Crypto Tax Season 2026: What US Holders Need to Know

A weekly roundup of the latest developments in crypto taxation, enforcement, and compliance.

Introduction

The IRS has shifted from gentle warnings to full enforcement mode. After years of voluntary compliance pushes and warning letters, the taxman is now playing hardball—and the 2025 tax year marks the first time the new reporting regime actually bites.

If you hold, trade, stake, or mine cryptocurrency, the April 15, 2026 filing deadline is approaching fast. This year, however, the stakes are higher than ever. Form 1099-DA is rolling out, brokers must report your transactions directly to the IRS, and blockchain analytics firms are feeding the agency data on transactions you may have assumed were private.

Here's what's changed, what's stayed the same, and what you need to do before the deadline.

1. The IRS's Stance on Crypto: Property, Not Currency

Let's start with the foundation. Since IRS Notice 2014-21, the agency has treated cryptocurrency as property for federal tax purposes—not currency. That single classification drives everything else.

Taxable events: - Selling crypto for fiat currency (USD, EUR, etc.) - Swapping one crypto for another (BTC to ETH, for example) - Spending crypto to buy goods or services - Receiving crypto as payment for work, services, or mining - Earning staking rewards or airdrops

Non-taxable events: - Buying crypto with fiat and holding it - Transferring crypto between your own wallets or exchanges - Gifting crypto (up to the annual exclusion limit of $19,000 per recipient in 2025)

Every taxable event triggers a capital gain or loss based on the difference between your cost basis and the fair market value at the time of the transaction.

Key Takeaway: If you sold, swapped, or spent any crypto in 2025, you have a taxable event. Period. There's no threshold—even a $50 trade counts.

2. New Reporting Requirements: Form 1099-DA and Broker Rules

This is the big one for the 2025 tax year.

The Infrastructure Investment and Jobs Act (2021) expanded the definition of "broker" to include crypto exchanges and payment processors. Starting in 2025, they're required to file Form 1099-DA with the IRS, reporting gross proceeds and—where available—cost basis for their customers' digital asset transactions.

What this means for you:

• Your exchange (Coinbase, Kraken, Binance.US, etc.) will send a copy of your 1099-DA to the IRS.
• The IRS will compare those forms against what you report on your tax return.
• Discrepancies trigger automated notices and, potentially, audits.

The catch: The 1099-DA may not include your cost basis if you transferred assets between exchanges or wallets. That means the IRS could see a large gross proceeds figure with no basis—and assume you owe tax on the full amount. It's on you to reconcile this with accurate records.

Key Takeaway: Don't just rely on your 1099-DA. If you moved crypto between platforms in 2025, you need to track your cost basis yourself or use tax software that can aggregate your transaction history.

3. Capital Gains and Losses: What You Owe

Short-term vs. Long-term Gains

The holding period determines your tax rate:

For 2025, the long-term capital gains brackets are: - 0%: Single filers up to $48,350; married filing jointly up to $96,700 - 15%: Single filers up to $533,400; married filing jointly up to $600,000+ - 20%: Above those thresholds

High-income earners also face the 3.8% Net Investment Income Tax (NIIT) on top.

Calculating Cost Basis

The IRS defaults to FIFO (First-In, First-Out) unless you specifically identify which lots you're selling. If you bought Bitcoin at $20,000 in 2022 and again at $50,000 in 2025, then sold some in December 2025, FIFO assumes you sold the 2022 coins first—potentially triggering a larger gain.

You can elect specific identification (lot-by-lot) if you can document which units you sold. Most exchanges now support this, but you need to make the election before filing.

Tax-Loss Harvesting

Realized losses offset realized gains dollar-for-dollar. If your losses exceed your gains, you can deduct up to $3,000 against ordinary income per year, with any excess carried forward indefinitely.

Important: The wash sale rule—which disallows losses if you repurchase the same security within 30 days—does not currently apply to crypto. That means you can sell at a loss and buy back the same asset immediately while still claiming the deduction. However, proposed legislation could change this for 2026, so don't assume it's permanent.

Key Takeaway: If you have unrealized losses in your portfolio, consider realizing them before April 15 to offset gains or generate a deduction. Just be aware the rules could tighten next year.

4. Staking, Airdrops, and Mining: Ordinary Income

These aren't capital gains—they're ordinary income at the time you receive them.

Staking Rewards

Final Treasury regulations issued in 2024 clarified that staking rewards are taxable as ordinary income at the fair market value when you gain "dominion and control" over them. That means the moment the rewards hit your wallet, you owe tax—even if you haven't sold.

Airdrops

New tokens received via airdrop are generally taxable as ordinary income at their fair market value upon receipt. The IRS has clarified this in Notice 2014-21 and subsequent guidance. If you later sell those tokens, you'll have a capital gain or loss based on the difference between the value at receipt and the sale price.

Mining

Mining income is treated as self-employment income. You owe income tax plus the 15.3% self-employment tax (Social Security and Medicare) on the fair market value of coins at the time you mine them. You may also be able to deduct mining-related expenses (equipment, electricity, internet) as business costs.

Key Takeaway: For staking, airdrops, and mining, the taxable event happens at receipt—not when you sell. Plan for the tax hit before you spend the proceeds.

5. Foreign Accounts and FBAR Reporting

Holding crypto on a foreign exchange can trigger additional reporting requirements.

FBAR (FinCEN Form 114): If the aggregate value of your foreign financial accounts—including crypto held on foreign exchanges like Binance, Bybit, or Kraken's international arm—exceeds $10,000 at any point during the calendar year, you must file. The deadline is June 30, 2026, with no extension available.

FATCA (Form 8938): If you have specified foreign financial assets exceeding certain thresholds ($50,000 on the last day of the year, or $100,000 at any point, for single filers), you may also need to file Form 8938 with your tax return.

Penalties for non-compliance are severe: Willful FBAR violations can trigger penalties of the greater of $100,000 or 50% of the account balance per violation. Criminal prosecution is possible in egregious cases.

Key Takeaway: If you trade on any non-US exchange, track your aggregate holdings carefully. The $10,000 FBAR threshold is lower than most people think.

6. IRS Enforcement and Penalties

The IRS isn't just asking nicely anymore.

Blockchain analytics: The agency has contracts with firms like Chainalysis to trace transactions on public blockchains. They can follow funds from exchanges to wallets and identify taxpayers who underreport.

Warning letters: In 2024, the IRS issued over 10,000 warning letters to taxpayers with unreported crypto transactions. That number is expected to grow significantly in 2025 and 2026.

What happens if you don't report: - Accuracy-related penalty: 20% of the underpaid tax - Fraud penalty: 75% of the underpaid tax if the IRS proves intentional misconduct - Criminal prosecution: For willful tax evasion, you face up to 5 years in prison and fines up to $250,000

The IRS Criminal Investigation Division reported collecting over $1 billion from crypto-related enforcement in 2023 alone. That number has been climbing.

Key Takeaway: The IRS has the data and the tools to find unreported crypto income. The cost of non-compliance far exceeds the cost of doing it right.

7. Key Deadlines for 2026

Mark these dates now:

Note: The extension to October extends your filing deadline, not your payment deadline. If you owe tax, interest accrues from April 15 regardless.

8. Common Misconceptions Debunked

"Crypto-to-crypto trades are like-kind exchanges." False. The Tax Cuts and Jobs Act of 2017 eliminated like-kind exchange treatment for personal property. Every crypto-to-crypto trade is a taxable event.

"I don't need to report if I didn't get a 1099." False. The IRS requires you to report all income, whether or not you receive a form. The 1099-DA is for the IRS's benefit—not your excuse to skip reporting.

"I can deduct unlimited crypto losses." No. Losses offset gains first, then up to $3,000 against ordinary income per year. The rest carries forward.

"Buying crypto is a taxable event." No. Buying and holding is not taxable. Selling, swapping, spending, or earning is.

"Crypto is anonymous." False. Every transaction is recorded on a public ledger. The IRS uses blockchain analytics to trace transactions to individuals.

FAQ

Do I need to report crypto if I only bought and held it? No. Buying and holding is not a taxable event. You only report when you sell, swap, spend, or earn crypto. However, you must still answer the virtual currency question on Form 1040.

How are crypto-to-crypto trades taxed? As capital gains or losses. The fair market value of the asset you receive is compared to the cost basis of what you gave up.

What is the deadline for filing my 2025 crypto taxes? April 15, 2026. You can file for an extension until October 15, 2026, but payment is still due April 15.

Can I deduct crypto losses? Yes, up to $3,000 against ordinary income per year after offsetting gains. Excess losses carry forward to future years.

What happens if I don't report my crypto transactions? You risk accuracy penalties (20%), fraud penalties (75%), and potential criminal prosecution for tax evasion. The IRS is actively auditing and investigating unreported crypto.

Are NFTs taxed differently than other crypto? No. The IRS treats NFTs as property, same as other digital assets. Selling an NFT triggers capital gains tax based on your cost basis.

Do I owe taxes on staking rewards? Yes. Staking rewards are ordinary income at fair market value when you gain dominion and control.

How do I calculate cost basis if I bought on multiple exchanges? Use FIFO by default, or elect specific identification if you can track which lots you're selling. Crypto tax software can aggregate across exchanges.

What's the difference between short-term and long-term capital gains? Short-term gains (held under 1 year) are taxed at ordinary income rates. Long-term gains (held over 1 year) are taxed at 0%, 15%, or 20% depending on your income.

Do I need to report crypto held on a foreign exchange? Yes. If the aggregate value exceeds $10,000 at any point, you must file FBAR. Additional FATCA reporting may apply.

Conclusion and Actionable Tips

The 2025 tax year is a turning point. With Form 1099-DA in play and the IRS armed with blockchain analytics, the era of "I didn't know I had to report" is over.

Here's your action plan:

1. Gather your transaction history from every exchange and wallet. Don't assume your exchange has it all—especially if you transferred between platforms.
2. Use crypto tax software (CoinTracker, Koinly, TokenTax, etc.) to calculate gains, losses, and income. The average cost basis error rate on manual filings is estimated at 15%.
3. Reconcile your records against your 1099-DA. If the IRS has a higher gross proceeds figure than your reported gains, you'll get a notice.
4. Consider tax-loss harvesting before April 15 if you have unrealized losses.
5. Consult a tax professional if you have staking income, foreign accounts, or complex transactions. This is not the year to DIY if your situation is complicated.

The deadline is April 15, 2026. Start now—the longer you wait, the more expensive the mistakes become.
