one of nine states
1099 Workers Comp covers a specific slice of the independent workforce, and the practical questions are always the same: what it pays, what it costs, and what changes about your taxes. This page answers those with published data rather than generalities, for Washington specifically.
Health cover and retirement, self-funded
The benefits an employer funded do not disappear when you go 1099; they move onto your own P&L. Health insurance through the individual marketplace, a retirement vehicle you contribute to yourself, and disability cover that replaces a paycheque nobody else is now guaranteeing.
The self-employed health insurance deduction lets you deduct premiums for yourself, your spouse and your dependants against income tax, above the line, without itemising. It does not reduce self-employment tax, and it is limited to your net profit from the business.
Retirement vehicles available to a 1099 contractor:
- SEP-IRA — highest contribution ceiling relative to paperwork, employer-side contributions only
- Solo 401(k) — allows both employee deferral and employer contribution, so more room at lower income
- SIMPLE IRA — lower ceiling, simpler administration, useful once you have employees
- Traditional or Roth IRA — available alongside the above, subject to income limits
- HSA, where paired with a high-deductible health plan — deductible going in, tax-free coming out for medical costs
Cover you need before the first contract
General liability cover is the one most clients require before they will sign, and many want to be named as an additional insured on the certificate. Professional liability — errors and omissions — matters where your deliverable is advice or a design rather than physical work.
Workers' compensation is the awkward one. As a sole proprietor you are usually exempt from carrying it on yourself, but clients in construction and healthcare frequently require either a policy or a state-issued exemption certificate before letting you on site, because their own coverage depends on it.
Which trades run on contractors in Washington
Across the 81 occupations 1099WORK tracks, Washington has an estimated 406,979 people working on a 1099 basis, out of 1,270,770 employed in those occupations altogether. The concentration is uneven: home health and personal care aides, software developers, and janitors and cleaners account for a disproportionate share, because those trades are structurally independent rather than incidentally so. The 1099 estimates below apply 1099WORK's per-occupation contractor share to BLS employment — they are estimates, and BLS itself does not publish the split.

Where the money is in Washington
Software Developer leads on median pay in Washington at $166,910. The table below is filtered to occupations where independent work is genuinely common — a high median in an occupation that is 95% W-2 is not an opportunity. Remember that every figure is a W-2-and-1099 blend: to match them as a contractor, multiply by roughly 1.33 for payroll tax, unpaid time and self-funded benefits.

What the tax side looks like in Washington
Nothing is withheld from a 1099 payment. You pay self-employment tax at 15.3% on 92.35% of net profit, plus income tax, in four estimated payments a year. Washington levies no state income tax, so the federal bill is close to the whole picture.
Where to look next
1099WORK is a marketplace built for 1099 engagements specifically: companies post a defined scope, independent contractors keep one verified profile, and agreements, onboarding and payment happen in the same place. It launched as 1099REPS for independent medical sales reps and now covers the wider 1099 economy, Washington included.
Frequently asked questions
How often do 1099 contractors pay taxes in Washington?
Quarterly. The IRS expects estimated payments in mid-April, mid-June, mid-September and mid-January, and charges an underpayment penalty for missing them even if you pay in full at filing. Washington has no state income tax, so the federal schedule is the whole calendar for most contractors there.
Do I need an LLC to work 1099 in Washington?
No. A sole proprietor can accept 1099 work under their own name and Social Security number, and many contractors start that way. An LLC adds liability separation and lets you elect S-corp taxation once profit is high enough for the payroll-tax saving to beat the extra filing cost. Washington sets its own formation fee and annual report requirements.
Is 1099 work better than a W-2 job in Washington?
It depends entirely on rate and stability. 1099 wins on control, deductibility and upside; W-2 wins on predictability, benefits and unemployment cover.
