What Is Convertible Virtual Currency and How It’s Taxed

Convertible virtual currency is taxed as property by the IRS, which means Bitcoin, Ethereum, and similar tokens generate a capital gain or loss almost every time you sell, trade, or spend them, and generate ordinary income when you receive them as pay, mining rewards, staking rewards, or airdrops. The label “convertible” applies to any digital token that has an equivalent value in real currency or can substitute for real currency, so it covers the tokens most people hold on exchanges. The taxation of convertible virtual currency follows the same framework used for stocks and other investment property, layered with a few crypto-specific reporting rules that have tightened significantly for 2025 and 2026.

What Counts as Convertible Virtual Currency

FinCEN defines convertible virtual currencies as media of exchange that either have an equivalent value in real currency or act as a substitute for real currency.¹ The practical test is whether the token flows in two directions: you can buy it with U.S. dollars and sell it back for U.S. dollars or another government-issued currency. That two-way exchange separates Bitcoin and Ethereum from points inside a video game or a loyalty program, which have no recognized market outside their own systems.

Because these tokens trade on public exchanges with real-time prices against the dollar, the government treats them as a financial resource worth tracking. If a merchant accepts the token for a physical product, it is functioning as money in that transaction, which is exactly the point at which tax consequences attach.

Why Property Classification Drives the Whole System

Under Notice 2014-21, virtual currency is classified as property for federal tax purposes.² That one decision means the rules that apply when you sell stock or real estate apply when you sell, trade, or spend crypto. Every disposal is potentially a taxable event that produces a capital gain or capital loss, calculated from what you paid to what you received.

There is no de minimis exemption for small transactions. A five-dollar coffee paid with Bitcoin technically requires you to compute the difference between the Bitcoin’s basis and its value at the moment of the purchase. The rule applies whether the amount is trivial or substantial.

Transactions That Trigger Tax

You owe tax when you:

Sell crypto for cash. The difference between your sale price and your cost basis is a capital gain or loss.
Trade one crypto for another. Swapping Bitcoin for Ethereum is treated as selling Bitcoin and buying Ethereum, and the sale side is taxable.
Spend crypto on goods or services. Buying a laptop with Ethereum produces a capital gain or loss based on how the token’s value changed since you acquired it.
Receive crypto through a hard fork or airdrop. Revenue Ruling 2019-24 treats tokens received through an airdrop following a hard fork as ordinary income at fair market value on the date you gain the ability to transfer or sell them.³

Several actions generally do not trigger tax: buying crypto with dollars and holding it, moving crypto between your own wallets, and giving crypto as a gift (with gift tax rules addressed separately below).

Mining, Staking, and Crypto Received as Pay

Tokens earned through mining or staking are ordinary income at the fair market value on the day you receive them.⁴ The tax hits at receipt, not when you eventually sell. Mine 0.5 Bitcoin on a day the price is $60,000 and you recognize $30,000 of ordinary income that year regardless of whether you keep or sell the coin.

That fair market value at receipt becomes your cost basis for a later sale. If Bitcoin has risen to $70,000 by the time you sell your 0.5 Bitcoin, your capital gain from the sale is $5,000, layered on top of the $30,000 you already recognized as income. Solo miners who treat the activity as a trade or business can generally deduct expenses like electricity and equipment. Stakers follow the same timing rule: the moment reward tokens hit your wallet with the ability to sell or transfer, the income clock starts.

Crypto received as payment for services or goods is likewise ordinary income at fair market value on the day received. When a token has no published exchange price, the IRS treats its fair market value as equal to the value of whatever property or service you exchanged for it.⁴ Receive an obscure token as payment for freelance work worth $500, and your basis in that token is $500.

Calculating Cost Basis and Choosing a Lot Method

Your cost basis is what you paid for a token, including transaction fees. Buy 1 Ethereum for $2,000 with a $15 exchange fee, and your basis is $2,015. Sell it later for $3,500, and your capital gain is $1,485.

If you have bought the same token at different prices, you need a method to determine which specific units you sold. The IRS allows two:

First-in, first-out (FIFO). Your earliest purchases are treated as the first ones sold. When prices have generally risen, FIFO produces larger gains because the cheapest lots go first.
Specific identification. You designate which units you are selling at the time of the transaction. To use this method, records must show each unit’s unique identifier, the date and time acquired, the basis, and the fair market value at acquisition.⁴

Specific identification lets you sell higher-cost lots first and shrink your gain, but the record-keeping burden falls on you. Without substantiation, the IRS defaults to FIFO. Notice 2025-07 provides temporary relief allowing certain taxpayers to rely on alternative identification methods for assets held by a broker, so it is worth checking whether your exchange offers compliant lot selection tools.⁵

Long-Term vs Short-Term Rates and the 3.8% Surtax

Hold a token more than one year before selling and any gain qualifies for long-term capital gains rates. For tax year 2026, those rates are 0%, 15%, or 20% depending on taxable income and filing status. A single filer pays 0% on long-term gains up to $49,450 in taxable income, 15% up to $545,500, and 20% above that. For married couples filing jointly, the 0% bracket extends to $98,900, the 15% bracket covers income up to $613,700, and the 20% rate applies beyond.⁶ Sell within a year of buying and the gain is taxed as ordinary income at your regular rate.

High earners face an additional 3.8% Net Investment Income Tax on capital gains from crypto sales when modified adjusted gross income exceeds $200,000 for single filers or $250,000 for married couples filing jointly.⁷ Those thresholds are not adjusted for inflation. Stacked on top of the 20% long-term rate, the effective federal maximum on crypto gains reaches 23.8%.

One planning note. The wash sale rule that blocks stock investors from claiming a loss when they repurchase the same security within 30 days does not currently apply to cryptocurrency, because crypto is property rather than a security. You can sell at a loss, buy back immediately, and still deduct the loss. Legislative proposals to extend the wash sale rule to digital assets have circulated for years, so this remains a moving target each tax year.

Reporting on Your Tax Return

Every Form 1040 asks a yes-or-no digital asset question: at any time during the tax year, did you receive (as a reward, award, or payment for property or services) or sell, exchange, or otherwise dispose of a digital asset? You must check one box regardless of whether any tax is owed. The same question appears on partnership, corporate, estate, and trust returns.⁵

Transaction detail goes on Form 8949. Each disposal gets its own line showing the asset description, date acquired, date sold, proceeds, cost basis, and resulting gain or loss.⁸ Digital asset transactions use specific box codes: G, H, or I for short-term sales and J, K, or L for long-term sales. The totals from Form 8949 flow to Schedule D, which combines short-term and long-term results and sends the final number to Form 1040.⁹ Mining and staking income typically goes on Schedule 1, or on Schedule C if you operate as a business.

Form 1099-DA and the New Broker Reporting Regime

Starting with transactions on or after January 1, 2025, digital asset brokers must file Form 1099-DA reporting your sale proceeds. Beginning with transactions in 2026, brokers must also report cost basis for certain sales.¹⁰ Whether you receive a 1099-DA or not, you remain responsible for reporting all digital asset income, gains, and losses on your return.¹¹

If a 1099-DA contains errors, contact the broker listed on the form to request a correction rather than the IRS. One current limitation matters if you have moved tokens between platforms: brokers cannot yet use acquisition information you transferred in from another platform to report cost basis. They can use that information only to determine lot ordering. Your own basis records may need to fill the gap.

Gifts and Charitable Donations

Giving crypto as a gift does not trigger capital gains tax for the donor. The recipient inherits your cost basis and holding period, so the tax event is deferred until they sell. If a gift to any one recipient exceeds $19,000 in value during the year, file a gift tax return (Form 709), though the lifetime exemption means most people will not actually owe gift tax.

Donating crypto to a qualified charity is often more tax-efficient than selling and donating the cash. Hold the token more than one year and you can generally deduct the full fair market value as a charitable contribution without recognizing any capital gain on the appreciation.¹² Buy Ethereum for $1,000, donate it when it is worth $5,000, and the deduction is $5,000 with no tax on the $4,000 appreciation. Held one year or less, the deduction is capped at your cost basis.

Crypto on Foreign Exchanges

Holding crypto on a foreign exchange can bring extra reporting obligations. The FBAR requires any U.S. person to file FinCEN Form 114 if the aggregate value of all foreign financial accounts exceeds $10,000 at any point during the year.¹³ Whether crypto held on a foreign exchange counts as a foreign financial account for FBAR purposes has been an evolving area, with FinCEN proposing rules that would explicitly include digital assets. FBAR penalties for willful violations can reach $100,000 or 50% of the account balance per violation, whichever is greater, so filing when significant value is held on a non-U.S. platform is the cautious path.

Records the IRS Expects You to Keep

The IRS expects documentation that can support every position on your return. For digital assets, that means keeping, for each transaction, the date and time you acquired each unit, your basis and the fair market value at acquisition, the date and time you sold or otherwise disposed of each unit, and the fair market value at disposal along with the amount of money or property you received.⁴

Download transaction history from every exchange you use, keep records of peer-to-peer trades, and note the dollar value at the time of any purchase made with crypto. Decentralized exchange activity and wallet-to-wallet moves often generate no third-party records, so you have to create them yourself. Reconstructing a year of trades across multiple platforms during filing season is where most reporting breaks down. Export regularly and store the data somewhere permanent.

Penalties for Underreporting

The IRS applies its standard penalty framework to crypto. The accuracy-related penalty for a substantial understatement is 20% of the underpayment, with an understatement considered substantial when it exceeds the greater of 10% of the tax that should have been shown on the return or $5,000.¹⁴ The 20% climbs to 40% in cases involving gross valuation misstatements or undisclosed foreign financial asset understatements.

Outright fraud carries far steeper consequences. Civil fraud penalties can reach 75% of the underpayment, and criminal tax evasion carries potential fines up to $250,000 and imprisonment up to five years. The IRS Criminal Investigation Division has pursued crypto cases actively, and blockchain analytics make transactions increasingly traceable. Checking “No” on the Form 1040 digital asset question when the answer should be “Yes” leaves a paper trail that is difficult to explain in an audit.
