The 3rd Swiss pillar is an effective solution to prepare for your retirement while reducing your taxes. However, many make mistakes that can have a major impact on their long-term savings. Here are the top 5 mistakes to avoid:
- Starting too late : Each year of delay reduces the effect of compound interest, which can cost you thousands of francs in retirement.
- Choosing an unsuitable plan : Not understanding the differences between pillar 3a and 3b may limit your tax benefits or flexibility.
- Neglecting tax savings : Poor contribution planning or oversights in the tax return can reduce your profits.
- Making bad investments : Choices that are too conservative or poorly diversified can erode your capital in the face of inflation.
- Withdrawing money too soon : Early withdrawals slow the growth of your savings and lead to high taxes.
Take action now can make a big difference to your financial future. In this article, you'll find practical tips to avoid these mistakes and maximize the benefits of your 3rd pillar.

Mistake 1: Starting your 3rd pillar too late
Postponing the start of your 3rd pillar contributions is one of the most expensive pension mistakes. Why? Because of The effect of compound interest, which plays a critical role in growing your savings. The sooner you start, the more time your capital has to grow. Each year that you are late can therefore cost you a lot of money in retirement.
Many young workers think they still have plenty of time ahead of them or prefer to wait until they have a higher income before starting to contribute. But by doing so, they are missing out on one of the biggest advantages: time, which is essential for building solid assets.
How much does this delay cost?
Let's take a concrete example to illustrate the impact of time on your contributions.
Let's imagine that two people, Sarah and Marc, each contribute CHF 6,883.- per year, which is the maximum amount authorized for pillar 3a in 2025, with an average annual return of 3%.
- sarah starts contributing at the age of 25 and continues until age 65. In 40 years, she will have paid CHF 275,320.-. Thanks to compound interest, its capital will reach approximately CHF 520,000.-.
- marc, for him, waits until he is 35 years old to start. He contributes for 30 years, 10 years less than Sarah. He pays a total of CHF 206'490.- and accumulates approximately CHF 340,000.-.
In the end, although Marc contributed almost CHF 70,000 less, he ended up with CHF 111'170.- less that Sarah is retired. Why such a difference? Because Sarah's contributions have had 40 years to grow, compared to only 30 years for Marc's.
How to start contributing now
It is never too late to make good decisions. Here are some tips for starting your 3rd pillar right away, even if your budget is limited.
- Start with an amount adapted to your means. You don't need to contribute as much as you can from the start. Even CHF 100.- or CHF 200.- per month is enough to get started. The key is to get in the habit and let time and compound interest do the rest.
- Automate your payouts. Set up an automatic transfer to your 3rd pillar account just after receiving your salary. This ensures regular savings without effort and turns this practice into a reflex.
- Increase your contributions gradually. For each pay increase, adjust your payments. This allows you to strengthen your savings without changing your standard of living.
- Use online simulators. Banks and other financial institutions offer tools to estimate your immediate tax savings through contributions. Seeing these concrete numbers can be a great source of motivation.
In short, every year counts. Even a small effort today can make a big difference in your future.
Mistake 2: Choosing the wrong type of 3rd pillar
After understanding the importance of starting early, choosing the type of pillar that's right for you is just as essential. Many find themselves opting for pillar 3a or 3b without taking the time to analyze their personal situation. This approach can lead to costly choices in the long run. Too often, a “standard” solution is adopted without considering individual goals, investment horizon, or the need for flexibility. However, each financial situation deserves a tailor-made analysis.
The main problem lies in a poor understanding of the fundamental differences between these two options and their long-term impacts. For example, some people prefer pillar 3a for its tax benefits, while neglecting its withdrawal restrictions. Conversely, pillar 3b offers considerable flexibility to finance various projects, but with lower tax savings.
Pillar 3a vs 3b: The key differences
Here is an overview of the major differences between these two options:
Pillar 3a is ideal if you want to maximize your tax savings while making a long-term commitment to retirement. Its restrictions ensure that savings remain dedicated to this objective. On the other hand, pillar 3b is distinguished by its flexibility, making it possible to finance projects such as the purchase of real estate or other investments, while offering certain tax breaks.
A word of caution for American expats: Pillar 3 solutions are often discouraged due to strict U.S. tax rules and complex reporting requirements.
With these differences in mind, here's how to align your choice with your financial needs.
How to choose the solution that's right for you
To make the right choice, carefully consider your financial situation and priorities:
- Clarify your financial goals. Above all, do you want to optimize your retirement or finance medium-term projects?
- Analyze your investment horizon. If you are more than 15 years away from retirement and buying a home is not in your immediate plans, pillar 3a can offer a good balance between tax benefits and returns. For short-term needs or greater flexibility, pillar 3b is often more appropriate.
- Assess your risk tolerance. Both pillars offer a variety of investment options. However, the constraints of pillar 3a often make it possible to adopt bolder strategies over the long term.
- Consider a mixed approach. A combination of the two can be a good idea. In Switzerland, almost two thirds of employees have a 3rd pillar account. You can maximize Pillar 3a contributions to take advantage of tax benefits, while supplementing with Pillar 3b to maintain flexibility.
To help you, free simulation tools, such as those available on Best Third Pillar, allow you to calculate your potential tax savings and to project your retirement capital according to different scenarios. These tools take into account your tax specificities and your personal goals.
Finally, do not hesitate to consult an independent expert. Personalized advice can make all the difference in assessing your risk profile and developing a strategy tailored to your needs.
Keep in mind that your choices may change over time, depending on your personal or professional changes.
Mistake 3: Missing tax savings opportunities
One of the most costly mistakes associated with the 3rd pillar is not taking full advantage of possible tax savings. Many think that contributing is enough to maximize the benefits, but a careless approach can cause you to lose hundreds of francs each year, or even more, depending on your tax bracket.
The main problem lies in poor contribution planning and a lack of knowledge of tax rules. Some make their payments irregularly, others forget the opportunities to catch up, and many are unaware of the fiscal impact of their choices. These mistakes can represent a significant shortfall in the long run. Let's take a closer look at the opportunities that are often overlooked and how to avoid them.
Tax deductions you could miss
Here are some common mistakes that can limit your savings:
- Partial contributions at the end of the year : Many wait until December to make their annual payment, often without verifying that they reach the authorized limit. For 2025, note that this ceiling varies according to your situation: it is lower for employees affiliated to a pension fund and higher for the self-employed without a LPP. A difference of a few dozen francs could be enough to reduce your tax deductions.
- Catch-up payments : If you did not contribute the maximum amount in previous years, it is sometimes possible to make up for this delay, depending on the conditions of your contract. This option can be particularly beneficial if your taxable income has increased.
- Irregular payments : Spreading your contributions over a short period of time can limit your tax benefits, especially if your income or employment situation fluctuates during the year.
- Wrong reporting of payments : Even if your contributions are optimal, forgetting to report them correctly on your tax return is a classic mistake that negates your savings efforts.
- Ignore cantonal specificities : Each canton applies its own tax rules, and the benefits of the 3rd pillar can vary considerably depending on where you live. Cross-border residents should pay particular attention to these differences.
Maximizing these deductions is essential to fully benefit from the tax advantages of the 3rd pillar and to prepare for a comfortable retirement.
How to optimize your tax savings
To get the most out of your 3rd pillar, here are some strategies to adopt:
- Plan your contributions at the start of the year. Determine the maximum amount that can be deducted according to your situation and set up automatic monthly transfers. If your income varies, adjust your contributions accordingly: a year of high earnings may justify making a maximum contribution to reduce your taxes.
- Use simulation tools. Free calculators, such as those offered by Best Third Pillar, help you estimate your tax savings taking into account your canton, professional status and income. These tools take into account local particularities to offer an accurate estimate.
- Keep track of your payments. Keep all the proof of contributions and check that the amounts are correctly reported on the tax certificates provided by your insurer or bank. These documents are essential for your tax return.
- Ask for advice for complex situations. If you are a cross-border worker, self-employed or if your tax situation is specific, an expert can help you optimize your contributions. Best Third Pillar advisors offer free consultations to analyze your situation and identify opportunities.
- Review your strategy every year. Your needs and circumstances change over time. An annual review allows you to adjust your approach and take advantage of potential new opportunities.
Each year of tax optimization contributes to significant savings in the long term. Rigorous management of your 3rd pillar fits perfectly into a global strategy for preparing for retirement.
Mistake 4: Wrong investment choices and insufficient diversification
Making poor investment choices or not diversifying your investments sufficiently can be very expensive in the long run. Many people let their money sleep in low-yielding savings accounts in order to protect their capital. However, this approach is gradually eroding purchasing power, especially in the face of inflation.
This error is often the result of an underestimation of risks and a fear of volatility, which leads to excessively conservative investments. But in the long term, this caution can be riskier than a balanced and well-diversified strategy. Here's why low returns can have a big impact on your savings.
Why low-yielding accounts make you lose money
Pillar 3 savings accounts offer annual returns of between 0.25% and 0.75%. However, with an average inflation in Switzerland of 1.5% to 2.0%, your purchasing power is decreasing year after year.
Let's take a concrete example. If you save CHF 7,056 each year (the maximum expected for 2025 with a pension fund) in an account with a return of 0.5%, you will accumulate around CHF 282,240 after 35 years. But taking into account inflation, this sum will only have a purchasing power equivalent to around CHF 141,120 today. In other words, you're losing half of your savings without even realizing it.
In addition, annual fees of 1.0% to 1.5% can result in an additional net loss of CHF 50,000 to CHF 75,000 over 35 years, reducing your return even further.
By only opting for conservative accounts, you are also missing out on the powerful effects of compound interest on financial markets. For example, a diversified portfolio with an average return of 4% to 5% could generate final capital two to three times that of a traditional savings account over the same period.
Building a balanced investment portfolio
To avoid these pitfalls, it is essential to adopt a balanced investment strategy that maximizes returns while limiting risks.
- Geographic and sectoral diversification : Divide your investments between different regions and sectors. For example, you could allocate 40% to Swiss stocks, 30% to international stocks, 20% to bonds, and 10% to alternative investments like real estate or commodities.
- Allowance according to age : A simple rule is to subtract your age from 100 to determine the share of stocks in your portfolio. So, at 30, you could have 70% stocks and 30% bonds. At age 50, this distribution would increase to 50% shares and 50% bonds, which makes it possible to progressively secure your capital as you approach retirement.
- Index funds (ETFs) : ETFs are a practical and inexpensive option for diversifying your investments. For example, an ETF based on the index SMI allows you to invest in the 20 largest Swiss companies with annual fees that are often less than 0.3%. Likewise, an ETF World gives you access to more than 1,600 global companies for similar fees.
- Annual rebalancing : Reviewing your portfolio once a year allows you to maintain your target allocation. This involves selling assets that have performed well and buying those that are temporarily undervalued, thus optimizing your long-term returns.
Finally, use tools or calculators to simulate different strategies based on your risk profile and goals. These tools take into account parameters such as inflation, fees, and taxation to give you a realistic projection of your retirement capital. If necessary, call on an advisor to develop a personalized strategy and optimize your investments, especially in the context of the 3rd pillar.

Mistake 5: Withdrawing your money too soon
Reaching your 3rd pillar early can be one of the most expensive retirement decisions. Often motivated by urgent financial needs or a lack of information, this choice can destroy years of savings efforts and compromise your long-term financial security.
The main problem? You're breaking the compound interest process. Each withdrawal slows the growth of your capital, and you lose not only the amount withdrawn, but also the gains that this amount would have generated over the long term.
The real cost of early withdrawals
Early withdrawal can also lead to high taxation, as 3rd pillar withdrawals are taxed separately from your usual income. If you spread your withdrawals over several years, you reduce this tax burden. Also, remember that retirement can last for decades: keeping your capital is essential to ensure a sustainable income.
Let's take an example. If you withdraw CHF 50,000 at the age of 50 from an account that generates 4% annual interest, you lose much more than this amount. In 20 years, this amount would have produced an additional CHF 108,000. In total, this withdrawal costs you CHF 158,000.- at the age of 70.
As with mistakes related to bad investments or choosing a plan, withdrawing your money too soon greatly reduces the cumulative growth of your savings. It is therefore crucial to opt for a gradual withdrawal strategy.
Preparing for a long-lasting retirement
To avoid these mistakes, develop a withdrawal strategy that protects your capital throughout your retirement:
- Split your withdrawals : Prefer partial withdrawals spread over several years rather than a single withdrawal. This limits your annual taxation and lets the rest of your capital continue to grow.
- Coordinate your income : Plan your 3rd pillar withdrawals taking into account theAVS, the 2nd pillar and your other investments to optimize taxation.
- Create an emergency fund : Keep a cash reserve in a traditional savings account to manage the unexpected without touching your 3rd pillar.
- Review your strategy regularly : Adjust your withdrawals according to your needs, the evolution of your assets and economic conditions to preserve your savings.
Finally, do not hesitate to consult a financial advisor who specializes in retirement planning. If you are a cross-border resident or a foreign resident, an expert can help you design a tailor-made strategy that maximizes the duration of your savings while reducing your taxes.

Pillar 3a is distinguished by its major tax advantages. Indeed, the contributions you make are deductible from your taxable income, which can significantly reduce your tax burden. Conversely, pillar 3b, while offering greater flexibility in managing and withdrawing funds, does not allow you to take advantage of these tax deductions.
To get the most out of pillar 3a, it is advisable to start contributing as soon as possible. This allows you to benefit from tax deductions every year while increasing your savings. Also, consider choosing investment strategies that are aligned with your financial goals and your personal situation, while respecting the tax rules in force in Switzerland. This approach can optimize the return on your contributions over the long term.
How do I choose the best investment options for my 3rd pillar to protect my savings from inflation?
To protect your savings from inflation thanks to the 3rd pillar, opt for investments with high potential for long-term growth, like diversified equity funds or portfolios that include securities. These types of investments can better compensate for the loss of purchasing power caused by inflation.
It is also essential to diversify your investments. This may include a combination of different asset classes, such as mixed funds or balanced portfolios, in order to limit risks. Consider key elements like your Investment horizon, your risk tolerance, as well as the tax advantages specific to Switzerland.
