Individual Taxation Switzerland 2026

What Is the Marriage Penalty?

The so-called marriage penalty refers to a phenomenon in the Swiss tax system where married couples with two similar incomes are taxed more heavily than unmarried couples (cohabiting couples). This is due to the joint taxation of married couples (spousal taxation).

On March 8, 2026, Switzerland will vote on the introduction of individual taxation. This reform would permanently abolish the marriage penalty.

What Is Individual Taxation?

With individual taxation, every person – regardless of marital status – is taxed separately. This means:

• Spouses file separate tax returns
• Each income is taxed individually
• No combination of incomes

Current System vs. Individual Taxation

Who Benefits from Individual Taxation?

Winners

• Dual-earner married couples with similar incomes – Tax burden drops significantly
• Working women – Increased incentive to work more (no high tax progression on second income)
• Same-sex married couples – Same treatment as heterosexual couples

Losers

• Single-earner married couples – Higher tax burden as splitting advantage disappears
• Couples with large income differences – Less equalization
• Retired married couples with one pension – Loss of splitting

Example Calculations

Example 1: Dual Earners (both CHF 100,000)

Result: The couple saves approximately CHF 6,500 per year.

Example 2: Single Earner (CHF 200,000 / CHF 0)

Result: The couple pays approximately CHF 6,000 more per year.

Using Tax Optimization

Regardless of the referendum outcome, you can optimize your taxes through targeted measures:

1. Maximize Pillar 3a

Use the maximum deduction of CHF 7,258 (employees) or CHF 36,288 (self-employed). With individual taxation, each partner can deduct the full amount.

2. Optimize Savings Account

Interest income is also taxed individually. Compare the best interest rates.

Impact on Retirement Planning

Individual taxation would also affect retirement planning:

Pillar 3a

• Pro: Each partner can contribute independently
• Neutral: Maximum amount remains the same
• Pro: Staggered withdrawal becomes easier (separate accounts)

Pension Fund (Pillar 2)

• Neutral: No direct changes
• Important: Buy-ins still individually deductible

FAQ

When Would Individual Taxation Take Effect?

If the referendum passes on March 8, 2026, the Federal Council must first draft implementation legislation. An introduction by 2028 or 2029 is realistic at the earliest.

How Are Children Taxed?

Child deductions will likely be split or assigned to one parent. The exact regulation will be defined in the implementation law.

What Happens with Joint Investment Income?

Investment income (interest, dividends) from joint assets will be split 50/50 and taxed individually.

Should I Get Married or Is Cohabitation Better?

With individual taxation, marital status would no longer matter for taxes. The decision can then be made purely based on other criteria (inheritance law, pension planning).

Conclusion

The referendum on individual taxation on March 8, 2026 could fundamentally change the Swiss tax system. Dual-earner couples would benefit, while single-earner families would face higher burdens.

Regardless of the outcome, you should keep an eye on your tax optimization and utilize options like Pillar 3a or savings accounts.
