Can I Deduct a Home Office? What Business Owners Should Know
Updated: Sep 16
Working from home does not automatically create a home office deduction. A desk, business laptop, LLC registration, or home business address is not enough by itself.
For federal tax purposes, eligibility generally depends on whether a specific part of your home is used for a trade or business and whether that use satisfies applicable requirements. In many situations, the space must be used regularly and exclusively for business and must meet a qualifying business-use test.
If you qualify, you may generally calculate the deduction using either the simplified method or the actual-expense method. The important sequence is qualification first, calculation second.
This guide explains the general federal rules for self-employed individuals, sole proprietors, independent contractors, and other business owners. For a broader look at common business deductions and the rules that determine whether an expense may qualify, see What Can I Deduct in My Business?. Different rules may apply to employees, partners, S corporation shareholders, and other business structures.
Who May Qualify for a Home Office Deduction?
Taxpayers who conduct a trade or business from their home may potentially deduct certain expenses for the business use of the home when the applicable requirements are met. The rules are based on the facts and circumstances of the business and how the space is actually used—not simply on what the space is called.
For these purposes, a “home” may include more than a traditional house. Depending on the situation, it may include:
A house
An apartment
A condominium
A mobile home
A boat
Certain separate structures on the property, such as a detached garage, studio, barn, or greenhouse
A separate structure does not necessarily have to be attached to the home to qualify, but the business use still must satisfy the applicable IRS requirements. Conducting any business activity in one of these locations does not automatically create a deduction.
The nature, frequency, and purpose of the business activity matter. For example, a self-employed consultant who regularly performs administrative work in a dedicated room may have a different analysis from an employee who occasionally answers email from a kitchen counter.
The IRS discusses these rules in Publication 587, Business Use of Your Home. Reviewing that guidance—or discussing the facts with a tax professional—can be useful before claiming the deduction.
Working From Home Does Not Automatically Mean You Qualify
Many people work from home in some capacity. That fact alone does not establish a deductible business use of the home.
The following circumstances do not automatically qualify:
Working remotely for an employer
Checking business email at home
Completing occasional paperwork
Keeping a business laptop at home
Registering an LLC at a home address
Receiving business mail at home
Setting up a desk in a room used for both business and personal purposes
Tax treatment is based on how a particular area is actually used and whether the applicable tests are satisfied. A label such as “home office” does not replace those requirements.
For example, a business owner may use a laptop at home every evening but perform most administrative activities at a separate business location. Another owner may operate the business primarily from a dedicated room in the home. Those situations may produce different results.
Creating an LLC or using a home address can be appropriate for business or administrative reasons, but neither action creates a home-office deduction by itself. Taxpayers should not manufacture a business-use arrangement merely to generate a write-off.
What Does “Exclusive Use” Mean?
The exclusive-use requirement generally means that a specific area of the home is used only for the taxpayer’s trade or business. Personal use of the same area can prevent the space from meeting the test, depending on the circumstances.
The area does not necessarily have to be an entire room or be separated by a permanent wall. A separately identifiable portion of a room may potentially qualify if it is used exclusively and regularly for qualifying business activities.
Consider two contrasting examples:
A dedicated room used only to operate a qualifying business may potentially satisfy the exclusive-use requirement.
A dining-room table used for business during the day and family meals at night generally would not satisfy the exclusive-use requirement.
The room does not need to contain only office furniture. A qualifying office might include filing cabinets, equipment, inventory, or other items used in the business. The central question is whether the area is reserved for business use rather than regularly serving a personal purpose as well.
A guest room that occasionally becomes an office, for instance, may raise a different issue from a room used only for business but furnished in a practical way. Measurements and photographs can help document the space, but documentation does not fix a space that is not actually used exclusively for business.
What Does “Regular Use” Mean?
Business use generally must also be regular rather than occasional or incidental. The IRS does not provide one universal number of hours or days that applies to every situation, so the pattern and significance of the use matter.
Someone who consistently performs qualifying business activities in a dedicated home workspace may potentially satisfy the regular-use requirement. Someone who brings work home a few times during the year and uses a spare room for those occasions generally would not satisfy regular use merely because the space was used for business occasionally.
Regular use may involve activities such as:
Managing business records
Scheduling clients
Preparing proposals or reports
Performing administrative or management work
Meeting qualifying clients or customers
Operating a business from a separate structure
The business activity should be more than an incidental convenience. The appropriate analysis depends on what the business does, how often the space is used, and whether the use is an important part of operating the business.
Are There Exceptions to the Exclusive-Use Rule?
Exclusive use is an important general requirement, but it is not an absolute rule for every home-business situation. The IRS recognizes certain exceptions, including special rules for inventory storage and qualifying daycare facilities.
Storage of Inventory or Product Samples
Certain taxpayers in the wholesale or retail business may qualify for an exception when part of the home is regularly used to store inventory or product samples. Among other requirements, the home generally must be the only fixed location of the business, and the storage must be for use in the taxpayer’s trade or business.
These rules can be technical. The type of inventory, the nature of the business, the location of other business facilities, and the way the space is used may all matter. Storing a few products at home does not automatically establish eligibility.
Daycare Facilities
Qualifying daycare businesses may also be subject to special rules that do not always require exclusive business use of the space. Daycare qualification can involve licensing, certification, registration, or other applicable requirements.
The rules for allocating expenses in a daycare situation can also differ from the general home-office analysis. Anyone operating a daycare business should review the current requirements in IRS Publication 587 rather than applying the standard exclusive-use test without further analysis.
Does the Home Have to Be Your Principal Place of Business?
Principal-place-of-business rules are an important part of determining whether certain home-business use qualifies. A taxpayer may have more than one business location, so having another location does not automatically disqualify the home.
A home may potentially qualify as the principal place of business when the taxpayer uses it exclusively and regularly for administrative or management activities of the business and has no other fixed location where substantial administrative or management activities are conducted.
Examples of administrative or management activities may include:
Billing and bookkeeping
Scheduling
Maintaining business records
Ordering supplies
Managing employees or contractors
Preparing reports or proposals
Checking email at home from time to time is not necessarily enough. The question is whether the home is genuinely used for substantial administrative or management activities and whether the other requirements are satisfied.
Other qualifying uses may exist. For example, a taxpayer may potentially qualify when the home is used regularly to meet or deal with patients, clients, or customers in the normal course of business. Certain uses of a separate structure that is not attached to the home may also qualify without the same principal-place-of-business analysis.
These rules can become complicated when a taxpayer works from multiple locations, shares space, operates multiple businesses, or has access to an employer’s or client’s office. A fact-specific review is often appropriate.
Can Employees Claim a Home Office Deduction?
The federal rules for employees differ from those for self-employed taxpayers and business owners. Generally, employees cannot claim a federal home-office deduction for expenses they personally incur while working from home, even when their employer permits or requires remote work. Different rules may apply to self-employed individuals, statutory employees, partners, and individuals operating through certain business entities, so the taxpayer's business and employment status should be reviewed before determining how home-office expenses should be handled.
That is different from operating a trade or business as a self-employed individual. A sole proprietor or independent contractor may potentially claim qualifying business-use-of-home expenses when the applicable requirements are met.
The analysis can also differ for:
Partners
S corporation shareholders
C corporation shareholders
Employees who incur work-related expenses
Individuals who operate more than one business
Business structure may affect how home-related costs are handled, including whether expenses are deducted directly, reimbursed under an appropriate arrangement, or treated another way. Do not assume that rules for a sole proprietor apply identically to every taxpayer.
State tax treatment may differ from federal treatment. If you are an employee or have a mixed employment and self-employment situation, the relevant federal and state rules should be reviewed separately.
Two Ways to Calculate a Qualifying Home Office Deduction
After determining that the business use of the home qualifies, the deduction generally may be calculated using one of two approaches:
The simplified method
The actual-expense method
Choosing a calculation method does not change the underlying qualification requirements. A taxpayer who does not qualify for the deduction cannot create eligibility simply by selecting the simplified method.
The method that produces the better result can depend on the size of the qualifying area, actual household expenses, ownership or rental status, the period of business use, recordkeeping, income limitations, and future tax consequences.
How Does the Simplified Home Office Method Work?
The simplified home office method reduces some of the calculations and recordkeeping associated with allocating actual household expenses.
Under the current federal simplified option, the calculation generally uses:
$5 per square foot of qualifying business-use space
A maximum qualifying area of 300 square feet
A maximum simplified calculation of $1,500 when 300 qualifying square feet apply for the relevant period and other requirements and limitations are satisfied
The $1,500 figure is not an automatic deduction. It is the maximum result of the simplified calculation before considering applicable limitations and the taxpayer’s specific circumstances. A taxpayer must still establish qualifying business use, including any applicable regular-use, exclusive-use, and place-of-business requirements.
Part-year use, changes in the size or use of the area, and business-income limitations may affect the calculation. The simplified method may also affect how other home-related deductions are handled, so it should not be viewed as automatically better than the actual-expense method.
How Does the Actual-Expense Method Work?
The actual-expense method generally involves identifying qualifying home expenses and allocating the appropriate portion to the business use of the home. The calculation can require more detailed records than the simplified method.
Home expenses are often considered in three categories: direct expenses, indirect expenses, and unrelated expenses.
Direct Expenses
Direct expenses relate specifically to the business portion of the home. For example, painting or repairing only the qualifying office area may be a direct expense.
A qualifying direct expense may generally be treated differently from an expense affecting the entire home. However, the specific treatment depends on the expense and the applicable rules.
Indirect Expenses
Indirect expenses relate to operating and maintaining the entire home. Indirect expenses generally must be allocated between the business and personal portions of the home using a reasonable method. One common approach is to compare the square footage of the qualifying business area with the total square footage of the home. Depending on the home's layout, another reasonable method may sometimes be appropriate.
Depending on the circumstances, potential examples may include:
Utilities
Insurance
General repairs
Mortgage interest
Real estate taxes
Rent
Depreciation for homeowners using the actual method
Not every listed expense is fully deductible. Allocation requirements, limitations, the type of expense, and the taxpayer’s business activity all matter. An arbitrary percentage should not be used simply because it produces a more favorable result.
Unrelated Expenses
Expenses associated only with portions of the home that are unrelated to the business generally are not home-office expenses. For example, landscaping or repairing a room with no relationship to the qualifying business area generally would not become deductible simply because the taxpayer operates a business from the home.
The actual-expense method may provide a different result from the simplified method, but it also requires the taxpayer to support the calculation with appropriate records.
Simplified vs. Actual Expenses: Which Method Is Better?
Neither method is universally better. A comparison may involve:
The size of the qualifying business area
Actual home expenses
Whether the taxpayer rents or owns the home
Administrative and recordkeeping requirements
Depreciation considerations
Applicable income limitations
How long the space was used for business during the year
Eligible taxpayers generally may choose between the simplified and actual methods for a particular tax year. Once a method is selected on a timely filed original return for that year, applicable IRS rules restrict changing to the other method for the same year.
Do not choose solely by looking for the largest current-year number. The actual method may involve depreciation and more detailed records, while the simplified method may reduce administrative work. The appropriate choice depends on the taxpayer’s facts and priorities.

What If You Rent Your Home?
Renters may potentially qualify for a home office deduction when the applicable business-use requirements are met. Home-office deductions are not limited to homeowners.
Under an actual-expense approach, an appropriate portion of qualifying rent and other applicable home expenses may potentially be considered. The allocation should be based on the qualifying business area and the period of business use, rather than an arbitrary estimate.
Renters should also retain lease information, rent records, utility bills, insurance information, and other documentation supporting the calculation. If the business moves or the space changes during the year, those changes may affect the result.
What If You Own Your Home?
Homeowners may also potentially qualify when the applicable requirements are satisfied. Under the actual-expense method, relevant items may include an allocable portion of:
Mortgage interest
Real estate taxes
Utilities
Insurance
Repairs
Depreciation
The specific treatment depends on the expense, the qualifying area, the method used, and applicable limitations. A homeowner should not assume that all household costs become deductible because a room is used for business.
Depreciation associated with business use of a home under the actual-expense method can also have tax implications when the home is later sold. By contrast, depreciation is treated as zero for years in which the simplified method is used, so there is no later depreciation recapture attributable to those simplified-method years. This is one reason to understand the differences between the simplified and actual methods rather than comparing only the current-year deduction. Home-sale rules involve additional considerations, so discussing a potential sale with a tax professional may be appropriate.
Can a Home Office Affect Business Mileage?
A qualifying home office that is also the taxpayer’s principal place of business can affect the tax treatment of transportation between the home and other business locations.
That does not mean that simply claiming a home office converts all driving from home into business mileage. The home office must actually meet the applicable qualification requirements, and vehicle and transportation rules have their own requirements.
For example, travel from a qualifying principal place of business to another work location may be analyzed differently from ordinary commuting between a personal residence and a regular workplace. The facts, destinations, business purpose, and records matter.
Florence Tax LLC has also prepared guidance on business vehicle deductions and the difference between mileage and actual expenses. Avoid treating the home-office analysis as a substitute for reviewing the separate transportation rules.
What Records Should You Keep for a Home Office Deduction?
Good records should support both why the business use qualifies and how the deduction was calculated. Useful records may include:
Measurements of the qualifying business area
Information showing the total area of the home
Receipts
Utility bills
Rent records
Mortgage-interest information
Property-tax records
Insurance records
Repair and maintenance records
Documentation supporting how the space is used
Records relating to depreciation, when applicable
A photograph, receipt, or business registration does not automatically establish qualification. Records should show the actual business use of the space and provide support for the allocation of expenses.
Contemporaneous, organized recordkeeping is generally easier than reconstructing the details later. A simple annual file containing measurements, expense records, and notes about changes in use can help you and your tax professional evaluate the deduction accurately.
Common Home Office Deduction Mistakes
The following misunderstandings can lead to an incorrect claim:
Assuming that working from home automatically qualifies
Using a space regularly for both business and personal purposes while assuming it satisfies exclusive use
Treating occasional work at home as regular business use
Assuming that an LLC registered at the home creates a deduction
Deducting 100% of expenses that benefit the entire home
Using an arbitrary business-use percentage
Assuming the simplified method eliminates qualification requirements
Ignoring special rules for different taxpayer or entity situations
Failing to maintain records supporting the business use and calculation
Assuming a home-office deduction automatically makes all driving from home business mileage
These mistakes often arise because the taxpayer focuses on having a business activity at home rather than evaluating the specific area, frequency, business purpose, and applicable limitations.
When Should You Discuss a Home Office With a Tax Professional?
A discussion may be useful when you are:
Beginning a new home-based business
Establishing a dedicated business space
Moving the business into or out of the home
Using part of the home for both business and personal purposes
Maintaining inventory at home
Operating a daycare business
Deciding between simplified and actual expenses
Using a home office as a potential principal place of business
Using the home in connection with multiple businesses
Changing your business or entity structure
Planning to sell a home that has been used for business
Determining whether transportation from the home may qualify as business mileage
Tax planning is most useful before an important decision is finalized. What Is Proactive Tax Planning—and Why Does It Matter? explains why reviewing tax consequences during the year can provide more choices than discovering those consequences after the fact.

Questions to Ask Before Claiming a Home Office Deduction
Before claiming the deduction, consider these general questions:
Is this area actually used for a trade or business?
Do I use the area regularly for business?
Is the area used exclusively for business, or does an exception apply?
Does my home satisfy an applicable place-of-business requirement?
Am I an employee, self-employed, a partner, or operating through another business structure?
How much of my home is actually used for qualifying business purposes?
Should I evaluate the simplified or actual-expense method?
What records should I maintain?
Could depreciation affect a later sale of my home?
Could a qualifying principal place of business affect how certain business transportation is treated?
Should I discuss my particular home-business arrangement with a tax professional?
These questions are a starting point, not individualized tax recommendations. The correct treatment depends on the nature of the business, how the space is used, the taxpayer’s business structure, and the applicable federal and state rules.
The Bottom Line on the Home Office Deduction
A home office deduction may be available to some self-employed individuals and business owners, but working from home alone is not enough. The space generally must be used in a qualifying way, and requirements involving regular use, exclusive use, principal place of business, or special exceptions may apply.
Once eligibility is established, the simplified method and actual-expense method offer different ways to calculate the deduction. The right choice depends on more than the largest possible current-year amount. Recordkeeping, limitations, depreciation, future transactions, and the taxpayer’s broader circumstances can matter as well.
