When someone in the US says they make $100,000 per year, that is usually exclusive of any tax paid by the company. It is also exclusive of other benefits paid, with health insurance commonly being $10-20k paid by the company, if provided. The employee is responsible for their own income tax.

There’s confusion because in the gig/entrepreneur/consultant world, people will say they “make” $200,000 in business income. But then they bear taxes and benefits out of that amount. So you may “make” more, but do worse than someone who is an employee of a bigger company. That is why it takes a substantial increase in income in the US to justify leaving a stable employer.
