TaxBook
Pricing

Pricing that scales with your practice

Every tier includes the full TaxBook research surface — IRC, 26 CFR, court opinions, IRS guidance, and legislative history. All plans support bringing your own AI account so you keep control of model spend and data governance.

Common questions

What does “bring your own AI” mean?
TaxBook calls Claude, GPT-4, or your chosen model using your API key. Your prompts and responses never pass through our shared inference quota, never train a shared model, and stay subject to your existing AI vendor agreement. See the Security page for the full architecture.
Is there an annual discount?
Solo and Team tiers receive a 20% discount when billed annually. Firm contracts are negotiated annually with volume pricing.
Can I try TaxBook first?
Yes. The Solo plan includes a 14-day trial — no card required. For Team and Firm evaluations, book a demo and we’ll set up a 30-day pilot for your group.
Do you support enterprise security reviews?
The Firm tier includes white-glove support for security questionnaires, SOC 2 reports, MSAs, BAAs, and DPAs. We’ll work with your IT and legal teams on data residency and named-subprocessor review.
