BPC §7725.2: Except as otherwise provided in this chapter, a license that has expired may be renewed at any time within five years after its expiration on filing of an application for renewal on a form prescribed

Except as otherwise provided in this chapter, a license that has expired may be renewed at any time within five years after its expiration on filing of an application for renewal on a form prescribed by the bureau and payment of all accrued and unpaid renewal fees. If the license is not renewed within 30 days after its expiration the licensee, as a condition precedent to renewal, shall also pay the delinquency fee prescribed by this chapter. Renewal under this section shall be effective on the date on which the application is filed, on the date on which all renewal fees are paid, or on the date on which the delinquency fee, if any, is paid, whichever last occurs. If so renewed, the license shall continue in effect through the date provided in Section 7725 that next occurs after the effective date of the renewal, when it shall expire if it is not again renewed. If a license is not renewed within one year following its expiration, the bureau may require as a condition of renewal that the holder of the license pass an examination on the appropriate subjects provided by this chapter.
