1099 Data Analyst Jobs in St. Louis, MO

Demand for data scientists and computer systems analysts in St. Louis

The St. Louis, MO-IL market supports 6,620 data scientists and computer systems analysts. That figure counts every employment arrangement, W-2 and 1099 alike — BLS does not split the two. Applying 1099WORK's estimate that roughly 25% of data scientists and computer systems analysts work on a 1099 basis puts the independent share near 1,655 people. Treat that as an order of magnitude, not a census. By headcount the market ranks 24th of the 364 metro areas where BLS publishes a figure for this occupation, putting it in the national top ten percent.

The location quotient is 1.11, within a rounding error of the national average. This is a representative market rather than a specialised one. The metro accounts for 58% of Missouri's total employment in the occupation. The metro's population is 2.8 million, roughly flat since 2020.

The discount to national pay matters when you quote: a rate anchored to a national benchmark will meet resistance here.

Data Analyst pay in St. Louis

The median data analyst in St. Louis earns $95,115 a year. That works out to $45.73 an hour at a standard 2,080-hour year. That is 10.8% below the national median of $106,599.

The spread matters more than the midpoint for anyone working 1099. The gap between the 10th and 90th percentile is $102,190, which is the range your negotiating position, client mix and specialisation actually move you across. Top-decile earners clear $151,958, against $49,768 at the bottom decile. These are W-2 and 1099 earnings combined, before any contractor adjusts for self-employment tax and unfunded benefits — which is what the next section is for.

Local, state and national side by side

St. Louis pays 5.7% above the Missouri median. Against the national median of $106,599 it sits 10.8% below. 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.

What to charge as a 1099 data analyst

A 1099 contract that pays the same headline number as a W-2 job is a pay cut. You pick up the employer's half of payroll tax, you stop being paid for holidays and time off, and health cover and retirement come out of your own revenue. Matching a $95,115 salary in St. Louis therefore takes about $126,869 in contractor gross — a multiplier of 1.33×.

Spread across a full 2,080-hour year that is $60.99 an hour. Nobody bills 2,080 hours: at a more realistic 80% utilisation, with the rest going to admin, invoicing and finding the next contract, the number you should quote is closer to $76.24.

The 1.33× multiplier assumes:

• 7.07% for the employer half of FICA, which self-employment tax shifts onto you
• 20 unpaid days a year — roughly ten holidays plus two weeks off
• 15% for health coverage and retirement you now fund yourself
• excludes business insurance, mileage, accounting fees and unbilled time

A rate card for St. Louis

The percentile spread above is more useful as a rate card than as a statistic. Each row below takes a point in the local wage distribution and applies the same 1.33× contractor multiplier, then divides across a realistic 80% billable year. Treat the middle row as your default and the bottom row as a floor you do not go under — not as a starting offer.

Nearby markets for data scientists and computer systems analysts

Contractors are not bound by a metro line the way a commuting employee is, and the neighbouring markets often price the same work differently. Within reach of St. Louis:

The tax consequence

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. At the St. Louis median that is roughly $3,360 a quarter in self-employment tax alone, before income tax. Missouri adds its own income tax and its own estimated-payment schedule on top.

Is this really 1099 work?

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 data scientists and computer systems analysts the usual flashpoints are set schedules, employer-supplied equipment and exclusivity clauses. Missouri also applies its own test, which can reach a different answer than the IRS does on identical facts.

1099WORK is a marketplace built for 1099 engagements specifically: companies post a defined scope, data scientists and computer systems analysts 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, St. Louis included.
