any people make donations at the end of the year. To be deductible on your 2017 return, a charitable donation must be made by December 31, 2017. According to the IRS, a donation generally is “made” at the time of its “unconditional delivery.” But what does this mean?

Is it the date you write a check or charge an online gift to your credit card? Or is it the date the charity actually receives the funds? In practice, the delivery date depends in part on what you donate and how you donate it. Here are a few common examples:

Checks. The date you mail it.

Credit cards. The date you make the charge.

Pay-by-phone accounts. The date the financial institution pays the amount.

Stock certificates. The date you mail the properly endorsed stock certificate to the charity.

To be deductible, a donation must be made to a “qualified charity” — one that’s eligible to receive tax-deductible contributions. The IRS’s 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. You can access it at https://www.irs.gov/charities-non-profits/exempt-organizations-select-check. Information about organizations eligible to receive deductible contributions is updated monthly.
