Does renting an apartment for six months make me a Vietnamese tax resident?

This is the residency trigger almost nobody in Da Nang or Ho Chi Minh City has heard of. Vietnam's personal income tax rules treat a long lease as proof of a permanent home, and a permanent home makes you a resident regardless of your day count.

What the rule says

An individual is a tax resident of Vietnam if they meet any of three tests: presence of 183 days or more (calendar year or any 12 consecutive months), holding a temporary or permanent residence card, or leasing a house in Vietnam under a contract with a term of 183 days or more. The lease test is aimed at people who keep a home here while travelling, which describes many remote workers precisely.

What "six months" means in days

Six months is not a fixed number of days. February to July is 181 days; July to December is 184. Landlords in Vietnam usually write leases in months, so read the start and end dates and count. Twelve month contracts, which get the best rents, are 365 days and clearly over the threshold. Serviced apartments booked month by month with no fixed term, and hotel or Airbnb stays, do not count as a lease.

Does it matter if you never stay 183 days?

The test is written so that it does. A nomad who signs a one year lease in An Thuong, spends four months in it and four months in Thailand and Portugal, is a Vietnamese tax resident under the wording of the rule. Residents are taxed on worldwide employment income at progressive rates of 5 to 35 percent, need a tax code and file an annual finalization by 30 April.

Two things soften this in practice. First, if you are also resident in a treaty country, the double tax agreement's tie-breaker rules (permanent home, centre of vital interests, habitual abode) decide which country wins, and Vietnam has agreements with more than 80 countries. Second, the tax office rarely learns about a foreigner's lease unless it is registered for a residence card or a bank file, though banks now report more than they used to.

What to do

If you want a long lease for the price and stability, decide first whether you accept Vietnamese residency for that year. If not, keep contracts under 183 days, or take a rolling monthly arrangement.
