Contributing to an IRA lets you grow your retirement savings while paying less in taxes, either now or in the future. For 2026, you can put up to $7,500 into an IRA ($8,600 if you’re 50 or older), and depending on which type you choose, you’ll either reduce your taxable income today or never pay taxes on your investment gains at all. Here’s why that matters and how it plays out in practice.
You Pay Less in Taxes
The single biggest reason to use an IRA instead of a regular investment account is the tax break. There are two flavors, and each one saves you money in a different way.
A traditional IRA gives you a tax deduction upfront. If you contribute $7,500 and you’re in the 22% tax bracket, that’s roughly $1,650 less you owe in federal taxes this year. Your money grows untaxed inside the account, and you pay income tax later when you withdraw it in retirement. The idea is that you’ll likely be in a lower tax bracket by then, so the tax bill will be smaller.
A Roth IRA works in reverse. You don’t get a deduction today, but your investments grow completely tax-free, and qualified withdrawals in retirement are tax-free too. If you invest $7,500 a year for 25 years and your account grows to several hundred thousand dollars, you won’t owe a dime on any of those gains when you pull the money out.
The deduction for traditional IRA contributions does phase out at higher incomes if you or your spouse are covered by a workplace retirement plan like a 401(k). For 2026, single filers covered by a workplace plan start losing the deduction at $81,000 of modified adjusted gross income, and it disappears entirely at $91,000. Married couples filing jointly phase out between $129,000 and $149,000 when the contributing spouse has workplace coverage. If only your spouse has a workplace plan and you don’t, the range is much higher: $242,000 to $252,000.
Your Investments Compound Without a Tax Drag
In a regular brokerage account, you owe taxes every year on dividends, interest, and capital gains distributions, even if you reinvest everything. When you eventually sell an investment for a profit, you owe capital gains tax on top of that. Each of those tax payments chips away at the amount of money that’s left to keep growing.
Inside an IRA, none of that happens. Dividends get reinvested without a tax hit. You can rebalance your portfolio or sell a winning position without triggering a taxable event. Over decades, this difference compounds. A dollar that stays fully invested instead of being partially siphoned off by annual taxes simply has more time and more money working for it. The longer your time horizon, the wider the gap between tax-sheltered growth and taxable growth.
Think of it this way: if your portfolio earns 7% a year and you’re losing roughly 1% of that to taxes each year in a brokerage account, you’re effectively earning 6%. Over 30 years, that 1% annual drag adds up to tens of thousands of dollars in lost growth on even modest contributions.
You Can Access Funds Before Retirement in Some Cases
IRAs are designed for retirement, and withdrawing money before age 59½ generally triggers income tax plus a 10% early withdrawal penalty. But there are notable exceptions that make IRAs more flexible than many people realize.
First-time homebuyers can pull up to $10,000 from an IRA penalty-free to put toward a home purchase. You can also withdraw penalty-free to pay for qualified higher education expenses like tuition for yourself, your spouse, or your children. With a Roth IRA specifically, you can always withdraw your contributions (not the earnings) at any time, for any reason, with no tax or penalty, because you already paid tax on that money before it went in.
These exceptions don’t mean you should treat an IRA as a savings account. Every dollar you pull out is a dollar that stops compounding for your future. But knowing the money isn’t completely locked away can make it easier to commit to contributing in the first place.
It Supplements Your Workplace Plan
If you already contribute to a 401(k) or similar employer plan, an IRA adds another layer of tax-advantaged savings on top of it. Workplace plans and IRAs have separate contribution limits, so maxing out both lets you shelter significantly more money from taxes each year.
An IRA also gives you more control. Most 401(k) plans limit you to a menu of 15 to 30 funds chosen by your employer. An IRA at a brokerage lets you invest in virtually any stock, bond, ETF, or mutual fund on the market. That flexibility can mean lower fees, broader diversification, and a portfolio that better fits your goals.
If your employer doesn’t offer a retirement plan at all, an IRA becomes your primary tax-advantaged savings tool, and the full deduction for traditional IRA contributions is available regardless of your income.
It’s One of the Easiest Ways to Build Wealth
You don’t need a large lump sum to start. Most brokerages let you open an IRA with no minimum balance and set up automatic monthly contributions. Contributing $625 a month gets you to the $7,500 annual limit. Even smaller amounts matter: $200 a month invested over 30 years at a 7% average annual return grows to roughly $227,000, all sheltered from annual taxes.
You have until the federal tax filing deadline (typically April 15) to make IRA contributions for the prior tax year. That means if you realize in March that you have extra cash, you can still make a contribution that counts toward last year’s taxes. It’s one of the few retroactive tax moves available to individual taxpayers.
You Can Leave Tax-Free Money to Heirs
A Roth IRA is one of the most efficient tools for passing wealth to the next generation. Withdrawals of contributions from an inherited Roth IRA are always tax-free for your beneficiaries. Withdrawals of earnings are also tax-free as long as the account has been open for at least five years.
Unlike a traditional IRA, a Roth IRA has no required minimum distributions during the original owner’s lifetime. That means you can let the account grow untouched for decades if you don’t need the money, leaving a larger balance for your heirs. Non-spouse beneficiaries who inherit after 2019 generally must empty the account within 10 years of the owner’s death, but the distributions themselves remain tax-free from a Roth. For a traditional IRA, inherited distributions are taxable income to the beneficiary, which can push heirs into a higher bracket during those 10 years.
Eligible designated beneficiaries, a category that includes surviving spouses, minor children of the account holder, and disabled or chronically ill individuals, may stretch distributions over their own life expectancy instead of following the 10-year rule. For everyone else, the 10-year window applies, making Roth’s tax-free status even more valuable since heirs keep every dollar they withdraw.
