Hi @mskatrose , thanks for the question! As is so often the case, the answer is, "It depends." š Since Illinois and South Carolina are not adjacent, is it safe to assume that you are working remotely from South Carolina? If so, then you are likely not liable for Illinois tax. Illinois has not stated that telecommuting non-residents are subject to tax because their employer is in Illinois. As long as you have not spent more than 30 days in Illinois, then you should not be subject to their state tax.
Hope this helps!
