Roth IRA Tax Benefits & Limits Explained

If you’re looking to grow your retirement savings and keep more of your money in the long run, a Roth IRA might be just what you need. Unlike traditional IRAs, which give you an upfront tax deduction, Roth IRAs offer something just as valuable: tax-free withdrawals in retirement.

Let’s walk through how Roth IRAs work, who qualifies, how much you can contribute in 2025, and why this retirement plan could be especially useful if you expect to be in a higher tax bracket later in life.

How TaxAct can help with Roth IRAs

Navigating Roth IRA rules can be confusing, but TaxAct® is here to simplify the process. Whether you need help reporting a distribution, figuring out your eligibility based on your modified AGI, or dealing with an excess contribution, we’ll walk you through every step to help ensure everything gets reported correctly.

What is a Roth IRA?

A Roth IRA (short for Roth individual retirement account) is a retirement savings account that you fund with after-tax dollars. That means you don’t get a tax break when you contribute, but your money grows tax-free, and qualified withdrawals in retirement are not taxed.

This is different from a traditional IRA, where contributions are tax-deductible, but withdrawals are taxed as ordinary income later on.

How does a Roth IRA work?

No tax deduction now: Contributions to a Roth IRA aren’t tax-deductible, so they don’t lower your taxable income.
Tax-free growth: Your investments can grow without being taxed each year.
Tax-free withdrawals later: As long as you meet the rules (more on that soon), your retirement withdrawals are completely tax-free.
Investment options: IRAs offer a wider range of investment choices — including mutual funds, stocks, annuities, and bonds — compared to a typical employer-sponsored 401(k), giving you more control over how your money grows.
No required minimum distributions (RMDs): Unlike traditional IRAs, you’re never forced to take money out during your lifetime.
Can contribute at any age: The only requirement for contributing to an IRA is to have earned income; there’s no age limit for making contributions.

Roth IRA contribution limits 2025

There is a limit to how much you can contribute to your Roth IRA each year. The limits for both tax years 2024 and 2025 are:

Up to $7,000 if you’re under age 50
Up to $8,000 if you’re 50 or older (this includes a catch-up contribution)

Keep in mind that these are combined limits across all your IRA accounts. If you’re contributing to both a traditional IRA and a Roth IRA, your total contribution can’t go over these limits.

2025 Roth IRA income limits

Unlike a traditional IRA, Roth IRA eligibility comes with some income limitations. Your modified adjusted gross income (MAGI) must fall under a certain phaseout threshold to contribute to a Roth. Here are the income levels and contribution rules for each filing status in 2025:

Filing status	Full contribution if MAGI is under…	Partial contribution if MAGI is…	No contribution if MAGI is over…
Single and head of household Married filing separately (if you didn’t live with your spouse at all during the year)	$150,000	$150,000 to 164,999	$165,000
Married filing jointly or surviving spouse	$236,000	$236,000 to $245,999	$246,000

How much can I contribute to my Roth IRA if I am married filing separately?

This one’s a bit tricky. The IRS sets stricter rules for those who use the married filing separately tax status:

If you lived with your spouse at any time during the year: Your ability to contribute phases out completely if your MAGI is $10,000 or more. Even if your MAGI is less than $10,000, you can only make a partial contribution.
If you did not live with your spouse at all during the year: You’re treated as if you’re single for Roth IRA purposes, so the single filer income limits above apply to you instead.

So, depending on your living situation, your contribution limit could be severely reduced, or not impacted at all. If you plan to file your tax return separately from your spouse, it’s a good idea to double-check IRS rules to avoid penalties for over-contributing.

Is a Roth IRA tax-deductible?

Nope. Unlike a traditional IRA, Roth IRA contributions don’t reduce your taxable income in the year you contribute, so you can’t take a tax deduction for Roth contributions.

But that’s actually part of the long-term advantage of a Roth IRA! You’re paying taxes upfront, at today’s tax rates, so you can make tax-free withdrawals later in retirement. Roth accounts are a great option if you think you might be in a higher tax bracket in retirement or simply want to avoid paying any taxes on contributions when you withdraw them.

Do you pay taxes on a Roth IRA?

Roth IRA contributions are made with after-tax dollars. This means you pay the taxes upfront when you make a contribution, and you can withdraw the money tax-free in retirement as long as you follow the rules.

For your withdrawal to be considered a qualified distribution (meaning tax-free):

You must be at least 59 ½.
Your Roth account must be at least five years old.

There are also IRS exceptions that let you take penalty-free withdrawals early for certain things like a first-time home purchase or qualified education expenses.

How do I report Roth IRA distributions on my tax return?

Even though qualified Roth IRA distributions aren’t taxable, they still need to be reported on your federal tax return. The IRS uses this information to confirm that your withdrawals meet the rules for being tax-free. You’ll typically receive Form 1099-R from your IRA provider, and you’ll report the details on Form 8606 and your Form 1040.

Don’t worry about this part! TaxAct can guide you through the reporting process to make sure everything is filed correctly. For more help, check out our article on Form 1099-R and how to report IRA distributions.

Roth IRA tax benefits

To recap, let’s break down the most important Roth IRA tax advantages:

Tax-free growth: You won’t owe taxes on interest, dividends, or capital gains while your money grows.
Tax-free withdrawals in retirement: Withdraw your money without owing the IRS, as long as it’s a qualified distribution.
No required minimum distributions: Let your savings keep growing as long as you want.
Tax diversification: Having both pre-tax (like a 401(k) or traditional IRA) and after-tax accounts gives you flexibility when managing income taxes in retirement.
Great for younger or lower-income earners: If you’re in a low tax bracket now, you’ll likely benefit more from paying taxes up front while locking in tax-free income later when you’re presumably in a higher tax bracket.

What are the tax disadvantages of a Roth IRA?

While there are many Roth IRA benefits, there are a few potential downsides to consider:

No upfront tax break: Unlike traditional IRAs, Roth contributions don’t reduce your taxable income now.
Income limits apply: High earners may not qualify to contribute directly to a Roth IRA.
Contributions are made with after-tax dollars: You’ll still pay taxes on the money before it goes into the account.
Taxes on conversions: If you convert a traditional IRA to a Roth IRA, the converted amount is taxable in the year of the IRA conversion.
Early withdrawal penalties: While you can withdraw your contributions anytime, taking out earnings early can result in taxes and penalties unless you meet specific exceptions.

Roth IRA FAQs

Is Roth IRA pre-tax?

No, Roth IRAs are funded with after-tax dollars, which is the key to their tax-free withdrawal advantage in retirement.

How much does a Roth IRA contribution reduce taxes?

Roth IRA contributions don’t reduce your taxable income for the year you contribute. The real Roth IRA tax benefits come later, when you withdraw your money tax-free.

In comparison, a traditional IRA contribution is made with pre-tax money (reducing your taxable income) and grows tax-deferred until you withdraw it.

What are the advantages of Roth IRAs for students?

A Roth IRA can be a fantastic option for students. As long as you have earned income, you can contribute to a Roth IRA as a student or part-time worker. And because many students are likely in a lower tax bracket now than they will be in retirement, it’s a perfect time to take advantage of the biggest Roth IRA tax break — paying taxes now to avoid them later.

How do you calculate MAGI for Roth IRAs?

To figure out your MAGI for Roth IRA purposes, start with your adjusted gross income (AGI) and add back certain deductions, like student loan interest, tuition and fees, foreign earned income, and rental losses. Your MAGI determines whether you can make a full, reduced, or no contribution based on IRS income thresholds.

MAGI calculation may sound confusing, but don’t worry — our tax preparation software can help you crunch the numbers.

Can I have a Roth IRA and a Roth 401(k)?

Yes, you can contribute to both a Roth IRA and a Roth 401(k) in the same year, if you’re eligible for each. Just remember that each account has separate contribution limits. A Roth 401(k) is part of an employer-sponsored plan with higher contribution limits, while a Roth IRA is an individual account with income-based eligibility that we discussed above. Contributing to both can give you even more access to tax-free withdrawals later, if that’s what you’re looking for.

Can I contribute to a Roth IRA if I am self-employed?

Absolutely! If you’re self-employed and have earned income, you can contribute to a Roth IRA if you meet the income eligibility rules. You might also consider setting up a SEP IRA or a Solo 401(k), but contributing to a Roth IRA can still be a great way to grow your retirement savings with tax-free benefits.
