The U.S. Senate is set to repeal a tax provision of the new health care law, rescinding a burdensome tax requirement that's unpopular with businesses.

The U.S. House of Representatives has already passed the measure. Starting in 2012, the provision would require millions of businesses to file tax forms for every vendor selling them more than $600 in goods each year.

Congressional Democrats and the White House also support the repeal. They say the bill is part of inevitable tinkering that will be needed to improve the health measure.

Republicans hope Tuesday's vote is the first of many aimed at rolling back what they call 'Obamacare.'

"I hope this is the first of many successful health-spending-law repeal votes and that we can replace the law with the types of common-sense reforms that lower costs and encourage job creation," Senate Minority Leader Mitch Mcconnell, R-Ky., said.

Democrats passed the health care law last year with no Republican support, when they had majorities in both the House and Senate.
