From W-2 to Self-Employed: How Retirement Planning Changes

As an employee, your retirement decisions may have been relatively simple. Your employer chose the retirement plan, typically a 401(k), and you decided how much to contribute. Your employer may also have provided a match.

Once you become self-employed, you have more control, but also more decisions.

You need to determine:

• What to do with your old employer 401(k)
• Which retirement plan to establish for your business
• How your business structure affects your contribution
• How much money you actually want to put into retirement accounts

The goal should not necessarily be to maximize every available retirement contribution. Your retirement strategy now has to compete with other priorities such as business investment, taxes, cash reserves, and personal liquidity.

Here is how to think through the transition.

1. What Happens to Your Old 401(k)?

Leaving your employer does not mean you have to immediately move your old 401(k).

Depending on the plan, you may be able to leave the assets where they are.

Another common option is to roll the account into a traditional IRA. A properly structured direct rollover generally allows pre-tax retirement assets to move from an employer retirement plan into a traditional IRA without creating current taxable income.

A rollover IRA can provide several benefits.

You may have a broader range of investments than you had inside your employer's plan. You can also consolidate old retirement accounts and have more control over where the assets are held.

But rolling your old 401(k) into an IRA should not necessarily be automatic.

For example, holding substantial pre-tax assets in traditional, SEP, or SIMPLE IRAs can affect the tax calculation for someone using a backdoor Roth IRA strategy.

Your previous employer's plan may also have attractive institutional investment options or fees.

And if you establish a retirement plan for your new business, that plan may eventually be another possible destination for eligible retirement assets.

So before moving an old 401(k), consider how that account fits into your broader retirement strategy.

2. Two Common Retirement Plans for Solo Business Owners

There are several retirement plans available to business owners.

For someone leaving corporate employment and starting a business without employees, two of the most common options to evaluate are a Solo 401(k) and a SEP IRA.

Solo 401(k)

A Solo 401(k), also called a one-participant 401(k), is generally designed for a business owner with no employees other than potentially the owner's spouse.

The important difference from a corporate 401(k) is that, as the business owner, you can contribute in two capacities:

• As the employee, through elective deferrals.
• As the employer, through employer contributions.

For 2026, the employee elective-deferral limit is $24,500. The overall defined-contribution limit is $72,000 before applicable catch-up contributions, although your actual contribution will depend on your compensation and the applicable plan rules.

This employee-plus-employer structure can make a Solo 401(k) particularly useful for a profitable owner-only business.

SEP IRA

A SEP IRA works differently.

The contribution is made by the employer. Unlike a traditional 401(k), a SEP IRA does not provide a separate employee salary-deferral contribution.

For 2026, SEP contributions are generally limited to the lesser of 25% of eligible compensation or $72,000, subject to special calculations for self-employed individuals.

A SEP IRA can be relatively straightforward to establish and administer.

However, the best choice between a Solo 401(k) and SEP IRA depends on your income, desired contribution level, business structure, and how much flexibility you want from the plan.

The advertised maximum contribution should not be the only consideration.

3. Your Business Structure Affects Your Retirement Contribution

Once you become self-employed, your business structure can directly influence how retirement contributions are calculated.

This is an important change from being a traditional employee.

Sole Proprietorship

Suppose you begin consulting as a sole proprietor.

Your retirement-plan contribution is generally based on your net earnings from self-employment, not your gross business revenue.

For a self-employed individual, the calculation requires adjustments to business earnings. Net earnings are generally reduced by the deductible portion of self-employment tax and by the retirement-plan contribution itself when determining plan compensation.

That means you cannot simply take your Schedule C profit and multiply it by the stated employer contribution percentage.

For example, if your consulting business generates $200,000 of net Schedule C profit, the calculation for the employer portion of a Solo 401(k) or SEP IRA requires additional adjustments.

Single-Member LLC

Forming an LLC by itself does not necessarily change the retirement contribution calculation.

A single-member LLC that has not elected a different tax classification is generally taxed as a sole proprietorship for federal tax purposes.

That means its retirement contribution calculation generally follows the same self-employed rules.

S Corporation

The calculation changes if your company is taxed as an S corporation.

An S-corporation owner who works for the business generally receives W-2 compensation.

Retirement-plan contributions are based on that W-2 compensation.

S-corporation distributions do not count as earned income for retirement-plan contribution purposes.

Consider a simplified example.

Suppose your S corporation generates $300,000 of income and you pay yourself $120,000 of W-2 wages.

Your employer retirement contribution is generally based on the $120,000 of W-2 compensation, not the entire $300,000 of business income.

That creates an important planning trade-off.

Business owners sometimes focus on minimizing W-2 wages in order to reduce payroll taxes, subject to the requirement to pay reasonable compensation.

But lowering W-2 compensation can also reduce the compensation available for retirement-plan contributions.

Retirement planning therefore becomes another factor to consider when determining compensation.

4. How Much Should You Actually Contribute?

Once you determine how much you can contribute, the more important question may be how much you should contribute.

For an employee with a predictable paycheck, maximizing a workplace 401(k) may be relatively straightforward.

For an entrepreneur, the answer can be different.

Liquidity Becomes More Important

Entrepreneurial income is often less predictable than W-2 income.

Your cash may need to cover:

• Business operating expenses
• Estimated tax payments
• Hiring
• Technology and marketing
• Professional services
• Personal living expenses during slower periods
• Unexpected business opportunities

Money contributed to retirement accounts generally becomes less accessible than money held in cash or taxable investments.

So maximizing your retirement plan while leaving yourself short of operating cash may not be the best trade-off.

A larger cash reserve can have significant value when your income is less predictable.

5. Retirement Contributions Can Become More Flexible

One advantage of owning the business is that your retirement contribution strategy does not necessarily have to look the same every year.

Suppose your business earns $100,000 in its first year.

You may prefer to preserve liquidity while the business is still developing.

Several years later, the same business may generate $400,000.

At that point, a substantially larger retirement contribution may make more sense.

You can think about retirement saving alongside the economic cycle of your business rather than automatically contributing the same percentage every year.

6. Consider Your Current Tax Rate

The value of a pre-tax retirement contribution depends partly on the tax rate at which you receive the deduction.

Someone leaving a highly compensated corporate role may experience a temporary decline in taxable income while building a new business.

If your current marginal tax rate is significantly lower than it was during your W-2 years, the value of an additional deduction may also be lower.

As the business becomes more profitable and your income rises, larger pre-tax contributions may become more valuable.

That does not mean you should avoid retirement contributions during lower-income years.

It means the decision between pre-tax savings, Roth savings, and preserving liquidity should be considered in the context of your broader tax picture.

7. Think About the Opportunity Cost of the Money

Retirement accounts are only one possible destination for excess cash.

As an entrepreneur, the same dollar could potentially be used to:

• Reinvest in the business
• Maintain additional cash reserves
• Invest through a taxable brokerage account
• Purchase real estate
• Pay down debt
• Save toward another financial goal

The right answer depends on what the alternative use of that capital is.

For example, contributing an additional $30,000 to a retirement account may generate an attractive current tax deduction.

But if that same $30,000 would prevent you from having to borrow money to fund your business six months later, preserving liquidity could be more valuable.
