If you’re an employee, your use of your home office must be for your employer’s convenience, not just your own. If you’re self-employed, generally your home office must be your principal place of business, though there are exceptions.
Whether you’re an employee or self-employed, the space must be used regularly (not just occasionally) and exclusively for business purposes. If, for example, your home office is also a guest bedroom or your children do their homework there, you can’t deduct the expenses associated with that space.
A valuable break
If you are eligible, the home office deduction can be a valuable tax break. You may be able to deduct a portion of your mortgage interest, property taxes, insurance, utilities and certain other expenses, as well as the depreciation allocable to the office space.
Or you can take the simpler “safe harbor” deduction in lieu of calculating, allocating and substantiating actual expenses. The safe harbor deduction is capped at $1,500 per year, based on $5 per square foot up to a maximum of 300 square feet.
For employees, home office expenses are a miscellaneous itemized deduction. This means you’ll enjoy a tax benefit only if these expenses plus your other miscellaneous itemized expenses exceed 2% of your adjusted gross income (AGI).
If, however, you’re self-employed, you can deduct eligible home office expenses against your self-employment income.
