"As far as my taxes are concerned, the only one that cares is the press, I will tell you. And even the press, I'll tell you, it's not a big deal," Trump said in an interview with ABC News on Monday. "I think people don't care."
But a majority of voters think it's either very important or somewhat important for candidates to release their returns, according to a new Monmouth University poll published last week.
Seated beside Trump during the interview, Republican vice presidential candidate Mike Pence said he will release his own tax returns this week.
"I'm releasing my tax returns, Donald Trump will release his tax returns," Pence said. "I'll give mine to y'all this week, and he's going to provide his after a routine audit is done."
Trump has repeatedly said he will release his tax returns after the IRS completes a "routine audit," but his campaign has also said that might not be before the November election. Democratic nominee Hillary Clinton and her running mate, Tim Kaine, both released their tax returns in early August.
“When the audit is done, I’ll release them," Trump said in Monday's interview. "I don't know when that's gonna be, it could be soon, it could be not."
