But if people's income is bitcoin, then the tax payment will be different. It is possible that people do not pay tax for bitcoin income. FINCEN regulation already said that if you purchase goods/services directly with your bitcoin, you don't need to pay tax. It means if you hold your coins for a couple of years and you can buy much more things with the same coin and you don't need to pay any tax even the bitcoin's purchase power increased many folds
Where did you get that from? There are different kinds of taxes that apply to bitcoin.
Taking germany as an example you'd have to pay income tax when you receive your income in bitcoin. You have to pay VAT tax on stuff you produce even if you sell it for bitcoin. You have to pay capital gains tax if you speculate on the value of bitcoin and sell some for a higher price than you bought them for (except if you held them for 1 year). Some even say you have to pay VAT (19% currently) when you sell a "commercially" mined coin.
Even barter is taxed: If a customer buys some product from a company paying with a bitcoin, the company has to pay VAT (in EUR, of course, essentially selling the product for EUR after buying the bitcoin from the customer) and the customer might have to pay capital gains tax (because he just sold a bitcoin) depending on wether or not he held the bitcoin for over a year and what price he had bought it for initially.
Bitcoin isn't somehow tax-free, get over it. It might be easier to hide and cheat, but this is nothing new for tax authorities and companies having to declare taxes and having to have their books in order will go a long way insuring bitcoin income and sales are being properly taxed.
I'm no fan of taxes and/or the state, but this is the reality at the moment.
That is my misunderstanding about the regulated money transmitter, I thought that has something to do with tax
Anyway, tax in bitcoin is totally new for tax authorities, because the value for coin can vary a lot during a fiscal year. I remember that when it comes to foreign assets, normally a tax declaration require an exchange rate at the end of the fiscal year. If a company earned some bitcoin at the beginning of the year but at the end of the year the coin price rised by 10 times, he had to pay 10 times more tax on the same sale, this is not practical
I think all of today's tax system are based on fiat money (which have a stable value over at least a year), if a volatile money like bitcoin comes out, those officials might need to charge the income tax each week, but that will break all the existing accouting and tax reporting procedures
