- 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.

| 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 |

Diaspora tip: If you live abroad with active SAT obligations, put the deadlines above in your calendar and file early in the window rather than on the last day.
Notifications on your phone: the official SAT GT app has a notification settings menu (Configuración de notificaciones) where you choose which notifications you want to receive and how many days in advance you want them, according to SAT’s own SAT GT listing on Google Play.
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’s official app is SAT GT, published under SAT’s own name
- Don’t wait until the last day of a filing window, or until March 31 for the annual ISR return
- 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
