Bitcoin in its own state is not taxable as if you were having 1 bitcoin in this year the same in next year then there is no tax applied to it, but suppose you sell those coin for capital gains then yes it is taxable,but for this trade also there is another route in which you don't have to pay taxes on capital gains, all you have to do is skip the exchange and do the trade in person for cash and there will not be any official record of that transaction taking place so you don't have to pay any tax on this but it will become your black money and you would have to find a way to make it legitimate on your own.

Bitcoins in many places has no taxation implemented so far. Maybe they find difficulties to manipulate the circulation of bitcoin due to its highly secured and  encrypted, Or maybe they are out of control on online jobs so far, It was advantageous to our part as bitcoin holders whom we are exempted with taxes. But for safety precautions like scammers and hackers its a big threat for us . If ever we are victims of that kind of crime, We took hardly find ways to recover because of its not legally secured.

I hope the taxable bitcoin, so this becomes the first door to legalized by the state, it is time for the tax council to think about this so that it can increase the state income from bitcoin.

when your country hasn't allowed it as a legal currency then it should not be taxable. how can you pay the tax if that is not any registered? so I think Bitcoin is not taxable, but when you are going to withdraw your cash from Bitcoin then you have to pay the least amount of fee. that's it.

in my country BTC is not Taxable dont know about other countries

I can see that when Bitcoin etc becomes more widely accepted and mainstream that governments will jump on the chance to tax it. Not seen any real ways that they would do this and implement it but i can see it happening

edit: i am in the uk and just came across this https://www.gov.uk/government/publications/revenue-and-customs-brief-9-2014-bitcoin-and-other-cryptocurrencies/revenue-and-customs-brief-9-2014-bitcoin-and-other-cryptocurrencies

Although Bitcoin may be used like fiat currency is used, Bitcoin and digital currency in general, aren’t considered to be money (legal tender) by most countries' taxation systems. In fact, they are considered to be personal property, like gold, silver or corporate stock.
Unless your business is buying or selling Bitcoin, they are a capital asset. In the US, profits are taxed at capital gains rates. Losses are deductible only if Bitcoin is used for business or investment purposes (with investment losses being limited to $3000 annually).
When it comes to other countries of course, it is down to local policy. Keep in mind that cryptocurrency is relatively new to most economies with governments scrambling to regulate it as well as trying to tax it. Policies are bound to keep changing, so it’s best to complete a thorough investigation locally before jumping to conclusions or proceeding with a business plan or an investment.

Bitcoin is taxable and is taxavoidable in the same time. As long as your have your bitcoins in the wallet, or if you pay with bitcoins you are safe from the taxes. As long as you pay out from the exchange and transfer it to the bank you could be fined for not paying your income tax that you have gained on speculating activities.

That is so in most countries at least. Btw... most income taxes are actually illegal in the international law. But that is the subject for whole another issue.

As of now, in the case of my country, Bitcoins are not YET taxable. I said "yet" because I consider this is one of the risks of Bitcoin, that sooner or later the government will butt in and impose regulations and tax in Bitcoin trading.

I know this because the government will never let itself be left behind especially if they will see the potential return on investment that Bitcoins can give to the investors. But actually, imposing tax will be the least they can do. Because there is also a worst scenario that instead of imposing tax, they might ban Bitcoin totally.
