Pillar 3a is a powerful tool in the Swiss pension system. By making contributions to a 3a account, you can reduce your taxable income and save on your taxes, while building up savings for retirement. Here are the key points to remember:
- Immediate tax benefits : Contributions are deductible from taxable income (within the limits of the annual limits).
- 2025 ceilings : CHF 7'258 for employees and up to CHF 36'288 for the self-employed without a pension fund.
- Marginal tax rate : The higher your rate, the more you save. For example, a rate of 32% on a contribution of CHF 7,258 generates savings of CHF 2,323.
- Key Factors : Your canton, your income and your family situation influence your tax savings.
To maximize your benefits, Pay early in the year, spread your contributions across several accounts and use online simulators for accurate calculations. Pillar 3a is a simple solution to optimize your taxes and ensure a comfortable retirement.

How to calculate your tax savings
Now that we've seen how pillar 3a can reduce your taxes, let's see how to calculate your tax savings step by step. This is done in three steps: identify your contribution limit, determine your tax rate, and then multiply these two values.
Determine your maximum contribution limit
The contribution limit depends on your professional status and your pension fund membership.
- For employees and self-employed persons affiliated to a pension fund, the contribution limit for 2025 is set at CHF 7'258 [1].
- For self-employed persons not affiliated to a pension fund, you can pay up to 20% of your net income, with a maximum of CHF 36'288 in 2025 [1].
Let's take two examples. A self-employed person with a net income of CHF 80,000 will be able to contribute 20%, or CHF 16,000. If his net income reaches CHF 200,000, he will be capped at CHF 36,288.
From 2026, it will be possible to make retroactive payments for the previous ten years (starting in 2025) [1]. This option is reserved for those who have not reached the maximum contribution limit in past years.
Determine your tax rate
Your marginal tax rate combines federal, cantonal, and municipal levels. This is the rate that applies to the pillar 3a deduction.
- The federal rate is uniform throughout Switzerland and follows a progressive scale of up to 11.5% for the highest incomes.
- Cantonal and communal rates vary depending on where you live. For example, a single person with an annual income of CHF 100,000 may have a total marginal rate of around 22% in some municipalities in Zug, compared to more than 40% in some municipalities in Geneva or the canton of Vaud.
To find out your exact rate, consult your last tax return or use the tax calculators available on the official websites of your canton.
Calculate your tax reduction
To find out your tax savings, simply multiply the amount of your contribution by your marginal tax rate:
Tax savings = Pillar 3a contribution × Marginal tax rate
Let's take two concrete examples:
-
Marie, an employee in Lausanne, earns CHF 85,000 per year and has a marginal rate of 32%. If she pays the maximum of CHF 7,258, her tax savings will be:
CHF 7'258 × 32% = CHF 2'323 -
Thomas, a self-employed person not affiliated to a pension fund with a net income of CHF 120,000 and a marginal rate of 35%, will contribute CHF 24,000. Its fiscal savings will then be:
CHF 24,000 × 35% = CHF 8'400
In some cantons, pillar 3a contributions can also reduce wealth tax, which is in addition to the income benefit.
To simplify these calculations, the platform Best Third Pillar offers free simulation tools. These tools take into account your personal situation and your canton of residence, allowing you to obtain an accurate estimate in a few clicks. This helps you optimize your contributions and maximize your tax benefits.
Factors that influence your tax savings
Once the basic calculation has been made, several personal elements modulate the final amount of your tax savings. Here are the main aspects to consider:
Cantonal and communal tax rates
Where you live plays a key role in calculating your tax savings. In Switzerland, tax rates vary considerably from canton to canton or municipality. For example, a maximum contribution to pillar 3a can generate very different tax savings depending on the marginal rate applied in your region. Some municipalities or cantons offer lower rates, while others apply higher rates. These rates are also subject to regular adjustments, which can affect your savings from year to year. In addition to local rates, your income level is a determining factor in this calculation.
Income level and tax bracket
Your annual income determines which tax bracket you are in. The higher your income, the more you are taxed, which means that the deduction offered by pillar 3a becomes all the more advantageous. An identical contribution can therefore generate much greater tax savings for a person with a high income. In addition, the pillar 3a deduction can sometimes cause you to fall into a lower tax bracket, thus reducing your tax burden even further. Self-employed individuals, on the other hand, can contribute higher amounts, allowing them to maximize their tax savings based on their income. Finally, it is important to consider these aspects in relation to your family situation.
Marital status and family status
Your family situation also influences the fiscal impact of your contributions. Married couples and families often benefit from advantageous arrangements, such as marital splitting or child deductions, which lower their marginal tax rate. This makes the pillar 3a deduction even more effective. On the other hand, a single person, without these benefits, could see a greater fiscal impact from their Pillar 3a contribution. For couples, it may be interesting for each spouse to open a separate pillar 3a account, especially if their incomes are comparable. Finally, specific situations, such as maintenance obligations for divorcees, require a personalized approach to optimize tax savings.

Digital advances make calculating the tax savings associated with pillar 3a much more accessible. These online tools take into account the specificities of your personal situation to offer you accurate and adapted estimates. Let's see how these simulators work and how they can simplify your procedures.
Tax calculation tools available
Online tax simulators ask for key information like your domicile, your family situation, your profession and your taxable income. This data makes it possible to apply local tax rates and to generate a reliable estimate. For example, the platform Best Third Pillar offers a free simulator that guides you step by step.
These tools take into account cantonal and municipal tax rates that are updated regularly, in order to provide results adapted to your place of residence.

Then, they are constantly updated to reflect current tax rates, ensuring reliable results. These tools also allow you to test different scenarios, helping you determine the ideal contribution to maximize your savings.

How to maximize your tax benefits
Once you've calculated your savings, it's time to adjust your strategy to get the most out of them. Pillar 3a is a powerful tool for optimizing your tax benefits, and simple adjustments to the timing and distribution of your payments can make a big difference in the long run.
Make payments at the beginning of the year
The timing of your contributions to pillar 3a can have a direct impact on the performance of your investments. By paying the maximum amount at the start of the year, you benefit from a longer capitalization period, which can increase your returns. In addition, it immediately guarantees you the tax deduction for the current year. By planning regular payments as early as January, you are putting every chance on your side to maximize the growth of your retirement savings.
Distribute contributions across multiple accounts
Dividing your contributions across several 3a accounts is an effective strategy to better manage the tax impact during withdrawals. For example, by spreading your savings across two or three accounts, you can spread withdrawals over the years, reducing the taxable amount each year. This can be particularly useful in situations like early retirement or the purchase of real estate. In addition, this approach allows you to diversify your investments according to your financial goals, thus offering more flexible management adapted to your needs.
Get professional financial advice
Pillar 3a tax optimization requires personalized thinking, taking into account your income, family situation and long-term goals. A financial advisor can help you identify opportunities that automatic tools might miss.
Best Third Pillar offers tailor-made advice to refine your strategy. The experts analyze your overall situation, guide you to the most suitable products and take into account legislative and fiscal developments. Their support is particularly useful during major changes such as a salary increase, a marriage, the birth of a child or a move to another canton. In addition, annual follow-ups allow you to adjust your strategy according to the evolution of your personal situation and the market, ensuring that your pillar 3a stays in line with your goals while maximizing your tax benefits year after year.
Conclusion
The benefits of pillar 3a
Pillar 3a combines two major benefits: an immediate tax reduction and a long-term retirement savings. On the one hand, it allows you to deduct your contributions from your taxable income, within the limit of the annual limit set for employees. This can translate into several thousand francs in tax savings, depending on your tax rate. On the other hand, funds invested in pillar 3a grow tax-free for years, creating a snowball effect through capitalization. This mechanism can transform your regular payments into substantial retirement capital.
In short, pillar 3a is a powerful financial solution. The tax savings made each year can be reinvested to maximize your long-term gains, strengthening your future financial security.

Be sure to properly estimate your annual income in order to take full advantage of tax benefits, while respecting the legal limits. To optimize your strategy, it may be a good idea to consult a financial advisor or to use calculation tools adapted to your needs.

In just a few moments, these tools generate a clear estimate of your potential tax savings. This allows you to better plan your savings for retirement while optimizing the management of your finances.

How does your family situation affect your tax savings with pillar 3a?
Your family situation plays a central role in calculating the tax savings associated with pillar 3a. In Switzerland, the marginal tax rate varies depending on several factors such as your marital status, the number of dependent children or whether you are taxed individually or jointly.
For example, a married person with children will often have a different marginal tax rate than a single person. This difference can have a direct impact on the amount of tax savings you can achieve through your annual Pillar 3a contributions. To take full advantage of these tax advantages, it is important to carefully analyze your personal situation and to use specific simulation tools.
