- 📄 Your NIT (always needed to identify yourself)
- 👤 SAT username + password (same as Agencia Virtual — for formal returns)
- 💵 Amount to declare/pay (work it out beforehand in Agencia Virtual or have the calculation ready)
- 🏦 Guatemalan bank account (Banrural / Industrial / BAC / BAM / G&T) or a printed slip to take to the bank
- 📅 Due date in mind (automatic late-payment interest if you pay late)
Declaraguate (declaraguate.sat.gob.gt) is SAT’s official portal specifically for declaring and paying taxes. It is where you generate SAT payment slips (Boletas SAT) that you then pay via bank — monthly VAT, income tax, ISO, IETAAP, penalties, late-payment interest, and other taxes.
Quick summary: Declaraguate is for generating payment slips. Agencia Virtual SAT is for everything else (RTU, FEL, certificates, profile). Since September 1, 2026, General Regime taxpayers file the monthly VAT return (SAT-2237) and the ISR and ISO returns in Agencia Virtual only; Declaraguate stays for Pequeno Contribuyente and the special primary and agricultural regimes, and for many other SAT forms.

How to generate and pay a slip (step by step)
Step 1 — Identification
- Go to declaraguate.sat.gob.gt
- Enter your NIT (if your procedure does not require login) or username + password (if it is a formal return)
- Confirm your identity if it requests a verification code
Step 2 — Select the procedure
- Menu “Trámites Disponibles” → choose the tax (e.g. VAT, monthly income tax)
- Confirm the tax period (month/year)
- If you already filed the return in Agencia Virtual, the data is pre-loaded
Step 3 — Generate the slip
- Verify the amount to pay
- Generate the SAT slip (complete form with a unique number)
- Download the PDF — the slip has a reference number, amount, and due date
Step 4 — Pay
Option A — Online payment (fastest):
- From your bank’s app (Banrural, Industrial, BAC, BAM, G&T)
- “Payments” section → “SAT” → enter the slip number + amount
- Confirm → receipt saved in your app
Option B — In-person payment at a bank:
- Take the printed slip to any branch of a bank with SAT integration
- The teller processes it and gives you a stamped receipt
- Keep the stamp as proof
Option C — Through Agencia Virtual SAT (linked account):
- If you linked a bank account to Agencia Virtual
- You pay directly from the SAT portal, with an automatic receipt
Critical deadlines
| Procedure | Due date | If you pay late |
|---|---|---|
| Monthly VAT | Within the following calendar month (Ley del IVA art. 40) | Penalty + interest |
| Monthly income tax (Optional Simplified) | First 10 days of the following month (art. 49) | Penalty + interest |
| Annual income tax | First three months of the following year, so by March 31 (art. 39) | Significant penalty (% on the undeclared amount) |
| Quarterly ISO | Month following the quarter close | Penalty + interest |
Tip: SAT calculates late-payment interest automatically — if you pay late, the next time you enter the system you will see the debt updated with the surcharges.
What to do if the site goes down near a deadline
SAT servers get busy close to filing deadlines — the end of the month for VAT and Pequeno Contribuyente returns, and March 31 for the annual income tax return. Recommendations:
- NEVER wait until the last day — file early in the window
- If you are up against the deadline: try “odd” hours (4-6 AM, 10-11 PM have less traffic)
- Generate the slip and pay at a physical bank if the portal will not load
- Call 1550 to report a system outage — SAT sometimes extends the deadline if it confirms a nationwide failure
For the diaspora — paying SAT from the US
If you live in the US and need to keep SAT obligations active:
| Strategy | How it works |
|---|---|
| Active GT bank account | You pay directly from your Guatemalan banking app using the SAT slip number generated |
| Ask family in GT | You generate the slip in Declaraguate, send the PDF to family, they pay at a bank. They send you the receipt by WhatsApp. |
| Via an accountant | If you have an accountant in GT, you give them access or send them slips. They charge Q200-500/month for basic maintenance of obligations |
| Wise for funding | If you need to fund a GT account from the US, Wise is the cheapest option (real market rate). See our remittance comparison |
What NOT to do
- Do not use unofficial apps that claim to pay SAT for you — fraud risk
- Do not wait until the last day — the servers crash
- Do not ignore overdue slips — interest grows automatically and SAT can garnish accounts
- Do not use a VPN when paying — some bank integrations block VPN connections for security
Support line
- SAT 1550 (from Guatemala) / +502 2329-7070 (international)
- Monday to Friday 8 AM - 6 PM
- For problems with specific slips, mention the reference number
