Cryptocurrency Tax Rules Explained

Here's the clean mental model for cryptocurrencies and taxes: two buckets cover almost everything. First bucket: capital gains and losses. If you hold a token as an investment and later dispose of it, you generally have a capital gain or loss. Hold it more than a year and it's typically long-term; hold it a year or less and it's typically short-term, taxed at ordinary income rates. Most long-term net capital gains fall into preferential federal rates of 0%, 15%, or 20% depending on taxable income.

Second bucket: ordinary income. If you receive crypto as compensation or as rewards you can control, you're generally looking at ordinary income at the fair market value in USD at the time you receive it. That income then becomes your cost basis for the units you received—meaning you can get taxed again later when you dispose of those units, this time as a capital gain or loss.

A fast way to pressure-test your activity is to separate owning from earning. Buying and holding is usually boring from a tax standpoint. Earning—staking, mining, getting paid, receiving an airdrop, or receiving tokens that hit your wallet as a reward—creates reporting work immediately. The distinction between passive holding and active income generation defines most tax outcomes.

Cost basis is the lever that most often gets mishandled, especially by active traders. When you buy the same asset at multiple prices, you own multiple lots, each with its own basis and acquisition date. When you sell, you must decide which lot you sold. Many platforms default to FIFO—first in, first out—but default is not the same as optimal, and it's not the same as documented.

The IRS expects you to maintain sufficient records to support positions on your return. Think date and time of each transaction, the USD value at the time, and what you received and gave up. A concrete example makes this real. Suppose you bought 1 ETH for $2,000, and later you swapped it for $3,000 of USDC on an exchange. Even though you never touched a bank account, you disposed of ETH.

Your gain is generally $1,000—the $3,000 amount realized minus $2,000 cost basis—usually reported as a capital gain. If you later spend that USDC on a laptop, that spend can be another taxable event if the USDC wasn't exactly $1 per unit at acquisition and disposal, and fees can complicate it. Crypto is property; property creates a paper trail.

Recent reporting changes raise the stakes. Beginning with sales of digital assets effected in calendar year 2025, custodial brokers—exchanges and other intermediaries that take possession of customer assets in covered transactions—are required to file information returns on Form 1099-DA reporting gross proceeds. Taxpayers generally receive corresponding statements in early 2026 for 2025 activity.

Cost basis reporting is also phasing in. In broad terms, brokers' basis reporting obligations expand for certain transactions starting with 2026 sales, and covered security treatment generally keys off assets acquired after 2025 in custody. This matters because proceeds-only reporting can still leave taxpayers with the hard part: reconstructing basis across multiple transfers and platforms.

Losses are where crypto can help—or hurt—your broader tax picture. Capital losses can offset capital gains, and if losses exceed gains, individuals can generally deduct up to $3,000 per year against ordinary income, carrying the rest forward. This is where taxes cryptocurrency strategy often shows up as year-end loss harvesting.

But one critical nuance: the wash-sale rule generally applies to securities, and cryptocurrency has typically been treated as property rather than securities for this purpose under current law and guidance. Many traders interpret that as a green light to sell at a loss and buy back immediately. The smarter interpretation is narrower: the classic wash-sale statute may not apply, but anti-abuse doctrines and plain audit skepticism still exist, and facts matter.

Business activity adds another layer. If you're getting paid in crypto as an independent contractor, that's generally reported as business income, often on Schedule C, with self-employment tax potentially in play. If you're an employee paid in crypto, the wages are still wages—just denominated in property that must be valued in USD when paid. The crypto part doesn't replace the payroll part.

There's also a compliance rule that keeps resurfacing in market chatter: the $10,000 reporting threshold for cash payments in a trade or business under Form 8300. Congress amended the statute to include digital assets in the definition of cash, but as of July 2026, the IRS has stated that until implementing regulations are issued, businesses are not required to include digital assets when determining whether they've received more than $10,000 for Form 8300 purposes.
