Step-by-step calculation
This walk-through explains both the standard instalment mechanism (PAYE) and the discretionary IRD payment plan that may be requested for assessed tax. Default: Myanmar tax resident employee, single, no dependant allowances, no donations. Brackets are from the Union Tax Law 2025-2026 (Section 5). Tax year: 1 April – 31 March.
Step 1 — Apply the 20% basic personal relief on the consolidated annual figure
The instalment regime starts from a properly calculated annual PIT — the 20% basic personal relief and any allowances reduce gross to taxable income before the brackets are applied. The annual figure is then divided into twelve monthly instalments via PAYE.
| Annual gross salary | (figure) |
| Less: 20% basic personal relief | − up to MMK 10,000,000 |
| Less: spouse / child / parent allowances | 0 in default case |
| Annual taxable income | = residual |
Step 2 — Apply the Union Tax Law 2025-2026 brackets
| Annual taxable income | Marginal rate |
|---|---|
| 1L – 20L (MMK 0 – 2,000,000) | 0% |
| 20L – 100L (MMK 2,000,000 – 10,000,000) | 5% |
| 100L – 300L (MMK 10,000,000 – 30,000,000) | 10% |
| 300L – 500L (MMK 30,000,000 – 50,000,000) | 15% |
| 500L – 700L (MMK 50,000,000 – 70,000,000) | 20% |
| 700L & above (MMK 70,000,000+) | 25% |
Worked illustration — an employee with annual PIT of MMK 1,200,000:
| Mechanism | How it pays |
|---|---|
| Standard PAYE instalments (employer withholds) | 12 × MMK 100,000/month, due by the 15th of each following month |
| Annual return top-up (multi-employer / freelance income) | Single payment with the 30 June return; IRD may agree to a short instalment plan on application |
| Audit assessment instalments | Discretionary; written application stating reason, proposed schedule, and security if requested |
Step 3 — Convert to monthly withholding
- PAYE instalment: MMK 100,000/month, remitted by the 15th of the following month.
- Top-up at 30 June: single payment unless instalment plan agreed.
- Audit assessment: per IRD-approved schedule with interest on outstanding balance.
What about SSB and the true net salary?
SSB is itself a monthly instalment regime — 2% employee + 3% employer on the wage base capped at MMK 300,000/month (max MMK 6,000 employee, MMK 9,000 employer). There is no annual lump-sum SSB option; contributions are due monthly to the Social Security Board.
| Annual PIT | MMK 1,200,000 (paid as 12 × MMK 100,000 PAYE) |
| Annual SSB (employee, max) | MMK 72,000 (paid as 12 × MMK 6,000) |
| Annual SSB (employer, max) | MMK 108,000 (paid as 12 × MMK 9,000) |
Employer takeaway
PAYE is the structural instalment system: divide annual PIT by 12 and remit each month by the 15th of the following month. For top-up tax on the annual return, pay in full by 30 June; if cashflow blocks this, file a written instalment request to the IRD before the deadline. Interest still accrues on the outstanding balance. Retain PAYE schedules, instalment correspondence, and proof of payment for at least 7 years.
Common variations to watch for
- Top-up tax for multi-employer staff — usually paid as a single sum with the 30 June return. See second-job tax.
- Self-employed quarterly instalments — separate from PAYE; freelancers and sole proprietors may have estimated payment obligations. See freelancer PIT.
- Audit assessment — instalment plans are discretionary; submit a clear cashflow plan.
- Mid-year salary cut — adjust PAYE downward; a refund may be claimed on the annual return.
- Final paycheck for leavers — clear all outstanding PAYE before release.
Common PIT mistakes to avoid
- Skipping the monthly remit and paying at year-end — triggers interest and the late-filing surcharge. See penalties for late PIT.
- Assuming an instalment request stops interest — interest still accrues until the balance is cleared.
- Combining PAYE and SSB into one payment — the two have different bank accounts and forms.
- Forgetting to inform IRD when cashflow improves — pay early to reduce interest cost.
