donating used car

Keep a thorough paper trail. If your donation is worth more than $500, you’ll have to attach IRS Form 8283 to your tax return.
If it’s worth more than $5,000, your documentation must include an outside appraisal.
You’ll also need proof of the donation used car, such as a receipt from the charity and a copy of the title change.

Be detail-oriented. This paper trail may seem cumbersome, but think about it: This may be one of the biggest charitable donations you ever make. 
By taking the time to dot the i’s, you can make sure that the charity gets the most benefit and you get the biggest possible deduction.
