Taxes and Interstate Migration New Jersey Department of the Treasury Office of the Chief Economist Office of Revenue and Economic Analysis
The New Jersey Tax Flight Controversy • In 2004 New Jersey sharply increased its highest tax rates: • Marginal rate on income over $500,000 was boosted from 6.37% to 8.97%. • Hughes and Seneca (2007) first documented increased outmigration from New Jersey. • Havens (2010) documented large unfavorable shift in wealth movements from New Jersey than from neighboring states. • Young and Varner (2011) document outmigration rise at upper end, but • Regard loss of tax base as very small relative to revenue gain • Argue that tax increase had little or nothing to do with outmigration • Assert high home prices in New Jersey may have spurred outmigration of the well-to-do.
Taking another look at the issue • Young and Varner • Only considered taxes and outmigration, not taxes and inmigration. • Only looked at New Jersey • Did not systematically look at the influence of housing costs
Study of Interstate Migration • Started with the IRS migration dataset. • This series presents annual state-to-state movements of taxpayers and adjusted gross income. • Assumed migrations are influenced by • Differences in unemployment rates (people likely move from high-unemployment rate to low-unemployment rate states) • Differences in home prices (people likely move from high-home price to low home-price states) • Differences in state income taxes (people likely move from high-tax to low-tax states, especially to those with no state income tax)
Results • Statistically significant effects of income tax rate differentials on annual migration. • Housing price differentials also usually significant. • People are attracted to zero income-tax states.
Implication of Results for New Jersey • Suppose NJ boosted its income tax schedule by one percentage point across the board (and no other state changes its taxes). • This would be a very large tax hike • More than twice as big as the 2004 increase. • Static revenue increase would be nearly $2 ½ billion a year. • Model suggests NJ would see increased annual net outflows of • About 4,200 taxpayers (likely about twice as many persons) • About $530 million in AGI • Average income of affected taxpayers equal to about $125,000. • Similar calculations can be made for any other state.
Calculated Effects of 2004 “Millionaires’ tax” • If NJ effective rates had remained at 2003 levels (movement since reflects bracket creep as well as changes in the law), then by 2009 • NJ would have had roughly 20,000 more taxpayers. • Adjusted gross income would be approximately $2.4 billion higher, generating more than $125 million in state income tax. • Suggests that revenue boost from 2004 increase has been partly reversed by induced out-migration of the base (as well as lessened in-migration).
Some Limitations of the Results • Model does not estimate migration effects on • Business tax revenue • Property tax revenue • Sales tax revenue • The cumulative tax losses to the state could potentially be larger than the model’s predictions
Effect of House Prices • A $10,000 increase in New Jersey home prices would be associated with a loss of 1200 taxpayers a year and $66 million in adjusted gross income. • Average income of lost taxpayers is smaller than those affected by a rate increase (about $50,000 a year vs. about $125,000 a year).
Survey Evidence • In July 2011 subscribers to the NJ Division of Taxation’s Tax E-Notes were asked about migration patterns. • Most likely, these are accountants or other financial advisers. • Approximately 200 responded. • More than half said that clients had recently left, or expressed interest in leaving the state. • Given the option to pick 5 out of a list of 11 potential reasons for outmigration, the top ones were • State income taxes (85.4%) • State property taxes (77.7%) • State estate taxes (67.0%) • Retirement (47.6%) • Housing costs (43.7%)
Conclusions • Analysis of IRS data suggests some connection between interstate tax differentials and migration patterns. • High taxes seem to be associated with loss of higher-income taxpayers. • High home prices seem to be associated with loss of middle-income taxpayers. • Application to New Jersey suggests cumulative outmigration may have offset some portion of the 2004 tax increase. • Given New York’s 2012 reduction in income taxes, sensible to be aware of the potential impact of New Jersey taxes on migration. • Survey responses suggest that New Jersey’s taxes may be on many people’s minds when making location decisions.
