Can I Deduct Home Office Expenses?
Updated for tax year 2025 (filed in 2026) · IRS-sourced
If you use part of your home exclusively and regularly for business, you may qualify for the home office deduction. This deduction is available to self-employed individuals and independent contractors — but not W-2 employees.
Self-employed? You can deduct home office expenses using the simplified method ($5/sq ft, max $1,500) or the regular method (actual expenses). W-2 employee? You cannot claim this deduction on your federal return.
Who Qualifies for the Home Office Deduction?
To claim the home office deduction, you must meet both of these requirements:
Regular and exclusive use: You must use a specific area of your home exclusively for conducting business on a regular basis. Occasional or incidental business use does not qualify.
Principal place of business: Your home office must be your principal place of business, or a place where you regularly meet clients or patients, or a separate structure used for business (like a detached garage or studio).
Since the Tax Cuts and Jobs Act (TCJA) of 2017, W-2 employees cannot deduct home office expenses on their federal tax return, even if their employer requires them to work from home. This applies through at least tax year 2025.
Two Methods to Calculate Your Deduction
Simplified Method
| Detail | Amount |
|---|---|
| Rate per square foot | $5.00 |
| Maximum square footage | 300 sq ft |
| Maximum annual deduction | $1,500 |
The simplified method is easy: multiply the square footage of your home office (up to 300 sq ft) by $5. No need to track individual expenses or calculate depreciation.
Regular Method (Actual Expenses)
With the regular method, you deduct actual expenses based on the percentage of your home used for business. Deductible expenses include:
Mortgage interest or rent, utilities (electricity, gas, water, internet), homeowners insurance, repairs and maintenance to the office area, depreciation of the home, and real estate taxes.
To calculate the business percentage, divide the square footage of your office by the total square footage of your home. For example, a 200 sq ft office in a 2,000 sq ft home = 10% business use.
Which Method Should I Choose?
The simplified method is best if your home office is 300 sq ft or less and you want minimal recordkeeping. The regular method often yields a larger deduction if you have significant housing expenses or a larger office space, but requires tracking all expenses and potentially calculating depreciation.
You can switch methods from year to year, but you must be consistent within a single tax year.
Frequently Asked Questions
Can I deduct internet and phone bills?
Yes, under the regular method. You can deduct the business-use percentage of your internet and phone bills. If you use your internet 60% for business, you can deduct 60% of the cost.
Does a home office trigger an audit?
Not by itself. The IRS audits based on overall return characteristics, not individual deductions. However, keeping thorough records and meeting the exclusive-use test will protect you if questioned.
What form do I use?
Report the home office deduction on Form 8829 (Expenses for Business Use of Your Home) if using the regular method, or directly on Schedule C line 30 if using the simplified method.
