The basic steps to fund your traditional IRA

You fund a traditional IRA by transferring money from your bank account directly to the IRA custodian — the financial institution that holds the account. Most people do this through an online transfer, a check, or an automatic recurring deposit. The custodian is usually a bank, brokerage firm, or credit union. You choose where to open the account, and that institution handles the deposit process.

The money you contribute sits in the IRA until you invest it or withdraw it. Contributing and investing are two separate actions. You can contribute cash to the account without immediately buying stocks, bonds, or mutual funds — many people leave contributions in a cash sweep account while they decide what to do with it.

There is no single "IRA contribution form" you fill out with the government. You work directly with your chosen financial institution. They will ask you to complete their account setup paperwork, which includes your Social Security number, address, and employment information. After that, you can fund the account whenever you want during the year.

Key Takeaways

  • You contribute to a traditional IRA by moving money from your bank account to the IRA custodian you choose — usually a bank or brokerage.
  • The annual contribution limit is $7,000 for people under 50 and $8,000 for people 50 and older, and this limit applies across all IRAs you own combined.
  • You can contribute until the tax filing deadline of the following year (usually April 15), so a 2024 contribution can be made as late as April 15, 2025.
  • Your contributions may be tax-deductible in the year you make them, but deductibility phases out if you or your spouse have a workplace retirement plan and earn above a certain income.
  • You must have earned income in the year you contribute — you cannot fund an IRA with investment returns, gifts, or unemployment benefits.

Annual contribution limits and how they work

The IRS sets a yearly limit on how much you can put into a traditional IRA. For 2024, the limit is $7,000 if you are under age 50, and $8,000 if you are 50 or older. The extra $1,000 for people 50 and up is called a catch-up contribution. These limits change each year, and the IRS announces the new amount in October for the following year.

The limit applies to all your IRAs combined, not per account. If you own two traditional IRAs and one Roth IRA, your total contributions across all three cannot exceed $7,000 (or $8,000 if you are 50+) in a single year. If you contribute more than the limit, the IRS charges a 6% penalty tax on the excess amount each year it remains in the account, so it is important to track your total across all accounts.

You do not have to contribute the full limit. You can put in $2,000, $5,000, or any amount up to the limit. Many people contribute smaller amounts throughout the year rather than one lump sum.

Earned income requirement and who can contribute

You can only contribute to a traditional IRA if you had earned income in that year. Earned income means wages, salary, self-employment income, or other compensation for work. It does not include investment returns, interest, dividends, rental income, Social Security, unemployment benefits, or gifts.

Your contribution cannot be larger than your earned income for the year. If you earned $3,500 in 2024, you can contribute up to $3,500 to your IRA for that year, even though the annual limit is $7,000. A spouse with no earned income can still contribute to an IRA if the other spouse has earned income — this is called a spousal IRA contribution — but the couple's combined contributions still cannot exceed the household earned income.

If you are retired or have no earned income in a given year, you cannot make a contribution to a traditional IRA for that year. However, you can still make contributions in years when you do have earned income, such as from part-time work or self-employment.

Tax deductibility and income phase-outs

One major advantage of a traditional IRA is that your contributions may be tax-deductible — meaning you can subtract them from your taxable income when you file your tax return. However, deductibility is limited if you or your spouse have access to a workplace retirement plan like a 401(k) or 403(b).

If you do not have a workplace retirement plan and your spouse does not either, your entire contribution is deductible regardless of income. If you do have a workplace plan, your deduction begins to phase out once your income reaches a certain level. For 2024, the phase-out range for single filers is $77,000 to $87,000 of modified adjusted gross income. For married couples filing jointly where the contributing spouse has a workplace plan, it is $123,000 to $143,000. These ranges change each year.

If your income falls within the phase-out range, you can deduct part of your contribution. If your income exceeds the upper end of the range, you cannot deduct any of it. You can still contribute to the account — the money just will not reduce your taxable income that year. When you withdraw the money later, you will owe income tax on the earnings, but not on the non-deductible portion of the contribution.

Contribution deadlines and timing

You can contribute to a traditional IRA for a given tax year until the tax filing deadline of the following year. For the 2024 tax year, you have until April 15, 2025 to make a contribution and claim it on your 2024 tax return. If April 15 falls on a weekend or holiday, the deadline moves to the next business day.

You do not have to wait until tax time to contribute. Many people contribute throughout the year — monthly, quarterly, or whenever they have money available. The timing of your contribution does not affect the tax year it counts toward, as long as you make it by the deadline.

If you miss the April deadline, you can still contribute to the account, but it will count toward the following tax year instead. For example, if you contribute on May 1, 2025, it counts as a 2025 contribution, not a 2024 one. There is no way to go back and claim a late contribution for a prior year.

Methods to fund your IRA

Most financial institutions offer several ways to move money into your IRA. The most common method is an electronic bank transfer — you log into your IRA account online and initiate a transfer from your linked checking or savings account. This usually takes one to three business days to complete.

You can also mail a check to the custodian's address. The check should be made payable to the custodian (not to yourself), and you should include a note with your IRA account number. Mail deposits take longer — typically five to ten business days — and there is a small risk of loss or delay.

Some custodians allow automatic recurring deposits, where you set up a monthly or quarterly transfer that happens without you having to initiate it each time. This is useful if you want to contribute a fixed amount regularly. You can also do a one-time transfer from another IRA or retirement account, which is called a rollover or transfer — this has different rules and timing requirements than a regular contribution.

What happens after you contribute

Once the money reaches your IRA, it sits in a cash account until you decide what to do with it. You are not required to invest it immediately. Some people leave contributions in cash for weeks or months while they research investment options or wait for market conditions they prefer.

When you are ready, you can use the money to buy stocks, bonds, mutual funds, exchange-traded funds (ETFs), or other investments offered by your custodian. Your custodian's website or app will show you the investment options available. Different custodians offer different menus — some have thousands of options, others have a limited selection.

You can also move money between investments within the IRA without tax consequences. Buying and selling inside the account does not trigger capital gains tax, which is one of the main benefits of using an IRA. The tax bill comes later, when you withdraw money in retirement.

Frequently Asked Questions

Can I contribute to a traditional IRA if I have a 401(k) at work?

Yes, you can contribute to both. However, if you have a 401(k) or similar workplace plan, your traditional IRA contribution may not be fully tax-deductible. The deduction phases out based on your income. You can still contribute the money — it just might not reduce your taxable income that year.

What if I contribute too much by mistake?

If you exceed the annual limit, you should contact your custodian and ask them to return the excess contribution plus any earnings on it. The IRS charges a 6% penalty tax each year on excess amounts left in the account. Removing the excess before your tax deadline usually avoids the penalty, but you may owe tax on the earnings portion.

Can I contribute money I received as a gift or inheritance?

No. You can only contribute earned income — wages, salary, or self-employment income. A gift or inheritance does not count as earned income. However, you can use a gift to fund your regular bank account, and then contribute from that account to your IRA.

Do I have to contribute the same amount every year?

No. You can contribute different amounts each year, or skip a year entirely if you do not have earned income. There is no minimum contribution amount, and no requirement to contribute every year. You only pay the 6% penalty if you contribute more than the limit, not if you contribute less.

What if I turn 50 during the year?

You can use the higher catch-up limit ($8,000 for 2024) for the year you turn 50. You do not have to wait until the following year. Your custodian's system should automatically recognize your age and allow the higher contribution limit once you update your birthdate in your account.
