I don't see the problem here? Work for bitcoin! You going to buy it anyway. You don't have to cash it out into fiat, you could just cashout a small amount and pay tax on that and buy everything else with bitcoin if you can. Keep your Bitcoin don't sell it for fiat.
Im a web developer/designer and wondered if its worth getting paid in bitcoin? Im from the UK and not sure how it would work in terms of the end of year tax return.
I mean what would you be losing out on, really? It might be worth it if the value continues on a bull run.
As for UK tax laws, I would assume that, and don't quote me since I am not a UK tax law expert, you would note down the value of the bitcoin when you receive it, and then whatever price you sell it for, either with capital gains or capital loss due to normal volatility, would be the portion that is taxed. One part being the "normal" salary, the work you were paid for, and then capital gain/loss being whatever changes from that point for your Bitcoin. Now, as I said, I don't know. I don't think that the UK has tax laws defined for something as specific as that.
But it probably wouldn't hurt much to accept part of your salary in Bitcoin.
Then you will have to prove when you received your Bitcoin and what price it was. You will have to give your wallet info and transactions. What will they do with that? Nothing because they don't know about how bitcoin works. So I'm not sure how you would make a tax deduction on that. Then when you need to prove your losses in altcoins ect how at you going to do that? Why don't you just keep the Bitcoin and use it as it is intended why would you want to swap it for ancient banking technology?
