Income Tax Calculator: What It Is and Who Actually Pays It
Not everyone in Argentina pays income tax (Impuesto a las Ganancias). It only applies once your salary crosses a threshold set by AFIP each fiscal year. Below that threshold, you pay your standard contributions like retirement and obra social, but income tax doesn't enter the picture. Above it, the story changes.
Once your gross salary clears the non-taxable minimum, everything above that line gets taxed on a progressive scale. That means different portions of your income get taxed at different rates, not your entire salary at a single flat rate. The more you earn above the threshold, the higher the rate applied to that upper portion. The scale currently runs from 5% up to 35%, depending on your annual taxable income.
This calculator handles all of that math for you. You enter your gross salary, your personal situation, and any deductions that apply to you, and it tells you what your estimated income tax burden looks like for the 2026 to 2027 fiscal year, along with your effective rate and whether your current withholdings are on track.
How to Use the Calculator Above
The form has a few fields that are worth filling out carefully because each one directly changes your result.
Gross monthly salary: Enter your full pre-deduction figure, the one at the top of your payslip before anything gets taken out. This is the starting point for the entire calculation.
Annual payments (12 or 13): If you receive the annual complementary salary (aguinaldo), select 13. The aguinaldo is also subject to income tax withholdings, so including it gives you a more accurate annual picture. If you don't receive it, select 12.
Employment type: The calculation works differently depending on whether you're a registered employee, self-employed (autónomo), or a retiree. Each category has different deduction structures and withholding mechanics.
Dependent spouse and children: These matter because each dependent increases your allowable deductions, which reduces your taxable base, which lowers your estimated tax. If your spouse has their own income above a certain threshold, they don't count as a dependent.
Rent payments: If you rent your primary home, a percentage of what you paid annually is deductible. Enter your total annual rent and the calculator applies the corresponding deduction automatically.
Other deductions: Medical expenses, life insurance premiums, mortgage interest, and certain professional expenses may qualify. Add the annual total across all applicable deductions here.
Withholdings already made: If you're partway through the fiscal year and want to see your likely year-end balance, enter the amount your employer has already withheld. The calculator will estimate whether you're on track, underpaying, or heading toward a refund.
What a Taxable Base Actually Means
This is the concept that trips people up most often, so it's worth spelling out clearly.
You don't pay income tax on your entire gross salary. You pay it on your taxable base, which is what's left of your annual gross income after all legitimate deductions have been subtracted.
Here's a simplified version of how it flows:
Annual gross salary minus standard contributions (retirement, obra social, PAMI)
minus personal deductions (non-taxable minimum, special deduction)
minus family deductions (spouse, children)
minus specific deductions (rent, medical expenses, insurance)
equals your net taxable income
The progressive tax scale is then applied only to that final number. This is why someone earning a solid salary can end up with an effective tax rate of 10% or 12%, even though the top bracket sits at 35%. The deductions do a lot of work in reducing what actually gets taxed.
Withholdings on Your Payslip Are Not the Final Tax
Every month your employer deducts an estimated income tax amount from your salary. That's a withholding, not a final payment. Think of it as paying in installments throughout the year toward a tax bill that gets properly calculated once the year is over.
In April or May of the following year, your employer runs the annual adjustment. By then, they know your actual full-year income, every deduction you declared through the AFIP Siradig system (Form 572 Web), and the final tax figure for the year. If the monthly withholdings added up to more than you actually owed, you'll get the excess back as a balance in your favor, credited to your salary. If they fell short, you'll see an additional deduction.
This is exactly why keeping your Siradig up to date throughout the year matters. Every deduction you forget to load, or load late, means your employer is withholding more than necessary and you're effectively giving AFIP an interest-free loan until the annual adjustment corrects it.
Factors That Shift Your Tax Significantly
A few things that genuinely change how much you pay, beyond just your salary level:
Geographic location: Workers who live and work in Argentina's Patagonian region (Patagonia) have historically been entitled to higher deduction multipliers, which raises the threshold from which they start paying tax. If you're in that zone, make sure your employer has your registered address on file.
Non-remunerative bonuses: Certain payments employers make, sometimes agreed through union negotiations, carry a non-remunerative classification. These don't count toward your taxable income and can meaningfully reduce your annual taxable base during periods when they apply.
Year-end salary increases: If you get a raise late in the year, it can push your annual income projection above a higher bracket and result in a catch-up withholding in the remaining months. This is a common reason why November and December payslips sometimes show larger-than-usual deductions.
Updated scales: AFIP adjusts the brackets and the non-taxable minimum periodically to account for inflation. A salary that was below the taxable threshold last year may cross it this year with no actual raise, purely because of inflation adjustments lagging behind salary increases.

Effective Rate vs. Marginal Rate: The Difference That Actually Matters
Most people hear "I'm in the 35% bracket" and assume they're paying 35% on their salary. That's not how it works.
The marginal rate is the rate applied to the top slice of your income, the portion that falls in the highest bracket you reach. It does not apply to everything you earn.
The effective rate is the real number that matters. It's your total tax bill divided by your total gross income, expressed as a percentage. Because only the income above each bracket threshold gets taxed at that bracket's rate, your effective rate is always meaningfully lower than your marginal rate.
The calculator shows you both. The effective rate is the number to focus on when you're thinking about your overall tax burden or comparing your situation to others.
How Income Tax Connects to Your Net Salary
Standard payroll deductions, retirement, obra social, and PAMI, apply to everyone in formal employment. Income tax is a separate layer that only activates above the non-taxable threshold. When both apply simultaneously, the combined impact on take-home pay can be significant.
If you want to see how your full deduction picture comes together, the net salary calculator accounts for the standard 17% in mandatory contributions and lets you factor in income tax withholdings to see your real take-home figure. Running both calculators together gives you the clearest possible view of where your gross salary actually goes.
Who Needs to File a Tax Return in Argentina?
This one comes up often. Most employees in formal employment don't file an independent income tax return because their employer acts as the withholding agent and handles everything through the annual adjustment. Your role is to keep your Siradig updated with all your deductions.
However, you may need to file an individual tax return if you have income from multiple employers, significant additional income from rentals, investments, or self-employment, or if your total annual income exceeds the thresholds that trigger individual filing obligations. In those cases, consulting a certified public accountant is the right move rather than relying on employer withholdings alone.
Frequently Asked Questions
From what salary do you start paying income tax in Argentina in 2026?
The non-taxable minimum is updated periodically by AFIP through official resolutions. The threshold also changes depending on your employment category and whether you have dependents. The calculator above applies current 2026 projected figures, and you can cross-reference with AFIP's official publications for the most current official number.
Do I pay income tax on my aguinaldo?
Yes. The annual complementary salary is subject to income tax withholding. By selecting 13 payments in the calculator, it estimates the tax impact of your aguinaldo as part of the annual projection.
What's the AFIP Siradig and why does it matter?
Siradig (Form 572 Web) is the online system where you declare your personal deductions to your employer. Your employer can only consider the deductions you've formally declared there. Anything you forget to add doesn't get applied, and you end up with higher withholdings than necessary.
Can I deduct rent from income tax?
Yes, if you rent your primary residence and can provide documentation (a formal lease agreement), a percentage of the annual amount paid is deductible. The calculator applies the current allowable deduction rate automatically when you enter your rent figure.
What happens if I change jobs mid-year?
Your new employer starts withholding based on the salary they're paying you, but they may not have visibility into what your previous employer already withheld. It's important to notify your new employer of prior withholdings through Siradig so that the annual adjustment calculates correctly. Otherwise you risk a large year-end catch-up deduction.
Why is the calculator result different from my actual payslip deduction?
The calculator gives an annualized estimate based on your inputs. Your monthly payslip deduction can vary slightly because your employer adjusts each month based on actual payments made, deductions declared up to that point, and any updated AFIP tables. The annual total should align closely, even if individual months vary.
Does income tax apply to severance payments?
Generally, no. Severance compensation from dismissal without cause is exempt from income tax under Argentine law. But some components of a final settlement, like accumulated vacation pay or outstanding salary, may still be subject to regular withholding rules.
A Note on Using the Results
The figures this calculator produces are reliable estimates for planning and understanding purposes. They're based on projected 2026 to 2027 fiscal parameters and follow the standard calculation methodology.
They are not a substitute for professional accounting advice. If your situation involves multiple income sources, a significant rental portfolio, foreign income, or any complexity beyond a single formal employment relationship, a certified public accountant who knows Argentine tax law is worth every peso. Use this tool to understand your situation, ask better questions, and go into those conversations informed rather than in the dark.
