An extension gives you more time to file, not to pay. Estimate and pay what you owe by Tax Day to avoid penalties and interest. Clients get extensions filed free.
Paid on a 1099? You have quarterly estimated payments too: see our independent contractor tax checklist. Ready to file? Gather everything with the document checklist, then get started.
Dates follow the IRS calendar; disaster-area relief can extend them for affected counties.
