One significant advantage of investing pre-tax dollars in a retirement account, such as a 401(k) or traditional IRA, is the immediate tax benefit. Contributions made to these accounts are deducted from your taxable income for the year, which can effectively lower your tax bill. For example, if you earn $50,000 and contribute $5,000 to a traditional IRA, your taxable income would be reduced to $45,000 for that tax year.
Additionally, the funds in these accounts grow tax-deferred, meaning you won't pay any taxes on the investment gains until you withdraw the money during retirement. This can lead to greater accumulation of wealth over time, as your investments can grow without the drag of annual taxes on capital gains or interest earned. Ultimately, this can allow for more significant growth in your retirement savings.
