Fewer than 100 out of 250,000 citizens, or 0.04 percent, who have filed federal tax returns this year to date via personal finance service Credit Karma reported cryptocurrency transactions to the US Internal Revenue Service (IRS), Reuters reported Tuesday, Feb. 13.

Credit Karma Tax General Manager Jagjit Chawla said that the company was not surprised about such a small amount of cryptocurrency filers since citizens “with more complex tax situations” usually tend to file later in the tax season. However, Chawla added that considering the rise of cryptocurrencies in 2017, the company “would expect more people to be reporting”.

The US 2018 tax filing season began Jan. 29 and the deadline to submit 2017 tax returns is April 17.

The IRS, which started providing guidance for taxation of Bitcoin in March 2014, treats cryptocurrency as property. As such, the IRS considers the purchase, sale, trade, and mining of cryptocurrency as taxable events.

Independent cryptocurrency trader Brandon Williams told CNBC that it would be more reasonable for him to treat cryptocurrencies as currencies since property status is “almost a deterrent in [the] pursuit of mainstream adoption”.

According to Williams, the tiny amount of cryptocurrency tax filings reported by Credit Karma points out “the difficulty in accurately reporting your crypto gains and losses”. Williams said that with more than two cryptocurrency tradings a day, it takes at least three or four hours every two weeks to record trading gains and losses, taking into consideration volumes and volatility.
