Frequently Asked Questions
Common questions about state tax IDs

A Tax Registration, also called a sales tax permit or employer withholding number, is required if you plan to hire employees or collect sales tax in your state. It's different from your EIN (federal tax ID).

Often yes. Your EIN is for federal taxes, while the State Tax ID is for state-level employment taxes or sales tax collection. If you're hiring employees or selling taxable products/services, you typically need both.

Processing time varies by state, typically 1-3 weeks. Some states issue numbers immediately online, while others require manual review. We'll handle the entire process and notify you once approved.

You'll need your business's EIN, legal name, address, and details about whether you'll sell products or hire employees. We'll guide you through collecting all necessary information.
