If the collector, while charged with the collection of insolvent taxes and taxes in litigation, shall retire from office before the expiration of the time allowed to make such collection, he shall make, to the meeting of the county commission next following the date of his retirement, the report required by Section 40-5-29, whereupon allowance must be made and certified and credits entered as provided in said section; but his successor in office must be charged with the several accounts so credited to the retiring collector and is charged with the duty of collecting, reporting, and paying the same and making final report of uncollected balance in all respects as if no change in office has been made.
