It’s Tax Day.
Even if you’ve waited until the last day to file your taxes, you’re not alone — millions of people will file their tax returns today, including billionaire businessman and 13-year “Shark Tank” staple, Mark Cuban.
Cuban took to X, formerly Twitter, on Sunday to answer a question posed by a user who asked if Cuban pays more than the required amount of taxes.
“I pay what I owe,” Cuban posted, adding that on Monday, he would wire transfer $288 million to the IRS.

Cuban also wrote that it was “unreal” to handle that amount of money.
“Never in my wildest dreams did I think I would be here,” he stated.

Like Cuban, a spate of Americans will file their taxes on Monday. IRS Commissioner Danny Werfel told CNN Business that the IRS received more than 100 million returns as of Friday and expects to receive “tens of millions more returns” by the deadline.
“We’re seeing a flurry of tax returns coming in during the final hours,” Werfel stated.
Taxes are due by 11:59 p.m. today in individual-specific time zones, with a few exceptions.
The IRS revealed on Monday that Americans who filed from January through early April received more than $200 billion in refunds, with the average refund being $3,011 — up from the $2,878 average last year.
How to File a Tax Return on Deadline Day
For those scrambling to file their taxes Monday, the IRS has free resources available, including Direct File, a program piloting in 12 U.S. states this year that allows taxpayers to file directly with the IRS. New York, California, Florida, Texas, and Washington are all states covered by Direct File this year.
Those with incomes of $79,000 or less can file taxes for free through a trusted IRS Free File partner, including TaxAct, FileYourTaxes, and FreeTaxUSA.
Anyone who needs more time to file has the option of requesting an extension by today that pushes the deadline six months ahead to October 15. The extension only applies to the filing, not to the balance — so even with an extension, taxpayers still have to pay what they owe by the April 15 deadline or face added late fees and penalties.
The IRS predicted that about 19 million Americans will file for an extension this year.
