Washington state’s proposed new revenue tax consists of the most important “marriage penalty” within the nation, putting greater taxes on sure {couples} who file collectively, based on tax consultants.
The state Home of Representatives accredited Washington’s first-ever revenue tax, imposing a 9.9% tax on revenue of greater than $1 million a 12 months. Having additionally handed the state Senate, it’s going to now go to the governor, who plans to signal it into regulation. Washington is at present certainly one of solely 9 states with no state revenue tax, and the brand new price can be one of many highest within the nation.
Whereas Democratic legislators name it “the millionaire’s tax,” some taxpayers making far much less as people may even be topic to the tax because of a steep marriage penalty. In keeping with the laws, the $1 million threshold for the tax applies to people, {couples} and home companions. So if a married couple every makes $600,000, their mixed revenue of $1.2 million would set off the tax.
“In keeping with the statute, it would not matter in case you’re single or married, the exemption is $1 million,” mentioned Joe Wallin, an legal professional who advises corporations and tech founders in Washington. “It must be known as the half-millionaire tax.”
Whereas marriage penalties will not be unusual in state or federal tax codes, Washington’s stands out for its measurement. Most states use two revenue thresholds for tax brackets, one for people and one other for {couples} that is normally twice as excessive. Some high-tax states, equivalent to California and New York, solely apply marriage penalties for the very best earners, based on the Tax Basis, a nonprofit tax coverage assume tank.
In New York, as an example, the revenue thresholds for every bracket are doubled for joint filers by the 9.65% price, which applies to revenue above $1,077,550 for single filers and $2,155,350 for joint filers. However for the particular millionaire surtax charges of 10.3% and 10.9% — related to these making above $5 million and $25 million in revenue, respectively — the revenue thresholds are the identical for joint and single filers.
In California, bracket thresholds double for joint filers, aside from the 1% Psychological Well being Providers Act, which applies to revenue above $1 million for each single and married filers.
Jared Walczak, senior fellow of the Tax Basis, mentioned the wedding penalties in New York and California are comparatively small, amounting to a 1% tax price distinction in California and a 0.65% distinction in New York. In Washington state, nevertheless, the distinction will be as much as 9.9%.
“In essentially the most excessive case, in case you had two single filers who each earned precisely $1 million, they might owe $0, but when they married and earned the identical revenue, they might owe $99,000,” he mentioned. “Washington’s marriage penalty would be the largest by far.”
The state’s Democratic lawmakers and governor have not particularly addressed considerations concerning the marriage penalty. State Sen. Noel Body, who leads fiscal coverage for the state Senate Democrats, mentioned the usual deduction of $1 million per family is similar construction used for the state’s capital features excise tax, handed by voters in 2021.
“As we work to make the 2 separate tax constructions work collectively, having consistency within the deduction helps with each administration of the tax by our Division of Income and ease for taxpayers,” she mentioned in a press release. “Because the tax would not apply to revenue lower than $1 million, there are various high-earning {couples} that also will not see a lot of a tax influence even when their mixed incomes are greater than $1 million.”
But in a state that will depend on extremely expert, extremely paid employees at corporations equivalent to Amazon, Microsoft and different tech corporations, many dual-income households might get hit with the tax, analysts mentioned.
“There’s this concept that, ‘We’re simply taxing wealthy dudes with yachts,'” mentioned Brian Heywood, a Washington hedge-fund supervisor who based Let’s Go Washington, a conservative political motion committee against the tax. “They have been lower than sincere with who they are going after and what the numbers are.”
Wallin joked that some dual-earning {couples} would possibly even discover a authorized divorce for tax causes, even when they need to keep successfully married. “The tax financial savings alone would greater than pay the prices of a divorce lawyer,” he mentioned.
The wedding penalty is the newest controversy for Washington’s new revenue tax, which has turn into a beacon within the Democratic Get together’s motion to lift taxes on the rich. From Rhode Island and New York to Virginia and Michigan, Democrats in state legislatures are in search of to counteract rising inequality and federal funding cuts to well being care by elevating taxes on prime earners. California is contemplating a poll initiative to create the primary state wealth tax, taxing the full internet price of the state’s billionaires.
Washington shall be a intently watched experiment within the debate over the influence of upper state taxes on wealth migration.
Two of the state’s most celebrated entrepreneurs — Jeff Bezos of Amazon and Howard Schultz of Starbucks — have already left the state for Florida, which has no revenue tax. Bezos introduced his transfer to Miami in 2023, after the state’s new capital features tax of seven% took impact. He offered greater than $9 billion price of Amazon inventory in 2024, successfully saving over $600 million in capital features taxes that he would have needed to pay to Washington state.
Schultz not too long ago introduced that he had moved from Seattle after 44 years. He mentioned his household workplace may even transfer to Miami however that his basis would proceed to function in Seattle.
“It’s our hope that Washington will stay a spot for enterprise and entrepreneurship to thrive, creating important alternative for these in Seattle and the encircling areas,” he wrote.
