Quiet desk work for crypto tax estimates on your PC

Bring your exchange exports and wallet notes. We turn them into a clear tax estimate worksheet and a transaction summary you can keep for filing season.

A desk session, not a spreadsheet lecture

Most visitors arrive with partial CSV files, screenshots, and a tax year deadline. We sit with those records on a desktop screen and produce numbers you can actually use.

Flagship: Desktop Tax Estimate Session

A scheduled 90-minute review of your disposals, cost basis gaps, and KRW conversions for the tax year you name.

Session details

Transaction Summary Planning

Ordered ledger of buys, sells, transfers, and fees from your PC exports.

Filing Season Review

A second pass on your finished worksheet before you sit with your tax preparer.

Cost Basis Reconstruction

Rebuild missing purchase history when exchange records stop mid-year.

What clients bring back to the office

“I had three exchange CSVs and no shared date format. The estimate session left me with one desktop worksheet and a short list of lines still needing bank statements.”
— Hyejin K., Yeouido

“The summary planning took longer than I hoped because my transfer notes were incomplete, but the final ledger finally matched what I remembered from 2024.”
— Minsoo P., Mapo
