Scenario: an investment fund signs an agreement to acquire 70% of a factory project inside an industrial park. Three months after closing, the tax authority issues a retroactive land-rent collection for two years plus late-payment interest because the project had enjoyed a land-rent exemption with no determination decision behind it. The amount appeared in none of the seller’s financial reports. Reviewing land financial obligations is the most under-weighted part of project M&A due diligence in Vietnam — because land debts rarely show up fully in accounting books. This article builds the buyer’s complete checklist.
The map of a project’s land financial obligations
An operating project accumulates six layers of land-linked obligations. Layer one is State land rent (for direct State leases) or sub-lease rent to the park developer (for in-park projects): the check is not only “which periods are unpaid” but the project’s position in the 5-year unit-price stability cycle under clause 2, Article 153 of the Land Law 31/2024/QH15 — a project about to enter a new pricing cycle carries a very different cost profile from one that has just entered. Layer two is land use fees for projects allocated land with a fee: outstanding principal and the instalment schedule in the allocation decision. Layer three, the most dangerous because invisible, is incentives already enjoyed: every land-rent exemption or reduction the project enjoys must rest on a determination decision under Article 48 of Decree 103/2024/ND-CP and still meet its conditions (sector, area, basic-construction timeline) — incentives enjoyed wrongly or without confirmation are retroactively collected on audit, with late-payment interest of 0.03%/day under clause 2, Article 16 of the Law on Tax Administration 108/2025/QH15 running over the wrongly enjoyed period. Layer four is the annual non-agricultural land use tax, a small tax but the most frequently forgotten. Layer five is operating debts to the park developer: service charges, wastewater fees, unsettled utilities. Layer six is completion items: registration fees and change registrations for the project’s earlier asset transfers and entity changes — an old transaction never properly registered will jam every land procedure of the buyer.
Verification method: three independent sources for every figure
The due-diligence principle is that no obligation is confirmed by documents the seller prepared itself. For tax and land rent: require the tax authority’s payment notices for recent periods with treasury receipts, plus a tax-obligation status confirmation issued by the tax authority for the seller — it lists arrears per the tax management system and is the strongest evidence obtainable before closing. For incentives: cross-check the exemption/reduction determination decision against the real project file (does the sector on the Investment Registration Certificate still match actual operations; did actual basic construction exceed the 3-year cap). For park debts: the developer’s written debt confirmation near closing, because only the developer knows exactly how much service charge the seller still owes. And one cheap background check: search for tax enforcement status, project mortgages and land disputes of the project entity — a project under tax enforcement is a sign the obligation map has more layers yet to surface.
Buyer protection structures in the M&A contract
Review findings must be converted into four mechanisms in the purchase agreement. First, a disclosure schedule: every land debt and obligation of the project listed by the seller as an annex — anything not listed that arises from before closing is by default the seller’s risk. Second, a price holdback or third-party escrow, released in stages: part after the transaction’s tax settlement confirmation, the rest after a period long enough for a tax audit to surface retroactive collections — the holdback size is quantified from the review itself (unconfirmed incentives are the largest reserve item). Third, land-specific conditions precedent: confirmation of no land-rent/tax arrears, the park developer’s debt confirmation and (where applicable) a valid incentive determination decision are conditions for closing to occur. Fourth, land-specific representations and indemnities with a survival period longer than ordinary commercial warranties, because land retroactive collections typically surface only on audits years after closing. All four mechanisms are cheaper than any lawsuit — and they can only be negotiated when the buyer ran the review checklist before signing the term sheet.
Frequently Asked Questions
What land financial obligations must be reviewed when acquiring a project?
Six obligation groups must be reviewed before closing: (1) State land rent — whether all periods are paid, and which year of the 5-year unit-price stability cycle the project is in under clause 2, Article 153 of the Land Law 31/2024/QH15 (an imminent price reset is a valuation risk); (2) outstanding land use fees if the project was allocated land with a fee (principal and the payment schedule in the allocation decision); (3) exemptions and reductions already enjoyed — whether a determination decision exists under Article 48 of Decree 103/2024/ND-CP and conditions are still met (wrongly enjoyed incentives are retroactively collected on audit); (4) annual non-agricultural land use tax; (5) sub-lease rent and service charges owed to the park developer; (6) hidden items: late-payment interest, administrative fines on land/tax, and registration fees plus change registrations left incomplete for the project’s earlier land transactions.
How can the buyer know how much land rent and land tax the seller still owes?
Verify through three independent channels, never the seller’s word: (1) require the seller to produce all land-rent payment notices and treasury payment receipts for recent periods, plus a tax-obligation status confirmation reconciled with the tax authority (the standard due-diligence document); (2) rebuild the figures from the root land file — the land lease decision, exemption/reduction determination decisions, unit-price notices per cycle — recompute what should have been paid and compare with what was paid; (3) for amounts owed to the park developer, require the developer’s own written debt confirmation close to closing. A channel that refuses to produce documents is itself a due-diligence finding: price the deal with a corresponding reserve instead of assuming zero.
Does the seller’s land-rent debt transfer to the buyer?
Separate it by obligation subject. State land-rent debt attaches to the land user named in the land lease decision: in tax principle the seller remains the taxpayer for pre-transfer periods and the tax authority collects from the seller; but practical risk still reaches the buyer through three paths: the tax authority applies enforcement measures against the asset/project while the debt is unresolved; the buyer’s own change-registration and project-transfer procedures stall until outstanding obligations are clarified; and sub-lease rent and charges owed to the park developer are contract obligations that travel with the sub-lease position the buyer inherits when taking over the project. The practical answer is: the debt does not automatically change owner, but it must never be left outside the purchase agreement.
If debt surfaces after the purchase, how does the buyer claim it back from the seller?
Recovery depends entirely on what was locked before closing, in order of strength: (1) a holdback/escrow — part of the price held in a blocked account pending settlement, with discovered debt set off directly, no lawsuit needed; (2) representations and indemnity — the seller warrants no land financial debts beyond the disclosed list and indemnifies all retroactive collections arising from pre-closing periods, with a survival period long enough to cover the tax-audit cycle; (3) conditions precedent — tax-clearance confirmation and the developer’s debt confirmation are conditions to closing, and if the seller cannot produce them the buyer may postpone or walk away. With none of the three, the buyer is left suing for damages under the Civil Code 91/2015/QH13 — far slower and costlier.
