Why Choose Washington for Your LLC?
No personal income tax, home to major tech companies (Microsoft, Amazon), and a thriving Seattle startup ecosystem. Washington is a top-tier state for tech businesses.
No Personal Income Tax
Washington is one of only 9 states with no personal income tax, which means pass-through income from your LLC is not subject to state income tax. This can result in significant savings compared to high-tax states like California (13.3%) or New York (10.9%).
Washington Tax Overview
Understanding Washington's tax structure is essential for non-resident LLC owners. Here's a comprehensive breakdown of all applicable taxes.
| Tax Type | Rate | Applies to LLCs? |
|---|---|---|
| Personal Income Tax | None (7% capital gains tax on gains > $270K) | No |
| Corporate/Entity Tax | None (B&O Tax: 0.138% – 3.3% on gross receipts) | C-corps and entities with nexus |
| Sales Tax | 6.5% | If selling taxable goods/services |
| Annual Fee | $71 annual report (initial), $60 renewal | Yes |
Personal Income Tax
Washington has no personal income tax. This means that if your LLC is taxed as a disregarded entity or partnership, the pass-through income is not subject to state-level income tax. This is a major advantage for non-resident entrepreneurs who structure their US business as a single-member LLC.
Corporate / Entity Tax
Washington imposes a corporate tax rate of None (B&O Tax: 0.138% – 3.3% on gross receipts). This applies to LLCs that have elected to be taxed as C-corporations. Single-member LLCs treated as disregarded entities for federal tax purposes are generally not subject to the state corporate income tax.
Sales Tax
Washington has a state sales tax rate of 6.5%. Local jurisdictions may impose additional sales taxes. If your LLC sells taxable goods or services in Washington, you'll need to collect and remit sales tax. Remote sellers may be required to collect Washington sales tax if they exceed the state's economic nexus thresholds (typically $100,000 in sales or 200 transactions).
LLC Formation Requirements
Forming an LLC in Washington involves the following steps and costs:
- Formation fee: $200
- File with: Washington Secretary of State
- Registered agent: Required (must have a physical address in Washington)
- Operating agreement: Recommended but not always required to be filed with the state
- EIN application: Required for tax filing (Form SS-4)
Formation Tip for Non-Residents
As a non-resident entrepreneur, you'll need a registered agent service in Washington to receive legal and tax documents on your behalf. Registered agent services typically cost $50–$300 per year. You don't need to live in or visit Washington to form or maintain an LLC there.
Annual Requirements & Fees
After forming your Washington LLC, you'll need to maintain compliance with these ongoing requirements:
| Requirement | Details |
|---|---|
| Annual/Biennial Report | Due on anniversary month of formation |
| Annual Fee | $71 annual report (initial), $60 renewal |
| Registered Agent | Must maintain continuously |
| State Tax Filing | No state income tax return required |
Important Note
Washington's Business & Occupation (B&O) Tax is unique — it's levied on gross receipts rather than net income, with rates varying by business activity (e.g., 0.471% for retailing, 1.5% for services). This means even unprofitable businesses owe B&O tax. In 2022, Washington also enacted a 7% capital gains tax on gains exceeding $270,000, though its constitutionality has been debated.
Federal Tax Obligations
Regardless of which state your LLC is formed in, non-resident LLC owners must comply with these federal requirements:
- Form 5472: Required for all foreign-owned single-member LLCs to report transactions between the LLC and its foreign owner. Penalty for non-filing: $25,000.
- Pro Forma Form 1120: Filed together with Form 5472 as an information return for disregarded entities.
- ITIN (Form W-7): Non-residents need an Individual Taxpayer Identification Number to file US tax returns.
- EIN (Form SS-4): Required for all LLCs to open bank accounts and file taxes.
- FBAR (FinCEN 114): Required if your US financial accounts exceed $10,000 at any point during the year.
Key Federal Deadlines
Form 5472 + 1120: Due April 15 (6-month extension available to October 15)
FBAR: Due April 15 (automatic extension to October 15)
