C Corporation Tax Services


Tax compliance and advisory for U.S. corporations and foreign-owned U.S. subsidiaries.


C corporation taxation can involve much more than filing an annual return. Schmid CPA helps businesses manage federal and state tax compliance while connecting the tax return to the company’s underlying accounting, transactions, and business operations.

Federal & State Corporate Tax Returns

  • Preparation and filing of Form 1120 and applicable state corporate income and franchise tax returns.

Tax Planning & Estimated Taxes

  • Year-round support with estimated tax payments, taxable income considerations, deductions, and planning opportunities.

Book-to-Tax Review

  • Review of financial statements and accounting records to identify tax adjustments and help ensure the return is consistent with the company’s books.

Foreign-Owned U.S. Corporations

  • Specialized support for U.S. corporations owned by foreign companies or individuals, including additional international reporting requirements.

Form 5472 & Related-Party Reporting

  • Identification and reporting of applicable transactions between U.S. corporations and foreign owners or related parties.

Ongoing CPA Support

  • Tax questions do not always happen at year-end. We provide ongoing support for business changes, transactions, accounting questions, and tax planning throughout the year.

A corporate tax return is only as reliable as the accounting behind it.


Because Schmid CPA provides both tax and accounting services, we can look beyond the tax forms to understand how transactions were recorded, identify potential issues, and help businesses maintain cleaner financial records throughout the year.



For companies that need additional support, our services can extend from annual tax preparation to ongoing accounting and financial reporting.

A Operating a U.S. subsidiary creates additional accounting and tax considerations.


Schmid CPA works with international businesses navigating the U.S. environment, including:


  • Foreign parent company ownership
  • Intercompany transactions and balances
  • Management fees and related-party activity
  • Form 5472 reporting
  • U.S. federal and state corporate tax filings
  • Coordination between U.S. accounting and overseas finance teams
  • Ongoing U.S. accounting and compliance support


Our international perspective helps bridge the gap between the U.S. business and its overseas owners, accountants, and finance teams.

Some businesses need an annual corporate tax return. Others need a CPA who understands their accounting throughout the year.


Schmid CPA can support both.
