Deducting lease payments

Monthly lease payments on a vehicle used in your business are deductible to the extent of business use. If you use the vehicle 70% for business, deduct 70% of each lease payment. The standard mileage rate is also available for leased vehicles, but if you start with the standard rate you must continue using it for the entire lease period — switching mid-lease is not allowed.

Lease inclusion amount

For luxury leased vehicles (those with a fair market value above an annual IRS threshold), the IRS publishes a "lease inclusion" table that adds a small amount to your taxable income each year. The mechanic mirrors the luxury-auto depreciation cap that applies to purchased vehicles — without it, lessees would have an unlimited deduction while purchasers were capped.

How to find the inclusion amount

IRS Rev. Proc. tables (issued each spring for the prior year) list inclusion amounts by vehicle FMV and lease year. The inclusion is small — generally under $100 in early lease years for a $60,000-$80,000 vehicle. Most filers ignore it as immaterial; for high-FMV vehicles it can reach a few hundred dollars per year.

Down payments and acquisition fees

A down payment or capitalized cost reduction at lease inception is amortized over the lease term, not deducted in full at signing. Lease acquisition fees are similarly amortized. Annual registration, insurance, and gas are deductible separately by business-use percentage if you use the actual-expense method — or absorbed in the standard rate.

Buying out at lease end

If you exercise the lease-end purchase option, the lease ends and a new depreciable asset begins. The cost of the buyout becomes the basis for depreciation going forward. Track this transition carefully — it changes the deduction methodology mid-year.

Documentation that survives an exam

An IRS examination of this deduction will request three things: proof of payment (bank or card statement), proof of the underlying transaction (invoice or receipt), and proof of business purpose (a contemporaneous note or calendar entry). The first two are usually trivial to produce; the third is where most filers fall short. Capturing business purpose at the moment of the expense — a one-line note in your bookkeeping software or a category and memo on the receipt-capture app — converts a generic charge into a documented deduction that will withstand scrutiny three to six years later when memory has faded.
