Swiss-born locals plan pension with a 30–40-year horizon and zero cross-border exposure. Most expats have neither.
The Swiss pension system rewards depth and time. For expats, the architecture decisions hinge on three variables that don't appear in standard Swiss pension advice: how long you'll stay, where you'll go next, and which pension regime your destination respects.
A 5-year-in-Switzerland horizon changes the pillar 3a math entirely. Leaving for the UK is straightforward (treaty network); leaving for the USA hits FATCA mechanics that most Swiss advisors don't know. Settling permanently and buying property activates the home-purchase withdrawal lever (Art. 5(1)(a) BVV3). Each shape needs different architecture.
The arrival-age math makes the point concretely. AHV wants 44 contribution years; BVG wants employer-matched saving from age 25. Arrive at 30 and you reach ~35 AHV years (~80% of the full pension) with 5 years of missing BVG accumulation; arrive at 40 and the AHV gap alone is ~43%. The later the arrival, the more architectural weight 3a and the BVG buyback have to carry — bilateral social-security agreements can count home-country years toward the qualifying period, though not toward the Swiss benefit itself.
| Arrival age | AHV years to 65 | AHV gap | Typical strategy |
| 25 | ~40 | ~9% | 3a maximisation; modest buyback if applicable |
| 30 | ~35 | ~20% | 3a max + BVG buyback prioritisation |
| 35 | ~30 | ~32% | Aggressive BVG buyback + 3a max |
| 40 | ~25 | ~43% | Buyback as largest single lever; 3a + 3b combined |
| 45 | ~20 | ~55% | Architecture review essential; 3b alongside 3a + buyback |
Nicole's review is built around these variables — gap analysis runs against the realistic horizon, not the default Swiss-permanent-resident assumption.
