Did you buy a motor vehicle in 2014 in Nevada?
The IRS defines a motor vehicle as a car, motorcycle, motor home, SUV, truck, van, or off-road vehicle.
If you do not take the IRS standard deduction, you can add the Nevada state sales tax, as an itemized expense.
The 2014 Form 1040 Schedule A instructions explain that only the Nevada state sales tax rate of 6.85% of the purchase price is allowed.
I have the knowledge, skill, and ability to complete the IRS' State and Local General Sales Tax Deduction Worksheet-- Line 5B.
