When filling out the state tax information for payroll taxes, what account number are they are asking for? Ive tried my EIN number and it won't accept it.

QuickBooks Online (QBO) will ask for your state account number when you file for your state taxes, christopher. Let me help you sort this out. 

When you create a business, your state assigns and issues a unique tax identifier so your company is registered legally. In order to process your employee's pay using our program, we'll need your state account number to do this task successfully. You can find this listed on your business registration or incorporation documents. 

On the other hand, an EIN or Employee Identification Number is a federal tax code issued and assigned by the Internal Revenue Service (IRS). 

If you are unsure about your state code, it's best to request it from your state agency or the IRS directly to ensure you receive the legitimate identifier.

To enter your employee's paycheck information, you can read this article for guidance: Add pay history to QuickBooks Online Payroll.

I'm more than willing to assist you if you have further questions about your account number in QBO. I'm just one post away.
