Sickness benefits are not payable for any day for which you receive sick pay from your employer. But benefits may be paid if you receive supplemental sickness benefits from your employer or an insurance company. Sick pay is a continuation of part or all of your wages while you are unable to work. Sick pay is generally subject to all regular payroll deductions. You must report sick pay on your claim form; failure to do so may result in an overpayment of RRB sickness benefits that you will have to refund.
Supplemental sickness benefits are different from sick pay. Supplemental sickness benefits are payments made by your employer or an insurance company to supplement your RRB benefits and are not subject to Tier II retirement tax. Supplemental benefits are paid under plans submitted by your employer and approved by the RRB. Do not report supplemental sickness benefits on your claim. If you do not know whether payments you are receiving are supplemental under an RRB-approved plan, contact the RRB office nearest you for assistance.
