Intuit compressed months of tax code implementation into hours — and built a workflow any regulated-industry team can adapt

When faced with the massive and unstructured One Big Beautiful Bill (OBBB), Intuit’s TurboTax team leveraged AI to compress a months-long implementation process into just days, without sacrificing accuracy. They combined commercial AI tools like ChatGPT and Claude with a proprietary domain-specific language and a custom unit test framework. This approach allowed them to quickly analyze the legislation, translate it into their internal coding language, and identify dependencies, focusing development efforts on only the changed provisions.

Crucially, Intuit built new tooling to support this accelerated process, including an automated screen generator and a unit test framework that pinpointed the source of errors and allowed for in-context corrections. The team emphasized the need for near-zero error tolerance in consumer tax products, requiring deterministic results and thorough validation, even of AI-generated output, by human tax experts.

Intuit’s success offers a transferable workflow for other regulated industries facing similar challenges: utilizing commercial LLMs for initial document analysis, shifting to domain-aware tooling for implementation, building robust evaluation infrastructure, and deploying AI tools across the entire organization. This combination of AI and human expertise enabled Intuit to navigate the complexities of the OBBB and deliver a reliable product to its customers.
