Enter your RUC and see every filing and payment date for the next twelve months — VAT, income tax and its advances, dividends, withholdings, social security and the annual registers — then add them to your calendar.
Dates falling on a weekend or a fixed national holiday move to the next business day. DNIT occasionally extends deadlines by resolution; its own calendar prevails.
One digit decides the day
The last digit of the RUC before the hyphen: 0 files on the 7th, 1 on the 9th, rising by two to 9 on the 25th. Informative returns fall one day later.
VAT is monthly, even with no sales
Form 120 for the previous month, filed and paid on your RUC day. Invoices are registered in Marangatu under RG 90/2021.
Income tax is annual, with four advances
IRE General is due in the fourth month after year end, with advances in the 1st, 3rd, 5th and 7th months after. IRE SIMPLE is due in the third month.
Some dates are fixed for everyone
Withholdings via Tesaka by the 7th; dividend tax (IDU) by the 13th of the month after payment; beneficial owners by 30 June.
Law and practice: calendario perpetuo under RG 01/2007 and RG 38/2020 (DNIT confirmed it remains in force, 2025); IDU dates per DNIT notices 2026; IPS payment days by employer zone per IPS Resolución C.A. 090-024/2008; beneficial owners under Ley Nº 6446/2019. DNIT extended the 2025 financial-statements deadline to June 2026 (RG 50/2026) — one-off extensions like this are not reflected. Rules as of October 2026; general information, not advice.
