Let me be clear upfront: I'm not anti-software. We actually use Koinly as part of our process at CountDefi. It's a great tool.
But a tool is not a solution.
The clients who find their way to me have almost always tried crypto tax software already. They've connected APIs, uploaded CSVs, clicked "generate report," and then stared at numbers that don't make sense. Transactions are missing. Cost basis is wrong. DeFi activity is miscategorized. The software says they owe $80,000 in taxes on gains they never actually realized.
That's when they call me.
After years of cleaning up these situations, I've developed a clear view of what crypto tax software can and can't do. And why, for anyone with meaningful complexity, human expertise isn't optional.
Crypto Tax Software Limitations
Let's start with a major con: Crypto tax software is only as good as the data you feed it. To put it bluntly, "Garbage In, Garbage Out."
That sounds obvious, but most people don't realize how bad their data actually is until they try to use it. Exchange APIs have limitations. CSVs are incomplete. Wallet connections miss transactions. Transfers between your own accounts get misclassified as sales.
One of my clients, Ben, had been doing his own crypto taxes for years using various software tools. He had a high number of trades across multiple platforms. Here's how he described it:
"I used to do my crypto taxes on my own and tried a bunch of different plug-in software to keep track of everything. Because I have a high number of trades, it took a ridiculous amount of time and effort."
Ben isn't unusual. He's technically sophisticated. He understood the tools. But he was spending days wrestling with data that still came out wrong.
The problem isn't user error. The problem is that software can't fix incomplete or inconsistent source data. It can only process what it receives.
I've identified several critical gaps that even the best crypto tax software consistently fails to address.
1. Crypto Tax Software and Missing Data
APIs have limits. Crypto.com's API only provides transactions from the last two years. Sub-account history is limited to six months. And that's just Crypto.com's tax story. Most platforms have data limitations.
If your trading history goes back further, or if you've used exchanges that have since shut down, restricted US access, or changed their data export formats, software has nothing to work with. Even the best crypto tax software can't chase down missing data.
Gary came to us with exactly this problem:
"They (CountDefi) squared away my thousands of transactions across multiple wallets, exchanges, and blockchains. Some of my info was incomplete because some exchanges went under or no longer allowed access to me from the US, but they were able to work with what I had."
Another client, Andrew, described his situation as "a mess of data across exchanges, including incomplete info from BlockFi." BlockFi, of course, went bankrupt in 2022. Getting complete records from a defunct exchange isn't something software can handle. It requires research, outreach, and sometimes reconstructing transaction history from blockchain data.
"The team at CountDeFi was sharp, professional, and easy to work with. They helped clean everything up and walked me through the options clearly. It's obvious they know the space well."
— Andrew Waters, verified client
Software can't make phone calls. It can't submit data requests to bankruptcy trustees. It can't cross-reference on-chain activity against partial exchange records to fill gaps. Humans can.
2. Software Can't Handle the Unexpected
Some situations are so unusual that no algorithm could anticipate them.
Josephine came to us after losing most of her trading information in an exchange hack. She then received a payout from the subsequent lawsuit and liquidation process. Try plugging that into TurboTax.
"They really held my hand while they pieced through what was a very confusing and unique situation after I lost most of my trading information in an exchange hack after a subsequent payout from the lawsuit/liquidation process. Wish I could give them more than 5 stars!"
— Josephine Martin, verified client
Exchange hacks. Lawsuit settlements. Liquidation payouts. Frozen accounts on offshore platforms. These aren't edge cases anymore. In crypto, the unexpected happens constantly. Software is built for predictable patterns. Real portfolios don't always follow them.
3. Software Misclassifies Complex Transactions
DeFi is where software really struggles.
When you provide liquidity to a pool, claim rewards, bridge assets across chains, wrap and unwrap tokens, or interact with lending protocols, the resulting transactions don't fit neatly into "buy" and "sell" categories. Software often misreads these entirely: treating liquidity provisions as sales, missing impermanent loss, or double-counting assets that were wrapped and unwrapped.
Richard had tried other tools before finding us:
"I found other crypto calculators lacking in complete blockchain analysis, but CountDeFi effectively traced my complex crypto journey and ultimately systematized order from disorder. Massive weight off my shoulders!"
— Richard Parker, verified client
The "order from disorder" Richard describes isn't something an algorithm produced. It's the result of a human analyst understanding blockchain mechanics and tax implications simultaneously.
4. Tax Software Doesn't Optimize
Tax optimization isn't just about accurate calculations. It's about applying the right methodology, selecting optimal inventory methods, identifying loss harvesting opportunities, and understanding holding periods across complex transaction chains.
Software applies whatever method you select (usually FIFO by default) uniformly. It doesn't analyze whether a different approach would produce a better outcome. It doesn't spot missing cost basis that's costing you money. Only experienced crypto tax accountants can do this.
Our client Brooks came to us specifically for this:
"They helped me clean-up and make whole all my transaction records as well as find missing cost-basis and potential for loss harvesting."
— Brooks Bailey, verified client
"Missing cost-basis" is a big deal. If software doesn't have your original purchase data, it may treat your entire sale proceeds as gain. That's not a rounding error. That's potentially thousands of dollars in unnecessary taxes.
5. Software Can't Handle Thousands of Transactions
Most crypto tax software works fine for casual investors with a few dozen transactions. But what happens when you have tens of thousands? Or hundreds of thousands?
We had a client this year with over 500,000 transactions that needed reconciliation. At that scale, software doesn't just slow down. It breaks. API timeouts. Memory limits. Processing errors. And even if you get it to run, the output requires extensive manual verification.
"Had over 500k+ transactions that I needed reconciled and CountDeFi got the job done with accuracy, thank you to the team."
There's no consumer software designed to handle that volume reliably. It requires infrastructure, process, and human oversight at every stage.
The Irony: We Use Software Too
Here's what might surprise people: at CountDefi, we use Koinly as part of our workflow. We rate it highly.
But we don't just plug in your data and hand you the output.
Koinly is one tool in a seven-step process that includes:
- Onboarding: Validating and gathering the right data sources
- Data Analysis: Normalizing, aggregating, and flagging gaps
- Reconciliation: Categorizing complex activity (DeFi, bridges, staking, NFTs)
- Context: Reaching out to you when transactions need clarification
- Tax Optimization: Analyzing inventory methods and harvesting opportunities
- Review: Control checks and multi-platform verification
- Finalization: Audit-ready report delivered for your CPA or tax authority
The software handles calculation at scale. The humans handle everything else.
That's the distinction most people miss. Software is a calculator. It's not an accountant, not a blockchain analyst, and not a tax strategist.
When Crypto Tax Software Is Enough (And When It Isn't)
I don't think everyone needs a service like CountDefi's. For some people, software genuinely is enough.
One of my clients, Jown, put it better than I could:
"If you're just a casual crypto participant with 25-50 trades on an exchange, CountDeFi's services may be overkill for you. But if it's been a couple years and you've bounced around between exchanges or wallets, dabbled in DeFi or NFTs, or... if you're like me and you've got 10,000 transactions over 5 years of history because you're a degen who's carelessly yolo'd head first into the trenches for half a decade, these guys (and gals) will help get you sorted!"
That's the honest answer.
Crypto Tax Software can work well if:
- You traded on one or two exchanges with no transfers between them
- You have a manageable number of transactions (under a few hundred)
- You didn't participate in DeFi, staking, or complex protocols
- Your exchange provides complete, accurate data exports
- You have the time and knowledge to verify the output
You've probably outgrown software if:
- You have activity across multiple exchanges, wallets, or chains
- You've used DeFi protocols, bridges, or liquidity pools
- You have years of transaction history, some from defunct or restricted exchanges
- Software produces results that don't match your actual holdings
- You've spent hours troubleshooting and still can't get a clean report
- Your transaction volume is in the thousands or higher
- You want a report that would hold up under IRS scrutiny
Most of my clients fall into the second category. They're not beginners who need hand-holding. They're sophisticated investors who've hit the limits of what DIY can accomplish.
What Audit-Ready Actually Means
Software can generate a Form 8949. That's not the same as being audit-ready.
Audit-ready means:
- Every crypto transaction is accurately categorized and documented
- Cost basis is verifiable and defensible
- Complex activity (DeFi, staking, NFTs) is properly treated
- The methodology is consistent and clearly explained
- Supporting records exist for every line item
- The report would withstand IRS examination
When CountDefi deliver a final report, it's designed to satisfy the strictest regulators, whether that's the IRS, HMRC, CRA, or ATO. If your accountant or a tax authority has questions, we have answers.
That's not a feature you can click in software.
Gary mentioned something important in his review: after we finished his report, he "was easily able to upload the results to TurboTax." That's the goal. We do the heavy lifting so the final step is simple.
The Real Cost of Getting It Wrong
Here's what I've learned from years of fixing crypto tax messes: the cost of doing it wrong almost always exceeds the cost of doing it right.
Underreporting because software missed transactions? That's back taxes plus accuracy penalties plus interest.
Overpaying because software miscalculated your cost basis? That's money you'll never get back.
Filing a return that can't withstand scrutiny? That's an audit, legal fees, and months of stress.
The clients who come to me after software failed them have already paid the "cheap" price once. Now they're paying again to fix it.
Why We Chose Koinly
People sometimes ask why we use Koinly specifically, given how many crypto tax tools exist.
The short answer: nothing else matches its coverage.
Koinly integrates directly with over 1,000 exchanges. That's not a marketing number. It matters practically. When a client comes to us with activity across Coinbase, Kraken, Crypto.com, KuCoin, Gate.io, and a dozen DeFi protocols, we need a tool that can ingest all of it without manual workarounds for every platform. Most competing tools tap out well before that.
The other factor is international support. We work with clients in the US, UK, Canada, Australia, and beyond. Each jurisdiction has different reporting requirements, different forms, different tax treatments. Koinly handles more countries than any other platform we've evaluated, which means we're not juggling multiple tools or building custom exports for each client's location.
To be clear: Koinly doesn't replace what we do. It handles the calculation layer once we've cleaned, reconciled, and categorized the data. But for that specific job, at the scale and geographic range we operate, it's the best tool available.
That's why we built our process around it.
The Bottom Line
Crypto tax software is a tool. A useful one, but still just a tool.
If your situation is simple, it might be all you need. But if you've got complexity (multiple platforms, DeFi activity, incomplete records, high volume, or years of accumulated history) software alone won't produce an accurate, optimized, audit-ready result.
At CountDefi, we built our process specifically for people who've outgrown DIY. We combine technical blockchain expertise with tax compliance knowledge, so you don't get stuck with software that can't handle your data or CPAs who hand the data work back to you.
If you've been wrestling with crypto tax software and the numbers still don't make sense, that's not a reflection of your skills. It's a sign you've hit the tool's limits.
The good news: there's a better way.
