How do notices of deficiency differ from standard audit adjustments in terms of appeal rights?

• A. A deficiency notice typically gives the right to petition the Tax Court; standard audit adjustments allow protests and Appeals.
• B. A deficiency notice allows no appeal rights; standard audit adjustments allow appeals.
• C. A deficiency notice is issued after settlement; standard audit adjustments trigger only civil penalties.
• D. A deficiency notice always ends the case; standard audit adjustments always go to federal district court.

Answer: (A)

A deficiency notice sets up a direct route to the U.S. Tax Court. After the IRS determines there’s a deficiency, you receive a notice that gives you a limited window to petition the Tax Court for a judicial review of the IRS’s determination. You don’t go through the IRS Appeals process first, and you typically don’t have to pay the deficiency to file the petition.

Standard audit adjustments, by contrast, are handled through the IRS Office of Appeals. If you disagree with those adjustments, you file a protest and may request an Appeals conference to try to settle. Litigation is only pursued after the Appeals process if you still can’t reach an agreement, and the path there generally involves the tax being assessed first. So the key difference is the appeal route: deficiency notices offer direct Tax Court review, while standard audit adjustments are resolved through the Appeals process with litigation as a later option.
