The Tax Setup of a Mexican Subsidiary: From RFC to Your First VAT Refund
The registrations and monthly rhythm your entity enters the moment it exists — and how to design the setup so cash never gets trapped.
Registration is the doorway to everything
The RFC tax ID and the e.firma digital signature unlock invoicing, banking and permits. Obtaining them requires a legal representative registered in Mexico and an appointment with the tax authority — the practical bottleneck of most timelines. Book it as early as the incorporation itself.
The monthly rhythm
Mexican entities file monthly provisional income-tax payments and VAT returns, issue and receive CFDI electronic invoices for essentially everything, and keep electronic accounting in the authority’s formats. Miss the rhythm once and the tax mailbox fills with requirements; keep it and audits become paperwork instead of drama.
VAT: where cash gets trapped
A plant under construction pays 16% VAT on most inputs. Recovering it during the preoperative stage has a specific route, with elections to make and evidence to keep. Managed well, refunds help fund the launch; managed late, they become a year of trapped working capital.
Cross-border structure from day one
Transfer-pricing documentation for intercompany transactions, treaty positions on dividends, interest and royalties, and permanent-establishment discipline for the parent are design decisions at incorporation — not year-end afterthoughts. The cheapest tax planning is the kind done before the first invoice.
