William & Wall, 2019
The road from today to the years after a sale runs through Washington's rules. Here it is in the order you will meet them: where you stand, what the state takes, the rules of the sale, who buys, and what the money can do after.
Washington is a busy market for business sales, with a deep bench of buyers. The state's share of the gain is among the highest, 9.9% at the top. Expect a tax on the business itself on the way out, a tax-clearance or bulk-sale notice before closing, a licensed broker, and an estate tax to plan the proceeds around.
Tax on the gain: No income tax; a 7% tax on gains above $278,000, 9.9% above $1 million.

RCW 82.87.040 imposes 7 percent on an individual's Washington capital gains, and from 1 January 2025 a further 2.9 percent on gains above $1,000,000.
The 2025 standard deduction is $278,000 per individual or couple, and the gain from selling all or substantially all of a qualified family-owned small business is deductible.
Real estate, depreciable business assets, and retirement accounts are exempt, and from 2025 B&O tax paid on the same sale is credited against the capital gains tax.
The rate is the state's top rate on the gain for the year shown, the same figure as the indicator in the hero, so the two can never disagree.

Under contract and at closing
The rules of the sale
Selling more than half the business makes its taxes due at once and the buyer must withhold until the Department of Revenue clears the seller; a real estate licence covers sales that include real property.
RCW 82.32.140: disposing of over 50 percent of a business's assets makes tax due within ten days, and the successor withholds purchase money until a receipt or no-tax certificate.

A buyer who gives the Department written notice of the acquisition is released if no assessment against the seller issues within six months.

The real estate licensing law defines a business opportunity as a business or its goodwill when the deal includes an interest in real property, bringing such sales under licensed brokerage.

One thing you would not guess
The capital gains tax is legally an excise, not an income tax, and it reaches a grantor trust the founder set up even when federal law does not.
A non-grantor trust whose funding was an incomplete gift is treated as a grantor trust, so the founder still owes the tax on its sale gains.
Goodwill from selling a franchised auto dealership is exempt from the tax, a carve-out no other trade gets.
When the process opens
Who buys
Strategic buyers at global scale sit in the state, so mid-market founders sell into a market shaped by Microsoft, Amazon, and the software firms they spawned.

Day 0, and the years after
After the close
Washington now has the highest estate tax rate in the country: 35 percent at the top on estates over $3 million, so where a seller lives at death matters more than where the company sold.
As of October 2025 Washington taxes estates above a $3 million exemption at 10 to 35 percent, the top rate reached at $9 million.
WealthIn 2024 the exemption was $2,193,000 and the top rate 20 percent; both moved in 2025.
WealthWashington also runs a business and occupation tax on gross receipts with rates set by activity, one of only a handful of state-level gross receipts taxes.
