Strategic Considerations for Tax Practice

Administrative Exhaustion

Consider pursuing IRS Appeals Office review before filing a Tax Court petition. Appeals conferences can often resolve disputes without litigation costs and preserve all legal rights.

Jurisdictional Considerations

Tax Court has jurisdiction only over certain tax matters and only before payment of the disputed tax. Refund suits must be filed in federal district court or Court of Federal Claims after payment.

Case Size and Complexity

Small Tax Cases (S cases) offer streamlined procedures for disputes of $50,000 or less but waive appeal rights. Consider whether the simplified procedures outweigh the loss of appellate review.

Settlement Opportunities

Tax Court judges actively encourage settlement, and the court offers various settlement procedures including settlement conferences and mediation programs to resolve disputes efficiently.
