Washington State Taxes Explained: A Comprehensive Guide - Realtor Cas Cassandra Marks

QUICK ANSWER: Washington relies on sales tax (6.5% base, up to 10.4% combined), property tax (capped at 1% annual increase without voter approval), and Business & Occupation (B&O) tax on business gross receipts rather than a broad personal income tax. As of March 2026, Washington signed SB 6346 into law under Governor Bob Ferguson, a 9.9% tax on household income above $1 million, effective 2028 - the state's first personal income tax in roughly 90 years, currently facing legal challenges. Capital gains above a roughly $278,000 annual exemption are taxed at 7% (9.9% above $1 million since 2025); real estate sales and retirement account withdrawals are exempt. Real Estate Excise Tax (REET) is graduated: 1.1% up to $525,000, rising to 3% above $3,025,000, plus local add-ons.

Welcome to the Evergreen State, where natural beauty meets an intriguing tax landscape. Washington has long been known for its lack of a personal or corporate income tax, but that doesn't mean tax considerations are simple — and as of 2026, the picture has changed for high earners. From sales tax to property tax, capital gains to business excise tax to a brand-new income tax on million-dollar-plus households, Washington's system has a lot to unpack. This guide walks through the key components, including the state's most significant tax change in nearly a century.

Quick note: I'm a REALTOR®, not a CPA or tax attorney. This is meant to help you understand the landscape and ask the right questions — always verify specifics with a licensed tax professional.

🗺️ The Big Picture

Washington's Unique Tax System

Washington's tax structure has long stood out for one key reason: no broad personal income tax. Unlike many states, Washington historically hasn't imposed income taxes on wages or business profits, making it particularly appealing for high-income earners, investors, and businesses. This is offset by reliance on other forms of taxation, including sales tax, property tax, and business taxes — and, as of March 2026, a targeted income tax on the highest-earning households.

🛍️ Sales Tax

Sales Tax in Washington

Washington is heavily dependent on sales and use taxes for its revenue. The base sales tax rate is 6.5%, but local jurisdictions can add additional taxes, making the total rate as high as 10.4% in certain areas. In Vancouver, for example, the combined rate is around 8.7–8.8%. While most goods and services are taxed, some essential items, such as groceries and prescription medications, are exempt.

The state's sales tax is particularly important for residents to understand, as it applies to a wide range of purchases, including items like furniture, clothing, and electronics. Knowing the sales tax rate in your area can help with budgeting, especially for larger purchases.

🏢 B&O Tax

Business and Occupation (B&O) Tax

Washington does not impose a corporate income tax, but instead uses a Business and Occupation (B&O) tax, which is levied on the gross receipts of businesses operating in the state. The B&O tax is calculated on the total revenue a business generates, and the rate depends on the type of business activity. Retail, wholesale, and service businesses each have different rates. For small businesses, the tax can be substantial, but there are exemptions and credits available depending on your business type.

🏡 Property Tax

Property Tax in Washington

Washington's property taxes are based on the assessed value of real and personal property. The state constitution caps regular property tax levies at 1% growth annually without voter approval. However, voters in certain areas may approve additional levies for specific purposes like school funding or public safety.

In Clark County, where Vancouver is located, property tax rates are determined by the assessed value of the property and the district's needs. These taxes help fund essential local services, including schools, parks, and emergency services.

📈 Capital Gains

Capital Gains Tax

In 2021, Washington passed a capital gains tax targeting high earners. This tax is a 7% levy on the sale of long-term capital assets, such as stocks and bonds, with roughly the first $278,000 in annual gains exempt (the original $250,000 threshold adjusts for inflation each year). Real estate transactions and sales from retirement accounts are exempt from this tax. In 2025, the state added an upper tier: gains above $1 million are now taxed at 9.9% instead of 7%. Although the capital gains tax has been controversial and faced legal challenges, it was upheld by the state Supreme Court, marking a significant shift in Washington's tax policy that helped pave the way for the 2026 income tax.

⚡ New in 2026

Washington's New Income Tax: SB 6346

This is the most significant change to Washington's tax code in nearly a century. In December 2025, Governor Bob Ferguson announced his support for a "millionaires' tax" targeting the state's highest earners, citing Washington's regressive tax structure — where, according to Ferguson's office, the bottom 20% of earners pay about 13.8% of their income in state and local taxes, versus just 4.1% for the top 1%.

The Legislature passed the bill in March 2026, and Ferguson signed SB 6346 into law on March 30, 2026. It establishes a 9.9% tax on household income above $1 million per year, effective January 1, 2028, with the state not expecting to collect revenue until 2029 to allow time for expected legal challenges to play out. Only the amount above $1 million is taxed — a household earning $1.1 million owes 9.9% on $100,000, not the full amount — and married couples share a single $1 million threshold. Ferguson's office estimates the tax affects fewer than 0.5% of Washington households and will raise $3–4 billion per year.

💡

What this means for most residents: If your household income is under $1 million, this tax does not apply to you, and Washington's traditional no-income-tax advantage over states like Oregon remains intact. It matters more as a precedent — Washington's constitutional bar on income taxes has now been navigated once, and where that threshold goes over the coming decades is a legitimate question for long-term planning.

🔍 Wealth Tax vs. Income Tax

Was There a Washington Wealth Tax Proposal? Clearing Up the Confusion

It's worth distinguishing two different ideas that get conflated: a true wealth tax (based on someone's total net worth) and the income tax that actually passed (based on annual income). Some Washington legislators did push for a net-worth-based wealth tax to help balance the state budget. Governor Ferguson rejected that approach, calling it untested and warning it could get tied up in court without delivering needed revenue.

What Ferguson proposed instead — and what became law — was the income-based millionaires' tax described above (SB 6346), taxing annual income over $1 million rather than someone's overall net worth. So while Washington does not have a wealth tax, it does now have a targeted income tax on the highest-earning households.

⛽ Gas Tax

Gasoline Tax and Excise Taxes

Washington has one of the highest gasoline taxes in the nation. As part of the 2025–2026 tax package, the base gas tax rose 12% to 55.4¢ per gallon, and the state's carbon pricing program (CCA) adds a further surcharge as companies pass emissions costs to consumers — pushing the real cost at the pump meaningfully higher than in neighboring Oregon. The legislature also built in an automatic 2% annual increase going forward. This revenue plays an essential role in funding the state's infrastructure, including road repairs, bridges, and public transportation systems.

🏘️ Real Estate Excise Tax

Real Estate Excise Tax (REET)

When buying or selling property in Washington, Real Estate Excise Tax (REET) applies — and it's graduated, meaning it increases based on the value of the property being sold:

1.1% on the portion of the sale price up to $525,000
1.28% on the portion from $525,000 to $1,525,000
2.75% on the portion from $1,525,000 to $3,025,000
3.00% on the portion above $3,025,000

Local jurisdictions, including Clark County, can add a local REET on top of the state rate. REET is generally paid by the seller at closing, though the tax can create a lien on the property if unpaid. This is important for homeowners, buyers, and sellers to factor into their net proceeds when engaging in real estate transactions.

💵 Relief Programs

Washington's Tax Exemptions and Relief Programs

Though Washington's tax system is complex, there are exemptions and relief programs designed to help residents. For instance, seniors and disabled persons with limited income may qualify for property tax exemptions or reductions. Additionally, landowners who preserve farmland or timberland may benefit from tax incentives under the Open Space Taxation Act.

Sales Tax Exemptions

Groceries, prescription medications, and medical equipment are exempt from Washington sales tax.

Property Tax Relief Programs

The Senior and Disabled Persons Property Tax Exemption helps low-income individuals, and the Open Space Taxation Act benefits landowners preserving agricultural or recreational land.

Key Filing Deadlines

Although Washington does not require broad personal income tax filings, businesses must comply with various tax deadlines, including quarterly Business and Occupation (B&O) tax filings, and the standard federal tax filing deadlines still apply to Washington residents each year. Businesses may apply for extensions on B&O filings through the Washington Department of Revenue if needed. Once SB 6346 takes effect for the 2028 tax year, affected households will also have new state filing obligations starting in 2029 — details on that process are still being finalized by the Department of Revenue.

✅ Final Thoughts

Final Thoughts on Washington State Taxes

Understanding Washington's tax system is essential for anyone considering a move to the Evergreen State. For the vast majority of residents, the no-income-tax advantage, relatively stable property taxes, and reliance on sales and excise taxes still define a tax-friendly environment. The new SB 6346 income tax changes the picture only for households earning above $1 million a year — but it's a meaningful precedent worth understanding regardless of your income level. Whether you're looking to buy real estate in Vancouver WA, relocating to Clark County, or exploring tax advantages for your business, Washington remains an appealing option for most people.

Are there tax breaks for small businesses in Washington?

Yes, Washington offers B&O tax credits for small businesses that earn under certain thresholds, along with industry-specific exemptions.

What taxes do I pay when buying or selling property in Washington?

When you sell property in Washington, the Real Estate Excise Tax (REET) applies, using a graduated rate: 1.1% up to $525,000, 1.28% from $525,000 to $1,525,000, 2.75% from $1,525,000 to $3,025,000, and 3% above that, plus any local REET add-on.

Is Washington a tax-friendly state?

Yes, in some ways, for most residents. Washington remains tax-friendly for the vast majority of earners and for retirees, since there's still no tax on wages under $1 million or on retirement income. However, it has one of the highest sales tax rates in the U.S., which can be burdensome for lower-income households.

How much is $100,000 after taxes in Washington state?

At $100,000, you're well under the $1 million threshold for Washington's new income tax, so your primary deductions remain federal income tax, Social Security, and Medicare. On average, someone earning $100,000 could take home around $75,000–$80,000 after federal deductions.

Why did Washington historically have no state income tax, and what changed?

Washington historically chose to fund its government through sales and excise taxes rather than income tax, and multiple attempts to enact a broad income tax were rejected by voters or challenged in court. That changed in March 2026 when Governor Ferguson signed SB 6346, a 9.9% tax on household income above $1 million, effective 2028 — the state's first personal income tax in roughly 90 years, though it's currently facing legal challenges.

What taxes do you not pay in Washington?

Residents with household income under $1 million pay no state income tax. There's also no tax on retirement income like Social Security or pensions, and real estate sale gains are exempt from the state's capital gains tax.

What are the tax advantages of living in Washington state?

Key tax advantages include no personal income tax for household income under $1 million, no tax on retirement income, and no local income taxes. This setup is often beneficial for retirees, remote workers, and business owners, though high earners above $1 million should factor in the new SB 6346 income tax starting in 2028.

What are the main types of taxes in Washington state?

The main tax categories are sales and use tax, property tax, and Business & Occupation (B&O) tax. Starting in 2028, a new state income tax on household income above $1 million (SB 6346) adds a fourth category for high earners.

What is the cost of living in Washington state?

Washington's cost of living is above the national average, especially in cities like Seattle and Bellevue. However, areas like Vancouver and Spokane offer a lower cost of living with the benefit of no state income tax for the vast majority of earners.

Do you pay property taxes in Washington state?

Yes. Property taxes in Washington are collected at the county level and are based on assessed property value. Rates vary by location, with Clark County and King County among the highest.

What taxes come out of my paycheck in Washington state?

For household income under $1 million, Washington doesn't deduct state income tax from paychecks. Typical deductions include federal income tax, Social Security tax (6.2%), and Medicare tax (1.45%). Employers may also withhold for unemployment insurance and benefits.
