Does Vietnam actually enforce the 183-day tax residency rule for foreigners staying on a tourist visa without a work permit?

Counter-argument raised in the thread: tax residency does not depend on visa type (including tourist visas). Living for years without paying is a personal risk, not proof there's no obligation. Many people live in a gray zone for years — even running businesses — without paying taxes, including in their home country, but that doesn't mean no taxes are owed.

Even if tax authorities got interested, proving remote work income is very hard: if salary comes to a foreign (non-Vietnamese) bank account, there's no local transaction history to serve as evidence.

If proving tax residency were ever required, the reported list of documents includes: all visa stamps in the passport, a rental/lease agreement, salary statements and an employment contract — plus an explanation for why no work permit exists despite paying taxes.

One workaround people mention: explaining the source of funds as proceeds from selling property back home rather than as income — this way there's technically nothing taxable in Vietnam.

Expats believe there's no unified database linking immigration and tax authorities in Vietnam — similar to how in Turkey, even border control and the migration office don't share one database (cited as a comparable example).

The consensus in the discussion: due to a legal contradiction (no work permit but there is income), nobody really knows how to apply the 183-day rule to such foreigners in practice — it remains a gray area.
