W-2 or 1099 as a therapist in Washington: the arithmetic nobody publishes

A 1099 therapist in Washington pays the full 15.3 percent self-employment tax, both halves of Social Security and Medicare, where a W-2 employee pays 7.65 percent and the employer pays the other 7.65. On top of that, a 1099 clinician buys their own malpractice coverage, has no workers' compensation coverage through the practice, cannot draw unemployment from that engagement, and receives no employer contribution toward Washington's Paid Family and Medical Leave premium. A 1099 arrangement has to pay meaningfully more per session to break even, and the way to compare two offers is total annual compensation divided by the sessions required to earn it, rather than the percentage.

That is the whole answer. The rest of this page is the arithmetic, the Washington-specific figures for 2026, and the tests that determine whether a role is legally allowed to be 1099 in the first place.

What the employer pays for a W-2 employee in Washington, 2026

These are the costs a 1099 clinician absorbs personally. Every figure is cited at the bottom of the page.

• Social Security. 6.2 percent each on wages up to $184,500. Paid by employer and employee, equally.

• Medicare. 1.45 percent each, no wage cap. Paid by employer and employee, equally.

• Federal unemployment, FUTA. 6.0 percent on the first $7,000 of wages, net 0.6 percent at the full state credit. Employer only, no employee share.

• Washington unemployment insurance. Taxable wage base $78,200, combined rate capped at 6.0 percent. Employer only. RCW 50.24.010 makes deducting it from wages unlawful.

• Paid Family and Medical Leave. 1.13 percent of gross wages up to $184,500. Split 28.57 percent employer, 71.43 percent employee. Employers under 50 employees are not required to pay the employer share but must still collect the employee share.

• L&I Accident Fund. Rate varies by risk class. 2026 average increase 4.9 percent. Employer only.

• L&I Medical Aid, Stay at Work, and Supplemental Pension Funds. Rate varies by risk class. Split equally, and an employer may choose to absorb the employee half.

• WA Cares Fund. 0.58 percent of gross wages, no cap. Employee only.

The line most people get wrong is L&I. Three of the four Washington workers' compensation funds are split equally with the employee. Only the Accident Fund is employer-only. Any comparison that treats all of L&I as an employer cost overstates the employer's side.

A W-2 clinician earning $85,000 has roughly $6,502 in employer FICA paid on their behalf, plus unemployment, plus the employer share of Paid Leave, plus the employer portion of L&I. A 1099 clinician earning the same $85,000 in net profit pays that FICA amount themselves, as part of the 15.3 percent self-employment tax, and pays it in quarterly estimated installments out of cash flow.

What a 1099 clinician buys that a W-2 clinician does not

Professional liability coverage. Published carrier rates for individual professional liability at $1 million per occurrence and $3 million aggregate run roughly $200 to $800 a year for a full-time clinician, with the low end reflecting early claims-made years. One caveat worth stating: no carrier publishes a Washington-specific rate table for LMFT, LMHC, or LICSW credentials. The Washington figures available are from a psychologist program, and the rate schedule carries no effective date. If you want a real number for your own credential, run a quote through CPH, Berxi, or HPSO with your ZIP code. Do not rely on a published range, including this one.

Health insurance, at unsubsidized or partly subsidized cost. Washington's 2026 average benchmark premium, the second lowest cost silver plan for a 40-year-old, weighted by county plan selections, is $612 a month. Washington's Office of the Insurance Commissioner approved an average 21 percent rate increase for the 2026 individual Exchange market. What you pay depends on your county, your age, your household income, and whether the Enhanced Premium Tax Credits survive, and in Pierce County the cheapest gold-tier option for a 40-year-old was $426 a month as of mid-2026. What that means for the comparison is that a benefits-eligible W-2 role removes a variable expense of this size from your household budget, and the size of that variable is why it matters more than most candidates weight it.

Retirement contributions, paid time off, and continuing education, where an employer offers them. These are the items candidates most often value at zero in a comparison because they are hard to price. Price them. An employer 401(k) match is deferred compensation, and CE reimbursement against a licensure requirement you have to meet anyway is a direct dollar-for-dollar cost avoided.

Every unbilled hour. A 1099 clinician who handles their own scheduling, verification, claims, denials, appeals and no-show follow-up is working those hours at zero dollars. This is the largest cost in the comparison and the one nobody quantifies, because it does not appear on either side of a fee split.

On Washington income tax, stated precisely

Washington has no state income tax on wages, and none is scheduled through 2027. That statement needs a date on it now, because Engrossed Substitute Senate Bill 6346, signed 30 March 2026, establishes a 9.9 percent tax on household income above $1 million, effective for tax years beginning 1 January 2028. Initiative 645, which would repeal it, qualified for the November 2026 ballot, and a constitutional challenge is anticipated. For a clinician comparing two 2026 offers, this changes nothing. For anyone modelling several years out, it is worth knowing the landscape moved.

Whether a role is legally allowed to be 1099

This is the part of the comparison that is not a preference. Classification is determined by the working relationship, not by what the contract calls it, and Washington applies tests that are stricter than the federal ones.

Federally, the operative test under the Fair Labor Standards Act is the economic reality test. The picture is unusually unsettled right now. The Department of Labor's 2024 rule remains published at 29 CFR Part 795 and still governs private litigation, while the Department itself stopped applying it in enforcement on 1 May 2025 under Field Assistance Bulletin 2025-1 and reverted to the pre-2024 framework. A replacement rule was proposed on 26 February 2026, built around control and opportunity for profit or loss as two core factors, and as of 7 August 2026 it has not been finalized.

The IRS applies a common-law test across three categories of evidence: behavioral control over what the worker does and how, financial control over the business aspects of the job, and the type of relationship, which takes in written contracts, employee-type benefits, permanency, and whether the work is a key aspect of the business. No single factor decides it.

Washington's own tests are the ones most likely to bite, and they are materially stricter. For unemployment insurance purposes, RCW 50.04.140 offers two routes. One is an ABC test. The other is a six-part test in which all six parts must be met, and three of those six have no federal counterpart at all: the worker files a schedule of expenses with the IRS, has established accounts with the Department of Revenue and other required state agencies including a UBI number, and maintains a separate set of books and records. L&I applies a parallel six-part test under RCW 51.08.180, 51.08.181 and 51.08.195, seven parts in construction.

The practical consequence is that a clinician can be a defensible 1099 contractor for federal purposes and still be a covered worker for Washington's Employment Security Department and L&I. If a role directs your schedule, assigns your caseload, requires your documentation in the practice's system, and holds you out to clients as part of the practice, the tests are worth reading before you sign. Talk to your own tax or employment advisor. This page is not advice about your situation.

The fee split question, and why the number you have heard is not real

Percentages circulate in Washington. A 60/40, a 70/30, a claim about what the market pays. They get repeated in coaching content, accounting-firm marketing and practice blogs, and they get quoted back in interviews as though someone had measured them.

Nobody has measured them. Checked on 7 August 2026:

• The Heard 2026 Financial State of Private Practice Report, roughly 2,000 respondents and the most-cited financial survey in this field, publishes median practice revenue and profit. It contains no fee split data, no percentage of collections, and no Washington breakout. Its top five states are California, Texas, New York, Colorado and Florida.

• The SimplePractice 2026 State of Private Practice Report, drawing on 245,000 clinicians and a survey of more than 2,200, publishes reimbursement mix, admin burden and telehealth patterns. No fee split percentages.

• The MGMA 2026 Provider Compensation Data Report publishes median compensation and work RVUs by specialty. No compensation-to-collections ratio on the public record.

• The American Counseling Association's Counseling Workforce Report publishes national average salary, $71,000 full-time. No practice structure metrics, no state stratification.

• The Washington Health Care Authority publishes payer reimbursement and total cost of care benchmarks. Those measure what insurers pay practices, not what practices pay clinicians.

• The Washington Mental Health Counselors Association publishes no compensation survey.

Every source offering a split percentage was vendor content, accounting-firm marketing, or practice-coaching material with no disclosed sample, no methodology, and in the most-quoted case no year on the post.

So when a practice tells you their split is competitive, ask competitive against what. There is no answer to that question, which means the percentage is not a comparison tool. What you can compare is total annual compensation, including the employer-paid items in the list above and the dollar value of benefits, divided by the number of sessions you have to deliver to earn it. Two offers with identical percentages can differ by a wide margin on that figure, and it is the figure that describes your year.

How Northwest Relationships is structured

Every clinician at Northwest Relationships is a W-2 employee. That was a deliberate choice in a field where 1099 arrangements are common, and it costs the practice the employer share of every line in the list above.

Session expectations run on a quarterly tier the clinician chooses rather than a weekly quota, which is how the practice handles the reality that a caseload is not a constant. Billing, scheduling, insurance verification, claims and denials are handled by the administrative team, which is the unbilled work that otherwise lands on the clinician. Supervision toward licensure is provided in-house rather than purchased, and for associates that is the single largest transfer of value in the arrangement, because Washington requires at least 200 supervision hours for LMFT licensure with at least 100 of them one to one, and Washington supervisors selling supervision privately publish rates from $100 to $200 an hour.

The full structure, including the tier numbers and what benefits cover, is on the careers page.
