Would I-645 “blow a $13 billion hole in the state budget”?
This week I saw an internet ad from the No on I-645 campaign that claims, “If passed, I-645 would blow a $13 billion hole in the state budget.” This is inaccurate and reflects a misunderstanding of our state budget. First, where is the “$13 billion” figure coming from? There’s no source listed, but a TV […]

Capital gains realizations by high earners in Washington decreased by more than in other states in 2023
As I wrote on Friday, the taxpayer migration and Statistics of Income data sets from the Internal Revenue Service (IRS) now incorporate the first few years of Washington’s capital gains tax. Although there is not yet much history, the data suggest that Washington residents may have moved or otherwise altered their behavior in response to […]

The adjusted gross income of Washington millionaires declined in 2022 and 2023
Yesterday I reviewed the economics literature on the question of whether wealthy people move in response to tax increases. It’s an important question because the revenue impact of the new income tax is uncertain. The extent to which people (and their incomes) move out of state will have implications for the state budget. Unfortunately, there’s […]

Potential behavioral responses to the income tax
With the income tax, Washington’s tax structure will become more volatile—especially because it is targeted at taxpayers with income over $1 million. The volatility makes it a difficult tax to forecast in general; for Washington, it will be especially hard to forecast in the beginning as it is a brand new tax. When it is […]

Fiscal notes and the income tax
When estimating the fiscal impact of a policy proposal, a key component is the baseline. To what is the new policy being compared? What revenues are expected under existing law, and how would the proposal change that? When agencies prepare fiscal notes during a legislative session, they all use the November revenue forecast as the […]

To make those comparisons, we adjust the data by population and by personal income. State and local taxes per capita in Washington grew […]
