Final answer:
The inclusion amount for a leased automobile is indeed adjusted by the business usage percentage, reflecting accurate tax deductions based on the vehicle's use for business purposes.
Step-by-step explanation:
The statement that the inclusion amount for a leased automobile is adjusted by a business usage percentage is True. When a business leases a vehicle, the IRS requires that the deductible expenses reflect the percentage of time the vehicle is used for business purposes. If the leased vehicle is also used for personal purposes, not all lease payments can be deducted from the business's taxable income. Instead, the inclusion amount, which is a portion of the lease payment that is added to the taxpayer's income, must be adjusted by the percentage of the vehicle's use that is attributable to the business. This is done to prevent taxpayers from deducting personal expenses as business expenses on their tax returns.
