In a 403(b) plan, compensation means the employee's includible compensation

Required  - The amount an employer must deposit into the plan on behalf of an employee must either be a matching contribution that equals a certain portion or percentage of the employee's contributions or a minimum nonelective contribution to all plan participants.

The amount of an employer's annual contributions are determined by an actuary.

The maximum combined employer and employee contributions are for 2013 the lesser of 100% of an employee's includible compensation, or $17,500 or more if additional contributions permitted by plan (age 50+ catch-up contributions or 3 years prior to normal retirement age).
