valid reasons for a late 990-EZ 2024 tax return by 4 months.  I prepared the 990-EZ late because I thought it was already filed on May 15, 2025 for 2024.  My client did not tell it was late but I should have know.  I use Pro series  basic for about 60 clients and use Pro series Professional for 5 clients.  When I open the clients I have to use Professional for 1120-S, 1040-NR and 990-EZ but the 990-EZ did not show on the first screen so I missed it,  all my fault. The penalty could be $3,000. 

Can you suggest a valid reason for a Penalty abatement,  if so thanks
