In short

Dual-income couples in Switzerland are jointly assessed for tax, which is what produces the well-known 'marriage penalty' on two similar high incomes - the combined income jumps a bracket that two singles would not have hit. As of 2025, the upside is just as large: two full pillar 3a contributions (up to 2 × CHF 7'258), substantially higher joint mortgage capacity, a high realistic savings rate while childcare costs are zero, and the chance to lock in protection and pension buy-ins before a possible career break for a child.

What you face

What dual-income couples have to figure out

  1. 01

    The 'marriage penalty' on two similar incomes

    Joint federal and cantonal assessment can push two equal-earner spouses into a steeper bracket than the same two incomes filed singly. Two-earner deductions soften it, but never fully neutralise it.

  2. 02

    Two pillar 3a accounts - one strategy

    Each working spouse with a pillar 2 can contribute up to CHF 7'258 in 2025 - in total over CHF 14'500 of fully tax-deductible retirement savings per household, often in invested 3a accounts rather than cash.

  3. 03

    Combined borrowing power for a mortgage

    Two salaries dramatically improve the 5% notional affordability test, often pushing realistic purchase prices into the CHF 1.5-2 m range - if the equity and pillar 2 buy-in strategy is set up correctly.

  4. 04

    A high savings rate while costs are low

    Pre-children, household fixed costs (one rent, KVG for two, no childcare) leave room for a 30-50% savings rate. We help direct it - 3a, pension buy-ins, taxable investments - instead of letting it sit in CHF current accounts.

  5. 05

    Planning for a possible career break

    If one partner may stop or go part-time later (for a child, study or relocation), the right moves now - splitting pillar 3a, building protection on the lower earner, pension buy-ins on the higher earner - are far cheaper than fixing them after the fact.

  6. 06

    Joint vs separate banking and ownership

    Matrimonial-property regime (default: Errungenschaftsbeteiligung), joint vs separate accounts, who legally owns the future home - boring decisions that quietly decide divorce maths and tax efficiency.

  7. 07

    Protection sized for two incomes

    Cover is not just for the higher earner. If one partner stops working for any reason, the household plan must still survive on the remaining salary - which usually means term-life and disability on both.

FAQ

Dual-income couple questions we hear most often

How bad is the Swiss marriage penalty for two earners?
On two similar high incomes, joint assessment can add a clearly visible amount of federal tax compared with filing as two singles - typically a few thousand francs per year on combined incomes in the CHF 200-400k range, varying by canton. Two-earner deductions and household allowances soften the effect but don't fully neutralise it. A federal reform has been debated for years.
Can we both contribute the full pillar 3a?
Yes, provided each of you has AHV-liable earned income and is covered by a pillar 2. Each spouse contributes to their own 3a account up to CHF 7'258 in 2025 - the limit is per person, not per couple - and both contributions are deductible from your joint taxable income.
How much can a DINK couple borrow for a Swiss home?
Banks size mortgages so that the notional cost (5% interest + ~1% maintenance + amortisation to 65% LTV in 15 years) does not exceed roughly one third of gross household income. With two solid salaries, that often translates into a realistic purchase price of 5-6 times combined gross annual income, on top of the required 20% equity (at least 10% in 'hard' cash).
Should we use joint or separate bank accounts?
There is no Swiss tax difference - couples are assessed jointly either way. Pragmatically, most DINK couples we work with run one joint account for shared fixed costs and savings, plus an individual account each. Investment and pillar 3a accounts are always individual by law.
We might have a child in 2-3 years - what should we do now?
Use the dual-income window deliberately. Max both 3a accounts, consider pillar 2 buy-ins on the higher earner (often the most tax-efficient single move), put protection in place on both partners while underwriting is easy, and build a 6-12 month cash buffer in CHF to cover maternity income gaps and possible part-time conversion. We model the budget for the year a child arrives so it isn't a surprise.
Does it make sense to do a pillar 2 buy-in as a couple?
Buy-ins are individual, not joint, and most valuable on the higher-earning spouse in their peak-tax years - typically 45+ - because the deduction works against the top marginal bracket. As of 2025, capital withdrawn from pillar 2 within 3 years of a buy-in cannot be taken as a lump sum without tax recapture, so timing relative to a planned property purchase or early retirement matters.
