Whenever the commission shall function in any municipality and so long as it shall continue so to do, it may prepare and certify to the governing body of the municipality resolutions providing in substance that any and all moneys collected as taxes by the municipality over and above an amount sufficient to pay the reasonable current operating expenditures of the municipality (not including therein the principal or interest of any bonds or notes of the municipality) and such capital expenditures, if any, as may be approved by the commission as reasonably necessary to preserve the value of the taxable property within the municipality, shall be paid by the municipality to such banks or trust companies as the governing body of the municipality may designate.
