Do we Need Pay Tax for Mining for US Govt
Do you need to pay Taxes for US Govt for doing Bitcion Mining.?


You are not liable for income tax because:


You are not a US citizen and
You are not working in the USA.


Someone in the USA who is selling you a service might be required to charge sales-tax (though that sort of tax is often not applied to foreign sales). 


  Does Univted States TAx Revenue Board send the TAX Invioce on my Name


As far as I know, there is no USA government branch named "United States Tax Revenue Board".

The USA Internal Revenue Service (IRS) would not charge you personally for sales tax. So far as I know, US sales taxes are a state tax not a federal tax



Scams

When buying "mining services" be aware that, unless you have a really good understanding of how bitcoin mining works, you are likely to be the victim of a fraudster. 

One of the things fraudsters do is repeatedly invent superficially plausible (but actually false) reasons for you to send them money.
