Tax reports —
done for your heirs, done for their accountant.
Automatic stepped-up basis at claim execution. Per-heir, per-asset cost-basis tracking. Jurisdiction-aware forms. Export CSV, PDF, or structured JSON for your tax software.
The biggest tax trap in crypto inheritance is inheriting an asset at its original cost basis — paying capital-gains on your parent's 10,000x appreciation. Nearly every major jurisdiction has a "stepped-up basis" rule that resets basis to fair-market value at inheritance.
HeirVault computes the step-up automatically, pulls oracle pricing at the exact block of claim execution, and produces the forms your heirs hand to their accountant. No spreadsheets, no guessing, no audit risk.

Questions
Frequently asked
What is stepped-up basis and why does it matter?
When someone inherits an asset, most tax jurisdictions reset the asset's cost basis to its fair market value at the moment of inheritance. This "step up" can wipe out decades of accumulated capital gains — your heirs pay tax only on gains from the inheritance date forward, not your lifetime gains. Crypto is no exception.
Which jurisdictions are supported?
US (IRS Form 8949 + Schedule D), EU (per-country via common framework, tested in Germany, France, Spain, Netherlands), UK (HMRC capital gains), UAE (no personal income tax but CRS reporting), Singapore (stepped-up basis, no estate tax). Canada and Australia in beta.
How is fair market value determined?
The report pulls on-chain oracle pricing at the exact block of claim execution — CoinGecko for ERC-20s, Chainlink for blue-chip pairs, DEX TWAP as fallback for long-tail. Same methodology the IRS accepts for crypto-asset appraisal.
Can my accountant use the report directly?
Yes. Exports include CSV for TurboTax/H&R Block/CoinTracker, PDF narrative for a human reviewer, and structured JSON for the tax-software API path. Per-lot detail for every asset, per-heir share breakdown.
Does the vault owner owe tax during life?
No — supplying to AAVE, moving between chains, or holding doesn't trigger taxable events under US rules. Your heirs' basis steps up at inheritance. If you sell from the vault during life, normal capital-gains rules apply.
Your heirs won't thank you for the crypto. They'll thank you for the tax report.
