Bitcoin Tax Year & Filing Deadlines Explained 2018

Many people have started to buy and trade cryptocurrencies in 2018, some earning large amounts of money. What a lot of people have overlooked though is that they'll likely have to pay tax on these earnings, with reports of few Americans reporting their crypto holdings days before their April 17th tax deadline.

This guide will go through what is considered a tax year in various countries like the USA, UK, Russia & China; and when the submission/filing & payment deadlines are for each country.

We focus primarily on English speaking countries, as this is the language used by our current researchers, but we've also included countries with many users of our Crypto Coin Tracker (as we offer tax reporting functionality raising questions related to this guide).
