AgenTax

AgenTax helps engineering, tax, and consulting teams produce stronger R&D tax credit documentation for Canada (SR&ED) and the United States (IRC Section 41). Instead of year-end reconstructed timesheets, AgenTax connects to tools teams already use — Jira, Linear, GitHub, and workforce/CSV imports — then supports narrative write-ups, eligibility determinations, time allocation support, and exportable packages for tax return filings. AgenTax is a documentation enablement platform. It provides R&D tax credit support, determines final eligibility/qualifications, calculates credits for filings, or submits claims/studies to CRA or IRS. Note: AgenTax at agen-t-ax.com is not affiliated with AgentTax at agenttax.io (an unrelated sales-tax API for AI agent commerce).
