Expanding into the United States market introduces complex sales tax obligations for international businesses. US sales tax is managed at the state level, meaning compliance requirements vary depending on where your customers are located.

Many international companies are unaware of nexus rules, which can result in unexpected tax liabilities and compliance issues.

IST supports international businesses entering or operating in the US market by providing full sales tax compliance assistance. We help determine where nexus has been established, handle registrations, and manage ongoing filing obligations across multiple states.

We also review historical activity to identify any prior exposure and assist with back filing requirements or available amnesty programs.

• State registration and compliance setup

Understanding your tax obligations is the first step. Software alone cannot solve compliance complexity without proper legal and operational structure in place.
