General 2026 dates. Your tax regime, RFC and non-working days may change your deadline; check each obligation's official source.

Catalogue reviewed on 2026-09-26. Mexican federal taxes, social security and selected labour obligations for 2026.

Coverage and filters

Includes recurring deadlines, annual returns and special information returns. A taxpayer profile is a starting point: business, rental, employer and special-transaction obligations may coexist. Check applicability and exceptions in each entry.

Agenda covers the entire year. Month dots follow obligation filters. Select a day again to clear the date filter.

How deadlines are calculated

General dates combine the obligation's rule with weekends and published non-working days. Each entry distinguishes filing, payment, invoice issuance and labour obligations. Extra RFC days and individual extensions are not applied automatically. A Friday may extend payment at a bank; it does not move every Friday filing to Monday.

General SAT vacations do not automatically suspend returns and payments. Accounting submissions use published vacation periods. Dates after the review may change under later provisions.

RESICO, DIOT and electronic accounting

RESICO individuals and companies have relief from DIOT and electronic accounting submissions. Some individuals in other regimes may also qualify based on income. RESICO individual annual-return relief does not remove corporate annual returns or obligations on other income.

Obligations driven by your circumstances

Electronic signatures and digital seal certificates expire on their own dates. Worker registrations, terminations, salary changes, address or activity changes, notices and REPSE renewals depend on a specific event. They have no single national date applicable to everyone.

Review certificates, SAT and IMSS mailboxes and Employer Portal notices. Maintain a separate calendar for individually notified deadlines.

State, municipal and special-regime taxes

Payroll, lodging, property and other local taxes and incentives vary by state or municipality. This calendar does not assign them a federal deadline. Consult the finance authority where the tax arises.

Foreign trade, financial institutions, hydrocarbons, AML-regulated activities and sector-specific or half-yearly options need an additional calendar tailored to operations. Published coverage is not an assessment of all your obligations.

Editorial review and regulatory changes

Current statutes, the Official Gazette and authority publications take priority. Service pages may describe older years, so we also show legal provisions and conditions. SAT compilations help consultation; the Official Gazette remains the legal reference.

Review is editorial, not a real-time connection. These rules are not automatically extrapolated to 2027. Check amendments when your deadline depends on later relief or extensions.
