LC 227/2026 Explained — Brazil's ITCMD Reform

LC 227/2026 Explained — Brazil’s ITCMD Reform

Lei Complementar 227/2026 is Brazil’s comprehensive reform of inheritance and gift taxation (ITCMD), enacted to implement the constitutional amendments introduced by EC 132/2023. The law mandates progressive ITCMD rates across all states, establishes market value as the mandatory tax base, introduces taxation of trusts and trust-like structures, expands donation aggregation rules, and — most critically for foreigners — authorizes ITCMD on inheritances and donations involving assets located abroad. LC 227/2026 represents the most significant change to Brazilian succession taxation in three decades.

What Are the 5 Key Changes in LC 227/2026?

1. Progressive Rates Are Mandatory. All states must replace flat ITCMD rates with progressive structures — art. 156: “As alíquotas do ITCMD: I - serão progressivas em razão do valor do quinhão, do legado ou da doação; e II - observarão a alíquota máxima fixada pelo Senado Federal.” Its § 2º makes the application marginal, band by band. Note where the ceiling comes from: it is fixed by resolution of the Federal Senate (CF art. 155, § 1º, IV), not by the Constitution itself — a distinction this page previously blurred by calling 8% a “constitutional maximum”. The Senate ceiling is conventionally given as 8% (Resolução do Senado 9/1992); we have not been able to retrieve the resolution’s article text from a primary source, so treat the mechanism as settled and the number as the one in general use.

2. Market Value Is the Standard. Art. 152 requires ITCMD to be calculated on the market value (valor de mercado) of transferred assets — not assessed values, book values, or declared values. (Art. 153 governs financed assets and art. 154 the valuation of quotas and shares; earlier versions of this page attributed the general market-value rule to art. 154.) This closes the valuation gap that reduced effective ITCMD rates by 30-60%.

3. Trusts and Trust-Like Structures Are Taxable. Arts. 147, 148 § 1º and 151 bring trusts and trust-like contracts expressly within the charge — a category previously unaddressed in Brazilian tax law — with the taxable event at the change of title to the beneficiary or the settlor’s death, whichever comes first (causa mortis if by death, gift if during the settlor’s life). This affects every American in Brazil with a US revocable trust, irrevocable trust, or family trust holding assets for their benefit.

4. Donation Aggregation — over the period YOUR STATE sets, not a federal five years. Art. 155, I aggregates successive donations between the same donor and donee “no prazo definido na legislação tributária estadual ou distrital”. Earlier versions of this page described a federal “5-year rolling window”. Five years is the common state period, including in São Paulo practice, so the number is often right in fact — but it is not what the complementary law says, and it is not uniform across the 27 jurisdictions. Check the state statute that governs your donor–donee pair.

5. Foreign Assets Are Now Jurisdictionally Covered. Arts. 158 and 159 set the competence rules where the donor, the deceased or the assets are abroad, and art. 148, § 1º the incidence. Together with the transitional rule in EC 132/2023, art. 16, they supply the complementary legislation whose absence had blocked those assessments. Brazilian residents inheriting from abroad now owe ITCMD to their state of domicile.

How Did We Get Here? Timeline of the Reform

“LC 227/2026 is the most consequential change to Brazilian succession taxation since the 1988 Constitution. Every American in Brazil with a trust, holding company, or foreign inheritance needs to reassess their plan before state implementation begins.” — Zachariah Zagol, OAB/SP 351.356

Key point: LC 227/2026 establishes the federal framework, but each state must pass its own implementing legislation. The rates, brackets, and exemptions will vary by state. States that already have progressive rates (RJ, SC, BA) need only minor adjustments. States with flat rates (SP, MG, PR) require significant legislative changes.

What Does Each Key Article Change?

Arts. 146-151: Trust Provisions

These articles are unprecedented in Brazilian tax law. They define how ITCMD applies to trusts — a legal concept that does not exist in Brazilian civil law but is ubiquitous in Anglo-American estate planning.

Before LC 227/2026: No specific rules. Tax authorities sporadically attempted to tax trust distributions as donations, with inconsistent results. Many American expats held assets in US trusts with no Brazilian ITCMD consequence.

After LC 227/2026:

“The trust provisions in Arts. 146-151 effectively ended the argument that US trusts were invisible to Brazilian tax authorities. If you have a revocable trust and live in Brazil, the planning window to restructure is measured in months, not years.” — Zachariah Zagol, OAB/SP 351.356

Impact on American expats: If you have a US revocable living trust — the most common American estate planning vehicle — your Brazilian ITCMD exposure has fundamentally changed. The trust assets are now explicitly included in your estate for ITCMD purposes. If you have an irrevocable trust that makes distributions to you in Brazil, each distribution may trigger ITCMD as a donation. See our trust advisory service for restructuring guidance.

Art. 152: Market Value as Tax Base (and Art. 154 for Quotas and Shares)

Art. 152 mandates that the ITCMD tax base be the valor de mercado (market value) of the transferred assets. Two neighbouring articles do related work and are easy to confuse with it: art. 153 governs financed assets, and art. 154 governs the valuation of quotas and shares — which is the provision that actually bites on holding-company structures. Earlier versions of this page cited art. 154 for the general market-value rule.

Before LC 227/2026: States used various reference values. In Sao Paulo, the valor venal de referencia for real estate was often 30-60% below actual market value. Many estates used IPTU assessed values (even lower) with little pushback from SEFAZ. Holding company quotas were valued at book value, not the market value of underlying assets.

After LC 227/2026:

Impact on holding companies: The most significant impact is on holding company structures. Previously, transferring real estate worth R$10 million into a holding company and then donating the quotas could result in ITCMD calculated on the company’s book value of, say, R$3 million. Under art. 154, which governs the valuation of quotas and shares, the tax authority can — and will — look through the corporate structure and assess ITCMD on the R$10 million market value.

Arts. 155-157: Donation Aggregation — on the State’s Period

Art. 155, I aggregates successive donations between the same donor and the same donee “no prazo definido na legislação tributária estadual ou distrital”. The aggregation period is therefore set by state law, not fixed federally. Earlier versions of this page described a federal 5-year rolling window; five years is the common state period, São Paulo included, but it is not what the complementary law says and it is not uniform.

Before LC 227/2026: In states with progressive rates, a donor could make annual donations below the threshold for the top bracket, keeping each individual donation in the lowest rate band. A R$5 million gift could be split into 5 annual gifts of R$1 million, each potentially taxed at the lowest progressive rate.

After LC 227/2026: Donations from the same donor to the same donee within the state’s aggregation period are combined for the purpose of determining the applicable progressive rate. Where that period is five years, the R$5 million split over five years would be taxed at the rate applicable to a single R$5 million gift.

Transition rule: Donations made before the effective date of the state’s implementing legislation are not retroactively aggregated. This creates a narrowing window for pre-reform donation planning.

Art. 156: Progressive Rate Mandate

Art. 156 requires all states to adopt progressive ITCMD rates, implementing the EC 132/2023 constitutional mandate, and its § 2º requires them to be applied band by band: “considerado o enquadramento do valor da base de cálculo na faixa inicial e, naquilo que a exceder, na faixa subsequente, e assim sucessivamente.” (Arts. 158 and 159, which earlier versions of this page cited here, are the jurisdiction rules.)

Before LC 227/2026: States could choose flat or progressive rates. Major states like SP (4%), MG (5%), and PR (4%) chose flat rates — effectively making ITCMD regressive, as a R$100,000 inheritance and a R$100 million inheritance paid the same percentage.

After LC 227/2026: All states must implement progressive rate schedules. The maximum is the one fixed by resolution of the Federal Senate (art. 156, II; CF art. 155, § 1º, IV), conventionally 8% under RS 9/1992. Each state designs its own brackets and rates below that ceiling. (A “2% floor for the lowest bracket” appeared in earlier versions of this page. Art. 156 contains only the two items quoted above and we have not located a floor in the complementary law; treat any minimum as a matter for the state schedule until the point is confirmed against the statute.)

Projected SP rate structure (based on legislative proposals):

Note: These brackets are projections based on PL 7/2024 (SP). Final rates depend on the state legislature’s enacted law.

How Does LC 227/2026 Change Jurisdiction Rules for ITCMD?

Before the reform, the jurisdictional rules for ITCMD were fragmented and contested. LC 227/2026, arts. 158 and 159 establish clear competence rules, with the incidence rule in art. 148, § 1º. (Art. 152 is the market-value provision; earlier versions of this page cited it here.)

The practical impact for Americans in Brazil is substantial. A US parent who dies leaving a $3 million IRA to their American child living in Sao Paulo now triggers ITCMD in Sao Paulo — on top of any US estate tax. This creates a new double-taxation scenario that did not exist before 2026. The STF’s 2021 ruling in RE 851.108 had temporarily blocked this taxation, but LC 227/2026 provides the complementary legislation the Court required. For Americans navigating both systems there is no treaty relief of any kind: Brazil and the United States have neither an estate and gift tax treaty nor an income tax treaty. The United States does not appear on the Receita Federal’s list of conventions to avoid double taxation. (Decreto 85.985/1981 is occasionally cited as a Brazil-US convention; it is the Brazil-Italy income tax convention and would not reach estate or gift tax in any event.) The only partial relief is unilateral — the US foreign death tax credit under IRC § 2014, which offsets only the US tax attributable to the Brazilian assets and does not cover state-level estate taxes.

What Are the Anti-Avoidance Provisions?

LC 227/2026 includes several provisions designed to prevent common ITCMD avoidance strategies:

Art. 154 — Valuation of quotas and shares, and look-through for corporate structures: When a holding company’s primary assets are real estate, the state tax authority can value the company’s quotas at the market value of the underlying real estate rather than book value. This directly targets the holding company strategy used by many foreign investors to reduce ITCMD.

Art. 155, paragraph 3 — Sham donation identification: The tax authority can recharacterize transactions structured as sales or loans between family members as donations for ITCMD purposes. The burden of proof shifts to the taxpayer to demonstrate the transaction was genuinely at arm’s length.

Art. 148 — Trust veil-piercing: For trusts where the settlor retains effective control (including US revocable trusts), the tax authority treats the trust as transparent — meaning the assets are treated as directly owned by the settlor for ITCMD purposes.

Art. 157 — Aggregation anti-fragmentation: The aggregation — over the period set by state law under art. 155, I, commonly but not universally five years — specifically targets the practice of splitting donations across multiple calendar years to keep each individual donation in the lowest progressive bracket. The aggregation applies per donor-donee pair, not per transaction.

Who Is Most Affected by LC 227/2026?

American Expats in Brazil

The double impact is severe: (1) your US trust is now visible to Brazilian ITCMD, and (2) inheritances you receive from US relatives are now taxable in Brazil. An American living in Sao Paulo who inherits $2 million from a parent in the US previously owed zero ITCMD. Under LC 227/2026, that inheritance will be taxed at progressive rates — potentially 6-8% — on the full value. That’s R$600,000-R$800,000 in ITCMD on an inheritance that is also subject to US estate tax if the parent’s estate exceeds the federal exemption.

Holding Company Owners

The market value mandate in Art. 154 and the look-through rules for corporate structures reduce the ITCMD efficiency of holding companies. This doesn’t eliminate holding companies as a planning tool — they still offer liability protection, succession management, and income tax advantages — but the pure ITCMD arbitrage is significantly diminished.

Trust Beneficiaries

Americans with beneficial interests in US trusts (revocable or irrevocable) face new ITCMD exposure on distributions. The trust provisions in Arts. 146-151 are broadly drafted and will capture most common US trust structures. Trust advisory is now essential for any American in Brazil who is a settlor, beneficiary, or trustee of a US trust.

Foreign Investors with Brazilian Assets

Investors who hold Brazilian real estate or private company equity through foreign structures face the same market value and progressive rate changes. The holding company restructuring that was common among European and American investors will need to be re-evaluated under the new framework.

Dual Citizens and Permanent Residents

Brazilian-American dual citizens face compounded exposure. As US citizens, they owe US estate tax on worldwide assets. As Brazilian domiciliaries, they now owe ITCMD on inherited foreign assets under LC 227/2026. A dual citizen living in SP who inherits $1M from a US relative could face $0 US estate tax (within exemption) but R$40,000+ in Brazilian ITCMD — a tax that simply did not exist before 2026.

How Does LC 227/2026 Interact with Existing State Laws?

LC 227/2026 is a federal framework law — it establishes the rules that states must follow, but each state retains authority over its own ITCMD rates, brackets, and exemptions. The interaction creates a layered implementation:

Immediate effect provisions: By art. 182, III, every ITCMD provision of LC 227/2026 took effect on publication, 14 January 2026 — the jurisdiction rules (arts. 158-159), the trust framework (arts. 147, 148 § 1º, 151), the market-value base (art. 152) and the progressivity mandate (art. 156) alike. Only art. 76, II, “c” and art. 169 are deferred to 1 January 2027, and neither is an ITCMD provision.

What still depends on your state: the rate. LC 227/2026 does not change any state’s schedule by itself. Each State must legislate its progressive bands, and an increase is subject to anterioridade anual and the ninety-day rule. Until a state enacts its own law the existing rate — a flat 4% in São Paulo under Lei estadual 10.705/2000, art. 16, as at September 2026 — continues to apply. That, and not a federal date, is the planning window.

Transitional rules: LC 227/2026 Art. 160 provides that:

• Inventory proceedings already in progress on the effective date of state legislation follow the old rules
• Deaths occurring before the state’s effective date follow the old rules (even if the inventory is filed after)
• Donations completed before the effective date are taxed at old rates (but count toward the state’s donation-aggregation window under art. 155, I)

What Should You Do Now?

The window between LC 227/2026’s enactment and state-level implementation is the last opportunity for certain planning strategies. Here’s what to prioritize:

Actions for 2026 (Before State Implementation)

Actions for 2027+ (After State Implementation)

Once progressive rates are in effect, the focus shifts to ongoing optimization:

• Annual compliance reviews to monitor state-level implementation and rate changes
• Strategic use of the remaining exemptions and deductions
• Coordination of donation timing with your state’s aggregation window (art. 155, I)
• Marriage regime review to optimize the surviving spouse’s meacao vs. inheritance split
• Cross-border tax credit planning for US-Brazil dual exposure

Frequently Asked Questions

When does LC 227/2026 take effect?

LC 227/2026 itself is already in force as the federal framework. However, ITCMD is a state tax, so each state must pass implementing legislation. The anterioridade principle requires a minimum 90-day waiting period (and usually the start of the next calendar year) after state legislation is enacted. Most states are expected to have new rates effective January 2027, though some may delay into 2028.

Does LC 227/2026 affect existing holding companies?

Yes. The market value standard in Art. 154 applies to future transfers of holding company quotas — including those in companies established before the law. The corporate structure itself is not retroactively taxed, but the next transfer event (death or donation of quotas) will be assessed at market value rather than book value.

Can I still make donations before the new rates take effect?

Yes — and this is the primary planning window. Donations made before your state’s progressive rate legislation takes effect are taxed at current rates. In Sao Paulo, this means a flat 4% until the state implements its progressive schedule (expected 2027). However, post-reform donation aggregation rules (Arts. 155-157) will apply to donations made within 5 years of the effective date, so timing is critical.

How does the trust taxation work for US revocable trusts?

A US revocable living trust — where the settlor retains control over assets during their lifetime — is treated for ITCMD purposes as if the assets are directly owned by the settlor. At the settlor’s death, the trust assets are included in the estate and subject to ITCMD causa mortis. During the settlor’s lifetime, distributions to third-party beneficiaries may trigger ITCMD as donations. The practical effect is that a US revocable trust provides zero ITCMD benefit in Brazil.

What is STF RE 851.108 and why does it matter?

RE 851.108 was a landmark 2021 Supreme Court decision that held states could not tax ITCMD on inheritances and donations involving foreign assets without specific authorization from a federal complementary law. This effectively created a tax-free window for foreign inheritances received by Brazilian residents. LC 227/2026 is the complementary law the STF required — meaning the tax-free window is now closed.

Will the 8% maximum rate increase?

Not without a new Resolução do Senado. The 8% ceiling was set by RS 9/1992 and can only be changed by the Senate. The Receita Federal administers complementary federal reporting but has no authority over the ceiling. There have been proposals to raise it to 16% or 20%, but none have advanced. The current reform focuses on making all states use the existing 8% ceiling through progressive structures, rather than raising the ceiling itself.

Should I move from a high-rate state to a low-rate state?

ITCMD on inheritance is owed to the state of the deceased’s last domicile. If you genuinely relocate from RJ (up to 8%) to a state with lower rates, your estate benefits from the lower rate. However, SEFAZ authorities actively investigate domicile claims, and a change made shortly before death with no genuine connection to the new state will be challenged. The move must be genuine, with demonstrable ties (residence, utility bills, voter registration, CPF address).

How does LC 227/2026 affect life insurance and VGBL plans?

LC 227/2026 does not explicitly address VGBL plans. The prevailing judicial interpretation — that VGBL is an insurance product, not an estate asset — remains intact. However, state tax authorities have been emboldened by the reform’s generally expansive approach and are expected to continue challenging the VGBL exemption, particularly for plans with large balances or recent lump-sum contributions. PGBL plans remain clearly subject to ITCMD, as they are classified as financial investments rather than insurance. The strategic recommendation is to maintain the VGBL classification defense but not rely on it as the sole ITCMD planning strategy.

Does the reform create retroactive tax liability?

No. LC 227/2026 Art. 160 contains explicit non-retroactivity provisions. Inheritances from deaths that occurred before the state’s effective date are governed by the old rules. Donations completed before the effective date are taxed at old rates. However, pre-effective-date donations DO count toward the aggregation window for purposes of calculating the progressive rate on future donations — and that window is the period your state’s legislation sets (art. 155, I: “no prazo definido na legislação tributária estadual ou distrital”), not a federal five years — meaning a large donation made in 2026 could push a 2027 donation into a higher bracket.
