Just last tax season, in April 2025, a new client, a young programmer we’ll call ‘DeFi Dave’, came to me with an IRS notice for a $25,000 tax bill he didn’t know he owed. His mistake wasn’t a bad trade; it was a simple swap of his Ethereum for a liquidity pool token on Uniswap.
More than ever, you need to fully understand how taxes will impact your crypto trades!
My unique take? The biggest threat to a new crypto investor isn’t market volatility; it’s tax illiteracy. They don’t realize that in the eyes of how the IRS views your crypto, every swap is a sale. This isn’t just a guide to the rules; it’s a playbook for survival, fortified with insights from my 25 years in the trenches and expert commentary from CPA Minnie Lau and EA Crystal Stranger.
According to a mid yer 2025 report by the crypto analytics firm Chainalysis, less than 1% of self-custody wallets have ever interacted with a tax reporting tool. Is your wallet in the 99% that’s flying blind?
Key Takeaways Ahead
The Four Dispositions: Exactly What Triggers a Crypto Tax?
Let me be blunt & to the point. The IRS doesn’t see ‘cryptocurrency.’ It sees ‘property.’ And any time you dispose of property, you have a taxable event. To simplify this, I created a framework called ‘The MRM Four Dispositions.’
If you do one of these four things, you have a taxable event:
1. Sell it for Cash:
The most obvious. You sell 1 Bitcoin for $70,000. That’s a disposition. You’ll likely receive a Form 1099-B from an exchange like Coinbase for this.
2. Swap it for Another Crypto:
This is the #1 mistake. Example: You swap 1 ETH (which you bought for $2,000) for 30,000 Cardano (ADA) at a moment when that 1 ETH is worth $3,500.
You have just realized a $1,500 capital gain on your ETH. Your cost basis for your new ADA is now $3,500.
3. Spend it on Goods or Services:
I had a client in 2024 who used his Coinbase card to buy groceries for a year.
Example: You buy a $5 coffee with BTC. If the fraction of BTC you used was worth only $4 when you acquired it, you have just realized a $1 capital gain that must be tracked and reported.
4. Earn it as Income:
This isn’t a capital gain initially; it’s income.
- Staking Rewards: You receive 0.1 ETH in staking rewards when the price of ETH is $3,500. You must report $350 of ordinary income. Your cost basis for that 0.1 ETH is now $350.
- Airdrops & Learn-to-Earn: You receive an airdrop of 500 ARB tokens when the price is $1.10. You have $550 of ordinary income to report.
This concept is critical because of the new IRS Section 6045 regulations, which will require brokers to issue Form 1099-DA (Digital Assets).
My prediction: By 2027, the IRS will use AI to automatically match 1099-DA forms with self-reported returns, making audits for non-compliance trivial. Are your transactions prepared for that level of scrutiny?
Short-Term vs. Long-Term Gains: A Tale of Two Tax Bills
Once you have a taxable event, the calendar is your most important tool. Your holding period, down to the day, determines your tax fate.
- Short-Term Capital Gain:
Profit from crypto held for 365 days or less. Taxed at your high ordinary income rate (up to 37%). - Long-Term Capital Gain:
Profit from crypto held for 366 days or more. Taxed at much lower rates of 0%, 15%, or 20%.
Michael Ryan Money’s Micro-Example:
Meet Tina. She’s in the 24% income tax bracket and has a $10,000 profit on some Solana.
- If she sells on day 365, her tax bill is $2,400.
- If she waits one more day and sells on day 366, she qualifies for the 15% long-term rate. Her tax bill is $1,500.
Tina saved $900 just by waiting 24 hours. This is the simplest and most powerful tax strategy there is. For a full breakdown, see my guide on Short & Long-Term Capital Gains Tax Rates.
Calculating Your Gains: The Cost Basis Battle
Your taxable gain is your sale price minus your cost basis. The cost basis isn’t just the purchase price; it’s the price plus all associated fees: exchange trading fees, network gas fees, and fiat on-ramp fees.
A Client Story: The Peril of a “Black Hole” Cost Basis
‘DeFi Dave,’ the programmer I mentioned earlier. He was providing liquidity to a Uniswap V3 pool. His tax software couldn’t read the transaction hashes from his self-custody wallet, so it defaulted his cost basis on the swapped assets to $0.
This created a phantom profit of $75,000. We had to use a blockchain explorer for two days to manually trace his activity and prove his real cost basis.
The lesson: Crypto tax software is not a magic bullet; it’s a ‘garbage in, garbage out’ system. The software is the calculator, not the accountant.

Beyond the Obvious: Choosing Your Cost Basis Method
This is an advanced strategy competitors miss. You can often choose your accounting method to strategically minimize taxes.
Scenario: You bought 1 ETH on three separate occasions: 1 ETH @ $1,000, 1 ETH @ $4,000, and 1 ETH @ $2,000. You decide to sell 1 ETH today when the price is $3,000.
- Using Highest-In, First-Out (HIFO):
You sell the ETH you bought for $4,000. The result is a$1,000 capital loss ($3,000 sale – $4,000 basis). This is ideal for tax-loss harvesting. - Using First-In, First-Out (FIFO):
You sell the ETH you bought for $1,000. Resulting in a $2,000 Capital gain ($3,000 sale – $1,000 basis).
Your choice of accounting method for the exact same sale created a $3,000 difference in your taxable income.
Gray Areas: Staking, Airdrops, and NFT Taxes
- NFTs: Generally treated as property, subject to capital gains.
A key detail: if you paid 0.1 ETH in gas fees to mint an NFT and that ETH was worth $300 at the time, your cost basis for that NFT is $300. - Staking & Airdrops: The value of tokens you receive is taxed as ordinary income the moment you receive them.
Reporting to the IRS: The Essential Forms
You must report every transaction on Form 8949, which then gets summarized on Schedule D of your tax return. Even a net loss must be reported to be claimed.
Michael’s Pro Playbook: 4 Smart Strategies for 2025
- Time Your Sales: Use your calendar. A single day can be the difference between a 15% and a 37% tax rate.
- Strategic Tax-Loss Harvesting: Use the HIFO method to generate specific losses that can offset your gains.
- The Crypto Wash Sale “Loophole”: A 2025-2026 Warning
Currently, the wash sale rule does not apply to crypto because it’s property, not a security. This means you can sell BTC for a $5,000 loss today and buy it back tomorrow, successfully harvesting the loss while maintaining your position. This is a huge advantage over the stock market. However, there are active legislative proposals to close this loophole.
My contrarian take: Actively use this strategy while it’s clearly legal, but build a plan for a future where it may no longer exist. - Donate Appreciated Crypto: Donating directly to a qualified charity can allow you to deduct the full value and avoid the capital gains tax.
The Risks of Ignoring Your Taxes
In March 2025, I worked with a client who received an IRS Letter 6173. This wasn’t a standard notice; it demanded an explanation for his unreported crypto, citing the infamous ‘John Doe Summons’ the IRS has used against exchanges like Kraken to obtain user data.
Here’s the hard truth from Crystal Stranger, EA: “If you don’t pay…the IRS will pursue criminal prosecution…and can prevent passport renewal for tax debt over $54,000.” The age of hiding is over. The only question left is, will you file correctly now, or will you pay an accountant like me double to fix it later under the threat of an audit?
Frequently Asked Questions (FAQ)
Do I pay taxes if I just buy and hold crypto?
No. Buying and holding is not a taxable event.
Is swapping ETH for SOL taxable?
Yes. You are technically selling ETH and buying SOL, triggering a gain or loss on the ETH.
Can I write off crypto losses?
Yes. You can use capital losses to offset capital gains. If you have more losses than gains, you can deduct up to $3,000 of those losses against your regular income per year.
What’s the best cost basis method for crypto?
It depends on your goal. HIFO is often best for maximizing tax-loss harvesting in a down market. FIFO can be better for realizing long-term gains in a rising market. Consult a professional and keep detailed records.
