Have you ever opened your mailbox to find a letter from the IRS, your heart sinking as you wonder what you might’ve done wrong? For cryptocurrency investors, this scenario is becoming all too common. The IRS is cracking down, sending out waves of warning letters—6173, 6174, and CP2000—to crypto holders across the U.S. These notices aren’t just polite reminders; they’re a signal that the taxman is watching your digital wallet closely. But what do these letters really mean, and should you be worried? Let’s dive into the murky waters of crypto taxes, unpack these letters, and figure out how to stay on the right side of the IRS without losing your cool.
Why the IRS Is Targeting Crypto Investors
The crypto market has exploded, with Bitcoin soaring to $107,617 and Ethereum hovering around $2,441 as of June 2025. This meteoric rise has caught the IRS’s attention. Virtual currency isn’t just a buzzword anymore—it’s a taxable asset, and the IRS is determined to ensure every transaction is reported. From my perspective, it’s no surprise; the agency has been playing catch-up with crypto’s rapid growth, and now they’re armed with better tools to track your trades.
The introduction of Form 1099-DA, a new crypto-specific tax form set to roll out this year, has supercharged the IRS’s ability to monitor transactions. Exchanges like those you might use to trade Bitcoin or Solana are now required to report user activity directly to the IRS. This means your crypto moves—whether buying, selling, or staking—are no longer flying under the radar. The surge in warning letters is a direct result of this increased scrutiny, and it’s shaking up the crypto community.
The IRS is sending a clear message: crypto isn’t a tax-free playground anymore.

The Three Types of IRS Crypto Letters
Not all IRS letters are created equal. The agency uses three main types—6173, 6174, and CP2000—to communicate with crypto investors. Each has a different tone, purpose, and level of urgency. Understanding which one you’ve received is the first step to handling it properly. Let’s break them down.
Letter 6174: The Gentle Nudge
If you’ve received a Letter 6174, consider it a friendly tap on the shoulder. This “soft notice” is informational, meaning you don’t need to take immediate action. It’s the IRS saying, “Hey, we know you’ve been dabbling in crypto—make sure you’re reporting it.” While it’s tempting to toss this letter in the shredder, don’t. It’s a subtle hint that your transactions are on their radar, possibly because you’re using a U.S.-based exchange or someone reported your activity via a Form 1099-MISC.
In my experience, this letter is a wake-up call. It’s a chance to double-check your past tax filings for accuracy. Did you report that Bitcoin sale from 2020? What about those staking rewards? Ignoring this letter might not bite you now, but it could lead to more serious notices down the line.
Letter 6173: The Warning Shot
Now we’re getting serious. Letter 6173 is a step up in intensity, and it’s not one to ignore. This letter explicitly states that the IRS has information about your crypto accounts and suspects you may have underreported your income. It’s like getting a note from your boss saying, “We need to talk about your performance.” The IRS might have gotten their data from exchanges or third-party sources, and they’re not just guessing—they’ve got specifics.
This letter often points to discrepancies, like unreported staking rewards or missing capital gains from crypto-to-crypto trades. You’ll have a deadline—usually 30 days—to respond or face a potential audit. My advice? Don’t procrastinate. A tax professional can help you review your records and respond before things escalate.
CP2000: The Bill Comes Due
The CP2000 notice is the one that makes your stomach drop. Issued by the IRS’s Automated Underreporter Unit, this letter comes with a specific dollar amount the IRS believes you owe. It’s not a suggestion—it’s a demand for payment or a dispute. The good news? Sometimes these notices are wrong, generated by algorithms that misinterpret data. The bad news? You’ve got to act fast to sort it out.
If the amount seems off, don’t just pay it to make it go away. I’ve seen cases where taxpayers were overcharged because the IRS didn’t account for certain deductions. A tax attorney can help you challenge the notice if needed, but you’ll need to gather your transaction records to make your case.
Why Are These Letters Showing Up Now?
The timing of this IRS crackdown isn’t random. The crypto market’s growth, combined with new regulations, has given the IRS the tools to go after unreported income. Here’s what’s driving the surge:
- Form 1099-DA: This new form requires exchanges to report your crypto transactions, giving the IRS unprecedented visibility.
- Data from Exchanges: Platforms like Kraken and Coinbase are sharing user data with the IRS, making it easier to spot discrepancies.
- Third-Party Reporting: If someone paid you in crypto via a 1099-MISC or 1099-B, the IRS knows about it.
- Advanced Tracking: The IRS’s tech has improved, allowing them to cross-reference your filings with exchange data.
Perhaps the most interesting aspect is how the IRS is leveraging technology to close the gap. They’re not just relying on your honesty anymore—they’re actively hunting for unreported crypto income. It’s a bit unsettling, but it’s the new reality for investors.
How to Respond to an IRS Crypto Letter
Getting a letter from the IRS can feel like a punch to the gut, but panicking won’t help. Here’s a step-by-step guide to handling these notices like a pro:
- Read the Letter Carefully: Identify whether it’s a 6174, 6173, or CP2000. Each requires a different response.
- Gather Your Records: Pull all your crypto transaction data—trades, staking rewards, mining income, everything.
- Check Your Tax Filings: Compare your records to what you reported. Look for errors or omissions.
- Consult a Professional: A crypto-savvy tax attorney or accountant can help you respond accurately and avoid penalties.
- Meet Deadlines: Most letters give you 30 days to respond. Don’t miss this window, or you could face an audit.
One thing I’ve learned from talking to crypto investors is that staying proactive is key. If you’ve been sloppy with your tax reporting, now’s the time to clean it up. The IRS isn’t messing around, and the consequences of ignoring them can be steep—think penalties, interest, or even audits.
Common Crypto Tax Mistakes to Avoid
Why do so many crypto investors get these letters in the first place? It’s not always intentional tax evasion. Here are some common pitfalls that could land you in hot water:
| Mistake | Why It’s a Problem | How to Fix It |
| Not Reporting Staking Rewards | Considered taxable income | Track all staking income and report it annually |
| Ignoring Crypto-to-Crypto Trades | Triggers capital gains tax | Record every trade and calculate gains/losses |
| Missing Mining Income | Taxable at fair market value | Document mining rewards on receipt |
| Incorrect Cost Basis | Leads to wrong tax calculations | Use FIFO or specific ID for accuracy |
These mistakes are easy to make, especially if you’re new to crypto or juggling multiple wallets. I’ve seen folks assume that crypto-to-crypto trades are tax-free, only to get slapped with a CP2000 later. A little diligence goes a long way here.
The Bigger Picture: Crypto and the Future of Taxes
The IRS’s focus on crypto isn’t just about collecting taxes—it’s about setting a precedent. As digital currencies become mainstream, the government wants to ensure they’re not a loophole for tax evasion. But there’s a twist: the incoming Trump administration has floated ideas about abolishing the IRS entirely, replacing it with a consumption-based tax system. Could this mean relief for crypto investors? Maybe, but don’t hold your breath.
Abolishing the IRS sounds radical, but it’s a long shot that could reshape how we think about crypto taxes.

For now, the IRS is doubling down, and Form 1099-DA is just the beginning. Exchanges will report more data, and the IRS’s algorithms will get smarter. This means crypto investors need to stay ahead of the curve, documenting every transaction and seeking professional advice when needed.
Practical Tips for Staying Compliant
Navigating crypto taxes doesn’t have to be a nightmare. Here are some actionable tips to keep the IRS off your back:
- Use Tax Software: Tools designed for crypto can track transactions and generate tax reports.
- Keep Detailed Records: Log every buy, sell, trade, and reward. Spreadsheets or blockchain explorers can help.
- Understand Your Obligations: Know what’s taxable—sales, trades, staking, and even airdrops.
- Work with Experts: A crypto tax professional can save you time and money in the long run.
I can’t stress enough how much easier life is when you stay organized. A friend of mine ignored his crypto taxes for years, only to spend months untangling records after a 6173 letter. Don’t be that guy.
IRS warning letters are a wake-up call for crypto investors. Whether it’s a gentle nudge like the 6174 or a serious demand like the CP2000, these notices mean the IRS is watching. By understanding what each letter means, avoiding common tax mistakes, and staying proactive, you can navigate this new era of crypto compliance with confidence. The taxman may be knocking, but with the right approach, you’ll be ready to answer the door.
