VietnamPAYE in Britain does not freeze Vietnam’s day-count
In plain termsPAYE is Pay As You Earn — UK employer withholding. NI is National Insurance. HMRC is the UK tax authority. None of those is a Vietnam visa, and none of those is the Vietnam 183-day test.
Start here — three checks
- Vietnam still counts days. Threshold 183 days. Worldwide if resident: yes.
- A treaty exists. yes · Art 15 short-stay 183 days.
- Credits, not a leftover figure. UK credits VN tax: yes. Vietnam credits UK tax: yes.
Payslip, short-stay article, and credit limb
| What is running | What it does | If you collapse them |
|---|---|---|
| PAYE and NI on a UK payroll | HMRC withholding. The employment contract is still British. | You treat Real Time Information as a Vietnam clearance. |
| Vietnam days or a Vietnam abode | Residence can tax worldwide income, including UK salary. | You keep a District 1 lease and call yourself a visitor for HMRC only. |
| Article 15 short-stay | Employment-income limb at 183 days — a treaty test, not a visa. | You copy US FEIE logic onto a UK contract (the US has no VN treaty). |
| Article 22 credits | Each side may credit tax paid to the other. Amounts yes. | You ask for a net-of-NI VND leftover this product will not invent. |
Common wrong movesAustralia PAYG and Super are a different payroll form.
- Pasting PAYG or W-2 logic onto a UK PAYE code.
- Reading the UK overlay’s TNR / FIG / State Pension notes as if they computed PAYE.
- Assuming National Insurance “already covered Asia.”
If PAYE is still coming off every paydayKeep the UK withholding. Add the Vietnam residence test.
- Count Vietnam days and test abode.
- Open the UK → Vietnam overlay for dual-residence and pension geography — this page is the payroll form.
- Do not expect modelled leftover after NI.

Common questions
If HMRC keeps taking PAYE, is Vietnam closed?
No. PAYE is UK Pay As You Earn withholding, often with National Insurance. If you become a Vietnam tax resident, worldwide income includes that salary. A UK payslip is not a Vietnam filing.
Does Article 15 let me ignore Vietnam after 183 days here?
Article 15 is the employment-income short-stay limb, filed at 183 days. It is a treaty test, not a Vietnam day-count off-switch. Residence can still open worldwide income.
Can you net PAYE, NI, and Vietnam PIT into one leftover?
No. Article 22 credits exist both ways. The leftover amounts are filed as not modelled. This page will not invent a monthly figure.
