Pillar 3a in Killwangen: compare and contribute wisely

With pillar 3a you save twice over: contributions up to the maximum immediately lower your tax bill, and the balance grows long term for retirement. What matters in Killwangen is the size of the contribution and the choice of provider — between a safe 3a account, a return-oriented securities solution and a 3a insurance policy, the gap in cost and yield is wide.

Over 20 to 30 years, differences in fees and returns add up to five-figure amounts. So compare the type of solution (safe account vs. funds), the total costs and the flexibility (transfer, contribution rhythm). The effective tax saving depends on your marginal tax rate — that is, on your income, the canton of Aargau and your municipality. On withdrawal the capital is taxed separately at a reduced rate; several 3a accounts allow staggered withdrawals.

Hallmarks of a good 3a solution

Low total costs (management fee plus fund costs / TER).
Equity share suited to your investment horizon until retirement.
Flexible contributions and free transfer to another provider.
Withdrawal planning: several accounts for staggered, tax-efficient withdrawals.
