Unsure where you owe sales or use tax or dealing with legacy compliance pain?
Check Your ExposureNew York is one of the most complex and aggressively enforced sales tax jurisdictions in the United States. Sales tax exposure in New York is rarely caused by a single mistake. It usually builds quietly over time as a business grows, expands into new channels, or misclassifies what it sells. Many businesses believe sales tax only becomes an issue once they register or start collecting. In reality, exposure often exists long before any action is taken. Understanding how New York defines exposure is the first step toward reducing risk and avoiding unexpected liabilities.

New York combines broad tax authority, layered local jurisdictions, and strict enforcement practices. This creates exposure even for businesses that do not operate physically in the state.
