- 8 - business is conducted in part in the taxpayer’s residence and in part at another location, the following two primary factors are considered in determining whether the home office qualifies under section 280A(c)(1)(A) as the taxpayer’s principal place of business: (1) The relative importance of the functions or activities performed at each business location, and (2) the amount of time spent at each location. See Commissioner v. Soliman, 506 U.S. 168, 175-177 (1993). Because he was a university professor, petitioner’s teaching and research functions at the university were of primary importance. Petitioner’s book writing project (which was performed at his home) was of secondary importance. Petitioner did not show that as a university professor he spent more time working at home than at the university. Accordingly, petitioner’s principal place of business as a university professor was the university. Moreover, we believe petitioner maintained an office in his home not for the convenience of the university, his employer, but rather for his own convenience. See Cadwallader v. Commissioner, T.C.
