(1) If any school district has issued bonds under the provisions of this article, it is the duty of the board of county commissioners of the county in which said district is situated, at the time of levying other school district taxes, to levy a tax on all the taxable property of said district at a rate sufficient to produce such amount as has been certified by the board of education of said district, for the purpose of paying bonds not yet due, as provided in section 22-42-117.

(2) Except when said school district has sufficient moneys or securities in a refunding escrow account to satisfy the bonded indebtedness obligations which will be due and payable during said district's next ensuing calendar year, if the board of education fails to certify such an amount to the board of county commissioners as required by section 22-42-117, the board of county commissioners, nevertheless, shall levy upon the appropriate taxable property of said district a tax in addition to the taxes levied for other purposes, in an amount sufficient to pay all installments of principal and interest of said bonds that shall become due during the next ensuing calendar year, or, if said bonds do not become due and payable in series at different times, in an amount sufficient to pay all installments of interest then to become due and the aforesaid portion of principal.

(3) The amount certified pursuant to section 22-42-117 and the rate of the tax levy required by this section shall be sufficient to cover any deficiency which may occur by reason of delinquent payment of taxes.

(4) The county treasurer shall not collect any fee on the moneys received by virtue of a tax levied pursuant to this section, nor shall he collect any fee on any moneys received from any other source to pay bonds or interest thereon. The county treasurer may collect a fee, as provided in section 30-1-102 (1)(q), C.R.S., for services rendered by virtue of his office having been designated as the place of payment or optional place of payment for bonds issued under this article or under article 43 of this title, but this fee shall be collected only when the county treasurer has a financial institution perform such services regarding the bonds, and such fee shall be in an amount equal to the fee charged the county treasurer by the financial institution.
