Capital gains tax not 'excise' tax

Last week, the state Supreme Court heard oral arguments concerning the capital gains income tax. I attended the hearing in person.

It is unclear when the court will issue its opinion. The capital gains income tax is first owed on April 18, 2023. There are three possible rulings the court could issue.

One possible outcome is for the state Supreme Court to catch the Hail Mary pass thrown by income tax advocates and by judicial fiat now allow a graduated income tax without a constitutional amendment. This is the preferred course of the Washington Education Association teachers union and other interveners who argue income isn’t property.

This strategy is being pursued by income-tax advocates because state voters have already rejected six constitutional amendments to allow a graduated income tax (10 straight income tax proposals rejected including initiatives).

As explained by Sen. Jamie Pedersen in this 2018 email obtained by a public records request:

“But the more important benefit of passing a capital gains tax is on the legal side, from my perspective. The other side will challenge it as an unconstitutional property tax. This will give the Supreme Court the opportunity to revisit its bad decisions from 1934 and 1951 that income is property and will make it possible, if we succeed, to enact a progressive income tax with a simple majority vote.”

This effort to have the court change prior rulings and now say Washingtonians don’t own their income has consistently been rejected by the courts. In fact, on Sept. 13, 1960, the state Supreme Court issued a unanimous one-page ruling with this sage advice: Don’t ask the court to reverse its numerous rulings prohibiting a graduated income tax; instead amend the constitution:

“The argument is again pressed upon us that these cases were wrongly decided. The court is unwilling, however, to recede from the position announced in its repeated decisions.

“Among other things, the attorney general urges that the result should now be different because the state is confronted with a financial crisis. If so, the constitution may be amended by vote of the people. Such a constitutional amendment was rejected by popular vote in 1934.”

Another possible outcome is for the justices to decide that Washington alone has discovered how to tax income as an excise tax and that this a valid excise tax.

Should that occur, however, there is the potential for a federal lawsuit for violation of the U.S. Commerce Clause. While states can tax income across state lines, they are prohibited from taxing activity that occurs in other states.

If the capital gains tax is found to be an “excise tax,” Washington would be attempting to tax activity that occurs in other states.

It is important to remember that no other state has a stand-alone tax on capital gains; 41 states do have personal income taxes, and as income, capital gains are included in those tax bases. This is why those taxes on capital gains income don’t run afoul of the U.S. Commerce Clause.

Attempting instead to tax activity that occurs in other states (an “excise tax”) raises federal constitutional concerns.

There is also the possibility that if the capital gains income tax is deemed an “excise tax” by our court, taxpayers will not be able to deduct it from their federal tax burden.

According to a congressional liaison for the IRS, if the capital gains tax is upheld as an “excise tax,” taxpayers may be prevented from deducting it against their federal income tax returns:

“I conferred with our internal sources and looked into RCW 82.87.040 which reads the Capital Gains Tax is labeled as an ‘Excise Tax’ and not an ‘Income tax’. Based on PUB 17, stipulated state excise taxes is not deductible. So my preliminary answer is no, that IRS cannot interpret state excise tax into income tax and allow its deduction on federal returns.”

The IRS is crystal clear, however, on what type of tax a capital gains tax really is – an income tax.

The final possible outcome is that the court could agree with the Inslee-appointed Superior Court judge that the capital gains income tax “is declared unconstitutional and invalid and, therefore, is void and inoperable as a matter of law.”

Some have raised concerns that important programs would be at risk if the state Supreme Court overturns that capital gains income tax. Lawmakers have already made it clear, however, that the targeted spending will occur even if the tax is declared unconstitutional.

No matter what the justices decide, the fact will remain that literally every tax professional in the world, from the IRS, to every other state, to other countries will tell you the same thing – capital gains are income and taxes on them are income taxes.

Forty-nine states agree with the IRS. Other countries also agree with the IRS.

Washington State government officials, however, stand-alone claiming a capital gains tax is an “excise tax.”
