You get to the counter at Tan Son Nhat, passport and boarding pass in hand, and the officer tells you to step aside. No fine. No form to fill in. Just a note on the screen that says you cannot leave Vietnam today.
That is a temporary exit suspension under Decree 252/2026/ND-CP, and since 1 July 2026 it applies to foreign nationals with overdue tax liabilities. The tax office that manages you can send a notice straight to the immigration authority, and your name lands on the system that airport and land border officers check when you try to depart.
Three different things get mixed together here, so it is worth separating them early:
For anyone living in Saigon on back-to-back visas, the practical questions are narrower: what the thresholds are, who actually gets flagged, how to check your own tax record before you book anything, and how quickly a suspension comes off once the debt is paid.
Vietnam has been blocking exits over tax debt for years, and the scale is not small. As of May 2025 the tax department had issued roughly 61,500 temporary exit suspension notices covering about 83 trillion VND in unpaid tax, and 36,646 of those taxpayers had abandoned their registered business address.
The mechanism itself was already in law. Decree 49/2025/ND-CP set the VND thresholds in February 2025. Decree 252/2026/ND-CP, signed 30 June 2026 and effective 1 July 2026, is the detail decree that fills in how it is applied.
Article 28 of the decree lists the cases. These are the ones that reach foreigners in Vietnam:
| Who | Trigger | Notice step |
|---|---|---|
| Business individuals and household business owners | Debt of 50 million VND or more, overdue 120 days or more, and subject to enforcement of a tax administration decision | 30-day warning, published online |
| Legal representatives and beneficial owners of enterprises, cooperatives and cooperative unions | Company debt of 500 million VND or more, overdue 120 days or more | 30-day warning, published online |
| Anyone whose business has stopped operating at its registered address | 120 days after the tax office issued the inactive-at-address notice with no tax code restored or closed | 30-day warning, published online |
| Foreign nationals with overdue unpaid tax | Any overdue tax liability not yet settled, with no minimum amount written into the decree | No warning period. Notice to the immigration authority is immediate |
Read the bottom row again, because it is the one that catches people who have never run a company in Vietnam. For a foreign national the decree says the case is simply having tax owed past its deadline and not paid. There is no 50 million floor and no 120-day waiting period mentioned for that category, and there is no 30-day notice before the immigration authority is told.
Who this realistically means: a foreigner who filed a personal income tax return and left a balance unpaid, someone who took local employment and had a finalisation shortfall, a freelancer or contractor with a Vietnamese tax code, and the quieter one, a foreigner who agreed to be the legal representative or a 25%-plus owner of a Vietnamese company that then fell behind.
The suspension does not arrive as a letter you can argue with at a counter. It arrives as a line in the immigration database. When you present your passport at Moc Bai, at Tan Son Nhat, or at any other departure point, the officer sees the flag and the exit is refused.
This is the part that frustrates people most: there is nothing to pay at the border. An overstay fine can be settled on the spot and you carry on. A tax exit suspension cannot. The officer has no mechanism to take the money, and no authority to clear the flag. Only the tax authority that issued the notice can lift it, and it lifts it through the system.
Two practical consequences follow from that.
The stacking problem. A blocked exit does not pause your visa. Your permitted stay keeps ticking while you are stuck, which means an exit suspension over a tax debt can turn into an overstay fine under Decree 282/2025 and, past day 16, into a deportation case under Decree 59/2026. Two separate files, one cause.
The flip side is worth saying too: the decree's whole design is to make paying easier, not to trap people. The tax office has to notify you, has to publish the notice, must lift the measure as soon as you qualify, and must tell you 30 days before an extension. If you never received anything and never had a tax code, ask the tax office directly rather than assuming the worst.
Tax officials have been telling people the same thing since the decree took effect: look at your own record before you travel. You do not need an agent for the first step.
Every registered taxpayer can log into the electronic tax portal at thuedientu.gdt.gov.vn and see tax settlements, outstanding debt, notices sent to the account, and any suspension notice. The same information sits in the eTax Mobile app, which added exit suspension lookups to the tax debt view and can be opened with fingerprint or Face ID instead of typing a password.
Suspension notices are published on the tax authority's website at the same time they are sent, so the lists are public. Pasting a name into a public PDF is not a reliable way to clear yourself though, since Vietnamese names repeat and company notices carry the company name rather than yours. Two better routes:
Then you are usually outside the scope of all four categories, because every one of them assumes a tax debt registered against a taxpayer in the system. Being outside the scope is not a permanent state. Move from a tourist visa to local employment or a business role and you acquire a tax code, and with it the possibility of a debt.
Everything here runs through the tax authority that manages your file. Nobody at the border can help, and paying a broker is not a shortcut.
Once the tax office confirms your obligation is complete, the lift notice goes to the immigration authority electronically. Under Decree 252 that happens as soon as the conditions are met, not within a working day. The immigration side then updates its system, which is the part that decides whether you actually board.
This was a real complaint before the decree: money paid, flag still up. Decree 252 added a route for it. You can submit electronic evidence of payment through the tax administration system, the tax office verifies it, updates the record, and issues the lift notice. Keep the bank transfer confirmation, the receipt number and the date. Do not throw them away because the portal still looks wrong.
For the enforcement cases, the suspension can now come off without you clearing the whole debt. If the remaining balance drops below 50 million VND for an individual or household business, or 500 million VND for an enterprise, cooperative or cooperative union, the measure can be lifted. This is new: under the old rule you generally had to settle the lot.
If you are caught because a business stopped operating at its registered address, the exit restriction can come off when you restore the tax identification number, complete the filings, cut the debt below the threshold, or finish closing the tax code properly. Doing nothing keeps it in place.
If the debt is still unpaid as the suspension period runs out, the tax office has to notify the immigration authority, your electronic tax account and its own website at least 30 days before the extension. For foreign nationals this was the first time the extension process was spelled out. An exit suspension for a foreign national can run up to three years under the entry and exit law, so a debt nobody deals with does not quietly expire.
A Moc Bai visa run is a departure. You exit Vietnam at the land border, step into Bavet, walk back through, and enter on the new e-visa. The whole plan depends on being allowed out.
An exit suspension breaks that at the first step. There is no version of the run where you pay the tax debt at the border desk, and there is no way for a visa run service to move a flag that only a tax office can clear. If you are already blocked, the honest sequence is: sort the tax file first, then run.
Three patterns worth knowing about, because they are how foreigners get into this without meaning to:
If you have no tax code and no company connection, this page is background reading. If you have either, check before your visa is down to its last week. The cost of checking is nothing, and the cost of not checking is a missed flight plus an overstay clock you cannot stop.
Most Saigon problems start with a date nobody wrote down. If your e-visa is inside its last two weeks, a same-day run from Ho Chi Minh City to Moc Bai resets the clock legally, with the transport, the Cambodia entry and the new Vietnam e-visa handled for you.
