What is a Sales Tax ID Number?

A Sales Tax ID Number (sometimes called a sales tax permit or seller’s tax account) allows a business to collect and remit sales tax to the state. It’s required in most states when selling taxable goods or services.

Do I need a Seller’s Permit and a Resale Certificate?

A Seller’s Permit authorizes you to collect sales tax on retail sales, while a Resale Certificate lets you buy goods tax-free for resale. Many businesses need both: the permit to sell, and the certificate to purchase inventory without paying sales tax.

What is a Resale Certificate used for?

A Resale Certificate is presented to suppliers so you can purchase items for resale without paying sales tax at checkout. You then charge sales tax when you sell to the end customer, where applicable.

What does State Business Registration include?

State Business Registration covers forming your legal entity or registering to do business with your state, plus state tax accounts where needed. It ensures your business is properly set up to operate and file taxes.

How fast can I get started?
