Why is this important?
OnPay works with government entities on your behalf, reporting new hires to state labor departments, calculating tax rates, paying taxes and insurance contributions, and filing financial reports. To do this effectively, you will need to authorize us to act on your behalf with tax offices for each state where your company has a tax obligation.
For example, if you operate in both Kentucky and Tennessee, you must grant us access for both states.
Each tax office has its own authorization process, and may require different actions for you to take. We've detailed every step for each office below. We may need you to provide your tax registration information, or return a completed power of attorney (POA) form. In these cases, you'll see a button to "Submit a request". This request form is used to securely transmit your business information.
