Suppose an employee has a yearly salary of $100K and his/her company matches "50 percent match up to the first 6 percent", and the employee is contributing at a rate of 40%. The employee will reach his/her IRS limit of $19K by 6 months.
So for the last six month there will be no 401K deduction from his own salary. The question is, will the company will still match, or will the employee lose the 401K match for last 6 months?
