What this deduction is
The home office deduction lets eligible self-employed people deduct part of their housing expenses if they use part of their home regularly and exclusively for business.
In plain English: if you run your business from home, the IRS may let you write off a percentage of expenses like rent, mortgage interest, utilities, internet, insurance, and repairs.
This deduction exists because part of your home is functioning as a business workspace instead of purely personal living space.
Who qualifies
✓ Usually Qualifies
Freelancers, gig workers, sole proprietors, independent contractors, online business owners, consultants, creators, and other self-employed people who use part of their home for business.
✕ Usually Does Not
Most W-2 employees working remotely cannot claim the federal home office deduction under current tax law, even if their employer requires remote work.
📍 The two key IRS rules
Your home office must be used regularly and exclusively for business. A kitchen table used for both dinner and work usually does not qualify. A dedicated office area used only for business usually does.
What counts as a home office
What the IRS is actually looking for
The IRS mainly wants to know whether part of your home is genuinely functioning as a business workspace.
Exclusive use — The space is only used for business, not personal activities.
Regular use — You use the space consistently, not occasionally.
Principal place of business — The home office is your main place for managing or operating the business.
Separate structure — A detached garage, studio, or workshop can qualify if used for business.
Storage exception — Inventory storage may qualify even without exclusive use in limited situations.
Daycare exception — Licensed daycare providers have special rules allowing partial personal use.
Two ways to calculate it
The IRS gives you two methods for calculating the deduction:
Simplified method — Deduct $5 per square foot of office space, up to 300 square feet (maximum $1,500 deduction).
Actual expense method — Deduct the business percentage of actual home expenses like rent, utilities, insurance, repairs, and depreciation.
✓ Simplified Method
Faster, easier, lower audit risk, and requires less recordkeeping. Best for smaller offices or simple businesses.
↑ Actual Expense Method
More paperwork but can create a much larger deduction if your housing costs are high or your office takes up significant square footage.
Expenses that may qualify
Depending on the method used, these expenses may partially count toward the deduction:
Rent — Apartment or home rental payments
Mortgage interest — Interest portion of home loan payments
Property taxes — State and local real estate taxes
Internet — Business-use portion of internet service
Home insurance — Business percentage of homeowners or renters insurance
Repairs and maintenance — Especially repairs directly affecting the office
Depreciation — Gradual write-off of part of the home's value for owners using the actual method
Common mistakes to avoid
⚠ Mixed Personal Use
The biggest mistake is using the space for both personal and business purposes. A guest room with a desk usually fails the exclusive-use rule.
⚠ Claiming Remote Work
Many W-2 employees assume remote work automatically qualifies them. For most employees, the federal deduction was suspended after 2017.
⚠ Bad Square Footage Math
Guessing office size instead of measuring can inflate deductions and create audit problems later.
⚠ No Documentation
Keep utility bills, lease agreements, mortgage statements, repair receipts, and photos of the workspace in case the IRS asks questions.
What to do right now
If you're self-employed and work from home regularly, measure your office space and compare the simplified deduction versus the actual expense method before filing. Many small business owners automatically use the simplified method when the actual method would save them significantly more money. If you own your home, have high housing costs, or operate a larger business from home, it's worth having a CPA calculate both approaches.
Questions to ask your tax professional
01
Should I use the simplified method or actual expense method this year?
02
Does my workspace actually satisfy the exclusive-use rule?
03
Which home expenses can I legally allocate to the business?
04
Will taking depreciation affect taxes when I eventually sell my home?

Are there state-level home office deductions available where I live?
06
What records should I keep in case of an IRS audit?
Frequently asked questions
Can I claim the deduction if I work from my couch sometimes?
Usually no. The IRS generally requires a dedicated business area used exclusively for work. Casual or flexible work locations inside the home normally do not qualify.
Does a spare bedroom office qualify?
Yes — if the room is used regularly and exclusively for business. If it doubles as a guest room or personal storage room, that can disqualify the deduction.
Can renters take the home office deduction?
Yes. Renters can deduct the business-use percentage of rent and certain other housing expenses if they qualify.
Is taking the home office deduction an audit trigger?
Not automatically. The deduction is extremely common among self-employed taxpayers. Problems usually happen when people exaggerate office size, ignore the exclusive-use rule, or claim personal expenses as business costs.
Where is the deduction reported?
Most self-employed taxpayers claim the deduction through Schedule C and Form 8829, although the simplified method may not require Form 8829.
