Key takeaways

  • Not reporting your cryptocurrency on your taxes can lead to fines, audits, and other penalties.
  • If you haven’t reported your cryptocurrency in the past, you can file an amended tax return. 
  • Filing an amended tax return isn't likely to increase your risk of an audit — the IRS is more lenient with taxpayers who make a good-faith attempt to report all of their income.

If you haven’t reported your cryptocurrency on past tax returns, you still have time to submit a tax amendment and reduce your risk of an audit. 

In this guide, we’ll break down a simple step-by-step process for submitting a crypto tax amendment. But first, let’s break down what can happen if you decide not to report your cryptocurrency. 

How is cryptocurrency taxed? 

In the United States, cryptocurrency is subject to ordinary income and capital gains tax.

What happens if you don’t report cryptocurrency on your taxes? 

It’s important to keep in mind that blockchains are distributed public ledgers, meaning anyone can view the ledger at any time. Figuring out an individual’s activities on that ledger essentially comes down to associating a wallet address with a name.

In the past, the agency has worked with contractors like Chainalysis to analyze blockchain transactions and identify ‘anonymous’ wallets.

What should I do if I forgot to report my crypto taxes in the past? 

What should you do if you already filed your tax return, but you forgot–or didn’t know you had to–report your cryptocurrency gains on that return? The best idea is to amend your tax return from whichever year(s) you didn’t include your crypto trades. 

You have three years from the date that you filed your return to file an amended return. 

Some investors fear that submitting an amended return may increase their risk of a future audit. However, the IRS is known to be more lenient to those who make a good-faith effort to properly pay their taxes.

How to submit an amended tax return 

If you’ve forgotten to report cryptocurrency on your taxes,  you can follow this 3-step process to submit an amended tax return. 

Step 1: Calculate your tax liability

Step 2: Complete Form 1040X 

Step 3: Mail or e-file your amended tax return

Step 1: Calculate your tax liability

The first step to submitting an amended tax return is figuring out your tax liability.

To calculate your tax bill, you’ll need to calculate your capital gains and income from cryptocurrency during the tax year. To do this, you’ll need accurate records of your cryptocurrency disposals and income events.

If you're having trouble calculating your tax bill, crypto tax software can help. Just connect your wallets and exchanges and let the platform generate a complete tax return in minutes!

Step 2: Complete Form 1040X

Once you have determined your tax liability, you should download a current IRS Form 1040X, Amended U.S. Individual Income Tax Return. This form comes with easy-to-follow instructions and requires you to only include new or updated information.

Step 3: Mail in or e-file your amended return

Once you’ve finished amending your tax return, you can mail it to the IRS. Before sending, you should make sure that you’ve attached all necessary forms and supporting documents. In addition, if your amendment results in a higher tax bill, you should include the additional tax payment with the return. 

Once you’ve submitted your amended return, it’s important to be patient. In usual times, it takes the IRS 8–12 weeks to process your amendment. Due to delays from COVID-19, the IRS states that the process could now take longer than 20 weeks. 

If you’re wondering whether your tax return has been processed, you can check its status online using the IRS’s ‘Where’s My Amended Return?’ tool.
