Key takeaways
- Under the amended Income Tax Law No. 88/NA of 25 June 2025, an individual is a Lao tax resident if they have a permanent residence in Laos or live, earn a living or conduct business there; the law sets no formal day-count test.
- Foreigners who stay in Laos for more than 183 days in any one-year period and receive remuneration from abroad are expected to pay Lao personal income tax on it, at progressive rates from 0% to 25%.
- Laos grants no unilateral credit for foreign tax and has only 11 double tax treaties, so the location of your income and your treaty position matter as much as the residence itself.

Who is a tax resident in Laos?
Lao residence rules are set by the amended Income Tax Law No. 88/NA of 25 June 2025, Article 3 (items 11 and 12). It distinguishes two categories:
- Resident: a person who has a permanent residence in Lao PDR, or who lives, earns a living or conducts business in Lao PDR.
- Non-resident: a person who comes to Lao PDR to earn a living or conduct business but has no residence, permanent address or permanent place of business there.
Two consequences follow. First, residence in Laos is a facts-and-circumstances test, not a pure day count: a foreigner who rents a home in Vientiane and works there is resident from the start of the stay. Second, the frequently quoted "183 days" is not the definition of residence. It is the threshold at which foreigners who receive remuneration from a foreign country are expected to pay Lao personal income tax on that pay.
Expatriates who work in Laos and are paid there owe Lao personal income tax regardless of how long they stay. In other words, the day count only decides whether foreign-paid income is pulled into the Lao net.
What about companies?
Lao tax and VAT law do not define corporate residence or permanent establishment. Lao-registered enterprises are taxed on their profits, and foreign suppliers without a Lao registration are taxed through a final foreign withholding tax collected by their Lao customers. Double tax treaties apply the usual "fixed place of business" definition of a permanent establishment.
How do you obtain tax residency in Laos step by step?
Laos has no dedicated residence-by-investment or digital nomad tax programme. Tax residency is the by-product of living and working there legally. The usual path for a foreign professional is:
- Enter on a long-stay visa. Long stays usually require a business, investment or labour category visa rather than a tourist visa, sponsored by an employer or by your own registered Lao company.
- Obtain a work permit and stay permit. Your sponsor applies to the labour authorities (Ministry of Labour and Social Welfare) for the work permit and to the immigration authorities for the stay permit, typically with your passport, visa, employment contract and medical certificate.
- Register your address. Foreign residents must register their place of stay with the local authorities (village office or police). Keep the registration, your lease and utility bills; they are your best evidence of a "permanent residence" in Laos.
- Get a Tax Identification Number (TIN). Individuals must obtain a TIN. Employees are usually registered through their employer.
- Pay tax through payroll or self-assessment. Employers withhold personal income tax monthly and remit it by the 20th of the following month. Individuals file an annual return for the prior year by 31 March.
- Keep a residence file. Track entry and exit dates, especially if you are also paid from abroad, since crossing 183 days in a one-year period changes the treatment of that income.
How much tax do Lao residents pay?
Lao personal income tax applies the same progressive scale to Lao nationals and foreigners.
| Annual taxable income (LAK) | Rate |
|---|---|
| 0 – 30,000,000 | 0% |
| 30,000,001 – 60,000,000 | 5% |
| 60,000,001 – 180,000,000 | 10% |
| 180,000,001 – 300,000,000 | 15% |
| 300,000,001 – 780,000,000 | 20% |
| Above 780,000,000 | 25% |
Other rates to know: dividends and partnership profit shares bear 10% withholding tax, interest on loans from non-bank sources 10%, and bank deposit interest is exempt. Sole traders and independent contractors are taxed under the business profit-tax rules (standard rate 20%) rather than the salary scale. Late filing or payment costs 0.1% per day of the tax due.
Example. A foreign project manager employed by a Lao company on LAK 400 million a year pays nothing on the first LAK 30 million, then 5%, 10% and 15% on the next bands and 20% on the slice above LAK 300 million, for roughly LAK 51.5 million in total (an effective rate of about 13%), withheld monthly by the employer.
What does Lao residency mean for location-independent professionals?
Laos can look attractive on headline rates, but remote workers should weigh three structural points:
- Foreign-paid income is in scope after 183 days. A remote employee or contractor paid by a foreign company who stays more than 183 days in a one-year period is expected to pay Lao personal income tax on that remuneration.
- No unilateral foreign tax credit. Laos does not credit foreign tax paid on foreign income. Relief only exists where a treaty provides it, so a remote worker from a non-treaty country (for example the US, the UK, France or Germany) risks paying tax twice.
- Permanent-establishment risk for your employer or company. Working from Laos for a foreign company can create a taxable presence for that company under treaty rules, or trigger foreign withholding tax when Lao clients pay you. Check this before relocating.
Laos also does not offer a digital nomad visa, so working remotely on a tourist visa is not a compliant basis for a long stay.
How do tax treaties change Lao residency?
Laos has double tax treaties with Brunei, China, Indonesia, Luxembourg, Malaysia, Myanmar, North Korea, Russia, Singapore, Thailand and Vietnam. If you are resident in both Laos and one of these countries under their domestic laws, the treaty tie-breaker decides where you are resident for treaty purposes, usually in this order: permanent home available to you, centre of vital interests, habitual abode, then nationality.
For example, a Thai national who keeps a family home in Bangkok but works in Vientiane during the week may be resident in both countries domestically; under the Laos–Thailand treaty, the permanent home and centre of vital interests tests would decide. The tie-breaker only applies once both countries claim you as resident under their domestic law.
To claim treaty benefits abroad, you will usually need a certificate of tax residence from the Lao Tax Department (Ministry of Finance).
Frequently asked questions
How do you become a tax resident in Laos?
Under the amended Income Tax Law No. 88/NA (2025), you are a Lao tax resident if you have a permanent residence in Laos or live, earn a living or conduct business there. In practice, foreigners become resident by moving to Laos on a long-stay visa with a work permit and stay permit, registering their address, obtaining a tax identification number and paying personal income tax through payroll or an annual return.
Is there a 183-day rule for tax residency in Laos?
Not as a formal residence test. Lao law defines residence by permanent residence or by living and working in the country, not by a day count. The 183-day figure matters for foreign-paid income: foreigners who stay in Laos for more than 183 days in any one-year period and receive remuneration from abroad are expected to pay Lao personal income tax on it. Treaties may also use a 183-day test for employment income.
What is the income tax rate for residents in Laos?
Lao personal income tax is progressive from 0% to 25%. On an annual basis, the first LAK 30 million is taxed at 0%, then 5%, 10%, 15% and 20% bands apply, and income above LAK 780 million is taxed at 25%. The same scale applies to Lao nationals and foreigners. Employers withhold it monthly, and individuals with other income file an annual return by 31 March.
Does Laos tax foreign income?
Laos taxes income earned in Laos regardless of residence, and foreigners present for more than 183 days in a one-year period are expected to pay tax on remuneration received from abroad. Laos does not grant a unilateral credit for foreign tax on foreign income, so double taxation is only relieved where a treaty applies. Treatment of passive foreign income such as foreign dividends is not clearly codified.
Which countries have a tax treaty with Laos?
Laos has double tax treaties with 11 jurisdictions: Brunei, China, Indonesia, Luxembourg, Malaysia, Myanmar, North Korea, Russia, Singapore, Thailand and Vietnam. These treaties contain tie-breaker rules for dual residents, typically based on permanent home, centre of vital interests, habitual abode and nationality, and they reduce withholding taxes on dividends, interest and royalties.
Can I get a tax residence certificate in Laos?
A certificate of tax residence is normally requested from the Lao Tax Department under the Ministry of Finance to claim treaty benefits abroad. You will need a tax identification number and evidence that you file and pay tax in Laos. The exact form, fee and processing time are not published in an official English source.
