Your Mexican Company's Tax Compliance — In English, From Anywhere
Own a company in Mexico but live abroad? iAudita connects directly to the SAT (Mexico's tax authority) and shows you — in plain English — whether your invoices, filings, payments and compliance are actually in order. Because in 2026, a supplier you never met or a filing your accountant skipped can freeze your ability to invoice.

The rules just got stricter — and the risk moved to the owner
Mexico's 2026 tax reform and the SAT's enforcement plan changed what's at stake. Three shifts hit foreign owners hardest:
Buyers are now on the hook
Under the 2026 reform, the company that deducts a fake invoice — not just the one that issued it — can face criminal exposure, and the SAT can suspend your digital seal (CSD) so you can't issue invoices at all. (Arts. 49 Bis & 113 Bis, CFF)
A valid invoice is no longer enough
The SAT now routinely asks you to prove operations were real ("materialidad"). Without that proof, deductions can be reversed up to 5 years back, with fines — for companies of any size. (KPMG · Bloomberg Tax)
The SAT audits with AI
It cross-checks your invoices with analytics and can flag you through your suppliers' networks. Fewer audits doesn't mean lower risk. (SAT Master Plan 2026)
Running a Mexican company from abroad means trusting what you can't see
The SAT can audit up to 5 years back, cross-checks every invoice with analytics, and publishes a public blacklist of fake-invoice issuers. If you don't read Spanish or aren't logging in to the SAT, you're trusting that nothing slips through.
Silent SAT notices
The SAT's tax mailbox (Buzón Tributario) is Spanish-only and treats you as legally notified even if you never open the message. Audit and cure deadlines can run out against you without you ever seeing them.
Fake-invoice (EFOS) exposure
If a supplier lands on the SAT's Art. 69-B blacklist, the deductions you took from them are at risk — and now the exposure reaches you as the buyer. You can't easily vet a supplier your local accountant paid.
No independent oversight
You rely entirely on one local accountant, with no real-time way to confirm filings were submitted and taxes were paid. A second, automated set of eyes protects you — and them.
One dashboard for your company's entire SAT footprint
iAudita connects to the SAT with your company's credentials and keeps everything in sync — automatically, every day. Mexican tax terms are explained in plain English below.
Invoice download & validation (CFDI)
Every invoice your company issues and receives, pulled straight from the SAT and validated. The invoice — the "CFDI" — is the document that gates every deduction, so we confirm yours actually exist and are valid.
Daily EFOS blacklist screening
Every supplier checked against the SAT's fake-invoice blacklist (Art. 69-B), every day. The moment one is flagged, you know — before your deductions are at risk.
Filings & payments oversight
Mexican companies must file and pay taxes every month (income tax/ISR, VAT/IVA) plus an annual return — that's "declaraciones y pagos". See on one screen whether your accountant actually filed and paid, before missed filings let the SAT restrict your invoicing.
Live Compliance Opinion (32-D)
The "Opinión de Cumplimiento" is the SAT's official certificate that your company is current on its taxes. It can flip the moment a filing or payment is missed — iAudita re-checks it continuously and alerts you the second it turns negative.
Tax mailbox (Buzón) alerts
The SAT notifies companies through an official electronic mailbox — and you're considered legally notified even if you never open it. iAudita watches it and alerts you in English, so a silent notice never runs a deadline against you.
Financial intelligence
Cash flow, net profit, VAT and income-tax projections — your numbers, explained in English, without waiting for month-end. Own several Mexican entities? Monitor them all from one consolidated view.

Your fiscal data is protected at every layer
Tax credentials are some of the most sensitive data you own. We treat them that way.
- Zero-knowledge access. Your password is encrypted in your browser before it ever leaves your device — not even our administrators can recover it.
- Isolated e.signature vault. Your FIEL is encrypted (AES-256-GCM + RSA-OAEP) and kept in a vault on an internal network with no route to the internet.
- Per-company isolation. Row-Level Security at the database keeps each company's data invisible to every other.
- Separated engines. iAudita runs across isolated servers — compromising one area never exposes the others.
