If you are not ready to file your tax return by the deadline, you may request a tax extension before the due date. In this case, the revised due date to file your tax return will be on October 17, 2022. Please note that your tax bill will be due on April 18 itself. If you get a tax extension, you will only get more time to file your return. This does not mean you will get more time to pay your taxes. If you are not able to pay your tax before the due date, you can also apply for the IRS installment plans. Such a plan would let you pay over time. You can apply for it on the IRS website.
