Rep. Thomas Massie reintroduced legislation on Thursday that would nix an additional tax on retirement benefits.

The Kentucky Republican’s Senior Citizens Tax Elimination Act, which he has introduced every session of Congress since 2012, would amend the tax code to eliminate the tax on gross income of Social Security benefits.

He said in a statement that Social Security is already taxed through the payroll tax, yet seniors are still “required to list these benefits as taxable income on their tax returns.”

“This is simply a way for Congress to obtain more revenue for the federal government at the expense of seniors who have already paid into Social Security,” he said in a statement. “My bill would exempt Social Security retirement benefits from taxation and boost the retirement income of millions of older Americans.”

Some version of the bill has been floating around Washington since 2003, when then-Rep. Ron Paul, Texas Republican, introduced it.

Now, the measure may gain traction after President Trump made clear on the campaign trail that he intended to end taxes on Social Security benefits.

Congressional Republicans are currently working out a budget blueprint in both chambers to begin work on passing much of Mr. Trump’s agenda, and at the center of it all is his wish to extend his 2017 tax cuts.

House Speaker Mike Johnson, Louisiana Republican, and many other House Republicans met for hours with the president on Thursday to iron out the details on their tax plan. Among the priorities Mr. Trump presented to the lawmakers was to halt taxes on Social Security, White House Press Secretary Karoline Leavitt told reporters.

Other priorities included no tax on tips and overtime, adjusting the State and Local Tax cap, eliminating special tax breaks for billionaire sports team owners, closing the carried-interest tax deduction loophole, and tax cuts for Made-in-America products.

“This will be the largest tax cut in history for middle-class working Americans. The president is committed to working with Congress to get this done,” Ms. Leavitt said.
