Can I File a Tax Extension Online?

Yes — you can file for a free 6-month extension electronically in minutes. Use IRS Free File or any major tax software to e-file Form 4868 before the April 15 deadline — no explanation required. You can also file the extension through IRS Direct Pay while making a payment, or mail a paper Form 4868. The extension gives you until October 15 to file your return. Remember: it extends the time to file, not to pay — you still need to estimate and pay your tax by April 15 to avoid the failure-to-pay penalty. Most states accept the federal extension automatically, but check your state's rules.
