Qualification Requirements
To qualify for the home office deduction under the general U.S. federal rules described in this guide, the relevant part of your home must generally be used regularly and exclusively for business. You must also meet one of the applicable qualification tests, such as the following:
- Principal place of business: You use the space regularly and exclusively as your principal place of business.
- Meeting clients or customers: You use the space regularly to meet or deal with clients, customers, or patients in the normal course of business.
- Administrative or management activities: You use the space regularly and exclusively for administrative or management activities related to your business, and you have no other fixed location where you conduct a substantial amount of those activities.
A separate structure that is not attached to your home, such as a studio or workshop, may also qualify if it is used regularly and exclusively for your trade or business and meets the relevant requirements.
The Exclusive-Use Test
The exclusive-use test generally requires a specific area of your home to be used only for business purposes. Using the same room for personal activities may prevent it from qualifying, although certain exceptions exist under U.S. tax rules, including specific rules for qualifying inventory storage and daycare activities.
The Regular-Use Test
The regular-use test requires the space to be used for business on a continuing basis. Occasional or incidental business use generally does not meet this requirement.
Determining Your Principal Place of Business
When determining whether a home office is your principal place of business, relevant considerations may include:
- Whether you use the home office to conduct administrative or management activities and have no other fixed location where you conduct a substantial amount of those activities.
- Whether the home office is the primary location where you conduct substantial business activities, considering the nature and importance of the work performed there.
The determination depends on the circumstances of the business and the applicable IRS rules. It is not necessarily based only on the amount of time spent in the home office or whether the business generates revenue there.
Home Office Deduction for Employees
Rules for employees differ from those for self-employed individuals and other business owners.
The Tax Cuts and Jobs Act of 2017 suspended certain miscellaneous itemized deductions for employees for tax years 2018 through 2025, including deductions for many unreimbursed employee business expenses. The original source describes this historical restriction in relation to employee home office expenses.
Before the suspension, employees generally had to meet additional requirements to claim a home office deduction. These included demonstrating that the home office was maintained for the convenience of the employer rather than merely for the employee’s convenience.
Employees also generally could not rent the home office space to their employer and use that rented portion to perform services as an employee for the same employer under the rules described in the source.
Employees who work remotely or telecommute should not assume that working from home automatically qualifies them for a federal home office deduction. Eligibility depends on the tax year and applicable law. Employer reimbursement arrangements may also have separate tax implications.
Types of Home Office Expenses
Home office expenses can generally be grouped into three categories: direct business expenses, indirect business expenses, and unrelated expenses.
1. Direct Business Expenses
Direct business expenses relate specifically to the business portion of your home. Examples may include:
- Additional telephone lines used for business.
- Business-related long-distance calls.
- Optional telephone services used for business purposes.
- Repairs made specifically to the qualifying business area.
Under the U.S. rules described in the original source, basic local telephone service charges for the first telephone line in a residence generally do not qualify as a business deduction for home office purposes. The treatment of other communication expenses depends on their business use and the applicable rules.
2. Indirect Business Expenses
Indirect expenses relate to operating and maintaining the home as a whole. Depending on eligibility and the method used, these may include:
- Mortgage interest or rent.
- Homeowners or renters insurance.
- Real estate taxes.
- Utilities.
- General repairs and maintenance.
- Eligible depreciation on the business portion of the home.
Under the regular method, eligible indirect expenses are generally allocated between business and personal use according to the applicable rules.
3. Unrelated Expenses
Expenses that have no qualifying connection to the business portion of the home are generally not deductible as home office expenses. Examples include painting a room used exclusively for personal purposes or ordinary lawn care that does not qualify under the applicable rules.
Keep records of expenses and how they relate to the qualifying business space so you can substantiate any deduction claimed.
Home Office Deduction Limits
The amount you can deduct for business use of your home may be limited by the income generated from the relevant business activity and other applicable tax rules.
Under the general U.S. federal rules described in the source, if qualifying gross income from the business use of the home is sufficient to cover the applicable business expenses, you may be able to claim eligible deductions subject to the relevant limitations.
If the qualifying income is less than the expenses otherwise available for deduction, certain expenses related to the use of the home may be limited.
The calculation may take into account:
- The business portion of certain expenses that may be deductible even if you did not use your home for business, such as qualifying mortgage interest and real estate taxes.
- Other allowable expenses related directly to the business activity, such as business telephone costs, supplies, and depreciation on business equipment.
- Eligible expenses associated with operating the home, such as insurance, utilities, repairs, and depreciation allocated to business use.
Under applicable rules, some deductions that cannot be used in the current year because of the income limitation may be carried forward to a later year. Their availability remains subject to the relevant limitations and requirements.
Because the calculation can be complex, consult a tax professional to determine which expenses qualify and how any limitation or carryforward applies to your circumstances.
Selling a Residence Used for Business
If you use your property both as a home and for business, special rules may apply when you sell it.
Under U.S. federal tax law, eligible taxpayers may qualify to exclude a portion of the gain from the sale of a principal residence, subject to ownership, use, and other requirements. The original source cites exclusion limits of $500,000 for certain married taxpayers filing jointly and $250,000 for certain single taxpayers and married taxpayers filing separately. Eligibility and limits should be verified for the relevant circumstances and tax year.
The general ownership and use tests described in the source require that, during the five-year period ending on the date of sale, the taxpayer:
- Owned the home for at least two years.
- Used the home as their main residence for at least two years.
Other requirements and exceptions may apply.
Business Use Within the Home
When the business area is within the home itself, such as a room used as a home office, the rules may allow the residence exclusion to apply without allocating the gain between the business and residential portions in certain circumstances. However, depreciation claimed or allowable for business use may have separate tax consequences.
Business Use in a Separate Structure
If a separate part of the property, such as a detached garage or outbuilding, is used for business, different allocation rules may apply. The outcome may depend on how the structure was used, whether it meets the relevant residence-use requirements, and whether it was used for business in the year of sale.
Before selling a property used partly for business, consult a qualified tax professional to understand how the home office, depreciation, and residence-sale rules interact.
Simplified Home Office Deduction
The IRS introduced an optional simplified method for calculating the home office deduction beginning with the 2013 tax year. It can reduce the recordkeeping and calculation required compared with the regular method.
Under the simplified method described in the original source, the deduction was calculated at $5 per square foot for up to 300 square feet, for a maximum of $1,500 per year. These are the standard rates and limits described in the source; confirm the applicable rules before using them for a current tax return.
Under the simplified method:
- The deduction is based on the eligible area used for business, subject to the applicable maximum.
- You generally do not claim depreciation on the business portion of the home through the simplified calculation.
- Eligible mortgage interest, real estate taxes, and certain other expenses may still be treated under the applicable rules.
- Other qualifying business expenses unrelated to the home, such as advertising, supplies, and employee wages, may remain deductible separately.
The simplified method does not remove the underlying qualification requirements. The space must still meet the relevant business-use tests, and the deduction may be limited by income from the business.
The simplified method and regular method can produce different results. Compare the options with a qualified tax professional to determine which method is appropriate for your circumstances.
Home Office Tax Deduction Benefits
The home office deduction can allow eligible taxpayers to deduct a qualifying portion of expenses that would otherwise be personal household costs. Depending on the method and applicable rules, these may include a portion of rent, utilities, insurance, and other eligible expenses.
To qualify, you generally need to meet the relevant exclusive-use and regular-use tests, along with an applicable qualification requirement such as the principal-place-of-business test.
A qualifying home office may also affect the treatment of certain trips between your home and other business locations. Whether a trip qualifies as business transportation rather than commuting depends on the facts and applicable tax rules.
Eligible furniture, equipment, and computers used in the business may qualify for depreciation or other deductions, including Section 179 expensing where the requirements are met. These deductions are separate from the calculation of the home office deduction and may have their own limitations.
In the United States, eligible taxpayers generally use IRS Form 8829 to calculate home office expenses under the regular method when required. The simplified method follows a different reporting process. Confirm which forms and calculations apply to your return.
