You cannot use your home office for both personal and business use if you want to claim a deduction. The IRS guidelines state that the areas being claimed must be regularly and exclusively used for working on the job. For example, you cannot claim a deduction for your bedroom, because that’s your sleeping area as well. Some taxpayers have gotten into trouble by trying to claim portions of a larger space. The IRS is strict when it comes to exclusive use, and you should be, too. As far as the regular use goes, working for your employer each day in your home office is more than enough to pass the test, even if it’s just for a few hours. The final test for an allowable deduction requires you to meet one of the following three requirements:
- Home office must be principal place of business: That’s where you primarily get all of your work done.
- Where you meet clients, customers or patients.
- The home office is a separate structure.
If you rent your home office to your employer, then you can claim limited deductions.
