Traditional IRA: Rules, Tax Benefits & Contribution Limits

What Is a Traditional IRA?

A traditional IRA (Individual Retirement Account) is a tax-advantaged investment account designed for retirement savings. Its primary benefit is the potential tax deduction on contributions — the money you put in may reduce your taxable income for the year, lowering your current tax bill.

Unlike a Roth IRA where you pay taxes upfront and withdraw tax-free, a traditional IRA works on the pay later model. Contributions may be tax-deductible today, growth is tax-deferred while in the account, and withdrawals in retirement are taxed as ordinary income.

This "tax now vs tax later" distinction is the fundamental difference between traditional and Roth IRAs. The traditional IRA is most beneficial when you expect your tax rate to be lower in retirement than it is today, since you defer taxes to a time when you will pay a lower rate.

Traditional IRAs were created by the Employee Retirement Income Security Act (ERISA) in 1974. They remain one of the most widely used retirement accounts, with nearly $12 trillion in total assets held in IRAs in the United States.

How the Tax Deduction Works

The traditional IRA's tax deduction is its primary advantage, but not everyone qualifies for the full deduction.

If you do NOT have an employer retirement plan (401(k), 403(b), etc.), your traditional IRA contribution is fully deductible regardless of your income.

If you DO have an employer retirement plan, deductibility depends on your income:

Example of the tax benefit: If you are in the 24% tax bracket and contribute $7,000:

That $1,680 is money you keep today. However, you will eventually pay taxes on the entire withdrawal (contribution plus growth) in retirement. The question is whether the tax rate you pay then will be higher or lower than 24%.

Even if you cannot deduct your contribution (because of income limits), you can still make non-deductible contributions. The growth will be tax-deferred, though this is less attractive than a Roth IRA since Roth withdrawals are completely tax-free.

Contribution Limits for 2025

Traditional IRA contribution limits are identical to Roth IRA limits and shared between them:

Key rules:

• Limits are combined across all your IRAs (traditional + Roth). Contributing $4,000 to a traditional IRA leaves only $3,000 for a Roth IRA.
• You must have earned income at least equal to your contribution.
• Spousal IRA: A working spouse can fund a traditional IRA for a non-working spouse, effectively doubling the household contribution to $14,000.
• The contribution deadline is the tax filing deadline (typically April 15 of the following year).

Unlike the Roth IRA, there are no income limits for making traditional IRA contributions. Anyone with earned income can contribute. The income limits only affect whether the contribution is deductible.

Tax-Deferred Growth

Inside a traditional IRA, your investments grow tax-deferred. This means:

• No capital gains tax when you sell investments within the account
• No tax on dividends received within the account
• No tax on interest earned within the account
• Taxes are owed only when you withdraw money

Tax deferral allows your investments to compound without the drag of annual taxes. Here is the impact over 30 years on a $7,000 annual contribution earning 8%:

The tax-deferred account has $168,000 more before factoring in withdrawal taxes. Even after paying 22% tax on withdrawal, you would net approximately $618,000 — comparable to the taxable account but with the advantage of upfront deductions throughout the 30 years.

Required Minimum Distributions (RMDs)

Required Minimum Distributions (RMDs) are mandatory withdrawals from traditional IRAs that begin at age 73 (as of the SECURE 2.0 Act). The IRS requires these withdrawals to ensure that tax-deferred money is eventually taxed.

RMDs are calculated based on your account balance and your life expectancy factor from the IRS Uniform Lifetime Table:

For a $500,000 IRA at age 73:

Failure to take RMDs results in a penalty of 25% of the amount that should have been withdrawn (reduced from the previous 50% penalty). This drops to 10% if corrected within 2 years.

Key RMD facts:

• Your first RMD can be delayed until April 1 of the year after you turn 73
• All subsequent RMDs must be taken by December 31
• RMDs are taxed as ordinary income
• You can always withdraw more than the minimum
• Roth IRAs have no RMDs during the owner's lifetime

Traditional IRA vs Roth IRA

The traditional vs Roth decision is one of the most common questions in retirement planning. Here is a comprehensive comparison:

Choose the traditional IRA when:

• You are in a high tax bracket now and expect a lower one in retirement
• You need the immediate tax deduction to reduce this year's tax bill
• You do not qualify for Roth IRA contributions due to income limits (and the backdoor Roth is not suitable)
• You are close to retirement and want to defer taxes for a short period

Choose the Roth IRA when:

• You are in a low tax bracket now (young, early career)
• You expect tax rates to increase in the future
• You want tax-free income in retirement for planning flexibility
• You want to avoid RMDs
• You may need to access contributions before retirement

Consider both (tax diversification):

Many financial advisors recommend maintaining both traditional and Roth accounts. Having money in both gives you the ability to choose which account to withdraw from in retirement, optimizing your tax bill year by year. This is called tax diversification and provides maximum flexibility.

Withdrawal Rules and Penalties

Traditional IRA withdrawals follow specific rules depending on your age and circumstances.

Before age 59 1/2: Withdrawals are subject to ordinary income tax plus a 10% early withdrawal penalty. The penalty applies to the entire withdrawal since all money in a deductible traditional IRA is pre-tax.

Exceptions to the 10% penalty (but still taxed as income):

• First-time home purchase (up to $10,000)
• Qualified education expenses
• Unreimbursed medical expenses exceeding 7.5% of AGI
• Health insurance premiums while unemployed
• Disability
• Substantially equal periodic payments (SEPP/72(t))
• IRS levy
• Military reservist distributions

After age 59 1/2: Withdrawals are taxed as ordinary income but no penalty applies. You can withdraw any amount at any time.

After age 73: You must take RMDs. Withdrawals are still taxed as ordinary income.

Traditional IRA Investment Strategies

Like the Roth IRA, the traditional IRA is an account type, not an investment. You choose what to hold inside it.

Asset location strategy: Since traditional IRA withdrawals are taxed as ordinary income (up to 37%), it is tax-efficient to hold assets that would otherwise generate ordinary income:

This strategy places the most tax-inefficient assets in tax-deferred accounts and the most tax-efficient assets in taxable accounts, minimizing your overall tax burden.

Frequently Asked Questions

Can I convert my traditional IRA to a Roth IRA?

Yes. A Roth conversion moves money from a traditional IRA to a Roth IRA. You pay ordinary income tax on the converted amount in the year of conversion. There are no income limits or dollar limits on conversions. This can be beneficial if you expect higher tax rates in the future or want to eliminate RMDs on the converted funds. The strategy is most valuable during years when your income (and tax rate) is temporarily low.

What is the deadline to contribute to a traditional IRA?

You have until the tax filing deadline (typically April 15 of the following year) to make contributions for a given tax year. For the 2025 tax year, you can contribute through April 15, 2026. If you file an extension, the contribution deadline is still April 15 — extensions do not extend the IRA contribution deadline.

Can I contribute to a traditional IRA if I have a 401(k)?

Yes. You can always contribute to a traditional IRA regardless of whether you have a 401(k). However, having an employer plan may limit your ability to deduct the contribution. If your income exceeds the deduction phase-out range, your contribution is non-deductible. You still get tax-deferred growth, but a Roth IRA is typically the better choice for non-deductible contributions.

What happens to my traditional IRA when I die?

Your traditional IRA passes to your designated beneficiaries. A surviving spouse can roll the inherited IRA into their own IRA and continue tax-deferred growth. Non-spousal beneficiaries must withdraw the entire balance within 10 years of inheritance (SECURE Act rules), and withdrawals are taxed as ordinary income.

Can I have both a traditional IRA and a Roth IRA?

Absolutely. You can contribute to both in the same year as long as your total contributions across all IRAs do not exceed the annual limit ($7,000 in 2025). Many advisors recommend splitting contributions between both for tax diversification, giving you flexibility to manage your tax bracket in retirement.
