Forestry in Uruguay: qualified plantations, twelve year tax benefits, IRAE limits, native forest protection and land ownership rules

Last verified: 2026-10-27 · Status: Stable

Plantations classified by the Ministry of Livestock, Agriculture and Fisheries as protective, or as yield forests in forestry priority zones, are exempt from national rural property taxes and the rural Contribución Inmobiliaria and are excluded from the net worth tax base, for 12 years from planting (Ley Nº 15.939 art. 39 and 43). The IRAE exemption on forest income does not apply to yield plantations established after the 2006 tax reform unless they belong to quality wood projects, and since Ley Nº 20.446 the benefits do not reach the new Domestic Minimum Complementary Tax. Cutting native forest is prohibited without authorisation, benefits need an approved management plan, and companies owning rural land must have registered shares held by individuals or Executive authorisation (Ley Nº 15.939 art. 24 and 49; Ley Nº 18.092 art. 1).

The rule

1. Private forests are classified as protective (mainly to conserve soil, water and other natural resources), yield (mainly to produce wood or other forest products of special national interest) or general. The forestry directorate classifies protective and yield forests on its own initiative or on request, with a report for existing forests or a forestation project for new ones, and keeps registers of them. Forestry land includes land declared of forestry priority by Ministry resolution. Forest leases and sales of standing forests can be registered in the Registro de la Propiedad Inmueble and are effective against third parties from registration.
Cost to do it: Classification requires a forestation project or report prepared by the applicant; registry fees for leases follow the general real estate registry.
Example: A fund leasing land for eucalyptus can register the forest lease so it binds a later buyer of the land. / Same in USD.Ley Nº 15.939 (Forestry Law) of 28 December 1987; art. 9 paragraph 2 added by Ley Nº 17.555 art. 77, Art. 5, 8 and 9, 2002-09-18 official text · verified 2026-10-27

2. Protective plantations, yield plantations in forestry priority zones and protective native forests, with the land they occupy, are exempt from all national taxes on rural real estate and from the rural Contribución Inmobiliaria, and their value or area is excluded from the net worth tax base. These exemptions extend to future taxes on agricultural activity, last 12 years from planting, and do not cover the Impuesto Mínimo Complementario Doméstico.
Cost to do it: No fee; benefits require classification and an approved management plan.
Example: A yield plantation established in 2020 in a priority zone keeps the property tax exemptions until 2032. / Same in USD.Ley Nº 15.939 art. 39 and art. 43 as worded by Ley Nº 20.446 art. 669, Art. 39 and 43, 2025-12-16 official text · verified 2026-10-27 · changed: Ley Nº 20.446 of 16 December 2025, art. 669, reworded art. 43: the 12 year term from planting stays and the benefits expressly do not cover the Impuesto Mínimo Complementario Doméstico.

3. Income from exploiting qualified forests is not computed for IRAE. The exemption does not apply to yield plantations established after Ley Nº 18.083 came into force, except forests in quality wood projects defined by the Ministry. The exemption covers debarking, cutting and chipping on own forests (grown or bought standing) and, under conditions, on timber bought from third parties if third party timber sold in the year is below one third of own forest stock.
Cost to do it: Where the exemption does not apply, IRAE is 25 percent of net income (Title 4 art. 23).
Example: A yield plantation planted after the reform outside a quality wood project earning UYU 40,210,000 of net income pays IRAE of UYU 10,052,500. / On US$1,000,000 of net income, US$250,000 of IRAE.Texto Ordenado 2023 (Decreto Nº 101/024), Title 4, from Ley Nº 18.083 art. 3, Title 4 art. 93, 94 and 95, 2006-12-27 official text · verified 2026-10-27

4. IRAE taxpayers may deduct from the tax payable a percentage of the cost of planting protective or yield forests in priority zones, on conditions set by the Executive based on the notional forestation cost.
Cost to do it: Percentage and notional cost are set by the Executive, not by the law.
Example: The deduction reduces IRAE payable rather than taxable income. / Same in USD.Texto Ordenado 2023, Title 4 (from Ley Nº 15.939 art. 50), Title 4 art. 97, 2006-12-27 official text · verified 2026-10-27

5. To obtain the tax and financing benefits, the holder must file a management and harvesting plan approved by the forestry directorate and signed by an agronomist, forestry engineer, or a forestry technician from the listed public schools. Benefits end when the forest is destroyed for any reason; if destruction is intentional or by gross negligence of the owner, deferred taxes become payable with late payment surcharges.
Cost to do it: Professional fees for the signed management plan; surcharges if benefits are lost through the owner's fault.
Example: A plantation burned through gross negligence loses its benefits and owes the deferred taxes with surcharges. / Same in USD.Ley Nº 15.939 art. 49 as worded by Ley Nº 20.007 art. 1, and art. 40, Art. 40 and 49, 2021-11-25 official text · verified 2026-10-27

6. Destroying protective forests is prohibited; any operation not following the management plan that threatens the forest counts as destruction and requires reforestation. Cutting and any operation against the survival of native forest (monte indígena) is prohibited except for domestic use and fencing of the farm it belongs to, or with authorisation of the forestry directorate based on a technical report. Destroying natural palm groves is also prohibited. Forestry infringements are sanctioned under Ley Nº 16.736 art. 285.
Cost to do it: Authorisation for native forest cutting requires a technical report; sanctions follow Ley Nº 16.736 art. 285.
Example: Clearing native forest to plant eucalyptus without authorisation is prohibited. / Same in USD.Ley Nº 15.939 art. 22, 24, 25 and 69 (art. 69 worded by Ley Nº 20.075 art. 191), Art. 22, 24, 25 and 69, 2022-10-20 official text · verified 2026-10-27

7. Owners of rural land and agricultural businesses must be individuals, partnerships, agrarian companies, cooperatives or public entities; companies may hold rural land if all their capital is registered shares or quotas owned by individuals. The Executive may, on request, authorise other companies, branches of non resident entities, trusts and investment funds to hold rural land when the number of shareholders or nature of the business prevents ownership solely by individuals; the authorisation lists the specific properties and must be renewed whenever the area increases or properties change.
Cost to do it: No fee set by the law; the authorisation is property specific.
Example: A listed forestry company owned through funds needs Executive authorisation for each farm it buys. / Same in USD.Ley Nº 18.092 art. 1 as worded by Ley Nº 18.172 art. 349, Art. 1, 2007-08-31 official text · verified 2026-10-27

8. Forestry producers and wood processing businesses could import raw materials, equipment and machinery free of customs duties and charges on Executive exemption, for 15 years from the law's promulgation on 28 December 1987.
Cost to do it: Not available on the original terms: the 15 year window counted from 28 December 1987 has run.
Example: New sawmills should look to COMAP investment promotion instead. / Same in USD.Ley Nº 15.939, Art. 65 and 66, 1987-12-28 official text · verified 2026-10-27

Tax position of a qualified plantation

Worked example

IRAE on a post reform yield plantation: net income of US$1,000,000 (UYU 40,210,000) from a eucalyptus plantation planted after Ley Nº 18.083 outside a quality wood project pays IRAE of US$250,000 (UYU 10,052,500), while the land keeps the 12 year property tax exemptions if classified (T.O. 2023 Title 4 art. 23 and 93; Ley Nº 15.939 art. 39 and 43).
Ownership structure: a foreign forestry fund buying farms through a Uruguayan S.A. must either have registered shares owned by individuals or obtain Executive authorisation listing each farm (Ley Nº 18.092 art. 1).

Step by step

1. Check the land's forestry priority status and soil (Ley Nº 15.939 art. 5) and any departmental rules.
2. Structure ownership for Ley Nº 18.092: individuals' registered shares or Executive authorisation per property.
3. File the forestation project with the forestry directorate for classification as protective or yield (art. 8).
4. Have the management plan signed by a qualified professional and approved (art. 49).
5. Register forest leases or standing forest sales in the Registro de la Propiedad Inmueble (art. 9).
6. Model IRAE without the exemption unless the project is quality wood, and plan for the Impuesto Mínimo Complementario Doméstico if the group is in scope.

Common traps

Do not assume income tax exemption for new yield plantations: it was removed for plantings after Ley Nº 18.083 unless quality wood (T.O. 2023 Title 4 art. 93).
The 12 year benefit term runs from planting, not from acquisition by a later buyer (Ley Nº 15.939 art. 43).
Benefits are lost on destruction, with surcharges if the owner was at fault (art. 40).
Executive authorisation under Ley Nº 18.092 must be renewed for each additional or substituted property.
Large multinational groups cannot use forestry benefits against the Impuesto Mínimo Complementario Doméstico (art. 43 as worded by Ley Nº 20.446).
