Working from home has become standard for millions of Americans, but many people who qualify for the home office deduction never claim it. Either they do not know it exists, think it will trigger an audit, or find the rules confusing. This guide cuts through the confusion and explains exactly how the deduction works, who qualifies, how to calculate it, and what records to keep.
Who Can Claim the Home Office Deduction?
The home office deduction is available to self-employed individuals and small business owners who use part of their home for business. As of 2026, employees who work from home — including remote workers — cannot claim this deduction on their federal return. The Tax Cuts and Jobs Act of 2017 suspended the deduction for employees through 2025, and no legislation has reinstated it.
Qualifying taxpayers include:
- Sole proprietors (Schedule C filers)
- Freelancers and independent contractors
- Partners in a partnership who use home office space for partnership work
- S-corporation shareholders who perform services for the corporation from home (requires an accountable plan)
- Self-employed individuals in any field
The Two Requirements: Regular and Exclusive Use
To claim the deduction, the area of your home used for business must meet two tests.
Regular Use
You must use the area for business on a regular basis. Occasional or incidental use does not qualify. If you use a room for client calls every week, that is regular use. If you occasionally open your laptop at the kitchen table, that is not.
Exclusive Use
The business area must be used exclusively for business. A dedicated office used only for work qualifies. A guest bedroom with a desk in the corner that you also use when family visits does not. The IRS interprets “exclusive” strictly: any personal use disqualifies the area.
There are two exceptions to the exclusive use rule:
- If you store inventory or product samples at home for a business that has no other fixed location, the storage area qualifies even if you also use it personally.
- If you operate a licensed day care facility in your home, the day care area qualifies even if used for other purposes after day care hours, with a time-based proration.
Principal Place of Business
Your home office must be your principal place of business, OR a place where you regularly meet clients or customers, OR a separate structure not attached to your home. Most freelancers and home-based business owners satisfy the “principal place of business” test.
If you have multiple locations — say, a rented studio and a home office — your home office can still qualify if you use it regularly and exclusively for administrative and management tasks, provided you do not conduct those activities at your other location.
Two Calculation Methods
The IRS offers two methods for calculating the home office deduction: the simplified method and the regular (actual expense) method.
The Simplified Method
Multiply the square footage of your home office by $5 per square foot. The maximum you can claim under this method is 300 square feet, making the maximum deduction $1,500 per year.
Example: A 200 square foot dedicated home office. Deduction = 200 x $5 = $1,000.
The simplified method requires no recordkeeping beyond knowing the square footage, and it does not affect your home’s depreciation for future sale purposes. The downside is a lower deduction if your actual expenses are high.
The Regular (Actual Expense) Method
Under this method, you calculate the business-use percentage of your home and apply it to actual home expenses. This requires more recordkeeping but typically produces a larger deduction.
Calculate business-use percentage by dividing the square footage of your office by the total square footage of your home. A 200 square foot office in a 2,000 square foot home gives you a 10% business-use percentage.
Apply that percentage to qualifying home expenses:
- Rent (if you rent)
- Mortgage interest
- Real estate taxes
- Homeowners or renters insurance
- Utilities (electricity, gas, water)
- Home repairs and maintenance (for the whole home)
- Depreciation (for homeowners)
Some expenses — repairs that exclusively benefit the home office, for example — can be deducted 100% without applying the percentage.
Depreciation for Homeowners
If you own your home, you can deduct the business-use portion of depreciation. This is calculated using the adjusted basis of your home (generally cost minus land value), depreciated over 39 years (the IRS period for nonresidential real property).
Depreciation is a significant deduction — potentially thousands of dollars per year. However, it comes with an important caveat: when you sell your home, the depreciation you claimed for the home office may be recaptured and taxed at up to 25% as unrecaptured Section 1250 gain. The tax savings during the years you claim the deduction typically outweigh this future recapture, but it is worth understanding.
Home Office Deduction Limitation
Under the actual expense method, your home office deduction cannot exceed the gross income from your business. In other words, the deduction cannot create a net loss on Schedule C. Any disallowed deduction due to the income limit carries forward to next year.
The simplified method has the same income limitation.
How to Claim the Deduction
Self-employed individuals claim the home office deduction on Form 8829 (Expenses for Business Use of Your Home), which attaches to Schedule C. The simplified method can be claimed directly on Schedule C without Form 8829.
On Form 8829, you enter:
- Square footage of your home office and your total home
- Gross income from Schedule C (for the limitation calculation)
- Your actual home expenses (rent or mortgage interest, insurance, utilities, repairs, depreciation)
The form walks you through the calculation and produces the allowable deduction, which carries back to Schedule C.
Recordkeeping Requirements
To claim the actual expense method, keep records of:
- The square footage of your office and total home (measure them yourself or use your home purchase documents)
- All home-related expenses: mortgage statements or rent receipts, utility bills, insurance premiums, repair invoices
- Photos of your dedicated office space
- If you have clients visit, a log of meetings held at your home office
You do not need to submit these records with your return, but you must be able to produce them if the IRS questions the deduction.
Does the Home Office Deduction Trigger Audits?
This is a persistent myth that discourages many legitimate claimants. The home office deduction does not have a special audit trigger. The IRS uses statistical models to identify returns that look unusual given income level and industry. A reasonable, well-documented home office deduction on a Schedule C is not unusual — millions of self-employed people claim it every year.
What does increase scrutiny: deducting a disproportionately large home office (claiming 40% of a home as office space when the business generates modest income), deducting personal expenses, or taking the deduction without any actual business activity. Follow the rules, keep records, and claim what you legitimately qualify for.
Choosing Between Simplified and Actual Expense Methods
The simplified method wins on simplicity but loses on deduction size for anyone with a meaningful home expense burden. Here is a rough comparison:
Simplified: 200 sq ft x $5 = $1,000 deduction
Actual: 10% business use on $30,000 in annual home expenses (rent $18,000, utilities $3,600, insurance $1,200, etc.) = $3,000 deduction
In most cases where rent or mortgage costs are significant, the actual expense method produces a larger deduction. Run the numbers both ways before choosing. You can switch methods from year to year.
State Tax Treatment
Most states that have an income tax conform to the federal home office deduction rules, meaning the same deduction applies to your state return. A few states have their own rules or do not allow certain expenses (California, for instance, does not allow the depreciation of home office space). Check your state’s specific guidance or consult a tax professional familiar with your state.
Common Mistakes to Avoid
Claiming a room that is not exclusively used for business is the most common error. “I mostly work in there” is not exclusive use. The space must be truly dedicated to business.
Forgetting to track actual expenses throughout the year forces you to use the simplified method or reconstruct records at tax time. Set up a system to capture these expenses monthly.
Not carrying forward disallowed deductions. If the income limitation prevents you from deducting the full amount this year, the carryforward is real money — do not lose track of it.
Skipping depreciation as a homeowner. Depreciation is required (not optional) under the actual expense method once you claim it. Even if you do not take it, the IRS may treat the home sale gain as if you did. Claim it.
Key Takeaways
- Self-employed individuals can claim the home office deduction; employees generally cannot (as of 2026).
- The office must be used regularly and exclusively for business.
- The simplified method ($5/sq ft, max $1,500) is easier but often smaller.
- The actual expense method yields a larger deduction and requires Form 8829.
- Keep records of home expenses and office square footage.
- The deduction cannot exceed your business gross income; excess carries forward.
