I think in a lot of cases though, the gov is going to lose money. If someone is actually running a business, they should pay tax appropriately of course. For someone like myself(and I assume the majority of folks here), if I were to get pushed on this issue and I included all my buying and selling outside Reverb, I could easily show a sizeable loss. My total transactions increased this year because I bought and sold some gear that if we weren't in a pandemic I would have just tried and maybe not bonded with at a brick and mortar store. I got the form in question as well for a total of ~$300 on Reverb. I plan to ignore it, but if the IRS were to question me on it, I'd claim all the things I bought and sold(as a hobbiest) here on TB, on Craigslist, etc...So the $300 guitar head I sold on Reverb, I actually had bought locally on offerup for $325. I also bought a new telecaster from GC and figured out I wasn't really a tele guy, and sold it for a loss on Craigslist. Repeat many times. In the grand scheme it's all chump change so if they come at me about the $300 "capital gains", them and me will have a bunch of extra work and my quick estimate is that including shipping charges and everything I could easily show a $500 loss for 2020, probably more. Adds more complication when this crosses years. So, how about the bass I sold for $600 in 2020 that I bought for $500 in 2010? Also, why pick on musical instruments? I bought and sold a number of pieces of home fitness equipment last year. I sold a bench that I bought a few years ago at a profit in 2020, but I bought a Smith machine to replace it and paid a mint since home fitness is of course all the rage right now. And what about the mattress I bought online in 2020 for $400 and it was way too soft that I ended up selling on CL for $100? I get collecting taxes from a business, but how do they do this across platforms, and across different hobbies for people just buying and selling things for their personal use? If Reverb has to report this, how is it fair that Talkbass doesn't have to report these exact same type of transactions?
