End of ICMS Tax Incentives: The Decision Before 2029

The tax reform phases out ICMS tax incentives on a sliding scale: they shrink by 10% per year between 2029 and 2032 and disappear in 2033, together with the tax itself (art. 128 of the ADCT, added by EC 132/2023). For industries that today operate on the back of a state benefit, three routes remain — move production to the Manaus Free Trade Zone, the only regional regime preserved through 2073; obtain approval under the Tax Benefits Compensation Fund (FCBF), filing through e-CAC by December 2028; or absorb the loss and reprice. The choice is not only fiscal: simulations cited by Valor Econômico indicate that, as early as 2030, manufacturing a smartphone in Minas Gerais will cost 26.5% more in taxes than producing it in the Manaus hub.

This analysis is part of the calendar of tax reform planning windows — the schedule of decisions that the transition opens and closes, one by one, each with a deadline.

The schedule that switches off the fiscal war

For four decades, the location of Brazilian industry was decided, in large part, in the state ICMS decrees. Presumed credit, deferral, reduced base: each state assembled its menu to attract factories, and the country’s industrial map came to mirror those menus. The tax reform ends this model on a fixed date — and the date is closer than most planning assumes.

The mechanism is in art. 128 of the ADCT, added by Constitutional Amendment No. 132/2023. From 2029 to 2032, ICMS (and ISS) rates are fixed at decreasing fractions of the rates set out in each entity’s legislation: nine tenths in 2029, eight tenths in 2030, seven tenths in 2031 and six tenths in 2032. Paragraph 1 of the same article provides that tax or financial benefits and incentives linked to these taxes are reduced in the same proportion. In 2033, ICMS and ISS cease to exist, and with them the legal basis for every state and municipal incentive on consumption.

This design has a consequence that official communications rarely spell out: the cut does not wait for 2033. A company with 30% of its operating margin resting on a presumed ICMS credit loses 3 points of that margin as early as 2029 — and the rest in annual installments, with contracts, prices and logistics still calibrated for the old world. The full reading of the general timeline is in the reform’s transition period.

Why there is no “renewing the incentive”

In the new system there is no room for a state to rebuild the benefit on its own. The IBS has a single national legislation, a reference rate and management by the Steering Committee — a federative entity may set its own rate, but it can no longer grant an individual advantage to a company or sector without constitutional backing. That is why the discussion moved from the state cabinets to two federal addresses: the FCBF, which compensates those who lose, and the Manaus Free Trade Zone, which remains as an express exception.

Why production tends to concentrate in Manaus

On June 10, 2026, Valor Econômico published the report “Tax reform will concentrate production in Manaus”, consolidating what market simulations had been signaling: with the end of state incentives, the manufacture of electronics outside the Manaus Free Trade Zone tends to lose viability. The report’s summary example: as early as 2030, still mid-transition, the total tax cost of manufacturing a smartphone in Minas Gerais will be 26.5% higher than producing it in the Manaus Industrial Hub — where the benefits remain assured for the term of art. 92-A of the ADCT, projected through 2073.

The asymmetry does not stem from a single provision, but from the sum of three:

The movement already shows up in the institutional figures: Suframa estimates that the Manaus Industrial Hub will receive more than 200 new factories over the next three years, between projects approved by the Board of Administration and under implementation — growth on the order of 30% over the roughly 600 current companies, with interest concentrated in electronics, two-wheelers, climate control and pharmaceuticals.

The counterpoint recorded by the report itself deserves to stay on the radar of those deciding. For Abinee, the reform on its own should not make production outside the hub unviable — the problem is the combination of the end of state incentives with the preservation of robust and exclusive mechanisms in Manaus. And there is the practical warning that there is no general rule: the calculation must be done company by company, product by product, and not every operation has the logistics or product profile compatible with the move. It is precisely this case-by-case math that structures the three routes below.

Route A — Move production to the Manaus Free Trade Zone

The first route is the one that gives the Valor report its title: take industrialization inside the regime that survived. It is the most powerful in terms of tax burden — and the most demanding in terms of substance.

The gain comes in layers. Operations internal to the hub with a zero IBS and CBS rate; presumed credits on output (CBS of 6% for products whose IPI rate was below 6.5% in December 2023, and 2% for the others; IBS by category of goods); and, on the side of the competitor that stayed out, IPI kept in place working as a barrier. The set is in arts. 439 to 458 of LC 214/2025, as amended by LC 227/2026, and was detailed piece by piece in our guide to the Manaus Free Trade Zone in the tax reform.

The conditions, however, filter candidates:

• Real industrial substance. The incentive is anchored in compliance with the Basic Production Process (PPB). Symbolic assembly to capture the benefit is the classic target of challenge — and tends not to survive a substance review.
• Product profile. The advantage is greater for goods with a historical IPI rate equal to or above 6.5% and equivalent incentivized production in the hub. For new products with no domestic counterpart, there are additional filters.
• Logistics. The fiscal gain must outweigh the cost of bringing in inputs and shipping production out from the Amazon — for chains heavily dependent on proximity to the consumer market, the math may not add up.
• Short-term uncertainty in the percentages. The presumed credits of art. 450 are under a FIESP public civil action (ACP No. 1049079-37.2026.4.01.3400), which seeks the suspension of §§ 1 and 2. The 2073 horizon gives the regime predictability; the exact percentages may be recalibrated.

The move usually makes sense for those who combine three conditions: a product protected by the retained IPI, scale that dilutes the logistics cost, and an investment horizon long enough to capture the predictability through 2073. For multinationals that import from a parent company abroad, the same analysis speaks to the decision of where to locate the Brazilian industrial stage.

Route B — Stay where you are and qualify for the FCBF

The second route is for those who will not (or cannot) move: turning the dying incentive into compensation. The Tax Benefits or Financial-Fiscal Benefits Compensation Fund (FCBF) was created by EC 132/2023 precisely to compensate the holders of onerous ICMS benefits granted for a fixed term and under condition — those in which the company assumed obligations (investment, employment, minimum revenue) in exchange for the incentive. The constitutional provision is for federal contributions on the order of R$ 160 billion between 2025 and 2032, with compensation paid between January 1, 2029 and December 31, 2032, tracking the staggered reduction of art. 128.

The entry door is administrative and has a deadline. RFB Ordinance No. 635/2025, published on December 31, 2025, regulated the qualification process: an electronic request through e-CAC, one request per type of benefit, between January 1, 2026 and December 31, 2028, with the Federal Revenue Service publishing a “declaration of eligibility” per state incentive program. Absent a ruling by the tax authority within 120 days (or 240, in cases without prior analysis), eligibility is granted automatically from January 2029. A denial may be appealed administratively under the procedure of Law No. 9.784/1999 (arts. 56 to 59) — therefore outside the scope of CARF.

Four points of attention separate those who will receive from those who will litigate:

1. The concept of onerousness is in dispute. The ordinance detailed evidentiary criteria (investments, jobs, economic impact) that tax lawyers consider more restrictive than LC 214/2025 authorizes. Infralegal rules narrowing a concept set by a complementary law are fertile ground for judicial challenge — and for mass denials of those who file poorly.
2. The analysis is by program, not by company. If the first request relating to a state incentive is poorly prepared and that program’s eligibility is denied, the following requests from other companies in the same program tend to be rejected as a block. There is a real strategic incentive to enter early and enter well.
3. The funds may not be enough. Qualification does not guarantee an amount: the distribution will depend on the universe of qualified holders. One more reason not to leave the filing for 2028.
4. Documentation is the whole game. Granting act, agreement term, proof of the obligations fulfilled, the benefit’s calculation memorandum — the file must reconstruct the onerous relationship from its origin. Companies with weak documentary governance arrive in a fragile position.

One detail that changes the posture: qualifying for the FCBF and studying the move are not mutually exclusive. The compensation covers the loss of the past-present benefit; the footprint decision looks to 2033 onward.

Route C — Absorb, reprice and restructure

The third route is the default for those who do not act — and, for some profiles, it is legitimately the best. Companies whose incentive is not onerous (no right to the FCBF), whose product has no IPI protection or counterpart in the hub, or whose logistics make Manaus unviable, will manage the loss in-house. The work here is less glamorous and more urgent than it seems:

• Repricing in waves. The 10%-per-year loss of the benefit must enter price formation from 2029 to 2032 — waiting until 2033 to readjust all at once is handing margin to the competitor that planned ahead.
• Review of long contracts. Supply agreements running beyond 2029 need a tax rebalancing clause that captures the transition (anyone who sold a fixed price through 2032 with a margin calculated on a presumed credit signed their own loss).
• Footprint reassessment without dogma. Sometimes the answer is not Manaus, but rather consolidating plants, renegotiating remaining obligations with the state, or repositioning the mix toward less exposed products.
• Cash and transition credits. The coexistence of residual ICMS + IBS between 2029 and 2032 creates credit balances and flow asymmetries — and the past also has a bill to pay: PIS/Cofins credits from the last five years must be audited before the extinction in 2027.

The most exposed sectors are those that historically made the most use of the fiscal war: electronics and durable consumer goods, auto parts, packaging, and technology operations with a manufacturing stage benefited by state IT policies — the case of Minas Gerais, named explicitly in the Valor report.

How to decide: the three-route matrix

The starting question is not “is it worth going to Manaus?”, but rather “how much of my margin relies on an incentive that is going to die — and when?”. From there, TaxUp models the three routes on the same dashboard, year by year, from 2027 to 2033:

Routes A and B can (and often should) be pursued in parallel. The common mistake is to treat the issue as a 2032 agenda: all three routes have triggers between 2026 and 2028.

“The incentivized industrial company has three clocks running at the same time: the benefit that begins to shrink in 2029, the qualification to the fund that closes in 2028, and the investment decision that needs two years to become a factory. Whoever looks only at the 2033 clock will miss the other three.”
