Key Points at a Glance
- The "large 3a": If you do not have a pension plan, you can contribute up to 20 % of your net income, capped at 36,288 CHF in 2026, compared to 7,258 CHF for an employee enrolled in a plan.
- Legal status: A sole proprietorship gives access to the large 3a; a LLC or a corporation makes you an employee of your company, thus subject to the LPP and limited to the small 3a.
- Coverage gap: Without a 2nd pillar, you have no disability or death protection beyond the OASI. This is what pillar 3a in insurance makes it possible to cover.
- 3a or 3b: In Geneva and Fribourg, a self-employed person can also deduct a 3b (life insurance) and keep funds accessible, instead of locking everything into the 3a.
- Why Pillar 3a Is Vital When You're Self-Employed Retroactive buy-ins in pillar 3a make it possible to close contribution gaps starting from 2025.
Why the 3rd pillar is vital when you are self-employed
Automatically, self-employed workers are only insured by the 1st pillar. Specifically, this means a total absence of occupational pension plan (BVG/LPP) : no pension fund for retirement, but above all no coverage in the event of loss of earnings or death beyond the minimum benefits of the AHV/IV.
Yet these benefits barely cover the bare minimum (maximum: CHF 2,520 per month in pension), which is very far from the actual standard of living of most entrepreneurs.
Are you truly «independent» in the eyes of the 3rd pillar?
Sole Proprietorship: The Large 3a
If you operate as a sole proprietorship (or a partnership) recognized as self-employed activity by your AVS/OASI compensation fund, the tax authorities treat you as fully self-employed. Without a pension fund, you're entitled to the "large 3a": up to 20% of your net income, capped at CHF 36,288 in 2026.
Founder of an LLC (Sàrl) or Corporation (SA): The Small 3a
If you've set up an LLC or corporation, the situation is different: legally, you're an employee of your own company. You're therefore required to be affiliated with the LPP (starting at CHF 22,680/year) and limited to the "small 3a" of CHF 7,258, just like any other employee.
How Much Can a Self-Employed Person Contribute in 2026?
- Without a pension fund (large Pillar 3a): 20 % of net operating income, up to a maximum of 36,288 CHF in 2026.
- With pension fund (small Pillar 3a): 7,258 CHF in 2026, like the employees.
How Much Does a Self-Employed Person Actually Save? A Worked Example
Let's take a self-employed person without a pension fund, single and childless, with a net income of 100,000 CHF. They pay the maximum allowed into their Pillar 3a, or 20 % of their income = CHF 20,000.
In Geneva and Fribourg, they also take out a Pillar 3b life insurance policy up to the cantonal deduction ceiling. Here's their annual tax savings, by canton of residence:
| Canton | Annual tax savings |
|---|---|
| Geneva (3a + 3b) | 6,901 CHF |
| Neuchâtel (3a) | 6,643 CHF |
| Vaud (3a) | 6,510 CHF |
| Valais (3a) | CHF 6,396 |
| Fribourg (3a + 3b) | 6,301 CHF |

2nd or 3rd Pillar: What Should the Self-Employed Choose?
The large 3a isn't the only option. A self-employed person whose net income exceeds CHF 100,000 has good reason to compare the large 3a against voluntary affiliation with a pension fund. Affiliating with the 2nd pillar as a self-employed person lets you deduct your contributions in full and, above all, make substantial buy-ins — a very powerful tax lever — but this affiliation brings your Pillar 3a back down to the small ceiling of CHF 7,258.
The trade-off is therefore between the simplicity and flexibility of Pillar 3a on the one hand, and the buyback capacity of the 2nd pillar on the other. For high and stable incomes, combining the two is often the most effective solution.
Pillar 3a or 3b: Which One Should a Self-Employed Person Choose?
Pillar 3a is the obvious tax reflex, but locking up all one's cash is risky for a self-employed person. While it is possible to withdraw your 3a to start a business, this reason only works once. After that, the capital remains inaccessible until retirement.
This is where the 3b becomes a strategic option, thanks to its full availability when cash is needed. In addition, in Geneva and Fribourg, the 3b offers specific tax deductions:
- Geneva: Deduction up to 2,345 CHF (single) or 3,518 CHF (couple), +959 CHF per child. These limits double if you do not contribute to the 2nd or 3rd pillar A.
- Fribourg: Life insurance premiums linked to 3b are deductible up to 750 CHF for a single person and 1,500 CHF for a couple.
Which Strategy Should You Adopt?
In these two cantons, the logic is reversed: it’s better to maximize the 3b before filling up the 3a. This approach allows you to claim an additional tax deduction while keeping 100 % in capital available for your self-employment cash flow, rather than tying up all your funds until retirement.
- Only downside: Unlike a 3a account, which is completely tax-exempt, the surrender value of a 3b account is included in your taxable assets.
Banking or Insurance: Which Option Should You Choose?
For a self-employed person, the choice of vehicle directly determines your level of protection. Without a 2nd pillar, a bank account or a retirement savings app offers total flexibility but covers no risk whatsoever.
If a disability occurs before sufficient funds have been accumulated, AVS/AI will cover only the bare minimum.
An insurance-based 3rd pillar, by contrast, includes essential guarantees to make up for the lack of occupational pension coverage:
- Premium Waiver: The insurer pays your premiums for you in the event of loss of earnings.
- Disability pension: a regular income to maintain your standard of living.
- Death or disability lump sum: an amount paid to protect your loved ones or yourself.
The downside of insurance lies in its contractual obligation: premiums must be paid regularly, which can strain fluctuating cash flow.
- The recommended strategy: Set an insurance premium that fits your budget to secure coverage for essential risks, then use a bank account or additional payments to your insurance policy to freely contribute the remaining amount up to your tax limit in good years. This way, you achieve the perfect balance between security and financial flexibility.
Withdrawing from Pillar 3a: Rules and Conditions
Pillar 3a capital can be withdrawn early in specific situations: purchasing your primary residence, permanently leaving Switzerland, being granted a full AI disability pension, or approaching retirement (starting 5 years before the reference age).
For the specific case of transitioning to self-employment, the following rules apply:
- Deadline: The application must be submitted within one year of the start of the activity.
- Status: This right applies only to sole proprietorships and partnerships (it does not apply to the formation of corporations or limited liability companies).
- Format: The withdrawal must be in full for the account in question; partial withdrawals are not permitted.
- Family: The written consent of the spouse or registered partner is required.
Upon withdrawal, this capital is taxed separately from your other income at a reduced rate that varies by canton. Having multiple 3a accounts allows you to spread out withdrawals over several years to mitigate the progressive nature of this tax.
Retroactive Pillar 3a Buy-Ins: Filling Your Gaps Starting in 2026
Since January 1, 2026, it's been possible to buy back your missed Pillar 3a contribution years to optimize your taxes — a major new option for smoothing out the income fluctuations that come with self-employment. This mechanism follows strict rules:
- History: Only gaps created on or after 2025 can be made up. Previous years are permanently lost.
- Priority: You must reach the maximum contribution limit for the current year (up to 36,288 CHF in 2026) before you can make a catch-up contribution.
- Redemption cap: The maximum amount that can be made up for each year of non-contribution is equal to the "minimum contribution" (7,258 CHF), not your self-employed contribution limit.
- Frequency: You have 10 years to fill a gap, with a maximum of one catch-up contribution every two years.
- Eligibility: You must provide proof of income subject to AVS for both the year of the gap and the year of the buyback, and you must not have received any retirement benefits under the 3a plan.
Example Buy-In for a Self-Employed Person
A self-employed person with no pension fund earns a net income of CHF 100,000 in 2025 (but contributes nothing that year), then CHF 120,000 in 2026. In 2026, they can both contribute for the current year and make up for 2025:
| Step | Rule | Amount |
|---|---|---|
| 1. Regular Membership Dues for 2026 | 20 % of 120,000 CHF | CHF 24,000 |
| 2. Buyback of the 2025 gap | Capped at the small contribution | 7,258 CHF |
| Total deductible in 2026 | Contribution + buyback | 31,258 CHF |
Self-Employed Cross-Border Workers: What Retirement Strategy?
- Pillar 3a: It is deductible only through the TOU. Without a 2nd pillar, your deduction limit increases to 36,288 CHF.
- Pillar 3b: This is the solution for non-quasi-residents. It offers total liquidity, allows for real estate pledging in France, and entitles the holder to a partial cantonal deduction in Geneva (2,345 CHF) and Fribourg (750 CHF).
The reasoning continues with the 2nd optional pillar, the ordinary contributions of which are deductible from Swiss income without the quasi-residency condition, while voluntary buy-ins require the TOU. The optimal setup therefore depends precisely on your place of residence and your income structure.
Frequently asked questions about the independent 3rd pillar
What is the 3rd pillar cap for a self-employed person in 2026?
A self-employed person without a pension fund may contribute up to 20 % of their net income, up to a limit of 36,288 CHF in 2026. If they are enrolled in a pension plan (as is the case for executives of limited liability companies [Sàrl] or corporations [SA]), the limit drops to 7,258 CHF, as it is for an employee.
Can a self-employed person deduct their 3rd pillar from their taxes?
Bank or insurance company: Which one should you choose for a 3a plan as a self-employed person?
Insurance covers the risks (premium waiver, disability pension, death benefit) left uncovered by the absence of a 2nd pillar; the bank only offers savings, with more flexibility and generally lower fees. The most solid solution is often insurance complemented by a bank account.
