Hello, sorry was busy for most of the day taking a CPA exam so I don't think I have full quotes to respond to but I will try and summarize everything as best I can since I did work at a firm that was similar size to Grass CPA (although not the same state).
First things first, DO NOT CONTACT THEM AT ALL, about anything Phil related. I doubt they are licensed by the PCAOB so the only people they would be legally forced to tell any info to is under a subpoena. Calling them just gives Phil the narrative that trolls are harassing him irl and we have touched enough poop already.
Second, normally with a small business like this, the accounting firm would want to be in charge of bookkeeping services so that the taxes are easier and they can consult based on business trends they notice. Now if the $297 for charges didn't already tip you off then Phil's basic nature should have told you that "He has a business degree dood and he can do that himself." So the accountants are probably coming at this somewhat blind but not dumb. They would require some sort of proof or backing as to where the expenses are coming from. I have had plenty of tax returns that I have filled out where we needed proof of a $15 dollar donation to goodwill before reporting it, so these guys who live and breathe small time tax returns would be all over him if he tried pawning off these thousands of dollars of charges they would instantly demand proof. $297 is not worth losing a CPA license over, trust me on this (getting the license is proving to be a year and a half of work and no social life).
Third, in order for Phil to even consider these as business expenses, he would need to play WWE Champions almost exclusively on stream. Right now, things I would consider business expenses he could write off would be the games he buys, his internet bill, electricity or its equivalent, and depreciation expenses on his computer, laptop, and whatever games he plays. But I doubt he is even getting the depreciation expense right since MACRS is a bitch to follow and it requires effort.
Fourth, creating an LLC is way too much time and money for Phil to ever do. He would need a registered agent in Washington, file a certificate of formation with the secretary of state in Washington, create an operating agreement (although its not needed for washington), and then get an EIN. On top of that, the LLC needs to fill out its own tax returns which means paying Grass more money for different tax returns and probably having them insist on doing Phil's bookkeeping as well. Which means more eyes on his finances, which he is paranoid of as we have seen, and more payments to something that isn't Doordash, booze, or WWE Champions.
If I missed anything or if there are other questions, I can try and respond best I can in between studying for REG and praying as hard as possible that I don't have to take AUD again in between this fun busy season
