How do you get a personal tax code in Vietnam in 2026?

A foreign individual with income subject to Vietnamese personal income tax needs tax registration. The common route is employer-led: you authorise the company paying the income, provide a valid passport copy and required personal details, and payroll includes you in its consolidated electronic registration. Confirm the passport number and name order before submission because Vietnam's database matches foreign taxpayers through passport information.

If you must register directly, use the individual tax-registration form and file with the tax authority responsible under Circular 86/2024. The current authority is the tax administration under the Ministry of Finance. Use the official Electronic Tax portal, commonly called eTax, or the current public-service channel named by the managing tax office. Do not follow an old guide to an abolished district-level office after the 2025 administrative reorganisation.

Prepare your passport, contact and address information, employment or income details, and the form for the selected route. An employer may also request an authorisation document so it can register for you. Keep the electronic receipt and resulting code, then search the official tax system using the same passport details.

Payroll uses the code when reporting salary, tax withheld, and dependent deductions. At year end, the employer may complete personal income tax finalisation for an authorised employee, or you may need to file directly when income sources or departure circumstances require it. Finalisation means reconciling the tax withheld during the period with the amount due.

The code does not make you a Vietnamese tax resident. Tax residence follows the Personal Income Tax Law's presence and home tests, tax-treaty rules where applicable, and your facts. A non-resident can still have Vietnam-source income and a tax code. Give payroll accurate arrival, departure, accommodation, and overseas tax-residence information instead of treating the code as the answer.

Do not ask a new employer to create another code. Give it the existing number and matching passport history. Duplicate codes often arise from different name order, accents, spacing, or an old and new passport. Ask the managing tax authority or payroll team to correct and merge the records using the current amendment procedure under Circular 86/2024.

VNeID is Vietnam's electronic identity system. From July 2025, Vietnamese citizens use their personal identification number for tax procedures, but a foreigner's passport remains the key identity document for foreign-person registration. Do not enter a borrowed VNeID account to force an online application.

Before leaving Vietnam, ask payroll which final return, authorisation, tax payment, or refund step applies and obtain withholding records. Update the tax file after a passport, address, or tax-residence change. The tax code remains an administrative identifier and creates no visa, work-permit, or residence-card right.
