I am using QB Simple Start and KeyPay for payroll. If I stop using KeyPay(I am the only employee of the company) will QB still allow me to be STP compliant?

Hi TollHouseService, 

Thank you for reaching out on this and welcome to our community. 

The STP component is within the payroll function powered by KeyPay in QuickBooks Online. Do you mind if I ask why you are looking to stop using KeyPay and what payroll solution you'd be looking to replace KeyPay, please?

Thank you.
