I think I understand from the other comments. I never considered that it is technically an expense to withhold the income taxes of employees and then pay it to the IRS.
I'm going to go out on a limb and suggest that number is not actually employee income tax, even though the report seems to suggest the same. Employee income tax is an expense of the employee, not the employer. If it is income tax withholding, it's way too small for $150k+ of employee comp, which is another reason I don't think it's that. Instead, I expect this tax line item to be primarily the employer share of FICA tax, which is typically considered a payroll tax instead of an income tax.
