In fact, there is a surprisingly generous rule on the number of pillar 3a accounts.
By law, the number of pillar 3a accounts or policies is not limited. A person may therefore hold as many as they wish. Only the annual maximum amount is capped, and it applies to all accounts together. But why would anyone want several accounts? The reason lies in the tax law on withdrawal. When the savings are eventually paid out, a capital withdrawal tax is due, and it is progressive: the larger the one-off withdrawal, the higher the tax rate. Anyone who spreads their savings across several accounts and withdraws them staggered over different years breaks this progression and may save several thousand francs.
It is a simple mechanism that can be put to use early with a little foresight. Anyone who spreads their pension provision across several accounts from the start creates room for manoeuvre in the years around retirement, when every franc saved in tax counts.
