Crypto Tax vs Stock Tax 2026: 7 Key Differences That Cost You Money

Both are capital gains — but the rules diverge in ways that can save or cost you thousands. Here's what stock investors need to know before filing crypto taxes.

You've been filing stock taxes for years. Dividends on Schedule B, capital gains on Schedule D, 1099-B from your broker with cost basis already filled in. Simple enough.

Then you bought some crypto. You figure it's the same thing — capital gains, same forms, same rates. And honestly, the headline is similar: long-term capital gains rates (0%, 15%, 20%) apply to both, and short-term gains are taxed at ordinary income rates for both. The form is the same (Schedule D + Form 8949).

But the details diverge in ways that can cost — or save — you thousands. If you're applying stock tax logic to crypto, you're probably making at least two mistakes. Let me walk through the seven differences that matter.

1. Wash sale rule: the biggest crypto advantage

With stocks, if you sell at a loss and rebuy the same security within 30 days, the loss is disallowed — you can't claim it. This is the wash sale rule under Section 1091, and it prevents "harvesting" losses without actually exiting the position.

Crypto, as of 2026, is not subject to the wash sale rule. The IRS classifies crypto as property, not a security — and Section 1091 applies specifically to "stock or securities." You can sell BTC at a loss today, rebuy it five minutes later, and claim the loss on your taxes.

This is a massive tax advantage that stock investors don't have. If your portfolio is down and you want to realize losses to offset gains, crypto lets you do it without changing your position. Stocks don't.

However: this loophole is under active legislative pressure. Multiple bills have proposed extending the wash sale rule to crypto. If you're planning a tax-loss harvesting strategy, don't assume the rule will stay this way forever. Our detailed guide to the crypto wash sale rule covers the current status and proposed changes.

2. Cost basis tracking: you're on your own

When you sell a stock, your broker reports both the proceeds and the cost basis on Form 1099-B. The IRS gets a copy. You just copy the numbers onto your return.

Crypto is different. Starting in 2026, exchanges issue Form 1099-DA — but this form reports proceeds, and cost basis only for assets acquired on that same exchange. If you bought BTC on Coinbase, moved it to a hardware wallet, then sent it to Kraken to sell, Kraken's 1099-DA shows the proceeds but leaves basis blank.

You're responsible for tracking and proving your own cost basis. If you can't, the IRS may treat it as zero — meaning your entire sale proceeds are taxed as gain. This is the phantom-tax problem we covered in our wallet-to-wallet transfer guide.

With stocks, the broker handles this for you. With crypto, the burden is entirely on you. This is the single biggest practical difference for taxpayers.

3. Crypto-to-crypto trades are taxable

Selling Apple stock to buy Microsoft stock is a taxable event — you realize the gain on Apple. But stock-to-stock trades through a broker are well-defined: the broker handles the cost basis tracking and reports it cleanly.

Crypto-to-crypto trades are also taxable under IRS FAQ Q16. Swapping ETH for BTC is a taxable disposal of ETH. But unlike stocks, you're responsible for tracking the cost basis across wallets, exchanges, and chains. There's no broker doing this for you.

And the frequency is different. Stock investors might make 20-50 trades per year. Active crypto traders can make hundreds — each one a taxable event needing separate Form 8949 reporting.

4. Income events that stocks don't have

Stocks generate income through dividends (reported on 1099-DIV) and capital gains (reported on 1099-B). Two types of income, two forms, straightforward.

Crypto has several additional income events that stocks don't:

Each of these creates an income event at fair market value when received — and then a separate capital gains event when you sell. Stocks have nothing comparable. A dividend is income; selling the stock is capital gains. Two events. Crypto can have three, four, or five events on the same coins.

For more detail on how these income events work, our staking tax guide covers the income + capital gains double-event in depth.

5. Holding period calculation differs

For stocks, the holding period starts the day after purchase (trade date +1) and ends on the sale date. Buy on March 1, sell on March 2 of the next year → long-term.

For crypto, the IRS hasn't specified whether the trade date or settlement date applies — and with crypto, there's often no "settlement" in the traditional sense. The conservative approach: use the blockchain transaction date (when the crypto was received in your wallet) as the acquisition date, and the disposal transaction date as the sale date.

With stocks, the broker confirms settlement. With crypto, the blockchain timestamp is your evidence. This matters because if you're audited, the IRS will ask for proof of acquisition date — and for crypto, that proof is a blockchain transaction ID, not a broker confirmation.

One more wrinkle: if you received crypto as a gift, the holding period is the original giver's acquisition date — not the date you received the gift. This is the carryover holding period rule, and it catches people off guard. Our gift tax guide covers this in detail.

6. Loss treatment and deductibility

Both stocks and crypto allow you to use capital losses to offset capital gains. If losses exceed gains, you can deduct up to $3,000 per year against ordinary income, with the rest carrying forward.

But there's a practical difference: stock losses are easy to claim because your broker reports them on 1099-B. Crypto losses require you to have your own records — and if your cost basis is missing, you can't claim the loss at all.

Also, stock losses are subject to wash sale rules. If you sell a stock at a loss and rebuy within 30 days, the loss is disallowed. Crypto has no such restriction (as of 2026), making loss harvesting significantly more flexible.

7. Form 1099 and reporting differences

Stocks: Form 1099-B from your broker includes proceeds, cost basis, holding period, and wash sale adjustments. You copy it onto Form 8949 and Schedule D. Clean.

Crypto: Form 1099-DA from your exchange includes proceeds, but cost basis is often missing for assets acquired externally. You need to supplement with your own records. And if you use multiple exchanges or wallets, you need to reconcile across all of them — no single form covers your entire crypto activity.

The reporting burden is higher for crypto because:

• You may receive multiple 1099-DAs from different exchanges
• DeFi and self-custody wallet activity isn't reported on any 1099
• Income events (staking, mining, airdrops) may not be on any 1099
• You need to reconcile exchange-reported proceeds with your own basis records

If the 1099-DA shows $50,000 in proceeds but your actual cost basis was $45,000, you need to file Form 8949 with adjustment code "B" (basis not reported on 1099) and provide your own basis. If you just copy the 1099 numbers, you'll overpay by treating $50,000 as gain instead of $5,000.

Summary: crypto vs stock tax at a glance

Practical advice for stock investors filing crypto taxes

If you're coming from the stock world, here's what to do differently for crypto:

Track your own cost basis. Don't wait for a 1099 to tell you what you paid. Export transaction histories from every exchange and wallet you've used. The 1099-DA will likely have gaps; your records fill them.

Use the wash sale loophole while it exists. If you have crypto losses, you can harvest them and immediately rebuy — no 30-day waiting period. This is a legitimate tax strategy that stock investors can't use. But document your strategy in case the rules change.

Report income events separately. Staking, mining, and airdrops aren't on your 1099-DA. You need to report them as income on Schedule 1 or Schedule C. The 1099 only covers sales.

Reconcile multiple 1099s. If you used three exchanges, you'll get three 1099-DAs. Make sure you're not double-counting transfers between exchanges as both income and sales. Our reporting guide walks through the reconciliation process.

Use crypto-specific tax software. Stock tax software (TurboTax, etc.) can handle crypto, but dedicated crypto tax tools (Koinly, CoinTracker) parse wallet history and DeFi transactions that general tax software misses. If you've done anything beyond simple exchange buys and sells, use crypto-specific tools.

The takeaway

Same capital gains rates, different rules underneath. The crypto wash sale advantage is real money. The cost basis tracking burden is real work. Knowing which rules apply to which asset class is the difference between a clean filing and an audit.

Two things to do this week: First, export your full transaction history from every crypto exchange and wallet you've used in 2026 — you'll need it for basis tracking. Second, run your crypto gains through our free calculator to see what you owe. If you also have stock losses, the calculator can show how much crypto gain those stock losses can offset.
