- SAT Portal — public lookups (NIT, RTU, fiscal calendar) without login
- Agencia Virtual — your account: RTU, FEL invoices, NIT card, tax history (NIT + password)
- Declaraguate — for paying taxes only: IVA, ISR, ISO, fines, late interest
SAT (Superintendencia de Administración Tributaria) is Guatemala’s tax authority — equivalent to the US IRS. It runs all national taxes (IVA/VAT 12%, ISR income tax, ISO solidarity tax, import duties) and the FEL electronic invoicing system. To do anything tax-related (get a NIT, file IVA, pay taxes, issue FEL invoices, register a vehicle, import goods) you use one of the three official portals above.
Quick rule: Looking up something public? → SAT Portal. Paying a tax? → Declaraguate. Doing anything else with your account? → Agencia Virtual.

| Scanned DPI / passport | For initial registration and password recovery |
| Active email | SAT sends confirmations, boletas, reminders |
| Guatemalan bank account | For paying boletas online (Banrural, Industrial, BAC, BAM, G&T) |
| Updated browser | Chrome or Firefox work better than Safari/Edge on SAT |
SAT 2026 fiscal calendar — key dates
| Obligation | Due | Who |
|---|---|---|
| Monthly IVA | 15th of following month | All RTU registrants with activity |
| Monthly ISR | 10th of following month | Optional / Profit regimes |
| Annual ISR | March 31 of following year | All registrants |

Diaspora tip: If you live abroad with active SAT obligations, add the 14th-15th to your monthly calendar. SAT servers crash that day — file earlier (days 5-10) to avoid issues.
Diaspora — using SAT from the United States
If you live abroad and need to keep your RTU active:
| Need | How to do it from the US |
|---|---|
| Keep NIT active | Agencia Virtual works from any country. No need to close the RTU. |
| Pay taxes | Generate boleta in Declaraguate, pay via Guatemalan bank app, or have family pay in person |
| Issue FEL invoices | Agencia Virtual works abroad — useful if you still bill professional services in Guatemala |
| Get Fiscal Solvency | Agencia Virtual / consulate — required for property sales or notary acts in GT |
| Digital NIT card | Download from Agencia Virtual to your phone — replaces physical card |
| Close RTU | If you no longer want to maintain obligations, request closure — in person or via accountant |

What NOT to do on the SAT portal
- Don’t use third-party apps claiming to be SAT — SAT has no official app, all are fraudulent
- Don’t wait until the last day — servers crash on the 14th-15th and March 31
- Don’t share your SAT password — not even with accountants until you sign formal authorization
- Don’t use VPN when paying — some banks block VPN connections for security
- Don’t ignore SAT emails — fines and interest accumulate automatically
