· Contribute to Qualified Charities. If you plan to take an itemized charitable deduction on your 2012 tax return, your donation must go to a qualified charity by Dec. 31. Ask the charity about its tax-exempt status. You can also visit IRS.gov and use the Exempt Organizations Select Check tool to check if your favorite charity is a qualified charity. Donations charged to a credit card by Dec. 31 are deductible for 2012, even if you pay the bill in 2013. A gift by check also counts for 2012 as long as you mail it in December. Gifts given to individuals, whether to friends, family or strangers, are not deductible.
