Today is the due date for your tax return. If you anticipate you will owe taxes, if you do not file today, you will incur a penalty for not filing timely and also interest and penalties on the taxes you owed by the due date today.
If you think you will have a refund, there is no penalty to filing past today. You can file the return at any time and get the refund without penalty or interest being charged to you.
Good luck!
