1. Generally, in order to claim a business deduction for your home, you must use part of your home exclusively and regularly:
- as your principal place of business, or
- as a place to meet or deal with patients, clients or customers in the normal course of your business, or
- in any connection with your trade or business where the business portion of your home is a separate structure not attached to your home.
3. Generally, the amount you can deduct depends on the percentage of your home used for business. Your deduction for certain expenses will be limited if your gross income from your business is less than your total business expenses.
4. There are special rules for qualified daycare providers and for persons storing business inventory or product samples.
5. If you are self-employed, use Form 8829, Expenses for Business Use of Your Home to figure your home office deduction and report those deductions on line 30 of Form 1040 Schedule C, Profit or Loss From Business.
6. If you are an employee, additional rules apply for claiming the home office deduction. For example, the regular and exclusive business use must be for the convenience of your employer.
