Finds that accountability and effectiveness are important aspects of setting tax policy. In order to make policy choices regarding the best use of limited state resources, the legislature needs information on how a tax preference is used. In recent years, the legislature has enacted or extended numerous tax preferences that require the reporting of information to the department of revenue. Although there are many similarities in the requirements, and only two distinct accountability documents, there is a lack of uniformity in the information reported, penalties for failure to file, due dates, filing extensions, and filing requirements. Greater uniformity in the data reported is necessary to adequately compare tax preference programs.

Declares an intent to create two sets of uniform reporting requirements that apply to the existing tax preferences and can be used in future legislation granting additional tax preferences.

Requires the legislative fiscal committees or the department of revenue to study many of the existing tax preferences and report to the legislature at least once. Because chapter 43.136 RCW now requires the joint legislative audit and review committee, with support from the department of revenue, to comprehensively review most tax preferences every ten years and provide a report to the legislature, a number of redundant studies by the legislative fiscal committees and the department of revenue have been eliminated. However, the department of revenue will continue to prepare summary descriptive statistics by category and report the statistics to the legislature each year.
