Get the full picture from a qualified 税理士

This is a free read-only estimate. A complete filing requires receipt-time JPY pricing for every event, regime election decisions, loss carry-forward tracking across years, and CARF reconciliation under the FY2026 reform.

Kairo Vault works with a network of crypto-specialist 税理士 who use our tooling end-to-end — including the audit-defense citation chain, NTA notice response generator, and pre-filing validator that catch rejection triggers before submission.

1

Read-only by design

Address is queried, not signed. We never see, request, or store private keys. No tx is created or broadcast.

2

CARF-aware methodology

Classification follows 国税庁 FAQ + the FY2026 reform structure used by KV's full tax engine (4,920+ LOC, ~75 tax services tests passing).

3

Estimate, not advice

Bracket math, current-price valuation. Filing requires receipt-time pricing + a licensed 税理士. KV does not provide tax advice.
