The letter marks the latest in a yearslong effort by Democrats to get access to Trump's financial documents.
The letter signals that Neal could be preparing to issue a subpoena or take other legal action, including a lawsuit, to compel officials to obtain and turn over the president's returns.
"Remember, I got elected last time - the same exact issue", Trump said. Neal had requested six years of Trump's personal and business tax returns. Mnuchin is the Cabinet secretary that oversees the IRS.
But the IRS has said that he could release the returns even if they are under audit.
The fight over access to Trump's tax returns is expected to be a long legal battle.
But in the letter, Mr Neal told IRS Commissioner Charles Rettig: "None of the concerns raised can legitimately be used to deny the committee's request".
He said Treasury respects lawmakers' oversight duties and would make sure taxpayer protections would be "scrupulously observed, consistent with my statutory responsibilities" as the department reviews the request. "Frankly, the people don't care".
At congressional hearings, Mnuchin accused lawmakers of seeking Trump's returns for political reasons.
Neal's initial letter, sent a week ago, didn't lay out any consequences for the IRS if it didn't comply, and a spokesman said a likely course would be a second, more insistent, letter.
"We intend to follow through with this", Neal said.
Trump declined to provide his tax information as a candidate in 2016 and as president, something party nominees have traditionally done in the name of the transparency.
On Saturday the Washington Postreported that the House ways and means chairman, Richard Neal of MA, wrote to the Internal Revenue Service commissioner, Charles Rettig, saying Neal wrote that a failure to comply with the new deadline would be "interpreted as a denial of my request".
Donald Trump will have to release five years of tax returns if he wants appear on the IL 2020 presidential ballot, the state's senate has ruled.
