If you made a donation to the Haiti relief and you would like to claim it on your tax return you must do so by the end of the month, that's according to the Internal Revenue Service.
Individuals and corporations have until midnight on Sunday, February 28, to make cash contributions to charities providing earthquake relief in Haiti. These contributions can be claimed on either a 2009 or 2010 return, but not both.Contributions made after that date but before the end of the year can only be claimed on a 2010 return. Contributions made by text message, check, credit card or debit card qualify for this special option. Donations charged to a credit card before the end of February count for 2009. This is true even if the credit card bill isn't paid until after Feb. 28. Also, checks count for 2009 as long as they are mailed by the end of this month and clear your financial institution shortly thereafter.
The special provision was enacted January 22, and does not apply to contributions of property. Eligible contributions must be made specifically for the relief of victims in areas affected by the Jan. 12 earthquake in Haiti.
Gifts made directly to individual victims are not deductible. You can find a one page notice describing the provision on IRS.gov.
