P.L. 106-170 extends a number of tax provisions that were due to expire by January 1, 2000. OMB estimates that the extension of these provisions reduces revenue by $2.3 billion in 2000 and $20.6 billion over the years 1999 through 2004. In 2000, this revenue loss is offset by increasing the estimated "safe harbor" tax payments for individuals with adjusted gross income of over $150,000 and other revenue changes. P.L. 106-170 also improves work incentives for individuals with disabilities, such as establishing a ticket to work and self-sufficiency program and expanding health benefits for certain individuals. On net, OMB estimates that the Act increases on-budget outlays by $23 million over the pay-as-you-go window. The Act also yields net savings in off-budget accounts, which are not scored for pay-as-you-go purposes.

5. CBO ESTIMATE:

	1999	2000	2001	2002	2003	2004

Other revenues................	0	-2,099	-1,653	1,742	-429	-222
Outlays............................	0	18	52	-16	13	46

6. EXPLANATION OF DIFFERENCES BETWEEN OMB AND CBO ESTIMATES:

Over the period 1999 through 2004, CBO estimates net pay-as-you-go costs of $15.5 billion for P.L. 106-170; while OMB estimates $17.9 billion. Most of this difference is the result of different scoring of tax extension provisions, primarily for extensions of the research and experimentation tax credit and Subpart F for active financing income. These differences are the result of different baselines and estimating models.
