Sales Tax Exposure in New York

New 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.

Why New York Creates High Sales Tax Exposure

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.

Key reasons New York exposure is commonly underestimated include:

New York audits frequently focus on businesses that assumed they were covered or below thresholds. Exposure often exists even when tax was never collected.

What Triggers Sales Tax Exposure in New York

Sales tax exposure in New York is created when a business has sufficient connection to the state and sells taxable goods or services without proper compliance. Exposure does not require registration or collection to exist.

Economic Nexus in New York

Economic nexus is triggered when a remote business exceeds New York’s economic activity thresholds through sales into the state.

Important context for exposure:

  • Nexus can be triggered by transaction volume, revenue, or both
  • Thresholds apply to taxable sales, not total revenue
  • Marketplace sales may count toward nexus even if tax is collected by the platform

Economic nexus establishes an obligation to evaluate exposure even if no action has been taken yet. For a deeper explanation of how nexus works across jurisdictions, see

Physical Presence Still Creates Exposure

Physical presence continues to create exposure in New York regardless of revenue levels.

  • Inventory stored in third party warehouses or fulfillment centers
  • Contractors or agents operating in the state
  • Temporary presence such as trade shows or short term projects

Even limited or indirect presence can create exposure that goes unnoticed for years.

Marketplace Sales Tax Exposure in New York
