If the tax-levying power of a special district is by law exercised on its behalf by a county or city, and if the county or city governing board has no discretion as to what rate of tax it will levy on behalf of the special district, the governing board of the district shall notify the city or county by June 15 of the rate of tax it wishes to have levied. If the district does not notify the county or city governing board on or before June 15 of the rate of tax it wishes to have levied, the county or city is not required to levy a tax for the district for the fiscal year.
If the taxes of a special district are collected on its behalf by a county or city, and if the county or city governing board has no power to approve the district tax levy, the district governing board shall adopt its budget ordinance not later than July 1 and on or before July 15 shall notify the county or city collecting its taxes of the rate of tax it has levied. If the district does not notify the county or city governing board on or before July 15 of the rate of tax it has levied, the county or city is not required to collect the district's taxes for the fiscal year.
