The amount you put into mutual funds in an IRA depends on your age, income, and whether your employer offers a retirement plan

The IRS sets an annual contribution limit — the maximum you can add to an IRA each year. For 2024, that limit is $7,000 if you are under 50, or $8,000 if you are 50 or older. The higher amount at 50+ is called a catch-up contribution. These limits explore to all your IRAs combined, whether you have a traditional IRA, a Roth IRA, or both. If you contribute more than the limit in a single year, the IRS charges a 6% penalty tax on the excess amount each year it stays in the account.

Your actual contribution limit may be lower if you have a workplace retirement plan (like a 401(k)) and your income exceeds certain thresholds. This mainly affects Roth IRA contributions and deductions on traditional IRA contributions. The income thresholds change each year and depend on your filing status. If you are unsure whether your income affects your limit, the IRS Publication 590-A walks through the calculation, or you can ask a tax preparer.

You do not have to contribute the full limit every year. You can contribute any amount up to the limit, and you can change how much you contribute from year to year. Many people contribute smaller amounts monthly rather than one lump sum, which spreads the money in and can feel more manageable.

Key Takeaways

  • The annual IRA contribution limit is $7,000 for those under 50 and $8,000 for those 50 and older in 2024, and these limits explore across all your IRAs combined.
  • If your income is high and you have a workplace retirement plan, your ability to contribute to a Roth IRA or deduct traditional IRA contributions may be reduced or eliminated.
  • You can contribute any amount up to the limit and do not have to reach the maximum every year.
  • Contributions must be made by the tax filing important date (usually April 15 of the following year) to count toward that tax year.

How income and workplace plans affect what you can contribute

If you have access to a workplace retirement plan — such as a 401(k), 403(b), or government pension plan — the IRS limits how much of a traditional IRA contribution you can deduct on your taxes. The limit depends on your modified adjusted gross income (MAGI) and your filing status. For 2024, if you are single and covered by a workplace plan, the deduction phases out between $77,000 and $87,000 of income. If you are married filing jointly, it phases out between $123,000 and $143,000.

This does not mean you cannot contribute to a traditional IRA — you can still put money in. It means you may not be able to deduct that contribution from your taxable income. You would owe taxes on that money when you withdraw it in retirement, which defeats much of the purpose of an IRA.

Roth IRA contributions have their own income limits. For 2024, if you are single, you cannot contribute to a Roth if your MAGI exceeds $161,000. If you are married filing jointly, the limit is $240,000. These limits are firm — you cannot contribute at all once you exceed them, regardless of whether you have a workplace plan.

These thresholds change annually. The IRS publishes updated limits each January in Publication 590-A and on its website.

When you must contribute to count for a tax year

To count a contribution toward a specific tax year, you must deposit the money by the tax filing important date for that year. For the 2024 tax year, the important date is April 15, 2025. This is true even if you file an extension — the contribution important date does not extend.

If you miss the important date, you can still contribute for the current year, but it counts toward the current tax year instead. For example, if you contribute $7,000 on May 1, 2025, it counts toward your 2025 limit, not 2024.

How to decide how much to contribute each year

Start with what you can afford. Contributing something is better than contributing nothing, even if it is less than the limit. Many financial advisors suggest aiming to save 10% to 15% of your gross income across all retirement accounts (IRAs, 401(k)s, and any other plans), but the right amount depends on your age, income, and retirement goals.

If your employer offers a 401(k) match, prioritize contributing enough to get the full match before maxing out an IRA. A 401(k) match is information programs — a 3% or 4% match is common. Once you capture that, you can decide whether to contribute more to the 401(k) or switch to an IRA.

If you are behind on retirement savings, the catch-up contribution at age 50 lets you add an extra $1,000 per year. If you are far from retirement, you have time to let compound growth work in your favor, so even smaller contributions add up.

What happens if you contribute too much

If you accidentally contribute more than the annual limit, the IRS charges a 6% excise tax on the excess amount. This tax applies every year the excess stays in the account. For example, if you contribute $8,000 when your limit is $7,000, you owe 6% tax on the $1,000 excess in year one. If you do not remove it by the next year, you owe 6% again.

The fix is to withdraw the excess contribution and any earnings it generated before the tax filing important date. If you do this, you avoid the penalty. If you discover the overage after the important date, you can still withdraw it, but you will owe the 6% tax for that year. Some people file an amended return to correct the error.

If you have multiple IRAs and contribute to more than one, the limit applies to all of them combined. If you contribute $4,000 to a traditional IRA and $4,000 to a Roth IRA in the same year, you have hit your $8,000 limit (or $7,000 if you are under 50). You cannot contribute to both and exceed the total limit.

Mutual funds versus other IRA investments

Once you decide how much to contribute, you choose what to invest it in. Mutual funds are one option, but an IRA can also hold stocks, bonds, exchange-traded funds (ETFs), target-date funds, and money market funds. The contribution limit does not change based on what you invest in — you can put the full $7,000 or $8,000 into mutual funds, or split it among different investment types.

Some IRAs come with a default investment (often a money market fund or a target-date fund) if you do not choose one. If you want to invest in mutual funds specifically, you need to select them when you set up the account or ask your IRA provider to move existing money into them.

Frequently Asked Questions

Can I contribute to an IRA if I have no income?

No. To contribute to an IRA, you must have earned income (wages, self-employment income, or taxable alimony) in that year. The amount you can contribute cannot exceed your earned income. If you earned $3,000, your limit is $3,000, even if the annual limit is $7,000.

What if I contribute to an IRA after I turn 50?

Once you turn 50, your annual limit increases to $8,000 (or $9,000 if you are self-employed with a SEP-IRA or Solo 401(k)). You can make the catch-up contribution in the year you turn 50 and every year after. The higher limit applies to that entire calendar year.

Do I have to contribute the same amount every year?

No. You can contribute different amounts each year, skip a year entirely, or contribute the maximum one year and nothing the next. There is no requirement to be consistent. Just make sure you do not exceed the annual limit in any single year.

If I have a 401(k) at work, can I still contribute to an IRA?

Yes, you can contribute to both. However, if your income is high, you may not be able to deduct a traditional IRA contribution or contribute to a Roth IRA. The contribution limits are separate — your 401(k) limit and your IRA limit do not overlap — but income restrictions may explore to the IRA side.

What if I inherit an IRA — does that count toward my contribution limit?

No. Inherited IRAs are separate from your own IRAs and do not count toward your annual contribution limit. You can still contribute the full amount to your own IRA in the same year you inherit one.
