“First, you may face a failure-to-file penalty. This is equal to 5% of the taxes you haven’t paid less any available credits, charged monthly for up to 5 months,” read Fidelity’s website. “If you’re more than 60 days late, the minimum penalty is the smaller of 100% of the taxes you owe or $485.”
“You could also get hit with a failure-to-pay penalty. This one is assessed at the smaller rate of 0.5% of your unpaid taxes, but it’s reapplied each month until you max out at 25% of your unpaid balance,” continued Fidelity. “If you owe both penalties in a given month, the failure-to-file penalty is reduced so that you are not paying more than 5% in penalties each month.”
The IRS has laid out a process for requesting a tax filing extension through various methods. Any of these will push your tax filing deadline to Thursday, October 15.
