Retirement Planning for Solopreneurs

Retirement planning for solopreneurs is the process of converting business income into personal assets capable of supporting future living expenses.

Unlike many employees, solopreneurs must design their own system. There may be no automatic workplace enrollment, employer match, pension department, paid sick leave, or benefits team checking whether contributions happen.

The plan must also accommodate irregular income, changing tax liabilities, and the possibility that the business cannot be sold when the owner wants to stop working.

Why retirement planning is different for solopreneurs

Solopreneurs face several connected challenges:

• Income may change substantially from month to month.
• Retirement contributions are easy to postpone during slow periods.
• Much of the owner’s wealth may remain inside the business.
• The owner may lack an employer contribution or pension.
• Business and personal risks are concentrated in the same person.
• Illness can reduce current income and future retirement funding simultaneously.
• A business sale may depend on the owner’s continued involvement.
• Tax-advantaged account rules can be more complicated for self-employed people.
• Hiring an employee can change retirement-plan obligations.

The flexibility of self-employment is valuable, but flexibility without a contribution rule often results in inconsistent saving.

Current data illustrates the broader retirement gap. According to Federal Reserve data, only 35% of non-retired US adults believed their retirement savings plan was on track in 2025. Although 67% of adults had some asset specifically designated for retirement income, 53% said they were not comfortable or only slightly comfortable choosing and managing investments.

Build retirement on four income sources

A resilient retirement plan can combine four layers:

Do not assume every layer must be equally large. Public benefits may cover a substantial share of essential spending in one country and very little in another.

The important distinction is between income you can reasonably rely on and income that remains uncertain.

Do not make the business your entire retirement plan

A business can be a valuable asset, but it is usually concentrated, illiquid, and difficult to value.

Its sale price can depend on:

• Revenue stability
• Customer concentration
• Transferable contracts
• Documented systems
• Intellectual property ownership
• Dependence on the owner’s identity
• Platform and traffic risk
• Profitability after replacing the owner
• Market conditions at the time of sale
• Availability of qualified buyers
• Taxes and transaction costs

A personal brand, freelance practice, or consulting business may generate excellent income while having limited value without its owner.

Use one of these approaches:

• Assign no sale value in the base retirement plan.
• Include only a conservative after-tax value supported by market evidence.
• Treat estimated sale proceeds as optional protection or legacy capital.
• Update the estimate when the business becomes more transferable.

This prevents retirement security from depending on one transaction occurring at the right time and price.

Estimate retirement spending

Begin with future spending rather than an arbitrary savings target.

Estimated retirement spending = Current annual spending − Costs expected to end + New retirement costs + Additional healthcare costs + Expected taxes

Costs that may decrease include:

• Business commuting
• Retirement contributions
• Work-related clothing
• Business travel
• Mortgage payments that will be completed

Costs that may increase include:

• Healthcare
• Long-term care
• Home assistance
• Travel and leisure
• Insurance
• Property maintenance
• Support for family members

Calculate spending in today’s purchasing power. This allows you to use inflation-adjusted investment assumptions elsewhere in the plan.

Separate essential and flexible spending

Divide the retirement budget into two categories.

Essential spending

Essential spending includes housing, food, utilities, insurance, healthcare, taxes, and basic transportation.

Where possible, essential spending should be supported by reliable income such as:

• Public pension benefits
• Defined-benefit pensions
• Contracted annuity income
• Conservative portfolio withdrawals
• Stable rental or licensing income

Flexible spending

Flexible spending includes travel, gifts, hobbies, upgrades, and discretionary purchases.

This portion can adjust after weak investment years without threatening the owner’s basic standard of living.

Spending flexibility matters because a retirement portfolio is most vulnerable when withdrawals remain high during poor early market returns.

Calculate the retirement income gap

Subtract reliable retirement income from expected annual spending:

Annual portfolio gap = Retirement spending -Reliable annual income

Suppose expected retirement spending is $60,000 and public or pension income is $18,000:

$60,000-$18,000 = $42,000

The investment portfolio must initially provide approximately $42,000 per year.

Do not subtract uncertain consulting, business-sale, or royalty income unless the base plan can justify relying on it.

Estimate the required portfolio

A simplified portfolio target is:

Required portfolio = Annual portfolio gap ÷ Planning withdrawal rate

Using an annual gap of $42,000:

These are planning scenarios, not guarantees.

Current Morningstar research estimated a 3.9% starting rate for fixed inflation-adjusted withdrawals over 30 years, using a 90% probability of funds remaining and excluding public benefits. The result depends on its return, inflation, asset-allocation, and time-horizon assumptions; it is not a universal withdrawal prescription.

A longer retirement, inflexible spending, high fees, uncertain public benefits, or a desire to leave assets behind may justify using a lower planning rate. Flexible spending and substantial guaranteed income may support a different approach.

Calculate how much to contribute

If the portfolio target, current balance, years remaining, and assumed real return are known, an illustrative annual contribution can be estimated:

Required annual contribution (C) = [Target portfolio − Current balance × (1 + real return)^years] × real return ÷ [(1 + real return)^years − 1]

Where:

• (C) = required annual contribution
• (T) = target portfolio
• (B) = current retirement balance
• (r) = assumed annual real return
• (n) = years until retirement

Suppose:

• Target portfolio: $1,000,000 in today’s money
• Current portfolio: $100,000
• Time remaining: 20 years
• Assumed real return: 4%

The result is approximately:

C = $26,200 per year

That equals roughly $2,185 per month.

This is a projection, not an expected result. Test lower returns, higher spending, an earlier retirement, and periods without contributions.

Use an irregular-income contribution system

A fixed monthly contribution alone may not suit a business with seasonal or project-based income. Use a three-part system instead.

1. Base contribution

Contribute a manageable minimum every month, including during ordinary slow periods.

Monthly base contribution = Conservative monthly income × Base savings rate

The base contribution preserves the habit and keeps retirement from becoming an annual afterthought.

2. Percentage contribution

Apply a chosen percentage whenever the owner pays themselves or receives distributable profit:

Contribution = Eligible owner income × Retirement percentage

The percentage should be determined from the retirement gap rather than copied from a generic rule.

3. Quarterly true-up

At the end of each quarter, compare actual contributions with the year-to-date target:

True-up contribution = Year-to-date target -Contributions already made

If the year was stronger than expected, the true-up captures part of the surplus. If income was weaker, the calculation reveals the shortfall early enough to adjust.

Establish contribution priorities

A practical contribution order is:

1. Meet current living and essential business obligations.
2. Maintain required short-term reserves.
3. Make the planned base retirement contribution.
4. Capture any available employer or government incentive.
5. Use suitable tax-advantaged account capacity.
6. Invest additional long-term savings through flexible accounts.
7. Increase contributions after unusually profitable periods.

This is a planning hierarchy, not a tax rule. Debt costs, account restrictions, public benefits, and local regulation may change the appropriate order.

Retirement money should not repeatedly be withdrawn to cover ordinary business expenses. If that occurs, the business contribution rate, reserves, or operating structure needs correction.

Choose the right retirement account

Account names and tax treatment vary by country, but compare every option using the same criteria:

A larger tax deduction does not automatically make an account better. Fees, investment restrictions, future tax rates, withdrawal flexibility, and administrative work also matter.

US retirement accounts for solopreneurs

The following section provides current US examples. Other countries have different accounts, allowances, deadlines, and tax treatment.

Traditional or Roth IRA

An IRA is individually owned and does not require the business to sponsor a plan.

For 2026, the standard combined traditional and Roth IRA contribution limit is $7,500. People aged 50 or older can make an additional $1,100 catch-up contribution.

Traditional IRA deductions and Roth IRA eligibility can be restricted by income, filing status, and workplace-plan coverage.

One-participant 401(k)

A one-participant 401(k), commonly called a solo 401(k), generally covers a business owner with no common-law employees or the owner and their spouse.

The owner can contribute in two capacities:

• As an employee through elective deferrals
• As the employer through employer contributions

For 2026:

• Employee elective-deferral limit: $24,500
• General age-50 catch-up: $8,000
• Catch-up for ages 60–63: $11,250
• Overall defined-contribution limit: $72,000, excluding eligible catch-ups and subject to compensation limits

The $24,500 employee-deferral limit is generally shared across the person’s eligible workplace plans, not multiplied by opening several 401(k) accounts.

The one-participant rules also require special calculations for self-employed income. Plans with at least $250,000 in assets generally have an annual Form 5500-EZ filing requirement. Hiring eligible employees can remove the plan’s one-participant advantage and create additional obligations.

SEP-IRA

A SEP-IRA accepts employer contributions and can be comparatively simple to administer.

The 2026 maximum is the lesser of:

• 25% of eligible employee compensation
• $72,000

A self-employed owner uses a special calculation based on adjusted net earnings. The practical contribution percentage is not simply 25% of Schedule C profit.

A SEP generally requires contributions for eligible employees using the same contribution percentage applied to the owner. This can materially change its cost after hiring.

SIMPLE IRA

A SIMPLE IRA is available to qualifying small employers and combines employee salary reductions with required employer contributions.

For 2026:

• Standard employee contribution limit: $17,000
• General age-50 catch-up: $4,000
• Catch-up for ages 60–63: $5,250

Certain qualifying SIMPLE plans may allow a higher standard contribution limit of $18,100. Employer matching or nonelective contributions are generally required.

Defined-benefit or cash-balance plan

A defined-benefit arrangement promises a future benefit rather than merely accepting contributions up to a standard individual account limit.

It can support larger contributions for some older, consistently profitable owners, but requires:

• Stable cash flow
• Actuarial calculations
• Formal administration
• Continuing funding obligations
• Higher setup and maintenance costs

It is generally unsuitable when income is highly unstable or the owner wants complete contribution flexibility.

The current IRS limits should be verified each year. Contribution calculations, deadlines, employee eligibility, and tax treatment require plan-specific professional advice.

Account choice by business situation

Do not open an account solely because it permits the largest theoretical contribution. The contribution must be affordable, correctly calculated, and compatible with the business’s likely future.

Separate current-tax and future-tax decisions

Retirement accounts often provide one of two broad tax treatments:

Tax-deferred contributions

The contribution may reduce current taxable income, while future withdrawals are generally taxed.

This can be attractive when the current marginal tax rate is expected to be higher than the future withdrawal rate. However, future tax laws and retirement income are uncertain.

After-tax contributions

The owner contributes money after current tax, while qualified future withdrawals may receive favorable treatment.

This can provide tax diversification and may be useful when current taxable income is temporarily low.

A balanced retirement plan may contain both types, plus ordinary taxable investments. That gives the future retiree more control over where withdrawals come from.

Tax deductions are not free returns. They usually change when tax is paid.

Invest retirement assets separately from the business

A solopreneur already has significant exposure to:

• Their own labor
• Their industry
• Their country
• Their customer base
• Their business model
• Their operating currency
• Their primary platforms

Retirement investments should generally avoid reproducing the same concentration.

For example, a software founder whose income and business value depend on technology companies increases concentration by investing the entire retirement portfolio in technology stocks.

A retirement portfolio can diversify across:

• Geographic markets
• Company sizes
• Economic sectors
• Bonds and other fixed-income assets
• Cash or short-term reserves
• Different tax-account types

Diversification cannot prevent losses, but it reduces dependence on one company, industry, country, or economic outcome.

Choose an asset allocation

Asset allocation is the proportion held in growth assets, defensive assets, and cash.

Base it on:

• Years until withdrawals begin
• Expected retirement length
• Public or pension income
• Spending flexibility
• Ability to tolerate losses
• Required return
• Other assets and liabilities
• Health and family obligations
• Currency of future spending

Risk tolerance alone is not sufficient. Someone may feel comfortable with volatility but lack the financial capacity to delay withdrawals after a severe loss.

Document a target allocation and rebalance periodically. Avoid changing the entire portfolio in response to headlines, temporary business conditions, or recent market performance.

Account for investment fees

Fees compound in the opposite direction from returns.

If a portfolio earns a 6% gross return but incurs 1.5% in total annual fees, the investor keeps approximately 4.5% before tax. Over several decades, the difference can materially reduce the final portfolio.

Review:

• Fund expense ratios
• Platform charges
• Advisory fees
• Trading costs
• Plan-administration charges
• Currency-conversion costs
• Insurance-product charges
• Exit or transfer fees

Compare fees in currency and percentage terms. A seemingly small percentage can become expensive as the portfolio grows.

Protect the contribution plan

Retirement projections assume future contributions continue. Protecting the owner’s ability to contribute is therefore part of retirement planning.

Review:

• Health coverage
• Disability or income-protection insurance
• Life insurance where someone depends on the owner’s income
• Professional and business liability coverage
• Legal ownership of intellectual property
• Beneficiary designations
• Powers of attorney
• A will or equivalent estate documents
• Business-continuity instructions
• Access information for accounts and essential systems

The purpose is not to insure every possible loss. It is to prevent one foreseeable event from destroying decades of retirement funding.

Plan for phased retirement

Solopreneurs may be able to reduce work gradually instead of stopping on one date.

A phased plan might include:

• Fewer clients
• Shorter projects
• Advisory-only services
• Licensing intellectual property
• Reduced product support
• Seasonal work
• Limited consulting
• Selling part of the business
• Transferring delivery to another operator

Estimate phased income conservatively:

Portfolio withdrawal need = Retirement spending -Reliable income -Phased-work income

Do not make required work the only factor keeping the plan viable. Health, caregiving, technology changes, and customer demand may make continued work impossible.

The strongest phased-retirement plan makes work optional or allows earnings to support discretionary rather than essential spending.

Measure retirement readiness

Funded ratio

Funded ratio = Current retirement assets ÷ Current portfolio target × 100

If retirement assets equal $400,000 and the estimated target is $1,000,000:

$400,000 ÷ $1,000,000 × 100 = 40%

The plan is approximately 40% funded under its current assumptions.

Retirement contribution rate

Contribution rate = Annual retirement contributions ÷ Defined owner income × 100

Define the denominator consistently. It may be gross owner compensation, adjusted self-employment income, or total household earned income.

Outside-business wealth ratio

Outside-business ratio = Investable assets outside the business ÷ Total investable assets plus estimated business value × 100

A low ratio indicates that retirement security remains highly dependent on the company.

Contribution consistency

Contribution consistency = Months with planned contributions ÷ 12 × 100

A high annual contribution made only after an exceptional December can be less reliable than a repeatable monthly and quarterly system.

Review the plan annually

Complete a structured retirement review once a year:

1. Update current retirement-account balances.
2. Recalculate annual retirement spending.
3. Update expected public and pension benefits.
4. Recalculate the required portfolio.
5. Review the planned retirement date.
6. Compare actual contributions with the annual target.
7. Update tax-account limits and eligibility.
8. Review investment allocation and fees.
9. Rebalance when appropriate.
10. Test lower returns and higher inflation.
11. Test early retirement or interrupted contributions.
12. Review business value separately.
13. Update beneficiaries and legal documents.
14. Set the next year’s base contribution and true-up percentage.

Do not revise long-term return assumptions upward merely because the target appears difficult. Change the controllable variables: contributions, spending, retirement timing, fees, or planned part-time income.

Retirement stress tests

Test at least four scenarios.

Lower investment returns

Reduce the assumed real return and recalculate the required contribution.

Early loss of business income

Model one or two years of reduced contributions before the planned retirement date.

Higher retirement spending

Increase healthcare, housing, or family-support costs.

No business-sale proceeds

Remove the estimated business value entirely.

Also consider:

• Living longer than expected
• Retiring earlier
• High inflation near retirement
• A market decline immediately after retirement
• Reduced public pension benefits
• Currency changes
• Supporting a partner or family member

A plan is more credible when moderate changes in assumptions do not cause complete failure.

Common retirement mistakes

• Waiting for income to become perfectly stable
• Contributing only what remains at year-end
• Treating the business as the entire retirement portfolio
• Confusing tax savings with investment returns
• Ignoring the value of public pension benefits
• Using an arbitrary portfolio target
• Forgetting inflation and taxes
• Keeping retirement investments concentrated in the owner’s industry
• Exceeding contribution limits across multiple plans
• Ignoring employee obligations after hiring
• Paying high fees for unused plan features
• Using optimistic business-sale assumptions
• Assuming work can continue indefinitely
• Withdrawing retirement assets for ordinary business costs
• Failing to update beneficiaries
• Never testing a poor-return scenario

Frequently asked questions

How much should a solopreneur save for retirement?

The amount should be calculated from expected retirement spending, reliable future income, current assets, investment assumptions, and years remaining. A generic percentage may be a starting habit, but it cannot confirm whether the plan is adequately funded.

Should retirement contributions be based on revenue or profit?

Affordability is better connected to owner compensation or eligible profit than gross revenue. A low-margin business cannot safely contribute the same percentage of revenue as a high-margin one. Tax-account calculations may use legally defined compensation or adjusted self-employment income.

What is the best retirement plan for a solopreneur?

There is no universal best plan. A solo 401(k) may offer strong contribution capacity for an owner without employees, while a SEP can provide simpler flexible employer contributions. An IRA may be sufficient at lower income, and a defined-benefit arrangement may suit consistently high income. Country, entity structure, employees, fees, and tax position determine suitability.

Can a solopreneur have an IRA and a solo 401(k)?

In the US, an eligible person can generally contribute to both, but contribution, deduction, and income rules still apply. Employee deferrals must also be coordinated with other workplace plans.

What changes if the business hires an employee?

The employee may become eligible for the business retirement plan. A one-participant 401(k) can become subject to additional participation, testing, contribution, and filing requirements. SEP and SIMPLE plans can also require employer contributions for eligible employees.

Should retirement savings come before reinvesting in the business?

Both may be necessary. Reinvesting everything in the company increases concentration and can leave the owner with no independent retirement assets. Establish a minimum retirement contribution before allocating all remaining capital to growth.

Can the business sale fund retirement?

It can contribute, but relying entirely on a sale is risky. The business may be difficult to transfer, worth less than expected, or unsellable at the desired time. Use a conservative after-tax estimate or exclude it from the base plan.

What if income is too irregular for monthly contributions?

Set a small automatic base amount and add percentage-based contributions whenever owner income is paid. Reconcile the result quarterly against a year-to-date target.

How often should the retirement plan be reviewed?

Review contributions quarterly and complete a full planning review annually. Recalculate sooner after a major income change, relocation, marriage, divorce, inheritance, employee hire, business sale, or change in tax residency.

Is working longer a valid retirement strategy?

It can strengthen the plan by adding contributions and shortening the withdrawal period. However, future work should not be assumed when health, caregiving, industry changes, or customer demand could prevent it.
