Abstract: A computing system for progressive virtual assistance in tax applications includes a computing device with processing circuitry configured to implement a tax application virtual assistant program. The processing circuitry is configured to receive a tax-related user query, identify an intent in the query, and select a workflow including operations required for responding to the intent. The processing circuitry is further configured to implement a workflow orchestrator to schedule a sequence of the operations, identify information needed to complete a target operation, and generate and input an information augmentation prompt to a large language model to retrieve the information. The processing circuitry is further configured to receive a response to the information augmentation prompt, generate and input a user query response prompt to the large language model, receive the user query response, and display the user query response in a chat interface.
