Should You Contribute to Your Second Pillar in 2025?

Second pillar contribution

So, how does a voluntary contribution to the second pillar work?

Usually, you pay each month some amount of your salary to the second pillar. And this is matched by your company. You do not have a say in this. So, there is no way to optimize that.

However, you can contribute some amount to cover the holes in your second pillar. If you had a low salary when you started, you will surely have holes in your contributions. When you contribute, you can deduct it from your taxes, just like the third pillar. The second and third pillars are among the best tax deductions.

How much of a reduction in taxes this will realize is challenging to calculate correctly. It depends on your marginal tax rate. The amount will depend on your income, your wealth, and where you pay your taxes. In most cases, this will be between 30% and 40%. That means that the immediate rate of return of this contribution will be 30% to 40%. We can view voluntary contributions as a form of investment.

Now, the invested money will be blocked until you can take it. In the second pillar article, we have seen only four cases when you can take this money out:

• building a house
• starting a company
• retiring
• leaving Switzerland definitely

When withdrawing the money, you will pay a withdrawal tax. This tax depends heavily on each canton. The withdrawal tax is significantly lower than the taxes you can save with the contributions. You can save on the withdrawal taxes with staggered withdrawals.

Voluntary contributions are always blocked for three years (only the amount of the voluntary contribution is locked, not the entire second pillar).

As long as it is inside the second pillar, your money will get some interest rate. Unfortunately, the interest rate is currently low now. You can expect about a 1% interest rate in most pension funds in Switzerland. Nevertheless, it is a safe interest rate for now. It cannot go down. So, you can consider the second pillar as a place to allocate your bond.

However, if you are lucky, you will get a better pension fund. Some pension funds have average of up to 5% per year, but they are quite rare.

There is a second tax advantage to the second pillar. You do not have to pay taxes on the second pillar assets. So, if you have a large net worth, you will not have to pay wealth tax on your second pillar assets.

But this is a smaller advantage than the first one. It will still reduce your taxes a little further, but where the first tax advantage can be up to 40%, the second advantage is about 1% in the best case. Nevertheless, it is still important to know that you do not pay any wealth tax on your second pillar.

Scenarios

The obvious alternative is to invest in stocks. We can check how the same sum behaves if invested in stocks or contributed to the second pillar. First, we run some scenarios to see how that works. We will simulate a one-time investment of 10’000 CHF.

We start with a return per year of 3% for the stocks. This is a very conservative estimate. For the second pillar, we will consider 25%, 30%, 35%, and 40% marginal rates. The current interest rate on most second pillars is 1%. So we will take that as the reference.

The tax savings of the second pillar will be reinvested in stocks directly. So, if you have a marginal tax rate of 30%, 10’000 CHF invested in the second pillar will also result in 3000 CHF in stocks.

Finally, we will consider a 4% withdrawal tax on the entire amount. In practice, this would only apply to the second pillar, not to the savings you have invested. But in practice, the tax is often higher than 4%, so applying 4% to the total is a reasonable assumption.

Here are the results for twenty years.

As you can see, it takes about 15 years for the stocks to catch with even the lowest marginal rate. And it would take more than 20 years for the stocks to catch up with the high marginal tax rates.

In that case, a 3% return per year on the stock market is slow to catch up with a substantial interest rate as a tax deduction. So, if you expect 3% from stocks, you should probably favor your second pillar.

But generally, stocks are returning more than 3% per year. So, we will see what happens with a 5% return per year. This is what I expect on average from the stock market.

This time, it takes less than ten years for the stocks to increase as much as the second pillar, with the lowest marginal tax rate. But it almost takes 15 years to catch up with the highest marginal tax rates.

This exponential growth is the power of compounding. Even 5% per year can return a lot in the long term. 5% per year is what I expect from the stock market.

Obviously, in practice, you will not get 5% per year. You may get 10% one year and -20% the next year. But this is how the stock market works, and I am prepared for this. You can only expect average returns over the long term.

Now, some people are counting on about 7% of yearly returns. So, here is how that will go:

With 7% of stock returns per year, the return on the second pillar contributions is dwarfed. Even the highest marginal tax rates would be beaten after less than ten years. Compounding gets stronger and stronger as the returns increase.

So, we can draw a few conclusions from these results:

1. The second pillar is interesting if you have a high income.
2. The second pillar is interesting if you reinvest the tax savings in stocks
3. If you expect very high returns from stocks, you should avoid the second pillar
4. Over ten years, the second pillar is interesting
5. Over more than 20 years, the second pillar is rarely interesting

However, there are other considerations. First, it will depend on the term of your investment. If you are investing long-term, it is probably better to stick with stocks. But if you are to get access to your second pillar soon, it may be a solid investment. It could be a good investment if you retire soon, build a house, or start a company in the medium term.

But do not forget that voluntary contributions are blocked for three years. So, if you intend to buy a house in the next three years, you should not invest in the second pillar (unless you already have enough in the second pillar without the voluntary contribution). If you plan to buy a house without the second pillar, you can continue your contributions if you have enough cash for the downpayment.

Another thing you need to consider is whether you have a great second pillar account or not. If you have a good second pillar account invested in stocks, it will become more interesting to invest in it! But most people in Switzerland will not have access to a good second pillar.

The other consideration is whether you need bonds in your net worth.

Your bond allocation

Due to its safe nature and the guaranteed interest rate, I consider my second pillar bonds. I integrate my second pillar into my net worth as bonds.

So, another reason to buy into the second pillar depends on your allocation. If your bond allocation is too low for your current allocation, you can voluntarily contribute to increasing it. Given that it also has a nice tax advantage when you purchase, it is probably better than bonds.

When Swiss bonds are negative, the second pillar is also much more interest than Swiss bonds. If I need to increase my bond allocation, I will invest more in my second pillar instead of bonds.

At the start of 2021, we had 5.2% allocated bonds in our net worth. Since we aim for 10% bonds. So, it shows that we should contribute a little to our second pillar. Unfortunately, it is not a good time for us, as we will see in the next section.

Proper Timing

There are some cases where it becomes very interesting to make such contributions.

• When you know that you will retire or buy a house in the medium term (but further than three years). Since they are short-term investments, it is good to use them as such.
• When you know that you will leave your company and switch to vested benefits account. This could be the case when you are retiring early or leaving Switzerland. These accounts are often much better than second-pillar funds. So it could be interesting to max out your contributions to have them invested properly.

On the other hand, there is one case where you should not contribute to your second pillar: when you do not get any tax advantage. When you withdraw money early from the second pillar (for a house or business), you will not get any tax advantage until you have paid back the withdrawn money. So, as soon as you withdraw money from the second pillar, it becomes pretty much useless to put more money into it.

This is the case for us. We just withdrew money from our second pillar and cannot get any tax advantage until we contribute at least 50’000 CHF. So, without the tax advantages, it does not make sense for us to invest in the second pillar.

These examples show that timing is important for second pillar contributions.

Our second pillar strategy

We have decided to contribute to our second pillar each year. So far, we intend to contribute 10’000 to 20’000 CHF each year.

We have a few elements to back up our decision.

1. I plan to retire early. If my plan works, my money will only sit in a second pillar for at most 15 years. Then, it will go into a vested benefits account where it can be aggressively invested.
2. We have a high income in a high-tax canton, meaning a high marginal tax rate (at least 40%).
3. We currently have a decent second pillar The conditions are good, and the historical average return has been about 3% per year, which is above the average of second pillars.

If these conditions were not met, we would probably not contribute. But together, these conditions make the second pillar a good investment for us.

Use our calculator

If you do not want to do the math yourself for your exact situation, we have something that will help. This calculator will let you enter all the data about your situation:

• How many years until retirement
• Your taxes
• How much returns you expect from your second pillar
• How much returns you expect from your investments
• How much withdrawal tax you will pay on your second pillar at retirement

We hope this helps you find out for yourself whether a contribution to your second pillar makes sense for your situation or not.

Conclusion

From an investment standpoint, contributions to the second pillar can be a good medium-term investment. However, you should only do them if you have a high income.

Moreover, if you expect very high returns from your stocks, the second pillar becomes less interesting. And you should try to reinvest your tax savings in stocks. Even though they have a substantial initial return on investment, they have very low returns per year after that.

Moreover, the money in a second pillar is an excellent alternative to bonds. They have a guaranteed (at least for now) interest and offer an excellent tax reduction. These tax reductions would be quite interesting as one is nearing retirement. But remember that you can only contribute to your second pillar if you have a salary or have your own company.

But it is not necessarily the best investment at all times. Like every other investment, it will depend on your context and your situation. You should consider every element before you decide on any investment. And never make any rash decisions!

Finally, keep in mind that if you are withdrawing your second pillar from another country, the withdrawal taxes may be entirely different, so you will have to adapt the calculations if that is going to be the case for you.
