For example, if you have $60,000 in taxable income and contribute $5,000 to a Roth IRA or Roth 401(k), you still have $60,000 in taxable income, and your take-home pay is reduced by $5,000.
With a traditional 401(k) or traditional IRA, the same $60,000 in taxable income and $5,000 contribution reduces your taxable income to $55,000. If you're in the 22% tax bracket as a single filer, that will save you $1,100 in taxes and reduce your take-home pay by only $3,900.
It is important to note that while a Roth IRA is an individual account that doesn't receive employer contributions, employers can make matching contributions to a Roth 401(k).
