The U.S. Internal Revenue Service on Wednesday released final rules for a new tax on medical devices, products ranging from surgical sutures to knee replacement implants, that starts next year as part of President Barack Obama's 2010 healthcare law.
The 2.3-percent tax must be paid, effective after December 31, by device-makers on their gross sales. The tax is expected to raise $29 billion in government revenues through 2022.
Companies including Boston Scientific Corp, 3M Co and Kimberly-Clark Corp have been lobbying the U.S. Congress for a repeal of the tax.
A repeal bill passed the Republican-controlled U.S. House of Representatives in June, but it has not been voted on by the Democratic-controlled Senate.
Many medical devices that are sold over-the-counter - such eyeglasses, contact lenses and hearing aids - are exempt from the tax, as are prosthetics, the IRS said.
