Hi and welcome to Just Answer!
Are you an employer or you are an employee?
Did you ever applied for the tax ID?
What state do you live?
we have a federal EIN but not sure where to locate a state id number i need it to put on the w-2's
In most states - you may use the same ID
An IRS notice CP 575 was sent when when a Employer ID Number (FEIN) was issues.
What state do you locate?
New york so i can uses my federal tax id? i have a stae unemployemt number is XXXXX what i should use
You might have a state tax ID in NY for the collection of sales tax. Do not use unemployemt number on the W2.
we dont colect sales tax
In this case - just use your federal tax ID.
Additional Note - seems that you may use NY state ID which you are using to remit SUTA taxes in the place of the state ID on the W2 form - sorry for confusion.
But if you use the federal ID in both places - that will be accepted as well.
Sorry for confusion.
