Crypto has gone mainstream, and the IRS is taking notice
Digital assets moved from the fringe into ordinary brokerage accounts, and the IRS followed. It now gets far more data about what you buy and sell. Here is what changed, and what it means for your return.
Cryptocurrency started on the fringe. It is now held by tens of millions of Americans, spot bitcoin and ether ETFs trade through ordinary brokerage accounts, and stablecoins settle real payments every day. As it went mainstream, the IRS paid closer attention. If you hold or trade digital assets, the agency sees more of that activity than it did a few years ago, and it expects to see it on your return.
Crypto is property, and has been since 2014
The IRS answered the basic question in 2014: for federal tax purposes, virtual currency is treated as property, not currency. That one choice drives the rest. Selling crypto, trading one coin for another, or spending it are all dispositions that can produce a capital gain or loss. Getting paid in crypto is ordinary income at its value on the day you receive it. None of this changed as the market grew. It was enforced loosely at first, and many holders read the quiet as permission to skip it.
The 2019 letters were the turning point
In the summer of 2019 the IRS mailed more than 10,000 letters to people it believed held crypto. They arrived in a few versions. Letters 6174 and 6174-A were educational: read them, check your past returns, and correct anything that was off. Letter 6173 required a written response by a set date. The agency also sent CP2000 notices, which propose a specific change to a return when third-party data does not match what was filed. A CP2000 gives you a short window to agree or disagree before a Notice of Deficiency follows.
Reporting has caught up to the market
The bigger shift is in what the IRS can see. For years, exchanges sent little, and the forms that did go out, such as the 1099-K, showed gross payment volume rather than gains or losses. That gap is closing. Starting with the 2025 tax year, custodial brokers such as U.S. centralized exchanges report gross proceeds from sales on a new form, the 1099-DA. The first of those forms reached taxpayers and the IRS in early 2026, and cost-basis reporting phases in for later years. In practice, the agency now receives a running record of the sales you make on major platforms.
The question you answer every year
There is also a question you answer whether you trade or not. Near the top of Form 1040, above your income, the IRS asks whether you received, sold, exchanged, or otherwise disposed of a digital asset during the year. You sign the return under penalty of perjury, so a careless "no" is hard to walk back later. Answer it based on what you actually did.

None of this makes crypto taxes harder than they need to be. It does remove the option of ignoring them. A few steps keep you out of trouble:
- Keep records as you go. Dates, amounts, cost basis, and proceeds for each disposal. Exchange exports and wallet history are easier to pull now than to rebuild three years from now.
- Report dispositions on Form 8949 and Schedule D. A 1099-K or 1099-DA is a starting point, not your gain or loss. You still calculate basis.
- Answer the Form 1040 digital asset question honestly. It sits in plain sight, above your income, and you sign under penalty of perjury.
- Fix prior years before a letter arrives. Amending on your own is cheaper and cleaner than answering a notice.
- Get specialized help when it is messy. Several exchanges, staking, or DeFi is where general preparers still get it wrong.
Crypto going mainstream cut both ways. The tools are better and the rules are clearer than they were in 2019, but the IRS is also watching more closely and holding more of your data. Reporting accurately now costs far less than untangling a back-year problem after a notice shows up.
