Brazil’s recent tax reform opened a brief planning window for owners of real-estate assets, especially those considering a holding company to consolidate property. The window closes on 31 December 2026, after which the tax benefits tied to the transition rules disappear.
Transition rules set a temporary advantage
The reform introduced the IBS (Imposto sobre Bens e Serviços) and the CBS (Contribuição Social sobre Bens e Serviços), replacing the old tax regime for real-estate transactions. Complementary laws LC 214/25 and LC 227/26 created a “reference value” for each property, calculated by tax authorities using market data, and an “adjustment reducer” that can lower the taxable base when the property is later sold.
Article 256 of LC 214/25 defines the reference value, while article 257 establishes the reducer, and article 258 explains its computation. For properties owned on the cut-off date, owners may elect to use the reference value instead of the historic acquisition cost when determining the reducer. This election is the core of the planning opportunity.
Why 2026 is a strategic year for a holding
When transferring real estate into a holding, article 23 of law 9.249/95 allows the contribution to be recorded at the value declared in the owner’s income tax return – essentially the original purchase price. This avoids immediate capital-gain tax on the difference between the historic cost and today’s market price.
Later, when the holding sells the asset under the new IBS/CBS regime, the reducer can be based on the reference value, which often exceeds the historic cost. The higher reducer shrinks the taxable base, reducing the tax due on the sale.
In practice, this strategy lets a taxpayer defer capital-gain tax and benefit from a larger reducer reflecting current market conditions. The combination of deferral and a potentially larger reducer makes the period before the end of 2026 uniquely attractive.

After 1 January 2027, any property acquired by a legal entity, even through integration, will have its reducer calculated solely from the acquisition cost. The optional use of the reference value will no longer be available for assets entering the holding after the deadline.
While the holding structure remains useful for governance and succession planning, the specific tax advantage tied to the transition rules is time-bound. Families with significant real-estate holdings, investors who rent out properties, and business owners planning to sell assets in the coming years should assess the window carefully.
One caution is that the benefit depends on accurate determination of the reference value and proper documentation of the integration. Errors in either step could trigger tax authority challenges, potentially erasing the anticipated savings.
The legislation also sets detailed rules for how the reducer is allocated when properties are split, merged, or involved in partnership agreements. These provisions aim to preserve the reducer’s value across various restructuring scenarios.
For eligible owners, 31 December 2026 is the last day to secure the optional reference-value reducer. After this date, the tax environment will change, requiring a reevaluation of planning strategies.
How the reference value is established
Tax administrations must apply a specific methodology to estimate each property’s market value. This process combines analysis of actual negotiated prices in the real-estate market, data from municipal, state, federal, and district tax bodies, and information from registries and notary offices. The valuation is then recorded in the National Territorial Information Management System (Sinter), where it becomes publicly accessible.
Registries and notaries are required to transmit property transaction details to tax authorities through Sinter, ensuring the reference value reflects recent market conditions and maintains uniformity across jurisdictions. Taxpayers may challenge the calculated figure through a dedicated procedural channel, allowing re-assessment if the estimate is deemed inaccurate.

Rules governing the adjustment reducer
The adjustment reducer’s monetary amount is periodically updated from its creation until IBS and CBS become due on a future sale, using the IPCA index or any successor. This preserves the reducer’s purchasing power over time, preventing inflationary erosion.
When properties are combined through merger, unification, or consolidation, the resulting asset’s reducer equals the sum of the individual reducers. In cases of subdivision, parceling, or dismemberment, the total reducer is allocated among the new parcels proportionally to their market values; if market values cannot be determined, allocation follows the proportion of each parcel’s area.
Partnership contracts for land-development projects also incorporate the reducer, applied proportionally to each partner’s share based on percentages in the agreement. Even without detailed regulations, the legislation confirms the reducer’s permissible application.
For properties under construction on the cut-off date, the initial reducer combines the updated acquisition cost of the land, the updated cost of the building already erected, and, where applicable, documented expenses related to production or commercialization, provided they are supported by fiscal documents. This approach captures the unfinished asset’s accumulated value.
If the reference value is unavailable at the cut-off moment, taxpayers not electing the default acquisition-cost option may calculate the reducer using a market-value estimate generated through the regulation’s specific procedure. This prevents a lack of reference data from nullifying the planning advantage.
Tax authorities may review declared acquisition values. If documentation or declarations appear inconsistent with market reality, an administrative process may be initiated to determine the effective acquisition cost for the reducer, respecting due process.
