Employers are required to keep this certificate on file. If the employee is believed to have claimed more exemption than legally entitled or claims 8 or more dependent exemptions, the employer should contact the Department at the following address or phone number for ver- ification: Alabama Department of Revenue, Withholding Tax Section, P.O. Box 327480, Montgomery, AL 36132-7480, by phone at (334) 242-1300, or by fax at (334) 242-0112. If the employee does not qualify for the exemptions claimed upon verification, the employer is re- quired to withhold at the highest rate until the employee submits a corrected Form A4 reflecting the proper exemption they are entitled to claim.
