How does Pillar 3a work and how much can I deduct in 2024?

Pillar 3a is Switzerland's voluntary, tax-advantaged private pension. Contributions are fully deductible from taxable income at federal and cantonal level. For 2024, the maximum deduction is CHF 7,056 for employees covered by Pillar 2 (occupational pension), and CHF 35,280 (up to 20% of net earned income) for self-employed persons without Pillar 2.

Money in a 3a account grows tax-free — no wealth tax on the balance, no income tax on interest or returns while it accumulates. You cannot access it freely; withdrawals are permitted only on retirement (from age 60), when leaving Switzerland permanently, buying a primary residence, starting self-employment, or in cases of disability.

At withdrawal, the lump sum is taxed at a reduced rate (separate from income, typically 5-10% depending on canton and amount). Contributing early and consistently is worthwhile given the compounding tax savings. You can hold multiple 3a accounts and stagger withdrawals across different years to minimize the tax hit at retirement.
