Filing taxes late is generally quite bad if you owe money, as it triggers a severe "failure-to-file" penalty of 5% of the unpaid tax amount per month, capping at 25%. If you are due a refund, there is no penalty for filing late, though you should file to claim your money.

What happens if you file a tax return late?

You might have to pay IRS penalties and interest if you file your federal income tax return after the April deadline, your due date isn't extended, and you end up with a tax bill.

The October deadline is for filing, not paying; if you owe, payment was due in April, so you'll likely face both penalties and interest until you file and pay, but you won't be penalized if you're due a refund.
