Key 2026 Deadlines
The standard April 15 filing deadline remains the same, but weekends and holidays can shift the date slightly. Mark your calendar now so you don’t miss important due dates.
When to File an Extension
If you need more time, file IRS Form 4868 by the deadline to get an automatic six-month extension. Remember that this extends only your filing deadline, not your payment deadline.
Avoiding Extension Penalties
You should estimate and pay any amount owed by the original filing deadline. Late payments can incur penalties and interest, even if you file for an extension.
Business and Self-Employed Deadlines
Self-employed taxpayers often have additional deadlines for quarterly estimated taxes. Planning ahead helps avoid a surprise balance due when you file your annual return.
What Happens After You File
After filing, track your return status and refund through the IRS website. If you owe, pay as soon as possible to minimize penalties and interest.
