If you have a home office, you might qualify to claim a home office deduction. This means you can deduct expenses for the business use of your home. To do so, both of these must apply:
You use the business part of your home exclusively and regularly for trade or business purposes. These uses of your home don’t qualify:
The business part of your home must be one of these:
Your main place of business
Place where you meet or deal with patients, clients, or customers in the normal course of your trade or business
Separate structure -- not attached to the home -- that you use in connection with the your trade or business
Employee Home Office If you work for someone else as an employee, you can deduct home office expenses. However, all of these must apply:
You meet the home office requirements (listed above).
The business use of the home is for the employer's convenience. Factors determining convenience include:
You're required to maintain the home office as a condition of employment.
The functioning of the employer's business isn't possible without your home office.
You can't perform duties properly without the home office.
The employer doesn't provide a space for you to work outside your home office.
The employer requires you to provide your own space.
You don't rent any part of your home to your employer and use the rented portion to perform services as an employee.
Exclusive Use Exclusive use means you use a specific area of your home only for trade or business purposes. The exclusive-use area must meet these requirements:
A room or other separately identifiable space, but it doesn't need to be marked off by a permanent partition
Not used both for business and for personal purposes
Doesn't contain personal-use furnishings like a TV or a couch, though these items are common in many businesses
However, you don't need to meet the exclusive-use test if one of these applies:
You use part of the home for the storage of inventory or product samples. Your home must be the only fixed location of the trade or business. You must use the storage area on a regular basis, and it must be suitable for storage.
You use part of the home as a daycare facility for:
People physically or mentally unable to care for themselves
People age 65 or older
You must meet or be exempt from all state licensing or certification requirements. If you don’t meet the requirements or aren’t exempt from them, you must still meet the exclusive-use test.
Regular Use Regular use means you use part of the home on a continuous, ongoing, or recurring basis.
Principal Place of Business You can have more than one business location for a single trade or business. However, if you deduct home office expenses, your home must be your principal place of business. These factors help you determine if your home office qualifies as a principal place of business:
Relative importance of the activities performed in each business location, like:
Selling or delivering goods or services
Amount of time spent at each location
You can claim a home office deduction if both of these apply:
You use your home exclusively and regularly for:
Administrative activities of your trade or business
Management activities of your trade or business
There's no other fixed location where you conduct substantial:
Administrative activities of your trade or business
Management activities of your trade of business
Administrative or management activities include:
Billing customers, clients, or patients
Keeping books and records
Setting up appointments
Forwarding orders or writing reports
These activities don't disqualify a home office as the principal place of business:
You have others conduct administrative or management activities at locations other than your home. Ex: Another company does your billing from its place of business.
You conduct administrative or management activities at places that aren't fixed locations of the business, like in a car or a hotel room.
You sometimes conduct minimal administrative or management activities at a fixed location outside your home.
You conduct a substantial amount of these business activities at a fixed location outside your home:
You have suitable space to conduct administrative or management activities outside your home. However, you choose to use the home office for those activities.
More Than One Trade or Business If you work in more than one trade or business, follow IRS guidelines to find out if your home office is the principal place of business for each.
A home office might be the main place of business for more than one activity. However, each activity you conducted in the office must meet all requirements for the deduction. Otherwise, you won't meet the exclusive-use test for any activity.
Place to Meet Patients, Clients, or Customers If you meet patients, clients, or customers in your home office in the normal course of business, your home office might qualify for a deduction. You must also meet the regular- and exclusive-use requirements.
What Expenses Are Deductible? Deductible home office expenses include:
Direct expenses to the business part of your home -- like painting and repairs in the area you use for business
Business percentage of indirect expenses for maintaining and running your entire home. This could include these expenses:
You can't deduct expenses for landscaping or lawn care unless you show a business purpose. Ex: You're in a lawn-care business, and you use your lawn as a display to potential clients.
