What about payroll taxes? In most places, your employer pays additional tax on top of your pre-tax salary.

Apart from the withholding of income tax (which I was already counting), I think they only pay social security (23.75%).

Considering that many professional programmers with a college degree in Software Engineering make ~$1300/m (net), the remaining $2700 is plenty to cover all taxes and expenses for both parties.
