In fact we should be reporting our monthly bitcoin income from signature campaigns, but who the hell does that? I would do it, but im too scared to get a penalty for not doing so earlier, and I also don't know what kind of proof they will demand, I just don't know what to expect, and nobody has clear answers for this, therefore I've resorted to holding it all until I have a clear vision of what we are talking about in this case.
It depends per country. I have been a freelancer for a good while, and haven't had one single time where the tax department required me to provide any proof. I recorded everything obviously, for in case they did ask for it, but it didn't happen. In some cases I had to pay like 50% in tax over all my earnings as freelancer, which is just insane. Don't get me wrong, I don't mind paying tax when reasonable, but this is a clear form of theft, and for that reason will never pay tax over my signature campaign earnings, and I'm sure others think alike -- just don't let greedy governments take away even more from you. Don't wake sleeping dogs....
Exactly, it really depends on what country you are in. For me, I've been in the freelancing business as well since 2009-2013, keeps everything documented, but governments didn't ran after me, so I guess I'm still good with my government.
But if they are going to look and have me paid my taxes, then I would be willing to do. What I hate is that my taxes are going somewhere else. Like to see it being used in projects that our people can benefit.
P.S. I also not reporting my signature earnings but everything can be tracked in blockchain.
