Title 26 › Subtitle Subtitle F— - Procedure and Administration › Chapter CHAPTER 63— - ASSESSMENT › Subchapter Subchapter B— - Deficiency Procedures in the Case of Income, Estate, Gift, and Certain Excise Taxes › § 6215
If a taxpayer asks the Tax Court to decide a tax dispute, the amount the court finally decides is the deficiency must be assessed and paid after the Secretary gives notice and demand. Any amount the Secretary called a deficiency but the Tax Court finally rejects cannot be assessed or collected by levy or by suing in court. Related rules are in other sections: appeals and collection while an appeal is pending (section 7485), dismissal of a petition treated as affirming the Secretary’s deficiency (section 7459(d)), a Tax Court finding that tax is time-barred treated as no deficiency (section 7459(e)), damages for suits meant only to delay (section 6673), general Tax Court rules (subchapter C of chapter 76), and extensions to pay a deficiency (section 6161(b)).
