A $1,000 tax deduction is worth $220 to someone in the 22% band
· 4 min read
A $1,000 tax deduction does not take $1,000 off your tax bill. It takes $1,000 off the income that is taxed. What that saves depends on the rate your last dollars are taxed at. For a single person earning $80,000, it is $220.
The same deduction at every federal rate
Federal income tax is charged in bands, and a deduction comes off the top band your income reaches. So its value is the deduction multiplied by that band’s rate. These are the 2026 federal rates:
The same $1,000 is worth more than three times as much to someone in the highest band as to someone in the lowest. Nothing about the deduction changed.
Which band is yours
It is set by your taxable income, which is your income less the standard deduction and anything else that comes off first. For a single filer taking the standard deduction of $16,100 in 2026:
- On $40,000: the 12% band, so $1,000 saves $120.
- On $80,000: the 22% band, so $1,000 saves $220.
- On $150,000: the 24% band, so $1,000 saves $240.
The take-home pay calculator shows the band your own salary reaches. Enter a pre-tax deduction there and the federal tax line falls by the amount described here.
When a deduction is worth nothing
Many deductions only count if you itemize, which means giving up the standard deduction and listing your own instead. If your itemized total is smaller than the standard deduction, those deductions change nothing. Some deductions are taken whether you itemize or not. Which kind yours is, and whether you qualify for it, is a question for the IRS instructions or a tax professional.
What this leaves out
- State and local income tax. A deduction may save state tax too, at your state’s rate. That is not counted here.
- Social Security and Medicare. Most deductions do not reduce these. Some pre-tax payroll items do.
- A deduction that crosses a band. If it carries your taxable income down into a lower band, part of it is worth the lower rate.
- Other filing statuses. The examples are for a single filer. The bands start at different incomes for other statuses.
