The idea behind this project is good but it will contradict the purpose which bitcoin was made, no central authority and the likes purposes behind bitcoin creations will be defeated.
Bitcoin should be tax free.
The function of BitcoinFastTax is to enable the average person or company to simply and easily calculate their bitcoin taxes, which can't help but spur adoption because many legal uses for bitcoins are inhibited by the complex tax laws surrounding them. You are not in any way being further coerced into paying taxes by the mere presence of BFT. We are not an instrument of the IRS, nor are we opposing the spirit of bitcoin, we are simply a tool to help people calculate their bitcoin-related taxes if they need to, and so they know what the IRS knows. I know it may seem that our site complements the agenda of taxation, but that's a bit like blaming the weather report for the hurricane.

very funny however it seems your tool could be more useful to big exchangers that converts bitcoin to USD
