The kitchen table is not a home office deduction. The IRS is painfully clear about this, and every January a freelancer discovers that exclusive use is a real test, not a vibe. If the kids do homework on the same desk, the den is a den. Publication 587 will not pretend otherwise.
To claim expenses for business use of your home, you generally must use a specific area exclusively and regularly as your principal place of business, or as a place to meet clients, or as a separate unattached structure used for the business. Exclusive use means that area is used only for the trade or business. The IRS example is an attorney whose family also uses the den for recreation: no deduction. That is the rule that kills most kitchen-table claims.
The home office deduction is a space test, not a laptop test
Regular use is the second gate. Incidental or occasional business use is not enough. Working from the couch on Thursdays does not convert the living room. A spare room with a door, a desk that is not a puzzle table, and a schedule that actually happens will have a much easier time.
Your home can still qualify as the principal place of business if you use it exclusively and regularly for administrative or management work and you have no other fixed location where you do substantial admin. Publication 587’s plumber, Sid, spends most days in customers’ houses, keeps a small exclusive home office for calls, books, and ordering, and still qualifies. The office is allowed to be the back office. It is not allowed to be the guest room on weekends.
Employees generally cannot take this deduction under current rules. This article is for people filing a Schedule C, a Schedule F, or certain partners with unreimbursed expenses required by the partnership agreement. If you are a W-2 remote worker, do not copy a blog post from 2019.
Simplified method versus actual expenses
The simplified method is $5 per square foot, capped at 300 square feet. That is a $1,500 ceiling, and you choose it year by year on a timely original return. You cannot also deduct actual home expenses or depreciation for that same space in a simplified year. You can still deduct business costs that are not about the house: software, supplies, equipment.
Actual expenses mean Form 8829, a business percentage (square footage or rooms), and a split between direct costs (paint only in the office) and indirect costs (a slice of utilities, insurance, rent). Depreciation of the business portion of a home you own is 39-year nonresidential real property. It also reduces basis and can follow you at sale: you cannot exclude gain equal to depreciation allowed or allowable after May 6, 1997. That is the part Instagram never mentions.
Gross-income limits apply. You cannot use home-office expenses to create a home-office loss against other income in the way people hope. Disallowed amounts may carry forward if you use actual expenses. They do not get used in a simplified year.
How to make the space actually qualify
- Pick a separately identifiable area. A room is easiest. A marked-off corner can work; a couch cannot.
- Stop using it for movies, guest beds, and homework. Exclusive means exclusive.
- Use it on a real schedule. Photos of a desk are not regular use.
- Measure. 10 by 12 is 120 square feet. Simplified deduction: 120 × $5 = $600.
- Keep the records Publication 587 asks for: the space, the exclusive regular use, and the expenses.
Storage of inventory is a narrow exception to exclusive use if you sell products, the home is the only fixed location, and the space is a separately identifiable storage area used regularly. Daycare has its own exception and time-allocation math. Do not import those exceptions into a consulting business because a podcast said “write off the house.”
A deduction is not a design project
The home office deduction rewards a boring, dedicated room and punishes a lifestyle brand of working everywhere. That is slightly annoying and completely fair. If you want the tax item, give the work a door. If you want the couch, enjoy the couch and stop calling it a loophole.
