What if I entered the wrong "Date of first sales" when registering? I will not be ready to collect in each state by the date I entered.

Answer:   If you are not ready to collect or have not started making sales by the “Date of First Sales” you may cancel your registration and reapply when you are ready.

However, if you have a legal requirement to collect and remit tax to a state, ending your Streamlined registration does not remove that requirement.  You will need to contact those states directly to determine your licensing and reporting requirements.
