OKLAHOMA CITY (AP) — Oklahoma revenue officials are likely to declare a revenue failure when a state board meets Tuesday to certify the amount of money lawmakers have to appropriate next year.

Preliminary figures from the Office of Management and Enterprise Services indicate that collections by the general revenue fund are projected to fall 5.7 percent below estimates for the fiscal year ending June 30.

Finance officials are forced to declare a revenue failure when collections fall more than 5 percent below estimates. Following such a declaration, the Oklahoma Constitution requires that funds allocated to state agencies be reduced by the amount necessary to bring spending into balance with actual revenue collections.

OMES's proposed revenue certification for the fiscal year that begins July 1 indicates revenue growth will not be sufficient to trigger an individual income tax cut scheduled to go into effect in 2018.
