US Sales Tax Economic Nexus Check

https://server.smithery.ai/founder-o2f8/us-sales-tax-nexus/mcp

● healthy

Which US states must a remote seller register in for sales tax? Give sales and order counts per state and get the states over their economic nexus threshold, the ones close to it, and each state's rule: threshold, measurement period, what sales count, marketplace sales, when to register, with the state revenue department source. All 45 sales tax states plus DC, including the 2024 to 2026 changes (Illinois, Kentucky, Utah, Indiana dropping the 200 order test). Free. Part of Nero Labs Rules.
