​English: ​Tax Reform Executive Summary

What happened? Brazil has launched a historic overhaul of its consumption tax system, moving from a fragmented model to a modern Dual VAT system. Starting in 2026, five current taxes (PIS, Cofins, IPI, ICMS, and ISS) will be phased out and replaced by CBS (federal) and IBS (state and municipal). 2026 is designated as a "test year" with a reduced rate of 1% to calibrate systems and allow the tax authorities to monitor taxpayer behavior. Although the initial financial impact is minimal, operational compliance is mandatory: invoices must include these new tax fields starting August 2026 or they will be automatically rejected by the system.

What is the impact? This is more than a tax rate change; it is a fundamental shift in business operations. Companies will face a multi-year transition period, managing both old and new tax regimes simultaneously until 2033. Taxation will now follow the destination principle (where the product is consumed), ending regional tax wars but requiring precise geographical data for every sale.

The Split Payment mechanism is the most disruptive financial change. At the point of invoice payment, the tax amount is automatically withheld by the banking system and sent directly to the government. This eliminates the "fiscal float" that companies previously enjoyed. Additionally, the new system introduces conditional credits: a buyer can only claim a tax credit if the supplier has effectively paid the tax in the previous transaction.

Practical Example Imagine a retail company purchasing inventory. Under the new rules, if the supplier is a "tax debtor" or fails to settle its IBS/CBS obligations, the retail company will be blocked from claiming the tax credit for that purchase. This links the buyer's fiscal health directly to the supplier's compliance, making supply chain auditing a financial necessity.

What to do now?

1. Data Sanitation: Audit all product and service tax codes (NCM/NBS) immediately to prevent automatic errors in tax calculation.
2. ERP Readiness: Ensure your management software is updated for new invoice layouts and real-time API integrations with tax authorities.
3. Liquidity Planning: Adjust working capital projections for the Split Payment era, as tax money will no longer pass through your company's accounts.
4. Supplier Due Diligence: Implement strict monitoring of your suppliers' fiscal status to ensure their non-compliance does not jeopardize your tax credits.
