US Tax Court — Business Tax Debt Litigation — Definition Glossary

Defined by Sarah Mitchell, CPA | Reviewed by: James Okafor, EA | Updated May 2026

Full Definition

The United States Tax Court is the primary federal forum where taxpayers can dispute IRS tax assessments without paying the disputed amount first. Tax Court has jurisdiction over: deficiency notices (90-day letters), Collection Due Process (CDP) appeals, innocent spouse cases, and certain whistleblower award disputes. Filing in Tax Court stops the IRS from collecting the disputed amount during the case. Tax Court has a Small Case Division (S Case) for disputes under $50,000 per tax period — these cases have simplified procedures and lower costs but cannot be appealed. Regular Tax Court cases are formal litigation with full discovery rights, expert witnesses, and appeal rights to the US Circuit Courts. For businesses disputing 941 payroll tax assessments, Tax Court is the primary litigation venue — a Tax Court petition must be filed within 90 days of a Notice of Deficiency or within 30 days of a CDP determination.
