These items are only deductible if you itemize. One of the common issues with charitable deductions is people donating to places like Goodwill, but not documenting what was given and the fair market value of the donated items.
Another common item overlooked is volunteer mileage. Make sure you document all of your monetary and goods donations so you can maximize your deduction.
Beginning in tax year 2008, you can add up to $500 ($1,000 married joint) in property tax to your standard deduction even if you don’t itemize deductions. I noticed that a lot of people missed this deduction on their 2008 tax returns.
