Summary
This article will explain how to add a new state.
Start in Maintenance\System Setup:

Make sure you are on the correct FEIN. If you only have one, you are in it by default. Then select the tab at the top titled, States/Workers Compensation.

Click the New button to add a new state.

Simply fill in the blanks. As depicted below, certain fields are mandatory to use the state.
Work State – The State you are adding.
Tax Code & SUI Code/s – These you get from your payroll provider as they will have to coincide with their system for tax purposes.
Current Rate Date – Will be the date the WC Rates will be effective. Your WC Carrier will be able to give you this date. If you have none, today's date should suffice.
Rate Type – The standard is default, however, in some instances, it is set to hourly. If in question, talk to your accountant.
Current Exp. Factor – Again your WC Carrier will give you this rate, also known as Ex-Mod.
Discount OT Pay for Calculations – This should come from your WC Carrier or accountant.

Once complete, click the Save button and you are done. Be sure to follow the steps to add the Workers Comp Code and assign the WC Code to a Job Code, etc.
