IRS Sending Out Thousands More Cryptocurrency Warning Letters

The IRS has begun sending out warning and action letters to suspected cryptocurrency holders similar to the 10,000+ letters they sent at this time last year (August 2019). Letters 6174 and 6173 are two different variations that alert suspected crypto holders of their tax reporting requirements.  

The below images have been taken from reddit over the past week. As seen, a number of individuals are receiving variations of these letters.

6174 Cryptocurrency Letter

The variations of letter 6174 are no action letters, meaning they do not require a response. If you have met all the crypto tax filing obligations outlined in the letter, you have nothing to worry about. The letters are simply designed to educate the recipient.

If you have not met all of your filing requirements, you should do so and amend any prior years tax returns that did not include your crypto-related gains, losses, and income.

6173 Cryptocurrency Letter

Letter 6173 is more serious, and it requires a response. You are required to respond to the letter by the date specified within. If you do not respond to the letter, your tax account will be examined by the IRS.

If you received Letter 6173, you have some options for responding:

  1. Properly file the missing tax returning including your virtual currency transactions
  2. Amend your prior years tax return if you did not properly report your cryptocurrency transactions
  3. Or, if you believe you filed your cryptocurrency taxes correctly, respond to the IRS with a written letter explaining how you arrived at the income reported

Crypto Taxes Overview

The IRS treats cryptocurrencies as property for tax purposes, not as currency. Just like other forms of property—stocks, bonds, real estate—you incur a tax reporting requirement when you sell, trade, or otherwise dispose of your cryptocurrency for more or less than you acquired it for. 

For example, if you purchased 0.1 bitcoin for $2,000 in June of 2020 and then sold it two months later for $3,000, you would have a $1,000 capital gain. This gain needs to be reported on your tax return, and depending on what tax bracket you fall under, you pay a certain percentage of tax on the gain. Rates fluctuate based on your tax bracket as well as depending on whether it was a short term vs. a long term gain. This applies for all cryptocurrencies.

Alternatively, if you sold your cryptocurrency for less than you acquired it for, you can write off that capital loss to save money on your crypto taxes.
