The gap between your salary and your paycheck

The first real paycheck of a new job is a small shock. You negotiated a salary, did the division, and the number that arrived is meaningfully smaller. Nothing has gone wrong — four separate deductions sit between the two figures, and only one of them is the tax most people think about.

The four deductions

Take $85,000 a year, paid every two weeks — $3,269 gross per cheque, before anything comes out.

Federal income tax. The progressive one, charged in bands. On this salary in Texas it comes to about $10,160 a year.

Social Security — 6.2%. Charged on earnings up to an annual cap. About $5,270 here. Your employer pays the same again on your behalf, which you never see.

Medicare — 1.45%. No cap, so it applies to every dollar. About $1,233. Together with Social Security this is FICA, and it is the deduction most people cannot name.

State income tax. Anywhere from nothing to a substantial sum depending entirely on where you live.

Where you live changes the answer

The same $85,000 salary, two states:

• Texas — no state income tax. Take-home $68,338 a year, $2,628 per cheque.
• California — state tax of about $6,163. Take-home $62,175 a year, $2,391 per cheque.

A difference of $6,163 a year for identical work at an identical salary.

Before concluding that one state is simply better, note that states without an income tax generally recover the money elsewhere — property taxes, sales taxes, fees. A raw take-home comparison overstates the real difference in what you can afford, and housing costs usually swamp both.

The number that matters is the effective rate

On $85,000 in California, total federal and state income tax is about $16,323 — an effective rate of 19.2%, even though the top bracket touched is higher than that.

This is the marginal-versus-effective distinction again, and it is why “I'm in the 24% bracket” never means “I pay 24%”. Only the last slice of income pays the top rate.

The deduction that gives money back

Not every reduction to your cheque is a loss. Contributing 6% to a traditional 401(k) on this salary in Texas:

• Take-home falls from $2,628 to $2,475 per cheque — a reduction of $153.
• But $5,100 a year went into your retirement account, and federal tax fell by $1,122.

You moved $5,100 into savings at a cost of only $3,978 in take-home. The gap is the tax you no longer owe — and if your employer matches, the real return is far better still.

Note that FICA is charged on the full salary regardless. A 401(k) reduces income tax, never Social Security or Medicare, which is why the take-home reduction is not quite as small as the marginal rate alone implies.

Checking your own withholding

Withholding is an estimate your employer makes from your W-4, not a final bill. Get a large refund every year and you have lent the government money interest-free for twelve months. Owe a large amount every April and you have been under-withholding, with penalties possible.

Either way the fix is the same: update the W-4. A refund is not a bonus — it is your own money coming back late.

Estimates use 2026 federal brackets, a single filer taking the standard deduction, and a simplified flat state rate. Local city income taxes are not included.
