A skill for Claude Code and Codex · Method and business
contador-expert is the skill that turns your AI into a Brazilian tax advisor for anyone selling software, websites, automation and AI: the MEI revenue cap and disqualification rules, migrating to an ME, Simples Nacional (Brazil's simplified tax regime for small businesses), the fator R, CNAE activity codes, pro-labore, profit distributions, NFS-e invoicing (Brazil's electronic service invoice) and ISS service tax (Brazil's municipal service tax) and withholdings. It compares lawful paths by total cost, not by the headline tax rate alone, and flags what still needs confirming with your own accountant.

The problem
Ask an AI a Brazilian tax question with no method behind it, and you get a rule from the wrong year, a CNAE code picked by name alone, and a calculation that ignores payroll, ISS and withholding. Three symptoms, and what changes with the skill.
| Without the skill | With contador-expert |
|---|---|
| You ask if it's worth leaving the MEI, and you get the Simples Nacional table with the nominal rate, as if that alone decided the company's fate. | Total cost compared: taxes, social security, accounting fees, other fees, the cost of switching and cash flow, with CNPJ continuity, contracts and risk in the same equation. |
| The CNAE code gets picked by the service's name, and nobody checks whether the real activity actually fits the MEI or which Simples Nacional annex it falls under. | Real activity before the code: what's actually delivered and to whom, which occupations the MEI allows, and the fator R deciding between Annex III and Annex V. |
| The answer mixes today's rule with tax reform changes that only kick in later, and nobody notices the difference. | What applies in 2026 stays separate from what changes starting in 2027, with a baseline date, an official source, and a list of what to confirm before acting. |
What you get out of it
A recommendation with the math shown, ready to bring straight to your accountant.
size, legal structure, tax regime and classification, laid out separately with every assumption flagged
fator R, annex and effective rate, with the formula, the time window, and what was left out
at least two lawful paths, compared by total cost and by risk
the recommendation, the backup option, the triggers to switch, and what to confirm
How it works
Baseline date, municipality, current status, real activity, revenue for the last 12 months, payroll, ISS, contracts and liabilities. Anything missing becomes a declared assumption.
A blown-through cap, a looming deadline, retroactive effects, a mismatched invoice, withholding or debt, all checked before any planning starts.
Deregister, convert into an LLC-equivalent while keeping the same CNPJ, close and reopen, Simples Nacional or presumed profit: at least two genuinely different routes.
Simulators for the MEI cap and for Simples Nacional on services, with the formula, the window and the source shown, plus a note on what the number leaves out.
The main path, the second-best option, the calculation trail, the risks, and what would change the decision.
Before you buy
No need to send passwords or full documents. Totals and facts are enough.
Its limits
The skill advises, simulates and recommends, but it is not a licensed accountant and doesn't perform any act reserved to one under Brazilian law. Filing returns, registration changes and bookkeeping stay with a qualified professional.
Taxes and obligations change, and municipal rules depend on the municipality. That's why every recommendation ships with a baseline date, an official source, and a checklist of what to confirm before acting.
The focus is Brazilian technology service providers under the MEI or Simples Nacional. Retail, manufacturing and complex corporate structures need their own separate analysis.

Before you ask
It's the ratio between payroll for the last 12 months, pro-labore included, and gross revenue over the same period. For activities subject to it, 28% or more lands you in Annex III, with a lower rate, and anything below that falls into Annex V. The skill runs the calculation with the formula and the time window shown.
It depends on the case, and that's exactly the question the skill organizes: the cap, allowed activity, payroll, ISS, contracts and the cost of switching. It compares deregistering, converting into an LLC-equivalent while keeping the same CNPJ, and closing to open a new company, then recommends based on total cost.
No. It prepares the decision with calculations, alternatives and sources, and flags what requires a licensed professional. Filing, bookkeeping and sign-off stay with your accountant.
Yes, keeping what applies in 2026 separate from what takes effect starting in 2027, so the current rule never gets mixed up with a future change.
It works as a starting point: exporting services, ISS and withholding are covered in the guides, always flagging what to confirm with your municipality and your accountant.
