Self Employed 401k - Fidelity Question
I am planning to open a self employed 401k through fidelity. I am self employed and have an LLC taxed as an S-corp and I am the only employee. I have a biz account with BOA and a personal account with BOA as well. I run my payroll through ADP. I pay myself a salary through that W-2 and I actually withhold almost all of the payroll instead of making estimated payments (its cleaner and easier for me).
I am a bit confused on the mechanics of making employee and employer contributions to the 401k? I thought that the employee contribution needs to be a part of payroll? If so how do I set this up through ADP? I see I can set up a "misc" deduction. If I wanted to do $1,000/payroll for employee 401k contribution can I just set this to $1,000 misc deduction and then move it to personal account and from there move to fidelity?
