Yes. It's too late to file for an extension now. The deadline was May 1, 2025, per the IRS.
However, if you are getting a refund for TY24, then you won't face any penalties or interest for late filing. You must file within 3 years to claim the refund.
If you owe taxes for TY24 then you'll want to file as soon as possible, because penalties and interest are accruing.
