State tax filing

This is a terminology issue.

In fact, the IRS considers the sum of the employer contribution and your contribution by means of a payroll deduction program to be the "employer contribution".

This is because both of these amounts are removed from Wages in boxes 1, 3, and 5 on your W-2. So California adds the total amount back to state income.

So the program is working as the IRS and the state require.
