The Role of Local Tax Jurisdictions in Sales Tax Collection

When it comes to sales tax compliance, most businesses focus on state-level obligations—but that’s only part of the picture. In many U.S. states, local tax jurisdictions—such as cities, counties, and special districts—play a major role in determining how much sales tax you collect, file, and remit.

For businesses selling in multiple areas or online, ignoring these local jurisdictions can lead to serious compliance issues, financial penalties, and increased audit risk. Understanding and managing your obligations at both the state and local levels is key to maintaining tax compliance and protecting your bottom line.

What Are Local Tax Jurisdictions?

Local tax jurisdictions are governmental entities below the state level that are authorized to impose additional sales taxes on top of the state sales tax rate. These may include:

• Counties

• Cities or municipalities

• Transit authorities

• Tourism or stadium districts

• Public improvement districts

• Other special taxing zones

Each of these entities may charge different tax rates, often leading to thousands of unique combinations across the country. That means one ZIP code may have a total sales tax rate of 6%, while the next ZIP code over could have a combined rate of 9% due to local additions.

Why Local Sales Tax Is So Complex

There are more than 11,000 local tax jurisdictions in the U.S.—each with its own rules and filing requirements. For businesses selling across multiple areas, this creates challenges in:

• Correctly calculating the total tax due based on customer location

• Identifying where nexus has been established, even unintentionally

• Keeping up with tax rate changes and local tax holidays

• Filing separate returns for each state or local agency

• Responding to audits from multiple authorities

To make things even more complicated, some states follow destination-based sourcing (taxing where the buyer is located), while others use origin-based sourcing (taxing where the seller is based). These sourcing rules impact how local sales tax is applied.

The Real Business Risk

If you’re not correctly collecting and remitting sales tax for each applicable jurisdiction, you could be:

• Under-collecting taxes, making your business liable for the shortfall

• Overcharging customers, which damages trust and may result in refund obligations

• Missing filing deadlines, incurring interest and penalties

• Triggering audits, which take time and resources and could expose more liabilities

Businesses that operate online or ship nationwide are especially vulnerable if they don’t have systems in place to manage these local tax complexities.

The Role of Local Tax Jurisdictions in Sales Tax Collection

For businesses operating in multiple locations, the role of local tax jurisdictions in sales tax collection is a critical factor in compliance. Local jurisdictions can impose their own tax rates and filing requirements, adding complexity to the collection and remittance process. Understanding these local nuances helps ensure accurate tax calculations and reduces the risk of costly errors.
