When you inherit crypto, the IRS expects a 'step-up in basis' valuation at the date of death — but reconstructing cost basis from scattered wallets and exchanges can cost executors $5,000–$20,000. We tested the top crypto tax tools on manual basis adjustment, professional service availability, and integration breadth to find the best options for heirs and estate executors.
If you've ever tried to piece together a deceased relative's crypto portfolio from a dozen wallets, three exchanges, and a sticky note with a seed phrase, you already know: crypto inheritance is a tax nightmare.
The IRS applies a step-up in basis rule to inherited assets — meaning the cost basis resets to the fair market value on the date of death.1 That's great in theory. In practice, it means your executor needs to reconstruct the entire purchase history, figure out what each asset was worth on a specific date, and produce a clean audit trail for the estate tax filing. Without proper records, expect to pay a specialist $5,000 to $20,000 just to reconstruct the cost basis.2
The right crypto tax software can save your heirs that headache — and that bill. Here's what we recommend.
Not every crypto tax calculator handles estate scenarios well. We focused on three dimensions that matter most for executors and heirs:
koinly is the industry standard for automated gain/loss calculations, and it's especially strong for multi-country support — essential when an estate spans jurisdictions.3 It automatically tags DeFi, derivatives, margin trades, NFTs, lending, and income transactions, which means less manual cleanup for executors who aren't familiar with the deceased's trading activity.3
Where it shines for inheritance: Koinly lets you manually adjust the cost basis on individual transactions, so you can set date-of-death valuations. It also generates IRS-compliant tax reports (Form 8949) that executors can hand directly to a CPA.
awaken tax offers a full-service option that's a lifeline for executors who don't know the difference between a hot wallet and a cold one. Their team handles the data gathering, cost-basis reconstruction, and tax filing — you basically hand them the login details and they do the rest.
For estates with complex holdings across multiple chains, this "done for you" model removes the single biggest risk: an executor making a costly error on the estate tax return. The trade-off is price — full-service plans cost more — but compared to a $5,000–$20,000 specialist bill, it's often a bargain.
cryptotaxcalculator excels at custom tagging and DeFi support, which matters when the deceased was active in yield farming, liquidity pools, or airdrop farming. You can create custom tags for inherited assets, making it easy to separate pre-death and post-death transactions in reports.
Its manual cost-basis adjustment is straightforward: select the transaction, enter the date-of-death value, and the tool recalculates gains accordingly. The reporting is granular enough for high-net-worth estates that need to show their work to the IRS.
taxbit is built for enterprise-grade accuracy and compliance. If the estate involves significant assets — think seven figures or more — TaxBit's institutional-level reporting is worth the premium. It's used by some of the largest crypto exchanges and financial institutions for their own reporting, which tells you something about its audit-readiness.
The platform supports manual basis adjustments and generates GAAP-compliant reports that satisfy even the most demanding estate attorneys. The catch: it's overkill (and overpriced) for smaller portfolios.

Crypto tax software typically charges based on transaction count — expect to pay $100–$500 for a standard plan, and $1,000+ for full-service or enterprise tiers. Compare that to the $5,000–$20,000 a specialist would charge to reconstruct records from scratch, and the software pays for itself many times over.2
