ANNUAL TAX RETURNS FOR INDIVIDUALS 2021

Dear clients and friends:

          The objective of this bulletin is to provide you with general information regarding compliance with some of the tax obligations that individuals have in Mexico, for the 2021 fiscal year.

          As everyone knows, in accordance with the Income Tax Law (hereinafter “LISR”), individuals who are residents for tax purposes in this country and who obtain income are required to pay income tax in Mexico, among others, in cash, in goods, in credit, in services, or of any other type, obtained either in Mexico or abroad.

          On the other hand, in accordance with Article 150 of the LISR, individuals who obtain income (except exempt income and on which a definitive withholding has been made) in a calendar year are required to pay annual income tax by means of a declaration that must be presented no later than April 30th  of the year following that in which the aforementioned income was obtained. In the case of the 2021 fiscal year, the deadline would be April 30th, 2022, however, since it is a non-business day, the annual tax return may be submitted no later than Monday, May 2nd, 2022, based on the Federal fiscal Code.

          On the other hand, it should be noted that individuals who only obtain accruable income from salaries and in general from the provision of a subordinate personal service (Chapter I, Title IV of the LISR) and interest may choose not to file an annual return (Chapter VI, Title IV of the LISR), when the sum of both does not exceed $400,000, provided that the actual interest does not exceed $100,000, and the withholding referred to in the first paragraph of Article 135 of this Law has been applied to the income

          Likewise, the LISR establishes that taxpayers who have obtained total income in excess of $500,000 in the fiscal year being declared (including those for whom they are not required to pay income tax and for whom the definitive tax has been paid), must declare all their income received, including those for which they are not required to pay income tax, such as travel expenses incurred in service of the employer, the sale of a home (for the exempt part) and those received by inheritance or legacy.

          As far as employees are concerned, also an annual tax return must be submitted in the following cases:

  • When they obtain accruable income other than wages and interest.
  • When they have had informed in writing to the withholder that an annual tax return will be filed.
  • When they provide services to two or more employers simultaneously.
  • Yes, they also obtained compensation or retirement income.
  • When the provision of the service has begun after January 1 or ceased to be provided before December 1 of the year in question, and the sum of $400,000 is exceeded for this concept.
  • When they have obtained salary income from a source of wealth located abroad or from persons not required to make the withholdings.

          Individuals must file an annual tax return, among other cases, when they have obtained income in the year from:

  • Business and professional activities.
  • Business activities, including those who are taxed under the Tax Incorporation Regime and opted to make bimonthly provisional payments applying the profit coefficient.
  • Business activities carried out only through technological platforms, computer applications or similar, which have not chosen to make final payments.

          Individuals even if they are registered in the Tax Incorporation Regime (RIF) and have not opted to make bimonthly payments applying the profit coefficient, they do not file an annual return, since said regime the bimonthly returns that are filed during the year are considered definitive.

Personal deductions:

          In accordance with Article 151 of the LISR, individuals may deduct, in addition to the deductions authorized for each of the Chapters of Title IV (corresponding to each type of income), the following concepts:

  • You can deduct complementary retirement contributions and voluntary contributions made directly to your subaccount, as long as they meet the permanence requirements. Contributions that will be used exclusively for use when the holder reaches the age of 65 or in cases of disability or inability to perform paid personal work in accordance with social security laws are deductible.
  • Insurance premiums for medical expenses, complementary or independent of health services provided by public social security institutions, provided that the beneficiary is the taxpayer himself, his spouse or the person with whom he lives in concubinage, or his ascendants or descendants, in a straight line.
