Yearly I pay for my car tag fee and tax (AD valorem tax). Is this amount deductible?

[matazap]

I have this Alabama Department of Revenue - Motor Vehicle Registration Tag and Tax Receipt. May I use that?

Second question: 401K is taken from my paycheck. May I use that amount also to deduct my tax to be paid? How can I get the info over total amount paid the whole last year?
thanks.

You can deduct your ad valorem tax. You cannot deduct registration fees and tag fees that are not based on the value of the vehicle and assessed on an annual basis. 

As for the 401(k) deduction amounts, that has already been deducted from your taxable income.  It is not included in Box 1 of your W-2.  So no - you cannot deduct the amount of your 401(k) contributions again.
