TaxMap Tools

Estimate sales tax exposure, use tax exposure, and sales tax nexus before filing, registering, or responding to an audit.

TaxMap tools are designed to identify sales tax and use tax exposure before filing, registering, or responding to audits. Each tool focuses on a specific step so businesses understand where obligations exist, how much liability may be present, and what to do next without committing to compliance prematurely.

Check Your Sales Tax Exposure

Estimate unpaid sales and use tax before filing or registration.

Businesses typically use TaxMap tools to answer three questions in order: where sales tax nexus exists, how much unpaid sales or use tax exposure may have accumulated, and whether products or services are taxable under state rules.

How the Tools Work Together

TaxMap tools are designed to be used in sequence. The process begins by identifying where sales or use tax nexus exists. Once nexus is identified, exposure can be estimated. After exposure is understood, taxability can be validated. If risk is present, remediation options can be evaluated before filing or engaging tax authorities.

Once you’ve completed your Nexus Risk Assessment, take the next steps to fix past exposure. If you’ve triggered nexus, it’s important to act quickly to stay compliant.
