Step-by-step stock-option tax calculation in Myanmar
Walk-through assumes a resident employee receiving employer or parent-company stock options or RSUs. Myanmar's Income Tax Law treats equity compensation as assessable salary income at the taxable event. All amounts in MMK after conversion.
Step 1 — Identify the taxable event
| Instrument | Typical Myanmar taxable event |
|---|---|
| Non-qualified stock option (NQSO) | At exercise — spread between FMV and exercise price |
| RSU (Restricted Stock Unit) | At vesting — full FMV of vested shares |
| ESPP discount | At purchase — discount portion treated as wages |
| Subsequent disposal | Capital gains tax (separate from PIT) |
Step 2 — Compute the assessable amount in MMK
| Item | Calculation | Example |
|---|---|---|
| FMV at taxable event (USD) | e.g. 1,000 shares × USD 50 | USD 50,000 |
| Exercise / strike price (USD) | e.g. 1,000 × USD 10 | USD 10,000 |
| Spread (USD) | FMV − Exercise | USD 40,000 |
| Central Bank rate (event date) | e.g. MMK 4,200/USD | 4,200 |
| Assessable income (MMK) | Spread × rate | MMK 168,000,000 |
Step 3 — Apply UTL brackets and PAYE
Add the spread to year-to-date assessable income, recompute annual PIT, and withhold PAYE in the event month. The 20% basic personal relief and dependent allowances apply against total annual taxable income (relief cap MMK 10M).
| Annual taxable income | Marginal rate |
|---|---|
| MMK 0 – 2,000,000 | 0% |
| MMK 2,000,000 – 10,000,000 | 5% |
| MMK 10,000,000 – 30,000,000 | 10% |
| MMK 30,000,000 – 50,000,000 | 15% |
| MMK 50,000,000 – 70,000,000 | 20% |
| MMK 70,000,000+ | 25% |
Capital gains on subsequent disposal
When the employee later sells the shares, the gain (sale price − FMV-at-event) is treated as capital gain under Myanmar's separate capital gains tax regime — not as salary income. Different rates and filings apply.
Employer takeaway
Stock options and RSUs are taxed at the taxable event (exercise / vesting), not at grant. Convert the spread (or full FMV for RSUs) to MMK at the Central Bank rate on the event date, add to YTD assessable income, recompute annual PIT, and withhold PAYE in the event month. Remit to IRD by the 15th of the following month. Capital gains on later disposal are taxed separately. Retain grant agreements, vesting schedules, and FMV evidence for 7 years.
Variations on stock-option income
- RSUs — taxed at vesting on full FMV.
- ESPP discount — taxed at purchase on the discount portion.
- Non-resident expat — flat 25% on Myanmar-source equity income (Myanmar-source typically means earned for work performed in Myanmar).
- Tax equalisation by employer — common for assignees; gross up the spread so net matches home country.
- Foreign assignment income — see foreign-assignment income.
Common stock-option tax mistakes
- Taxing at grant rather than at exercise / vesting.
- Using year-end FX rate instead of Central Bank rate on event date.
- Failing to withhold PAYE on the spread because cash didn't move.
- Confusing the salary-income taxable event with the later capital-gains event.
