Should You Contribute to Your Second Pillar in 2021?

In Switzerland, you can make a voluntary contribution to your second pillar. These contributions come with some tax advantages since you can deduct that from your income. Therefore, you have a return equal to your marginal tax rate. And this return is almost instant.

However, the money is then blocked into the second pillar. And the returns on that blocked money have been very low in recent years. Finally, you can only withdraw the money from your second pillar if you retire, buy a house, or start a company.

Many people ask whether they should contribute money to their second pillar or continue investing in stocks.

In this article, I am going to answer this question.

Second pillar contribution

So how does a voluntary contribution to the second pillar works?

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 yourself to cover the holes in your second pillar. If you had a low salary when you started, you are sure to have holes in your contributions. When you contribute, you can deduct it from your taxes, just like the third pillar.

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, or leaving Switzerland. In those cases, you will lose out a part of the second pillar as taxes. But this is not as much as your marginal tax rate. And voluntary contributions are always locked for three years.

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

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.


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 of all, let’s run some scenarios to see how that works.

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

Second pillar vs Stocks (3% per year)
Second pillar vs Stocks (3% per year)

As you can see, it takes 13 years for the stocks to catch with even the lowest marginal rate. And it takes about 17 years to catch with the largest marginal rate. In that case, a 3% return per year on the stock market is slow to catch up with a substantial interest as a tax deduction.

But generally, stocks are returning more than 3% per year. So let’s see what happens with a 5% return per year.

Second pillar vs Stocks (5% per year)
Second pillar vs Stocks (5% per year)

This time, it takes less than ten years for the stocks to go up as much as the second pillar. And they are ending up much higher. 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 return per year. So, let’s see how that will go:

Second Pillar vs Stocks (7% per year)
Second Pillar vs Stocks (7% per year)

With 7% of stock returns per year, the return on the second pillar contributions is dwarfed. Compounding gets stronger and stronger as the returns increase. After twenty years, your stocks will be worth more than twice your second pillar contribution.

Based on this uniquely, one should probably not invest in the second pillar.

However, there are other considerations. First of all, it will depend on the term of your investing. If you are investing in the 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 are going to retire soon or if you are going to build a house or start a company in the medium-term.

But, do not forget that voluntary contributions are locked for three years. So if you intend to buy a house in the next three years, you should not invest in it.

Another thing you need to take into account 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 the great majority of people in Switzerland will not have access to a good second pillar.

The other consideration is whether you need bonds in your net worth or not.

Your bond allocation

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

So another reason to buy into the second pillar is depending on your allocation. If your bond allocation is too low for your current allocation, you can make a voluntary contribution to increasing it. Given that it also has a nice tax advantage when you purchase, it is probably better than bonds. Especially, it is better than Swiss bonds that have a negative interest rate. If I need to buy bonds, I will contribute to my second pillar.

For instance, here is the allocation of my net worth at the start of 2021:

Our Net Worth Allocation as of March 2021
Our Net Worth Allocation as of March 2021

We currently have too few bonds in our portfolio. We aim for our bonds to be 10%, and it is currently 5.2%. 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, you will retire or buy a house in the medium-term (but further than three years). Since they are a short-term investment, it is good to use them as such.
  • When you know you are going to leave your company and switch to a 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 into it. 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.


It is clear from the different scenarios from an investment point of view that contributions to the second pillar are not as good as it seems. Even though they have a substantial initial return on investment, they have very little returns per year after that.

Nevertheless, 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 are something that would be quite interesting to do as one is nearing retirement. But keep in mind 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!

Since our marginal tax rate is getting higher and higher, I wish I could contribute a little to the second pillar. Unfortunately, we just withdrew 50’000 CHF from it. So, we would need to contribute 50’000 CHF back without tax advantages before we could get tax advantages. So, we will not contribute to our second pillar. The only reason for us to contribute would be if Mrs. The Poor Swiss gets a job, and then we could contribute to hers to save money on taxes.

What do you think about this? Are you contributing to your second pillar?

  1. Hi there,
    Maybe joining the debate a bit late, but do you consider that your tax saving investing in a 2nd pillar where reinvested. I.e you buy back 50K CHF of second pillar save 20K CHF of tax that you can re-invest. That’s a massive argument for second pillar.

    Good article and good comment section globally, thanks for that

  2. Hi, I was just wondering if in your simulation you took into account that the money invested in stocks is subjected to 1) Capital tax during the entire period and most importantly 2) withhold tax when converted back to cash. I guess if you consider this the figures would look less attractive for the stock investment option?

    1. Hi Investor,

      I did not take 1) into account because wealth tax is generally small and extremely different in each canton and for each investor. For instance, because of my house, my taxable wealth is zero. But that’s still an argument in favor of second pillar.
      I do not understand what you mean by 2) ? There is no withholding tax when converting stocks to cash. What do you mean?

  3. Hi,

    How is the tax-gap specified?

    Assume someone who starts working in Switzerland in 2021
    I assume initial tax-gap is zero?
    Or can there be a contribution for years prior to 2021 (out of Switzerland)?

  4. Thank you.
    They seem to think there is some problem with me not earning a threshold amount of CHF 22,000 a year (or so) which they call the threshold amount. It is for this reason they do not want to accept the money from the vested benefits account. I will persue the matter further. Your input was greatly appreciated.

    1. Hi Bruno,

      Unfortunately, they are correct. To contribute to the second pillar, you need a minimum yearly income of around 21K CHF. Below that, you will not be eligible to the second pillar.

  5. The 2nd pillar is highly underrated. Sure it’s boring and it doesn’t make headlines, I understand it. A lot of people have a 40%+ marginal tax rate, so the initial tax saving is huge. Even for those of us living in lower tax cantons we save around 30% from the taxman. Speaking for myself I never paid more than 6-7% in tax and I am proud of it. My 2nd pillar average return for the last years is around 3.5%. My fund(s) were only average, there were good years and bad years. Not great but ok considering the much lower risk. Even if your retirement is far away – lets say you are only 40 you can use the money to pay off your house or buy your home with cash. I know this is very unswiss, but you get rid of your debt. The only issue I have is that I am running out of the retiring plan gap and find myself chasing a new higher paid job in order to have the gap again. Not paying tax is kind of addictive.

    There are a lot of cons and pros but I think the 2nd pillar is a no brainer. 2nd pillar investments are not so efficiently managed, the whole financial industry takes advantage of it. But so do you. For me it’s show me the money and just future profits won’t do it.

    Should I say that I have a small investment made 15 years ago in some small markets and until now I haven’t got my initial investment back. The same can happen to any market.

    Probably the best way is to consider the 2nd pillar some kind of bond investment and also invest in the stock market taking into account that you can lose most of the money invested.

    1. Hi X41,

      I would think it highly depends on the second pillar you have. You may not realize it, but you already have a good second pillar. My second pillar returns 1% per year (and only on the mandatory part).
      If my second pillar had a 3% return, I would invest.

      So, I do not agree that this is a no-brainer. If you have a bad (average) second pillar, like me, you should not invest. If you have a good second pillar like you, it’s a good investment indeed.
      Also, it is only interesting when you have the tax advantages (like most people).

      But I completely agree that the second pillar should be considered as bonds.

  6. Thank you for the article. Very nice and informative. Would 3 year lock-in for voluntary contribution be applicable even if you decide to leave the country? Or in that case, it would be possible to withdraw earlier?

    1. Hi Vishal,

      That’s a good question. I am not sure honestly. I would think that it does not apply in that case, but I am not sure. I would contact your second pillar provider to ask them this question.

      1. In reply to the question above, the 3-year lock-in period still applies even when you leave the country. You have to wait until the expire of 3-year to be able to withdraw it.

          1. Dear Mr. The poor Swiss.
            I have recently got a new job but it is only working 9 hrs a week for 9 months of the year.
            I am over 61 and have been collecting unemployment benefit for over a year.

            The new employer has a pension fund. My question is:-

            a. Can I transfer the money from my Vested benefits account into the new employers pension fund.

            b. Can I make personal payments into the new pillar 2 fund.

            If I am unable to do a. or b. are there any other ways I could reduce my tax burden and save effectively for my upcoming retirement?

          2. Hi Bruno,

            a) You can transfer the money from your vested benefits account to the new pension fund. And in theory, you are obligated to do so, but nobody will check and as such, this is kind of a grey area. However, this will make nothing for your tax burden.
            b) Normally yes. You have to contact the pension fund and ask them how much you can contribute. And then you can do some contributions. Keep in mind that these contributions will be locked for 3 years.

        1. i can confirm this. 3yr lock-up applies for cash withdrawal too. I am currently in the same situation. I will be leaving Switzerland in 2022 to live in the EU so I have been filling up all my previous years gaps (buy-ins) in my 2b pillar (extra-mandatory). Literally the best 3-year investment as my marginal tax rate is quite high.

          Would I also be able to access my 2a pillar (mandatory 2 pillar) in case of being self-employed in my new country?

          thank you, Adam

    2. It’s pretty much a moot point because you can transfer to a vested benefits which is properly invested rather than keep it in your workplace pension where de facto you are subsidising the old people.

      So even if it is locked in it doesn’t matter really.
