Dominican Republic Tax Filing Guide 2026

All tax filing in the Dominican Republic is done electronically through the DGII (Dirección General de Impuestos Internos) online portal at dgii.gov.do. Businesses and individuals use the RNC (Registro Nacional del Contribuyente) as their tax identification number. Corporate ISR returns are due by March 31, individual returns by March 31, and ITBIS returns are monthly.

RNC Registration

The Registro Nacional del Contribuyente (RNC) is the tax identification number required for all taxpayers — individuals and businesses — who engage in taxable activities. Registration is done through the DGII portal. The RNC must be included on all invoices, contracts, and tax returns. For corporations, the RNC is obtained during the company incorporation process.

DGII Online Portal — E-Filing

The DGII provides a comprehensive e-filing system for all tax obligations:

  • Registration: Obtain and manage RNC, update taxpayer profile
  • Annual ISR return: File Formulario IR-1 (individuals) or IR-2 (corporations)
  • Monthly ITBIS return: File Form C612 by the 20th of each month
  • Withholding tax returns: File and remit WHT on dividends, interest, and royalties
  • Payment: Make tax payments electronically via approved banking channels
  • Certificates: Request residency certificates, tax clearance, and payment history

Authentication is done using a username and password (clave de acceso) obtained during RNC registration. Two-factor authentication is available for enhanced security.

  • Corporate ISR (CIT): March 31 of the following year
  • Individual ISR: March 31 of the following year

  • Incorrect filing: 10-25% of the underpaid tax, plus interest
