You said this is the 2nd year in a row so something must have changed from the previous years that is now causing you this problem.

Thats expensive for a CPA at least in my area.

Don't forget though......the non-payment penalty can be waived as soon as the actual tax amount is paid in full. I was thankful I got the IRS to wAive the initial penalty with a letter from our Pdoc & talked to thevIRS advocate who let me know the other penalty can be requested to be waived as soon as the tax is paid. They don't offer that information.....something you might look into to at least save you some.

Hope you have learned the cause of this problem so you don't have a 3rd year like this.

Dealing with the IRS personally was a serious challenge especially after the H I left had totally ignored the 1st letter from the IRS & never told me about it. When I DEMANDED an explanation he said he didn't understand the letter & couldn't find a copy of the taxes he had filed so he just didn't bother. I found out when I had the mail forwarded to my farm that winter & got the 2nd IRS letter in Feb the day before my birthday saying there had been no response to the 1st letter the previous March. Good thing there was 2100 miles between us. It took me several months to sort it out too & understand what was going on with the IRS Who actually was a good help......but they can be frustrating too like waiting over an hour for the call to go through to talk to someone then the cell call gets dropped.....or I got one guy who had a thick German accent who couldn't grasp what I was asking. Finally demanded a supervisor.

Hope you don't have to deal with issues like that.
