually accepts proof of bank instruction date if the bank failed to clear; document carefully.
- System failure — keep IT incident logs to support a waiver request.
- Director liability — directors can be personally pursued for repeated failure to remit withholding.
- Voluntary disclosure — coming forward before audit usually attracts lower penalty than discovery.
- Group company structure — each entity files separately; don't centralise filings under a different TIN.
Common PIT mistakes to avoid
- Treating the 15th as a guideline — it is a statutory deadline; even one day late triggers exposure.
- Paying without filing — both must be done; partial compliance still triggers a late-filing surcharge.
- Failing to recover unwithheld PAYE from a leaver — employer pays out of pocket if PAYE was missed.
- Not reconciling SSB and PIT — each missed filing has its own penalty. See filing forms and correcting a PIT return.
