Thanks for the reply -- in this context, someone is still going to have to handle the various state charges for L&I/B&O taxes, etc, as well as unemployment insurance, etc. That compliance burden presumably still lands on the sole-proprietor.
I'll dig into sole-proprietorship now to see if it can meet the company's checklist items for 'incognito206 is clearly not an employee'.
I second the recommendation above. You shouldn't be paying UI or workers comp AFAIK, but yes to B&O tax and probably licensing fees both to Washington and Seattle. I'd recommend having a good contract in place.
When I was getting started I think I adapted one from Nolo, and that was fine for my needs. You could ask them (the client) to supply one and adjust it as you like.
