The deadline to file your 2018 tax return was April 15, 2019.
What if I missed the deadline?
Though the April deadline has passed, you may still be able to file your tax return. If you are due a refund, the IRS says that there is no penalty if you file a late tax return. However, if you owe tax, and you failed to file and pay on time, the IRS states that you “will most likely owe interest and penalties on the tax you pay late.”
Tax returns that are due a refund for withholding or estimated taxes must be filed within 3 years of the return due date to claim your refund. If you cannot pay what you owe, you can request an additional 60-120 days to pay your account in full through the Online Payment Agreement application or by calling 1(800) 829-1040.

Late filing when you are receiving a tax refund
The IRS penalty for late filing without an extension is a percentage of taxes you owe. This means that if you’re receiving a federal tax refund, there’s no penalty for filing a late tax return. Late filing penalties may vary for state returns depending on your state, even with a tax refund, so check with the state. Regardless, it’s recommended to file as soon as possible.
Late filing penalty
You will have to pay a late filing penalty if you have not filed your federal tax return by the IRS filing deadline, and you don’t have proof of reasonable cause.
You may be subjected to a penalty of 5% of the federal amount due on your return for each month or partial month it’s considered past-due. The penalty is limited to 25% of the tax you owe.
Late payment penalty
A late payment penalty can occur for federal taxes not paid by the due date.
The maximum federal payment penalty is 25% of the amount you owe.
Proof of reasonable cause
Federally imposed late payment penalties may be waived if you can show reasonable cause for not filing or paying on time.
