What is Tax & Revenue?
Tax & Revenue technology covers the digital systems that governments use to administer, collect, and manage taxes — from income tax and goods & services tax (GST) to property tax, customs duties, and tax compliance enforcement. India operates one of the world's largest tax technology platforms — GST Network (GSTN) processes 1B+ invoices per month, and the Income Tax e-filing portal serves 70M+ taxpayers. Tax technology involves complex domain logic (tax law codified as rules), massive-scale data processing, real-time validation, fraud detection, and seamless integration between government systems and taxpayer platforms. Understanding this domain teaches you large-scale government systems, rule engines, and financial compliance technology.
