Updated – More States Aim to Increase Taxes on Millionaires by Karen A. Lake, CPA

Posted on January 05, 2021 by Karen Lake

In 2020 New Jersey became the fourth state in the U.S. to raise taxes on some of its wealthiest residents. Under the law, the state’s top marginal tax rate of 10.75 percent will apply to annual earnings of $1 million or more effective for tax years starting on Jan. 1, 2020. Previously, taxpayers with annual gross income of between $1 million and $5 million were subject to a top rate of 8.97 percent, and the higher 10.75 percent rate did not kick in until earnings reached $5 million.

As states across the nation struggle with budget shortfalls in the wake of the COVID-19 health crisis, many are considering similar tax hikes on their high-net-worth residents. What does this mean for individuals and business taxpayers in those states?

The State of Millionaire Taxes in the U.S.

New Jersey’s millionaire tax is  the second highest in the nation behind California, which currently imposes a top marginal tax rate of 13.3 percent on individual taxpayers with annual earnings of $1 million or more ($1.145 million for married couples filing joint tax returns). Other states with millionaire taxes already in place include Washington, D.C., with an 8.75 percent tax rate on individuals with annual income above $1 million, followed by New York with a top tax rate of 8.82 percent on individuals earning $1,077,550 or more. In Connecticut, the top tax bracket of 6.99 percent kicks in when married couples filing joint tax returns reach the $1 million income threshold.

With New Jersey’s slow but ultimate success at increasing taxes on its top-earning residents, other states are following suit.

In addition, taxpayers in nine states will be voting on a variety of tax-related ballot measures in the upcoming general election. This includes the following:

Tax hikes on top earners is nothing new. Several states raised taxes on their wealthiest residents during and even after the most recent recession, and the issue has played out on the national level during this year’s Presidential election. However, such activity highlights the challenges of tax competition across state borders and the risks and rewards governments must consider before raising taxes to fill budget gaps.

Traditional thinking has held that a tax on millionaires will strip significant revenue from a state’s tax base by pushing wealthy residents (with the ability to pay higher taxes) to move their families and businesses to more tax-friendly jurisdictions. While it is true that millions of people move each year to states with lower tax rates or no personal income tax, such as Florida, Nevada or Tennessee, a 2014 study conducted by Stanford University found little evidence to support claims that wealthy taxpayers permanently relocated to another state due to modest tax increases of as much as 3 percent in their home states. Moreover, a report issued this year by the Institute on Taxation Economic Policy (ITEP) found that during the first year of the Tax Cuts and Jobs Act, which capped the federal tax deduction for state and local tax at $10,000, New York and California added the most new millionaires to their tax base.

Because high earners are often too embedded in their home states to simply pack up and leave, some will acquire second or third homes in low or no tax states and attempt to establish permanent legal residence (domicile) there. For example, a New Jersey resident hoping to establish domicile in Florida for income-tax purposes must meet a series of benchmarks to demonstrate intent and proof of residency, including, but not limited to, getting a Florida driver’s license, registering to vote in the state and spending the required minimum 183-days there.

By contrast, families planning a move to another state may consider local taxes in their decision-making process, but the ultimate choice should be dependent on where the family can live its best life and achieve their needs and goals. In all matters involving personal and business finances, taxpayers should consult with their professional CPAs and advisors to ensure that they implement strategies that comply with federal and state regulations while ensuring tax efficiencies across state borders.
