Do you have to file on April 15 even if you are getting a refund?

Yes, you generally need to file your tax return by April 15, even if you expect to receive a refund. Failing to file on time can delay your refund and may result in penalties or interest if you owe taxes. However, if you need more time, you can file for an extension, which typically allows you until October 15 to submit your return, though any taxes owed must still be paid by the original due date.
