Before you can pay employees, make sure you've registered for the applicable work and live in state. This can sometimes take several weeks—the sooner you start the process, the sooner you'll have the tax account information required to pay them.

Note, CertiPay Online can put your account in an applied for status. This may cause additional monthly fees as some states do not accept returns/tax liability deposits for accounts that are in an applied for status.
