If you are required to file your taxes, you should still file, even if you cannot pay, as the failure-to-file penalty may be 10 times more than the failure-to-pay penalty.
If you are unable to pay in full, try to file your tax return by the deadline of April 18th, 2023 and pay as much as you can.
In addition, April 18th is also the due date for Tax Year 2023 first quarter estimated tax payments for those making estimated payments.
