Just ran my $100K salary through a tax calculator and honestly? The results are wild depending on where you live. I thought federal taxes were the main hit, but FICA and state taxes add up way faster than I expected.

So here's what I found about taxes on 100k salary situations across the US. If you're in states like Texas, Florida, Nevada, Washington, or Wyoming with no state income tax, you're looking at keeping around $78,736 after everything. That's federal plus FICA eating about $21,264. But if you're in Oregon? You're down to $70,540 after taxes. Hawaii's also brutal at $72,579 take-home.

The middle ground states are interesting too. Most places fall somewhere between $73K-$76K after taxes on 100k salary. Like Colorado keeps you at $74,996, New Jersey at $74,490, that range. It's actually crazy how much state tax rates matter when you're looking at real numbers.

What surprised me most is the FICA component - that's locked in federally regardless of state, so you can't escape it. But yeah, if you're making six figures, definitely check where you're filing because the difference between no state tax and high state tax states is literally thousands per year. The taxes on 100k salary calculation really shows why people talk about tax optimization.
