Tax Checklist for Tax Code Closure and Enterprise Dissolution: Settlement, Files, and 6 Common Mistakes
Dissolving an enterprise while "forgetting" tax obligations is the shortest path to a file frozen for years: no tax code closure means no dissolution, and late-payment interest grows the longer you wait. This article systematizes every tax obligation to complete before code closure and dissolution, under the 2025 Law on Tax Administration and the latest tax registration guidance.

1. Code closure vs dissolution: two procedures, one condition
Many owners confuse "tax code closure" with "company dissolution." In fact:
- Tax code deactivation is a tax procedure at the tax authority: the enterprise finalizes all tax obligations and is confirmed debt-free.
- Enterprise dissolution is a business-registration procedure at the registration authority: terminating the legal entity's existence.
The two are linked: the dissolution file is approved only after tax obligations are complete and the code deactivated. The prerequisite for both: no outstanding tax debts, late-payment interest, or penalties.
2. New framework: 2025 Law on Tax Administration and Circular 38/2026
From 1/7/2026, the 2025 Law on Tax Administration (No. 108/2025/QH15) replaced the 2019 Law, comprehensively governing tax registration, declaration, finalization, inspection, and tax code deactivation. Then Circular 38/2026/TT-BTC (effective 18/8/2026) detailed tax registration, including code-deactivation procedures.
Key point: all code-closure files now follow the new framework; in-progress files need transitional-rule checks.
3. Pre-closure tax checklist
- [ ] VAT: file through the final tax period; handle remaining creditable VAT or request refunds (if eligible).
- [ ] CIT: finalize CIT through cessation; correctly determine taxable income from asset liquidation and debt recovery.
- [ ] PIT: finalize PIT for employees through termination; withholding at source for payments to non-residents and foreign contractors.
- [ ] Foreign contractor tax (FCT): review all contracts with foreign contractors still in effect or paid but under-declared.
- [ ] Other payables: business license tax (through cessation), land rent, fees, and charges outstanding.
- [ ] Late-payment interest and penalties: clear all late-payment interest (0.03%/day under the 2025 Law on Tax Administration) and tax administrative penalties.
- [ ] Invoices: report invoice usage through cessation; cancel remaining invoices as required.
- [ ] Refunds (if any): process overpaid or eligible refunds before code closure — refunds after deactivation are far more complicated.
4. Two closure tracks: linked and direct
Current practice has two tracks:
- Linked track: the enterprise files dissolution at the business registration authority; information flows to the tax authority for settlement and code closure. Suits enterprises with "clean" files.
- Direct track: the enterprise works directly with the tax authority to settle and deactivate first, then files dissolution. Suits enterprises with complex tax histories needing extensive explanations.
Track choice depends on current tax-authority guidance and the specific file — check the authentic Circular 38/2026/TT-BTC before deciding.
5. Files to prepare
The deactivation file typically includes: the deactivation request; the owner's/Board's/Members' Council's dissolution decision; asset liquidation minutes; creditor lists and debt-settlement plans; tax finalization files through cessation; invoice-usage reports. Each tax authority may request additional explanations per file specifics.
6. Six common mistakes
- Ceasing operations without procedures: "dormant" companies filing nothing for years → imposed tax, late-payment penalties, and no fast dissolution when needed.
- Missing contractor tax: paid foreign-counterparty contracts without FCT withholding — the most common dissolution-settlement error.
- Skipping employee PIT finalization: withholding and proxy-finalization duties survive through cessation.
- Forgetting invoice cancellation: uncancelled invoices block the tax authority's completion confirmation.
- Small debts freezing files: even a few million VND in late-payment interest can block code closure.
- Losing source documents: missing invoices and originals multiply explanation time with the tax authority.
The two-track TIN closure trap. Vietnam's 2026 framework effectively runs two tracks for TIN deactivation — interlinked and direct — with different steps, timelines, and document sets (notably the 17-18-28/TB-DKT form family). Companies that start on the wrong track discover it months in, when the file is returned and the clock restarts. Before filing anything, confirm with the managing tax authority which track applies to the company's situation (dissolution, merger, conversion, relocation) and obtain the current form checklist — forms and guidance have been updated repeatedly through 2026.
7. FAQs
Q: Are tax code closure and enterprise dissolution the same thing?
A: No. Tax code closure is a tax procedure (deactivating the tax code at the tax authority); dissolution is a business-registration procedure (terminating the legal entity at the business registration authority). They are linked: the enterprise must complete tax obligations and be confirmed by the tax authority before the registration authority approves dissolution.
Q: Which taxes must be finalized before tax code closure?
A: All incurred taxes: VAT (filed through the final tax period), CIT (finalized through cessation), PIT (finalized for employees and withholding at source), foreign contractor tax (if any), plus fees, charges, and outstanding land rent. The tax authority reviews declarations and payments for the entire operating period.
Q: How do linked vs direct tax code closure differ?
A: Linked: the enterprise files dissolution at the business registration authority, and information flows to the tax authority for settlement and code closure. Direct: the enterprise works directly with the tax authority to settle and close the code first, then files dissolution. The choice depends on current guidance and the enterprise's file status.
Q: Can an enterprise with tax debts dissolve?
A: No. Dissolution requires full payment of all tax debts, late-payment interest, and tax administrative penalties — a mandatory condition in the dissolution file.
8. When to work with a lawyer
Work with a lawyer when: the enterprise has a complex tax history (years without finalization, foreign-contractor dealings) and needs an obligation review before code closure; the closure file is stalled or repeatedly queried; or the linked-vs-direct choice needs optimizing for time.
