# Swiss Tax Optimization 2026: Deductions, Wealth Tax & Imputed Rental Value

**Quick answer:** Yes. Crypto balances on 31 December are valued at the official year-end rates published by the Federal Tax Administration and added to taxable wealth.

Switzerland has 26 cantonal tax systems, but the deduction logic is largely shared. A well-prepared return can save thousands of francs — here's the playbook.

## The deductions everyone should claim

  - **Pillar 3a contributions** — up to CHF 7,258 (employees) deductible from federal and cantonal income.

  - **Professional expenses** — commuting (capped at CHF 3,200 federally), meals at work, training & continuing education up to CHF 12,900.

  - **Pillar 2 buy-ins** — fully deductible, often the biggest single lever for high earners.

  - **Health insurance & medical costs** — premiums up to a cantonal cap, medical bills above 5% of net income.

  - **Childcare** — up to CHF 25,500 federally per child since 2023.

  - **Donations** to recognized charities, typically up to 20% of net income.

  - **Mortgage interest and maintenance** for property owners.

## Wealth tax (Vermögenssteuer)

Switzerland is one of the few countries that still levies a tax on net worth. It's purely cantonal/communal — federal level is zero. Rates and exemptions vary widely:

  - **Zug** — among the lowest, ~0.14% top rate.

  - **Geneva** — among the highest, >1% effective for large estates.

  - Tax-free allowance: typically CHF 70,000–200,000 depending on canton and family situation.

Pillar 2 and Pillar 3a balances are **not** counted in taxable wealth. Real estate is valued at the official tax value (often well below market). Brokerage accounts, crypto and bank balances on 31 December are.

## Eigenmietwert (imputed rental value)

Owners of their primary residence must add an imputed rent — usually 60–70% of market rent — to taxable income. In return, mortgage interest and maintenance costs are deductible.

In late 2025 the Swiss Parliament approved the **abolition** of the Eigenmietwert, with a popular vote completing the reform. From the planned implementation, mortgage interest deduction will largely disappear too — making the system cleaner but raising taxes for newly indebted buyers. Watch the official cantonal communications for the start date.

## Practical playbook

  - Maximise Pillar 3a every year — set up a standing order in January.

  - Plan Pillar 2 buy-ins across multiple years to keep marginal benefit high.

  - Pay your invoices for medical, training and donations **before 31 December** to land them in the right tax year.

  - Keep digital receipts categorized — Finch tags deductible expenses automatically.

## FAQ

**Are crypto holdings part of Swiss wealth tax?**

Yes. Crypto balances on 31 December are valued at the official year-end rates published by the Federal Tax Administration and added to taxable wealth.

**Will mortgage interest still be deductible after Eigenmietwert is abolished?**

Largely no. The reform package removes the imputed rental value and at the same time eliminates most mortgage interest and maintenance deductions for primary residences.
