What is the annual tax return?

The easiest way to understand what the annual tax return is as the document with which

you report to a tax agency —in the case of Mexico, the Tax Administration Service (SAT) — your income, deductions, and withholdings, in order to to declare in a timely manner the Income Tax (ISR) applicable to a fiscal year.

In other words, it is the procedure that tells the Treasury how much money you received for your work or business activities and what percentage of that amount corresponds to contributing to the collection of taxes , in addition to how much will be returned or paid to you.

This tax burden is mandatory, as part of the responsibilities of taxpayers in Mexico —with some exceptions— and is legally supported by Article 31 of our Constitution, which says that an

obligation of Mexicans is:

Contribute to public expenses, as well as the Federation, as well as the States, Mexico City and

the Municipality in which they reside, in the proportional and equitable manner provided by law.

More specifically, the mechanism for collection, documentation and exemptions are

contemplated within the Income Tax Law , which I will use to impress you, but above all as a reference throughout this article.

Who does annual tax return?

The annual tax declaration is an obligation that must be carried out, both by

natural and legal persons , in order to report their income and fiscal situation for a specific year.

Although it is a mandatory process for all taxpayers, the law establishes who within these two types of people must declare, based on a series of criteria that we will see below.

To better understand the 2023 annual return for individuals , let’s review Article 150 of the Income Tax Law :

Individuals who earn income in a calendar year, with the exception of those who are exempt

and for whom final tax has been paid, are required to pay their annual tax by means of a

declaration that they will submit in April of the following year, before authorized offices.

However, the annual declaration for natural persons 2023  is relevant for those who

carry out business and professional activities for which they received income last year.

So, if you meet any of these criteria, you have to file an annual tax return:

• You carried out professional activities for a company that pays you a salary and the amount  of that income exceeds $400,000 MXN gross (before taxes) per year.
• You had income as a freelancer for fees.
• You received payment from two employers, even if the sum of everything does not exceed $400,000 MXN gross per year.
• You received income from labor compensation, liquidation, pension or retirement.
• You won the prize of a raffle, contest or raffle such as Pronósticos or the National Lottery  (and what envy, by the way).
• You receive interest on investments or financial funds that exceed $100,000 MXN gross per year.
• You received rent from a property.

Article 7 of the Income Tax Law identifies as legal persons —and therefore, they qualify to file an annual tax return—:

• commercial companies
• Decentralized organizations with business activities
• credit institutions
• Societies and civil associations
• Joint venture if you carry out business activities in Mexico
• cooperative societies
• Finance system
• Trusts with business activity

Also, I invite you to read our article that explains the difference between a natural person and a moral person , in case you want to review this point in detail.

When is the 2023 annual declaration made?

The period for individuals to make their 2023 annual declaration  in Mexico will be from April 1 to 30 . In the case of legal entities, their period to comply with this obligation is from March 1 to 31 . Write down in your diary when the 2023 annual declaration is made  so as not to forget it.

Remember that the declaration is always made the year after the end of the fiscal year or period —which corresponds to the calendar year that has just passed—, within periods and with processes established by the SAT.

So, the annual statement for one year corresponds to your income and deductions from the previous year. In other words, the 2023 annual statement  corresponds to the income you received during 2022.

• Paid statements: if you used capture lines to pay a balance against, in this part you review the status of those payments or statements from previous years.

• If you need to clarify more specific doubts, the SAT has some tutorials on YouTube to make your 2023 annual declaration,  such as this one dedicated to natural persons with wages, salaries and similar and interests:
• In case you need any document for access, visit SAT ID . There you can generate your password for the SAT site , renew your e.Firma , obtain your Evidence of tax situation with CIF and know the requirements for each of these procedures.

📢 Tip: do not despair if the portal pages take time to load or you cannot enter the site. Both the first days of the period to make the declaration and the last ones are the most saturated by users who want to use the system. Take advantage of a quiet morning or night during the weekend to carry out the process.

What happens if I have not declared in the Treasury?

Not making your annual tax return properly can have consequences that range from surcharges for not complying with the official deadlines and fines for non-compliance with the tax obligation, to the cancellation of the digital certificates linked to your RFC.

For example, according to article 82 of the Federal Tax Code , a fine of $15,860 to $31,740 MXN will be penalized for anyone who does not submit the returns in electronic media when they are obliged to do so, submits them after the deadline or does not comply. with the requirements of the tax authorities to present or comply with them outside the terms indicated therein.

In case of recurring faults, the SAT can determine the cancellation of your digital stamps, which would prevent you from invoicing both to sell and to collect, further complicating your situation.
