Tips for cryptocurrency investors in a tough tax year

A crypto tax bill rarely comes from the thing people expect. It comes from activity that does not feel like a sale, such as swapping one coin for another, spending crypto at checkout, or earning it. The rules below are what actually decide what you owe, current as of 2026, along with the records that make a busy trading year answerable instead of alarming.

The pattern is consistent once you see it. The IRS treats crypto as property, taxes most of what you do with it, and already receives data from exchanges. What you report has to line up with what the agency sees.

Most transactions are taxable, not just cashing out

Selling crypto for dollars is the obvious taxable event. The ones people miss are the rest. Spending crypto to buy something is a sale of that crypto. Trading one coin for another is a sale of the first coin, even though no dollars ever hit your bank account.

Say you bought Bitcoin at $9,000 and later used it to buy a different coin when the Bitcoin was worth $10,000. You owe tax on that $1,000 of gain in the year of the trade. A second taxable event happens when you sell or spend the coin you bought. On exchanges that price everything in other cryptocurrencies rather than dollars, these events pile up quickly and are easy to lose track of.

Capital gains rules set the rate

Because crypto is property, gains and losses follow the same capital gains rules that apply to assets like stock or real estate. The rate turns on how long you held the coin before disposing of it. Hold it a year or less and the gain is taxed at your ordinary income rate. Hold it longer than a year and it usually qualifies for the long-term rate of 0, 15, or 20 percent, depending on your income.

That one-year mark is worth checking before you sell. The identical trade can carry a very different tax cost depending on which side of the line you land on.

A losing year can still leave you with tax

Gains are taxed in the year you realize them. If you sold at a profit in the spring and the market fell later in the year, the spring gain still counts. The later drop only helps you if you actually sold into it and locked in the loss.

Capital losses offset capital gains dollar for dollar. When losses run past gains, you can apply up to $3,000 against ordinary income in a year and carry the rest forward to future years. Individuals cannot carry a capital loss back to an earlier year. So a profitable stretch followed by a crash you held through without selling can leave a real bill.

The wash-sale question

The wash-sale rule that stops stock investors from claiming a loss and rebuying within 30 days was written for securities. As of 2026 the IRS treats crypto as property rather than a security, so that rule does not clearly reach it. Congress has proposed closing this gap more than once without passing it, so treat it as current law and not a permanent fixture.

Cost basis is your job, and the tracking rules changed

Your gain is the sale price minus your cost basis, which is generally what you paid plus fees. Proving that basis falls on you. Without records, the IRS can set your basis at $0 and tax the full proceeds, which is far more than you actually made.

Two changes matter for a 2026 filing. Starting January 1, 2025, you track basis per wallet or account instead of pooling everything you own into one running total (Rev. Proc. 2024-28), so your records need to be organized by account. And exchanges began issuing Form 1099-DA for 2025 activity. Early versions report gross proceeds, with cost basis reporting phasing in later, so the number an exchange sends the IRS may show what you sold for without subtracting what you paid. If you cannot supply the basis, that gap reads as taxable income on paper.

Mining and staking are income first, then capital gains

Coins from mining are ordinary income at their fair market value on the day you receive them. That same value becomes your cost basis. When you later sell those coins, you have a capital gain or loss measured from that basis. Staking rewards work the same way and count as income once you have control over them and can move or sell them (Rev. Rul. 2023-14). Airdrops and crypto paid to you for work also land as ordinary income at receipt.

The IRS already asks, and already has data

Every Form 1040 carries a digital-asset question near the top, asking whether you received, sold, exchanged, or otherwise disposed of a digital asset during the year. You have to answer it, and answering falsely carries its own consequences.

Behind that question, the IRS collects records through court-ordered summonses to exchanges and now through 1099-DA reporting. When what an exchange reports does not match your return, the mismatch can produce a notice such as a 6174, a 6173, or a CP2000. Keeping full exchange exports and wallet history, with dates and dollar values, is what lets you answer one of those in a week instead of a month. The IRS can question returns going back several years, so those records need to outlast the filing itself.

Before you file

1. Pull everything. Full transaction history from every exchange and wallet for each year involved, not only the accounts you used most.
2. Rebuild basis by account. Match each disposal to what you paid for that specific lot, tracked per wallet, since the pooled method no longer applies.
3. Split income from gains. Mining, staking, airdrops, and crypto pay are ordinary income. Sales and trades are capital gains. They report on different parts of the return.
4. Answer the digital-asset question honestly. It sits on page one of the return for a reason.
5. Get help if the year is heavy. High trade counts, DeFi, or missing basis are the cases where filing alone tends to cost more than it saves.

These rules are settled enough that most crypto returns are answerable with good records. The expensive outcomes come from thin records and unanswered notices, not from the trading itself.
