Individual Taxation Switzerland 2026: Reform Status

Key Takeaways (as of May 2026)

• The popular initiative "For tax fairness for all - initiative for individual taxation", submitted in 2022 by the FDP Women, demands separate assessment of married spouses instead of the joint spousal assessment.
• The Federal Council adopted its dispatch on individual taxation in 2024 as an indirect counter-proposal. The matter is in parliamentary deliberation between 2025 and 2026.
• Dual-income married couples could save roughly CHF 600 to 1,500 per year in federal direct tax according to estimates by the Federal Tax Administration (FTA). Single-income couples would generally pay more.
• Six cantons (BL, GE, GR, NE, VD, VS) already apply elements of separate assessment at the cantonal level.
• Earliest possible entry into force in 2028, subject to the parliamentary process and any referendum.

What Is the Marriage Penalty?

The marriage penalty describes a phenomenon in the Swiss tax system: married couples with two similar incomes pay more federal direct tax than two unmarried cohabiting partners with the same total income. The reason lies in joint spousal taxation under the Federal Direct Tax Act (DBG, Art. 9 and 13) and the Federal Act on the Harmonisation of Direct Taxes (StHG, SR 642.14): both spouses' incomes are added together and subject to progression as a single unit. The couple therefore enters a higher tax bracket than a single person would for the same individual income.

Under individual taxation, each person is assessed separately, regardless of marital status. This means:

• Each spouse files their own tax return.
• Each income is taxed individually using the standard rate schedule.
• No more combining of incomes.

Comparison: Joint Spousal Taxation vs. Individual Taxation

| Aspect | Joint spousal taxation (today) | Individual taxation (planned) | |--------|--------------------------------|-------------------------------| | Tax return | Joint filing | Separate per person | | Tax brackets | Higher bracket through aggregation | Each person taxed in their own bracket | | Dual-income couples | Disadvantaged (marriage penalty) | Treated like cohabiting couples | | Single-income couples | Splitting advantage | Tendentially higher taxes | | Cohabiting couples | Already taxed individually | Same rules |

Who Wins, Who Pays More?

The winners

• Dual-income married couples with similar incomes see their tax burden fall, as each income is taxed in its own bracket.
• Second earners (often women) face a lower marginal tax rate on additional income, increasing the incentive to work a higher percentage of full time.
• Same-sex married couples receive the same treatment as all other married couples.

Who pays more

• Single-income married households lose the splitting advantage, with the tax burden potentially rising unless compensation mechanisms apply.
• Couples with a large income disparity lose part of the levelling effect between partners.
• Retired married couples with a single pension lose the splitting effect, with consequences varying by canton.

Example Calculations for Dual-Income Couples

The following examples relate to federal direct tax and are based on the modelling in the Federal Council's 2024 dispatch. Cantonal and municipal taxes vary substantially by place of residence.

Example 1: Dual income (CHF 100,000 + CHF 100,000)

| System | Federal direct tax (approx.) | Difference | |--------|-----------------------------|------------| | Joint assessment (today) | CHF 9,200 | - | | Individual taxation (planned) | CHF 7,800 | about CHF 1,400 less |

Reading: for symmetric mid-range incomes, the saving in federal direct tax is roughly CHF 600 to 1,500 per year. Cantonal and municipal taxes can add to or modify the effect depending on the canton.

Example 2: Single income (CHF 200,000 + CHF 0)

| System | Federal direct tax (approx.) | Difference | |--------|-----------------------------|------------| | Joint assessment (today) | CHF 11,500 | - | | Individual taxation (planned) | CHF 13,200 | about CHF 1,700 more |

Reading: in a classic single-income household the splitting advantage disappears. Parliament is therefore debating compensation mechanisms such as higher child or household deductions.

The examples are simplified. Actual figures vary by canton, municipality, religious affiliation and personal situation.

Where Does the Reform Stand in Spring 2026?

As of May 2026, individual taxation is not yet in force. The political process is advancing on two parallel tracks.

1. Popular initiative "For tax fairness for all – initiative for individual taxation" (FDP Women, submitted 2022): demands separate spousal taxation at the constitutional level.
2. Federal Council indirect counter-proposal (dispatch 2024): implements the objective at the statutory level without amending the constitution. The matter is being treated by the two Chambers in 2025-2026.

According to the current timetable, parliamentary deliberation will continue until late 2026. If Parliament adopts the counter-proposal and the initiative is withdrawn, an entry into force no earlier than 2028 is realistic. If a referendum is held against the counter-proposal or the initiative goes to a popular vote, the timeline will shift accordingly.

Supporters and Opponents (as of May 2026)

Supporters:

• FDP, Green Liberals, Greens, SP and the majority of the Centre party
• Swiss Trade Union Federation (SGB)
• Federation romande des consommateurs (FRC) and Swiss Consumer Forum
• Swiss Conference of Equal Opportunity Officers

Opponents or critical voices:

• SVP (mostly), parts of the Centre party
• alliance F – Federation of Swiss Women's Organisations on individual points
• Pro Familia Switzerland, which fears a heavier burden on single-income families.

Cantons That Already Apply Separate Assessment

Six cantons already apply elements of separate assessment for cantonal and municipal taxes — without going as far as pure individual taxation:

• Basel-Landschaft (BL)
• Geneva (GE)
• Graubünden (GR)
• Neuchâtel (NE)
• Vaud (VD)
• Valais (VS)

These cantons use splitting or full-splitting models that move closer to individual taxation. Federal direct tax remains based on joint assessment for now.

Tax Optimisation You Can Use Today

Regardless of the reform timeline, the main tax-optimisation levers stay the same.

1. Maximise Pillar 3a Contributions

Use the maximum deduction of CHF 7,258 for employees with a pension fund or CHF 36,288 (20% of net self-employed income) for self-employed persons without a pension fund (2026 figures). Already today each spouse can deduct their own maximum if both have earned income.

2. Pension Fund Buy-Ins

Voluntary buy-ins into the pension fund (Pillar 2) are fully deductible from taxable income. In a year with high income or a bonus, a well-timed buy-in breaks the progression. Mind the three-year blocking period before any capital withdrawal.

3. Optimise Savings Accounts and Investment Income

Under individual taxation, interest income will be split equally between the spouses. Already today, comparing savings rates can mean several hundred francs of difference per year.

4. Professional Expenses and Home Office

Professional expenses, continuing education and the home-office share remain deductible. Our cluster covers the practical details for filing in 2026.

Effects on Retirement Planning

Pillar 3a

• Advantage: each spouse can contribute independently — already the case today and unchanged under the reform.
• Neutral: the maximum contribution stays the same.
• Advantage: staggered withdrawal becomes easier because each person is taxed separately on their own accounts.

Pension Fund (Pillar 2)

• Neutral: no direct changes to ordinary pension-fund contributions.
• Important: voluntary buy-ins remain individually deductible for the spouse who pays them.

Frequently Asked Questions

When does individual taxation actually take effect?

As of May 2026 the reform is still in parliamentary deliberation. Even with a swift process, an entry into force no earlier than 2028 is realistic. A referendum or a popular vote on the initiative would push the timetable back.

How will children be taxed?

The Federal Council's dispatch proposes that child deductions be split equally or attributed to a single parent. The exact rules — including third-party childcare costs and maintenance payments — are still being refined in Parliament.

What happens to jointly held investment income?

Interest, dividends and other investment income from jointly held assets will be split 50/50 between the spouses and taxed individually. This mirrors current practice for cohabiting couples.

Should I marry now, or is cohabitation better?

Under individual taxation, marital status would no longer affect federal direct tax. The decision could be based on other criteria such as inheritance law, pension planning or social insurance. For now, current rules continue to apply.

Who benefits the most?

Dual-income married couples with similar incomes benefit the most. Depending on income level and canton, federal direct tax savings range from roughly CHF 600 to 1,500 per year. The effect can multiply once cantonal and municipal taxes are factored in.

Are transitional rules planned?

The exact transitional provisions will be defined in the implementing legislation and ordinances. For reforms of this scope, lawmakers typically allow several years of transition to avoid hardship cases.

What about cantonal and municipal taxes?

The reform affects federal direct tax and, via the StHG (SR 642.14), cantonal and municipal taxes. Six cantons — BL, GE, GR, NE, VD, VS — already use splitting models that come close to separate assessment.

Conclusion

Individual taxation would fundamentally restructure the Swiss tax system. The popular initiative "For tax fairness for all" and the Federal Council's indirect counter-proposal are under parliamentary deliberation between 2025 and 2026. Dual-income married couples can expect a relief of roughly CHF 600 to 1,500 per year on federal direct tax, while single-income households face a higher burden.

Regardless of the political timetable, tax optimisation already makes sense today: maximise Pillar 3a, consider pension-fund buy-ins, claim professional expenses and compare savings rates. To follow the political process, communications from the Federal Tax Administration (FTA) and the Federal Department of Finance (FDF) are good sources.
