Overview
- The tax agency, which kept Thursday’s April 30 deadline in place, extended office hours to 9 a.m. to 6 p.m. through April 30, urged online filing, and pointed filers to SAT ID to recover passwords or e‑signatures.
- Automatic refunds only occur when you file the annual return, choose the refund option, and enter a working 18‑digit CLABE bank account in your own name.
- You must switch to the Electronic Refund Form if any exclusion applies, including a balance over 150,000 pesos, income in co‑ownership or marital community, a request for a year other than 2025, a prior manual request, skipping the refund option, or canceled digital certificates.
- The SAT has up to 40 business days to pay approved balances, though clean cases often post in 5 to 15 business days, and you can track progress in the online Tax Mailbox.
- Missing the deadline can bring fines, with media citing ranges from 1,400 to 17,370 pesos per duty not filed and 1,400 to 34,730 pesos for filing late.
