The highest-paying freelance jobs of 2020 where you can earn $90,000 or more

As some labor advocates worry that the lowest-paid gig workers are being exploited by companies, freelance workers on the other end of the income spectrum are seeing booming demand for their services and even a boost to their earning power.

A list of the highest-paying freelance jobs, created for CNBC.com by the global freelancing platform Upwork, shows dozens of jobs in which freelancers can earn $90,000 per year — or more.

"People should look at this list and think a little differently about the freelance economy," says Adam Ozimek, Upwork's chief economist. "There's too much focus on a narrow corner of the freelance economy and lower-skilled workers. This report shows how diverse this segment of the economy is and how much of it is high-skilled work."

Nearly 60 million Americans freelanced in 2019, either full-time or part-time, representing more than a third of the American workforce, according to a separate study by Upwork and Freelancers Union. Skilled services were the most common type of freelance work.

A study by MBO partners found that more than half of full-time independent workers say that they feel more financially secure in their current roles than in traditional jobs. That report found that there are more than 15 million full-time freelancers, with 1 in 5 earning more than $100,000 per year.

In the absence of a severe recession, experts say that 2020 holds plenty of opportunity for those freelance workers with professional skills.

"High-end professionals are going to have a great year next year, whether they're freelance or not" said Steve King, a partner at Emergent Research, a company in Lafayette, California, that studies the independent workforce. "The job market is just so tight, and those skills are really hard to find."

Here's a look at the highest-paying freelance jobs that should be in great demand in 2020, according to Upwork. The annual income is based on a 40-hour workweek, 50 weeks a year.

*Upwork's methodology: In order to create a list of the top-paying freelance jobs, we used data sourced from the Upwork.com database. We first pulled data of freelance jobs on the site starting Jan. 1, 2018, to Dec. 1, 2019. We then limited the analysis to categories of work that had more than 1,000 completed jobs and total freelancer earnings of over $1 million. Within that we ranked the top 25 jobs based on the highest median hourly earnings.
