IRA Tax Deduction Rules

Broadly speaking, individual retirement accounts, or IRAs, offer some sort of tax benefit — either during the year that contributions are made or when distributions take place after retiring. But not all retirement accounts are taxed the same.

With a traditional IRA, it’s possible for certain individuals to both invest for their future and reduce their present tax liability. For tax year 2024, the maximum IRA deduction is $7,000 for people younger than 50, and $8,000 for those 50 and older. For tax year 2025, the maximum IRA deduction remains at $7,000 for people younger than 50, and $8,000 for those 50 and older.

To maximize deductions in a given year, the first step is understanding how IRA tax deductions work. A good place to start is learning the differences between common retirement accounts — and their taxation. And since each financial situation is different, an individual may also want to speak with a tax professional about their specific situation.

Read on to learn more about IRA tax deductions, including how both traditional and Roth IRA accounts are taxed in the U.S.

What Is a Tax Deduction?

First, here’s a quick refresher on tax deductions for income taxes — the tax owed/paid on a person’s paycheck, bonuses, tips, and any other wages earned through work. “Taxable income” also includes interest earned on bank accounts and some types of investments.

Tax deductions are subtracted from a person’s total taxable income. After deductions, taxes are paid on the amount of taxable income that remains. Eligible deductions can allow qualifying individuals to reduce their overall tax liability to the Internal Revenue Service (IRS).

For example, let’s say Person X earns $70,000 per year. They qualify for a total of $10,000 in income tax deductions. When calculating their income tax liability, the allowable deductions would be subtracted from their income — leaving $60,000 in taxable income. Person X then would need to pay income taxes on the remaining $60,000 — not the $70,000 in income that they originally earned.

For the 2024 tax year, 22% is the highest federal income tax rate for a person earning $70,000, according to the IRS. By deducting $10,000 from their taxable income, they are able to lower their federal total tax bill by $2,200, which is 22% of the $10,000 deduction. (There may be additional state income tax deductions.)

A tax deduction is not the same as a tax credit. Tax credits provide a dollar-for-dollar reduction on a person’s actual tax bill — not their taxable income. For example, a $3,000 tax credit would eliminate $3,000 in taxes owed.

💡 Quick Tip: The advantage of opening a Roth IRA and a tax-deferred account like a 401(k) or traditional IRA is that by the time you retire, you’ll have tax-free income from your Roth, and taxable income from the tax-deferred account. This can help with tax planning.

Putting the IRA Tax Deduction to Use

Traditional IRA tax deductions are quite simple. If a qualifying individual under age 50 contributes the maximum allowed to a traditional IRA in a year — $7,000 for the 2024 and 2025 tax years — they can deduct the full amount of their contribution from their taxable income.

That said, you are not eligible to claim your IRA deduction if you are:

•   Single and covered by a workplace retirement account and your modified adjusted gross income (MAGI) is more than $87,000 for tax year 2024 ($89,000 or more for tax year 2025)

•   Married filing jointly and covered by a work 401(k) plan and your MAGI is more than $123,000 and less than $143,000 for tax year 2024 (more than $126,000 and less than $146,000 for tax year 2025)

•   Married, only your spouse is covered by a work 401(k) plan, and your MAGI is more than $230,000 and less than $240,000 for tax year 2024 (more than $236,000 and less than $246,000 for tax year 2025).

401(k), 403(b), and other non-Roth workplace retirement plans work in a similar way (when it comes to a Roth IRA vs a traditional IRA, contributions to a Roth IRAs are not tax deductible). For the 2024 tax year, the contribution maximum for a 401(k) is $23,000 with an additional $7,500 catchup contribution for employees 50 and older. For tax year 2025, the contribution maximum is $23,500 with an additional $7,500 catchup contribution for employees 50 and older. Also for 2025, those aged 60 to 63 may contribute an additional $11,250 instead of $7,500, thanks to SECURE 2.0.

Thus, a person under 50 who contributes the full amount in 2024 could then deduct $23,000 from their taxable income ($23,500 in 2025), potentially lowering their tax bracket.

One common source of confusion: The tax deduction for an IRA will reduce the amount a person owes in federal and state income taxes, but will not circumvent payroll taxes, which fund Social Security and Medicare. Also known as Federal Insurance Contributions Act (FICA) taxes, these are assessed on a person’s gross income. Both the employer and the employee pay FICA taxes at a rate of 7.65% each.

Understanding Tax-Deferred Accounts

Traditional IRA, 401(k), and other non-Roth retirement accounts are deemed “tax-deferred.” Money that enters into one of these accounts is deducted from an eligible person’s total income tax bill. In this way, qualifying individuals do not pay income taxes on that invested income until later.

Because these taxes are simply deferred until a later time, the money in the account is usually taxed when it’s withdrawn.

Here’s an example of this: Having reached retirement age, a person chooses to withdraw $30,000 per year from a traditional IRA plan. As far as the IRS is concerned, this withdrawal is taxable income. The traditional IRA money will be taxed as the income.

So, what’s the point of deferring taxes? Generally speaking, people may be in a higher marginal tax bracket as a working person than they are as a retired person. Therefore, the idea is to defer taxes until a time when an individual may pay proportionally less in taxes.

Tax Brackets and IRA Deductions

Income tax brackets can work in a stair-step fashion. Each bracket reveals what a person owes at that level of income. Still, when a person is “in” a certain tax bracket, they do not pay that tax rate on their entire income.

For instance, in 2024, single filers pay a 12% federal income tax rate for the income earned between $11,601 and $47,150. Then, the tax rate “steps up,” and they pay a 22% tax on the income earned that falls in the range of $47,151 and $100,525. Even if a person is a high-earner and “in” the 37% tax bracket, they still pay the lower rates on their lower levels of income.

401(k) Withdrawals and Taxation

Now, let’s compare that with the taxation on a $30,000 withdrawal from a 401(k). Assuming 2024 income tax rates, a $12,000 withdrawal would be taxed at a 10% rate up to $11,600 and then a 12% rate for the remaining $18,400.

Taxes are assessed at a person’s “effective,” or average, tax rate. This is another reason that some folks prefer to defer their taxes until later, when they can pay a hypothetically lower effective tax rate on their withdrawals, rather than taxes at their highest marginal rate.

But, here’s why it’s not so simple: All of the above assumes that income tax rates remain the same over time. And, income tax rates (and eligible deductions) can change with federal legislation.

Still, plenty of earners opt to reduce their tax bill at their highest rate in the current year — and a tax deduction via an eligible retirement contribution can do just that.

For individual tax questions, it’s a good idea to consult a tax professional with questions about specific scenarios.

What About Roth IRAs and Taxes?

Simply put, there are no tax deductions for Roth retirement accounts. Both Roth IRA and Roth 401(k) account contributions are not tax-deductible.

The trade-off is that Roth money is not taxed when it is withdrawn in retirement, as is the case with tax-deferred accounts like a 401(k) and traditional IRA. In fact, this is the primary difference between Roth and non-Roth retirement accounts. With Roth accounts, taxes are already paid on money that is contributed, whereas income taxes on a non-Roth 401k are deferred until later.

So, then, what are some advantages of a Roth retirement account? All retirement accounts provide an additional type of tax benefit as compared to a non-retirement investment account: There are no taxes on interest or capital gains, which is money earned via the sale of an investment.

Someone might choose a Roth over a tax-deferred retirement account because they prefer to pay the income taxes up front, instead of in retirement. For example, imagine a person who earned $30,000 this year. They pay a relatively low income tax rate, so they simply may prefer to pay the income taxes now. That way, the taxes are potentially less of a burden come retirement age.

Not everyone qualifies for a Roth IRA. There are limits to how much a person can earn. For a single filer, the ability to contribute to a Roth IRA for tax year 2024 begins to phase out when a person earns more than $146,00 ($150,000 for tax year 2025), and is completely phased out at an income level of $161,000 in 2024 ($165,000 for tax year 2025). For a person that is married and filing jointly, the phase-out begins at $230,000 in 2024 ($236,000 for tax year 2025), ending at $240,000 in 2024 ($246,000 for 2025).

Investing for Retirement

Different types of retirement accounts come with distinct tax benefits and, for eligible investors, IRA tax deductions. Opening a retirement account and contributing to certain tax-deferred accounts may affect how much a person owes in income taxes in a given year. Roth accounts may provide tax-free withdrawals later on.
