Application-2011 1st sp.s. c 19: "This act applies to amounts received by a taxpayer on or after August 1, 2011." [ 2011 1st sp.s. c 19 s 4.]
Findings-Refund of taxes-Effective date-2002 c 314: See notes following RCW 82.04.4311.
Findings-2001 2nd sp.s. c 23: "The legislature finds that the deduction under the business and occupation tax statutes for compensation from public entities for health or social welfare services was intended to provide government with greater purchasing power when government provides financial support for the provision of health or social welfare services to benefited classes of persons. The legislature also finds that both the legislature and the United States congress have in recent years modified government-funded health care programs to encourage participation by beneficiaries in highly regulated managed care programs operated by persons who act as intermediaries between government entities and health or social welfare organizations. The legislature further finds that the objective of these changes is again to extend the purchasing power of scarce government health care resources, but that this objective would be thwarted to a significant degree if the business and occupation tax deduction were lost by health or social welfare organizations solely on account of their participation in managed care for government-funded health programs. In keeping with the original purpose of the health or social welfare deduction, it is desirable to ensure that compensation received from government sources through contractual managed care programs also be deductible." [ 2001 2nd sp.s. c 23 s 1.]
Effective date-2001 2nd sp.s. c 23: "This act is necessary for the immediate preservation of the public peace, health, or safety, or support of the state government and its existing public institutions, and takes effect immediately [July 13, 2001]." [ 2001 2nd sp.s. c 23 s 4.]
