FAQ — TAX PREPARATION IN WASHINGTON
Does Washington have a state income tax?
No — Washington has no personal state income tax.
Do I still need multi-state filing?
Often yes — especially for tech employees connected to CA, NY, TX, or remote work.
How are RSUs taxed in Washington?
RSUs are taxed federally and often involve multi-state complications depending on where vesting occurred.
Do international workers need special tax handling?
Yes — especially H1B, TN, O1, L1, and OPT workers with foreign assets or income.
As a small business owner in Seattle, how will the new state capital gains tax affect my 2026 tax filings, and are there any exemptions I should be aware of?
For 2026, Washington’s capital gains tax of 7% on gains exceeding $250,000 from the sale of long-term capital assets will apply. While this primarily targets high-value assets, small business owners should assess if selling business assets or certain investments triggers this. Exemptions exist for real estate, retirement accounts, and certain small business sales, but careful evaluation with a tax professional is recommended.
I'm a remote worker for a California company but live in Spokane. Do I need to worry about any Washington-specific payroll taxes beyond federal withholdings for 2026?
Yes, even without a state income tax, Washington employers (or your California employer if they have a Washington nexus) are required to withhold for the Washington Paid Family and Medical Leave (PFML) program. Additionally, depending on your income, you might be subject to the Washington Long-Term Care (WA Cares Fund) payroll tax, though there are exemptions for those with private long-term care insurance purchased before November 1, 2021.
When is the deadline to file my 2026 Washington Business & Occupation (B&O) tax return if I'm a quarterly filer in Tacoma?
For quarterly filers in Tacoma, your 2026 Washington B&O tax returns are generally due on the last day of the month following the end of the quarter. For instance, the first quarter (January-March) return would be due April 30, 2026, and the second quarter (April-June) would be due July 31, 2026. Be mindful of potential local Tacoma business license renewals as well.
Can I deduct the cost of my ferry commute from Bainbridge Island to Seattle on my 2026 Washington tax return, even without a state income tax?
While Washington does not have a state income tax from which to deduct commuting expenses, you might be able to deduct certain unreimbursed employee business expenses, including some transportation costs like ferry fares, on your federal tax return if you itemize deductions and meet specific IRS criteria. However, the 2017 Tax Cuts and Jobs Act significantly limited these deductions for most employees, so consult with a tax professional to determine eligibility for 2026.
