Well I need an appointment or can I do a walk-in off the street

Yes. An appointment is required for service in our office. You can make a reservation on our website at hillstax.org.

Depending on what services u need

if you go as a walk in they would have everyone with an appointment go before you even if you're first in line or get there early. if they are packed they will set an appointment for you at the front desk. this is from my experience.
