Argentina taxes resident individuals on worldwide income through the Impuesto a las Ganancias, administered by ARCA, the federal agency that replaced AFIP in October 2024. Employees whose only income is payroll compensation generally have the tax withheld at source and file no annual return; self-employed workers register and file every year.
Who counts as a tax resident in Argentina?
Argentine nationals, whether native or naturalised, are generally treated as residents. Foreign nationals become residents once they hold permanent residence or have stayed legally in the country for a qualifying period, after which worldwide income falls within the charge. Individuals who are not resident are taxed only on income sourced in Argentina, usually collected through withholding by the local payer rather than through a return.
Residents who leave Argentina to live abroad can lose resident status, which changes both what is taxable and how it is collected. Because the rules turn on immigration status, physical presence and intent together, dual-status years are common for people arriving or departing mid-year.
How is the Impuesto a las Ganancias structured?
The tax runs on a progressive scale of nine brackets, from 5% up to a top marginal rate of 35%. What moves is the income threshold at which each bracket begins: under Law 27.743, ARCA adjusts the bracket thresholds and the personal deductions twice a year, in January and July, against the consumer price index for the preceding six months. That semiannual indexation is a response to inflation, and it means figures quoted in any given month are superseded quickly. Current amounts are published by ARCA.
Three deductions do most of the work in reducing taxable employment income:
- Mínimo No Imponible — a basic personal allowance available to taxpayers generally.
- Deducción Especial — an additional deduction for employees and for self-employed workers, set as a multiple of the basic allowance.
- Cargas de Familia — allowances for a spouse and for dependent children who meet the conditions.
Do employees need to file an annual return?
Usually not. Where payroll compensation is a person's only income, the employer withholds the correct amount each month and that withholding settles the liability, so no return is filed for payment purposes. The obligation appears once there is a second income source — rental income, investment income, a professional practice on the side — or once the taxpayer is registered as self-employed. Employees in that position file an annual return and may also owe advance payments.
| Situation | Withholding | Annual return |
|---|---|---|
| Employee, payroll income only | Employer withholds monthly | Generally not required |
| Employee with other income | Employer withholds on salary | Required |
| Self-employed / professional | No employer withholding | Required, plus advances |
| Non-resident, Argentine-source income | Payer withholds at source | Generally not required |
How do self-employed workers register and pay?
Self-employed individuals register with ARCA, obtain a CUIT identification number, and file an annual return in the months following the close of the calendar year — the tax year matches the calendar year, and the specific due date within the May-to-June window depends on the taxpayer's CUIT. Balances due are paid at authorised banks after the return is filed, and advance payments toward the following year are calculated from the prior year's liability.
Smaller taxpayers may instead fall under Monotributo, a simplified regime that consolidates income tax, VAT and social security contributions into a single monthly payment, with the category determined by gross revenue and other indicators. Monotributo has its own thresholds and its own exit rules; moving between it and the general regime is a common source of confusion, particularly when revenue crosses a category ceiling mid-year.
What trips up new arrivals?
Two things, most often. The first is the semiannual indexation: a bracket table read in February no longer describes July. The second is the interaction between residence status and Argentina's treaty network, which determines which country has the first claim on a given item of income and whether relief is available for foreign tax already paid. Both are fact-specific, and both are worth confirming against current ARCA guidance rather than a secondary summary.
Where to get help
Individuals with Argentine filing obligations, and anyone moving into or out of residence during a tax year, can compare credentialed practitioners through the recognized professional bodies for Argentina. A registered contador público is the usual point of contact for ARCA registration, Monotributo categorisation and annual returns.
