People who give to charities providing earthquake relief in Haiti can claim these donations on the tax return they are completing this season, according to the Internal Revenue Service. Taxpayers who itemize deductions on their 2009 return qualify for this special tax relief provision, enacted Jan. 22. Only cash contributions made to these charities after Jan. 11, 2010, and before March 1, 2010, are eligible. This includes contributions made by text message, check, credit card or debit card. The new law only applies to cash (as opposed to property) contributions. The contributions must be made specifically for the relief of victims in areas affected by the Jan. 12 earthquake in Haiti. Taxpayers have the option of deducting these contributions on either their 2009 or 2010 returns, but not both.
