// who we are
Messy crypto data is a tax nightmare. We love the challenge.
The IRS Is Taxing Crypto Gains You Never Made
When your cost basis is missing, Form 1099-DA reports your sale proceeds with no basis attached, and the IRS can treat your basis as zero. That makes your whole sale look like gain. We rebuild the real numbers so you're taxed on your actual profit, not your proceeds.
Your Records Are Scattered or Gone
Dead exchanges, DeFi with no statements, transfers you never tracked, trades from 2015 you barely remember. You can't piece it back together, and most accountants can't read the chain. We're equipped to find and reconstruct the hardest cases.
Broken Crypto Portfolios Cost A Fortune to Fix
Yes, reconstruction has a reputation for long hours and painful bills. But we don't charge by the hour. Our plans scale with your volume and complexity, and every plan includes the reconstruction, the reconciliation, and the finished report.
// who we are
"Roughly half the clients who come to us have a data gap of some kind. People arrive convinced their situation is hopeless. We built CountDeFi to deal with exactly this. The blockchain doesn't forget, if you know where to look. Hunting down crypto data is not a challenge for us, it's our speciality."

A crypto loss is only worth something if it's claimed correctly
We've been rebuilding complex crypto and on-chain histories since 2017, for clients with data gaps stretching back to 2013. The hard part is rarely the tax rule. It's the evidence. A missing cost basis is the expensive problem. Under Form 1099-DA, the selling platform reports yourproceeds to the IRS with no record of what you paid, so the system assumes your cost was zero andbills you on the full amount. One client sold $85,000 of Ethereum he had bought for 72,000. His real gain was $13,000, but with his 2019 purchase records gone he faced tax on the whole$ 85,000. Rebuilding that basis is the difference, and it is exactly what we do.
Missing crypto transactions is a reality in 2026, not an edge case. Exchanges shut down, DeFi issues no statements, transfers go untracked, and early-years trading was never recorded. We gather every fragment you have, trace the rest through blockchain explorers , reconcile it across wallets and chains, and settle a defensible cost basis with the methodology documented behind it.
The result is a Form 8949 that tells the accurate story and stands up if the IRS asks. Getting a broken history rebuilt doesn't have to cost a fortune. At CountDeFi we do not bill by the hour. Our pricing scales with transaction volume and complexity, and all plans include software fees,transaction reconciliation, and a complete tax report.

Our crypto portfolio reconstruction services
Cost Basis Reconstruction
Most inflated tax bills trace back to missing basis. We rebuild it from wallet, exchange, and on-chain data, documented and audit-proof
Dead Exchange Recovery
FTX, Celsius, Voyager, QuadrigaCX. When the platform is gone, we
rebuild the record from trustee data, fragments, and the chain.
DeFi & On-Chain Reconstruction
Non-custodial activity issues no statements. We interpret swaps, liquidity, staking, and bridging from raw contract data.
1099-DA Basis Repair
We reconcile the proceeds a broker reported against your actual activity, so azero-basis mismatch doesn't become a tax bill.
Portfolio History Rebuild
We reconstruct a complete transaction history across every platform and wallet you've used, from your first buy to your last sale.
Wallet & Transfer Reconciliation
Untracked transfers break the basis chain. We trace crypto as it moves between exchanges and wallets so cost basis follows the asset all the way.
Blockchain Forensic Tracing
We read the chain directly through explorers, reconstructing activity from nothing more than a wallet address when that's all that's left.
Cross-Border & Multi-Year Reconstruction
For histories spanning several years and jurisdictions, we rebuild the full picture, including the US, South Africa, Australia, Canada, the UK, Germany, andSpain.
// EXPERT SKILLS
Why crypto investors with incomplete crypto tax records hire CountDeFi
Nobody enjoys handing the IRS a return they can't fully back up. People come to us for a few plain reasons. They want the inflated tax bills gone, because being taxed on proceeds they never profited from is money straight out of pocket. They want their records rebuilt properly, so the report holds up if anyone asks and doesn't resurface as a problem years later. They want to stay off the audit radar, since a return full of gaps and zero-basis sales is exactly what draws attention. And they want all of it without a bill that rivals the tax it saves. That is what we deliver. The CountDeFi team rebuilds the history from the evidence, settles a basis you can defend, reconciles it against what the IRS already sees, and prices the work so it costs less than it saves. You hand over the mess, and you get back a clean, audit-ready report.
// TAILORED PRECISION
Why tax software can't rebuild crypto statements
Tax software is a great starting point, but it can only work with the data you feed it. Software is not the problem. Koinly, for example, is a genuinely good engine, which is exactly why we use it and why we are proud to be Koinly's #1 Global Accounting Partner. But no accounting tool can recover a history from a dead exchange, read raw contract interactions from a self-custody wallet, or decide a defensible cost basis when the records aren't there. That reconstruction is the whole job, and it is the part that moves your final bill. So we handle it ourselves: we gather the fragments, trace the chain, and rebuild the numbers. If you already have a Koinly portfolio, we can work directly from it.

CountDefi did a great job at reconciliation and I recommended them for their dedication to detail. The IRS schedule forms they provided in their reports were pivotal to filing my taxes smoothly.

Given the complex nature of cryptocurrency transactions, calculating taxes is extremely difficult. This has been a major problem for me in previous years and CountDeFI is a life changing solution for me! The entire process is extremely surprisingly smooth.

Frequently asked questions
What does crypto cost basis reconstruction actually involve?
Can you reconstruct crypto records if an exchange shut down, like FTX or Celsius?
Crypto cost basis reconstruction rebuilds the acquisition history behind assets whose original purchase price, date or source is missing. CountDeFi traces transactions across exchanges, wallets and blockchains, matches transfers between accounts, identifies acquisitions and disposals, and rebuilds the cost basis needed for tax reporting. We also document the records and methodology used, so you have an accounting trail behind the final figures rather than a collection of estimated values.
Yes. Closed or bankrupt exchanges are a common reason crypto transaction histories break. Where the original exchange export is unavailable, CountDeFi works from the evidence that remains, including wallet addresses, blockchain transactions, trustee or bankruptcy records, emails, bank records and previous tax files. We use those records to rebuild the missing parts of the history and reconnect them with activity that continued elsewhere.
I have no records from my early crypto trading years. Can you still rebuild my cost basis?
Can you fix missing cost basis that is making my crypto gains look too high?
Often, yes. We regularly reconstruct historical crypto accounting where the original CSVs, exchange accounts or tax software records no longer exist. Wallet addresses, blockchain records, old emails, screenshots, bank statements, previous returns and later transactions can all help establish what happened. The older the history, the more investigative work may be required. We document where each reconstructed figure came from and identify any gaps that cannot be supported by the available evidence rather than quietly filling them with assumptions.
Yes, where the acquisition history can be established from the available records. Missing cost basis can make a disposal appear far more profitable than it really was because the calculation does not include what you originally paid for the asset. CountDeFi traces the asset backwards through wallets, exchanges and earlier transactions to recover the acquisition history and rebuild the basis. This is particularly useful where a tax report, Form 1099-DA or existing crypto tax software account shows proceeds but has incomplete basis information.
Can you reconstruct DeFi, bridges and self-custody wallet activity?
Can you repair an existing Koinly or crypto tax software portfolio instead of starting again?
Yes. CountDeFi specialises in reconstruction where the missing history sits on-chain rather than inside an exchange account. We can investigate swaps, liquidity pool transactions, staking, lending, borrowing, wrapping, bridging and transfers across self-custody wallets and multiple chains. These histories often break because tax software sees individual blockchain transactions without understanding how they relate to one another. A bridge can look like an unexplained withdrawal and deposit, an LP position can leave missing assets, and an internal wallet transfer can be mistaken for a disposal. Reconstruction puts those transactions back into context.
Yes. A broken crypto tax software account does not automatically need to be rebuilt from zero. CountDeFi can review existing imports, identify missing or duplicate transactions, investigate unmatched transfers and missing cost basis, and correct the underlying accounting where the existing data is usable. This can be useful if you have spent years maintaining a Koinly or other crypto tax software portfolio but no longer trust the final gain, loss or cost basis figures. We fix the transaction history first, then produce the tax reporting from the reconciled data. Learn more about our Software Review support.
How much does crypto cost basis reconstruction usually cost?
How much does CountDeFi charge for crypto reconstruction and cost basis work?
The cost depends on how much history needs to be rebuilt and how difficult the missing records are to recover. Across the industry, reconstruction may be billed by the hour, quoted as a separate forensic accounting project, or priced according to transaction volume and complexity. A missing exchange CSV covering 200 straightforward trades is a different job from rebuilding 8 years of activity across wallets, failed exchanges, DeFi protocols and several blockchains. When comparing reconstruction services, check whether the quote includes the investigation itself, transaction reconciliation, software, cost basis work and final tax reports, or whether those are separate charges.
CountDeFi's crypto tax accounting plans start at $695 for up to 500 transactions. Standard is $1,695 for up to 3,000 transactions, Premium is $2,995 for up to 5,000, Expert is $4,495 for up to 10,000, and Degen is $5,995 for up to 15,000 transactions. The appropriate plan depends on both the number of transactions and the amount of reconstruction your portfolio needs. CountDeFi's standard plans are not billed by the hour. Missing-data analysis, transaction reconciliation, software and the completed crypto tax report are included, so the work does not end with us simply finding your missing basis. We rebuild the accounting and carry those corrected records through to the final tax reporting. See CountDeFi pricing and plans.
