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.

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/

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

Tips

  • For Guatemalans with a valid DPI, the CUI already works as your NIT since March 2025
  • Names must match exactly with your DPI — any discrepancy will delay the process
  • If you don’t show up within 10 business days, you must file a new application
  • Foreigners must appear in person with their original passport
  • You can visit any SAT tax office nationwide
