How Oleg Listunov Assisted a Startup Owner in Successfully Navigating U.S. Tax Compliance and Avoiding Hefty Penalties — A Practical Case Study
Oleg Listunov, a seasoned legal expert specializing in U.S. business law and taxation, was approached by a startup entrepreneur facing critical challenges related to complex tax compliance issues in the United States in 2025. The entrepreneur had rapidly expanded his technology company but lacked the necessary expertise to properly manage tax obligations, which exposed the business to significant financial risks, including potential IRS penalties exceeding $500,000.
The client's primary difficulty was navigating the intricate U.S. tax codes applicable to foreign-owned startups, especially regarding quarterly filings, payroll taxes, and multinational tax treaties. Previous attempts to self-manage taxes had resulted in errors on tax forms, missed deadlines, and unclear financial documentation, all of which escalated the risk of audits and fines.
Key Client Issues:
— Misclassification of income streams and expenses;
— Failure to file timely quarterly tax reports;
— Lack of compliance with IRS reporting requirements;
— Insufficient understanding of applicable tax treaties;
— Risk of audit with potential penalties and interest charges.
