A U.S. Tax Court matter is litigation, not routine tax preparation. Chase Counsel evaluates the notice, filing deadline, disputed adjustments, available legal and factual defenses, and procedural posture before determining the appropriate response.

Selected matters only. The firm does not provide routine tax-return preparation services.
