Hypothetical question

Using a throwaway bc my boss knows my main. Quick background on my situation — any input appreciated.

S-Corp election deadline missed. I've been dealing with this for about 2 months now and the situation isn't improving.

I have already done some research online but the other party is not cooperating.

What are my legal options here? Is it worth pursuing?

Illustrative response

Went through this 6 months ago. My advice: be persistent but professional. Companies count on you giving up. Send follow-up letters every 2 weeks or whatever, reference your original complaint, and escalate to a supervisor each time. Squeaky wheel gets the grease tbh.
