WASHINGTON — The House passed a package of tax breaks Thursday designed to boost charitable donations by seniors, private foundations and procrastinators.

One provision provides tax breaks to people over 70 who make donations from their individual retirement accounts. Another reduces excise taxes on private charitable foundations.

Procrastinators would be able to claim tax deductions for donations made after the end of the year, as long as they were made by April 15. Other provisions provide tax breaks for landowners who donate land for conservation purposes, and businesses that donate food to food banks.

The White House threatened to veto the bill because it would add $16 billion to the budget deficit over the next decade. In a statement, the White House criticized House Republicans for supporting tax breaks that mainly benefit wealthier Americans while refusing to help low-income families by extending unemployment benefits for the long-term unemployed.

The vote was 277-130 to pass the bill. Fifty-six Democrats joined 221 Republicans to vote in favor of the bill.
