The account that travels with you
A 401(k) depends on your employer offering one. An IRA depends on nobody. Any person with earned income can open an individual retirement arrangement at almost any broker in about ten minutes, fund it, and get the same core deal: investments that grow without an annual tax bill.
For 2026, the IRS set the contribution limit at $7,500, plus a $1,100 catch-up if you are 50 or older. That limit is shared across all your IRAs, traditional and Roth together. It is smaller than the 401(k)‘s $24,500, but the IRA makes up for it with freedom: you pick the broker, you pick from the whole market of funds instead of an employer’s menu, and you keep the account through every job change of your career.
If your employer offers no retirement plan, the IRA is not one option among several. It is the plan.
It is also the account your old 401(k)s eventually flow into. Every job change leaves a plan balance behind, and rolling those orphans into one IRA puts your whole retirement picture on a single statement, under fund choices you control, at fees you picked. Done as a direct rollover, the move costs nothing and triggers no tax.
How the tax break works
A traditional IRA’s pitch is a deduction today. Contribute $7,500, and if you qualify, your taxable income drops by $7,500 this year. The money then compounds untaxed for decades, and you pay income tax when you withdraw it in retirement.
Here is the catch, and it is the part the brokerage ads skip: the deduction is not universal. If neither you nor your spouse is covered by a retirement plan at work, you can deduct the full contribution at any income. If you are covered by a workplace plan, the IRS phases out the deduction. For 2026, the phase-out runs from $81,000 to $91,000 of modified adjusted gross income for single filers, and from $129,000 to $149,000 for married couples filing jointly when the contributing spouse is covered. A non-covered spouse married to a covered one phases out between $242,000 and $252,000.
Above those ranges you can still contribute, but without the deduction. At that point a Roth IRA, if your income allows one, is usually the better home for the same dollars, because nondeductible traditional contributions buy you tax-deferred growth and a paperwork obligation rather than a real tax break.
The strings attached
The deal has two enforcement mechanisms, and you should know both before funding the account.
First, the early withdrawal toll. Take money out before age 59 and a half and you generally owe income tax plus a 10% additional tax. The IRS lists exceptions, but the design is deliberate: this is one-way money headed for retirement.
Second, required minimum distributions. Starting at age 73, the IRS makes you withdraw a calculated amount each year and pay the deferred tax, whether you need the income or not. The traditional IRA is a deal with a maturity date, not a tax shelter forever.
Neither string is a reason to skip the account. Both are reasons to fund it with money you genuinely will not need until retirement, which is a budgeting question before it is an investing question.
Where the IRA fits, and what comes first
The standard order of operations: capture any employer 401(k) match first, because matched dollars are an instant return no IRA can offer. Then fund the IRA, where your investment choices are broader and often cheaper than a plan menu. Then return to the 401(k) for anything beyond that. Our 401(k) vs. IRA comparison walks the full sequence.
Inside the IRA, boring wins: a broad, low-cost index fund or a target-date fund, bought automatically every month. The account is the tax wrapper. The discipline is the engine.
Before any of it, check the foundation. An IRA contribution you have to claw back during an emergency is worse than no contribution, because early withdrawals get taxed and penalized on the way out. Keep three to six months of expenses in a high-yield savings account first, where the money earns real interest and stays reachable. Cash cushion, then match, then IRA. Run that order every year and the retirement math mostly takes care of itself.
