We have professional legal and financial personnel to handle accounting and tax filing for our clients' Mexican companies. The tax filing process for Mexican companies is as follows: 1. Prepare tax return materials: Enterprises need to prepare VAT (IVA) calculation process forms, corporate income tax (ISR) calculation process forms and corporate unit tax (IETU) calculation process forms. In addition, they also need to provide data such as taxable profits, taxable income tax, net profits and profit distribution of taxpayers' employees. 2. Submit tax returns online: All tax returns must be submitted through the Federal Tax Administration (SAT) website. The return must reflect taxable profits, taxable income tax, net profits, and profit distribution to the taxpayer's employees. 3. Pay taxes: If the tax amount in the declaration form is inconsistent with the figure in the audit report issued by the independent auditor, the taxpayer needs to file a tax return according to the revised figure. After completing the tax return, the relevant accounting records need to be kept at the registered address for five years, and the accounting records need to be uploaded to the tax bureau website on a monthly basis. 4. Keep accounting records: After completing the tax declaration, taxpayers need to keep the relevant accounting records at the registered address for five years and upload the accounting records to the tax bureau website on a monthly basis. 5. Audit and review: If the tax bureau disagrees with the tax declared, it will conduct an audit and review. Taxpayers need to cooperate with the tax bureau's audit and review and provide necessary information and proof. It should be noted that Mexico's tax laws may change, so companies need to pay attention to the latest notices and announcements from the tax bureau to keep abreast of the latest tax filing requirements and procedures. At the same time, in order to avoid tax violations and fines, it is recommended that companies seek professional tax consulting and agency services to ensure compliance with tax filings.
