Appleby is still correct. The rehired employee is eligible on their date of rehire. By allowing the 60-day period to start on the day plan notice is provided to the rehired employee (instead of the next day), a rehired former employee, for example, will not have to wait until the following year to become eligible. It would be impractical to require notice before the date of eligibility; because that day or the identity of the employee, is not always known. See SIMPLE-IRA LRM Sections 6 and 7; IRC 408(l)(2)(C) and 6693(c); ERISA 101(g).
Under the model document, the rehired employee would appear eligible (Article 1). The 60-day period to make or change the salary reduction election begins when the 60-day notice is provided (Article II(2)(a)).
Unless this employee was rehired during the same calendar year that they "made an election to terminate" their salary reduction agreement, I see no reason to make the individual wait until the following year (or next election period if sooner) to participate (with a valid SR election agreement inplace).
Hope this helps.
