"I suggest the employer help set up payroll deduction IRAs with their own bank for any new employee who wants to defer before the one year eligibility is met. There is a rule that if an employer has reason to believe that the IRA contribution will be deductible for the employee, he doesn't have to subject that amount to withholding so it operates much like 401(k) deferrals. Most new employees won't go over the IRA cap anyway."
Larry, that's very interesting indeed. Do you know, offhand, a citation for that? Please don't take any time, I can dig around when I have a chance.
