US federal individual income tax; state deadlines and extension rules require separate verification.
An ordinary federal filing extension generally gives more time to send your individual income-tax return, not more time to pay the tax. Treat filing and payment as two separate tasks.
First, check the deadline for your tax year and circumstances on IRS.gov. Disaster relief, living abroad and other special situations can change the usual rules. Do not apply a date from an old article to your case or assume a federal extension automatically handles your state return.
If you need an extension, use an IRS-listed method by the applicable deadline and keep proof. Estimate what you owe using complete records, subtract payments already made and pay what you can by the payment deadline.
If you cannot pay in full, do not ignore the filing requirement. Review IRS payment-plan options directly, including eligibility, fees and ongoing interest or penalties. A plan is not tax forgiveness, and no private company can guarantee that your balance will disappear.
After applying or paying, retain confirmations, verify the correct tax year and keep notices together. If a deadline has already passed, consult current IRS guidance or a qualified preparer promptly rather than waiting for the next filing season.
