# Welcome to Caesar Caesar is a crypto tax rail that turns crypto transaction data into tax-ready outputs. Built as API-first infrastructure with a rules-as-data architecture that handles crypto tax calculations so you don't have to. If you run a crypto platform (an exchange, wallet, payment gateway, or trading app), Caesar takes care of the complicated tax stuff for both you and your users. **What Caesar does for you:** * ✅ Calculates capital gains when users sell crypto * ✅ Tracks income tax on crypto rewards and earnings * ✅ Handles VAT (7.5%) on your platform fees * ✅ Manages WHT (Withholding Tax) on payouts * ✅ Generates FIRS-compliant tax reports **What you need to do:** * Send us user information (name, NIN/RC number) * Send us transaction data (buys, sells, trades, etc.) * That's it! We handle the rest. #### Who Should Read This? This guide is for developers integrating Caesar. We assume: * ✅ You know how to make REST API calls * ✅ You understand JSON * ❌ **No crypto tax knowledge required** - we'll explain everything * ❌ **No Nigerian tax law knowledge required** - we'll explain everything --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
