Tax Tips: Deducting Income taxes or sales taxes
Included in your deduction for state income taxes paid will be whatever amounts were withheld on your paychecks and reported on your W-2, any state taxes paid during 2007 for a prior year amount owed, any state tax estimates paid during 2007, any state tax refund from a prior year that you elected to have applied to 2007 taxes. You should not deduct any penalties or interest paid related to your state income taxes. Those are not deductible.
In order to deduct sales tax paid, you should keep receipts to substantiate the amount you are claiming. In the event that you do not have receipts to substantiate the actual amount of sales tax paid, you can use the amounts allowed by the IRS on their sales tax tables.
