It's the second time in a month that the payments were postponed.
Budget Director Duane Goossen said Wednesday that the state also delayed $31 million worth of tax refunds from June into next week.
Kansas ended its 2009 budget year Tuesday with tax collections falling about $126 million short of expectations.
The $73 million in aid to school districts was supposed to be distributed in the final 11 days of June. Goossen said he expects the payments to be made next week.
Previously, $130 million in payments to schools were delayed from June 1 to Tuesday.
