How should you plan for major life events? (marriage, children and property)

Marriage, children and buying a home each change your taxes, pension and inheritance rights in Switzerland. Planning each step early keeps your finances on track.

Few decisions reshape your finances as much as getting married, starting a family or buying a home. Each one changes how you are taxed, who inherits from you, what your pension covers and how much you need to save. In Switzerland, where rules differ from canton to canton and property requires substantial equity, a little preparation makes a big difference. This article walks through the financial checkpoints for each event, explains how they interact and ends with a practical checklist you can use.

Marriage changes your tax situation, your property regime, your inheritance rights and your pension cover, all at once. Understanding each of these helps you avoid surprises in your first joint tax return or, later, in a difficult situation.

Taxes

Married couples in Switzerland are currently taxed jointly: their incomes and assets are added together and taxed at a higher progressive rate. For dual earner couples, this often results in a higher bill than two unmarried people with the same incomes would pay, a situation widely known as the marriage penalty.

This is set to change. On 8 March 2026, voters approved the introduction of individual taxation, under which each spouse will file their own return regardless of marital status. The reform will not apply immediately, as the cantons have until 1 January 2032 at the latest to adapt their tax laws. Until then, joint taxation remains the rule.

Matrimonial property regime

Unless you sign a marriage contract, you are automatically placed under the regime of participation in acquired property. Assets you owned before the marriage, plus gifts and inheritances, remain your own property. Everything you each earn and save during the marriage is acquired property, which is split equally if the marriage ends through divorce or death.

A marriage contract, signed in front of a notary, lets you choose a different arrangement:

• Separation of property: each spouse keeps everything they own and earn. This is often chosen by entrepreneurs or where one spouse has significant personal wealth.
• Community of property: most assets are pooled and shared. This is rarely used today.
• Modified participation in acquired property: the default regime is kept, but all acquired property is allocated to the surviving spouse on death. Many couples use this to protect the partner who lives longer.

Inheritance and pensions

Once married, your spouse becomes a statutory heir with a reserved share of your estate and is entitled to survivors' benefits from the state pension (AHV/AVS) and your pension fund. Be aware that the state pension for a married couple is capped at 150% of the maximum individual pension, so two high earners may receive less together than they would as single people.

What about couples who stay unmarried?

Unmarried partners have very few automatic rights. They do not inherit from each other without a will, may pay high inheritance tax as unrelated heirs and are usually only covered by a pension fund if they have registered as partners in writing. If you choose not to marry, a will, a cohabitation agreement and pension fund registrations are essential.

Preparing for a child means planning for a temporary drop in income, higher ongoing costs and new insurance and inheritance needs. Starting this planning during pregnancy gives you time to adjust your budget before the baby arrives.

How much income will you have during parental leave?

Swiss law provides 14 weeks of maternity leave and two weeks of leave for the other parent. During this time, the income compensation scheme pays 80% of your average earnings, up to a maximum daily allowance of CHF 220. Higher earners therefore see a noticeable drop in income, although some employers top up the statutory amount. Check your employment contract and company policy early.

Many parents also choose to reduce their working hours after the leave ends. A reduction from 100% to 60% affects not only your salary but also your pension fund contributions and your future retirement income, so it is worth calculating the long term impact.

How much will childcare and daily costs add up to?

Childcare is one of the largest expenses for Swiss families, and costs vary widely depending on your canton, commune and income. Before your child is born, research local nursery places, waiting lists and any subsidies available. On the positive side, you will receive monthly family allowances, which amount to at least CHF 215 per child, and you can claim tax deductions for children and for childcare costs.

Which insurance and documents should new parents review?

• Health insurance: register your baby with a health insurer within three months of birth so that cover applies retroactively from the day they are born.
• Risk cover: check your disability and death cover through your pension fund. If one parent's income supports the family, additional life insurance may be worth considering.
• Will: update your will and consider stating who you would like to look after your children if both parents die. The child and adult protection authority makes the final decision, but your wishes carry weight.
• Beneficiaries: update the beneficiary clauses in your Pillar 3a and life insurance policies.

How can you start saving for your children's future?

A regular savings plan, started early and kept small, can grow into a meaningful sum by the time your child turns 18. Thanks to compounding, the earlier you start, the more time returns have to build on themselves. Keep in mind that investing involves risk and that the value of investments can fall as well as rise.

To buy a home in Switzerland, you typically need at least 20% of the purchase price as equity and an income high enough that housing costs stay within about one third of your gross earnings. These rules come from the guidelines that Swiss lenders apply, and they shape every purchase decision.

How much equity do you need?

At least 20% of the purchase price must come from your own funds, and at least half of that (10% of the price) must be so called hard equity, such as savings, securities, gifts or Pillar 3a assets. You also need to budget for purchase costs, including notary fees, land registry fees and, in many cantons, property transfer tax. These usually add a few percent to the price.

How do lenders calculate affordability?

Banks test whether you could afford the property if interest rates rose sharply. They use an imputed interest rate, often around 5%, well above current market rates, and add maintenance costs of about 1% of the property value and the required amortisation.

These three events rarely happen in isolation, and the order in which they occur affects your rights and costs. Planning them together avoids gaps in protection.

• Buying before marrying: if you buy with a partner, decide how the property will be registered. In co-ownership, each partner owns a defined share they can sell or bequeath, while in joint ownership the property belongs to both partners together and decisions must be taken jointly. Without a will, an unmarried co-owner's share passes to their own family, not to their partner.
• Children and property: if a growing family needs more space, factor in the drop in income during parental leave before committing to a mortgage. Lenders will look at your current income, but you need to be comfortable with your future one.
• Marriage and pension withdrawals: once married, any withdrawal from your pension fund for a home purchase requires your spouse's consent, and the property becomes part of the matrimonial property calculation.

A short checklist for each event helps you cover the essentials without missing important deadlines.
