The easiest way to create a new code is to find a code that uses the same GL and taxing. You would bring that code up from Deduction & Benefit Code Maintenance (KE0036) and choose More and then Save as.
It will ask if you want to use the next available number or you can choose No and key a specific number you prefer.
It will ask for a unique Abbreviation. In my example I am using is AFLPT for AFLAC Pretax.
Your new code is now created. Clear out of the current code and bring up the new code. Make any changes needed, I changed the highlighted in my example.
Click on the rates tab and enter the Employee and Employer cost if applicable.
Ok out and click on the Accounting tab. Make any GL changes and you can link it to the vendor being paid. Add any W2 Coding if applicable.
If it is a Health Insurance code and you create ACA 1095’s through Keystone you would also want to go to the Benefits Tab and mark it as a Valid Employee Benefit and Plan Type Health.
If you prefer to enter it all from scratch you would complete the same screens but instead of starting with an existing code and saving you would use the New Record key (highlighted) or key the number you want to use on a blank Deductions and Benefit Code Maintenance screen.
