A home office deduction is a federal tax deduction for certain costs of using part of a home for business. It reduces taxable business income. It is not a dollar-for-dollar tax credit or refund.
The deduction is generally available to freelancers, independent contractors, sole proprietors and some partners who use part of their home regularly and exclusively for business. W-2 employees who work remotely generally cannot claim the federal home office deduction. (IRS)
The IRS's Publication 587 for 2025 returns filed in 2026 provides the detailed federal rules. The simplified method uses $5 per square foot, up to 300 square feet.

Who Qualifies for the Home Office Deduction?
You generally qualify when you use part of your home in connection with a trade or business and the space meets one of the IRS tests.
The space must usually be used:
- Exclusively and regularly as your principal place of business
- Exclusively and regularly to meet or deal with clients, customers or patients
- Regularly for business in a separate structure, such as a detached garage or studio
- Regularly to store inventory or product samples in a qualifying business
- As a qualifying daycare facility
A home office can be your principal place of business when you conduct administrative or management activities there and have no other suitable fixed location for those activities. You may also qualify if you regularly meet clients or customers at home, even when the business operates elsewhere. (IRS)
What Does "Exclusive Use" Mean?
Exclusive use generally means that the business area is used only for business. A spare bedroom used as both a guest room and an office usually does not qualify for the regular home office deduction.
The IRS has exceptions for certain inventory-storage arrangements and daycare operations. (IRS)
Which Home Expenses Can You Deduct?
The treatment of a home expense depends on whether it applies only to the office or to the entire home.
| Expense type | General treatment |
|---|---|
| Direct expense | Usually 100% deductible when it benefits only the business area |
| Indirect expense | Deductible according to the business-use percentage |
| Personal expense | Not deductible as a business expense |
Direct Expenses
Direct expenses apply only to the office area. Examples include:
- Painting or repairing the office
- Installing a business-specific improvement in the office
- Repairing damage limited to the business space
Direct expenses are generally deductible in full, subject to the home office deduction limit. (IRS)
Indirect Expenses
Indirect expenses benefit the entire home. Depending on the method you use, you may deduct the business-use portion of expenses such as:
- Rent
- Utilities
- Homeowners insurance
- General repairs and maintenance
- Security-system costs
- Mortgage interest and real estate taxes, subject to the applicable rules
- Depreciation, when you own the home and use the regular method
If the office represents 10% of the home, you may generally allocate 10% of qualifying indirect expenses to business use.
Homeowners cannot deduct the fair rental value of the home. Renters may generally deduct the business-use percentage of rent when they otherwise qualify. (IRS)
How Do You Calculate the Deduction?
The IRS provides two methods: the simplified method and the regular method.
Simplified Method
The simplified method uses a standard rate of $5 per square foot, with a maximum of 300 square feet. The maximum deduction is therefore $1,500.
Example:
- Business-use area: 150 square feet
- 150 × $5 = $750 deduction
This method does not require you to calculate actual home expenses or depreciation for the office. Expenses above the business-use limit cannot be carried forward under the simplified method. (IRS)
Regular Method
The regular method uses actual expenses. You calculate the percentage of the home used for business and apply that percentage to qualifying indirect expenses.
Example:
- Home office: 200 square feet
- Total home: 2,000 square feet
- Business-use percentage: 10%
- Annual utilities: $3,000
- Business-use portion: $3,000 × 10% = $300
A direct office repair may be deductible in full. Ten percent of qualifying whole-home costs may also be deductible.
The regular method may produce a larger deduction, but it requires more records. If you own the home, the calculation may also include depreciation. (IRS)
Should You Use the Simplified or Regular Method?
| Factor | Simplified method | Regular method |
|---|---|---|
| Calculation | $5 per square foot | Actual qualifying expenses |
| Maximum | $1,500 | No fixed dollar cap, but limitations apply |
| Recordkeeping | Easier | More detailed |
| Depreciation | Not claimed for the home office | May be claimed when applicable |
| Carryover | No excess deduction carryover | Some disallowed expenses may carry forward |
| Best suited to | Small, simple home offices | Larger offices or higher home expenses |
You can choose a method for each tax year. The simplified method may be convenient for a small office. The regular method may produce a larger deduction when the business-use percentage or home expenses are higher. (IRS)
Is the Home Office Deduction Limited?
Yes. The deduction generally cannot create or increase a business loss.
Under the regular method, the IRS limits certain home office expenses based on the gross income from the qualified business use of the home after certain other business expenses are deducted. Expenses disallowed by the limit may generally carry forward to a later year.
The simplified method does not allow that carryover. (IRS)
Where Do You Claim the Deduction?
A self-employed taxpayer who files Schedule C, Profit or Loss From Business, generally reports the home office deduction on Schedule C, line 30. Form 8829 is used to calculate the deduction when required under the regular method.
Partners, farmers and daycare providers may use different forms or worksheets. (IRS)
What Records Should You Keep?
Keep records supporting both your eligibility and the amount claimed, including:
- The dimensions and total area of the home
- A floor plan or calculation of the business-use percentage
- Utility, rent, insurance, repair and mortgage records
- Receipts for direct office expenses
- The date business use began
- Purchase, improvement and depreciation records if you own the home and use the regular method
For a self-employed taxpayer, the choice usually comes down to convenience versus the size of the deduction. Compare the $5-per-square-foot method with the regular method using your actual expenses. If you are a W-2 employee working from home, remote work alone generally does not qualify you for the federal deduction.
