I am new to Peachtree and am trying to setup taxable and nontaxable benefits. The only way that I can get a paycheck to add the taxble or nontaxable benefit to the gross income to be calculated for Incometax is by creating the benefit as a memo field in the default EmployEE fields. The problem is that this transaction does not show up in the General Ledger. I have tried to do this by creating a Field with a GL account in the default EmployEE section but then it adds the benefit to the employee's paycheck. How do I get the benefit to be added to the Gross for calculation of Income Tax but not actually have the benefit added to the employee's pay and still have it go to the GL account for payment to the benefit provider ie. Dental benefits?
