The DNIT notifies your group through the Marandu tax mailbox. If you supply the State, also check RG DNIT 41/2025 (contracts under Law 7,021/2022). Texts and annexes: e-Kuatia resolutions, DNIT.

What changes on your start date

  1. Everything electronic. Invoices, credit and debit notes are valid only if they go through SIFEN. Sole exception: the virtual withholding receipt.
  2. Paper expires. Pre-printed or self-printed stamping lapses the next day. Before that, report the numbering used and cancel those stampings.
  3. Cancelling has a deadline. In e-Kuatia: 48 hours to cancel an invoice and 168 hours for other documents.

e-Kuatia or e-Kuatia'i? Answer 3 questions

1. How many establishments or issuing points do you have?
2. How many invoices do you issue per day?
3. Does the invoice start in an ERP, sales system or e-commerce?
Your pathe-Kuatia'i, the DNIT's free portalFew invoices and a single point: typing them in the portal is reasonable and needs no development.Example: 5 invoices a day × 3 min in the portal = 0.25 h a day of manual typing.

Frequently asked questions

Who must invoice electronically in Paraguay in 2026?

Taxpayers designated by the DNIT in groups 15 to 18 (General Resolution 21/2024) and 19 to 21 (General Resolution 52/2026), with start dates between March and December 2026. The DNIT notifies each taxpayer through the Marandu tax mailbox.

What happens on the day my obligation starts?

You must issue all tax documents exclusively in electronic format, with the sole exception of the virtual withholding receipt. The authorization and stamping of your pre-printed or self-printed documents expire the following day.

What is the difference between e-Kuatia and e-Kuatia'i?

e-Kuatia is the integration path: your own system (or a vendor's) generates the documents and submits them to SIFEN. e-Kuatia'i is the web platform run by the DNIT, designed for issuing without building your own software.

How do I get the electronic signature for invoicing?

For e-Kuatia integration you need a certificate from a Certification Service Provider accredited by the Ministry of Industry and Commerce. For e-Kuatia'i, the Qualified Electronic Signature Certificate is processed free of charge at DNIT tax offices.
