Traditional IRA: How It Works, Tax Benefits & Withdrawal Rules
How a Traditional IRA Works
You open a Traditional IRA at a brokerage, invest in whatever the account supports — stocks, bonds, ETFs, mutual funds, CDs — and your investments grow tax-deferred. You pay no tax on dividends, capital gains, or interest while they’re inside the account.
If you qualify for the tax deduction, your contributions reduce your taxable income in the year you contribute. You then pay ordinary income tax when you withdraw in retirement. The bet: your tax rate in retirement will be lower than it is today, so deferring gives you a net benefit.
Even if you don’t qualify for the deduction, the tax-deferred growth still beats a taxable account over long time horizons — though a Roth IRA is generally the better choice for non-deductible contributions.
2025 Contribution Limits
| Category | 2025 Limit |
|---|---|
| Under age 50 | $7,000 |
| Age 50 and older | $8,000 |
This limit is shared across all your IRAs — Traditional and Roth combined. You can split contributions between them, but the total can’t exceed $7,000 ($8,000 with catch-up).
Tax Deduction Rules — It Depends on Your Situation
Anyone with earned income can contribute to a Traditional IRA. But whether you can deduct those contributions depends on two factors: whether you (or your spouse) have an employer-sponsored plan like a 401(k), and your income level.
| Scenario | Deduction Available? |
|---|---|
| No employer plan at work | Full deduction at any income level |
| Have employer plan, single, MAGI under $79,000 | Full deduction |
| Have employer plan, single, MAGI $79,000–$89,000 | Partial deduction (phase-out) |
| Have employer plan, single, MAGI above $89,000 | No deduction |
| Have employer plan, married filing jointly, MAGI under $126,000 | Full deduction |
| Have employer plan, married filing jointly, MAGI $126,000–$146,000 | Partial deduction (phase-out) |
| Spouse has employer plan (you don’t), MFJ MAGI under $236,000 | Full deduction |
Withdrawal Rules
| Scenario | Tax Treatment |
|---|---|
| Before age 59½ | Ordinary income tax + 10% early withdrawal penalty |
| After age 59½ | Ordinary income tax only |
| Required Minimum Distributions | Must begin at age 73 (SECURE 2.0) |
There are limited exceptions to the 10% penalty: first-time home purchase (up to $10,000), qualified education expenses, certain medical costs, disability, and substantially equal periodic payments (SEPP / Rule 72(t)). But income tax still applies in every case.
Traditional IRA vs. Other Retirement Accounts
| Feature | Traditional IRA | 401(k) |

| Employer match | Not available | Often available |
| Investment choices | Nearly unlimited | Limited to plan menu |
| Income limits for contribution | None (deduction limits exist) | None |

When a Traditional IRA Makes the Most Sense
The Traditional IRA is strongest in specific scenarios. You’re in a high tax bracket now but expect lower income in retirement — the deduction saves you more today than you’ll pay later. You don’t have a workplace retirement plan, giving you an unrestricted deduction regardless of income. Or you want to do a backdoor Roth conversion and need the Traditional IRA as a pass-through vehicle.
For most younger investors in lower brackets, the Roth IRA is typically the better default choice — paying tax now at a low rate and getting tax-free growth for decades.
Rollover Options
You can roll a Traditional IRA into a 401(k) (if your employer allows it), convert it to a Roth IRA (you’ll owe income tax on the converted amount), or consolidate multiple Traditional IRAs into one for simplicity. A Roth conversion can be powerful if your income dips temporarily — you convert at a low tax rate and enjoy tax-free growth going forward.
Key Takeaways
- Traditional IRA contributions may be tax-deductible, depending on income and employer plan coverage.
- Investments grow tax-deferred — you pay ordinary income tax only on withdrawal.
- 2025 limit: $7,000 ($8,000 if age 50+), shared with Roth IRA contributions.
- RMDs start at age 73 — you must withdraw even if you don’t need the money.
- Best for high earners who expect a lower tax rate in retirement, or as a step in the backdoor Roth strategy.
Frequently Asked Questions
Can I contribute to a Traditional IRA with no earned income?
No — you need earned income (wages, self-employment income, etc.) to contribute. The one exception is a spousal IRA: if you’re married filing jointly and your spouse has earned income, they can fund a Traditional IRA in your name even if you don’t work.
What’s the difference between deductible and non-deductible Traditional IRA contributions?
Deductible contributions lower your taxable income now and are fully taxed on withdrawal. Non-deductible contributions don’t reduce your income today, and only the growth is taxed on withdrawal. You track the non-deductible basis on IRS Form 8606.
Should I convert my Traditional IRA to a Roth?
A Roth conversion makes sense if you’re in a lower tax bracket now than you expect in retirement, if you have a year of unusually low income, or if you want to eliminate future RMDs. You’ll owe tax on the converted amount, so run the numbers or talk to a tax professional.
Is there an age limit for Traditional IRA contributions?
No. Since the SECURE Act of 2019, you can contribute to a Traditional IRA at any age as long as you have earned income. The old rule barring contributions after 70½ no longer applies.
