Pillar 3a
In one sentence
Tied retirement savings: deductible from taxable income, locked until retirement with exceptions.
What it changes for you
The annual deductible ceiling is set each year by the Confederation and differs depending on whether you belong to a pension fund. Three early withdrawals are allowed: buying your main home, leaving Switzerland for good, becoming self-employed. The final payout is taxed separately at a reduced rate — hence the value of holding several accounts and withdrawing them in different years.
