The requirements that you must meet in order to claim a home office deduction are strict and they are strictly enforced. To deduct home office expenses, you must satisfy tests relating to the space itself--exclusive and regular use--and the purpose of your use--principal place of business or meeting customers. Let's examine each of these requirements in turn.
Regular Business Use Is Essential
To qualify as a home office for tax purposes, it is essential that you use the space "regularly." Occasional use is not sufficient. If your office is your principal place of business, you will have no trouble meeting the "regular use" requirement.
However, if your home office isn't your principal place of business, but you use it to meet with clients, then you may find the regular use requirement challenged. A few client meetings over the course of the year is not going to entitle you to a deduction. It is necessary to prove that you regularly meet with clients.
As with any business deduction, you must keep good records to substantiate your claims. At the minimum, record the date and length of each meeting.
Although it's nearly always called the "home office" deduction, you don't necessarily have to use a portion of your home as an office: you could use part of your home as a showroom, lab, or storage area.
Space Must Be Used Exclusively for Business
You must use the space exclusively for business. The exclusive use requirement is construed very strictly. Many deductions are lost because the space is not used exclusively for business.
"Exclusive use" means that the business part of the home can not be used for any (not even the slightest!) personal, family, or investment activities, or for any other business activities that don't meet the home office requirements.
If your return is audited, and you have claimed a home office deduction, don't be surprised if the IRS wants to visit your home office as part of a field audit. They will be looking for games or your kid's homework assignments on the computer. They will be looking for recreational equipment, such as a TV or a Wii Fit in the office space.
And, yes, an employee at a desk in a traditional office may well have Angry Birds or the novel that he or she is writing on the computer and the IRS would not blink. But don't expect that same treatment when a home office deduction is being scrutinized. (It's tax law--it's not supposed to be fair.)
However, keep in mind that the home office deduction refers to writing off a portion of your otherwise non-deductible house expenses (such as the electric bill.) So, if you didn't claim a home office deduction, but only a deduction for the business use of that computer, the mere existence of a few personal files would not cost you that deduction
Exceptions to Exclusive Use Requirement
There are a few exceptions to the "exclusive use" requirement:
- Inventory storage provided the home is the only fixed location of a retail business;
- Licensed day care facility; and,
- Separate structures.
Inventory storage exception. If your home is the only fixed location of a retail or wholesale business, you can deduct expenses that pertain to the use of part of your home for the storage of inventory or product samples.
Patrick Daley's home is the sole, fixed place of his business selling personal computers at retail. He regularly uses half of his basement for inventory storage, although he also uses that part of the basement for personal purposes when his inventory is low. The expenses allocated to the storage space are deductible even though he does not use that part of the basement exclusively for business.
In order to meet the home office requirements, your home must be used regularly and exclusively for business—unless you meet one of the exceptions. Your home must also be your principal place of business, or be used to personally meet with clients or customers in the normal course of your business.
Day care provider exception. There is also an exception to this exclusive use requirement for those who operate a child care business in their home. The portion of the home that is used regularly for day care qualifies as a "home office," even if it is also used for personal and family living space. However, day care operators face an additional time restriction: they may only deduct expenses for the actual time the day care center was open.
Separate structure exception. If your home office is a separate structure that is not attached to your residence, you may qualify for the home office deduction without meeting the exclusive use requirement. In this situation, the structure merely has to be used in your trade or business.
