FACT: Pay-Go is a congressional rule that requires tax cuts or spending increases be offset – aka paid for. If a bill increases the deficit, automatic cuts are made UNLESS the House and the Senate vote to waive the requirements.
FACT: Senate Majority Leader Mitch McConnell and House Speaker Paul Ryan, have said they will waive those requirements for the tax cuts, meaning there would not be across the board mandatory spending cuts.
FACT: In fact, the only way Medicare would be cut because of the tax cuts is if Democrats like Sherrod Brown demanded it. The waiver would require 60 votes to pass in the Senate, meaning Democrat votes will be needed.
NBC NEWS: “It is unlikely Medicare spending will actually be reduced next year as an immediate consequence of the tax bill — in fact, doing so could require Democrats to insist on cuts over Republican objections.”
Senator McConnell And Speaker Ryan Have Said They Would Waive Pay-Go. “Critics of tax reform are claiming the legislation would lead to massive, across-the-board spending cuts in vital programs—including a four percent reduction in Medicare—due to the Pay-Go law enacted in 2010. This will not happen.” (“Joint Statement from Leader McConnell and Speaker Ryan on Misleading Democrat Claims about Tax Reform,” Senate Majority Leader Website, 12/01/17)
“There Is No Indication” Republican Leadership Would Demand Automatic Cuts To Pay For Tax Cuts. “There’s no indication at all that House or Senate leaders plan on pursuing automatic cuts via their tax bill.
