ICMS recovery.
State windows before 2033.

Credits on electricity and communication

Industrial companies are entitled to an ICMS credit on electricity consumed in production (Complementary Law 87/96, art. 33). The base is the ICMS paid on the energy bill (the rate varies by state, generally 18-25%). For companies with high electricity consumption (meatpacking, steel, chemicals), the recoverable credit over the last 5 years can reach BRL millions.

Communication has a more restrictive rule — only services directly related to the economic activity generate a credit. But there are still specific theses for telecom and media companies and companies with large call centers.

Frequent errors that generate credit

• An industrial company not crediting ICMS on energy (thinking it needed specific proof)
• Credit limited to 1/12 or 1/48 when it should be full
• Energy consumed in an administrative center wrongly classified as “non-production”

Credit on fixed assets (Complementary Law 87/96)

The purchase of machinery, equipment and fixed-asset goods of an industry generates an ICMS credit, used over 48 monthly installments (1/48 per month). It has been a taxpayer right since 1996.

Companies that grew through investment in their industrial plant over the last 5 years frequently have unused credits — through lack of awareness, wrong ERP configuration, or an accounting-classification error between fixed assets and operating expense.

How to recover

An audit of the ECD (Digital Accounting Bookkeeping) cross-checked with SPED-Fiscal over the last 5 years. Identification of fixed-asset acquisitions and validation of the monthly 1/48 crediting. Differences generate accumulated credit recoverable via SPED or a state PER/DCOMP.

DIFAL — interstate rate differential

DIFAL applies when a company sells to an end consumer in another state. The current rule: a company in state A sells to an individual customer in state B, collecting ICMS at state A’s internal rate + ICMS in state B for the differential up to state B’s internal rate.

There are several theses for recovering overpaid DIFAL:

• DIFAL charged before Complementary Law 190/2022 (STF Theme 1.093 — on re-trial)
• DIFAL not respecting the 90-day anteriority
• Contested “inside” calculation (with ICMS in its own base)
• Error in the destination state’s internal rate

With IBS replacing ICMS in 2029, DIFAL ceases to exist. The recovery window is open until the five-year statute of limitations of each operation.

ICMS on exports (immunity + reimbursement)

Exports are immune to ICMS (Federal Constitution, art. 155 §2 X “a”). But the exporting company pays ICMS in the prior chain (inputs, energy, freight) — that accumulated credit should be reimbursed by the state.

In practice, states resist reimbursement, and exporters accumulate an ICMS credit balance for years. Recovery strategies include:

• Administrative reimbursement request to the state (slow and partial)
• Offset against the same taxpayer’s debits in other operations
• Transfer of credits to third parties (allowed in some states, at a discount)
• Writ of mandamus against a state that refuses reimbursement

Recovery window until 2033

ICMS will remain in force until 2033 — when it is fully replaced by IBS. During 2026-2028, ICMS is at full rates; during 2029-2032, there is a phase-down with IBS rising and ICMS decreasing. Each company will have its own transition cycle.

The recovery of retroactive ICMS credits can be done until the five-year statute of limitations of each operation. For example: ICMS paid in May 2024 is time-barred in May 2029 — a company can recover until 2029, even if ICMS is already in phase-down.

It is advisable to prioritize the diagnosis during 2026-2027, before the complex phase-down begins in 2029.
