OpenAI, in partnership with financial technology company Thrive and AI firm Crete, has developed a groundbreaking tax agent powered by its Codex model. This self-improving system automates complex tax filings and has already shown the ability to reduce manual workflow time by over 75%.
From Code to Tax Code
Codex, renowned for its ability to translate natural language into computer code, is now being applied to the intricate and rule-based world of tax law. As detailed in a new post from OpenAI, the project leverages the model's deep understanding of structured logic to interpret tax documents, identify relevant deductions, and populate complex forms automatically. This marks a significant expansion from code generation into a specialized professional domain.
A Self-Improving Feedback Loop
The system's core innovation is its human-in-the-loop feedback mechanism, which allows it to learn and improve continuously. This process ensures both high accuracy and adaptation to the ever-changing landscape of tax regulations. The workflow is designed for constant refinement.
- Initial Draft: The Codex-powered agent analyzes financial data and generates a preliminary tax filing.
- Expert Review: A human tax professional at Thrive reviews the draft, making any necessary corrections or adjustments.
- Model Refinement: These corrections are fed back into the system as high-quality training data, fine-tuning the model to improve its accuracy for subsequent filings.
This iterative cycle allows the AI to get progressively smarter with each tax return it processes. For those building similar AI-powered professional tools, understanding these feedback loops is critical.

Boosting Accuracy and Speed
The collaboration with Thrive and Crete has yielded impressive early results. Beyond just speed, the agent is demonstrating a remarkable level of precision, reducing the common errors that often require lengthy audits. In initial trials, the system achieved a 94% accuracy rate on complex itemized deductions, surpassing the typical benchmark for first-year tax associates. This combination of speed and accuracy promises to fundamentally change the economics of tax preparation for both individuals and businesses.
Why It Matters
This project serves as a powerful blueprint for deploying AI in other highly regulated, knowledge-intensive industries like law, compliance, and medicine. By pairing a powerful foundation model like Codex with expert human oversight, OpenAI and its partners have created a system that doesn't just automate tasks but also improves over time. It demonstrates that the future of specialized AI lies in collaborative, self-correcting systems that augment, rather than replace, human expertise.
