On a $40,000 salary, a single filer with a 5% 401(k) and $100 a paycheck for health insurance takes home about $30,471 a year in a state with no income tax, and about $28,749 in Massachusetts. The difference is entirely state tax; federal tax and payroll tax are the same everywhere.

Where the money goes in Texas (no state income tax)
Your federal taxable income is $19,300 after the $16,100 standard deduction and $4,600 of pre-tax deductions. The top federal bracket you reach is 12%, but your average federal rate is only 5.2% ($2,068). Social Security (6.2%) and Medicare (1.45%) take $2,861 together. Both apply to every dollar of wages at this level.

Filing status changes the federal bill
| Filing status | Federal tax | Take-home | Per paycheck |
|---|---|---|---|
| Single | $2,068 | $30,471 | $1,171.96 |
| Married filing jointly (one earner) | $320 | $32,219 | $1,239.19 |

How much the 401(k) percentage matters
| 401(k) rate | Contribution | Federal tax | Take-home | Per paycheck |
|---|---|---|---|---|
| 0% | $0 | $2,308 | $32,231 | $1,239.65 |
| 5% | $2,000 | $2,068 | $30,471 | $1,171.96 |
| 10% | $4,000 | $1,828 | $28,711 | $1,104.27 |
| 15% | $6,000 | $1,588 | $26,951 | $1,036.57 |
Every extra percentage point of 401(k) costs less than a full point of take-home pay, because the contribution also lowers federal tax. At this salary, the next $1,000 of raise keeps $760 after tax and the 5% 401(k) share.

Questions people ask
Is this what my employer will withhold?
Not exactly. Withholding follows your W-4 and pay schedule. These figures are the annual tax on the income, split into 26 equal paychecks, so your actual withholding can run a little higher or lower until you file.
Why is take-home lower than $40,000 minus tax?
The 401(k) contribution and health premium also come out of each paycheck. Here that is $4,600 a year.
