Annuity or lump sum: what are the tax implications of each withdrawal option?
The choice between an annuity and a lump-sum withdrawal is explored in detail in a previous episode. However, it is important to understand that these two options are not subject to the same tax treatment.
An annuity is taxed as income
Pension benefits paid in the form of an annuity are included in your annual taxable income. This applies in particular to state pension benefits and occupational pension payments.
While an annuity provides the security of a regular income throughout retirement, it remains subject to taxation every year. The higher the combined amount of your pension income and other recurring sources of income, the greater the potential tax burden.
In addition, annuity payments are rarely fully indexed to inflation, meaning that your purchasing power may gradually decline over time.
An annuity can therefore be an effective way to secure a steady income, but its tax impact and long-term evolution should be taken into account when planning for retirement.
A lump sum is taxed when it is withdrawn
By contrast, benefits withdrawn as a lump sum are taxed at the time of payment under a specific tax regime separate from ordinary income taxation.
Once this tax has been paid, the capital becomes part of your private wealth. Any income subsequently generated by this capital — such as interest, dividends, rental income or gains resulting from an investment strategy — will be taxed according to the relevant rules.
Beyond tax considerations, choosing a lump-sum withdrawal can also provide greater financial flexibility during the early years of retirement. In Switzerland, healthy life expectancy at age 65 is currently around 15 years. During this period, retirees often have more plans and projects, travel more frequently, devote more resources to leisure activities, or undertake significant investments.
This reality leads many people to favour at least a partial lump-sum withdrawal in order to have greater financial resources available during the early years of retirement, when spending needs and personal projects are often at their highest.
The key consideration is therefore not simply whether to choose an annuity or a lump sum, but also the timing of withdrawals, the amount withdrawn and the way this capital will be integrated into your overall wealth structure and long-term life plans.
Why plan several years before retirement?
As retirement approaches, many people simultaneously hold:
-
assets in their pension fund;
-
one or more pillar 3a accounts;
-
and, in some cases, vested benefits assets.
These different sources of retirement savings are not all taxed in the same way. Annuities are taxed annually as income, whereas retirement capital is subject to a specific tax regime when it is withdrawn.
Waiting until the final year before retirement often limits planning opportunities. Starting the process early makes it possible to coordinate withdrawals, avoid excessive concentrations of capital over a short period and incorporate tax considerations into a coherent wealth-planning strategy.
The objective is not simply to reduce taxes, but to preserve more capital for the projects and ambitions you wish to pursue during retirement.
Pension fund buy-backs: a tax-planning opportunity to consider early
Voluntary buy-backs into a pension fund can help fill pension gaps while also providing tax advantages in certain circumstances. Contributions can generally be deducted from taxable income, potentially resulting in significant tax savings for individuals in higher tax brackets towards the end of their careers.
In many cases, it is preferable to spread pension fund buy-backs over several years rather than making a single large contribution. This approach often improves overall tax efficiency while allowing the amounts invested to be gradually integrated into a broader retirement strategy.
However, buy-backs should not be viewed solely from a tax perspective. When a lump-sum withdrawal is planned at retirement, buy-backs should be carefully structured well in advance. As a rule, a buy-back should be made at least three years before the withdrawal of capital in order to benefit from the related tax deductions.
Before making a buy-back, it is important to consider:
-
your retirement horizon;
-
your current tax rate;
-
your future liquidity needs;
-
whether you intend to receive an annuity, a lump sum or a combination of both;
-
the structure of your pension fund;
-
your estate and wealth-planning objectives.
A pension fund buy-back should not be viewed solely as an immediate tax-saving opportunity. It should form part of a broader reflection on your retirement income, future needs and overall wealth structure.
Pillar 3a: more than just a savings vehicle
Why open multiple pillar 3a accounts?
Pillar 3a contributions are deductible from taxable income during your working life, which is why they are often viewed primarily as a tax-saving tool.
However, their tax impact does not end once the savings phase is over.
Upon retirement, pillar 3a assets are subject to a specific tax when withdrawn. If all assets are held in a single account, the entire amount must generally be withdrawn at once, limiting planning flexibility.
Spreading savings across several pillar 3a accounts can allow withdrawals to be staggered over time, where permitted by applicable regulations. This approach offers greater flexibility when coordinating pillar 3a withdrawals with those from a pension fund or vested benefits assets.
The tax advantage therefore lies in better controlling the timing of withdrawals rather than concentrating all capital withdrawals within a single period.
Abolition of the imputed rental value
As explained in the previous episode, the abolition of the imputed rental value represents a significant change in the Swiss tax landscape.
The gradual disappearance of certain tax deductions linked to property ownership could encourage taxpayers to make greater use of alternative tax-planning opportunities.
Depending on your situation, it may be worth adjusting both the timing and amount of your pillar 3a contributions in order to preserve future buy-back opportunities. As discussed in the second episode of this 360 series, it is possible since 1 January 2026, under certain conditions, to make pillar 3a buy-backs.
Such a strategy may allow tax deductions to be concentrated in years when your taxable income is highest, thereby maximising their potential tax benefit.
Vested benefits: an often overlooked tax-planning tool
Vested benefits are generally associated with a change of employer or a career break. However, as retirement approaches, they can become an important wealth-planning and tax-planning tool.
Assets transferred to a vested benefits foundation continue to form part of your retirement savings and should therefore be assessed in the same way as your pension fund assets or pillar 3a savings.
Why should vested benefits be included in your retirement strategy?
Vested benefits directly affect:
-
the capital available at retirement;
-
the timing of pension withdrawals;
-
the tax treatment applied when benefits are paid out;
-
the overall structure of your wealth;
-
your estate-planning objectives.
Vested benefits should therefore not be viewed simply as a temporary holding account. As retirement approaches, they can play an important role in structuring withdrawals and optimising your tax position.
What are the tax advantages of vested benefits?
Vested benefits assets benefit from a specific tax treatment:
-
the capital is not included in taxable wealth while it remains within the vested benefits structure;
-
returns generated are not taxed as ordinary income during that period;
-
upon withdrawal, the capital is taxed separately from other sources of income.
These characteristics help explain why the timing of withdrawals, the amount withdrawn and the structuring of vested benefits assets should be reviewed several years before retirement.
Splitting: a strategy that should be considered early
Some individuals choose to divide their retirement assets between two separate vested benefits accounts when leaving a pension fund. This approach, commonly referred to as splitting, can provide greater flexibility when planning future withdrawals.
It can help:
-
stagger withdrawals over time and reduce the tax burden through the progressive taxation of lump-sum pension benefits;
-
better coordinate different sources of retirement capital;
-
avoid concentrating all retirement capital in the same tax year;
-
adapt a wealth strategy to changing needs.
However, this decision must generally be taken at the time of transfer from the pension fund. Once assets have already been placed in a vested benefits solution, flexibility may be more limited.
Common mistakes to avoid
Waiting until the last minute
Many tax optimisation opportunities need to be planned several years before retirement. Pension fund buy-backs, the structuring of pillar 3a savings or the allocation of vested benefits assets cannot be improvised a few months before retirement.
The earlier the planning process begins, the easier it becomes to coordinate different retirement assets and avoid rushed decisions.
Looking at each product separately
Preparing for retirement does not mean analysing your pension fund, pillar 3a accounts, vested benefits assets and investment portfolio independently.
These different elements interact with one another. A lump-sum withdrawal, a higher annuity, a pension fund buy-back or a pillar 3a withdrawal may all affect your taxable income, taxable wealth or liquidity position.
The goal is therefore to obtain a consolidated view of your wealth in order to understand the tax implications of each decision.
Focusing solely on tax savings
Tax considerations are important, but they should never be the sole criterion for decision-making.
A tax-efficient strategy may prove unsuitable if it excessively reduces your liquidity, compromises your financial security or does not align with your estate-planning objectives.
The ultimate goal is to preserve your standard of living, organise your future sources of income and structure your wealth in a coherent manner.
Key takeaways
Preparing for retirement involves much more than simply accumulating capital. It also requires anticipating how that capital will be withdrawn, taxed and integrated into your overall wealth structure.
Annuities, lump-sum withdrawals, pension fund and pillar 3a buy-backs, and vested benefits assets do not all have the same tax consequences. Successfully coordinating these elements is what enables a more efficient retirement strategy.
Effective retirement planning rarely relies on a single lever. Rather, it is the combination of several well-structured decisions, made sufficiently early, that helps preserve more capital, optimise taxation and approach retirement with greater peace of mind.
