Tax Year 2025
Your actual return
Filing Form 4868 by the original deadline (2026-04-15) automatically pushes your filing deadline back six months, to mid-October, with no reason required and no cost. It does NOT extend the time to pay: any balance you owe is still due on the original date, and interest plus a late-payment penalty (smaller than the late-filing penalty) starts accruing the day after if you don't pay it.
AsasifyTax's own extension filing today covers business returns (Form 7004) and nonprofit returns (Form 8868). An individual Form 4868 filing flow isn't built yet - if you need to extend your own personal return, file directly with the IRS at irs.gov using their Free File or Direct Pay options.
