Does Proconnect Tax online have the ability to do payroll taxes or is that an additional service you need to purchase using quickbooks or another intuit software?

If I read this correctly, there is no charge for Proconnect tax online, you get charge for a per return basis, correct?

is there an additional charge for the efile or is that included in the per return fee?

I am in the middle of writing a business plan for a small tax preparation business and trying to get an idea of cost.

Thanks!
