An error occurs when a State or local government entity begins withholding and reporting
            wages for employees for whom there is no basis for coverage.
         
         A State or political subdivision may have made reports and payments for Social Security
            coverage of its employees to the Internal Revenue Service (IRS), under the Federal
            Insurance Contributions Act (FICA), in the mistaken belief that such action was sufficient
            to provide coverage for its employees. Reporting may be erroneous for Section 218
            purposes even if, at the time of the error, the employee is eligible to receive provisional
            coverage under the Section 210 mandatory rules. The nature of the error depends on
            the entity’s belief and intent, which may be inferred from the circumstances.
         
         Where the employer made payments with the intent to cover employees and in a good
            faith belief that the payments were sufficient to establish that coverage, the State
            may correct the error in order to preserve coverage for the period during which the
            error occurred. The State is not required to correct the error.
         
         To correct the error, the State may provide retroactive coverage through either an
            Error Modification or a regular Section 218(e)(3) Modification. Alternatively, if
            the State does not wish to correct the error, it may still pursue a standard Modification
            with the standard retroactivity options (see SL 30001.375).
         
         If the error involves a retirement system position, the State must comply with the
            referendum procedures before executing an Error Modification or a Section 218(e)(3)
            Modification. If no position was under a retirement system at the time the error was
            made, the coverage group would be covered as an absolute coverage group under Section
            218(b)(5) of the Act and a referendum would not be necessary.
         
         The State’s options to correct the error are described below.
