Deducting Home Office Expenses

Employees

Unfortunately, home office expenses incurred while working as an employee are not currently deductible. The reason: the Tax Cuts and Jobs Act temporarily suspended the itemized deduction for unreimbursed employee business expenses.

Self-Employed Individuals

The news is better if you are self-employed. You will be eligible for a home office deduction provided you can satisfy certain requirements. The deduction is generally limited to income from the business, and excess expenses may be carried over to the next year.

Direct expenses are costs that apply only to your home office. The cost of painting your home office is an example of a direct expense. Indirect expenses include expenses such as rent, mortgage interest, real estate taxes, maintenance, and homeowners insurance. You can deduct only the business portion of your indirect expenses. These expenses are typically allocated between business and personal use based on square footage.

IRS Requirements

To qualify, a home office — a room or another separately identifiable space — generally has to be used regularly and exclusively for business purposes. The home office also must be (1) your principal place of business; (2) a place where you meet patients, clients, or customers; (3) a separate unattached structure that you use in connection with your business; or (4) a space within your residence that you regularly use to store inventory or product samples in connection with the business.
A home office can qualify if you use it for administrative or management activities and it is the only fixed location where you conduct those activities. Some examples of administrative or management activities include: billing customers; keeping books and records; ordering supplies; setting up appointments.

Simplified Option

If you prefer not to keep track of your expenses, there’s a simplified method that allows qualifying taxpayers to deduct $5 for each square foot of office space, up to a maximum of 300 square feet. When the simplified method is used, qualified mortgage interest and property taxes are separately deductible as itemized deductions.
