check out the article 10287 on the knowledgebase, I think that is what you are looking for.

Hello Erik79,

I tried the setup based on the knowledge base.
Is it correct?

Section I: Creating a Group Deduction
Add deduction: $20 for employee contribution
Linked account: Health care payable

Section II: Creating a Group Benefit
Add income: $40 for employer portion
Linked account: Wage expenses

Section III: Creating the Employers Expense
Add other expenses: health care for $40
Linked account: Payables: Health care payable and Expenses: Health care expense

Also, which code should I set for payment adjustment?

Thanks,

Kaz
