Here’s your Seattle/Bellevue Multi-State Tax Checklist — designed to help you quickly spot when you might owe taxes or have filing obligations outside Washington.
1. Income From Working in Another State
Check if:
-
You physically worked in another state, even for a few days.
-
You were a remote employee for a company based in a state with income tax.
Example:
You live in Bellevue but commute to Portland, OR a few days each month. Oregon will likely require a nonresident income tax return for those wages.
2. Rental or Property Income
Check if:
-
You own real estate outside Washington that produces rental income.
-
You sold property in another state.
Example:
A Seattle resident who rents out a vacation home in Idaho must file in Idaho for that rental income.
3. Business Operations Across State Lines
Check if:
-
Your business has clients, sales, or inventory in another state.
-
You have employees or contractors working from another state.
-
You attend trade shows or perform services in another state.
Example:
A Bellevue marketing consultant who spends a week working onsite for a California client could create tax nexus in California.
4. Investments and Pass-Through Business Income
Check if:
-
You’re a partner in a partnership or member of an LLC operating in another state.
-
You receive K-1 forms showing income from out-of-state operations.
Example:
Seattle investor in a Colorado real estate LLC will likely need to file a Colorado nonresident return.
5. Recent Move Into Washington
Check if:
-
You lived in a state with income tax earlier in the year.
Example:
A new Seattle resident who moved from New York in June must file a part-year NY return for January–June.
6. Sales Tax & Marketplace Sales
Check if:
-
You sell physical products to customers in other states.
-
You use platforms like Etsy, Amazon, or Shopify that collect out-of-state sales tax.
Example:
A Bellevue-based Etsy shop selling to California customers may have to register for a California sales tax permit, depending on sales volume.
Quick “Washington Resident” Rule of Thumb
