Before Sea-Tac, before the classroom, there was a ledger. Marcio spent nineteen years in Brazil on the finance and administration side of two very different institutions, a hospital and later a publishing house, before earning his Tecnólogo diploma in Finance Management from UNINOVE and registering with CRA-SP, Brazil's regional council governing the Administration profession. Moving to the United States in 2012 didn't end that career. It split it in two.

Teaching business and finance to adult learners in California kept one foot in accounting. Founding AskMarcio.com and Serafim Dpaulla Consultancy in 2010 kept the other foot in Brazil. TSA is the day job now. Cross-border accounting is the practice Marcio keeps deliberately sharp, not from memory, but by staying active inside two real firms, one in São Paulo and one in California.

Ask any Brazilian accountant where the real workload lives, and the answer is always the same: o departamento fiscal, the fiscal department. It's a different job from bookkeeping. Bookkeeping records what happened. The fiscal department exists because Brazil requires a company to prove, continuously and in digital form, that what happened was reported correctly, on time, in the right format, to federal, state, and municipal authorities at once.

SPED, Brazil's Public System of Digital Bookkeeping, is what makes that proof possible: twelve linked modules in total, five real-time transaction documents like NF-e and CT-e, and seven periodic filings, including eSocial, ECD, ECF, EFD-Contribuições, EFD-ICMS/IPI, EFD-Reinf, and e-Financeira, all cross-checked by the tax authority's own systems as they arrive.

2026 raises the stakes further. It's the first live test year of Brazil's tax reform. Companies now calculate and report two brand-new taxes, CBS and IBS, in parallel with the ones being phased out, PIS, COFINS, ICMS, and ISS, a transition that runs through 2033. Staying fluent in Brazilian fiscal work this year means learning a second tax system while the first one is still fully active. It's exactly the kind of demand that keeps Marcio's own knowledge current instead of theoretical.
