Washington State Capital Gains Tax

What is it?

On May 1, 2021, Governor Inslee signed the Engrossed Substitute Senate Bill 5096 (RCW 82.87), which established a state-wide 7% tax on long-term capital gains. After much back and forth, on March 24, 2023, the Washington State Supreme Court upheld this legislation.

What RCW 82.87 does is impose a flat 7% tax on the sale or exchange of long-term capital assets (stocks, bonds, business interest, or other investments and tangible assets) and allocates this revenue to public education and child-care programs. It is expected to bring in approximately $1 billion in revenue to these programs over the next two years.

Income, Sales, and Excise Taxes – Oh My!

An income tax is typically based on a taxpayer’s earned wages and may be levied with progressive tax rates (in which higher income results in higher marginal tax rates), flat tax rates (where each taxpayer pays the same tax rate regardless of income), or regressive tax rates (taxpayers with higher income pay lower marginal tax rates). Think of filing your taxes at the end of the year and trying to make sense of the tax brackets applied to your W-2 income (or 1099 if you’re a contractor).

A sales tax is levied on retail sales of goods and services, typically at the point of sale as a percentage on the retail cost, is charged to the end user of a good or service, collected by the retailer, and passed on to the government. Think of buying a shirt from your favorite apparel company and taxes being applied at purchase.

An excise tax is a tax on a specific good or service at the time of purchase. They are mostly paid by merchants or businesses, who pass this on to the consumer through higher prices. Think of alcohol, gasoline, or cigarettes where the tax is baked into your price at the register or pump.

Washington State is one of few states that does not have a state income tax. Instead, the State relies on revenue generated in part by its sales and excise taxes.

Crucially, in upholding the RCW 82.87, the State Supreme Court determined that this tax is a constitutional excise tax and not an income tax, which would be prohibited under the State Constitution without an amendment to allow such a tax.

Who does this apply to?

This tax applies to:

  • Washington State residents
  • Non-Washington residents with property located in Washington
  • Both individuals and married couples with capitals gains in excess of $250,000 (that is, if married filing jointly, the threshold is still $250,000 for a couple, not $250,000 per individual or $500,000 overall)

What does this not apply to?

Most notably, this does not apply to:

  • Real estate
  • Short-term capital gains
  • Dividends or interest
  • Assets held within retirement accounts
  • Smaller family-owned businesses
  • Corporations or other entities

Hypothetical Example

Rhonda is in a period of transition. She:

  • Just retired from her employer, Kraken Tech Industries, where her compensation consisted of 20,000 stock options, currently valued at $50 per share.
  • Has a 401(k) worth $1,500,000.
  • Has a Roth IRA worth $500,000;
  • Is looking to sell her home in Redmond, valued at $2,750,000 (on which she owes no mortgage);
  • Plans to move to Ellensburg to buy a home valued at $750,000.

In addition, she owns two small rental properties in Tacoma, valued together at $1,500,000 that she no longer has the energy for managing and wishes to sell these as well.

Rhonda came to McKay Wealth Management, trying to get a handle on her situation and determine her optimal path forward. With regards to the Washington State 7% excise tax:

  • Her 401(k) and IRA, being qualified retirement assets, will not be impacted. However, they may well come with their own tax considerations and strategies.
  • Her properties, including the rental properties, being real estate, will also not be impacted. However, these too will face a myriad of consequences that she and her McKay Wealth team will navigate and develop a strategy to tackle.
  • Her 20,000 stock options, however, may well be impacted. Were these to be exercised at one time, she could be subject to up to $52,000 in capital gains excise taxes (([20,000 x $50] - $250,000) x 0.07 = $52,500). This will be a consideration for her and her McKay Wealth team as they put together her optimal path forward.

This law may be of particular interest to successful small and family-owned businesses and individuals who receive stock as part of their overall compensation package. Additional strategies, such as spreading out the timing of liquidating long-term capital gain assets or making charitable contributions to Washington State qualified charities, may be deployed against the 7% excise tax.
