O.C.G.A. § 28-5-53 (2019)

(a) A fiscal note that is attached to a bill or joint resolution shall be revised by the commissioner at each successive stage of the legislative process in which an amendment is adopted that changes the fiscal effect of the bill or joint resolution, unless this requirement is waived by the President of the Senate, by a majority vote of the Senate, by the Speaker of the House of Representatives, or by a majority vote of the House of Representatives. A revised fiscal note shall not be required for any amendment which either increases local revenues or decreases mandated expenditures.

(b) The revised fiscal note shall be processed by the commissioner and returned as quickly as possible to the committee or the Clerk of the House of Representatives or Secretary of the Senate if either the Clerk or the Secretary has the custody of the bill or joint resolution at that time.

(c) Except as otherwise provided by subsections (a) and (b) of this Code section, a waiver of a fiscal note shall be replaced at any time with a fiscal note if an amendment to a bill or joint resolution causes the bill or joint resolution to have an effect upon the revenues or expenditures of local political subdivisions.
