What the IRS Says Crypto Is, and Why It Matters

The concept

Since IRS Notice 2014-21, the United States has treated virtual currency as property for federal tax purposes, not as foreign currency and not as a security. The IRS has reaffirmed this position every year since, most recently through its digital asset guidance tied to Form 1040's "digital asset question" and the broker reporting rules phasing in for 2025–2026 tax years.

Why does one classification word change everything? Because the tax code already has a complete, well-tested rulebook for property: when you dispose of property (sell it, trade it, spend it, give it away) you compare what you received to what you paid for it (your basis), and the difference is a capital gain or a capital loss. That is the single idea this entire course builds from. It is also why crypto is not treated like cash: spending a dollar bill on coffee is never a taxable event, because a dollar's basis and its value are definitionally the same. Spending an appreciated bitcoin on coffee is a taxable event, because the bitcoin's value moved after you acquired it, and property rules require you to recognize that movement the moment you give the property up.

The property classification also explains why crypto does not get the favorable treatment cash or foreign currency sometimes receives, but does get two things ordinary income doesn't: a cost basis to offset proceeds, and — if held more than a year — preferential long-term capital gains rates (0%, 15%, or 20%, versus ordinary rates up to 37%). Compare this to collectibles (physical art, stamps, certain coins), which are also property but carry a higher 28% maximum long-term rate; some NFTs straddle this line, which Module 3 addresses directly.

One more consequence of the property rule: there is no "de minimis" exception for small crypto transactions in current law. A $5 coffee paid for in bitcoin is, mechanically, exactly as taxable as a $50,000 sale — only the size of the resulting gain or loss differs. Proposals to add a small-transaction exemption have circulated in Congress for years but have not become law as of this course's 2026 edition, so learners should track every disposal, however small, until the law changes.

Most US states piggyback on federal taxable income as their starting point for state income tax, so the property classification's downstream effects — basis, holding period, gain recognition — typically flow through to state returns as well, even though a handful of states and local jurisdictions have considered digital-asset-specific legislation of their own. This course focuses on federal rules throughout, but learners filing in a state with its own quirks should confirm whether their state conforms to federal crypto guidance or diverges from it before assuming the federal number is the final word.

The property classification also creates a recordkeeping duty that has no real analog for cash. Because every disposal requires comparing proceeds to basis, and because no single exchange sees your entire acquisition history (Module 4 covers this in depth), the IRS places the burden of proof for basis squarely on the taxpayer. If you can't substantiate a basis number with records, the IRS can — and in practice sometimes does, on audit — treat your basis as zero, turning the entire proceeds amount into a taxable gain. That single administrative fact is the real-world reason this course treats recordkeeping as a core skill rather than an afterthought bolted onto the end.

Worked example

Maria bought 0.01 BTC in January 2024 for $400 (basis = $400, or $40,000/BTC). In November 2026 bitcoin trades at $70,000, making her 0.01 BTC worth $700. She uses it to buy a $700 laptop.

Under the property rule, this is a sale of property for fair-market-value proceeds of $700, even though no cash touched Maria's bank account:

• Proceeds: $700 (fair market value of the laptop received)
• Basis: $400
• Gain: $300, long-term (held more than one year)

Maria owes capital gains tax on $300, exactly as if she had sold the bitcoin for cash and then separately bought the laptop. If bitcoin had instead fallen to $35,000/BTC and her 0.01 BTC were worth only $350, she would report a $50 capital loss — usable to offset other gains.

A second scenario shows the property rule working in the opposite direction. Marcus's father passed away in 2025, leaving Marcus 0.2 BTC that the father had originally purchased years earlier for a total of $8,000. Under the property rule's inheritance provision (expanded in Module 2.1), Marcus's basis is "stepped up" to the fair market value on his father's date of death — say $62,000/BTC — regardless of what his father originally paid. If Marcus sells shortly after at $63,000/BTC, he reports a small gain of roughly $200 on the full 0.2 BTC, not a large gain measured against his father's original $8,000 cost. The property classification is precisely what makes this stepped-up-basis rule available to crypto at all — it borrows directly from the long-established rule for inherited stocks and real estate.

Exercise

List six crypto activities from your own history (or a hypothetical history if you're new to crypto): for example, buying BTC with a bank transfer, staking ETH, trading SOL for USDC, spending crypto at a merchant, transferring crypto between two wallets you own, and receiving a crypto inheritance from a deceased relative's estate. For each one, write a single label:

1. Property acquisition (basis starts here, nothing taxable yet)
2. Property disposal (compare proceeds to basis — capital gain or loss)
3. Income (fair market value received is ordinary income immediately)
4. Non-event (no tax consequence — e.g., moving your own coins between your own wallets)

Check your labels against this rule: if you gave up an asset you owned to get something else of value, it's a disposal; if you received something new without giving up an asset you already held, it's income; if you only moved assets you already own between accounts you control, it's a non-event. For the inheritance item, note that it is an acquisition, but with a special basis rule — fair market value on the date of death, rather than any carryover amount — worth flagging separately even though it still falls in the "acquisition" bucket.

Recap

• The IRS treats all virtual currency as property, so general capital-gains rules (basis vs. proceeds, holding period) apply to every disposal, no matter how small.
• Spending, trading, or gifting crypto is a disposal of property that can trigger gain or loss — it is never tax-neutral the way spending cash is.
• Classify every crypto action as an acquisition, a disposal, income, or a non-taxable self-transfer before you try to calculate anything; getting the classification right — including special basis rules like inheritance step-up — is the foundation for every later lesson in this course.
