If you invest in cryptocurrency, you could face scrutiny from the IRS in 2021. The IRS has made clear that it is paying attention to cryptocurrency investors, and that it will be vigorously enforcing investors’ reporting and payment obligations in the year to come.

It’s tax season. You’re working on your 2021 tax returns, and you just realized that you made a mistake in a prior year. What should you do? As Washington D.C. tax lawyer Kevin E. Thorn, Managing Partner of Thorn Law Group explains, your options will depend on the specific mistake you made, how much you might owe and a variety of other factors.

When it comes to preparing your annual income tax returns, mistakes can be costly. The IRS scrutinizes individual and corporate filers’ returns, and it audits and investigates taxpayers suspected of underreporting their federal income tax obligations. With this in mind, you need to be careful when preparing your (or your business’s) returns for the 2020 tax year—and you should consult with a Washington D.C. tax attorney if you have questions or concerns about potential filing issues or liability.

The IRS began a heavy push to target Bitcoin and other cryptocurrency investors in 2019, and it has recently made clear that it will be continuing this push in 2021. After sending several rounds of “warning letters” to cryptocurrency investors over the past two years, the IRS will be shifting its focus to enforcement going forward.
