Is a Traditional IRA Tax-Deferred? Deductions, Growth, and RMDs

Yes, a Traditional IRA is tax-deferred. That means the federal government lets you postpone income tax on the money in three connected ways: qualifying contributions come off your taxable income the year you make them, investment gains and dividends inside the account are not taxed year to year, and you pay ordinary income tax only when you take the money out.¹ Deferred is not the same as forgiven. The IRS eventually collects, and several rules control exactly how much and when.

The Up-Front Deduction

Tax deferral begins with the contribution. Federal law lets you subtract qualifying contributions from your gross income for that tax year, which directly lowers the amount the IRS can tax.² Earn $60,000 and contribute the full $7,500 allowed for 2026, and the IRS treats your taxable income as $52,500.

For 2026, the contribution ceiling is $7,500, up from $7,000 in 2025. If you are 50 or older at any point during the year, you can add $1,100 in catch-up contributions for a total of $8,600.³ The limit is a household-per-person cap that covers your Traditional and Roth IRAs combined, not each account separately. You have until the federal tax-filing deadline of the following April to make a contribution that counts for the prior tax year.

There is no longer any age cap. Before 2020 you could not contribute to a Traditional IRA after 70½, but that restriction was removed. Anyone with taxable compensation, or a spouse whose compensation covers the contribution on a joint return, can now contribute at any age.⁴

When the Deduction Phases Out

Whether the contribution is actually deductible turns on two things: your Modified Adjusted Gross Income (MAGI) and whether you or your spouse are covered by a workplace retirement plan. If neither of you is covered, your contribution is fully deductible no matter what you earn.

If either of you is covered, the deduction phases out over specific income bands. For the 2026 tax year:³

Single filer covered by a workplace plan: full deduction at MAGI of $81,000 or less, partial between $81,000 and $91,000, none above $91,000.
Married filing jointly with the contributing spouse covered: full deduction at MAGI of $129,000 or less, partial between $129,000 and $149,000, none above $149,000.
Married filing jointly with only the other spouse covered: full deduction at MAGI of $242,000 or less, partial between $242,000 and $252,000, none above $252,000.
Married filing separately and covered: partial deduction under $10,000, none at $10,000 or more.

If your income runs past the phase-out, you can still contribute. The contribution simply becomes non-deductible, which changes the tax math on the back end and requires paperwork discussed further down.

Tax-Free Growth Inside the Account

Once your money is in, everything the account earns compounds without an annual tax bill. Investment gains, dividends, and interest all accumulate untaxed as long as they stay inside the IRA.¹ In a regular brokerage account, you would owe capital gains tax each time you sold at a profit and income tax on dividends every year. Inside the IRA, those earnings reinvest in full and compounding works on a larger balance. Over decades the difference is substantial.

A few assets are off-limits. Federal law prohibits life insurance contracts and collectibles inside any IRA. Collectibles include artwork, rugs, antiques, gems, stamps, most coins, and alcoholic beverages, with narrow exceptions for certain government-minted gold and silver coins and specific bullion. If you invest IRA funds in a prohibited collectible, the IRS treats the amount as a distribution in the year of the purchase, triggering income tax and potentially the 10% early withdrawal penalty.⁵ Individual custodians often impose their own additional limits, such as refusing to hold real estate or closely held company stock.

What You Owe When You Withdraw

The deferred bill comes due at distribution. Every dollar you pull out of a fully deductible Traditional IRA is taxed as ordinary income at whatever marginal rate applies to you that year.⁶ A retiree in the 22% bracket who withdraws $50,000 would owe roughly $11,000 in federal income tax on that distribution, plus any state tax. Because many people drop into a lower bracket in retirement, the deferred tax often ends up smaller than it would have been during working years, but that outcome is not guaranteed.

Withdrawals before age 59½ generally trigger an additional 10% tax on top of the ordinary income tax.⁷ For someone in the 24% bracket, an early withdrawal can cost 34% or more in combined federal tax before state tax is even considered.

Exceptions to the 10% Early Withdrawal Penalty

The additional 10% does not apply in several situations, though the underlying income tax still does:⁸

First-time home purchase, up to $10,000 in lifetime IRA distributions.
Qualified higher education expenses for you, your spouse, or your children.
Health insurance premiums while unemployed, if you received unemployment compensation for at least 12 consecutive weeks.
Total and permanent disability.
A series of substantially equal periodic payments taken over your life expectancy, continued for at least five years or until you reach 59½, whichever is longer.
One emergency personal expense distribution per year of up to $1,000, available since 2024.

Non-Deductible Contributions and Form 8606

If you made contributions you could not deduct because your income exceeded the phase-out, part of every future withdrawal is a tax-free return of money you already paid tax on. You track that basis on IRS Form 8606, which you must file for any year you make a non-deductible contribution or take a distribution from an account that contains non-deductible funds.⁹ Skipping the form does not erase your basis, but without records, proving it to the IRS gets very hard, and you risk paying tax twice. Keep every Form 8606 for as long as any Traditional IRA balance remains.

When Deferral Ends: Required Minimum Distributions

Tax deferral has an expiration date. Once you reach 73, federal law requires you to begin taking annual Required Minimum Distributions (RMDs) from your Traditional IRA.¹⁰ Under SECURE Act 2.0, the starting age moves to 75 in 2033 for people born in 1960 or later.

Your RMD is calculated by dividing your prior-year December 31 balance by a life expectancy factor from the IRS Uniform Lifetime Table.¹¹ The divisor shrinks each year, so the required percentage grows as you age. You can delay your first RMD until April 1 of the year after you turn 73, but doing so means taking two RMDs in that second year, which can push you into a higher bracket.

Missing an RMD carries an excise tax of 25% on the amount you should have withdrawn, dropping to 10% if you correct the shortfall within two years by taking the missed distribution and filing an updated return.¹²

What Happens at Death

Deferral does not fully carry over to whoever inherits the account. A surviving spouse has the most flexibility and can roll the account into their own IRA, resetting the standard rules.¹³ Most non-spouse beneficiaries who inherited from an owner who died in 2020 or later must empty the account by December 31 of the year containing the 10th anniversary of the owner’s death, with every dollar taxed as ordinary income in the year it comes out. A narrow group of eligible designated beneficiaries, including minor children of the owner, individuals who are disabled or chronically ill, and beneficiaries no more than 10 years younger than the deceased, can still stretch distributions over their own life expectancy.¹⁴
