How Vietnam Personal Income Tax Works
Vietnam's Personal Income Tax (PIT) is governed by the Law on Personal Income Tax No. 04/VBHN-VPQH and applies to employment income, business income, capital gains, rental income, and other sources. For employment income -- the most common category -- Vietnam uses a progressive tax system with seven brackets ranging from 5% to 35% on monthly taxable income. Tax residents receive a personal deduction of 11 million VND per month and a dependent deduction of 4.4 million VND per registered dependent per month, significantly reducing the effective tax rate for most workers.
Vietnam's tax system is relatively favorable compared to regional peers. According to PwC Vietnam's Pocket Tax Book, the top marginal rate of 35% applies only to monthly taxable income exceeding 80 million VND (approximately $3,200 USD). For context, the average monthly salary in Vietnam is approximately 7-10 million VND in 2025-2026, meaning most workers fall within the 5-10% brackets. Vietnam's economy has grown at approximately 6-7% annually over the past decade, with average wages increasing roughly 8-10% per year, putting upward pressure on the tax brackets that have not been adjusted since 2020.
How Vietnam PIT Is Calculated
The monthly PIT calculation follows these steps:
Taxable Income = Gross Income - Social Insurance (10.5%) - Personal Deduction (11M VND) - Dependent Deductions (4.4M VND each)
Tax is then calculated by applying progressive rates to each bracket of taxable income:
Worked example: Monthly gross income of 30 million VND with 1 dependent. Social insurance = 30 x 10.5% = 3.15M (but this calculator takes pre-deduction income). Taxable income = 30 - 11 (personal) - 4.4 (1 dependent) = 14.6M VND. Tax = (5 x 5%) + (5 x 10%) + (4.6 x 15%) = 0.25 + 0.5 + 0.69 = 1.44M VND/month. Effective rate = 1.44/30 = 4.8%. Annual tax = 17.28M VND.

Vietnam PIT Bracket Reference Table
The following table shows Vietnam's progressive PIT brackets for employment income, as established by the Law on Personal Income Tax and unchanged since the 2020 deduction update:
| Monthly Taxable Income (VND) | Tax Rate | Tax on Bracket | Cumulative Tax |
|---|---|---|---|
| Up to 5,000,000 | 5% | 250,000 | 250,000 |
| 5,000,001 - 10,000,000 | 10% | 500,000 | 750,000 |

Practical Examples
Example 1 -- Junior office worker: Monthly gross income of 15 million VND, no dependents. Taxable income = 15 - 11 = 4 million VND. Tax = 4 x 5% = 200,000 VND/month (2.4 million/year). Effective rate = 1.3%. This worker barely pays tax due to the generous personal deduction.
Example 2 -- Mid-career professional: Monthly gross income of 40 million VND, 2 dependents. Taxable income = 40 - 11 - 8.8 = 20.2 million VND. Tax = (5 x 5%) + (5 x 10%) + (8 x 15%) + (2.2 x 20%) = 0.25 + 0.5 + 1.2 + 0.44 = 2.39 million VND/month. Effective rate = 6.0%.

Example 3 -- Expat executive: Monthly gross income of 100 million VND, 1 dependent. Taxable income = 100 - 11 - 4.4 = 84.6 million VND. Tax = 0.25 + 0.5 + 1.2 + 2.8 + 5.0 + 8.4 + (4.6 x 35%) = 18.15 + 1.61 = 19.76 million VND/month. Effective rate = 19.8%. Compare this with the Poland income tax calculator for a European comparison.
Tips and Strategies for Vietnam PIT
- Register all eligible dependents: Each dependent saves 4.4 million VND/month in taxable income. At the 20% bracket, that equals 880,000 VND/month in actual tax savings per dependent. Ensure timely registration with your employer or tax office.
- Maximize social insurance deductions: The 10.5% employee contribution is fully deductible. If you have voluntary insurance contributions or charitable donations to approved organizations, these may also be deductible.
- File annual finalization if beneficial: If you overpaid withholding tax (common with bonuses or irregular income), the annual finalization allows you to claim a refund. The deadline is March 31.
- Understand non-resident implications: If you are an expat who does not meet the 183-day residency threshold, you pay a flat 20% with no deductions -- which can be higher or lower than the progressive rate depending on income level.
- Track bracket creep: Vietnam's PIT brackets have not been inflation-adjusted since 2014 (deductions last updated in 2020). As wages rise with Vietnam's 6-7% annual GDP growth, more income falls into higher brackets each year.
- Consider tax treaties: Vietnam has double tax agreements with over 80 countries. If you are a foreign worker, check whether your home country's treaty with Vietnam provides relief from double taxation.
Frequently Asked Questions
What are the 2026 Vietnam Personal Income Tax brackets?
Vietnam uses seven progressive monthly PIT brackets for employment income: 5% on the first 5 million VND, 10% on 5-10 million VND, 15% on 10-18 million VND, 20% on 18-32 million VND, 25% on 32-52 million VND, 30% on 52-80 million VND, and 35% on taxable income above 80 million VND per month. These brackets apply to taxable income after deducting the personal deduction (11 million VND/month) and dependent deductions (4.4 million VND per dependent per month). The brackets have remained unchanged since 2014 under Law on Personal Income Tax No. 26/2012/QH13.
What is the personal deduction amount in Vietnam?
Vietnamese tax residents receive an 11 million VND monthly personal deduction (132 million VND annually), which is subtracted from gross income before applying tax brackets. Each registered dependent allows an additional 4.4 million VND monthly deduction (52.8 million VND annually). These deduction amounts were last increased by Resolution No. 954/2020/UBTVQH14 in July 2020, raising the personal deduction from 9 million to 11 million VND and the dependent deduction from 3.6 million to 4.4 million VND. There have been ongoing discussions about further increases to account for inflation, but no changes have been enacted as of early 2026.
Who is considered a tax resident in Vietnam?
You are a Vietnamese tax resident if you meet any of these criteria: you are present in Vietnam for 183 days or more in a calendar year or in 12 consecutive months from your first day of arrival; you have a registered permanent residence in Vietnam; or you have rented accommodation in Vietnam for 183 days or more in a tax year and cannot prove tax residence in another country. Tax residents pay progressive rates from 5% to 35% on worldwide income. Non-residents pay a flat 20% on Vietnam-sourced employment income and 0.1% on securities transfer income, with no personal or dependent deductions.
What are the mandatory social insurance contributions in Vietnam?
Vietnamese employees contribute 10.5% of gross salary to mandatory insurance: 8% for social insurance, 1.5% for health insurance, and 1% for unemployment insurance. These contributions are deductible before calculating PIT. Employers contribute an additional 21.5% on top of gross salary: 17.5% for social insurance, 3% for health insurance, and 1% for unemployment insurance. The social insurance contribution base is capped at 20 times the base salary (currently 36 million VND per month). Foreign workers are also required to contribute to social insurance starting from December 2018 under Decree 143/2018/ND-CP.
What counts as a dependent for Vietnam PIT purposes?
Dependents eligible for the 4.4 million VND monthly deduction include: children under 18 regardless of circumstances; children aged 18-22 who are full-time students with no income or income below 1 million VND per month; disabled children of any age who cannot work; parents, parents-in-law, siblings, and grandparents who are of retirement age without a pension, or who are disabled and unable to work, or who earn below 1 million VND per month. Each dependent can only be claimed by one taxpayer. Registration with the tax authority is required, and you must provide supporting documents such as birth certificates, student ID cards, or disability certificates.
When is the Vietnam PIT annual finalization deadline?
The annual PIT finalization deadline is the last day of the third month following the end of the calendar year -- typically March 31. Employees with income from a single employer who have had tax properly withheld are not required to file a finalization return. However, those with income from multiple sources, freelance income, or who wish to claim additional deductions must file. Employers must finalize PIT for their employees by the same March 31 deadline. Late filing incurs penalties starting at 2 million VND, with additional interest on any tax underpayment at 0.03% per day.
