You can generally write off lease payments as a business expense when the property is used in your trade or business, the payment is ordinary and necessary, and you have no ownership stake in the asset. Rent on office space, equipment, machinery, and vehicles all qualifies. Personal lease payments do not. The catch is that the IRS looks at what your agreement actually does, not what it’s called: a true lease gets a clean rent deduction, while an arrangement that functions like an installment purchase is treated as one and deducted through depreciation instead.
The Basic Rule
Section 162(a)(3) of the Internal Revenue Code allows a deduction for rental payments made to use property in your business, as long as you haven’t taken title and hold no equity in it.1Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses The payment must be both ordinary (common in your line of work) and necessary (appropriate and helpful for the business).2Internal Revenue Service. Fact Sheet FS-2007-14 – Deducting Rent and Lease Expenses
If the leased property does double duty, only the business share of the payment is deductible. A copier used 90% for business and 10% for personal projects yields a deduction of 90% of the lease payment. The same logic applies to vehicles and any other asset that crosses the line.
True Lease or Disguised Purchase
The label on the contract doesn’t control the tax treatment. If your deal functions as buying the property on installments, the IRS will treat it that way. The distinction matters because a true lease lets you deduct each payment in full as rent, while a disguised purchase forces you to capitalize the asset and recover its cost through depreciation over several years.
The IRS weighs factors drawn from Revenue Ruling 55-540, and no single factor decides the question.3Internal Revenue Service. Income and Expenses 7 Your agreement is more likely to be reclassified as a conditional sales contract if:
- Part of each payment builds an equity interest in the property.
- You get title after making all required payments.
- The amount you pay for a short period of use is a disproportionately large share of what buying the asset outright would cost.
- The payments significantly exceed the property’s fair rental value.
- You can buy the property at the end for a price that’s trivial next to what it will be worth then.
- Some portion of the payments is labeled as interest, or an interest component is easy to identify.
The more of these your agreement triggers, the stronger the IRS’s case that you’re really buying. Getting the classification wrong on audit can mean recalculated deductions, back taxes, and interest.
How the Deduction Works on a True Lease
When your agreement qualifies as a true lease, you deduct each periodic payment as a business expense in the year you pay it if you’re on the cash method, or the year the obligation accrues if you’re on the accrual method. Sole proprietors report the deduction on Schedule C. Partnerships and S corporations report it on the entity return, and the deduction flows through to the owners.
Common qualifying items include commercial real estate, office equipment, machinery, technology, and vehicles. Multiply the payment by the business-use percentage where the asset is also used personally.
Prepaying Rent
Cash-basis taxpayers sometimes prepay rent to pull the deduction into the current year. The IRS allows this only if the prepaid period doesn’t extend beyond 12 months after the date you first receive the benefit, or the end of the following tax year, whichever comes first. Prepaying 11 months of office rent in December generally works. Prepaying two years in a lump sum does not; you spread that deduction over the period it covers.
Early Termination Fees
A fee to break a business lease early is generally deductible in the year you pay it, since it doesn’t create a lasting asset. One exception: if the termination is part of a plan to acquire replacement property, the IRS may require you to capitalize the fee into the cost of the new property.
Vehicle Leases
Cars get extra scrutiny because they cross so easily between business and personal use. The IRS gives you two methods, and the one you choose in the first year of business use for a leased vehicle locks you in for the rest of the lease.4Internal Revenue Service. Business Use of Car
Standard Mileage Rate
The simpler option is the standard mileage rate, 72.5 cents per mile for business driving in 2026.5Internal Revenue Service. IRS Sets 2026 Business Standard Mileage Rate at 72.5 Cents Per Mile This rate covers fuel, insurance, maintenance, and use of the vehicle itself. If you pick this method for a leased car, you cannot separately deduct the lease payment; the mileage rate replaces it.6Internal Revenue Service. Income and Expenses 5
Actual Expense Method
The actual expense method lets you deduct every business-related cost of operating the vehicle, including fuel, insurance, repairs, registration, and the lease payment itself, multiplied by the business-use percentage.6Internal Revenue Service. Income and Expenses 5 It requires detailed records of every cost plus a mileage log to prove the split.
Lease Inclusion Amount for Expensive Vehicles
Lease a passenger vehicle with a fair market value above $62,000 at the start of the lease, use the actual expense method, and the IRS requires you to add a small “lease inclusion amount” to your gross income each year.7Internal Revenue Service. Rev. Proc. 2026-15 – Limitations on Depreciation Deductions for Passenger Automobiles The rule exists under Section 280F to keep lessees of luxury vehicles from getting a bigger tax break than buyers, who face annual depreciation caps.8Office of the Law Revision Counsel. 26 USC 280F – Limitation on Depreciation for Luxury Automobiles
You look up the dollar figure in the IRS table for the year the lease began, multiply it by your business-use percentage for the tax year, and report the result as income. The effect is a modest reduction in your net deduction. For a lease that starts in 2026, use the table in Rev. Proc. 2026-15, and keep using that same table for every year the lease runs.7Internal Revenue Service. Rev. Proc. 2026-15 – Limitations on Depreciation Deductions for Passenger Automobiles
If the IRS Treats Your Lease as a Purchase
Fail the true-lease analysis and the IRS reclassifies the deal as a conditional sales contract, treating you as owner of the asset from day one. The full periodic payment is no longer deductible as rent. Each payment splits into two pieces: an interest portion, deductible as business interest, and a principal portion, which is not deductible now. You recover the principal through depreciation on Form 4562.
MACRS Depreciation
Most business assets are depreciated under the Modified Accelerated Cost Recovery System. Computers, office equipment, and general-purpose vehicles fall into a 5-year class. Nonresidential real property uses 39 years.9Office of the Law Revision Counsel. 26 USC 168 – Accelerated Cost Recovery System
Section 179 and Bonus Depreciation
Section 179 lets you write off the full cost of qualifying property in the year it’s placed in service, rather than spreading it out. For tax years beginning in 2026, the statutory base deduction limit is $2,500,000, with a phase-out that begins when total qualifying property placed in service exceeds $4,000,000; both figures adjust for inflation.10Office of the Law Revision Counsel. 26 USC 179 – Election to Expense Certain Depreciable Business Assets Qualifying property includes equipment, machinery, off-the-shelf software, and certain interior improvements to nonresidential buildings.
On top of, or instead of, Section 179, qualifying property may be eligible for bonus depreciation under Section 168(k). The One Big Beautiful Bill Act permanently restored 100% bonus depreciation for qualifying property acquired and placed in service after January 19, 2025, with no phase-down.11Internal Revenue Service. Treasury, IRS Issue Guidance on the Additional First Year Depreciation Deduction Amended as Part of the One Big Beautiful Bill For assets pulled from lease treatment into purchase treatment in 2026, that can mean deducting the full cost basis in year one, a bigger upfront deduction than the lease payments would have delivered.
Improvements to Property You Lease
If you build out an office interior, install HVAC, or add security features to space you rent, those costs are yours to capitalize and depreciate. Interior improvements to nonresidential buildings placed in service after 2017 are qualified improvement property with a 15-year MACRS recovery period.12Internal Revenue Service. Publication 946 – How To Depreciate Property These improvements may also qualify for Section 179 expensing, and with 100% bonus depreciation permanent, the full cost may be deductible in year one.10Office of the Law Revision Counsel. 26 USC 179 – Election to Expense Certain Depreciable Business Assets You’re renting the space, but you deduct the cost of improving it.
Renting From Yourself or a Related Party
Leasing business property from yourself, a family member, or an entity you own is legal and common, and it draws close IRS attention. The rent must be at a fair market rate, meaning what unrelated parties would agree to for similar property. If the rent is inflated to shift income or pump up deductions, Section 482 gives the IRS broad authority to reallocate income among organizations, trades, or businesses controlled by the same interests.13Office of the Law Revision Counsel. 26 USC 482 – Allocation of Income and Deductions Among Taxpayers
Documentation is the best defense. A professional appraisal or independent market study showing comparable rental rates for similar properties in the area goes a long way on audit. The lease itself should include the terms you’d see in a third-party deal: maintenance responsibilities, insurance requirements, late-fee provisions, and regular rent invoicing.
Records You Need to Keep
The IRS can disallow your entire deduction if you can’t back it up. For listed property (vehicles, computers, cell phones, and similar assets prone to personal use), you must substantiate the amount, date, and business purpose of every expense.14eCFR. 26 CFR 1.274-5 – Substantiation Requirements Estimates don’t cut it; the IRS wants contemporaneous records made at or near the time of the expense.15Internal Revenue Service. Publication 463 – Travel, Gift, and Car Expenses
Keep the fully executed lease agreement, receipts or bank statements showing each payment, and correspondence about changes to the lease terms. For assets used partly for personal purposes, keep a log tracking business versus personal use.
Vehicle mileage logs are where deductions most often fall apart on audit. Every trip needs the date, the mileage driven, the destination, and the business purpose. “Drove to client” isn’t enough; name the client. GPS apps automate the tracking, but you still need to tag each trip with a purpose. Keep it current through the year. Reconstructing a log from memory at tax time is exactly the kind of record the IRS rejects, and the burden of proof sits entirely with you.
