Guatemala Tax Filing Guide 2026

Overview — Tax Filing in Guatemala

The Superintendencia de Administración Tributaria (SAT) operates a fully integrated online tax administration system. All tax filings, payments, and compliance are managed through the SAT portal (Declaraguate). Guatemala uses a self-assessment system where taxpayers calculate and report their own tax liabilities. The system covers ISR (income tax), IVA (VAT), and other taxes. The FEL (Facturación Electrónica en Línea) electronic invoicing system is mandatory for all registered taxpayers, transmitting invoice data to SAT in real time.

NIT — Número de Identificación Tributaria

All taxpayers must obtain a NIT (Número de Identificación Tributaria) from SAT. The NIT is a unique numeric identifier required for all tax transactions. To obtain a NIT, register on the SAT portal with valid identification (passport or DPI — Documento Personal de Identificación). A NIT is required for opening bank accounts, registering property, importing/exporting goods, obtaining business licences, and issuing invoices. Companies must have a NIT before they can operate legally in Guatemala.

Filing Deadlines

Different taxpayers have different filing deadlines in Guatemala:

• Monthly ISR provisional return — filed by the 10th of the following month (for businesses)
• Annual ISR return (individuals & companies) — filed by 31 March of the following year
• Monthly IVA return — filed by the 10th of the following month
• ISR withholding (employers) — monthly return by the 10th of the following month
• Property tax (IUSI) — payment to municipality by 31 March (annual) or quarterly

Late filing attracts penalties starting at 5% of the tax due, increasing to 25% plus interest at the legal rate for prolonged non-compliance.

Self-Assessment & Monthly Provisional Payments

Businesses and self-employed individuals must make monthly provisional ISR payments based on the previous year's tax liability or estimated current year profit. These monthly payments are credited against the final annual ISR liability calculated in the annual return. If monthly payments exceed the final liability, a refund may be claimed. If payments are insufficient, the balance is due at the time of filing the annual return. Underpayment of monthly instalments attracts interest.

SAT Online Portal (Declaraguate)

SAT's Declaraguate online portal allows taxpayers to:

• Register for NIT and tax types
• File monthly and annual returns
• Make tax payments (via bank transfer, credit card, or online payment)
• View tax history and compliance status
• Request tax clearance certificates
• Access FEL electronic invoicing system
• Track refund applications

Taxpayers can access the portal at www.sat.gob.gt. Registration requires a valid email address and DPI or passport number.

Penalties & Enforcement

SAT has broad enforcement powers under the Tax Code (Código Tributario). Key penalties include:

• Late filing — 5–25% of tax due plus interest at legal rate
• Late payment — interest at the legal rate per month
• Failure to issue FEL invoices — fines and potential suspension of operations
• Tax evasion — 100% penalty on the evaded tax plus criminal prosecution
• Failure to register for tax — fines plus back taxes

SAT may issue collection notices, seize bank accounts, or initiate legal proceedings for non-compliance.
