Tax-deferred investments are accounts and contracts that let you postpone federal income tax on your contributions, your earnings, or both until you take the money out, usually in retirement. The main options are traditional IRAs, workplace plans like 401(k), 403(b), and 457(b), and annuity contracts issued by insurance companies. Because nothing is skimmed off each year for taxes, the full balance keeps compounding, which can meaningfully outpace a taxable account holding the same investments over a long horizon.
How Tax Deferral Works
In a regular brokerage account, dividends, interest, and realized gains generate a tax bill every year. A tax-deferred account removes that annual drag. Contributions or earnings grow untouched by federal income tax, and you pay ordinary income tax only when you take a distribution. The money you would have sent to the IRS each April stays invested and earns returns of its own.
Tax deferral is not the same as tax exemption. Roth IRAs and Roth 401(k)s use after-tax dollars going in and let qualified earnings come out tax-free. Traditional tax-deferred accounts work in reverse: a potential deduction now, ordinary income tax later. Which one wins depends on whether your tax rate in retirement will be higher or lower than it is today. Plenty of savers use both as a hedge.
The Main Types of Tax-Deferred Accounts
Traditional IRAs
A traditional IRA is a trust or custodial account held for your exclusive benefit at a bank or other IRS-approved custodian. Your interest in the balance is nonforfeitable from day one, so every dollar you put in, plus what it earns, belongs to you immediately. Contributions must be made in cash, and the account cannot hold life insurance. Within those limits, you can invest in stocks, bonds, mutual funds, ETFs, and certain precious metals that meet IRS fineness standards.
If you contribute more than the annual limit, the IRS imposes a 6% excise tax on the excess for each year it stays in the account. You can avoid the penalty by pulling the excess and any earnings on it before your tax filing deadline, including extensions. Earnings taken out during that correction are taxable and can face the 10% early withdrawal penalty if you’re under 59½.
Employer-Sponsored Plans
401(k) plans cover private-sector workers, 403(b) plans cover public schools, churches, and certain nonprofits, and 457(b) plans cover government and some nonprofit employees. All three let you redirect part of your paycheck into the plan before federal income tax is calculated, lowering your taxable income by whatever you defer.
Employers often match part of what you put in. Your own salary deferrals are always 100% vested immediately, but employer contributions typically come with a vesting schedule. Federal law caps how slowly a defined-contribution plan can vest employer money: either cliff vesting, where you own nothing until three years of service and then jump to 100%, or graded vesting, which climbs 20% a year from year two through year six. Many employers vest faster than the maximum, and some vest immediately. Check the plan’s summary description for the exact terms. Leave before you’re fully vested and the unvested employer portion stays behind.
Tax-Deferred Annuities
An annuity is a contract with an insurance company. During the accumulation phase, earnings compound without triggering annual income tax whether the annuity sits inside or outside a retirement account. When payments begin, an exclusion ratio separates the portion representing your original investment (not taxed again) from the portion representing earnings (taxed as ordinary income).
Annuities carry costs that other tax-deferred accounts usually don’t. Most contracts include a surrender charge period of roughly six to eight years, during which pulling more than a small percentage triggers a fee that often starts around 6% and steps down about a point a year. Mortality and expense charges also reduce your net return. Because of those layered costs, annuities generally make sense after you’ve used lower-cost options first.
2026 Contribution Limits
The IRS adjusts the ceilings each year for inflation. For 2026:
- Traditional and Roth IRAs: $7,500, or $8,600 if you’re 50 or older (an extra $1,100 catch-up).
- 401(k), 403(b), and 457(b) plans: $24,500 in employee deferrals, or $32,500 at age 50 or older with the standard $8,000 catch-up. If you’re between 60 and 63, a “super” catch-up allows $11,250 on top of the base instead of $8,000, for a total of $35,750, but only if your plan has adopted the provision.
- Health savings accounts: $4,400 for self-only coverage and $8,750 for family coverage under a high-deductible health plan. HSAs are technically triple-tax-advantaged, because qualified medical withdrawals are never taxed at all.
The limits apply per person, not per account. Two IRAs still share the same $7,500 (or $8,600) cap between them. The same logic applies across multiple employer plans in a year, though 401(k) and 457(b) limits are tracked separately.
Deducting a Traditional IRA Contribution
Anyone with earned income can contribute to a traditional IRA at any income level. Whether you can deduct the contribution is the separate question. If neither you nor your spouse is covered by a workplace retirement plan, the full deduction is available regardless of income.
Once you or your spouse is an active participant in an employer plan, the deduction phases out by modified adjusted gross income. For 2026, the phase-out begins at $81,000 for single filers and $129,000 for married couples filing jointly. Above those thresholds, the deductible amount shrinks and eventually disappears. Box 13 on your W-2 shows whether your employer has marked you as covered. If your income is too high for a deduction, you can still make nondeductible contributions; you lose the upfront break, but earnings still grow tax-deferred until withdrawal. IRS Publication 590-A has the full deduction tables.
Moving Money Between Accounts
Rolling money from one tax-deferred account to another without a tax bill requires following specific IRS rules. The cleanest route is a direct trustee-to-trustee transfer: your current custodian sends the funds straight to the new one. Nothing is withheld, no check goes through your hands, and the move doesn’t count against any rollover limits.
An indirect rollover is riskier. The custodian pays the distribution to you, and you have 60 days to redeposit the full amount into another qualified account. Miss the deadline and the IRS treats the whole distribution as taxable, with the 10% penalty on top if you’re under 59½. Eligible rollover distributions from employer plans are also subject to mandatory 20% withholding, so to roll over the full balance you’d need to replace that 20% from other funds. The IRS also limits you to one indirect IRA-to-IRA rollover in any 12-month period. Direct transfers have no such cap.
Getting Money Out Before 59½
Withdrawals from a tax-deferred account are generally taxed as ordinary income in the year you take them. Distributions before age 59½ face an additional 10% tax on the taxable portion. The IRS waives the early penalty for distributions due to death, permanent disability, a series of substantially equal periodic payments, certain medical expenses, and several other qualifying events.
If your 401(k) plan allows it, you may qualify for a hardship withdrawal without leaving your job. The IRS recognizes several safe-harbor reasons that automatically count as an immediate and heavy financial need:
- Medical expenses for you, your spouse, dependents, or a beneficiary
- Buying a primary home, excluding mortgage payments
- Tuition and education costs for the next 12 months of postsecondary education
- Preventing eviction or foreclosure on your primary residence
- Funeral expenses for immediate family or a beneficiary
- Certain casualty repairs to your principal residence
Hardship withdrawals are still subject to income tax and typically the 10% early withdrawal penalty. Your plan issues Form 1099-R at year-end to report the distribution and any taxes withheld. If you don’t submit withholding instructions on a distribution, the default federal withholding rate is 10%, which may not cover your actual bracket.
Required Minimum Distributions
You can’t leave money in a tax-deferred account forever. Once you reach age 73, the IRS requires annual withdrawals called required minimum distributions. That age applies to anyone who turns 73 between 2023 and 2032. Starting in 2033, the required beginning age rises to 75. Each year’s amount is your account balance divided by a life expectancy factor from IRS tables.
Miss an RMD and the IRS charges a 25% excise tax on the shortfall. If you catch it and take the corrected distribution within roughly two years, the penalty drops to 10%. Either way, you report the shortfall on Form 5329. Custodians must notify you that an RMD is due, but taking it is on you.
If you’re still working past 73 and don’t own 5% or more of the company, most employer plans let you delay RMDs from that plan until you actually retire. Traditional IRAs get no such exception. RMDs start at 73 regardless of whether you’re still working.
What You Cannot Do With the Account
The IRS treats a tax-deferred account as strictly separate from your personal finances. Prohibited transactions include borrowing from your IRA, selling property to it, pledging it as collateral, or buying property for personal use with its funds. The rules cover “disqualified persons,” which includes you, your spouse, your parents, your children and their spouses, and anyone who manages or advises the account for a fee.
The penalty is severe. If you or a disqualified person engages in a prohibited transaction at any point during the year, the entire IRA is treated as if it distributed all its assets to you on January 1 of that year. You owe income tax on the full fair market value above your basis, plus the 10% early withdrawal penalty if you’re under 59½. One bad transaction can wipe out the account’s tax status.
Certain investments are also off-limits. IRAs cannot hold life insurance contracts or collectibles such as artwork, antiques, gems, stamps, or alcoholic beverages. Some precious metals are allowed, but only if they meet specific purity requirements.
Inherited Accounts
When the owner of a tax-deferred account dies, the rules for the beneficiary depend on who inherits. A surviving spouse has the most flexibility: they can roll the inherited account into their own IRA, delay RMDs until they would otherwise be required, or take distributions over their own life expectancy.
Most other beneficiaries fall under the 10-year rule from the SECURE Act. If you inherit an IRA or employer plan from someone who died in 2020 or later and you’re not an “eligible designated beneficiary,” you must empty the account by the end of the tenth year after the owner’s death. There is no annual minimum along the way, but the balance has to be zero by the deadline.
A small group of eligible designated beneficiaries can still stretch distributions across their own life expectancy: the owner’s spouse, minor children until they reach the age of majority, individuals who are disabled or chronically ill, and beneficiaries who are no more than ten years younger than the deceased owner. Once a minor child reaches adulthood, the 10-year clock starts for them too.
