No such professional bondsman shall charge for his commission or fee more than fifty dollars for the amount of bail furnished by him up to five hundred dollars, nor more than ten per cent of the amount of bail furnished by him from five hundred dollars up to five thousand dollars, nor more than seven per cent of the amount of bail furnished by him on sums in excess of five thousand dollars. When a professional bondsman has furnished bail to an accused in a criminal proceeding, the fee which he receives therefor shall be credited on account of his fee for any subsequent bail in an increased amount which he may furnish for the same person in the same criminal proceeding; but this provision shall not apply to bail furnished on appeal of a conviction or bindover of an accused. Each professional bondsman licensed under the provisions of this chapter shall annually, during the month of January, on forms furnished by the Commissioner of Emergency Services and Public Protection, report to said commissioner in detail the names of the persons for whom such bondsman has become surety during the year ended December thirty-first preceding, with the date, the amount of bond and the fee charged and paid and such further information as said commissioner requires.
