President Donald Trump said early Monday there’d be “no change” to 401(k) plans, as his administration and Congress push to enact a tax-reform package this year.

In a tweet, Trump said “This has always been a great and popular middle class tax break that works, and it stays!”

Trump’s tweet follows a report last week in The Wall Street Journal that there are proposals about capping the amount that Americans may contribute before taxes to 401(k) plans — to as little as $2,400 per year — and individual retirement accounts, as Republicans look for ways to generate revenue to support cutting individual taxes.

Trump’s promise comes as lawmakers are continuing to write tax-policy legislation, and have only publicly released a framework. Many of the details — including on retirement plans — remain to be filled in. The framework says tax reform will aim to “maintain or raise retirement plan participation of workers and the resources available for retirement.”

There is no publicly available bill text as yet. Over the weekend, Senate Majority Leader Mitch McConnell told Fox News that he didn’t want to go into details of the tax-reform plan, and said it would be “hashed out in the open” by congressional committees.

Trump’s tweet may not be the final word on 401(k) plans and tax reform. On another hot-button issue, health care, Trump has lately given mixed signals and stirred confusion about his position. Last week, he commended work by Sens. Lamar Alexander and Patty Murray on a deal to stabilize Obamacare insurance markets. But later on Twitter, he didn’t offer support for the senators’ bill.

The New York Times also reported that proposals under discussion could cap the annual amount workers can set aside to as low as $2,400 for 401(k) accounts.
