Who files the annual PIT finalization?

In plain termsPersonal income tax (PIT) finalization is not “whoever remembers.” NĐ 253 splits the employer’s payroll duty from the resident’s yearly duty, then lists when you may authorize the company — and when you cannot.

Start here — three checks

Payer always runs payroll finalization. yes
Authorization is narrow. One employment source, contract ≥ 3 months, still working there.
Leaving Vietnam is a hard date. Foreign residents ending work finalize before exit (yes).

Who is the actor?

Situation	Who files	If you guess wrong
Company payroll, you still work there, one labour contract ≥3 months	You may authorize the payer (Điều 51.2).	Silence is not authorization. Ask HR to confirm the mandate.
Second salary source, or you already left that employer	Authorization usually fails. Resident salary still finalizes (yes).	Two payers, nobody owns the year.
You want extra medical/education/charity deductions	Self-file. Authorization closed (yes).	HR files a clean year; your deduction never appears.
Foreign resident, contract ending, airport next month	Finalize or authorize before exit.	Exit with an open PIT year.

Common wrong movesFinalization is not a January rumour.

Assuming “the company always does it” after you already resigned.
Authorizing HR and then claiming hospital bills on the side.
Leaving Vietnam first and treating PIT as a later email.

If HR says they will handle itGet the mandate on paper.

Confirm you still meet the one-source / still-working test.
If you have a second income stream, plan a self-file instead.
If you are exiting, put the pre-exit finalization on the same checklist as the permit return.

Common questions

Does my Vietnam company file my annual PIT finalization for me?

The income-paying organisation must run payroll finalization. A resident employee with salary income also finalizes yearly unless a listed exception applies. You may authorize the company only if you meet Điều 51 khoản 2 (typically one employment source, labour contract ≥3 months, still working there).

When can I not authorize the company?

If you claim disaster/illness tax reduction or extra Điều 49 deductions (medical, education, charity), you must self-file. Authorization is closed.

I am leaving Vietnam. Who files?

A foreign tax resident ending a Vietnam work contract must finalize PIT, or authorize someone, before exit.
