State Tax ID Number Guide
A state tax ID is separate from your federal EIN. States issue their own tax registration numbers for state income tax, sales tax, and payroll. Each state has its own system.

Frequently Asked Questions
Is a state tax ID the same as an EIN?
No. An EIN is federal (from IRS). A state tax ID is from your state revenue department. Different numbers, different agencies.
Do I need both state and federal tax IDs?
If you have state tax obligations (employees, sales tax), yes. The federal EIN does not cover state requirements.
How do I get a state tax ID?
Register with your state's revenue or tax department. Each state has its own application process and forms.
Is a state tax ID free?
Most states issue tax IDs for free. Some charge small registration fees ($10-50).
Which states have no state tax ID?
States with no income tax (WY, NV, TX, FL, SD, WA, AK, NH, TN) may still require employer IDs for payroll purposes.
