If you will be receiving a tax refund with the 2024 tax return then there are no penalties for filing the tax return after the due date.
If you have taxes owed on the 2024 tax return, those taxes have to be paid on or before April 15, 2025 to avoid a late payment penalty.
You can file an extension request so that you will have until October 15, 2025, but taxes owed still have to be paid on 04/15/2025. The extension is only for filing the tax return, not an extension to for the tax payment.
