- 7 - balances the need for the efficient collection of taxes with petitioners’ legitimate concern that respondent’s collection be no more intrusive than necessary. In reviewing whether respondent’s Appeals Office abused its discretion in sustaining respondent’s notice of intent to levy, our analysis is governed by “general principles of contract law.” See Dutton v. Commissioner, 122 T.C. 133, 138 (2004). Under the “material breach of contract” analysis applied in Robinette v. Commissioner, 123 T.C. 85, 108 (2004), revd. 439 F.3d 455 (8th Cir. 2006), “If * * * [petitioners’] breach is material and sufficiently serious, * * * [respondent’s] obligation to perform may be discharged. * * * Not so, however, if * * * [petitioners’] breach is comparatively minor.” On appeal, the Court of Appeals for the Eighth Circuit noted that the failure to comply with an express condition of an OIC is itself grounds for the Commissioner to revoke the OIC, regardless of materiality. Robinette v. Commissioner, 439 F.3d at 462. Generally, for purposes of section 6330, a notice mailed to the taxpayer’s “last known address” is proper and sufficient. Tadros v. Commissioner, 763 F.2d 89, 91 (2d Cir. 1985); Buffano v. Commissioner, T.C. Memo. 2007-32. In determining petitioners’ last known address, unless otherwise notified respondent may rely upon petitioners’ most recently filed return.
