The RFC is the single administrative fact that decides how far a UGC career in Mexico can go. It is not a formality, it is the gate between informal work and the entire market of registered companies.
Why companies cannot hire you without it
A business needs a valid CFDI to deduct what it pays you. No RFC means no CFDI, which means the payment is not deductible, which means their finance department will simply refuse. This is not negotiable and no amount of good work changes it.
What registration actually involves
Registering as a person with professional activity, obtaining the RFC and the electronic signature, and choosing a tax regime. Most creators fall under the simplified confidence regime, which is designed for exactly this kind of individual income and keeps the monthly obligations light.
What the invoice must carry
The client's tax details, a clear description of the service, the amount, the applicable VAT and the withholding. Get these right on the first invoice, because a rejected CFDI usually means the payment cycle restarts and you wait another two weeks.
Withholding changes what you receive
Companies withhold a portion of income tax and VAT on payments to individuals. That amount is not lost, it counts against what you owe, but it does mean the money in your account is smaller than the figure on the invoice. Quote knowing that.
Doing it before you need it
Register before the first company client rather than during the negotiation. Nothing kills a first contract faster than telling a brand you will need three weeks to sort out your tax status before you can invoice them.
