To lease a car under your business, the company itself signs the contract using its Employer Identification Number and financial records, the vehicle is titled and registered in the business name, and the lease payments become a company expense. In practice, if the business is young or has a thin credit file, the lessor will still ask you to sign a personal guarantee, so your own credit and assets remain on the hook until the lease ends.
One thing to know upfront: business-purpose leases are excluded from the federal Consumer Leasing Act (Regulation M), regardless of the vehicle’s price.1Federal Reserve Board. Consumer Leasing The standardized fee and penalty disclosures you’d get on a personal lease aren’t required here. Read the contract line by line, and negotiate protections that a consumer deal would give you automatically.
Documents the Business Needs Before Applying
Have the full package ready before you walk into a dealership’s fleet department or a commercial leasing company. Missing paperwork stalls underwriting and can cost you the terms you were quoted.
- Employer Identification Number (EIN). The nine-digit number the IRS assigns through Form SS-4. Lessors use it to confirm the entity exists and to pull commercial credit. If you don’t have one, you can apply through the IRS website.2Internal Revenue Service. About Form SS-4, Application for Employer Identification Number
- Proof the business legally exists. Articles of Incorporation for a corporation, or a Certificate of Organization for an LLC, filed with your state’s Secretary of State. If the originals are gone, order copies or a Certificate of Good Standing from the same office for a small fee.
- Financial statements and tax returns. Recent business returns, bank statements, and profit-and-loss statements. Annual revenue and time in operation drive the risk assessment. The business name on your application must match your state filings exactly.
- Corporate resolution. A written authorization from the board or LLC members naming the person who may sign on behalf of the company. This shows the lessor that whoever signs can actually bind the business.
Business Credit and the Personal Guarantee
Lessors evaluate your company through commercial credit bureaus such as Dun & Bradstreet and Equifax. The Dun & Bradstreet PAYDEX score runs from 1 to 100, and higher scores signal that the business pays promptly. Those files are built from the company’s own payment history, separate from the owner’s personal credit.
If the business is new or its credit file is thin, expect a personal guarantee to be required. You sign as an individual, agreeing to cover the lease if the business can’t. That means providing your Social Security number, consenting to a hard credit inquiry, and letting your personal FICO score weigh heavily in the decision.
A guarantee is not a formality. If the business defaults, the lessor can pursue your personal assets, including bank accounts, investments, and in some cases your home, to recover what’s owed. The obligation runs until the lease matures and all fees clear, even if you sell the business or leave its management. The only clean exit is a written release from the lessor, which is rarely offered.
If your company has no credit profile yet, plan to spend six months to a year building one before you apply. Register for a free D-U-N-S Number, run all company transactions through a dedicated business bank account, and set up trade accounts with vendors who report net-30 or net-60 payments to the business bureaus. PAYDEX rewards early payment, so paying before the due date builds the score faster than paying on time.3Dun & Bradstreet. How to Establish and Seek to Build Business Credit
Steps From Application to Keys
You submit the application through a dealership’s fleet or commercial department, or through a standalone commercial leasing company. Fleet desks are built for business clients and underwrite against the entity’s financials rather than running a consumer deal. The underwriter reviews your EIN, financials, and credit data, then issues an approval or a counter-offer with terms such as a larger security deposit or a shorter term.
At closing, an authorized officer signs using the title listed on the corporate resolution: President, Managing Member, or equivalent. The signature binds the company to every term in the contract, including the mileage cap, maintenance duties, and end-of-lease obligations. You pay initial costs at signing, typically the first month’s payment plus an acquisition fee (sometimes called a bank fee) that generally runs between $595 and $1,095 depending on the lessor and the vehicle.
Before you can take delivery, you have to show proof of commercial auto insurance. Business auto policies commonly use a Combined Single Limit rather than the split limits on a personal policy. Lessors usually require a CSL of at least $500,000, and many set the floor at $1,000,000 for higher-value vehicles. The lessor also has to be listed as a loss payee or additional insured. After signing, the title and registration are processed in the business name, and the company handles renewals and any local vehicle property taxes going forward.
Choose the Lease Structure Before You Sign
Business leases come in more shapes than personal leases, and the structure decides who carries the depreciation risk.
Closed-End
You return the vehicle at the end of the term and owe nothing beyond excess mileage or wear-and-tear charges. The lessor absorbs any shortfall in resale value.4Federal Reserve Board. Vehicle Leasing – End of Lease Costs Closed-End Leases Costs are predictable, which is why many businesses choose this format.
Open-End
You’re responsible for the gap between the contract’s estimated residual value and the vehicle’s actual market value at turn-in. If the car is worth less, you pay the difference; if it’s worth more, you may receive a refund. Monthly payments can be lower because the lessor isn’t pricing in residual risk, but you carry that risk instead.
TRAC
A Terminal Rental Adjustment Clause lease is a specialized open-end structure common on commercial trucks and fleet vehicles. You and the lessor agree on a residual at signing. Set it higher for lower payments, or lower for higher payments, depending on cash-flow preferences. At the end, you either buy the vehicle at the agreed price or cover any shortfall.5Comptroller of the Currency. Lease Financing
Tax Deductions on a Business Lease
The IRS lets you deduct the business-use portion of the lease, but you have to pick one of two methods and stay with it for the entire lease term, including any renewals.6Internal Revenue Service. Income and Expenses 5
- Actual expense method. Deduct the business-use percentage of every vehicle cost: lease payments, fuel, insurance, maintenance, and repairs. If the car is used 70 percent for business, you deduct 70 percent of those costs.7Internal Revenue Service. Topic No. 510, Business Use of Car
- Standard mileage rate. The IRS rate for 2026 is 72.5 cents per business mile. If you use this method on a leased vehicle, you must use it for the whole lease.8Internal Revenue Service. IRS Sets 2026 Business Standard Mileage Rate at 72.5 Cents Per Mile
You can’t combine the two; deducting lease payments and the mileage rate together is not allowed.6Internal Revenue Service. Income and Expenses 5
If the vehicle’s fair market value at the start of the lease exceeds a set threshold, the IRS also requires you to add a “lease inclusion amount” to gross income each year, which partially offsets the deduction. For leases beginning in 2025, the threshold is $62,000, and the inclusion amount grows with the vehicle’s value and each year of the lease.9Internal Revenue Service. Revenue Procedure 2025-16 The IRS publishes updated tables each year; check the current revenue procedure if your lease starts in 2026 or later.
Whichever method you pick, keep a contemporaneous log with the date, destination, business purpose, and miles for each trip.7Internal Revenue Service. Topic No. 510, Business Use of Car Mixed use means tracking both business and personal miles so you can compute the percentage. Weak records can wipe out the deduction under audit.
Mileage, Early Termination, and End-of-Lease Costs
Most leases cap annual mileage at 12,000 or 15,000 miles. Overage charges usually run 10 to 25 cents per mile, and pricier vehicles carry higher per-mile fees because excess miles hit their resale value harder. If you expect heavy use, negotiate a larger mileage allowance at signing. It almost always costs less than paying the penalty at turn-in.10Federal Reserve Board. Vehicle Leasing – More Information About Excess Mileage Charges
Ending a business lease early triggers a termination charge. The common formula is the remaining lease balance minus the vehicle’s current wholesale value, plus a possible disposition fee and taxes. Several methods exist for allocating payments between depreciation and the rent charge over the term; the Constant Yield (Actuarial) method is the most widely used.4Federal Reserve Board. Vehicle Leasing – End of Lease Costs Closed-End Leases Because the standardized consumer disclosures don’t apply, ask the lessor to walk you through the exact termination formula before you sign.
At the natural end of the term, you generally have three options: return the vehicle and pay excess mileage, wear-and-tear, and a disposition fee (commonly $300 to $400); buy the vehicle at the residual value stated in the contract; or negotiate a short-term or month-to-month extension. On an open-end lease, returning the vehicle also means settling any gap between the estimated residual and actual market value. Start reviewing your options several months before the lease expires so you can negotiate or line up a replacement without time pressure.
