Why is this important?
To maintain compliance with state payroll tax regulations, you must provide the following information before you can use OnPay to run payroll:
- State Employer Identification Number and state/local tax IDs
- Tax rates - State tax offices set these rates based on the type, age, and size of your business
- TPA and power of attorney - Most tax offices require this before we can submit quarterly wage reports and deposits on your behalf
This information must be provided and maintained by you in order for OnPay to accurately file and deposit tax payments for your company. OnPay is not responsible for any penalties or interest that incur due to missing or incorrect company tax information.
