Senators from New York and Florida on Thursday proposed a bill that encourage chairtabile donations to the Haitian earthquake relief effort by making them more tax-friendly.

The bill would lift limits on tax write-offs to donations that are larger than 50 percent of their annual income. Under current laws, corporations cannot write off donations more than 10 percent of their revenues.

Sens. Charles Schumer (D-N.Y.), Kirsten Gillibrand (D-N.Y.), Bill Nelson (D-Fla.) and George LeMieux (R-Fla.) proposed the bill.

“Haiti needs our help now more than ever before and we need to make sure U.S. citizens have every opportunity to provide the Haitian people the humanitarian aid they need,” said Schumer in a statement.

New York City and South Florida have the two largest Haitian immigrant populations in the U.S.

Lawmakers ratified similar changes after Hurricane Katrina hit the Gulf Coast in 2005.
