Automate Tax Deduction Processing with GPT-4 Receipt Analysis and Gmail Reporting

How It Works This workflow automates monthly tax processing by ingesting expense receipts alongside revenue data, extracting structured deduction details using GPT-4, and accurately matching expenses to their corresponding revenue periods. It retrieves receipts with built-in type validation, parses deduction information through OpenAI structured output extraction, and consolidates revenue records into a unified dataset. The system then intelligently aligns expenses with revenue timelines, calculates eligible deductions, and generates well-formatted tax reports that are automatically sent to designated agents via Gmail. Designed for accountants, tax professionals, and finance teams, it enables automated expense categorization and optimized deduction calculations.
