¿Buscas consultar tu CUI-NIT en línea? Esta guía está en inglés y cubre el registro de NIT (extranjeros y empresas). Para la consulta gratuita CUINIT del portal SAT en español, visita Consulta CUINIT 2026 (SAT).

The NIT (Numero de Identificacion Tributaria) is Guatemala’s taxpayer identification number, issued by the SAT (Superintendencia de Administracion Tributaria). You need it for any economic activity in Guatemala — from opening a bank account to starting a business.

Quick summary: The NIT is free (Q0). Since March 2025, your DPI number (CUI) automatically works as your NIT if you’re a Guatemalan citizen. Foreigners must apply in person at SAT with a valid passport.

This page is for: foreigners getting their first NIT, business/entity NIT registration, and US-based diaspora handling NIT processes from abroad. If you’re a Guatemalan citizen looking up your existing CUI-NIT number, use the SAT CUINIT consulta page → (or in Spanish →).

Cost

Free (Q0) — There is no official fee.

What Changed in 2025

Through Resolution SAT-DSI-393-2025, the CUI (your DPI number) was unified with the NIT for individual Guatemalan citizens. Your 13-digit DPI number is now your NIT — no separate registration needed.

You can verify the unification at: portal.sat.gob.gt/portal/consulta-cui-nit/

Details

If you run a foreign company that sells into Guatemala but has no physical office, you may still need a NIT for customs, tax withholding, or contract purposes. In this case, you must appoint a legal representative in Guatemala who applies for the NIT on behalf of the foreign entity. This requires: a power of attorney from the foreign company (apostilled), articles of incorporation of the foreign entity (translated and apostilled), and the legal representative’s DPI. The process is more complex than a standard NIT and may require legal assistance from a Guatemalan attorney.

Details

If your DPI is expired or in the process of being renewed at RENAP, SAT may refuse to process your NIT registration because they require a valid (non-expired) DPI. You cannot use a temporary RENAP receipt in place of a valid DPI for NIT purposes. Solution: renew your DPI first, wait for the new card, then proceed with the NIT process. If you already have a NIT and your DPI expires, your NIT remains valid — you just cannot make changes to your RTU until you present a current DPI.

Details

If there is a discrepancy between your DPI name and your NIT records (common after name changes due to marriage, or after DPI renewals that corrected spelling), you must visit a SAT office in person to update your NIT records. Bring your current DPI (with the correct name) and any supporting legal documents (marriage certificate, court order for name correction). SAT will update the NIT record to match the DPI. Do not attempt to file declarations or request a solvencia fiscal until the name mismatch is resolved — SAT’s system may flag inconsistencies.

From the US (Diaspora Info)

If you’re a Guatemalan citizen living in the United States:

  • Your DPI number already is your NIT since March 2025 — verify at portal.sat.gob.gt/portal/consulta-cui-nit/
  • If you need to register a new NIT (for a business, etc.), you must do it in person in Guatemala
  • Power of attorney option: You can authorize someone in Guatemala through a poder especial notarized at a Guatemalan consulate to handle the process on your behalf
  • Nearest consulates: minex.gob.gt/consulados — offices in Los Angeles, New York, Houston, Chicago, Washington DC, and other US cities
  • Call the SAT information line: 1550 for questions
