Home Office Deduction

Who qualifies (and who doesn't)

The home office deduction is for people who work for themselves. That means self-employed individuals, 1099 contractors, freelancers, gig workers, and small business owners. If you file a Schedule C (or operate through a partnership or S-corp), you're in the right camp.

W-2 employees? You're out of luck — at least for federal purposes. The Tax Cuts and Jobs Act of 2017 suspended unreimbursed employee business expenses through 2025, and the home office deduction falls squarely in that bucket. Even if your employer requires you to work from home, even if you have a dedicated office with a door that locks, you can't deduct it on your federal return. Some states still allow it (California, New York, and a handful of others), so check your state rules.

Remote workers who get a W-2 — this is the most common point of confusion. 64% of remote workers think they qualify for the home office deduction, but almost none of them do. If your employer gives you a W-2, it's not deductible. If they give you a 1099, it is.

The two tests: exclusive use + regular use

The IRS imposes two requirements, and both have to be met:

Exclusive use

The space must be used only for business. Not "mostly." Not "during the day." Exclusively. A desk in the corner of your bedroom doesn't count if you also sleep there. A laptop at the kitchen table doesn't count if your kids eat breakfast at it. This is the test that trips people up — and the one the IRS asks about first in an audit.

The space doesn't need to be a separate room with four walls and a door. It can be a clearly defined portion of a room — say, a 120 sq ft section of your basement that's cordoned off and used only for work. What matters is that the area is identifiable and nobody uses it for anything else.

Regular use

You use the space on a continuing basis — not just once a month when you need to catch up on invoices. If your home office is where you do the bulk of your administrative work (billing, client calls, project planning), that counts even if you do the "real" work elsewhere. A contractor who builds houses on-site but does all the paperwork, ordering, and client communication from a home office still qualifies.

There's also the principal place of business test. If you see clients or customers at your home — say, a therapist who sees patients in a home office, or a piano teacher who gives lessons there — you meet the test even if you also work elsewhere.

Simplified method

The simplified method is exactly what it sounds like. You multiply your office square footage by $5, up to a maximum of 300 square feet. That gives you a deduction between $0 and $1,500. No receipts, no depreciation schedules, no utility bills — just measure the room and do the math.

The trade-off is that the simplified method caps out at $1,500. For a small apartment office, that might be competitive with the regular method. For a larger space with high rent or a mortgage, the regular method usually wins. The simplified method also means you can't deduct any other home-related expenses — no separate utility write-off, no depreciation. It's all-or-nothing.

One underrated benefit: lower audit risk. The simplified method creates a simple paper trail. You measure the room, do basic multiplication, and that's it. IRS agents spend less time scrutinizing $900 deductions supported by a single measurement than $4,300 deductions supported by 12 months of utility bills, property tax statements, and a depreciation calculation.

You can switch between methods year to year. Use simplified in 2025 if you don't want the hassle, then switch to regular in 2026 if your expenses spike.

Regular method

The regular method is more work — sometimes a lot more work — but typically produces a larger deduction. Here's the formula: figure out what percentage of your home is used for business, then apply that percentage to your actual home expenses.

Step-by-step calculation

Start with square footage. Say you have a 2,000 sq ft home and a 200 sq ft office that passes the exclusive-use test. That's 10% business use.

Now tally your annual home expenses:

• Rent: $24,000 (or mortgage interest: $15,600)
• Utilities (electric, gas, water, internet): $3,600
• Homeowners/renters insurance: $1,200
• Repairs that affect the whole home: $800
• Property taxes: $4,000

Total: $33,600 in housing costs. Apply the 10% business-use percentage: $3,360 deduction.

That's more than double the simplified method's max of $1,500 — and this is for a modest 200 sq ft office. A larger space or higher-cost area widens the gap further. This is why the regular method is worth the paperwork for most people who own a home or pay significant rent.

One important distinction: if you own your home, you can also depreciate the business portion. That adds another layer to the deduction. But depreciation is a double-edged sword — it comes back when you sell (see the recapture section below). If you rent, you deduct a percentage of your rent instead. No depreciation complication.

Direct vs indirect expenses

Home office expenses fall into two buckets:

Direct expenses are costs that only benefit the office itself. Painting the office walls, repairing a window in that room, installing a dedicated AC unit — these are 100% deductible. No need to apply the business-use percentage.

Indirect expenses benefit the whole home and are deductible at the business-use percentage. This is where rent, mortgage interest, utilities, insurance, security systems, and general repairs land. Roof replacement? It benefits the whole house, so only the business percentage is deductible.

Landscaping is where things get tricky. The IRS generally says no — landscaping doesn't relate to the business use of the home office unless you regularly meet clients there and the landscaping is part of maintaining a professional appearance. Most home office filers skip it.

Daycare exception

If you run a licensed daycare out of your home, the exclusive-use requirement doesn't apply. Daycare spaces are used for personal purposes when the kids go home — and the IRS knows that. Instead of exclusivity, you calculate the business-use percentage based on time: how many hours per day and days per year the space is used for daycare versus personal use.

Say a 400 sq ft playroom is used for daycare 10 hours a day, 5 days a week, 50 weeks a year. That's 2,500 hours of business use out of 8,760 total hours in a year — about 28.5%. If total home expenses are $30,000, plus $300 in direct daycare expenses, the deduction works out to roughly $8,850. The simplified method is also available for daycare providers at the same $5/sq ft rate, capped at 300 sq ft.

Depreciation recapture when you sell

Here's the part nobody tells you about until it's too late. If you use the regular method and depreciate your home office, the IRS remembers. When you sell the house, that depreciation gets "recaptured" — taxed as ordinary income (capped at 25%), regardless of whether you actually took the depreciation deduction or just could have.

Let's say you claimed a home office for 5 years and depreciated $12,000 total. When you sell, that $12,000 gets taxed at up to 25% — a potential $3,000 tax bill you didn't see coming. The $250,000/$500,000 home sale exclusion (for primary residences) doesn't shield depreciation recapture.

Does this mean you should avoid the regular method? Not necessarily. The annual tax savings often outweigh the eventual recapture — especially if you're in a high bracket now and expect to be in a lower one later, or if you plan to stay in the house a long time. But it's a factor worth running numbers on before you commit. The simplified method avoids depreciation entirely, so there's no recapture to worry about.
