Check Your Exposure

TaxMap Tools

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

Businesses typically use TaxMap Tools to answer three critical questions: where they have sales tax nexus, how much unpaid sales or use tax exposure may exist, and whether products or services are taxable in specific jurisdictions.

How the Tools Work Together

TaxMap Tools are designed to be used in sequence, with each tool building on the output of the previous step. The process typically begins by identifying where a business has sales or use tax nexus. Once nexus is known, potential liability can be quantified. After exposure is estimated, product and service taxability can be validated. If exposure exists, remediation options can be planned before engaging with tax authorities or advisors.
