The purpose of the Multi-City Portal project is to create an online portal where what is currently a ministerial tax collection and business licensing function can be collectively administered, and to facilitate “one-stop” tax payment or business license applications for businesses operating in multiple participating cities. Businesses will be able to register online one time for all participating cities; file information online once each payment period (including payment information); and then, business and occupation taxes due to each participating city will be calculated and paid automatically. Similarly, business licenses can be secured in multiple participating cities by a single online application.
