ARCA Publishes April Monotributo Rates, Sets April 20 Due Date

The fixed monthly charge bundles tax, pension and health contributions into one amount tied to each category.

Overview

ARCA’s April schedule confirms the monotributo bill is due on April 20 for all CUITs, including the national regime and the unified system in Buenos Aires City.
Monthly amounts now run from $42,386.74 in Category A to $1,381,687.90 in Category K for services, with several tiers above $100,000.
The quota folds three parts into one payment: the integrated tax that replaces VAT and income tax, the SIPA pension contribution, and the obra social health contribution.
Category placement depends on billing caps that ARCA last updated in February 2026, ranging from $10,277,988.13 in Category A to $108,357,084.05 in Category K.
To enroll in a health plan through the regime, taxpayers choose an obra social in AFIP’s Monotributo portal, confirm the selection, make the first payment, and present ID and proof of payment to finish signup.
