Mexico:

In 2020, 2021 and 2022, the Company determined tax profits in its subsidiaries in the amounts of Ps.2,163,740, Ps.6,045,955 and Ps.9,997,669, respectively. In 2020, 2021 and 2022, the tax profits were partially offset with the amortization of tax losses in the amounts of Ps.3,196, Ps.192,040 and Ps.127,046, respectively.

The subsidiaries that at December 31, 2020, 2021 and 2022, have not assessed IT due to the tax loss carryforwards, are Cozumel, Minatitlán and Tapachula Airports.

Taxable income differs from the book income due to temporary and permanent differences arising from the different bases for the recognition of the effects of inflation for tax purposes and from the permanent effects of items affecting only the book or tax results.

The ITL establishes the applicable income tax rate of 30% on taxable income.

The Company has performed the evaluation of the Preferential Tax Regimes and has determined at December 31, 2021 and 2022, it is not applicable because it does carry out a business activity, in the case of the investment in the airport of Puerto Rico, and that passive income does not represent more than 20% of its total income.

Aerostar:

In 2020 the Company determined tax losses for Ps.660,404 and determined in 2021 and 2022 tax profit for Ps.88,577 and Ps.370,213, respectively, which partially compensated by amortization of tax losses for Ps.79,720 and Ps.333,191, respectively.
