Wait — what's actually happening?
Swiss tax law has half a dozen legal optimisation levers — annual Pillar 3a, LPP buy-ins, staggered lump-sum withdrawals, commune choice, mortgage and equity-comp timing. Each saves a different amount depending on your situation. Most calculators only do one. We compute all six against your specific profile and rank them by what they're worth for you.
