How is bonus calculated in Myanmar?
Bonuses in Myanmar are not mandated by statute; the formula sits in the employment contract or company policy. Common bases are one month's basic (Thingyan / year-end), a percentage of annual basic for performance, or a per-target piece value. All bonuses are fully taxable as PIT assessable income in the month paid, with PAYE grossed up.
What Myanmar law says
Myanmar statute does not prescribe a bonus formula. The Employment & Skills Development Law 2013 treats bonus as a contractual benefit: enforceable if in the contract, handbook, or established practice. Most employers fall into one of three patterns:
- Thingyan / year-end bonus — one month's basic, paid in April or at FY-end (1 April – 31 March is the Myanmar tax year).
- Performance bonus — a percentage of annual basic tied to KPI achievement, paid post-appraisal.
- Sales / piece-rate bonus — a per-target or per-unit amount, paid monthly or quarterly.
All bonuses are fully taxable PIT assessable income in the month paid. PAYE must be grossed up — not bracket-stacked across months. SSB applies up to the MMK 300,000/month wage-base cap.
Calculation — three common formulas
Employee on MMK 500,000/month basic; annual basic = MMK 6,000,000.
| Bonus type | Formula | Amount (MMK) |
|---|---|---|
| 13th-month / Thingyan | 1 × monthly basic | 500,000 |
| Performance @ 10% annual basic | 10% × 6,000,000 | 600,000 |
| Performance @ 15% annual basic | 15% × 6,000,000 | 900,000 |
| Sales bonus, MMK 50,000 × 8 targets | 50,000 × 8 | 400,000 |
Documentation requirements
- Contract clause or written policy stating eligibility, formula, timing, pro-rating.
- Payslip itemising bonus separately from basic, OT, and allowances.
- PIT withheld and remitted to IRD by the 15th of the following month.
- Record retention: at least 7 years.
Edge cases
- Pro-rating new joiners — typically by completed months in the qualifying year.
- Resigned mid-year — most policies require employment on the pay date; check contract.
- Terminated for cause — bonus typically forfeited per contract.
- Discretionary bonus paid year after year — can become legally enforceable through custom and practice.
- SSB — bonus counts toward the wage-base in the month paid, capped at MMK 300,000.
- Bonus in foreign currency — convert to MMK at the Central Bank reference rate on the payment date.
Employer takeaway
Myanmar bonuses follow contract, not statute. Document the formula clearly (one month basic, % of annual basic, or per-target) and pro-rating rules. Treat bonuses as fully taxable PIT income in the month paid, gross up PAYE on the marginal rate, remit to IRD by the 15th, itemise on payslip, and retain records 7 years. Repeated discretionary payments can create binding precedent.
Common payroll mistakes
- Forgetting to gross up PAYE in the bonus month and under-withholding.
- Treating bonus as not subject to SSB — it counts toward the MMK 300,000 cap.
- Paying bonus net-in-hand and skipping the payslip line.
- Treating "discretionary" as a permanent escape hatch — see 13th-month enforceability.
- Not pro-rating leavers per the policy and triggering a Final Settlement dispute (see final settlement).
- ESDL 2013 — contractual benefit enforceability
- Union Tax Law 2025-2026 — PAYE on lump-sum payments
- Payment of Wages Law — payslip itemisation
