Lump sum or pension from your Swiss pension fund: what really decides it

As of October 2026. This article is general information, not advice on your personal situation.

Choosing between a pension and a lump sum is one of the largest financial decisions most people in Switzerland make, and it usually cannot be reversed. The pension gives you a fixed income for life. The lump sum gives you freedom, but it has to be invested and drawn down sensibly for decades, by you or by someone you appoint. Here is what to check before you decide.

What the law allows and what your fund decides

Under the BVG, the pension is the default (Art. 37 para. 1 BVG). You are entitled to take a quarter of your retirement assets as a one-off lump sum (Art. 37 para. 2 BVG). Whether you may take more, up to the full balance, depends on your pension fund's regulations (Art. 37 para. 4 BVG).

The regulations can also set a deadline for registering a lump-sum withdrawal. These deadlines differ from fund to fund, and missing one can mean you only get the pension. Read your fund's regulations early, ideally several years before you retire.

If you are married or in a registered partnership, the payout requires your spouse's or partner's written consent (Art. 37a BVG).

Reference age and early retirement

The reference age in occupational pensions is the same as for AHV: 65. Women born between 1961 and 1963 have a slightly lower transitional reference age under the AHV 21 reform. The BVG allows early drawing from 63, and fund regulations may permit retirement from 58 (Art. 13 BVG, Art. 1i BVV 2).

How each option is taxed

A pension from your pension fund is fully taxable as income every year (Art. 22 DBG). It is added to your other income, such as your AHV pension and investment returns, and taxed at the resulting rate.

A lump sum is taxed separately from your other income, and only once. For direct federal tax, the rate is one fifth of the ordinary scale (Art. 38 DBG). Cantons also tax capital benefits on their own (Art. 11 para. 3 StHG) but set their own rates, so the tax bill varies widely between cantons.

Two points that are easy to miss:

• At federal level, all pension capital paid out in the same year is added together, and for married couples this covers both spouses. The canton of Aargau, for example, does the same. Cantonal rules differ in the details.
• Once paid out, the money is ordinary wealth. It is subject to wealth tax, and interest and dividends on it are taxable income.

There is no general answer to whether the lump sum or the pension is cheaper in tax terms. It depends on your canton, the size of your assets, your other income and how long you live.

Buy-ins: the three-year lock-up

If you have made a voluntary buy-in, the benefits resulting from it cannot be withdrawn as a lump sum for the following three years (Art. 79b para. 3 BVG). Tax authorities apply this strictly. The Thurgau tax administration, for instance, treats a lump-sum withdrawal within three years of a buy-in as a purely tax-driven placement and refuses the deduction; if the assessment is already final, it opens a back-tax procedure.

If you are planning a lump sum, finish any buy-ins at least three years beforehand. If you withdrew money early for home ownership, voluntary buy-ins are only possible once that withdrawal has been repaid (Art. 79b para. 3 BVG).

Longevity: the risk the pension takes off your hands

The pension pays for as long as you live. A lump sum lasts as long as it lasts. According to the Federal Statistical Office, men aged 65 in 2025 could expect on average another 20.7 years, women 23.2 years. Those are averages, and many people live considerably longer.

With a pension, the fund carries this risk. With a lump sum, you do. The reverse also holds: if you die early, the remaining capital goes to your heirs. With a pension, usually only a surviving spouse receives a survivor's pension, by law at least 60 percent of the retirement pension (Art. 21 para. 2 BVG), and some regulations provide more.

The conversion rate

Your pension equals your assets multiplied by the conversion rate. The statutory minimum of 6.8 percent applies only to the mandatory BVG portion (Art. 14 BVG). Many funds apply a lower, so-called enveloping rate to the entire balance. Your pension certificate shows the pension you will actually receive.

Inflation: the pension's weak spot

Pension fund retirement pensions are adjusted to prices only if the fund's finances allow it; the governing body decides each year (Art. 36 para. 2 BVG). There is no automatic inflation link. Inflation was low in 2025 at 0.2 percent (FSIO/OAK BV), but small annual rates add up over 20 or 25 years.

An invested lump sum can in principle keep pace with inflation if part of it is held in real assets such as equities or property. The price is that its value fluctuates.

A worked example

Illustration with round, assumed figures. It is not a calculation of your case.

Suppose you retire at 65 with retirement assets of CHF 800,000 and your fund applies an enveloping conversion rate of 5.4 percent. Your pension would be CHF 43,200 a year.

• Pension: Ignoring interest and tax, the pension payments add up to the capital after about 18.5 years, at around age 83.5. If you live longer, you receive more in total.
• Inflation: With prices rising 1 percent a year, the unadjusted pension is worth about CHF 35,400 in today's money after 20 years. At 2 percent, about CHF 29,100.
• Lump sum: You receive CHF 800,000, pay the capital benefit tax once and invest the rest. How long it lasts depends on returns, withdrawals and your lifespan.

The pension pays off mainly with a long life and low inflation. The lump sum suits a shorter horizon, higher inflation, or a stronger wish for flexibility and something to pass on.

Partial withdrawal: combining both

You do not have to pick one side. Many funds allow a mix, for example half as pension and half as capital. The pension then covers fixed costs, while the capital serves as a reserve.

Since 2024 the BVG sets clearer rules for drawing benefits in stages (Art. 13a BVG):

• The pension can be drawn in up to three steps; a fund may allow more.
• Capital can be withdrawn in at most three steps. All lump-sum withdrawals within one calendar year count as one step.
• The first partial withdrawal must be at least 20 percent of the retirement benefit, unless the fund allows a lower share.
• Before the reference age, the share drawn may not exceed the reduction in salary (Art. 13b BVG).

Questions to settle first

• What are your fixed costs, and how much of them do the AHV and pension fund pensions cover?
• How comfortable are you with market swings if your capital is invested?
• How much does it matter to you that money passes to children or other heirs?
• What would the capital benefit tax be in your canton, including with staggered withdrawals?
• Have you made buy-ins in the last three years, or are you planning any?

If a lump sum is on the table, the next question follows quickly: who will invest it? Thinking Steps helps people with investable assets of CHF 500,000 or more find a suitable private bank or independent wealth manager.

Key points

• You can take at least a quarter of your retirement assets as a lump sum; more only if your fund's regulations allow.
• Registration deadlines are set in the regulations; married members need written spousal consent.
• A lump sum is taxed once and separately, at one fifth of the scale for federal tax; a pension is fully taxable every year.
• After a buy-in, a three-year lock-up applies to lump-sum withdrawals.
• The pension protects against longevity but is not automatically linked to inflation.
• A partial withdrawal combines both; capital can be taken in at most three steps.
