Unveiling the US Sales Tax System and Its Impact A Comprehensive Guide You Can't Afford to Miss

In today’s increasingly integrated global economy, cross-border trade and e-commerce are booming. As a result, more and more businesses and individuals are paying attention to tax systems around the world-especially Value Added Tax VAT. However, unlike many countries that have adopted a VAT system, the United States does not have a unified national VAT. Instead, it operates a complex and decentralized sales tax system that varies significantly from state to state, with major implications for businesses, consumers, and international trade.

Why Doesn’t the US Have a National VAT?

The U.S. is one of the few major developed countries that does not implement a VAT system. Instead, it relies on a sales tax model managed at the state and local level. This structure stems from the country’s federal system, where individual states enjoy a high degree of autonomy, including the power to set their own tax policies.

In recent years, the rapid growth of e-commerce-driven by platforms like Amazon and eBay-has led to a surge in interstate transactions. This has placed significant pressure on the traditionally fragmented sales tax system. A major turning point came in 2018 when the U.S. Supreme Court ruled in South Dakota v. Wayfair that states can require out-of-state sellers to collect and remit sales tax, even if they have no physical presence in the state. This decision marked a fundamental shift in U.S. sales tax policy and accelerated the trend of states imposing tax obligations on online marketplaces.

Sales Tax Variations Across States

Although the U.S. does not have a unified VAT, its sales tax system shares key similarities-particularly in that the end consumer ultimately bears the cost. However, unlike VAT, which is collected at each stage of production based on value added, U.S. sales tax is typically collected only once, at the point of sale, by the retailer, who then forwards it to the state.

As of the end of 2025, five U.S. states do not impose a general sales tax New Hampshire, Oregon, Montana, Alaska, and Delaware. These states generally rely on other revenue sources such as income taxes or property taxes. In contrast, states like California have combined state and local tax rates exceeding 10%. Other states, including New York, Illinois, and Tennessee, also have relatively high rates, with additional local taxes varying significantly from city to city.

Impact on Businesses and Consumers

For cross-border e-commerce businesses, especially those based in China and other overseas markets, understanding and complying with the sales tax rules in each U.S. state is essential. Sellers using fulfillment services like Amazon FBA Fulfillment by Amazon must be particularly mindful of where their inventory is stored, as this can trigger tax obligations in certain states.

According to a 2025 industry report, more than 60% of small and medium-sized cross-border sellers said they face significant challenges in complying with U.S. sales tax reporting and filing requirements. Key difficulties include inconsistent state rules, varying filing frequencies, and complex exemption rules.

Sales tax also influences consumer behavior. For example, e-commerce platforms that operate warehouses in low-tax or no-tax states often attract more orders. This explains why companies like Amazon actively build logistics centers in tax-friendly regions.

Future Trends Digitalization and Automation

In response to the growing complexity of tax compliance, more businesses are turning to automated tax solutions. Platforms such as Avalara, TaxJar, and Vertex help sellers calculate tax liabilities in real time, generate reports, and even file returns automatically. These tools not only improve efficiency but also significantly reduce tax-related risks.

At the same time, U.S. states are also investing in digital upgrades to their tax systems. In 2025, several states announced improvements to their online tax registration and filing systems, aiming to enhance data sharing and better manage the tax challenges brought by e-commerce growth.

Conclusion

While the U.S. does not have a traditional VAT system, its sales tax framework serves a similar economic function and carries significant consequences. For any business looking to succeed in the American market, understanding this system is critical-from ensuring legal compliance and managing costs to improving the customer experience.

Whether you're a small business just entering the U.S. market or a global company with an established presence, staying informed about the latest developments and operational procedures in each state’s sales tax system is a crucial step toward long-term success.
