New First-Time Donor's Super Credit (FDSC) means charitable donation can garner tax savings "between 61.1% and 74.4%" for some Canadians.
"Imagine making a $1,000 donation to charity with an after-tax cost of only $256. It turns out you might not have to imagine it; it’s a reality for some Canadians, thanks to the new First-Time Donor’s Super Credit (FDSC) that was announced in the 2013 federal budget. The FDSC seems to be a well-kept secret. This specific measure in the budget received royal assent in late June, and is retroactive to donations made on or after March 21, 2013. It’s only a temporary program, for now, and is set to expire at the end of 2017. " -- Preet Banerjee, the Globe and Mail
