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 grant us Power of Attorney for each state where your company has a tax obligation. For example, if you operate in both Mississippi and Alabama, you must complete and return a power of attorney for both states.

We've got you covered with downloadable, pre-populated POA forms, with any actions you'll need to take. All you have to do is fill out your information, sign the forms, and return them to us. We'll take it from there!
