What tax savings do we achieve with a 3rd pillar A?
Eligibility conditions and contribution limits
Before exploring ways to optimize your contributions through simulations, it is essential to fully understand who can contribute and what limits apply.
Who can contribute to the 3rd pillar?
To access pillar 3a, three main conditions must be met:
- Tax residence in Switzerland : This condition concerns both Swiss citizens and foreigners living in the country. However, cross-border workers working in Switzerland but living abroad generally do not have access to pillar 3a.
- Income subject to AVS : Employees, self-employed persons, as well as certain specific profiles, such as members of boards of directors receiving attendance fees, can contribute. On the other hand, people who are not working for profit, such as students or pensioners, are not eligible.
- Age limit : You can contribute up to age 65. If you continue to work after this age, it is possible to extend your contributions for another five years.
Once these criteria have been met, it is important to know the specific contribution limits for 2025, which vary according to your professional status.
2025 annual contribution limits
The deduction limits applicable in 2025 depend on your professional situation:
- For the employees affiliated to a pension fund (2nd pillar), the maximum deduction is CHF 7'258. This ceiling concerns the majority of employees in the private and public sectors who already benefit from occupational benefits.
- Les self-employed without a 2nd pillar benefit from a larger margin, with an authorized deduction of up to 20% of their annual net income, within the limit of CHF 36'288. This distinction is explained by the absence of compulsory occupational benefits for this category.
Respecting these ceilings is crucial. Any amount paid in excess will not be tax deductible, which negates the expected benefit.
This rule applies to Total contributions, even if you have multiple 3a accounts. For example, if you deposit CHF 4,000 in one account and CHF 4,000 in another, you exceed the ceiling of CHF 7,258 for an employee. The excess of CHF 742 cannot be deducted.
To avoid this type of overrun, it is a good idea to schedule a monthly standing order. For example, an automatic payment of CHF 605 per month makes it possible to respect the annual ceiling for employees.
Self-employed persons should be particularly vigilant, as their ceiling depends on their annual net income. One regular monitoring of their financial situation is essential to adjust their contributions and avoid exceeding the authorized 20%. In this context, simulations can be very useful to optimize your payments according to the evolution of your income.
How to use simulation tools
Now that you're familiar with the eligibility limits and requirements, let's see how to get the most out of simulation tools. These tools are designed to help you estimate your tax savings and determine the optimal amount to contribute based on your personal circumstances.
Use online simulation tools
To get reliable estimates, it is essential to provide detailed information about your situation. Here are the main data to prepare:
- Your age, canton of residence and family situation (for example, single, married, number of children).
- Your professional status : are you employed or self-employed? If you are an employee, specify whether you are affiliated with a 2nd pillar pension fund.
- Your annual taxable income, which plays a key role in calculating your tax savings.
- The annual amount you plan to contribute and your investment strategy (rather conservative or growth-oriented).
- If you already have 3a assets that you want to transfer, don't forget to indicate this.
Once this information is entered, the tool will provide you with clear and detailed projections that we explore further.
Interpreting your simulation results
After entering your data, the tool generates results that allow you to better understand your tax situation and retirement prospects. Here are the main points to be analyzed:
- Your annual tax savings, which vary according to your canton of residence and your tax situation. For example, self-employed persons without a 2nd pillar can benefit from higher contribution ceilings, which can lead to substantial savings. For their part, married couples can benefit from specific tax advantages depending on their canton.
- A projection of your pension capital, based on the estimated returns according to the investment strategy chosen.
These results provide you with a solid basis for adjusting your strategy and maximizing your fiscal and financial benefits.
Tips for more efficient simulations
To take full advantage of simulation tools, adopt a thoughtful and proactive approach:
- Experiment with different contribution amounts to find a balance between tax savings and the available budget. There is no point in aiming for the maximum amount if it puts your monthly finances at risk.
- Update your simulations after any significant change: an increase in income, a move to a new canton, or a change in your family situation can change your potential tax savings.
- Explore the investment options available. A more dynamic approach may offer higher returns in the long run, but it also comes with greater risks.
With a methodical approach and up-to-date data, you can optimize your contributions and effectively prepare for your financial future.
