If you are operating or planning to expand into Mexico, understanding the corporate tax rate in Mexico and how it is applied is non‑negotiable for budgeting, compliance, and board reporting. The rules are detailed, the Mexican tax authority (SAT) is data‑driven, and mistakes can quickly turn into penalties or audit triggers.
This guide explains how corporation tax in Mexico works in practice for resident and non‑resident companies, from income tax and VAT to payroll and withholding obligations. You will also see the main corporate tax filing in Mexico, payment deadlines, incentives, and where Commenda fits into a modern compliance stack.
What Is the Corporate Tax Rate in Mexico?
So, what is the corporate tax rate in Mexico right now for standard companies? The general corporate income tax rate in Mexico is 30% on taxable profits for resident legal entities known as personas morales.
This 30% corporate tax rate in Mexico also acts as the benchmark rate for many incentive calculations and safe‑harbor rules, while non‑resident companies pay Mexican tax mainly through withholding on Mexican‑source income.
Breakdown of Corporate Income Tax Components
When you look beyond the headline corporate tax rate in Mexico, you see a stack of federal, state, and local obligations that all affect your effective tax burden. You will typically face federal ISR on profits, monthly VAT, state payroll contributions, social security, and municipal property tax if you hold real estate.
| Component | Key details | Impact on business |
| Federal corporate income tax (ISR) | Flat 30% on taxable profit for companies, based on accounting profit adjusted under the Income Tax Law. | The main driver of corporation tax in Mexico directly affects net margins and group’s effective tax rate. |
| Monthly provisional ISR payments | Legal entities must calculate and pay monthly advances, generally by the 17th day of the following month. | Spreads cash flow impact across the year and requires reliable monthly management reporting. |
| Value-Added Tax (IVA) | Standard 16% rate on most goods and services, with 0% and exemptions for specific items. | Does not change the corporate income tax rate in Mexico but shapes pricing, cash flow, and input credit management. |
| State payroll tax | State‑level tax on total payroll is usually between 1 and 3%, depending on the state. | Adds a labor‑cost surcharge and influences where you choose to hire staff inside Mexico. |
| Social security and housing | IMSS (social security) payroll contributions typically range from 24% to over 38% of salaries, plus a mandatory 5% contribution to INFONAVIT housing | Significant part of total employment cost, separate from corporate tax rate but essential for budgeting. |
| Municipal property tax (predial) | Annual municipal tax on real estate, commonly around 0.05% to 0.3% of cadastral value, with local variations. | Recurrent cost for asset‑heavy businesses and those owning offices, warehouses, or industrial facilities. |
Together, these items form the corporate tax system in Mexico that you need to model when you forecast effective tax rates and cash outflows.
Corporate Tax Filing Requirements in Mexico
Corporate tax filing in Mexico centers on electronic interaction with SAT using your company’s RFC and e‑firma digital signature, supported by CFDI e‑invoices for revenue and expenses. You must comply with both monthly and annual ISR obligations, plus VAT, payroll, and information returns where thresholds apply.
Annual corporate income tax return
- File the annual ISR return for personas morales by March 31 following the end of the calendar tax year.
- Submit through SAT’s “Declaraciones y Pagos” online service, using official forms for your specific regime.
- Attach financial statements, reconciliation between accounting and taxable income, and details of credits or loss carryforwards.
Monthly returns and payments
- Make monthly provisional ISR payments and file the ISR declaration by the 17th day of the following month.
- File VAT returns monthly, usually by the 17th, and pay any net IVA due after offsetting input credits.
- Report payroll withholdings and employer social security contributions on regular monthly or bi‑monthly schedules set by IMSS and INFONAVIT.
Documentation, platforms, and penalties
- Keep complete CFDI invoices for income and deductible expenses, plus supporting contracts, payroll records, and bank documentation.
- Use SAT’s online portal and authorized banks or payment channels to settle taxes in pesos from Mexican accounts.
- Late filing or payment can trigger SAT fines in the thousands of pesos per return, along with surcharges and possible audit exposure.
A specialist partner or platform like Commenda can centralize these workflows so that company tax filing in Mexico requirements stay synchronized across corporate income tax, VAT, and payroll.
Tax Year and Payment Deadlines in Mexico
Most companies in Mexico are taxed on a calendar‑year basis for ISR, meaning your tax year runs from January 1 to December 31. The combination of monthly provisional ISR, monthly VAT returns, and the March 31 annual deadline creates a concentrated compliance period for finance teams.
- Corporate annual ISR return for the prior year is due by March 31 and filed electronically.
- Monthly ISR provisional payments must be made by the 17th day of the following month, based on the prior‑year profit coefficient.
- Monthly VAT returns and payments are generally due by the 17th as well, with definitive IVA calculated on net taxable operations.
- State payroll tax and social security contributions follow monthly or bi‑monthly schedules that often mirror these dates.
Building a compliance calendar that combines corporate tax payment deadlines in Mexico with VAT, payroll, and treaty reporting requirements is essential to avoid penalties and interest.
Withholding Taxes and Other Business Taxes in Mexico
If your group receives or pays cross‑border income tied to Mexico, withholding taxes sit alongside the corporate income tax rate in Mexico as a key planning item. Dividends, interest, royalties, and capital gains can all face final Mexican withholding for non‑residents, subject to relief under tax treaties.
| Income type | Typical domestic WHT rate | Notes for businesses |
| Dividends to non‑residents | 10% on dividends paid from profits generated from 2014 onward. | Mexican companies must maintain CUFIN accounts and withhold when distributing to foreign shareholders. |
| Interest | Roughly 4.9 to 35%, depending on the type of interest and the recipient, with higher rates for related parties. | Beneficial owner tests and treaty provisions can reduce rates for banks, institutional investors, and some bondholders. |
| Royalties and technical assistance | Commonly, 5% to 25% on gross payments to foreign recipients. | The exact rate depends on the payment classification and any applicable DTT cap. |
| Capital gains on shares or real estate | 25% on gross proceeds or 35% on net gain in many cases. | Foreign sellers of Mexican real estate or significant shareholdings often settle through a Mexican notary or tax representative. |
| VAT | Standard VAT applies at 16% on most supplies, with a 0% rate available for exports and certain qualifying goods and services. | VAT is generally not a cost if you can recover input tax, but poor documentation can block credits. |
Understanding these rules is crucial when you decide how to finance Mexican operations, price intragroup royalties, or structure exits involving Mexican assets.
Corporate Tax Incentives, Deductions, and Exemptions
Despite the headline 30% corporate tax rate in Mexico, there are useful incentives and deduction tools that can reduce your effective rate when used correctly. These range from R&D credits and accelerated depreciation to special zones and sector‑specific programs.
- A federal R&D incentive offers a 30% tax credit on incremental qualifying R&D expenditure above the prior three‑year average.
- The decree grants a tax credit equivalent to a third of income tax calculated by taxpayers in the region (reducing income tax to 20%).
- Plan Mexico allows accelerated depreciation of new fixed assets acquired from January 22, 2025, through September 30, 2030.
These corporate tax incentives in Mexico require advance registration, ongoing eligibility checks, and careful interaction with transfer pricing and safe‑harbor rules, so they are best handled with dedicated advisory support.
International Tax Treaties and Double Taxation Avoidance
Mexico has a broad network of treaties that interact with its corporate tax system to prevent double taxation and reduce withholding on cross‑border payments. This network now covers more than 60 jurisdictions, including the United States, Canada, major EU countries, and several partners in Latin America and Asia.
- SAT publishes detailed treaty texts and status tables showing which treaties are in force and the reduced rates for dividends, interest, and royalties.
- Under most treaties, you can credit Mexican tax against home‑country tax or apply reduced Mexican withholding if residency and beneficial ownership tests are met.
- Some treaties provide specific rules on permanent establishments, capital gains, and technical services that override domestic rules when certain conditions are met.
- Mexico has also signed the OECD Multilateral Instrument, which can modify treaty provisions on hybrid mismatches and treaty abuse.
To avoid being taxed twice on the same income, you usually need a valid certificate of residence and proper documentation before the Mexican payer applies treaty‑reduced rates at source.
