2012 Tax exemption study

A Study of Tax Exemptions, Exclusions, Deductions, Deferrals, Differential Rates and Credits for Major Washington State and Local Taxes

Research and Fiscal Analysis Division:
Kathy Oline, Assistant Director

Estimates contained in the 2012 Exemption Study reflect the savings to taxpayers and do not necessarily indicate the potential revenue which might accrue to governmental jurisdictions in the absence of the exemptions. The estimates are provided in terms of accrued tax liability and the actual cash receipts during a particular biennium might be lower as a result of initial compliance factors. All estimates contained in this report are based on the June 2011 Economic and Revenue Forecast Council forecast. The estimates contained in this study are not updated as new forecasts are released. Rather, this study should be viewed as a point in time estimate.
