Stop Leaving Your Retirement Money on the Table
Nobody told you about this when you went out on your own. Not your accountant. Not the bank. Not the business coach you paid good money to sit across from. They helped you set up the LLC, open the business account, figure out quarterly taxes. All useful things. But not one of them sat you down and said: the moment you became a business owner, the rules about retirement savings changed completely in your favor.
That is the part that gets me every time.
In 2026, a self-employed woman with the right retirement plan in place can put away up to $72,000 in a single year — in tax-advantaged accounts, with every dollar reducing her taxable income. The limit for a regular employee with a corporate 401(k)? $24,500. That gap is not a rounding error. Over ten years of maximum contributions, the difference compounds into a number that changes what retirement actually looks like.
The tools are real. The IRS created them. They are sitting there right now, waiting for you to use them. So let's get into it.
The Advantage Nobody Told You About
The standard story about women and retirement is not a pretty one. We live longer than men. We earn less over our lifetimes. We step out of the workforce to take care of children, parents, and everyone else in between, and every one of those gaps is a gap in retirement savings too. That story is true, and it is frustrating.
But here is what that story leaves out. If you own a business — a sole proprietorship, a single-member LLC, a partnership, an S-corp — you have access to retirement contribution structures that most employees will never see. You can contribute to the same account in two separate capacities: as the employee and as the employer. That dual structure is what makes the bigger numbers possible.
And your income fluctuates? Good. Most entrepreneur retirement plans let you scale contributions way up in strong years and pull back in lean ones without penalties or plan termination requirements. You set the pace. You control the lever. That flexibility is something your corporate counterparts simply do not have, no matter how generous their benefits package looks.
Start with the Foundation: Traditional and Roth IRAs
Before we get into the plans built specifically for business owners, there is a foundation worth covering. Anyone with earned income can contribute to an IRA — traditional or Roth — regardless of what else they have going on. For 2026, that limit is $7,500, or $8,600 if you are 50 or older. That catch-up amount actually increased this year for the first time since 2006, thanks to SECURE 2.0.
The choice between traditional and Roth comes down to one question: when do you want to pay taxes? A traditional IRA lets you deduct your contribution now and pay taxes when you take the money out in retirement. A Roth flips it — you pay taxes now, and every dollar you pull out later is completely tax-free. The IRS lays out the full rules, including income phaseout ranges that affect who can deduct a traditional IRA contribution or contribute directly to a Roth.
For entrepreneurs, both types matter strategically. In a high-revenue year when your taxable income is up, a traditional IRA contribution gives you immediate relief. In a year when income is more modest, a Roth contribution lets you pay taxes at a lower rate and lock in decades of tax-free growth. Neither is wrong. They serve different moments.
Think of the IRA as the floor, not the ceiling. Once it is covered, you build on top of it.
The Solo 401(k): The Biggest Tool in the Box
If you run a business with no employees other than yourself — or a spouse — the Solo 401(k) is the most powerful retirement option available to you. Full stop.
Here is why it works. You contribute as the employee, up to $24,500 for 2026. Then, wearing your employer hat, you can contribute an additional 25% of your net self-employment income on top of that. Add them together and the combined ceiling is $72,000 for the year. If you are 50 or older, standard catch-up contributions bring that to $80,000. And if you happen to be between the ages of 60 and 63, a new SECURE 2.0 provision raises your special catch-up limit even higher — up to $83,250 total.
These are not estimates. These are the IRS-confirmed 2026 limits from Notice 2025-67.
Put a real number on it. Say your net business income after expenses is $120,000 and you are 52. You could contribute $24,500 as the employee, plus $7,500 as the over-50 catch-up, plus 25% of your net earnings as the employer contribution. That is well north of $55,000 in a single year — all of it tax-deductible, all of it growing tax-deferred. On a $70,000 contribution in the 32% tax bracket, you are saving roughly $22,400 in taxes. In one year.
Fidelity, Vanguard, and Charles Schwab all offer Solo 401(k) plans with no account minimums and straightforward online setup. Most also offer Roth options within the plan, loan provisions, and a wide range of investment choices. The one administrative note worth knowing: once your Solo 401(k) balance exceeds $250,000, you file a Form 5500-EZ with the IRS each year. It is a minor step, but mark it in your calendar before you get there.
The SEP-IRA: Almost as Powerful, Half the Headache
The SEP-IRA — Simplified Employee Pension — has the same ceiling as the Solo 401(k)'s combined limit: up to 25% of your net self-employment income or $72,000 for 2026, whichever is less. What it trades for that matching power is elegance. There is no annual filing requirement. No compliance testing. No mandatory contribution in any given year. You open it, fund it when it makes sense, and the rest takes care of itself.
For a woman who is still in the build phase of her business — income is real but inconsistent, and she does not want another administrative obligation — the SEP is often the right call. It is genuinely simple in a way that most financial products are not.
The tradeoff is that the SEP does not allow employee-side contributions, only employer contributions. At lower income levels, that means you can actually save more through a Solo 401(k) than a SEP. But once your income is high enough that 25% gets you close to the $72,000 limit anyway, the SEP becomes increasingly attractive just for the ease.
One thing to know if your business is growing: SEP rules require you to contribute the same percentage of compensation for every eligible employee that you contribute for yourself. That can get expensive fast. If you are planning to hire, talk to a tax professional before you commit to a SEP structure.
The SIMPLE IRA: Built for When You Are Building a Team
Once you have employees — or you are about to — the SIMPLE IRA bridges the gap between the solo plans and a full-scale 401(k). It is designed for businesses with 100 or fewer employees and costs a fraction of what a traditional 401(k) plan requires to administer.
For 2026, employees can defer up to $17,000, with an additional $4,000 catch-up for those 50 and older. As the employer, you have two options: match dollar for dollar up to 3% of each employee's compensation, or make a flat 2% contribution for every eligible employee regardless of whether they contribute themselves.
The mandatory employer contribution is what makes this different from the SEP. Your employees know something is coming to them every year, which makes the SIMPLE a real retention tool, not just a tax strategy. If you have two or three people on your team, you want to offer them something meaningful, but you are not ready to take on the complexity of a full 401(k) plan, the SIMPLE IRA is often exactly the right fit.
The HSA: The Retirement Account Nobody Calls a Retirement Account
This one surprises people every time. A Health Savings Account is technically for healthcare expenses. But for someone who can afford to let it grow untouched, it works like a powerful supplemental retirement account with a tax advantage that does not exist anywhere else in the tax code.
Here is what makes it unique. Contributions are tax-deductible going in. Growth inside the account is completely tax-free. Withdrawals for qualified medical expenses are tax-free coming out at any age. After 65, you can withdraw for any reason — you just pay ordinary income tax on non-medical withdrawals, the same as you would from a traditional IRA. For 2026, the limits are $4,300 for individual coverage and $8,550 for family coverage, plus a $1,000 catch-up starting at 55. Current limits are confirmed on the IRS HSA publication page.
To qualify, you need to be enrolled in an HSA-eligible high-deductible health plan. As a self-employed person buying your own coverage anyway, it is absolutely worth checking whether your plan qualifies.
The strategy that makes the HSA work as a retirement vehicle: pay your medical expenses out of pocket during your working years, invest every dollar you contribute to the HSA, and let it compound untouched. By the time you retire, you have a growing fund specifically dedicated to healthcare costs — which, for women who statistically live longer and use more healthcare in their later years, can be substantial.
What Self-Employment Means for Your Social Security
This is the part that makes a lot of entrepreneurs feel cheated, at least at first. As a self-employed person, you pay the full 15.3% self-employment tax — both the employee share and the employer share. That is more than a salaried worker pays, and it stings, especially in early years when every dollar counts.
But here is the fuller picture. You can deduct half of your self-employment tax as an adjustment to your gross income, which brings the real cost down. More importantly, every dollar of self-employment income you report counts toward your Social Security earnings record. Social Security calculates your benefit based on your highest 35 years of indexed earnings. If you spent years in lower-paying corporate roles before building your business, your self-employment income can actually boost your eventual benefit significantly.
When to claim matters enormously. Benefits are reduced permanently if you start at 62. At your full retirement age — 67 for most women reading this — you receive 100% of your calculated benefit. Wait until 70, and you gain 8% per year in delayed credits. For a woman likely to live well into her eighties, the math on delayed claiming is often compelling.
A Day Job and a Side Business? You Can Stack Both.
This is one of the most underused moves in the whole playbook, and almost nobody talks about it. If you have a full-time job with a 401(k) and self-employment income on the side, you may be able to contribute to retirement plans for both.
The employee contribution limit of $24,500 applies across all 401(k) plans combined — you cannot double it just because you have two accounts. But the employer contribution portion of a Solo 401(k), which is calculated as a percentage of your self-employment income, is separate from anything your day-job employer does. That means you could max your employee deferrals through your employer's plan and still make employer-side contributions to your Solo 401(k) based on what your business earns.
The SEP-IRA is even cleaner in this scenario. SEP contributions are calculated entirely on your self-employment income and do not interact with your employee 401(k) at all. Either way, having two income streams opens up real room to accelerate savings in a way most people with a side business never take advantage of.
So Where Do You Start?
The options can feel like a lot, but the path forward is simpler than it looks once you know your situation.
If you are a solo operator — no employees, just you running your own business — the Solo 401(k) is almost always your best first move. It gives you the highest possible contribution ceiling, the most flexibility, and options like Roth contributions and plan loans that the other solo plans do not offer.
If you want power without the paperwork, the SEP-IRA delivers nearly the same ceiling with almost zero administrative burden. Fund it in good years, skip it in lean ones, and move on with your life.
If you have employees or you are about to bring someone on, look at the SIMPLE IRA before you jump straight to a full 401(k). It is a real benefit for your team at a fraction of the cost and complexity.
If you are enrolled in a high-deductible health plan, open an HSA and fund it to the maximum. Do not touch it if you can avoid it. Let it grow.
And if you have both a paycheck from a day job and income from a business you run on the side, get a tax professional to look at your specific numbers. The stacking opportunity is real and the details matter.
Frequently Asked Questions
Can I have both a Solo 401(k) and a SEP-IRA at the same time?
No. The IRS does not allow you to maintain both a Solo 401(k) and a SEP-IRA for the same business. You choose one. For most self-employed women, the Solo 401(k) comes out ahead because of the higher potential contribution at lower income levels and the added flexibility of Roth options.
What is the 2026 Solo 401(k) contribution limit?
The combined employee-plus-employer limit is $72,000 for 2026. If you are 50 or older, that rises to $80,000 with standard catch-up contributions. If you are between 60 and 63, the SECURE 2.0 special catch-up brings the ceiling to $83,250. All of this is confirmed in IRS Notice 2025-67.
Do my retirement contributions reduce my self-employment tax?
Retirement plan contributions reduce your net income for income tax purposes, but they do not reduce your self-employment tax. That tax is calculated on your gross self-employment earnings before retirement contributions. You can, however, deduct half of your self-employment tax as an income adjustment on your federal return.
What happens if I hire employees after setting up a Solo 401(k)?
The Solo 401(k) is only available to businesses with no full-time employees other than the owner and a spouse. If you hire employees who meet the plan eligibility requirements, you will need to transition to a different structure — a SIMPLE IRA or a traditional 401(k). If you expect to grow your team, keep this in mind before you commit to a Solo 401(k) as your long-term solution.
Can I contribute to a retirement plan if my business had a bad year and I lost money?
Not if there was no net self-employment income. Most employer-sponsored retirement contributions require actual earned income from the business. That said, if you had any net profit — even a small one — you can contribute a proportionate amount. In a truly unprofitable year, your only retirement savings option is an IRA funded by any other earned income you may have from other sources.
Is an HSA really a retirement account?
It is not marketed as one. But for people who use it strategically, it functions like one — and with a triple tax advantage that no other account type in the tax code can match. Contributions are deductible, growth is tax-free, and qualified medical withdrawals are tax-free at any age. After 65, non-medical withdrawals are taxed at ordinary income rates, making it functionally equivalent to a traditional IRA for everything outside of healthcare costs. For women who tend to have higher healthcare needs in retirement, it is one of the most valuable tools available.
