When possible, you want to claim that your office in your home qualifies as a principal place of business, because this classification
gives you the home-office deduction, and
eliminates commuting from your home to your regular office.
Current law gives you two ways to claim your office in the home as a principal office:
First, as a principal office under the rules that the Supreme Court finalized in Soliman
Second, as a principal office under the alternative after-Soliman rules, where lawmakers added this alternative: “... the term principal place of business includes a place of business which is used by the taxpayer for the administrative or management activities of any trade or business of the taxpayer if there is no other fixed location of such trade or business where the taxpayer conducts substantial administrative or management activities of such trade or business”
Question for you: If you have an office downtown where you spend 40 hours a week, can you claim that you have an office in your home that qualifies as a principal office if you spend only 12 hours a week working in the home office? If you said no, you are not alone. But you would also be wrong.
With the administrative or management rule, you can have your principal office in your home with 12 hours of work even when you work at your other office for 40 hours.
