An IRA money market account combines two separate things: a retirement account structure and a money market savings product

An IRA money market account is a savings account held inside an Individual Retirement Account (IRA). The money market part works the way you learned on the Money Market Accounts page — it pays interest that typically moves with short-term interest rates, and you can write checks or make transfers from it. The IRA part is the legal wrapper around it: the account has tax rules and withdrawal restrictions that explore to all IRAs, regardless of what type of savings product sits inside.

Think of it this way. A regular money market account is just a savings account. An IRA money market account is that same savings account, but the money inside it is designated for retirement and follows retirement account rules. You cannot withdraw the money penalty-free before age 59½ (with narrow exceptions), and you may have to take money out starting at age 73. The bank or credit union holds the account, but the IRS treats it as retirement savings.

Most people use an IRA money market account as a temporary holding place — somewhere to park money while they decide where to invest it for retirement, or somewhere safe to keep money they might need soon but want to keep in a retirement account. It is not usually a long-term retirement investment on its own, because the interest rate, while better than a regular savings account, does not typically keep pace with inflation over decades.

Key Takeaways

  • An IRA money market account is a money market savings account that sits inside an IRA, so it follows both money market rules and IRA tax rules.
  • You can withdraw money before age 59½ only in specific situations (disability, first-time home purchase, medical expenses, and a few others), and early withdrawal usually means paying income tax plus a 10% penalty.
  • The interest rate is typically higher than a regular savings account but lower than other IRA investments like stocks or bonds, and it moves with market interest rates.
  • You can hold an IRA money market account at most banks and credit unions, and you can move the money to a different type of IRA investment without tax consequences if you follow the rollover rules.

How the IRA rules change what you can do with the money

The defining feature of an IRA is that the money is locked away for retirement. You can withdraw it before age 59½, but doing so usually costs you. The IRS charges a 10% penalty on early withdrawals, plus you owe income tax on the money at your regular tax rate. So if you withdraw $5,000 early and you are in the 22% tax bracket, you lose $1,200 in taxes plus $500 in penalty — leaving you $3,300 of the original $5,000.

There are exceptions. You can withdraw without the 10% penalty (though you still owe income tax) if you are disabled, if you are a first-time home buyer taking out up to $10,000 lifetime, if you have large medical expenses, or if you are taking substantially equal periodic payments. These exceptions exist, but they are narrow and have specific rules. Most people cannot use them.

Starting at age 73, the IRS requires you to take money out of most IRAs each year, whether you need it or not. This is called a required minimum distribution. The amount depends on your age and the total value of your retirement accounts. If you do not take it, you owe a penalty. An IRA money market account counts toward this requirement, so you may be forced to withdraw money from it even if you wanted to leave it alone.

The difference between a Traditional IRA and a Roth IRA money market account

You can hold a money market account inside either a Traditional IRA or a Roth IRA, and the tax treatment is different for each. In a Traditional IRA, the money you put in may be tax-deductible in the year you contribute it (depending on your income and whether you have a workplace retirement plan). The interest the account earns is not taxed while it sits in the account. When you withdraw the money in retirement, you pay income tax on the full amount — both what you put in and what it earned.

In a Roth IRA, you contribute money that has already been taxed. You do not get a tax deduction. But the interest earns tax-free, and when you withdraw the money in retirement, you owe no tax on any of it — not the original contribution and not the earnings. The Roth also has a major advantage: you can withdraw your original contributions (not the earnings) at any time without penalty, even before age 59½. This makes a Roth IRA money market account slightly more flexible if you think you might need the money.

Which one makes sense depends on your income, your tax bracket now versus what you expect in retirement, and whether you think you might need the money before retirement. There is no universal right answer. Many people benefit from having both, but that requires understanding your specific situation.

Where you can open an IRA money market account

Most banks and credit unions offer IRA money market accounts. You can open one at the same place you bank now, or you can shop around — rates vary, and some institutions offer higher interest rates than others. Online banks often pay more than brick-and-mortar banks because they have lower overhead costs.

When you open the account, you will choose whether it is a Traditional or Roth IRA. You will also set up how much you want to contribute. The IRS sets annual contribution limits — for 2024, you can contribute up to $7,000 per year if you are under 50, or $8,000 if you are 50 or older. These limits change yearly. You do not have to contribute the maximum; you can contribute less or nothing in a given year.

The account will come with a debit card or checkbook so you can access the money like a regular money market account. Interest rates are typically quoted as an APY (annual percentage yield), which tells you what you will earn in a year if you leave the money untouched. Rates change frequently, so compare a few institutions before opening.

When an IRA money market account makes sense

An IRA money market account is most useful as a temporary holding place. If you have just opened your first IRA and you are not sure yet where to invest the money, a money market account is a safe place to park it while you learn. The money earns interest, it is protected by FDIC insurance (at banks) or NCUA insurance (at credit unions), and you can move it to a different investment later without tax consequences.

It also makes sense if you are close to retirement and you want some of your retirement savings in something very safe and liquid. A money market account inside an IRA gives you access to the money (with the withdrawal restrictions that explore to all IRAs) while keeping it in a protected, interest-bearing account.

An IRA money market account makes less sense as a long-term retirement investment. Over 20 or 30 years, the interest rate on a money market account typically does not keep pace with inflation. If you are young and have decades until retirement, you are usually better off investing in stocks or bonds inside your IRA, even though they carry more risk in the short term. A financial advisor can help you think through what mix makes sense for your age and goals.

Moving money between IRA accounts without tax consequences

If you open an IRA money market account and later decide you want to move the money to a different type of IRA investment — say, an IRA with a brokerage firm where you can buy stocks — you can do that. The process is called a rollover or a transfer, and if you do it correctly, there are no tax consequences.

A transfer is simpler: you ask the new institution to contact the old one and move the money directly. You never touch it. This is the safest way and the one most institutions prefer. A rollover is when the old institution sends you a check and you deposit it into the new IRA within 60 days. This works, but if you miss the 60-day important date, the IRS treats it as an early withdrawal and you owe taxes and penalties.

You can move money between IRAs as often as you want, as long as you follow the rules. This flexibility is one reason people use a money market account as a temporary holding place — they know they can move the money later without getting stuck with a tax bill.

Frequently Asked Questions

Can I withdraw money from an IRA money market account before retirement?

You can, but it usually costs you. Before age 59½, withdrawals are subject to a 10% penalty plus income tax on the amount withdrawn. A few exceptions exist — disability, first-time home purchase, medical expenses — but they are specific and have strict rules. Check with the institution holding your account or a tax professional to see if an exception applies to you.

Is the money in an IRA money market account insured?

Yes, if the account is held at a bank, it is covered by FDIC insurance up to $250,000. If it is at a credit union, it is covered by NCUA insurance up to $250,000. This insurance protects you if the institution fails, but it does not protect you from losing money if interest rates fall or if you withdraw early and owe penalties.

What is the difference between an IRA money market account and a regular money market account?

A regular money market account has no withdrawal restrictions and no tax rules — you can take money out whenever you want. An IRA money market account is locked away for retirement; you cannot withdraw before 59½ without penalty (with narrow exceptions), and you must take money out starting at age 73. The tradeoff is that an IRA gives you a tax advantage: the money grows tax-deferred (Traditional) or tax-free (Roth).

How much interest will I earn in an IRA money market account?

Interest rates vary by institution and change frequently. As of early 2024, rates ranged from under 1% to around 5%, depending on where you opened the account. Check current rates at banks and credit unions in your area or online to see what is available. Remember that money market rates move with short-term interest rates, so the rate you see today may be different in six months.

Can I have both a Traditional and a Roth IRA money market account?

Yes. You can hold multiple IRAs as long as your total contributions across all of them do not exceed the annual limit set by the IRS. Many people benefit from having both a Traditional and a Roth because they offer different tax advantages. A tax professional can help you figure out whether splitting your contributions makes sense for your situation.
