How many days can you stay in Vietnam before becoming a tax resident (and why visa runs might get restricted)?

One nuance raised: if you're in the country on an e-visa (tourist status), those days reportedly don't count toward tax residency — the threshold should be calculated from around 6 months of stay.

The key threshold is 183 days in-country per year — that's when Vietnamese tax residency kicks in.

There's speculation authorities will introduce a 90-day-per-6-months limit for people constantly doing visa runs, closing the loophole that lets long-term residents avoid tax residency.

For those planning to live in Vietnam long-term, the advice is to get a work permit and pay taxes legally instead of relying on endless visa runs.
