TaxUp Reform Index v1: a national diagnostic of corporate readiness.

Why this study exists

The Brazilian Tax Reform (Constitutional Amendment 132/2023, regulated by Complementary Law 214/2025 and subsequent legislation) takes effect progressively between 2026 and 2033. It is the largest structural change to the Brazilian tax system in three decades — it replaces PIS, COFINS, IPI, ICMS and ISS with two new taxes (the state/municipal IBS and the federal CBS) built on full non-cumulativity, creates the Selective Tax on goods harmful to health and the environment, and introduces split-payment as an automated collection mechanism.

Despite the volume of press coverage and abundant academic output, a notable gap remains: there is almost no primary data on how Brazilian companies are actually preparing. Existing surveys are fragmented (industry associations with small samples), dated (predating the infra-constitutional regulation) or biased by their source (consultancies publishing to promote services).

The TaxUp Reform Index v1 sets out to fill that gap with structured research covering technical readiness (NF-e 5.0 adaptation status, IBS/CBS impact modeling, team training), decision readiness (the 2027 Simples decision, investment planning) and strategic readiness (views on the timeline, expected impact, intent to engage a consultancy).

Methodology

• Universe: Brazilian companies with gross annual revenue from BRL 10M to BRL 1B (mid-market and large non-financial companies). Includes multinationals with a Brazilian subsidiary in this profile.
• Target n: 200 to 300 valid responses (after filtering for duplicates and eligibility).
• Collection: Online questionnaire in anonymous format (with the option to self-identify to receive the exclusive report). Distribution via LinkedIn outreach, direct email and partnerships with industry associations.
• Collection window: 30 calendar days. Expected close: around June 5, 2026.
• Statistical analysis: Distributions by sector (12 categories), size (7 revenue bands), tax regime, capital origin and region. Cross-tabs between technical readiness and company profile.
• Confidentiality: Individual data is not shared. Only aggregate statistics appear in the final report. Processing in accordance with the LGPD (Law 13.709/2018) and the TaxUp Privacy Policy.
• Declared biases: The sample tends to over-represent companies whose owners/CFOs are active on LinkedIn and within the TaxUp network. This is openly disclosed in the final report and factored into the conclusions.
