FAQ – Frequently Asked Questions

Below are the most frequently asked questions about personal income tax finalization for foreigners, with detailed answers:

Do foreigners working less than 183 days need to file tax returns?

Non-resident foreigners (working less than 183 days) are only required to file PIT returns in cases of: mid-year termination, permanent departure, or having income from 2+ organizations during the year. If only working for one organization and not falling into the above special cases, non-residents have no mandatory finalization obligation.

However, in many cases, voluntary finalization may be beneficial if tax was overpaid and there’s opportunity for refunds. You should consider calculating to assess whether finalization should be done.

What needs to be done when leaving Vietnam mid-year to complete tax procedures?

Foreigners leaving Vietnam permanently must complete full PIT finalization procedures before departure and receive a certificate of completed tax obligations from competent authorities. The specific process includes: submit finalization documents → wait for tax authority processing → complete financial obligations (additional payment or receive refunds) → receive certificate → permitted to depart.

The implementation deadline is before the expected departure date or within the prescribed time after having a decision to return home. Failure to complete these procedures may result in being stopped at departure checkpoints.

Collect accurate documents from all workplaces, don’t miss any
Calculate tax based on total income according to progressive tax rates, not separately for each source
May need additional payment due to higher tax rates applied to total income
Deadline is 90 days after the end of tax year according to regulations
