LLC taxes in Washington
Washington has no individual income tax on earnings.
An LLC is a legal structure, not a tax structure. By default the IRS taxes a single-member Washington LLC like a sole proprietorship, so every dollar of profit carries the 15.3% self-employment tax on top of income tax.
An S-corp election moves part of that profit out of payroll tax by paying yourself a defensible salary. The savings are federal — Washington income tax still applies to the whole profit — and they only clear the cost of payroll, quarterly 941s and an 1120-S return once profit is high enough.
Frequently asked questions
How much tax does an LLC pay in Washington?
A default Washington LLC pays no entity-level federal tax — profit flows to your personal return, where it faces 15.3% self-employment tax and federal income tax after the QBI deduction. Washington charges no individual income tax, so only federal income tax and the 15.3% self-employment tax apply.
Is an S-corp election worth it in Washington?
The savings are federal payroll tax, so the crossover in Washington is the usual one: roughly $80,000–$100,000 of profit, where payroll-tax savings outrun the $1,200–$2,500 a year of payroll and 1120-S costs.
What is a reasonable S-corp salary in Washington?
What you would pay an unrelated person to do your job in your Washington market, supported by pay data and hours worked. An artificially low salary to shift profit into distributions is a well-known audit trigger.
Does an Washington LLC owe quarterly estimated taxes?
The owner does, federally, once expected tax reaches $1,000. There is no Washington income tax estimate for earned income.
Are there local taxes on LLC income in Washington?
Business & occupation tax applies to gross receipts for many services.
