So what are the categories you place on the chart of account for the Solo 401k? The client uses ADP to pay themself but the 401K is with ETrade. All contribution by employer are sent directly to ETrade from business bank account while the employee writes checks from their personal bank account for the employee contributions. So all I'm doing is posting the employer side on the business books. Independent of the payroll journal entry from ADP. I only have "401k Company Match" as a other current liability which is post to, is that right? The number is negative.
