Monotributo Registration Certificate: where to get the official document
Choose what you need to do and we will identify the relevant official access. We do not generate a parallel certificate or ask for your Clave Fiscal.
Never enter your Clave Fiscal on this site. If authentication is required, we send you to the official portal.
The document
What it is and what it shows
The registration certificate provides official tax registration information for a taxpayer. ARCA notes that a Monotributo certificate may carry the wording “constancia de opción” because Monotributo is an optional alternative to the general regime.
It is not an Ingresos Brutos certificate. That document depends on the relevant provincial or city authority and may use a different public or authenticated service.
A generated Monotributo registration certificate is currently valid for 15 days according to ARCA. Return to the official portal for an updated copy when needed.
