Business Car Lease Tax Benefits: Write-Offs, Section 179, and the Catch

By Sarah Mitchell2026-04-087 min read

A business lease often lets you deduct the entire payment as an operating expense — simpler than depreciation. But luxury leases face an "inclusion amount," and you must allocate personal vs business miles.

Key takeaways

  • Business leases are often deductible as an operating expense, payment and all.
  • Luxury leases may require adding back an "inclusion amount" to income.
  • Personal vs business mileage must be tracked to support the deduction.
  • Section 179 usually favors purchase; leasing favors deducting the payment.

The simple version: deduct the payment

For a vehicle used in business, a lease payment is generally a deductible operating expense — you write off the business-use portion of the payment each month, rather than depreciating a purchase. That is simpler than tracking depreciation schedules and can be gentler on cash flow early on.

The luxury-lease inclusion amount

High-priced leases come with a catch: the IRS requires you to add back a portion of the lease value to income via the "inclusion amount" table. It offsets part of the deduction on expensive vehicles. The threshold and table update yearly, so pull the current figure rather than guessing. This is the main reason a cheap business lease deducts cleaner than a six-figure one.

Mileage logging is non-negotiable

Watch out

Only the business-use percentage of the payment is deductible. If you use the car 70% for work, deduct 70% of the lease. The IRS expects a mileage log; "mostly business" is not a record. Track it from day one.

Open-end leases and businesses

Many business leases are open-end, shifting resale risk to you in exchange for a lower payment — see <a href="/guides/open-end-closed-end-car-lease-differences">open vs closed end</a>. That risk is separate from the tax treatment, so weigh both. For the ownership-side deduction, our <a href="/calculators/section-179/">Section 179 tool</a> models the purchase path.

Frequently asked questions

Can I deduct my business car lease payment?+
Yes — the business-use portion of the lease payment is generally deductible as an operating expense. Only the work-use percentage counts, so track mileage.
What is the lease inclusion amount?+
For expensive leases, the IRS makes you add back part of the lease value to income, limiting the deduction. It applies above a price threshold that updates yearly; check the current table.
Is leasing or buying better for a business?+
Leasing gives a steady payment deduction with little cash out; buying can use Section 179 for a large first-year write-off. The better choice depends on cash flow and the vehicle price.
Do I need a mileage log for a leased business car?+
Yes. The deduction is based on business-use percentage, and the IRS expects documentation. A simple dated log of business trips supports the claim if questioned.
