Kelley Blue Book (KBB)
A popular vehicle valuation reference — but NOT your tax deduction.
What it means
Kelley Blue Book provides estimated retail and trade-in values for used vehicles. Donors often assume KBB equals their deduction, but the IRS requires the actual auction sale price (which is usually lower than KBB retail). Use KBB only as a rough estimate; rely on Form 1098-C for the actual deduction.
