A traditional IRA lets you put in pre-tax dollars, which lowers your taxable income in the year you contribute

Yes, a traditional IRA is funded with pre-tax money. When you contribute to a traditional IRA, that money comes out before federal income tax is calculated on your earnings. If you earn $50,000 and contribute $7,000 to a traditional IRA, your taxable income for that year is $43,000 instead.

This tax break is the main reason people choose traditional IRAs over other savings accounts. You get an immediate reduction in what you owe the IRS that year. The catch is that when you withdraw the money in retirement, you pay income tax on it then—both on what you put in and on all the growth it earned.

A Roth IRA works the opposite way: you contribute after-tax dollars (money you already paid tax on), but withdrawals in retirement are tax-free. The choice between the two depends on whether you think your tax rate will be higher now or in retirement.

Key Takeaways

  • Traditional IRA contributions reduce your taxable income in the year you make them, lowering what you owe the IRS that tax season.
  • You pay income tax on traditional IRA withdrawals during retirement, including both your contributions and the earnings they generated.
  • Roth IRAs work in reverse: you contribute after-tax money but pay no tax on withdrawals in retirement.
  • The IRS limits how much you can contribute each year, and the limit changes periodically based on inflation.
  • Not everyone can deduct a traditional IRA contribution if they have a workplace retirement plan and earn above a certain income threshold.

When the pre-tax deduction phases out or disappears

The pre-tax benefit of a traditional IRA is not automatic for everyone. If you have access to a workplace retirement plan—like a 401(k) or 403(b)—and your income is above a certain threshold, the IRS phases out or eliminates your deduction.

The income limits change each year and depend on your filing status. A single filer with a workplace plan hits the phase-out range at one income level; a married couple filing jointly hits it at a higher level. If your income is above the phase-out range, you cannot deduct the contribution at all, even though you can still put money into the traditional IRA.

This is why some people with high incomes and workplace plans choose a Roth IRA instead: they can still contribute, and the money grows tax-free. Others use a strategy called a "backdoor Roth," which involves contributing to a traditional IRA and then converting it to a Roth, though this has its own rules and tax consequences.

How the pre-tax deduction works on your tax return

When you file your federal income tax return, you report your traditional IRA contribution on Form 1040 or Form 1040-SR. The contribution reduces your adjusted gross income (AGI), which is the number the IRS uses to calculate your tax bracket and determine what you owe.

You do not need to itemize deductions to claim a traditional IRA contribution. It is a "above-the-line" deduction, meaning it lowers your income before the standard deduction is applied. This makes it valuable even if you take the standard deduction instead of itemizing.

Your IRA custodian (the bank or brokerage holding your account) will send you a Form 5498 in January showing what you contributed the previous year. You use this form to fill out your tax return correctly.

The difference between pre-tax contributions and tax-deferred growth

Pre-tax contributions and tax-deferred growth are related but different. A pre-tax contribution means the money you put in reduces your taxable income that year. Tax-deferred growth means the earnings inside the account—interest, dividends, capital gains—are not taxed each year as they happen.

In a traditional IRA, both happen together. You get the deduction upfront, and then the money grows without annual tax bills. In a Roth IRA, contributions are after-tax, but the growth is also tax-deferred and tax-free at withdrawal. In a regular taxable brokerage account, you get neither benefit: you pay tax on contributions (because they are after-tax dollars) and you pay tax on growth each year.

Required withdrawals and taxes in retirement

The pre-tax advantage of a traditional IRA comes with a requirement: you must start taking withdrawals at age 73 (as of 2023; this age has been rising gradually). These are called required minimum distributions, or RMDs. The IRS calculates how much you must withdraw each year based on your age and account balance.

Every dollar you withdraw from a traditional IRA is taxed as ordinary income. If you withdraw $40,000 in a year, that $40,000 is added to your other income for tax purposes. This can push you into a higher tax bracket or trigger other tax consequences, like higher Medicare premiums or taxation of Social Security benefits.

This is why the pre-tax benefit is really a tax delay, not a tax elimination. You save money on taxes now, but you will owe it later. Whether that is a good trade depends on whether you expect to be in a lower tax bracket in retirement than you are now.

Contribution limits and catch-up contributions

The IRS sets an annual limit on how much you can contribute to a traditional IRA. This limit applies to the total of all your IRAs combined—you cannot contribute the limit to multiple IRAs and multiply the benefit. The limit changes most years based on inflation.

If you are age 50 or older, you can make an additional catch-up contribution, which is a smaller amount on top of the regular limit. This is designed to help people who started saving later in life. The catch-up amount also changes with inflation.

You can only contribute up to the limit if you have earned income that year. If you are retired and have no wages, you cannot contribute to an IRA, even if you have money in the bank.

Pre-tax IRAs versus employer plans

A traditional IRA is not the only way to save with pre-tax money. Employer retirement plans like 401(k)s and 403(b)s also use pre-tax contributions. The main differences are contribution limits (much higher for employer plans) and investment options (employer plans offer fewer choices, but IRAs let you invest in almost anything).

If your employer offers a 401(k) with a match, most financial advisors recommend contributing enough to get the full match before maxing out an IRA. The match is assistance programs. After that, an IRA often makes sense because of the wider investment choices and lower fees.

Frequently Asked Questions

Can I contribute to a traditional IRA if I do not have a job?

No. You must have earned income to contribute to any IRA. Earned income means wages, salary, self-employment income, or other compensation for work. Investment income, Social Security, pensions, and unemployment benefits do not count. If you are married and your spouse has earned income, you may be able to contribute to a spousal IRA in your name.

What happens if I contribute to a traditional IRA but cannot deduct it?

You can still contribute, but you will not get the tax break that year. You will owe tax on the contribution when you withdraw it in retirement, even though you already paid tax on it going in. This is called a non-deductible contribution. You must file Form 8606 with your tax return to track this, or you will pay tax twice on the same money.

If I withdraw money from my traditional IRA before retirement, do I pay tax on it?

Yes. Withdrawals before age 59½ are taxed as ordinary income, and you also owe a 10% early withdrawal penalty on top of the income tax—unless an exception applies. Exceptions include disability, medical expenses above a threshold, and a few others. The penalty is in addition to the tax, not instead of it.

Does a traditional IRA lower my taxes if I am self-employed?

Yes, but self-employed people have additional options. You can contribute to a traditional IRA like anyone else, but you can also set up a SEP-IRA or Solo 401(k), which allow much larger pre-tax contributions based on your self-employment income. A tax professional can help you choose which makes sense for your situation.
