Retirement Planning for Business Owners: Plan Options That Work

Executive Summary

• Retirement planning for business owners starts with matching a plan to your entity structure and headcount, not chasing the largest headline contribution limit.
• A traditional or Roth IRA may be the best starting point for someone just beginning as a small business owner.
• SEP IRAs and Solo 401(k)s are two of the most popular choices for self-employed individuals and owners with no employees beyond a spouse.
• An owner-only 401(k) allows contributions as both employee and employer, which can move more money into tax-advantaged accounts.
• Profitable owners can use defined benefit plans to turn excess profit into tax-advantaged retirement income.
• High-income owners often combine two plan types to shelter $300,000 or more per year, and plans can also support hiring and retention goals.

Why Retirement Planning Looks Different for Owners

An employee waits for an employer to sponsor a plan and decide the match. A business owner is the employer, the participant, and the one deciding how much profit goes toward the future. There is no default, and there is no automatic contribution coming out of someone else’s payroll system.

The result shows up in the data. A May 2025 survey reported that one in five small business owners had no retirement savings at all, and most who did save were behind where they wanted to be. That is not a discipline problem. It is a structural one. Business income arrives unevenly, capital needs compete with personal goals, and the business itself starts to feel like the retirement plan.

That last assumption is the risky one. A business can absolutely fund a retirement, but usually through a deliberate event such as a sale or a structured transition. Counting on it without a plan around it leaves the outcome to timing and market conditions you do not control.

 

The Main Retirement Plan Options for Owners

Most owner-focused retirement plans fall into a handful of categories. The right fit depends on whether you have employees, how much profit you expect, and how much you want to contribute in a strong year.

Traditional or Roth IRA

For someone just starting out as a small business owner, a traditional or Roth IRA may be the best bet. Contribution limits are modest compared with employer plans, but the account is simple to open and simple to maintain. It also keeps the habit of annual saving in place while the business finds its footing.

SEP IRA

A SEP IRA and a Solo 401(k) are two popular options for small business owners and self-employed individuals, and both offer tax advantages. The SEP IRA leans toward simplicity, which suits owners who want a low-maintenance structure and predictable administrative overhead. It can work well when income fluctuates, because funding can be adjusted year to year.

Solo 401(k) and Owner-Only 401(k)

A Solo 401(k) is designed for self-employed individuals and business owners with no employees other than a spouse. Because the owner wears two hats, the structure allows contributions as both employee and employer, which is how it can outpace other plans at similar income levels. An owner-only 401(k) follows the same logic for someone running a business as the sole employee.

Defined Benefit Plans

Profitable business owners can use defined benefit plans to convert excess profit into tax-advantaged retirement income. These plans are built around a target benefit rather than a fixed annual contribution, which is why they tend to attract owners with strong, steady profits and a short runway to retirement. They involve more administration and actuarial work than a 401(k), so they suit owners who want to move larger amounts and are prepared for the upkeep.

Comparing Plan Types at a Glance

Plan type	Typical fit	What stands out
Traditional or Roth IRA	Owners just starting out	Simple entry point for annual saving
SEP IRA	Small business owners and self-employed individuals	Tax advantages with a straightforward structure
Solo 401(k) or owner-only 401(k)	Owner-only businesses, sometimes including a spouse	Contributions as both employee and employer
Defined benefit plan	Profitable owners with excess profit	Turns excess profit into tax-advantaged retirement income

How High-Income Business Owners Reduce Current Taxes

Sheltering $300,000 per year typically requires combining two types of retirement plans. The first is a defined contribution plan, often a 401(k) paired with a profit-sharing feature. The second layers on top of it, which is what lifts the total well beyond what a single plan allows.

A defined benefit plan is the common partner in that pairing. While a 401(k) with profit sharing is capped by contribution limits tied to compensation, a defined benefit plan is designed around the retirement income you want to reach. When profit is strong and the timeline is short, that combination lets an owner move a much larger share of business income into a tax-advantaged structure.

The tradeoff is complexity and cost. Two plans mean two sets of administration, testing, and reporting obligations, and the funding commitment is easier to justify in a high-profit year than a lean one. This is a structure to size carefully against realistic revenue rather than a template to copy from another business.

 

Non-Plan Strategies That Belong in the Conversation

Retirement funding does not stop at qualified plans. Owners have several other levers, and each one interacts with the others.

• An estate freeze, which addresses how future business value is treated across generations.
• The eventual sale of the business, which is often the single largest retirement asset an owner holds.
• Investing through the business, using company capital rather than personal after-tax dollars.
• Holding company or family entity structures that reorganize how assets and income are held.

Each of these depends on entity type, ownership structure, and personal goals, so treat them as questions to raise in a planning conversation rather than one-size-fits-all moves. They also take time to set up properly. The owners who get the most from them tend to start years before they plan to step back, not in the final year before a sale.

How a Retirement Plan Supports Business Goals

Retirement plans have long been treated as an effective tool for companies looking to improve recruitment and retention. For owners with staff, a plan is part of the compensation story that helps keep key people in place. That benefit is separate from the owner’s own savings, but the two decisions are made together, since plan design drives what the owner can contribute as well.

For owner-only businesses, the recruitment angle disappears and the tax angle takes over. The same structure that supports a team can be the vehicle that lets a solo owner defer a meaningful share of profit.

 

Building a Retirement Planning Strategy for Business Owners

1. Start with the retirement income you actually need, then work backward to a funding target. The plan choice follows the target, not the other way around.
2. Match the structure to headcount. Owner-only situations open doors that close once you hire non-spouse employees.
3. Size contributions against profit, not gross revenue. A commitment that fits a peak year can strain the business in a slow one.
4. Check whether a second plan makes sense if profit is consistently high. Combining a defined contribution plan with a defined benefit plan is how the largest annual deferrals happen.
5. Revisit the plan every year. Profit changes, entity structures change, and the plan that fit three years ago may cap you today.

Turning Business Success Into Retirement Income

Retirement planning for business owners comes down to three decisions: which plan structure fits your business today, how much profit you can commit without starving operations, and how the business itself converts into retirement income when you step back. Get those right and the business becomes a funding engine rather than a substitute for a plan.

Frequently Asked Questions

What is the best retirement plan for a business owner?

There is no single best retirement plan for every business owner. The right choice depends on your income, business structure, number of employees, retirement timeline, and tax goals. For some owners, a SEP IRA or Solo 401(k) may be sufficient, while higher-income business owners may benefit from combining a defined contribution plan with a defined benefit plan.

Is a SEP IRA or a Solo 401(k) better for a one-person business?

Both are popular options for small business owners and self-employed individuals, and both offer tax advantages. The Solo 401(k) allows contributions as employee and employer and can include a spouse who works in the business, which often allows more to be sheltered. The SEP IRA is simpler to administer. The better answer depends on your income, entity type, and how much you want to defer each year.

How much can a business owner contribute to retirement plans annually?

It depends on the plan. A single plan is capped by limits tied to compensation, which is why owners with high profit often combine two types of plans. Pairing a defined contribution plan, typically a 401(k) with profit sharing, with a defined benefit plan can let a profitable owner shelter $300,000 or more per year. Your own figure depends on your numbers.

I am just starting my business. Where should I begin?

If you are just starting out as a small business owner, a traditional or Roth IRA may be your best bet. Limits are lower than employer plans, but the account is easy to open and keeps annual saving going while cash flow stabilizes. Once profit is consistent, you can move up to a SEP IRA, a Solo 401(k), or a combined structure.

Can my retirement plan help me keep good employees?

Retirement plans have long been seen as an effective tool for improving recruitment and retention. A plan strengthens the overall compensation package, which matters most for key roles you cannot easily replace. Just keep in mind that adding employees changes which plan designs and contribution levels are available to you as the owner, so the two decisions should be made together.

Is my business itself enough to fund retirement?

A business can fund retirement, but normally through a deliberate event such as a sale or a structured transition rather than by simply existing. Owners also have other levers, including an estate freeze, investing through the business, and holding company or family entity structures. Because these depend on your entity type and goals, they are best reviewed well before you plan to step back.
