Missing records or a broken cost basis on your crypto? We can reconstruct even the messiest histories.

// who we are

Crypto losses might seems like a tax headache. To us, they're an opportunity.

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. A defunct exchange, DeFi with no statements, or years of early trading nobody thought would matter. People arrive convinced their situation is hopeless. It almost never is. The blockchain doesn't forget, if you know where to look. We built CountDeFi to rebuild exactly this, and hand you a report that holds up. Hunting down 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.
