Lump Sum or Pension? How to Decide at Retirement

At 63 or 65, the biggest financial decision of your life shows up, and most people make it with surprisingly little preparation: pension or lump sum? Your pension fund will either pay you a monthly pension for the rest of your life, or pay out your entire retirement savings in one go, often a sum between CHF 200,000 and well over a million francs. When exactly you have to decide is set out in your pension fund's regulations, often one to three years before retirement. Once you've chosen, you can't undo it afterward.

There's a lot more riding on this than just the number on your pension certificate: your tax bill, how long your money needs to last, and how much responsibility you want to take on yourself. We break down how a pension and a lump sum differ, when each option tends to pay off, and how staggering your withdrawal can save you several thousand francs in tax.

Pension or Lump Sum: What You're Actually Choosing

With the pension option, your pension fund converts your accumulated retirement savings into a lifelong monthly pension using what's called the conversion rate. The statutory minimum conversion rate remains unchanged in 2026 at 6.8% on the mandatory BVG portion of your savings, which works out to CHF 6,800 in annual pension per CHF 100,000 of retirement capital. On the non-mandatory portion, however, many pension funds apply a noticeably lower rate, often between 5% and 5.5%. Your actual, effective conversion rate is shown on your pension certificate, and for many funds it differs noticeably from the legal minimum.

Your AHV pension, by the way, keeps running independently of this and is never paid out as a lump sum. For how to calculate it, see AHV Pension Explained: What You'll Actually Receive in 2026. This article focuses exclusively on your pension fund and your pillar 3a.

With the lump sum option, you receive your entire retirement savings, or part of it, as a one-time payment. From that point on, you carry the responsibility yourself: for the investment return, for the risk of outliving your savings, and for making sure the money lasts. Many pension funds also allow a middle path, a partial lump sum, for example half as a pension and half as a lump sum. How much of a partial withdrawal your fund's regulations allow varies from fund to fund, so ask.

When the Pension Pays Off: The Break-Even Point

A worked example makes this more concrete. Take retirement savings of CHF 500,000 and a conversion rate of 6%, which gives you an annual pension of CHF 30,000. Looking purely at the capital involved, after about 17 years of pension payments you'll have received as much in total as your original capital, that's the simplest break-even point.

If you invest the capital yourself instead and earn a moderate return, your comparison figure keeps growing in the meantime, which pushes the real break-even point noticeably further out, often toward 20 years or more. If you live well beyond that point, the pension turns out, in hindsight, to have been the better choice. If you die earlier, the lump sum would have been better, at least for your heirs, since unused pension capital mostly reverts to the pension fund rather than your estate.

That's exactly the core problem: you don't know your own life expectancy in advance. The pension takes that risk off your hands entirely, you're guaranteed an income for as long as you live, whether that means age 68 or 98. The lump sum, in exchange, gives you flexibility and the option to pass on unused wealth to your heirs. Our pension or lump sum calculator lets you run both scenarios with your own numbers, including taxes, an assumed return and life expectancy.

Tax: The Biggest Difference Between Pension and Lump Sum

With the pension, you pay regular income tax on the amount you receive every year, combined with your other income, at your normal tax rate. If your pension runs for 20 or 25 years, you pay tax on it the whole time, but the capital itself no longer shows up on your tax return once it arrives as pension income, since it's already been spent.

With the lump sum, it works the other way around: you pay a one-time lump-sum withdrawal tax, calculated separately from your other income, at a reduced rate that is still progressive within that separate tax. How much it comes to depends heavily on your canton of residence in the year of the payout and varies enormously between cantons. On a payout of CHF 500,000, the tax typically ranges from around CHF 25,000 to CHF 50,000 depending on the canton, and on CHF 1,000,000 from around CHF 50,000 to CHF 110,000. If you live in a tax-friendly canton such as Schwyz, Zug or Obwalden, you benefit considerably more than in cantons such as Geneva, Vaud or Bern. Because your place of residence in the year of the payout is what counts, it's worth checking the lump-sum withdrawal tax in your current or future canton before you apply for the payout.

What Happens to Your Family: Spouses and Children

The choice between pension and lump sum doesn't just affect you. If you choose the pension, your spouse automatically receives a spouse's pension after your death, at least 60% of your last pension under the mandatory BVG minimum, and many pension fund regulations provide for more than that. If you have children who are minors or still in education, an orphan's pension is added on top. This protection kicks in automatically, with no separate policy or application needed.

With the lump sum, that automatic protection disappears. If you die shortly after retiring and have already spent or poorly invested a large part of the capital, your family is left without the spouse's pension they would otherwise have had. That's exactly why the law adds an extra safeguard for lump-sum withdrawals: if you're married, the payout requires your spouse's written, notarized consent. This requirement doesn't apply to the pension option, because your family is automatically protected there anyway.

This isn't just a formality, it's a genuine protection mechanism. Before your partner signs, it's worth having a joint conversation about how you'll handle responsibility for the capital if one of you were to die, for example through a separate term life policy or a clear investment and spending plan.

Staggering Your Withdrawal: How to Break the Tax Progression

Because the lump-sum withdrawal tax is progressive, a simple rule applies: the more you withdraw in a single year, the higher the tax rate on the entire amount. If you withdraw your retirement savings over several years instead, each portion is taxed on its own and the progression breaks.

For pillar 3a, this is relatively easy to arrange, provided you've kept several accounts over the years. For how pillar 3a works in general, see Pillar 3a: Everything You Need to Know in 2026. The common rule of thumb for how many accounts to open: start a new pillar 3a account once your current one reaches around CHF 30,000 to 50,000. With a maximum contribution of CHF 7,258 per year in 2026 with a pension fund, or up to CHF 36,288 without one, you'll easily build up three to five accounts over a full career without any extra effort.

At retirement, you then withdraw these accounts not all in the same calendar year, but spread across several years, which noticeably lowers the tax on each individual withdrawal. A withdrawal is possible at the earliest five years before your ordinary reference age, and, as long as you keep working, can be deferred by up to five years beyond it, until age 70 at the latest.

Staggering the lump sum from your pension fund is harder, because many funds' regulations only provide for a single withdrawal date. Some funds do allow a partial withdrawal in the years before ordinary retirement, for example as part of a gradual reduction in your working hours. Whether and how that works at your fund is set out in its pension regulations, and when in doubt, a call to your pension fund administration will clarify it.

The Planned Tax Increase That's Off the Table for Now

As part of Relief Package 27 (Entlastungspaket 27), the Federal Council wanted to increase the tax on lump-sum withdrawals from the second and third pillar, aiming for around CHF 190 million a year in additional federal revenue. For anyone planning to retire in the next few years, that was a legitimate cause for concern. Parliament rejected this proposal in March 2026, however, so the currently favorable tax treatment of lump-sum withdrawals remains in place for now.

That doesn't change the fact that tax law can shift again in principle. If you're planning your retirement several years ahead, it's worth periodically checking whether the current rules have changed, rather than relying blindly on a figure you calculated once.

Practical Tip: Start Running the Numbers 5 to 10 Years Ahead

Don't wait until the last year before retirement to decide. Request an up-to-date pension certificate 5 to 10 years in advance and check your pension fund's actual conversion rate, not just the statutory minimum. If you currently have only one pillar 3a account, open a second or third one now so you're actually able to stagger your withdrawal later. If you're still several years from retirement, you can also save tax in the meantime with a voluntary pension fund top-up, well before the withdrawal itself becomes relevant. Run your own numbers through the pension or lump sum calculator as well, ideally with several assumptions about life expectancy and returns. And talk to your pension fund early about the deadlines for making your decision.

Conclusion

There's no universally right answer to the pension-or-lump-sum question, too much depends on your health, your family situation and how willing you are to manage money yourself. What almost always pays off, though: keep several pillar 3a accounts, stagger your withdrawal, and run the numbers early instead of deciding at the last minute. Between the best and the worst execution of the very same underlying decision often sits several tens of thousands of francs in tax. With a bit of lead time, that's a gap you can almost always close.
