Integrated Tax Administration System (ITAS)

Integrated Tax Administration System (ITAS)

Modern Revenue Administration for Government

FreeBalance Integrated Tax Administration System (ITAS) is a modern, modular solution that covers the full revenue lifecycle — from taxpayer registration through filing, payments, compliance, audit and collections. Built on international best practices and natively integrated with FreeBalance’s Government Resource Planning (GRP) platform, ITAS gives governments a configurable, digital-first alternative to aging legacy tax systems.

ITAS is purpose-built for central-government revenue authorities administering domestic taxes end-to-end, and integrates with Gestión de ingresos públicos and GFMIS for non-tax revenue, receipting and wider public financial management.
