Qualified Retirement Plans: Limits, Withdrawals, and Rollovers

A retirement plan earns “qualified” status — and the tax breaks that come with it — by meeting a detailed set of federal rules under Internal Revenue Code Section 401(a) and ERISA. The qualified retirement plan rules and requirements cover who has to be included, how much can go in, when money can come out, who is legally responsible for the plan, and what has to be reported each year. Missing any of them can cost the plan its tax-exempt status. For 2026, the employee deferral limit is $24,500, but the dollar caps are only one piece of a much larger compliance picture.¹

Qualified plans come in two forms. Defined contribution plans — 401(k)s, profit-sharing plans, and similar arrangements — give each participant an individual account and put the investment risk on the participant. Defined benefit plans, traditional pensions, promise a specific monthly benefit at retirement, and the employer bears the risk of funding it. The rules below apply to both unless noted.

What Makes a Plan Qualified

Section 401(a) exists to keep plans from becoming tax shelters for owners and executives while excluding rank-and-file workers.² Four requirements do most of the work.

Nondiscrimination Testing

Each year, 401(k) sponsors must run the Actual Deferral Percentage and Actual Contribution Percentage tests, comparing average contribution rates of highly compensated employees against everyone else. When rank-and-file workers save more, highly compensated employees are allowed to defer more; when the gap gets too wide, the plan has to take corrective action.³ For 2026, a highly compensated employee is someone who earned more than $160,000 in the prior year or who owns more than 5% of the business.⁴

Coverage

A sufficient percentage of the employer’s non-highly compensated workforce has to be eligible to participate. A plan that technically exists but covers only a handful of top earners will not pass.

Vesting

Your own contributions are always 100% vested immediately. Employer contributions can follow a schedule, but federal law caps the schedule at either a three-year cliff (0% until year three, then 100%) or a graded schedule that starts at 20% after two years and reaches 100% by year six.⁵ Faster schedules are fine; slower ones disqualify the plan.⁶

Top-Heavy Rules

A plan is top-heavy when more than 60% of its assets belong to key employees, defined for 2026 as officers earning more than $235,000 or owners of more than 5% of the business.⁴ A top-heavy plan has to make a minimum contribution of at least 3% of compensation for all non-key employees, even those who aren’t deferring anything themselves. Small businesses where the owner’s account dwarfs everyone else’s run into this often.

2026 Contribution and Benefit Limits

The IRS adjusts qualified plan dollar limits every year for inflation. For 2026:⁴

Employee elective deferrals to a 401(k), 403(b), or 457 plan: $24,500
Standard catch-up contribution at age 50 and over: $8,000
Enhanced catch-up contribution for ages 60 through 63 (created by SECURE 2.0): $11,250
Total annual additions to a defined contribution plan (employee deferrals plus employer contributions plus forfeitures): the lesser of 100% of compensation or $72,000
Maximum annual benefit from a defined benefit plan: the lesser of 100% of the participant’s average compensation for their highest three consecutive years or $290,000⁷

The enhanced catch-up for ages 60 through 63 is easy to miss. If you fall in that window, your combined deferral limit is $35,750, compared with $32,500 available to someone aged 50 through 59.¹

Starting in 2027, participants who earned more than $150,000 in wages during the prior year will be required to make all catch-up contributions on a Roth (after-tax) basis. Plans can adopt the rule earlier voluntarily, but it becomes mandatory for the 2027 tax year.⁸

Getting Money Out Before Retirement

Plan Loans

Many defined contribution plans let participants borrow from their own accounts. The maximum is the lesser of $50,000 or 50% of your vested balance, with a floor allowing up to $10,000 if your vested balance is between $10,000 and $20,000.⁹

Loans aren’t taxable when you take them out. Miss the repayment schedule, though, and the outstanding balance becomes a deemed distribution, taxed as ordinary income and hit with the 10% early withdrawal penalty if you’re under 59½. Leaving your job can accelerate the problem, because most plans require full repayment shortly after separation.

Hardship Withdrawals

Hardship withdrawals differ from loans because the money isn’t repaid. To qualify, you must have an immediate and heavy financial need, and the amount is limited to what’s necessary to cover it.¹⁰ The IRS recognizes safe-harbor reasons that automatically qualify:

Medical expenses for you, your spouse, dependents, or beneficiary
Costs directly tied to buying your primary residence (not ongoing mortgage payments)
Tuition, fees, and room and board for the next 12 months
Eviction or foreclosure prevention on your primary residence
Funeral expenses for you, your spouse, children, dependents, or beneficiary
Certain repair costs for damage to your primary residence

Hardship withdrawals are subject to income tax and potentially the 10% penalty. Not every plan offers them; the plan document controls.

Early Withdrawal Penalty and Exceptions

Distributions from a qualified plan before age 59½ generally trigger a 10% additional tax on top of regular income tax.¹¹ The penalty is waived in several situations that apply to qualified employer plans:¹²

Death of the participant
Total and permanent disability
Separation from service during or after the year you turn 55 (age 50 for public safety employees)
Substantially equal periodic payments based on life expectancy
QDRO distributions to an alternate payee in a divorce
Unreimbursed medical expenses exceeding 7.5% of adjusted gross income
Qualified birth or adoption expenses
IRS levy on the plan account
Qualified reservist distributions

One common misconception is worth flagging: the first-time homebuyer exception does not apply to 401(k)s or other qualified employer plans. It is available only for IRA distributions. If your Form 1099-R doesn’t reflect an exception you qualify for, file Form 5329 to claim it.¹³

When Withdrawals Become Mandatory

You can’t leave money in a qualified plan indefinitely. Required minimum distributions begin based on your birth year:¹⁴

Born 1951 through 1958: RMDs start at age 73
Born 1960 or later: RMDs start at age 75

SECURE 2.0 set these ages, raising the starting age in two steps.¹⁵ The amount is calculated by dividing your prior year-end account balance by a life expectancy factor from IRS uniform lifetime tables. Each year’s RMD is due by December 31. For your first RMD year only, you can wait until April 1 of the following year, but doing so means two distributions land in the same tax year.

Miss an RMD and the excise tax is 25% of the shortfall.¹⁶ Catch it and correct it within the statutory correction window and the penalty drops to 10%.

Rolling Over a Balance

When you leave a job or retire, you can move a qualified plan balance to an IRA or a new employer’s plan without triggering tax. Two methods exist, and the difference matters.

A direct rollover, also called a trustee-to-trustee transfer, sends the money straight from one plan to another. No taxes are withheld and there is no deadline. This is almost always the better route.

An indirect rollover means the plan pays the distribution to you, and you have 60 days to deposit it into another eligible retirement account. The catch is that your old plan withholds 20% for federal taxes when it sends the check. To complete a full tax-free rollover, you have to make up that 20% from your own pocket and deposit the full original amount.¹⁷ Anything you don’t roll over within 60 days is treated as a taxable distribution, with the 10% penalty on top if you’re under 59½.

The IRS limits you to one indirect IRA-to-IRA rollover per 12-month period. That restriction doesn’t apply to direct rollovers or to rollovers from employer plans into IRAs.

Spousal Rights

Qualified plans carry spousal protections that many participants overlook until a divorce or death forces the issue.

Survivor Annuities

Defined benefit plans, money purchase plans, and certain other qualified plans have to pay married participants in the form of a qualified joint and survivor annuity, so the surviving spouse keeps receiving payments after the participant dies. Waiving the QJSA to take a lump sum or other form requires written consent from both the participant and the spouse, witnessed by a plan representative or notary.¹⁸ If the lump sum value is $5,000 or less, the plan can pay it out without spousal consent. These plans must also provide a qualified preretirement survivor annuity protecting the spouse if the participant dies before retirement age.

QDROs in Divorce

A court can divide qualified plan benefits in a divorce through a Qualified Domestic Relations Order. The QDRO has to identify the participant and each alternate payee (only a spouse, former spouse, child, or dependent qualifies), name each plan it covers, and spell out the amount or percentage assigned along with the payment period.¹⁹ The order cannot require the plan to offer a benefit type it doesn’t already provide or to pay more than the actuarial value of what the participant has earned.

Distributions to an alternate payee under a QDRO are exempt from the 10% early withdrawal penalty, one of the few ways to reach qualified plan money before 59½ without the extra tax.¹²

Fiduciary Duties for Sponsors

Anyone who exercises control over a qualified plan’s management, administration, or assets is an ERISA fiduciary. That usually includes the employer, plan trustees, investment committee members, and whoever selects the plan’s service providers. ERISA defines fiduciary status functionally: the title on your card doesn’t matter; what matters is whether you exercise discretion over the plan.

Fiduciaries owe three core duties. Prudence means acting with the care, skill, and diligence of someone familiar with such matters, and it is judged mostly on process. A thorough, documented investigation that leads to a disappointing investment outcome is defensible; a sloppy process that happens to work out is not.²⁰ Loyalty means every decision has to be made solely in the interest of participants and beneficiaries. Diversification means the portfolio has to be spread to minimize the risk of large losses, and heavy concentration in employer stock is a frequent source of fiduciary litigation.

ERISA also requires every person who handles plan funds to be covered by a fidelity bond of at least 10% of plan assets, with a $1,000 minimum and a $500,000 maximum. Plans holding employer stock or operating as pooled employer plans have a $1,000,000 cap.²¹ The bond protects the plan against fraud or dishonesty and is separate from fiduciary liability insurance, which protects the fiduciary personally.

ERISA and the Code also ban prohibited transactions between the plan and parties in interest — the employer, fiduciaries, or service providers. Selling or leasing property between the plan and a party in interest, lending plan money to a party in interest, or using plan assets for a party’s own benefit all fall inside the prohibition. The tax hit is steep: an initial excise tax of 15% of the amount involved for each year the violation continues, jumping to 100% if the transaction isn’t corrected within the taxable period.²² A breaching fiduciary is also personally liable to restore losses to the plan.

Reporting, Disclosure, and Fixing Mistakes

Plan administrators have to file Form 5500 electronically each year.²³ The deadline is the last day of the seventh month after the plan year ends, which is July 31 for calendar-year plans. A 2½-month extension to October 15 is available by filing Form 5558 before the original due date.²⁴ Which version you file depends on size:

Plans with 100 or more participants: full Form 5500, generally requiring an independent audit
Plans with fewer than 100 participants: simplified Form 5500-SF²⁵
One-participant plans with more than $250,000 in total assets: Form 5500-EZ²⁶

Late filing triggers per-day penalties from both the DOL and the IRS, and a plan only a few months behind can face five-figure penalties.

Participants also have to receive a Summary Plan Description explaining eligibility, benefits, claims procedures, and rights, along with an annual Summary Annual Report summarizing the plan’s financial condition from the Form 5500.²⁷ DOL rules require additional fee disclosures so participants can see the costs tied to their accounts and investment options.

Mistakes happen, and the IRS runs the Employee Plans Compliance Resolution System to let sponsors fix them without losing qualified status. EPCRS has three tiers: self-correction for certain operational failures caught internally, the Voluntary Correction Program for more significant problems found before an audit, and the Audit Closing Agreement Program for errors found by an IRS examiner.²⁸ Using these programs proactively is almost always cheaper than waiting for the IRS to find the problem.²⁹
