State tax, where selected, uses that state's own 2026 brackets or flat rate; New York additionally stacks New York City's local income tax on top. Leaving "No state selected" shows the federal-only baseline. Does not account for 401(k) contributions, HSA contributions, itemized deductions, or filing statuses other than single. For precise figures, consult the IRS or a tax professional.

Permanent median
$170,000
$127,461 take-home
Contract median
$103/hour
≈ $197,760 gross a year
At a median $103/hour, contract work grosses about $197,760 a year over 1,920 billable hours (240 days), 16% more than the $170,000 permanent median. That premium has to pay for what an employer would otherwise cover: paid holiday and sick days, pension contributions, and the gaps between contracts.
Contract and permanent benchmarks come from separate samples, so treat the gap as a guide rather than a like-for-like quote. See AI Infrastructure Engineer contract rates and contractor take-home →
