Scenario: an FDI factory wants to exit an industrial park and assign its remaining 18-year land sub-lease position to another manufacturer. Both sides assume the deal is theirs alone — until the park developer declares the sub-lease “does not permit assignment” and demands renegotiation from scratch. Assigning a land sub-lease is a three-party transaction by nature. This article analyses its conditions, procedure and taxes.
Three transactions that are easily confused
Sub-lease assignment: the object is the tenant’s position under the land sub-lease with the developer — the typical route for annual-payment sub-leases, where the tenant holds no land use rights certificate. Land use right transfer: applies where the sub-lessee paid lump-sum and was certified under Article 202 of the Land Law 31/2024/QH15; this is a land-rights transaction executed through registration at the land registration authority, without needing the developer’s “permission” in the contract-assignment sense (though the sub-lease may carry a notice clause). Investment project transfer: where the buyer acquires the whole project (leased land, factory, operations), the deal also follows project-transfer procedure under the Law on Investment 143/2025/QH15, including assignee conditions and amendment of the Investment Registration Certificate. Choosing the wrong transaction character leads to wrong procedure, wrong tax and a contract the developer may refuse to recognise.
Assignment procedure: the developer’s central role
Contract assignment in Vietnamese civil law requires the remaining party’s consent, because their rights and obligations attach to a specific counterparty. In park practice, the assignment dossier comprises: the assignor’s request with a draft tripartite agreement; the assignee’s capability and sector file for the developer to check against the zoning plan and park conditions; confirmation of the assignor’s financial standing (sub-lease rent, infrastructure fees, utilities) to the transfer date; and the agreed split of prepaid rent, security deposits (transferred to the assignee or refunded to the assignor) and responsibility for assets attached to land. The transfer’s effective moment should be the date the developer signs the tripartite confirmation and the assignee completes its investment procedures — not the date the two trading parties privately agree — avoiding the gap where “the buyer has paid but is not yet the lawful tenant”.
Tax, valuation and the classic reassessment traps
For corporate income tax, assignment income is determined separately under the real-estate transfer framework of the Law on Corporate Income Tax 67/2025/QH15 and Decree 320/2025/ND-CP: revenue at the actual transfer price (but not below the tax authority’s determined base where the declared price is off-market), less the cost basis of the lease right/assets and valid transfer expenses. Two classic reassessment traps: low pricing in related-party deals — the tax authority applies market pricing under Decree 255/2026/ND-CP on transfer pricing; and “forgetting” to declare the value of assets attached to land travelling with the contract. On the assignee’s side, registration fees under Decree 10/2022/ND-CP may arise where certified assets are received. The assignment agreement needs a complete tax clause: the assignor bears income tax on the transfer and any arrears from under-declaration; the assignee bears only its own fees; both cooperate on documents when the tax authority calls. After closing, the assignee should keep the full file (tripartite agreement, developer confirmation, tax receipts) as the foundation for every later transaction on the same plot.
Frequently Asked Questions
What is assignment of an industrial land sub-lease, and how does it differ from transferring land use rights?
Assignment moves the current sub-lessee’s entire rights and obligations under the land sub-lease to a third party, which steps into the tenant position toward the park developer. It differs from a land use right transfer in two ways: the object is a contractual position (plus assets attached to land, if any), not an independently certified land use right — the route used mainly for annual-payment sub-leases, where the tenant holds no land certificate to transfer; and the transaction mandatorily requires the developer’s consent because it substitutes the developer’s counterparty. Where the sub-lease was paid lump-sum and certified, the orthodox route is a land use right transfer through land registration instead.
What conditions and steps does a sub-lease assignment require?
Four core conditions: (1) the current sub-lease does not prohibit assignment, or the developer consents in writing; (2) the assignee meets the park’s conditions (sector fitting the zoning plan, project capability, and — for a foreign investor — the corresponding investment procedures); (3) the assignor has settled obligations up to the transfer date (no arrears of sub-lease rent or infrastructure fees) or the dossier arranges those debts; (4) a tripartite assignment agreement (assignor — assignee — developer) fixing the handover moment for rights, obligations, deposits, prepaid rent and assets attached to land. Afterwards the assignee completes investment procedures (amending or obtaining the Investment Registration Certificate) and registers changes if a land certificate exists.
What taxes and costs arise on assigning a land sub-lease?
The assignor incurs corporate income tax on the assignment gain (transfer revenue less cost basis and valid expenses) — for transactions in the nature of real-estate/rental-right transfers, declaration follows the real-estate transfer income rules of the Law on Corporate Income Tax 67/2025/QH15 and Decree 320/2025/ND-CP, determined separately from production-business income. If certified assets attached to land transfer together, the assignee may owe registration fees under Decree 10/2022/ND-CP plus change-registration fees. The biggest tax risk is below-market pricing between related parties — the tax authority may re-determine value under the transfer-pricing regime (Decree 255/2026/ND-CP). All taxes and fees should be allocated in the assignment agreement, with a clause on who bears reassessment arrears.
How long does the name transfer take, and must a completely new contract be signed?
Timing depends mainly on the park developer’s appraisal speed for the transferee (financial capacity, whether its business lines fit the park’s planning) and the land file’s status — in practice a few weeks to a few months, longest at the developer’s written consent step. On form, a completely new sub-lease is not required: the common route is a tripartite contract-assignment agreement under which the transferee steps into all rights and obligations of the transferor under the existing sub-lease, keeping the price and remaining term unchanged. If the developer insists on a new contract, the transferee must lock conditions no worse than the old one (especially rent and remaining term) and handle change registration and file updates with the Management Board and the land registration authority if the original contract was registered.
