In general, the taxable income in the income tax for resident entities and resident individuals is equal to gross earnings minus deductions. In general, all expenses incurred to obtain, maintain and preserve taxable income are deductible unless expressly forbidden.
Non-resident entities and individuals are taxed on income of Argentine source by way of income tax. The local resident paying to a foreign entity or individual is obliged to withhold the income tax at a 35-percent (or 15-percent for some gains as capital gains) tax rate applied on a presumption of taxable income that varies in connection with the concept by which the payment is made. The presumption of taxable income can be from 35 percent up to 100 percent of the amounts paid.
For incomes connected to the transfer of shares, bonds or titles, or incomes connected with the rental of real estate or the transfer of assets located in Argentina owned by a non-resident, the non-resident individual or entity is entitled to choose to apply the presumption of income or to present evidence of all the expenses incurred and deduct those expenses from the gross amount to be paid.
