- 5 - Commissioner, supra at 610-611; Goza v. Commissioner, supra at 182-183. If Commissioner submits a proof of claim for unpaid Federal tax liabilities in a taxpayer’s bankruptcy action, the taxpayer has had the opportunity to dispute the liabilities for purposes of section 6330(c)(2)(B). See Kendricks v. Commissioner, 124 T.C. 69 (2005); Hassell v. Commissioner, T.C. Memo. 2006-196; Drake v. Commissioner, T.C. Memo. 2006-151; Sabath v. Commissioner, T.C. Memo. 2005-222. In petitioner’s bankruptcy proceeding, respondent submitted proofs of claim for petitioner’s unpaid income tax liabilities for 1989, 1990, and 1998. Petitioner did not dispute these tax liabilities. Accordingly, petitioner cannot challenge his underlying liabilities herein. Petitioner has failed to raise a spousal defense, make a valid challenge to the appropriateness of respondent’s intended collection action, or offer alternative means of collection. These issues are now deemed conceded. See Rule 331(b)(4). Accordingly, we conclude that respondent did not commit any abuse of discretion, and we sustain respondent’s determination to proceed with collection. To reflect the foregoing, An appropriate order and decision will be entered.Page: Previous 1 2 3 4 5Last modified: November 10, 2007
