Swiss AHV and Pillar 2 Abroad 2026: Worldwide Payment, Lump-Sum Withdrawal and Withholding

The three-pillar system and what changes when you emigrate

Switzerland’s pension system has three pillars: the state pension AHV/IV (Alters- und Hinterlassenenversicherung / Invalidenversicherung) — Pillar 1; the occupational pension BVG (Berufliche Vorsorge, also called 2. Säule or LPP) — Pillar 2; and private pensions Pillar 3a (tax-privileged) and 3b. Each pillar has different rules on emigration and they often conflict, which is why so many emigrants make costly errors.

AHV (Pillar 1): keep it active wherever you live

AHV contributions stop when you leave Switzerland and the contract with a Swiss employer ends. Future contributions are not required — but contributing voluntarily can fill gaps. Your accumulated AHV credits are preserved for life and pay out from age 65 (or 64 for women born before 1965, transitioning under AHV 21 reform) regardless of where you live.

For non-EU residents (USA, Canada, UK, Australia, etc.), the optional AHV/IV continuation insurance allows you to continue contributing if you are a Swiss citizen registered with a Swiss embassy as Auslandschweizer. Annual contribution: 9.4-9.8% of foreign income (minimum CHF 980/year, maximum CHF 24’500/year for 2026). Apply within 1 year of departure via the Swiss Compensation Office (SAK / CSC, ahv-iv.ch).

For EU/EFTA residents, the EU coordination regulation 883/2004 applies — your AHV credits are aggregated with the new country’s pension system. You contribute to the new country’s pension scheme, not to Swiss AHV.

Pillar 2 (BVG): mandatory vs supplementary — the critical distinction

BVG funds are split into two regulatory categories with very different exit rules:

Mandatory portion (Obligatorium / Coordinated salary): covers salary up to CHF 88’200 in 2026 minus the AHV coordination amount (CHF 25’725). Mandatory BVG capital CANNOT be cashed out as a lump sum if you move to an EU/EFTA country and remain insured for old-age, disability and survivors’ benefits in that country. Instead, the capital is transferred to a Freizügigkeitskonto (vested benefits account) in Switzerland and paid out at retirement age (60-70).

Supplementary portion (Überobligatorium / Surobligatoire): covers salary above CHF 88’200 and any voluntary buy-ins (Einkäufe). This portion CAN always be cashed out as a lump sum on emigration, regardless of destination. Source tax applies at the rate of the foundation’s canton of registration.

For non-EU/EFTA destinations (USA, Canada, UK, Australia, Asia), BOTH portions can be cashed out as lump sum.

Splitting your BVG account before emigration

Many BVG funds report only the total balance — but the underlying split between mandatory and supplementary is documented in the annual statement (Vorsorgeausweis). Request a written breakdown from your fund 6-12 months before departure. If your fund commingles the two portions in a single account, ask for a formal split (Aufteilung) — this is your right under Article 25f BVG.

Once split, you can transfer each portion separately. Common strategy for EU emigrants: transfer the mandatory portion to a Freizügigkeitsstiftung in your home canton, and the supplementary portion to a low-tax canton (Schwyz, Zug, Nidwalden) for immediate lump-sum withdrawal at favourable source tax — see our tax exit guide.

Pillar 3a on emigration

Pillar 3a can always be withdrawn early on emigration regardless of destination. The withdrawal is taxed as a lump sum at source tax rates of the bank/foundation’s canton (3-10% depending on amount and canton). To optimise: transfer to Schwyz or Zug at least 12 months before withdrawal — this is widely used and fully legal.

Alternative: leave the Pillar 3a in place and withdraw at age 60-65. No further contributions can be made (since these require Swiss-taxable income), but the existing capital continues to compound at the bank’s interest rate.

Source tax optimisation: cantonal arbitrage explained

The savings on a CHF 500’000 lump sum can exceed CHF 25’000 — entirely legal under Swiss tax law and federal court precedent (BGE 130 II 65). Plan the transfer at least 12 months before withdrawal to avoid simulated-domicile challenges by tax authorities.

DTT refund: the second chance for source tax recovery

Some destinations allow a refund of Swiss source tax via the relevant double taxation treaty: Israel (full refund), UAE (full refund), Singapore (full refund), Thailand (full refund) and a few others. For these, file Form 96 with the Eidgenössische Steuerverwaltung (ESTV) within 3 years of withdrawal, accompanied by a residence certificate from the new country. The refund typically lands within 6-12 months.

For USA, Canada, UK, Germany, France, Italy, Spain, Netherlands, Belgium, Austria — Switzerland retains taxing rights and there is no refund. The new country may credit the Swiss tax against any local tax on the lump sum.
