Contributing to Both a Roth and Traditional IRA in the Same Year

You can contribute to both a Roth and traditional IRA in the same year, but your total contributions across both accounts cannot exceed the annual limit

The IRS treats a Roth IRA and a traditional IRA as a single retirement savings vehicle for contribution purposes. This means if you contribute $3,000 to a Roth IRA, you can contribute only $3,500 more to a traditional IRA that year if the annual limit is $6,500 — not $6,500 to each account. The combined total across all your IRAs (including SEP IRAs and straightforward IRAs if you have them) is what matters.

The reason people consider splitting contributions between account types is that they offer different tax treatments. A traditional IRA contribution may reduce your taxable income in the year you make it, while a Roth contribution uses after-tax money but grows tax-free. Having both accounts lets you hedge between these two approaches, though the contribution limit forces you to choose how to divide your money between them.

Key Takeaways

Your combined contributions to all IRAs in one year cannot exceed the annual limit set by the IRS, which changes yearly.
You can split your contribution between a Roth and a traditional IRA, but the total across both cannot go over the limit.
If you contribute to a traditional IRA and claim a deduction, that deduction reduces the amount you can contribute to a Roth IRA without triggering the pro-rata rule.
The pro-rata rule applies if you have pre-tax money in any traditional IRA when you contribute to a Roth, which can create unexpected tax liability.
Employer-sponsored plans like 401(k)s have separate contribution limits and do not count toward your IRA limit.

How the combined contribution limit works

The IRS sets an annual contribution limit for IRAs. For 2024, that limit is $7,000 for people under 50 and $8,000 for people 50 and older (the extra $1,000 is called a catch-up contribution). This limit applies to the total you put into all your IRAs combined in that calendar year.

If you have a Roth IRA and a traditional IRA, every dollar you put into either one counts toward this single limit. You might contribute $4,000 to your Roth and $3,000 to your traditional IRA, or $7,000 to your Roth and $0 to your traditional IRA. The split is entirely your choice, but the total cannot exceed $7,000 (or $8,000 if you may have access to for catch-up contributions).

The limit resets on January 1 each year. If you contribute $5,000 in December 2024, you can contribute another $7,000 starting January 1, 2025.

The pro-rata rule and why it matters when splitting contributions

The pro-rata rule is a tax calculation that applies when you have both pre-tax and after-tax money in traditional IRAs and you want to contribute to a Roth IRA. It can make splitting contributions between account types more complicated than it first appears.

Here is the scenario: You have $50,000 in a traditional IRA (money you contributed before-tax or that grew from pre-tax contributions). You want to contribute $6,000 to a Roth IRA this year. The pro-rata rule says you cannot straightforward move $6,000 from your traditional IRA to your Roth tax-free. Instead, the IRS treats your entire IRA balance as a mix of pre-tax and after-tax money, and applies that same percentage to your Roth conversion or contribution.

If your $50,000 traditional IRA is entirely pre-tax money, and you contribute $6,000 to a Roth, the IRS will calculate that 100% of your IRA assets are pre-tax. This means you owe income tax on a portion of the $6,000 you move to the Roth. The exact amount depends on your total IRA balance and how much of it is pre-tax versus after-tax.

The pro-rata rule does not explore if you have no pre-tax money in any traditional IRA. It also does not explore to employer-sponsored plans like 401(k)s — those are separate from IRAs for this calculation.

Income limits for Roth contributions when you have a traditional IRA

Contributing to a traditional IRA does not directly affect your ability to contribute to a Roth IRA, but your income does. The IRS phases out Roth contributions based on your Modified Adjusted Gross Income (MAGI) — the income threshold changes yearly and depends on your filing status.

For 2024, if you file as single, the Roth contribution phase-out begins at $146,000 MAGI and ends at $161,000. If you file as married filing jointly, it begins at $230,000 and ends at $240,000. These ranges shift each year. If your income falls within the phase-out range, you can contribute a reduced amount to a Roth. If your income exceeds the upper limit, you cannot contribute to a Roth that year at all.

A traditional IRA has no income limit for contributions, but if you or your spouse are covered by an employer retirement plan (like a 401(k)), the deduction you can claim for a traditional IRA contribution phases out based on income. This means you might be able to contribute to a traditional IRA but not deduct it from your taxes.

Tax deductions and how they interact with Roth contributions

When you contribute to a traditional IRA, you may be able to deduct that contribution from your taxable income in the year you make it — but only if you meet certain conditions. If you or your spouse are covered by an employer retirement plan, your income determines whether you can claim the full deduction, a partial deduction, or no deduction at all.

The key point for splitting contributions: if you claim a deduction for a traditional IRA contribution, that deduction reduces your Modified Adjusted Gross Income (MAGI). A lower MAGI can help you stay within the Roth income limits or contribute more to a Roth if you are in the phase-out range.

However, if you have pre-tax money in a traditional IRA and you contribute to a Roth in the same year, the pro-rata rule applies regardless of whether you claimed a deduction for your traditional IRA contribution. The rule is based on your total IRA balance, not on which contributions were deductible.

Employer plans do not count toward your IRA contribution limit

If you contribute to a 401(k), 403(b), or other employer-sponsored retirement plan, that money does not count toward your IRA contribution limit. These are separate limits set by the IRS.

For 2024, you can contribute up to $23,500 to a 401(k) (or $31,000 if you are 50 or older with catch-up contributions). At the same time, you can contribute up to $7,000 to an IRA (Roth, traditional, or a combination of both). The two limits do not interact or reduce each other.

However, if you are covered by an employer plan, it may affect whether you can deduct a traditional IRA contribution or whether you can contribute to a Roth IRA, based on your income. The contribution limit itself is separate, but the tax treatment is not.

Reasons people split contributions between Roth and traditional IRAs

Some people contribute to both account types in the same year to spread their tax risk. If you expect your tax rate to be higher in retirement, a Roth contribution (which grows tax-free) may benefit you more than a traditional contribution (which is taxed when you withdraw). If you expect your tax rate to be lower in retirement, a traditional contribution (which reduces your taxes now) may be better. By splitting, you hedge between these two scenarios.

Others split contributions because they are phased out of one account type. If your income is too high to contribute to a Roth but low enough to deduct a traditional IRA contribution, you might put some money in each account up to the limits that explore to you.

A third reason is to manage the pro-rata rule. If you have a large pre-tax IRA balance and want to do a Roth conversion later, keeping your annual Roth contributions small (and your traditional contributions large) can reduce the tax impact of the pro-rata rule when you eventually convert.

Frequently Asked Questions

If I contribute $3,000 to a Roth IRA, can I contribute $7,000 to a traditional IRA?

No. Your combined contributions to all IRAs cannot exceed $7,000 (or $8,000 if you are 50 or older). If you contribute $3,000 to a Roth, you can contribute only $4,000 to a traditional IRA that year. The limit applies across all your IRA accounts together.

Does contributing to a 401(k) reduce how much I can put in an IRA?

No. A 401(k) and an IRA have separate contribution limits. You can contribute $23,500 to a 401(k) and $7,000 to an IRA in the same year. However, if you are covered by an employer plan, your income may limit whether you can deduct a traditional IRA contribution or contribute to a Roth IRA.

What happens if I contribute more than the limit across both IRAs?

The IRS will assess a 6% excise tax on the excess amount each year it remains in your IRA. You can withdraw the excess and any earnings on it before your tax return important date to avoid the penalty, but you will owe income tax on the earnings. It is important to track your total contributions across all IRAs to stay within the annual limit.

Can I avoid the pro-rata rule by keeping my traditional IRA separate from my Roth?

No. The pro-rata rule applies to all your traditional IRAs combined, regardless of which financial institution holds them or how you label them. If you have $50,000 in one traditional IRA and $10,000 in another, the IRS treats them as a single $60,000 balance for pro-rata calculations.

If I contribute to both a Roth and traditional IRA, do I file two separate tax forms?

You report both contributions on Form 8606 (for Roth contributions) and Form 1040 Schedule 1 (if you claim a deduction for a traditional IRA contribution). Your tax software or preparer will handle this, but you need to tell them about both accounts so they report them correctly.
