Laos Personal Income Tax Guide 2026

Overview — Tax Department of Lao PDR

The Tax Department of Lao PDR administers all tax matters under the Tax Law of Lao PDR. Laotian tax residents are taxed on Lao-source income; non-residents are taxed only on Lao-source income. Tax residency is determined by physical presence of 183 days or more in a calendar year or having a habitual residence in Laos. Employees have tax withheld at source by their employer. The Tax Department has progressively modernised tax administration through online filing systems.

PIT Tax Brackets 2026

Laos applies a progressive monthly bracket system for Personal Income Tax with a top rate of 25%. For 2026, the monthly brackets are as follows:

• 0% — on monthly salary up to LAK 1,300,000 (approx. USD 65)
• 5% — on the next LAK 3,700,000 (LAK 1,300,001–5,000,000)
• 10% — on the next LAK 10,000,000 (LAK 5,000,001–15,000,000)
• 15% — on the next LAK 10,000,000 (LAK 15,000,001–25,000,000)
• 20% — on the next LAK 40,000,000 (LAK 25,000,001–65,000,000)
• 25% — on monthly income above LAK 65,000,000

These brackets mean that a taxpayer earning LAK 5,000,000/month pays approximately LAK 185,000 in PIT — an effective rate of ~3.7%. A taxpayer earning LAK 20,000,000/month pays approximately LAK 1,935,000 — an effective rate of ~9.7%. Annual equivalents are obtained by multiplying monthly thresholds by 12.

Personal Allowances

Taxpayers may claim a personal allowance of LAK 5,000,000 per dependent child, up to a maximum of 3 dependents. This allowance is available to resident individuals supporting dependent children. Eligible dependents include biological children, adopted children, and stepchildren who are under 18, in full-time education, or disabled. Supporting documentation including birth certificates and proof of dependency must be maintained for tax filing purposes.

PIT Withholding

Employers are required to withhold PIT from employee wages each month. The employer calculates monthly tax based on gross salary, applies the progressive bracket rates, and remits the tax to the Tax Department by the 20th of the following month. Employers must register with the Tax Department and file monthly PIT declarations. Failure to remit on time attracts penalties including interest on unpaid tax.

Taxable and Non-Taxable Income

Taxable employment income includes salaries, wages, bonuses, commissions, overtime, allowances, director fees, and other remuneration. Non-taxable items include legitimate business travel expenses, employer contributions to social security, and medical reimbursements. Laos applies a territorial tax system, meaning only income sourced in Laos is subject to Laotian PIT. Foreign-source income of residents is generally not taxed.

Filing Requirements

Employees whose tax is fully withheld at source do not need to file an annual personal tax return. However, individuals with multiple sources of income, self-employment, or business income must file an annual income tax return by 31 March of the following year. Self-employed individuals and sole proprietors are taxed under simplified or actual regimes depending on revenue. Late filing attracts penalties as prescribed under the Tax Law.

FAQs

Do I need to file a tax return if I am a salaried employee?

No, if your employer withholds PIT correctly each month, you are not required to file an annual return. However, if you have additional income from other sources, a return must be filed.

Are bonuses subject to PIT?

Yes, all bonuses, commissions, and additional remuneration are taxable as employment income under the monthly PIT system and are subject to the same progressive rates.

Is there joint filing for married couples?

No, Laos does not allow joint filing. Each individual is taxed separately on their own income.

What currency is used for tax calculations?

Tax is calculated in Lao Kip (LAK). The LAK 1.3M threshold is approximately USD 65 at standard exchange rates. The Tax Department may provide official exchange rates for foreign currency conversions.
