Scenario: the project’s first-year land rent notice comes in 40% above the financial model, and nobody on the project team can point to which component of the formula ran differently from plan. Land rent is a three-component multiplication — area × percentage rate × land price — and the error can sit in any component. This article dissects the formula under Decree 103/2024/ND-CP so the enterprise can verify every land tax notice itself.
The formula’s three components
Under Decree 103/2024/ND-CP on land use fees and land rent, annual land rent payable equals the rentable land area multiplied by the land rent unit price. The unit price is not a ready-made number: it is the product of the percentage rate for unit-rent calculation and the land price for rent calculation. Component one, area: the State-leased area subject to rent (after deducting exempted parts per decision), per the allocation/lease file and survey. Component two, the percentage rate: decided by the provincial People’s Committee for each land type and area within the prescribed framework — and Article 33 of Decree 103/2024/ND-CP sets a default rate of 1% where the locality has not issued a specific rate. Component three, land price: taken from the Land Price List issued by the provincial People’s Committee (Article 159 of the Land Law 31/2024/QH15) for the plot’s position and exact use purpose. Multiplying the three gives the unit rent (VND/m²/year); multiplying by area gives the annual amount.
The five-year stability cycle and how unit prices move between cycles
The system’s most important technical point is clause 2, Article 153 of the Land Law 31/2024/QH15: annual land rent is stabilised within a 5-year cycle from the State’s lease decision. Inside the cycle, even if the price list changes (from 1 January 2026 it is issued annually), the project’s unit price is not recalculated. Into the next cycle, the new unit price is set off the price list of the new cycle’s first year, but its increase over the previous cycle is limited to a Government-set rate for each period and may not exceed the cumulative consumer price index (CPI) of the five years preceding that cycle. For long-term financial modelling, this means the project should not assume the unit price tracks full price-list movements, but model it in 5-year steps with a capped increase. Mid-cycle recalculation occurs on: change of leased area, change of land use purpose, detailed-planning adjustment altering coefficients/purposes, or expiry of the land-rent exemption period moving into full payment.
Applying the formula to two situations enterprises actually meet
Situation one — a project leasing directly from the State: the enterprise is the land rent payer receiving tax notices; all verification runs through the three components above plus exemption/reduction status (basic construction period and incentives under Articles 39 and 40 of Decree 103/2024/ND-CP). Situation two — a factory sub-leasing inside an industrial park: the enterprise pays no State land rent; what it pays is a market sub-lease price to the developer. Yet understanding the State formula still has real negotiating value: it reveals the developer’s root land cost inside the sub-lease price composition, and separates true land cost from infrastructure, management and margin. One calculation error to avoid in both situations is applying commercial-service land prices to industrial production land (or vice versa): a wrong use purpose in the price list can move the unit price several-fold, and it is the most frequent error in successfully challenged notices.
Frequently Asked Questions
What is the formula for annual land rent in Vietnam?
The core formula under Decree 103/2024/ND-CP: Annual land rent payable = Rentable land area (m²) × Land rent unit price (VND/m²/year). The unit price itself is: the Percentage rate (%) for calculating the rent unit price × the Land price for rent calculation (taken from the Land Price List for the corresponding position and use purpose). Provincial People’s Committees issue the percentage rate for each land type and area — a default rate of 1% applies where the locality has not issued a specific rate, under Article 33 of Decree 103/2024/ND-CP. Rent is stabilised in 5-year cycles under clause 2, Article 153 of the Land Law 31/2024/QH15, and the tax authority issues the payment notice.
Where does the land price for rent calculation come from, and when is it reset?
It is the land price in the Land Price List issued by the provincial People’s Committee for the plot’s position and use purpose (Article 159 of the Land Law 31/2024/QH15; from 1 January 2026 the price list is issued annually). The price is fixed when the State decides to lease the land, or reset by cycle: within a stable 5-year cycle the unit price does not change; at the next cycle it is priced off the price list of the new cycle’s first year, with the increase capped at the Government-set rate for each period, not exceeding the cumulative CPI of the preceding five years, per clause 2, Article 153. Note that changes in area, use purpose or detailed planning trigger rent recalculation from the time of change under Decree 103/2024/ND-CP.
Must an industrial park sub-lessee calculate State land rent itself?
Normally not. In the industrial park model under Article 202 of the Land Law 31/2024/QH15, the party paying land rent to the State is the park developer — the name in the land lease decision and on the tax notice. The sub-leasing factory pays sub-lease rent to the developer under its contract (a market price whose composition includes the developer’s land cost). Only where an investor leases land directly from the State (outside a park, or by direct State lease in statutory cases) is the enterprise itself the land rent payer, tracking tax notices, payment deadlines and cycle resets. Confusing the two models is a common error when an in-park company receives tax documents that are not its own.
Is there any way to lock the land rent for longer than 5 years?
For State land rent: no — the 5-year stability cycle and the capped reset mechanism in clause 2, Article 153 of the Land Law 31/2024/QH15 are statutory rules applying to every State land lessee; the parties cannot agree otherwise and the tax authority has no power to promise a longer lock. Long-term price locking is achievable only at two other layers: the commercial layer of an in-park sub-lease — negotiating rent terms with adjustment caps and long adjustment cycles (for example 10 years) with the park developer, because sub-lease rent is an agreed price; or the payment-structure layer — choosing the lump-sum payment option for the whole lease term to eliminate future price movement entirely, in exchange for large upfront capital cost and locked-in capital risk if the project changes. Enterprises must distinguish these two ‘rents’ clearly when reading any price-lock promise in investment promotion materials.
