President Trump said Thursday that he is working on a new tax cut for middle-class households, to be unveiled “sometime in the next year.”

Speaking to lawmakers at the GOP retreat in Baltimore, Trump said, “we’re working on a tax cut for the middle-income people that is going to be very, very inspirational. … it'll be a very, very substantial tax cut for middle-income folks who work so hard.”

The president, who has hinted at tax cuts several times over the last year without producing any specific proposals, provided no further details. Although House Speaker Nancy Pelosi and other Democratic lawmakers have said they are open to the idea of a middle-class tax cut, their insistence that new cuts be paid for with tax increases on the wealthy make it unlikely that the president will be able to make a deal on the issue with a divided Congress.

White House economic adviser Larry Kudlow told reporters Friday that the tax-cut plan would be made public “sometime in the middle of next year,” putting the release date close to the 2020 election.

Republican lawmakers may be more focused on making permanent their 2017 tax cuts, some of which are set to expire after 2025. “The first and most important step is we can make the cuts for families and small business permanent,” Rep. Kevin Brady, the ranking Republican on the tax-writing House Ways and Means Committee, said Friday.
