Step-by-step calculation
This walk-through assumes a Myanmar tax resident receiving a mix of monthly salary and various reimbursements. Default: single, no dependant allowances, no donations. Brackets are from the Union Tax Law 2025-2026 (Section 5). The core test for reimbursements: was the cost incurred wholly and exclusively for the employer's business, supported by an original receipt, and refunded at actual cost? If yes, the refund is not taxable salary. If any element fails — round-sum, no receipt, personal benefit — the amount is salary. Tax year: 1 April – 31 March.
Step 1 — Apply the 20% basic personal relief
Strip out genuine reimbursements first. Only assessable salary (base + allowances + recharacterised reimbursements) goes through the relief calculation. The 20% basic personal relief is capped at MMK 10,000,000/year.
| Annual base salary | (figure) |
| Plus: round-sum / undocumented "reimbursements" (recharacterised) | (figure) |
| Plus: taxable allowances (housing, transport, etc.) | (figure) |
| Less: genuine receipted business reimbursements | excluded |
| = Annual gross assessable salary | (sum) |
| Less: 20% basic personal relief | − up to MMK 10,000,000 |
| 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 — base salary MMK 1,000,000/month, plus a "round-sum entertainment allowance" of MMK 200,000/month with no receipts. The allowance is recharacterised as salary:
| Item | Annual MMK | Treatment |
|---|---|---|
| Base salary | 12,000,000 | Taxable |
| Round-sum entertainment allowance | 2,400,000 | Taxable (recharacterised) |
| Receipted client-meeting reimbursements | 1,800,000 | Not taxable |
| Annual gross assessable | 14,400,000 | |
| Less: 20% relief | (2,880,000) | |
| Taxable | 11,520,000 |
Run MMK 11,520,000 through the bands: 0% on first 2M (0) + 5% on next 8M (400,000) + 10% on next 1,520,000 (152,000) = annual PIT MMK 552,000.
Step 3 — Convert to monthly withholding
- Monthly PAYE: MMK 552,000 ÷ 12 = MMK 46,000/month.
- Genuine receipted reimbursements: processed outside payroll, no PAYE.
- Round-sum / undocumented: processed through payroll with PAYE.
What about SSB and the true net salary?
SSB follows PIT logic: only assessable wages count toward the MMK 300,000/month wage base. Genuine receipted reimbursements are excluded from SSB. Recharacterised round-sum allowances feed into the wage base but the cap (max MMK 6,000 employee, MMK 9,000 employer) typically already binds.
| Monthly gross assessable | MMK 1,200,000 |
| Less: PIT | − MMK 46,000 |
| Less: SSB (employee, 2% on cap) | − MMK 6,000 |
| Plus: receipted reimbursement (refund of out-of-pocket) | + MMK 150,000 |
| Monthly cash to employee | MMK 1,298,000 |
Employer takeaway
Reimbursements are tax-free only when they (a) refund actual costs, (b) are supported by original receipts, and (c) were incurred wholly for business. Round-sum allowances, "monthly reimbursements" without receipts, and personal-benefit refunds are taxable salary — withhold PAYE and add to the SSB base. Remit PIT to IRD by the 15th of the following month, reflect classification on the annual reconciliation by 30 June, and retain receipts and the expense policy for at least 7 years.
Common variations to watch for
- Mobile phone reimbursement — receipted business calls are non-taxable; flat monthly amount is taxable salary.
- Travel reimbursement (per diem) — reasonable per-diem within IRD-accepted norms may be non-taxable; excess is salary.
- Client entertainment — receipted with attendee log is non-taxable; round-sum is salary.
- Home internet — generally treated as personal benefit unless contract is in employer's name.
- Petrol card / fuel allowance — receipted business mileage is non-taxable; flat fuel allowance is salary. See transport allowance tax.
Common PIT mistakes to avoid
- Calling a salary supplement a "reimbursement" — IRD looks at substance, not the payslip label.
- Accepting receipts in employee's name for personal items — fails the business-purpose test.
- Bundling receipts for a year-end "reimbursement" — periodicity matters; refund close to actual incurrence.
- Forgetting the SSB knock-on — recharacterised allowances raise the wage base. See SSB and PIT interaction.
