Can I Deduct a Home Office for My Business?
Working from home does not automatically make your home expenses deductible.
However, if you are self-employed and use part of your home for your trade or business, you may qualify to deduct expenses related to the business use of your home.
The rules are more specific than simply having a desk, answering business emails from home, or occasionally working at the kitchen table. Your workspace and how you use it must meet certain requirements.
What Qualifies as a Home?
For purposes of the home office deduction, a home can include more than a traditional house.
A qualifying home may include:
A house
Apartment
Condominium
Mobile home
Boat
Similar property that provides basic living accommodations
Certain structures located on your property may also qualify, including an unattached:
Garage
Studio
Workshop
Barn
Greenhouse
A separate structure does not necessarily have to be your principal place of business, but it generally must be used exclusively and regularly in connection with your trade or business.
The Basic Home Office Rules
There are several ways business use of your home can qualify.
Depending on your circumstances, you may qualify if you use part of your home:
Exclusively and regularly as your principal place of business;
Exclusively and regularly as a place where you meet or deal with patients, clients, or customers in the normal course of business;
Exclusively and regularly in connection with your business when using a separate structure that is not attached to your home;
Regularly for qualifying storage of inventory or product samples;
As a qualifying daycare facility; or
For certain rental use.
For most small business owners using an office inside their home, the two concepts that matter most are exclusive use and regular use.
What Does "Exclusive Use" Mean?
Exclusive use means that a specific area of your home is used only for your trade or business.
The area does not have to be an entire room, and it does not need to be separated by a permanent wall or partition. A clearly identifiable portion of a room can potentially qualify.
But when the exclusive-use requirement applies, personal use of that same area can disqualify it.
For example, suppose you have a desk and office area in a spare bedroom that you use regularly for your business. If the rest of the family also routinely uses that same business area for personal activities, the space may fail the exclusive-use requirement.
Remember: Having a computer, desk, filing cabinet, or other business equipment in a room does not by itself turn the room into a deductible home office. It is the actual use of the space that matters.
What Does "Regular Use" Mean?
Your business use must also be regular.
Occasional or incidental business use is not enough.
There is no requirement that you work in the home office every day, but your use of the space should reflect an ongoing and regular part of operating your business.
Whether use is sufficiently regular depends on the facts and circumstances.
Does My Home Have to Be My Only Business Location?
No.
You can conduct business at more than one location and still potentially qualify for a home office deduction.
Your home can qualify as your principal place of business when:
You use the home office exclusively and regularly for administrative or management activities of your trade or business; and
You have no other fixed location where you conduct substantial administrative or management activities of that business.
Administrative and management activities can include:
Billing customers
Keeping books and records
Ordering supplies
Scheduling appointments
Preparing reports
Other administrative functions necessary to operate the business
This rule can be particularly important for contractors, service providers, sales professionals, and other business owners who perform much of their income-producing work at customer locations but manage the business from home.
Example: Maria operates a residential cleaning business. She performs cleaning services at her customers' homes but uses an office in her home exclusively and regularly to schedule customers, maintain the books, prepare invoices, order supplies, and manage the business. If she has no other fixed location where she conducts substantial administrative or management activities, her home office may qualify as her principal place of business.
What If I Meet Clients or Customers at My Home?
Another way to qualify is by using part of your home exclusively and regularly to meet or deal with patients, clients, or customers in the normal course of your business.
The meetings must actually occur at your home, and the use of your home must be substantial and integral to conducting the business.
Occasional meetings or telephone calls are not enough.
The area used to meet customers does not necessarily have to be your principal place of business if the applicable requirements are otherwise met.
What About a Detached Garage, Studio, Workshop, or Other Structure?
A separate structure that is not attached to your home has somewhat different rules.
For example, you might operate your business from a:
Detached garage
Workshop
Studio
Barn
Greenhouse
The structure generally must be used exclusively and regularly for your trade or business.
However, it does not have to be your principal place of business or a place where you meet customers.
Are There Exceptions to the Exclusive-Use Rule?
Yes.
Two important exceptions involve:
Storage of Inventory or Product Samples
You may qualify for a deduction for space regularly used to store inventory or product samples even if the space is not used exclusively for business.
Specific requirements apply, including that your home generally must be the only fixed location of the trade or business of selling products at retail or wholesale.
Daycare Facilities
Special rules also apply to qualifying daycare facilities.
A daycare provider may be able to deduct business use of an area that is regularly—but not exclusively—used for daycare when the applicable requirements are satisfied.
Because daycare calculations involve additional rules, including adjustments based on the amount of time the space is used for daycare, daycare providers should not calculate the deduction using the ordinary home-office rules without considering those special requirements.
How Is the Home Office Deduction Calculated?
Once you determine that the business use of your home qualifies, there are generally two methods available for calculating the deduction:
Simplified method
Actual expense method
You can choose between the methods each tax year.
However, once you elect the simplified method on a timely filed original return for a particular tax year, you cannot later change to the actual expense method for that same year.
Simplified Method
The simplified method uses a prescribed rate rather than requiring you to allocate actual home expenses.
The current prescribed rate is:
$5 per square foot of qualifying business space, up to 300 square feet.
That produces a maximum simplified amount of:
$1,500
For example, if your qualifying home office is 200 square feet:
200 square feet × $5 = $1,000
If your qualifying office is 400 square feet, the calculation is still limited to 300 square feet:
300 square feet × $5 = $1,500
Using the simplified method does not eliminate the underlying qualification requirements. Your home office must still satisfy the applicable business-use rules.
Advantages of the Simplified Method
The simplified method can substantially reduce the calculations and recordkeeping involved.
When using it:
You do not deduct actual expenses attributable to the qualified business use of the home;
You do not claim depreciation for the business use of the home for that year;
Depreciation for that year is treated as zero for purposes of the home-office calculation; and
The simplified method does not reduce the basis of your home through home-office depreciation for that year.
Home-related itemized deductions that are otherwise allowable, such as qualified mortgage interest and real estate taxes, are generally handled under their normal individual tax rules without allocating a portion to the home office under the simplified method.
Actual Expense Method
The actual expense method calculates the deduction using actual costs associated with operating your home.
Expenses can generally be divided into direct and indirect expenses.
Direct Expenses
A direct expense relates only to the business portion of your home.
For example, if you repair or paint only your qualifying home office, that may be a direct expense attributable to the business area.
Indirect Expenses
Indirect expenses relate to maintaining and operating the entire home.
Depending on the circumstances, these may include items such as:
Rent
Mortgage interest
Real estate taxes
Utilities
Insurance
Repairs and maintenance
Depreciation
The deductible portion of indirect expenses is generally determined based on the percentage of the home used for business.
How Do I Determine the Business-Use Percentage?
A common method is to compare the square footage of the area used for business with the total square footage of the home.
For example:
Home office: 200 square feet
Total home: 2,000 square feet
200 ÷ 2,000 = 10% business use
The applicable percentage can then be used to allocate qualifying indirect expenses under the actual expense method.
When the rooms in a home are approximately equal in size, another reasonable method may sometimes be available based on the number of rooms used for business compared with the total number of rooms.
Whatever method is used should reasonably reflect the business use of the home.
What About Depreciation?
This is an important difference between the two methods.
When using the actual expense method, depreciation attributable to the qualifying business portion of an owned home may be part of the calculation.
Depreciation can also affect the tax consequences when the home is later sold.
You cannot simply choose not to account for depreciation in order to avoid its later tax consequences. Federal tax rules generally require the home's basis to reflect depreciation that was allowed or allowable for the business use.
Under the simplified method, depreciation for the home-office calculation is treated as zero for the years that method is used, and the home's basis is not reduced by home-office depreciation for those years.
Remember: The simplified method isn't automatically the better method, and the actual expense method isn't automatically the better method. The better result depends on the size of the qualifying space, actual home expenses, business income, whether you rent or own the home, and other circumstances.
Can the Home Office Deduction Create a Business Loss?
The deduction is subject to an income limitation.
Home-office expenses cannot simply create or increase a business loss without regard to those rules.
Under the actual expense method, certain otherwise allowable expenses that are limited may be carried forward to a later year, subject to the applicable limitation in that later year.
The simplified method does not provide a carryover of a simplified deduction that was disallowed because of the income limitation.
What Records Should I Keep?
Your records should establish both that the space qualifies and how the deduction was calculated.
Depending on the method used, consider maintaining:
Documentation showing the size and location of the business area
Total square footage of the home when relevant
Photographs or a floor plan showing the designated business area
Records supporting regular and exclusive business use
Utility bills
Rent records
Mortgage interest records
Real estate tax records
Insurance records
Repair and maintenance receipts
Records of direct home-office expenses
Depreciation records when applicable
Your home-office calculation
Prior-year home-office carryovers when applicable
You do not have to use a particular recordkeeping system, but your records need to provide the information necessary to support the deduction.
For more information about maintaining business records generally, see our What Business Records Should I Keep—and for How Long? guide.
Does a Home Office Affect Business Mileage?
Potentially—and this is an important connection many business owners miss.
If your home qualifies as your principal place of business, transportation between that home office and another work location in the same trade or business may qualify as deductible business transportation rather than nondeductible commuting.
That does not mean simply having a desk at home converts your commute into deductible mileage. The home office must actually qualify as the principal place of business under the applicable rules.

Can Employees Deduct a Home Office?
For federal income tax purposes, the home-office deduction discussed in this guide is generally relevant to self-employed individuals and certain partners.
Employees generally cannot claim a federal home-office deduction for unreimbursed employee expenses under current federal rules.
That distinction matters because working remotely—even when required by an employer—does not by itself create the same federal home-office deduction available to an eligible self-employed taxpayer.
Frequently Asked Questions
Can I deduct my home office if I work at my kitchen table?
Usually not if the same area is also used personally and the exclusive-use requirement applies. A qualifying area does not have to be an entire room, but it generally must be identifiable and used exclusively and regularly for business.
Does my home office have to be a separate room?
No. A separately identifiable area within a room can potentially qualify. A permanent wall or partition is not required.
Can I deduct a home office if I also work somewhere else?
Possibly. A home office can qualify as your principal place of business when it is used exclusively and regularly for administrative or management activities and you have no other fixed location where you conduct substantial administrative or management activities. Other qualification rules may also apply.
Is the simplified method always $1,500?
No. The deduction is calculated using the qualifying square footage at $5 per square foot, subject to the 300-square-foot maximum and the applicable income limitation. $1,500 is the maximum simplified amount, not an automatic deduction.
Can I switch between the simplified and actual expense methods?
Yes. You can generally choose the method separately each tax year. However, once the simplified method is elected for a particular year on a timely filed original return, you cannot later switch methods for that same tax year.
Can I deduct my entire internet bill because I work from home?
Not simply because you have a home office. Expenses must be allocated appropriately when they have both business and personal use, and different expense rules may apply depending on the nature of the cost.
Does claiming a home office automatically make mileage from my house deductible?
No. The relevant issue is whether the home qualifies as your principal place of business. When it does, transportation between the qualifying home office and another work location in the same trade or business may be deductible.
