   What You Need To Know About the Home Office Deduction

© 2003 by Lynne Ganoe

The home office deduction is a great little perk to the home-based business owner.  Being able to write off a portion of your personal expenses not only reduces the income tax that you owe, but also reduces self-employment taxes.  But it's important to know the rules to be sure that you qualify, and to keep good records to back up your deductions.  Here's a rundown of what you need to know if you are planning to take the home office deduction.  

Qualifying for the Home Office Deduction

First you need to make sure that you qualify.  Your home office may be in any type of residence such as a house, apartment, condominium, mobile home, or boat. You do not need to own your home in order to claim an "office in the home" deduction. Also, the area does not necessarily need to be located IN your home; for instance, a garage or other separate structure can be considered when determining whether you qualify for the deduction.

To qualify for a home office deduction, you must use an area of your home regularly and exclusively for business purposes and you must meet at least one of these conditions:  

  • You use the space as your principal place of business, and the business generates revenue. Under recent changes in the law, you can meet this qualification even if you only perform administrative and managerial functions there and if you have no other fixed principal place of business. 

  • You use the space to meet with clients, patients or customers. 

  • You use the area exclusively to store inventory or product samples for your wholesale or retail business.



Exclusive Use

Remember that your home office must be used solely for business purposes.  If you also use your home office to watch TV or build model airplanes, you can't claim the home office deduction. 

Exceptions to Exclusive Use

You do not have to meet the exclusive use test if either of the following applies:

  • You use part of your home for the storage of inventory or product samples (discussed next).

  • You use part of your home as a day-care facility.

Storage of inventory or product samples. If you use part of your home for the storage of inventory or product samples, you can claim expenses for the business use of your home without meeting the exclusive use test. However, you must meet all of the following tests:

  • You sell products at wholesale or retail as your trade or business. 

  • You keep the inventory or product samples in your home for use in your trade or business. 

  • Your home is the only fixed location of your trade or business.

  • You use the storage space on a regular basis.

  • The space you use is an identifiably separate space suitable for storage.

Example: Your home is the sole fixed location of your business of selling hand-made soaps.  You regularly use half of your basement for storage of inventory and product samples. You sometimes use the area for personal purposes. The expenses for the storage space are deductible even though you do not use this part of your basement exclusively for business.

Rule for Employees

To qualify for the home-office deduction, an employee must satisfy two additional criteria:

  • First, the use of the home office must be for the convenience of the employer (for example, the employer does not provide a space for the employee to do his/her job).

  • Second, the taxpayer does not rent all or part of the home to the employer. Employees who telecommute may be able to satisfy the requirements for the home-office deduction.

Figuring the Percentage

You can use any reasonable method to determine what percentage of your home is used for business, but the following are two common ways to come up with the business use percentage:

  • Divide the area (width multiplied by length) of the portion of your home used for business by the total area of your home.  For example, if your home office is 10 feet by 15 feet, the total area of your office is 150 square feet (10 x 15 = 150).  If the total square footage of your home is 1,300 sq. feet, then you would divide 150 by 1300, resulting in a percentage of 12% (150 / 1300 = .12).

  • If you use one room of your home for business and all the rooms in your home are approximately the same size, you can just divide 1 by the total number of rooms in your home.  For instance, if you have a 5-room house and you use one room for business, 1 / 5 = .20, or 20%.



Whatever percentage you come up with is what you would multiply your qualified indirect expenses by to determine the deductible amount.

What is Deductible?

Home office expenses are divided into two categories: Direct and Indirect costs.

Direct costs are expenses only for the business portion of your home, such as painting and repairs only in the area used for business. These costs are deductible in full.

Indirect costs are those costs associated with keeping and running your entire home such as insurance, utilities, and general repairs. These costs are deductible based on the percentage of your home used for business.

Unrelated costs are expenses related only to the part of your home not used for business (such as lawn care or painting a room not used for business) and are not deductible.

Certain expenses of your home are deductible whether you have a business or not. Real estate taxes, mortgage interest, and casualty losses can all be deducted as itemized deductions on your personal tax return.  For these deductions, take the business usage percentage of these costs as a home office deduction, and deduct the balance on your Schedule A as itemized deductions.

Other expenses, such as depreciation, insurance, rent, repairs, security systems, utilities and services are only deductible if you have a home office. You can deduct the portion of these expenses that apply to the business use of your home using the business percentage calculated earlier.

A note about telephones:  the basic telephone service charge for the first telephone line into your home is a non-deductible personal expense. However, any business long-distance charges made on that line, as well as the cost of a second line into the home that is used exclusively for business, are deductible business expenses. They can be deducted even if you do not qualify for the home office deduction.  They should be included in your business expenses on your Schedule C. 

Keep in mind that if you use a very small percentage of your home as an office, such as 10%, you need to use that percentage to compute your deduction for utilities, trash removal, mortgage interest, real estate taxes, and rent. The deduction, then, may not amount to as much as you anticipated. But it is worth your while to gather the information and see what it would be.  Here is a handy little tool that will help you calculate what the home office deduction would be for you:  http://www.toolkit.cch.com/text/P07_2740.asp

Another thing to keep in mind is that the home office deduction cannot trigger a loss for your business.  For instance lets say that you had business income of $20,000 and business expenses (not including the home office deduction) of $17,000.  This leaves you with a net profit of $3,000.  If your home office expense is $5,000, you would only be able to claim $3,000 for the home office expense.  If you already have zero income or a loss before the home office deduction, you won't be able to take any of it.  However, all is not lost, as you can "carry forward" any home office deduction that you are not able to take because of this rule.  This means you can apply any unused portion to future tax years.

Complications When Selling your Home

If you qualify for and claim the home office deduction, there will be additional issues to deal with when it comes time to sell your home. 

First of all, any depreciation you take (or were eligible to take) will reduce the basis of your home, and consequently have an impact on any capital gains tax you may owe on the sale.  For many people, this won't be an issue.  The way the law stands now, if you have lived in your home and used it as your principal residence for two of the five years prior to selling your home, you can exclude from income up to $250,000 (or $500,000 if married filing jointly) of any gain you receive on the sale of your home.  This means that as long as you make less than $250,000 (or $500,000 MFJ) profit when sell your home, you will not owe any capital gains tax on the sale.  HOWEVER, if your business area is located in a separate structure, such as a garage or other free-standing structure located on your property, the capital gains tax exclusion DOES NOT APPLY to this part of the sale, and you may end up owing capital gains taxes on a percentage of the profit.  If this situation applies to you, I recommend you talk with a tax professional before selling your home to see how this will affect you. 

But whether your business use is outside your residence or inside, if you have claimed the home office deduction you will have to  "recapture" any depreciation you took (or could have taken) for business use of your home after May 6, 1997, up to the amount of any gain realized on the sale.  This means that the amount of any depreciation you took (or could have taken) will be taxed at a rate of 25% in the year you sold your home.

Depreciation "Allowed and Allowable"

The "depreciation allowed or allowable" rule means that you cannot avoid either the reduction in basis of your home, or the depreciation recapture rule by just not claiming depreciation as a home office deduction.  Whether you claim the depreciation or not, if you qualified for the home office deduction, the amount of depreciation you COULD HAVE CLAIMED will need to be deducted from your home's basis, and recaptured in the year of sale.

As you can see, the home office deduction is a bit complicated and not everyone that works from home will qualify.  But if you haven't at least looked in to the possibility, you owe it to yourself to do so now.  And if you qualify but have not taken it because of concerns about selling your home, the recent changes that remove most home offices from capital gains taxation is a good reason to re-think your decision.
