Rinza AI is an Indian tax and finance platform designed to help individuals understand their income, identify potential tax deductions and prepare income tax returns. Its AI assistant offers guidance based on the Income Tax Act and the tax rules highlighted for FY 2026–27, including options such as HRA, Section 80C, Section 80D, NPS and capital gains exemptions. Users can track salary, business, rental and investment income, compare the old and new tax regimes, and get support selecting ITR-1 or ITR-2. The platform can generate an ITR-ready PDF summary for filing or record-keeping.

Rinza AI also provides a savings dashboard that estimates the tax impact of different actions, alongside comparisons of term and health insurance options. Its financial recommendations include curated credit cards and high-interest savings accounts for Indian earners. The service is presented as a way to manage tax and income information in one place, with free account registration and security features.
