Finance and Tax for the U.S. Subsidiary of a Chinese Company: One Team, Readable in Beijing, Defensible with the IRS

For a U.S. C corporation owned by a Chinese company, a normal operating year looks like this. Monthly: bookkeeping and close, payroll runs and tax deposits, sales-tax returns in some states. Quarterly: Form 941 federal payroll returns, state unemployment returns, corporate estimated tax. Annually: Form 1120 federal income tax, income or franchise tax in the home state and every nexus state, Form 5472 for each foreign related party, W-2/W-3 and 1099s, Forms 1042/1042-S on payments to the parent, the state annual report, and a transfer-pricing file that can withstand review.

Most problems do not come from not knowing a filing exists. They come from the basis of the books: the chart of accounts, cost centers and currency translation headquarters wants do not match the U.S. tax basis, so the two sides cannot be reconciled at year end; intercompany balances have no agreement or pricing support; expenses the parent paid on the subsidiary's behalf never hit the books and drop off Form 5472. We set up the ledger from month one so that headquarters can consolidate and the U.S. return can be prepared from the same data — no year-end rebuild.

If the subsidiary employs executives assigned from China, individual-level questions stack on top: substantial-presence day counts, which country taxes the salary, the totalization agreement and FICA, and how housing and travel paid by the U.S. company are treated. We work these through with your immigration counsel and China HR.

• Dual-basis bookkeeping and monthly close: the QuickBooks ledger mapped to headquarters' chart of accounts, with currency translation and intercompany balances tracked separately; bilingual management reports and consolidation workpapers within ten business days of month end.
• Payroll and employer compliance: payroll setup and processing, Forms 941/940, state unemployment, W-2s and 1099s; salary sourcing and FICA treatment for assigned executives.
• Sales tax and multistate compliance: nexus review, state registrations, recurring returns; new obligations assessed before entering a new state.
• Federal and state income tax: Form 1120 and state returns, multistate apportionment, quarterly estimates; Form 5472 for each related party and §6038A records.
• Cross-border payments and treaty positions: characterization and withholding on dividends, interest, royalties or service fees paid to the parent (U.S.–China treaty rates), Forms 1042/1042-S, W-8BEN-E collection and Form 8833 disclosures.
• Transfer-pricing documentation: pricing support and contemporaneous documentation for intercompany services, goods and licenses, consistent with what Form 5472 discloses.
• Fractional tax leadership: the annual tax calendar, notice handling and coordination with counsel, banks and the parent's tax team — acting as the subsidiary's tax lead when needed.
