What the table does not show
The caps and what they mean
ARCA lists values from 1 August 2026. Maximum gross income per year runs from ARS$12,009,410.45 in category A to ARS$126,610,838.75 in category K. Your category also depends on floor area, electricity use and rent. These caps change with each update, so check the current table on the ARCA Monotributo page before you decide. Recategorization is done twice a year, in January and July.
When you are pushed out
ARCA says exclusion is automatic when your last 12 months of gross income pass category K, or when purchases plus costs reach 80% of that cap for goods sales or 40% for services. It also applies if you run more than 3 activities or units, import goods or services for resale, or your bank deposits do not match declared income. After exclusion you move to the general regime.
Why buyers care
A Responsable Inscripto issues invoices that let a business buyer claim IVA credit on its own return. A Monotributo invoice does not carry that credit. If your clients are companies that claim IVA, the general regime can win you sales even when your income fits Monotributo. Ask your accountant to model both before you register.
Where OCTIS fits
OCTIS does not do Argentine tax or bookkeeping. If you run a Malaysian or Hong Kong company with an Argentine freelancer, branch or subsidiary, OCTIS keeps the home books and can consolidate the statements your Argentine accountant provides. Ask about 10–30% off your current bill, and ask your local accountant which regime applies.
Frequently asked questions
Can a company use Monotributo?
No. ARCA states in its frequent questions that companies cannot adhere to Monotributo because the regime does not cover them. An SAS or SRL is registered under the general regime. Individuals who run or hold shares in a company may still use Monotributo for a separate small activity.
What is the IVA rate for a Responsable Inscripto?
The general rate is 21%, as shown in ARCA's IVA system tables. Other rates exist for specific goods and services, so check the current ARCA IVA page for your activity. Since November 2025 ARCA requires IVA returns through the IVA Simple procedure.
When do I have to recategorize?
Twice a year, in January and July, using your last 12 months of activity. Reports for July 2026 gave a window of 15 July to 5 August, but check the ARCA calendar for the current dates because they are set each period.
What happens if I go over category K?
You are excluded from Monotributo and must register under the general regime. The ARCA exclusion page lists the triggers. The cap for category K from 1 August 2026 is ARS$126,610,838.75 of gross income over the last 12 months.
Is Monotributo cheaper than Responsable Inscripto?
Usually at low income, since one payment covers IVA, income tax, pension and health cover. At higher income or with business clients the gap narrows, because IVA charged can be offset by IVA paid. Model both with an accountant using the current ARCA table.
