Donations to qualified charities are generally fully deductible, and they may be the easiest deductible expense to time to your tax advantage. After all, you control exactly when and how much you give. But before you donate, it’s critical to make sure the charity you’re considering is indeed a qualified charity — that it’s eligible to receive tax-deductible contributions.

The IRS’s recently launched online search tool, Exempt Organizations (EO) Select Check, can help you more easily find out whether an organization is eligible to receive tax-deductible charitable contributions. The previous source for this information was IRS Publication 78, which is incorporated in the new tool.

You can access EO Select Check athttp://apps.irs.gov/app/eos. Information about organizations eligible to receive deductible contributions is updated monthly.

Finally, in an election year, it’s important to remember that political donations aren’t tax-deductible.
