With the rapid advancement of blockchain technology, cryptocurrencies have become more mainstream than ever before. As the popularity of digital currency grows, so too does the interest of taxation authorities around the world. Cryptocurrencies are taxable entities and the taxation of income derived from the use of cryptocurrencies can be a complex undertaking. In the United States, the Internal Revenue Service (IRS) has made it clear that cryptocurrencies such as Bitcoin, Ethereum, and Litecoin are treated as property, not money, for tax purposes. Thus, any purchases of cryptocurrency or profits made from its exchange or sale are taxable. Taxpayers need to report any gains or losses incurred from their cryptocurrency investing activities, and should track and record all cryptocurrency transactions carefully. There are two basic types of taxes associated with cryptocurrency transactions: capital gains and income tax. Capital gains in cryptocurrency are taxed similarly to other investments. If a cryptocurrency is held for more than one year, then it is subject to long-term capital gains taxes; if it is held for one year or less, then it is taxed at the short-term capital gains rate. Income tax, on the other hand, is assessed on any sort of cryptocurrency earnings. This includes wages paid in cryptocurrency, mining rewards, and any other type of income earned from cryptocurrency holdings. In the United States, the IRS requires taxpayers to report any income received from cryptocurrency transactions on their income taxes. Recently, other countries have started to impose taxes on cryptocurrencies as well. In France, for instance, currency gains from cryptocurrencies are subject to a 19 percent flat tax, while mining activities are taxed at a 33.33 percent levy on the income produced from them. Similarly, in Germany, profits earned from cryptocurrency transactions are subject to up to 45 percent capital gains tax. Despite the growing complexity in the tax laws that govern digital currency transactions, it is important to remember that all cryptocurrency activities are potentially taxable. It is therefore wise to keep track of any cryptocurrency transactions and report them accordingly when filing taxes. By doing so, one can avoid any issues with the tax laws and ensure that taxes are paid accurately and in a timely fashion.
