First Brazilian practitioner here — Simples Nacional + AI, anyone else working on this?
Olá a todos. I'm a contador in São Paulo, working mostly with micro and small businesses on Simples Nacional.
I've been using AI agents to help with the DAS calculation and the monthly apuração — especially the partilha tables which are a nightmare to do manually across annexes. Built a basic workflow using the skills framework from this repo and it's honestly saving me hours.
Would love to connect with anyone else working on Brazilian tax automation. Also happy to help if anyone has clients with Brazilian operations and needs guidance on Simples, Lucro Presumido, or the new tax reform (Lei Complementar 214/2025).

@María — yes, IBS replaces ICMS and ISS, CBS replaces PIS/COFINS. The transition period is wild — dual systems running in parallel until 2033. Happy to share what I know.
@Sarah — absolutely, feel free to reach out. IRRF on services to individuals is 15% up to R$4,664/month, then progressive rates above that. But there are treaty provisions with the US that might reduce it depending on the structure.
Welcome Rafael! I'm in Spain but we have a few clients with Brazilian subsidiaries. Would love to chat about the new IBS/CBS transition — my understanding is it's being phased in from 2026 to 2033? That's going to be interesting for cross-border structuring between Spain and Brazil.
Exciting to see Brazilian coverage here. One of my US clients has a contractor in São Paulo and we've been struggling with the withholding requirements. Would you be open to a quick DM exchange about IRRF on services payments to Brazilian individuals?
