What a Traditional IRA Means in Plain English

A traditional IRA is a retirement account built around a simple premise: defer your taxes until retirement. You may get a tax deduction on contributions now, your money grows without annual tax drag, and you pay income taxes on withdrawals later. The government essentially gives you an interest-free loan equal to the taxes you would have paid on your contributions, and you invest that money for decades.

“IRA” stands for Individual Retirement Account — you open it yourself at any brokerage, not through an employer. You choose what to invest in, just like a Roth IRA. The key difference is timing: traditional means pay taxes later, Roth means pay taxes now.

The bet with a traditional IRA is that your tax rate in retirement will be lower than it is today. If you’re earning $120,000 now in the 22% bracket but expect to live on $60,000 in retirement in the 12% bracket, the traditional IRA is the mathematically superior choice. Pay 12% then instead of 22% now — that’s a meaningful advantage.

How a Traditional IRA Works

The 2024 contribution limits are the same as the Roth IRA: $7,000 per year, $8,000 if you’re 50 or older. Unlike a Roth, there’s no income limit that prevents contributions — anyone can put money in a traditional IRA regardless of what they earn.

The catch is deductibility. If you (or your spouse) have access to a workplace retirement plan like a 401(k), your ability to deduct traditional IRA contributions phases out at higher incomes. For single filers in 2024: full deduction below $77,000, partial deduction between $77,000 and $87,000, no deduction above $87,000. For married filing jointly: full deduction below $123,000, phase-out through $143,000. If you’re above these limits, you can still contribute — you just don’t get the tax deduction.

There’s a hard deadline the IRS imposes: Required Minimum Distributions, or RMDs. Starting at age 73, the government requires you to withdraw a minimum amount each year, calculated based on your account balance and life expectancy. This ensures you eventually pay taxes on money that was deferred. Fail to take your RMD and the IRS charges a 25% penalty on the amount you should have withdrawn.

Why a Traditional IRA Matters to You

The traditional IRA’s power is the upfront deduction, if you qualify. Invest $7,000 and reduce your taxable income by $7,000 — in a 22% bracket, that’s $1,540 back in your pocket immediately (or really, just not taken from your paycheck). That $1,540 can be reinvested, creating a compounding advantage from day one.

For people who are high earners now and expect to be in a lower bracket in retirement — many people, actually, since most retirement income is lower than peak working income — a traditional IRA often wins the head-to-head comparison with Roth. The deferred tax compound growth plus the lower withdrawal tax rate can add up to significantly more after-tax wealth.

The RMDs are worth planning around. If you accumulate substantial traditional IRA assets, mandatory distributions at 73 might push you into a higher bracket than you’d like. Some people do Roth conversions in early retirement (after stopping work but before RMDs kick in) to shift money from traditional to Roth, paying taxes at a lower rate.

Quick Example

You earn $95,000 as a single filer in 2024 and have a 401(k) at work. Your income is above the $87,000 limit, so your traditional IRA contribution isn’t deductible. You contribute $7,000 anyway — a non-deductible contribution. The money still grows tax-deferred, meaning you won’t owe taxes on gains each year. When you withdraw, you’ll pay taxes on the growth but not the original $7,000 (you already paid tax on that).

Now compare a colleague earning $72,000 — below the phase-out threshold. Same $7,000 contribution, but they deduct it, reducing their taxable income to $65,000 and saving about $1,540 in taxes this year. Same account, very different tax outcome.

Common Misconceptions

  • “Anyone can deduct a traditional IRA contribution.” The deductibility rules are income-based and depend on whether you have a workplace retirement plan. Many people contribute to traditional IRAs expecting a deduction they don’t qualify for. Check the income limits before assuming you’ll get the tax break.
  • “I never have to withdraw from my IRA.” Required Minimum Distributions start at 73 and are mandatory. Unlike a Roth IRA, which has no RMDs during the original owner’s lifetime, a traditional IRA will eventually force taxable withdrawals. This is especially relevant for estate planning — large traditional IRA balances can create significant tax burdens for heirs.
