A W-2 from the US is not a Vietnam tax holiday

In plain termsW-2 is the US employment payroll form. Personal income tax (PIT) in Vietnam keys off residence, not off how the US employer prints the wage. There is no treaty to split the difference.

Start here — three checks

Vietnam residence still uses days / abode. Day threshold: 183 days. Worldwide if resident: yes.
No DTA caps. no
FEIE is a US limb, not a Vietnam switch. It exists (yes) with a physical-presence test of 330 days.

Payroll form vs tax residence

Setup	What actually runs	If you treat W-2 as a shield
US company, W-2, you live in Vietnam most of the year	Vietnam residence can open worldwide PIT on that pay.	You file only the US return and ignore Vietnam.
Same job, under 183 days and no Vietnam abode	You may stay a Vietnam non-resident — still test abode, not only the W-2.	A rented flat plus a “visit” story still looks like abode.
You claim FEIE on Form 2555	US exclusion path. Vietnam PIT is a different statute.	You subtract FEIE from a Vietnam return that does not use it.
You hope a treaty credits the other side	No in-force US–Vietnam DTA. Credit/exclusion is domestic, not treaty caps.	You quote a treaty article that is not in force.

Common wrong movesForm type is not residency.

Calling W-2 “US-source only” while you keep a Vietnam home.
Using 330 FEIE days as if they were Vietnam’s 183-day test.
Copying an Australia overlay — Australia has a DTA; the US pair does not.

If you are already over the day countTreat worldwide income as the working assumption.

Open the US–Vietnam tax overlay for FBAR / Form 8938 traps — this page is the W-2 limb.
Do not invent a treaty credit.
A Vietnam work permit is still a separate labour question if you also serve Vietnam clients.

Common questions

If my US employer keeps me on W-2, does Vietnam ignore the salary?

No. Once you are a Vietnam tax resident, worldwide income includes foreign employment pay. A W-2 is the US payroll form. It is not a Vietnam exemption.

Does the US–Vietnam tax treaty cap withholding?

No in-force double tax agreement applies. There are no treaty withholding caps between the US and Vietnam on this overlay.

Can FEIE replace Vietnam PIT?

Foreign earned income exclusion is a US Form 2555 path. The physical-presence limb is 330 full days abroad in a 12-month window. It does not switch off Vietnam residence tax.
