<prompt> Human: Hello friends - hope youre all doing well. I could use your advice please.In late 2014, a company that I used to work for was acquired, and I got a nice check for 31K in January 2015 for my stock options.I didnt report this in my 2015 taxes as I was really struggling financially at the time. I know this was incorrect. I cant - in good faith - plead ignorance here, as I knew what I was doing and was hoping it would go away I know....Yesterday I got a CP2000 notice from the IRS with the following fees: 5.5K taxes owed, 1K substantial understatement penalty, 300 interest.Thing is: I can afford to pay, I agree with the tax amount owed, and I dont believe I have a leg to stand on to waive the understatement penalty.I honestly just want to pay this today and move on with my life. But if I can get any feescosts waived by making a few phone calls, I would be dumb to not do it.Any advice? Im not wealthy enough to give away money because of morals but morally I feel like what theyre asking of me is quite fair.Thank you guys!  <response>: Penalties and interest are getting bigger and bigger. Pay for sure if you have the money!
