Here is an answer to your question.l I have no idea if this website is legitimate but I read the same thing on several websites. I would suggest you try to donate the $300/$600 for a couple donation deduction limit for this year which personal taxes are allowing. However, the way things are going perhaps the govt will allow the $300/$600 again next year.
