tax legal skills for United States

The United States tax system is among the most complex in the world, spanning the Internal Revenue Code, Treasury regulations, IRS guidance, and a parallel layer of state and local taxes that vary significantly across fifty jurisdictions. Federal corporate tax, pass-through entity rules, international provisions like GILTI and BEAT under the Tax Cuts and Jobs Act framework, and transfer pricing all demand precision that generic research tools rarely supply. The tax legal skills for the United States in the ThomasMore catalog are built for that density — each one agent-ready, targeting a concrete task such as analyzing Subchapter S eligibility, mapping withholding obligations on cross-border payments, or assembling a Section 382 limitation checklist.

These skills run over MCP or download directly into your workflow, integrating with the way transactional and controversy counsel actually operate. Whether your matters sit in M&A structuring, partnership allocations, IRS examination responses, or state nexus analysis, filtering the ThomasMore catalog by practice area, license, or author surfaces the capability your file requires. Authors maintain these skills as the IRS issues rulings, Treasury releases proposed regulations, and courts hand down decisions in the Tax Court or the circuit courts. Start with the sub-area your current matter touches to find what is ready to run.
