Is Office Furniture Tax Deductible? 4 Ways to Write It Off

Office furniture is tax deductible when you buy it for a trade or business, and the tax code gives you four ways to write it off: an immediate deduction under the de minimis safe harbor, full expensing under Section 179, 100% bonus depreciation, or MACRS depreciation spread across seven years. One important limit before you go any further: if you’re a W-2 employee buying your own desk or chair, federal law bars you from claiming any of these deductions on your personal return.

Who Can Actually Claim It

The deduction for ordinary and necessary business expenses covers furniture like desks, chairs, filing cabinets, and bookshelves.¹ Sole proprietors, freelancers, partnerships, LLCs, S corporations, and C corporations can all claim it for furniture used in operations.

W-2 employees cannot. The Tax Cuts and Jobs Act eliminated the deduction for unreimbursed employee business expenses starting in 2018, and the One Big Beautiful Bill Act made that elimination permanent. Even if your employer requires you to furnish your home office, there is no federal deduction available to you. Your only path to recovering the cost is reimbursement from your employer through an accountable plan, which puts the deduction on the employer’s books instead of yours.

What Counts as Deductible Furniture

Two tests apply. The expense must be ordinary, meaning common in your line of work, and it must be necessary, meaning helpful and appropriate for the business.¹ A desk for an accounting practice clears that bar easily. A $4,000 massage chair in a software developer’s office is harder to defend.

The furniture must also be used for business. If a piece serves both work and personal purposes, only the business portion is deductible. A desk you use 70% for client work and 30% for personal browsing yields a 70% deduction. The IRS accepts any reasonable method for calculating the split, but “reasonable” means documented, not reconstructed from memory at tax time.²

Furniture in a dedicated commercial office almost always qualifies at 100% because the space itself is used entirely for business. Furniture in a home office is where the rules tighten.

Home Office Furniture

The room where the furniture sits must be used exclusively and regularly as your principal place of business, a place where you meet clients, or a separate structure used for your work.³ A spare bedroom converted into a full-time office qualifies. A dining room table you occasionally use for invoicing does not.

The exclusive-use rule is strict. If your kids do homework at your office desk on weekends, the IRS treats that as personal use, and your deduction for furniture in that room is at risk. The only statutory exception is for taxpayers running a licensed day care from their home.³

To calculate the business percentage of your home, divide the office’s square footage by the home’s total square footage, or divide the number of rooms used for business by the total room count if the rooms are roughly the same size.² That percentage applies to shared household costs like utilities and rent. For furniture that sits exclusively in your office and is used only for work, though, you deduct the full cost rather than a fractional share.

If you take the simplified home office deduction ($5 per square foot, up to 300 square feet), you can still separately depreciate or expense office furniture under Section 179. The simplified method only covers the space-related portion of the home office deduction.²

Four Ways to Write It Off

The right method depends on the price, your total equipment purchases for the year, and how much income you need to offset.

De Minimis Safe Harbor

For smaller items, the de minimis safe harbor lets you deduct purchases costing $2,500 or less per invoice or per item in the year you buy them.⁴ Businesses with audited financial statements (what the IRS calls an “applicable financial statement”) can use a $5,000 threshold.⁵ You elect this treatment by attaching a statement to your return for the year the expense is paid. It’s the simplest path for a desk lamp, a bookshelf, or a single chair.

Section 179 Expensing

For pricier furniture, Section 179 lets you deduct the full cost in the year you place the item in service. For tax years beginning in 2026, the maximum Section 179 deduction is $2,560,000, phasing out dollar-for-dollar once total qualifying property purchases exceed $4,090,000.⁶ Furniture alone rarely pushes a business near either ceiling.

Section 179 has a catch: the deduction can’t exceed your taxable business income for the year. If your business earns $30,000 and you buy $40,000 in furniture, you can only deduct $30,000 under Section 179, and the remaining $10,000 carries forward. Furniture converted from personal use to business use doesn’t qualify for Section 179, though it can still be depreciated under MACRS.

Bonus Depreciation

The One Big Beautiful Bill Act permanently restored 100% bonus depreciation for qualifying property acquired after January 19, 2025.⁷ Office furniture has a seven-year recovery period, well within the 20-year limit, so it qualifies.⁸

Two differences from Section 179 matter. There is no taxable income limitation, so bonus depreciation can create or increase a net operating loss. And it applies automatically unless you elect out. If you’d rather spread deductions across several profitable years, you have to affirmatively choose a reduced rate or opt out on your return for the year the furniture is placed in service.

MACRS Depreciation Over Seven Years

If you skip the immediate expensing options, the default is the Modified Accelerated Cost Recovery System. Office furniture is seven-year property.⁹ Under MACRS, the cost actually stretches across eight tax years because the half-year convention treats the furniture as placed in service at the midpoint of the first year, leaving a partial deduction in year eight. Publication 946 provides the exact percentages for each year.¹⁰

One timing rule catches people out: if more than 40% of your total depreciable property for the year is placed in service during the last three months, you must use the mid-quarter convention instead of the half-year convention, and the first-year deduction shrinks.¹¹ Check this before a big late-year purchase.

What If You Lease Instead of Buy

Lease payments on office furniture are deducted as rent in the year paid, with no depreciation schedule to track. The IRS will reclassify the arrangement as a conditional sale, however, if it has features that look more like a purchase: a bargain buy-out option, payments that build equity, total costs well above fair rental value, or an option to buy for a nominal amount at the end.¹² A $1 end-of-term buyout will almost certainly get the whole deal treated as a purchase, meaning you capitalize and depreciate instead of expensing the payments.

How to Report It

Form 4562 is where depreciation, Section 179, and bonus depreciation get reported.¹³ Section 179 goes in Part I. Bonus depreciation (Special Depreciation Allowance) goes in Part II. Standard MACRS depreciation for office furniture goes on line 19c in Part III, the row for seven-year property.¹⁴ You’ll enter the date placed in service, cost basis, recovery period, and business-use percentage.

Where Form 4562 attaches depends on your business structure:

Sole proprietors attach Form 4562 to Schedule C (Form 1040).¹⁵
Partnerships attach it to Form 1065, and the Section 179 deduction passes through to individual partners on Schedule K-1 rather than being claimed at the partnership level.¹⁴
S corporations attach it to Form 1120-S, with the Section 179 deduction flowing through to shareholders on Schedule K-1.¹⁴
C corporations attach it to Form 1120.

For de minimis safe harbor items, Form 4562 isn’t required. Deduct the cost on the appropriate expense line of your return, typically the “Other expenses” line on Schedule C for sole proprietors.

Watch Out for Recapture When You Sell

If you sell, trade, or scrap office furniture you previously wrote off, you may owe tax on part of what you deducted. Office furniture is Section 1245 property. When you sell it for more than its depreciated value, the gain attributable to prior depreciation is taxed as ordinary income rather than at the lower capital gains rate. You report the transaction on Form 4797.¹⁶

A separate recapture rule applies to Section 179 property. If the business use of the furniture drops to 50% or below before the end of the seven-year recovery period, you must report the recaptured Section 179 benefit as other income on your return.¹⁴ The same rule applies to bonus depreciation previously claimed. So if you wrote off $5,000 for a standing desk under Section 179 and sell it three years later for $2,000, you owe ordinary income tax on that $2,000 because it represents recovery of previous deductions.

Records to Keep

Save receipts or digital invoices showing the purchase price, vendor, and date for every piece of furniture you deduct. Document the date each item was placed in service, which is when it became available for business use and may differ from the purchase date. Shipping and assembly fees are part of the cost basis, so keep those receipts too.¹⁰

For mixed-use furniture, keep a log showing how you calculated the business-use percentage. The IRS accepts any reasonable method, but “reasonable” means contemporaneous documentation, not a back-of-the-envelope figure built during an audit.

The general retention rule is three years from the date you filed. Depreciated furniture needs longer. Because the recovery period runs seven years, keep records for at least three years after the final year you claim depreciation on the item. If you underreport income by more than 25%, the IRS has six years to audit, so longer retention is safer.¹⁷ Electronic records are fine as long as your system can produce legible copies on demand.

Penalties if You Get It Wrong

If the IRS disallows your deduction and finds you underpaid, the accuracy-related penalty is 20% of the underpayment when it stems from negligence or a substantial understatement of income tax. For a gross valuation misstatement, the penalty doubles to 40%.¹⁸ The mistakes that most often trigger these penalties are deducting furniture used primarily for personal purposes, claiming the full cost of mixed-use furniture without documenting the business percentage, and deducting home office furniture without meeting the exclusive-use test. Thorough records are the best defense against all three.
