Swiss retirement planning picked up two new moving parts in 2026. December brings the first 13th AHV payment, one extra month of exactly your current pension, capped by the same Scale 44 and Plafonierung rules as every other month. And since 1 January, pillar 3a gaps from 2025 onward can be bought back retroactively, up to CHF 7,258 per year on top of the standard maximum, doubling the deduction in a catch-up year, provided the current year is maxed first.
