Engaging a 1099 software developer in Washington means competing for people inside a pool of 91,470 software developers, against a median wage of $166,910. This page works through what that means for an independent contractor: the pay spread, the rate you need to quote to come out ahead of payroll, and the tax and classification rules that apply in Washington.
Every figure is from the Bureau of Labor Statistics' Occupational Employment and Wage Statistics programme (May 2024) or the Census Bureau's 2024 population estimates. Where BLS suppressed a number for this market, the sentence that would have used it is simply absent — nothing here is filled in with an estimate unless it is labelled as one.
What Washington looks like for software developers
Washington employs 91,470 software developers. That figure counts every employment arrangement, W-2 and 1099 alike — BLS does not split the two. Applying 1099WORK's estimate that roughly 30% of software developers work on a 1099 basis puts the independent share near 27,441 people. Treat that as an order of magnitude, not a census.
Concentration is the more interesting number. The location quotient is 2.41, meaning software developers make up a share of local employment 141% larger than they do nationally. Demand here is structural, not incidental.
A concentration that far above the national average means employers here are not incidental buyers of the skill — they are the reason the cluster exists, and they buy accordingly. Local pay above the national line is worth holding out for — it is the difference between a national rate and what this market will actually bear. One local factor never shows up in wage data at all: Washington levies no state income tax, so a given gross goes further here than the same gross in a taxed state.
Budgeting for a 1099 software developer
The honest comparison is not salary against contract rate — it is fully loaded cost against contract rate. A W-2 software developer in Washington at the $166,910 median costs roughly $206,630 once you add employer payroll tax and a conservative benefits load. A contractor quoting $222,633 for the same output is close to cost-neutral, and you carry none of the unemployment insurance, benefits administration or severance exposure.
Where 1099 genuinely wins is variable demand. You pay for the engagement, not the calendar, and you can scale a territory or a project up and down without a headcount decision. Where it loses is control: the moment you need to set someone's hours, supply their tools and forbid other clients, you are describing an employee, and Washington's agencies will say so.
Costs a 1099 engagement avoids that payroll does not:
- Employer FICA at 7.65% of wages
- Federal and state unemployment insurance
- Workers' compensation premiums in most classifications
- Health, dental and retirement contributions
- Paid leave, holidays and severance exposure
The classification caveat
Labelling an engagement 1099 does not make it 1099 — the IRS weighs who controls the work, who supplies the tools and who carries the risk. For software developers the usual flashpoints are set schedules, employer-supplied equipment and exclusivity clauses. Washington also applies its own test, which can reach a different answer than the IRS does on identical facts.

Benchmarking Washington
Against the national median of $133,080 it sits 25.4% above. The location quotient column is the one worth reading twice: it measures how concentrated the occupation is relative to the national average, and it moves independently of pay.
| Area | Employed | Median annual | 90th percentile | Location quotient |

| Washington | 91,470 | $166,910 | — | 2.41 |

Where to look next
1099WORK is a marketplace built for 1099 engagements specifically: companies post a defined scope, software developers 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.
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. As a rule of thumb, a 1099 engagement needs to pay about 1.33× the equivalent salary before it is genuinely better money.
How many software developers work in Washington?
BLS counts 91,470 software developers in Washington. 1099WORK estimates roughly 27,441 of them work on a 1099 basis, though BLS does not publish that split.
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.
What are the risks of hiring a 1099 software developer in Washington?
Misclassification is the main one, and it is assessed against the hiring company. If you set the schedule, supply the equipment and forbid other clients, agencies will treat the engagement as employment regardless of what the contract says, and Washington applies its own test separately from the IRS. A written scope of work, a defined deliverable and a contractor who serves other clients are the practical defences.
How much does a 1099 software developer make in Washington?
The median software developer in Washington earns $166,910 a year according to BLS OEWS data for May 2024, covering W-2 and 1099 workers together. Working 1099, you would need roughly $222,633 in gross billings to match that median after self-employment tax and unfunded benefits.
