TaxKstones (Huwon Tax Corporation) is a Korean tax firm centered on international tax. For companies expanding abroad and foreign companies entering Korea, we address tax issues at their source — the transaction itself — and build a foundation that holds on both sides of the border.
Not a single filing, but a lasting relationship. We build trust that runs deep.
We look past the figures to their source: the transaction and its structure. Get the source right, and the outcome holds.
Solid ground for a growing business to stand on — tax work laid carefully, one stone at a time.
Our certified tax accountants work together as peers, not in a hierarchy. Each advisor takes direct, end-to-end responsibility for their clients, and we share expertise across specialties to find better answers.
Work is never simply handed down the line, so you always speak directly with the advisor who knows your matter best.
Every cross-border transaction is governed by at least two tax systems and a tax treaty at once. Decisions made from one side alone come back as double taxation or unexpected assessments. We start by understanding the structure and the flow of funds, then review Korean tax law, the other jurisdiction's rules and the applicable treaty together.
The moment you invest in or set up a foreign entity, or earn foreign-source income, Korean reporting obligations and tax issues begin.
We help foreign corporations and foreign-invested companies operate with confidence under Korean tax law, from establishment through ongoing compliance.
Dedicated support for the cross-border transactions of outbound Korean companies and foreign-invested companies, including transfer pricing and treaty application.
Tax adjustments and corporate income tax returns based on your financial statements, with a thorough review of available credits and incentives.
Preliminary and final VAT returns, with advance review of taxability, input tax credits and transaction-specific issues.
Accurate apportionment and filing across business locations, along with refund opportunities through claims for correction.
Tax opinions for business decisions, from transaction structuring to impact reviews before key decisions.
Accurate books lead to accurate returns. We manage ongoing bookkeeping, withholding tax and statutory filings.
