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 Wisconsin and Minnesota, you must complete and return a power of attorney for each state.
