Register before you collect

You generally need to be registered with a state before you start collecting its sales tax. Collecting without registering is not the shortcut it seems, so registration comes first.

Gather your details

Registration asks for basic business information and details about your activity in the state. Having your identifiers, contact details, and start date ready makes the process straightforward rather than stop and start.

Note your filing obligations

Registering creates ongoing responsibilities, chiefly filing returns on a schedule the state assigns. Record the frequency and deadlines the moment you register, so you never miss the first one.

Switch on collection

Once registered, update your checkout to collect the correct rate for that state. This is where an accurate, address level rate matters, so you charge customers the right amount from day one.

Key takeaways

Register with a state before collecting its tax
Have your business details ready to speed registration
Record your filing frequency and deadlines at once
Switch on accurate collection immediately after
