Thomson Reuters Checkpoint Alternative for Small Firms
A self-serve Checkpoint alternative for solo CPAs, enrolled agents, and small firms that primarily need source-linked Code, regulations, IRS guidance, state statutes, and Tax Court opinions. Use it inside the AI tools you already have, starting at $0.
Who's Switching
Checkpoint is strongest when a firm relies on its editorial explanations, treatises, practice aids, and broad research workflow. Some solo practitioners and small firms need a narrower job most days: locate the relevant primary authority, open the source, and keep working in Claude or ChatGPT.
TaxMCP is built for that narrower workflow. Compare the full source coverage and pricing, review the two-minute connector setup, or test the free tier against a question you already know well.

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 day-to-day primary-source lookups.
We're rolling out state tax codes through 2026. If your practice is concentrated in the 29 covered jurisdictions, taxmcp.io may cover those tasks. If not, use it alongside Checkpoint for the states it supports.
Tax Court opinions are now covered on Pro+ (49,000+ cases back to 1942), but other 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 do not yet offer. taxmcp.io is better suited to individual practitioners and small firms.
FAQ
For solos and small firms whose Checkpoint usage is mostly primary-source lookups, taxmcp.io can cover that part of the workflow. For full-service firms that lean heavily on RIA editorial, treatises, and practice aids, it will not replace all of Checkpoint. Evaluate it alongside the research tasks you perform most often.
Checkpoint covers all 50 states. taxmcp.io indexes 29 state and DC tax codes on the Pro+ plan today, with more rolling out through 2026. If the states you need are on the list, it can cover those research tasks; broader 50-state needs remain a gap.
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.
There is no data migration. You sign up, paste a URL into Claude or ChatGPT, and can test taxmcp.io on live research questions while retaining Checkpoint for the work it still covers.
Free tier, no contract. Run the same real question through both tools, inspect the sources, and compare the total review time.
