Alternative to Thomson Reuters Checkpoint
Tax research with real citations, without the enterprise contract, the seat negotiations, or the portal login. taxmcp.io lives inside the AI tools you already use, starting at $0.
Who's Switching
Solo CPAs, small firms, and independent EAs use Checkpoint less than they pay for it. The contract is annual, the per-seat cost runs well into the thousands per year, and most of the daily work is still “find me §X and tell me what it says.”
taxmcp.io is built for that 80%: fast, cited, federal-source research that lives inside Claude or ChatGPT. Free to evaluate, $9–$29/month if you upgrade, cancel anytime.

Where Checkpoint Wins
RIA explanations, practice aids, and treatises are deep parts of Checkpoint that taxmcp.io doesn't try to replace. Keep Checkpoint for the analysis layer, and use taxmcp.io for the day-to-day primary-source lookups it overcharges for.
We're rolling out state tax codes through 2026. If your practice is concentrated in our 20 covered jurisdictions, taxmcp.io already handles it. If not, run it alongside Checkpoint. You'll still recoup the cost on the states we cover.
Case law, court opinions, and procedural materials sit outside the taxmcp.io scope today. Most controversy work still starts with IRC and Regs research, though, and that part you can still do here, faster.
Large firms with formal vendor reviews may need certifications and SLAs we don't offer at the enterprise tier yet. Individual practitioners inside those firms still use taxmcp.io as a personal research tool.
FAQ
For solos and small firms whose Checkpoint usage is mostly primary-source lookups: yes, and you'll save thousands a year doing it. For full-service firms that lean heavily on RIA editorial, treatises, and practice aids, taxmcp.io won't replace all of Checkpoint. It will still replace the most expensive part of how you use it: the per-seat federal research, where the per-question cost dwarfs the actual workload.
Checkpoint covers all 50 states. taxmcp.io indexes 20 state and DC tax codes on the Pro+ plan today, with more rolling out continuously through 2026. Most solos and small firms have concentrated state exposure. If your top three or four states are on the list, you're covered for the work you actually do. Broader 50-state needs are a gap we're closing, not a feature we're hiding.
Checkpoint is quote-based, with seat pricing that varies widely by tier, modules, and firm size, typically running well into the thousands per user per year for the full federal-plus-state stack. taxmcp.io is $9/month for unlimited federal research, or $29/month with state tax codes. Public, flat, no contract.
No migration, no training, no portal to learn. You sign up, paste a URL into Claude or ChatGPT, and your next research question gets answered with real citations to the IRC, Regs, Pubs, and Rulings. Most people who switch keep Checkpoint running for a few weeks alongside, then drop it at renewal once they realize how much of their actual workload taxmcp.io handles.
