U.S. & KOREA DUAL CPA
By integrating elite experience from Big 4 CPA firms and Fortune 100 companies with professional licenses in both the U.S. and South Korea, we deliver an unparalleled, holistic perspective.
Korean Parent Companies and Their U.S. Subsidiaries
For a Korean company with a U.S. subsidiary, we handle both sides of the relationship: the subsidiary’s U.S. books and tax filings, and the reporting package the parent needs for its Korean IFRS (K-IFRS) consolidation.
- U.S. bookkeeping and tax — monthly books and federal and state tax filings for the U.S. subsidiary.
- Parent reporting package — account mapping, US GAAP to K-IFRS adjustments, and KRW translation schedules, prepared in the parent’s own format.
- Close adjustments and intercompany reconciliation — monthly and quarterly close entries, matched against the parent’s intercompany balances.
- Headquarters and group auditor support — answering requests from the parent’s finance team and the group auditor.
Based in Los Angeles, we work with clients across the United States: remotely, at our Los Angeles office, or on site, including trips to your headquarters in Korea.
