TaxGPT
TaxGPT is an AI research assistant built specifically for tax professionals and trained on the tax code, IRS guidance, and case law. r/taxpros threads describe it as "quite effective" for first-pass research, with answers that cite the source code section so a preparer can verify before relying on it. It is built for accountants, not for someone filing a single 1040.
Key Features:
- ✓Answers cite specific Internal Revenue Code sections and IRS publications
- ✓Built for CPA and EA workflows, not consumer tax filing
- ✓Used for first-pass research on multi-state and entity-level questions
- ✓Drafting support for client memos and emails
Pricing:
Paid plans, roughly $2,000 to $2,500 per year for professional tiers
Pros:
- + Source citations let preparers verify the answer instead of trusting it blindly
- + Reddit users in r/taxpros call it effective for routine research questions
- + Cuts time spent searching IRS publications for common scenarios
Cons:
- - Annual pricing in the $2,000 to $2,500 range puts it out of reach for individual filers
- - Still requires a licensed preparer to confirm anything before it goes on a return
- - Less reliable on edge cases like multi-state or international filings, per r/tax discussions
Best For:
CPAs, EAs, and tax firms that want a faster first pass on research questions, with a human always checking the citation before using the answer.
