NFCU's 3% for 12 months CD requires you to have direct deposit or payroll allotment with them.
Certificate owner(s) age 18 and older must have a Direct Deposit of Net Pay or a payroll allotment and a Navy Federal checking account within 90 days of the certificate issue date. If these requirements have not been satisfied by the 90th day, your Special EasyStart Certificate dividend rate will be reduced to the prevailing dividend rate of the standard EasyStart Certificate for the remainder of the certificate's term.
