Roth vs Traditional IRA: The Tax Difference

By The Ledgerism Editorial Team · The Ledgerism Brief Editorial Team produces original, methodology-disclosed accounting and tax research—data trackers, databases, and reference guides built to be the most-cited source in the field. Every figure is verified against primary sources including FASB, the IRS, the PCAOB, NASBA, the AICPA, and state boards of accountancy.

The core difference between a Roth vs traditional IRA is when you pay tax. A traditional IRA can give you a deduction now and taxes the money when you withdraw it. A Roth IRA takes after-tax dollars now and pays out tax-free in retirement. For 2026, you can contribute up to $7,500 total across both ($8,600 if you are 50 or older), and the right choice usually depends on whether your tax rate is higher today or later.

Roth vs traditional IRA: the one-table summary

A Roth IRA is funded with after-tax money and grows tax-free, with no required distributions during your life. A traditional IRA may be deductible now and grows tax-deferred, but withdrawals are taxed as ordinary income and required distributions start at age 73. The table below compares the features that drive most decisions.

The $7,500 limit is a combined cap. Splitting money between both accounts does not raise it.

Pre-tax vs after-tax: how the tax actually works

A traditional IRA defers tax. A deductible contribution can reduce your taxable income in the contribution year, and both the contribution and its growth are taxed as ordinary income when you withdraw. A Roth IRA does the opposite: you get no deduction, but qualified withdrawals of both contributions and earnings are federal-income-tax-free.

The decision often comes down to your tax rate now versus later. If you expect a lower rate in retirement, deferring with a traditional IRA can win. If you expect the same or a higher rate, paying tax now through a Roth can leave more after-tax money.

A rough example: a $7,500 traditional contribution at a 24% marginal rate saves about $1,800 in tax this year. A Roth gives no upfront break, but if that account later withdraws at a 24% rate, the Roth’s tax-free growth can offset the lost deduction. The comparison depends on future rates, which no one controls.

Note the deduction depends on your income and workplace-plan coverage. See the income limits below.

2026 contribution limits and income limits

For 2026, the IRA contribution limit is $7,500, with a $1,100 catch-up for those 50 and older, for a total of $8,600. Anyone with earned income can contribute to a traditional IRA, but the deduction and the ability to fund a Roth phase out at higher income (measured by modified adjusted gross income, or MAGI).

The 2026 figures come from the IRS annual cost-of-living notice.

Two edge cases hold steady because they are not indexed for inflation: for someone married filing separately, both the Roth contribution phase-out and the traditional deduction phase-out run from $0 to $10,000. Above the top of each range, the deduction or Roth contribution is gone. If your income is too high for a Roth, a nondeductible traditional contribution is still allowed and gets reported on Form 8606; see Form 8606 and nondeductible IRA contributions for the mechanics.

If a deductible IRA contribution changes your tax picture, it can also shift your quarterly math. Our guide to estimated tax payments covers when to adjust.

Required minimum distributions (RMDs)

Traditional IRAs carry required minimum distributions. Roth IRAs do not, for the original owner. Under the SECURE 2.0 Act, traditional IRA owners must start RMDs by April 1 of the year after they turn 73 (the age rises to 75 in 2033), and each yearly amount is taxed as ordinary income.

Roth IRAs have no lifetime RMDs, so the balance can keep compounding tax-free for as long as you live. That makes a Roth a flexible tool for people who may not need the money at 73 and want to leave more to heirs.

Inherited IRAs follow separate rules. Most non-spouse beneficiaries must empty an inherited IRA within 10 years, and for an inherited traditional IRA those distributions are generally taxable, while an inherited Roth is generally tax-free.

Early withdrawal rules before age 59½

Roth IRAs are far more forgiving before age 59½. You can withdraw your Roth contributions (not earnings) at any time, tax-free and penalty-free, because that money was already taxed. Traditional IRA withdrawals before 59½ are generally taxed as ordinary income plus a 10% penalty.

Roth earnings are different. To withdraw earnings tax-free, you generally need to be 59½ or older and have held any Roth IRA for at least 5 years (the 5-year rule). Take earnings out early and they may face both tax and the 10% penalty.

Both account types share exceptions to the 10% penalty, including up to $10,000 for a first home, qualified higher-education costs, certain medical expenses, and disability. The penalty exceptions reduce the 10% charge but do not always erase ordinary income tax on a traditional IRA.

Who each IRA suits

A traditional IRA tends to fit people who want a deduction now and expect a lower tax rate in retirement, or whose income is too high to deduct elsewhere but who still want tax-deferred growth. A Roth tends to fit younger or lower-bracket savers, anyone expecting higher future rates, and people who value no RMDs and flexible early access to contributions.

• Choose traditional if: you want to cut this year’s taxable income, you are in a high bracket now, and you expect a lower bracket later.
• Choose Roth if: you are early in your career, you expect equal or higher future rates, or you want RMD-free, tax-free growth and heirs-friendly treatment.
• Consider both if: you want tax diversification, so you can control which “bucket” you draw from in retirement to manage your taxable income.

Many savers use an IRA alongside a workplace plan. For the employer-plan side of the picture, see the 401(k) and retirement plan report, and to keep paycheck withholding aligned with a new deduction, review how tax withholding works.

Frequently asked questions

Can I contribute to both a Roth and a traditional IRA in the same year?

Yes, but the annual limit is combined. For 2026 you can put a total of $7,500 across both accounts ($8,600 if you are 50 or older), split any way you like. You cannot contribute $7,500 to each. Roth eligibility still depends on your income, so a high MAGI may push more of your contribution toward the traditional side.

What income counts toward the IRA limits?

Eligibility is measured by modified adjusted gross income (MAGI), which starts from adjusted gross income and adds back certain items. The Roth phase-out and the traditional deduction phase-out both use MAGI. If you are near a threshold, small changes in income can affect eligibility. See our explainer on adjusted gross income for how AGI is built.

Is a traditional IRA contribution always tax deductible?

No. If neither you nor your spouse is covered by a workplace retirement plan, the deduction is generally full regardless of income. If you are covered, the deduction phases out inside the 2026 ranges shown above, and above the top of the range it disappears. A nondeductible contribution is still allowed and is tracked on Form 8606.

Do Roth IRAs ever require withdrawals?

Not for the original owner. Roth IRAs have no required minimum distributions during your lifetime, which lets the balance grow tax-free indefinitely. Beneficiaries are treated differently: most non-spouse heirs must fully distribute an inherited Roth IRA within 10 years, though those distributions are generally tax-free.

What is the Roth 5-year rule?

To withdraw Roth earnings tax-free, you generally must be at least 59½ and have held a Roth IRA for at least 5 years. The 5-year clock starts January 1 of the year of your first Roth contribution. Contributions themselves can always come out tax-free and penalty-free, so the rule mainly affects earnings.

Which IRA lowers my taxes this year?

Only a deductible traditional IRA reduces your current-year taxable income. A Roth contribution gives no upfront deduction; its benefit is tax-free withdrawals later. If a same-year tax cut is your goal and you qualify for the deduction, the traditional IRA is the one that moves your current tax bill.
