Is an S-Corp election worth it in Washington?
An S-Corp election in Washington typically makes sense when:
- Your business net profit is roughly $40,000 or more per year
- You can pay yourself a reasonable salary plus take distributions
- You are willing to run payroll (required for S-Corp owners)
- You file your S-Corp tax return by March 15 each year
The savings come from splitting your income between W-2 wages (subject to FICA) and S-Corp distributions (not subject to self-employment tax). Use our S-Corp savings calculator to see your specific number.
Washington S-Corp election: step-by-step
- Have an eligible entity. Your Washington LLC or C-Corporation must already exist. Form an LLC or form a corporation first if needed.
- Confirm eligibility. All shareholders must be US persons (no corporations, partnerships, or foreign nationals), and you must have 100 or fewer shareholders.
- File IRS Form 2553. Submit within 2 months and 15 days of the tax year you want the election to take effect, or by March 15 of the current year.
- Check Washington state requirements. Some states require a separate state-level election. Washington's tax treatment is none (no state income tax).
- Set up payroll. S-Corp owners must take a reasonable salary subject to payroll tax. Our payroll partners handle setup.
- File annual S-Corp returns. Form 1120-S federally and Washington state returns by March 15 each year.
