Can your pillar 3a fund a pension-fund buy-in?

Two ways to fill the same gap

A pension-fund statement may show a buy-in opportunity, but it does not tell you which money to use. An eligible buy-in paid with freely available savings and a qualifying direct transfer of existing 3a capital are different transactions. Under the Federal Tax Administration’s Circular 18a, a qualifying direct transfer to a tax-exempt occupational pension institution does not trigger tax on the transferred sum at that point. The same amount does not create a fresh deduction. This is a move between pension arrangements, not a new payment from your pocket.

Test the size of the transfer

Assume a Swiss pension fund confirms an eligible CHF 18,000 buy-in gap in writing, and your 3a account holds CHF 30,000. A partial transfer can be considered because CHF 18,000 would fill the entire confirmed gap. A request to move only CHF 8,000 from the same account would leave CHF 10,000 of the gap open and does not meet that partial-transfer condition. This simplified example assumes the institutions accept the transaction and no other restriction applies. Get an updated calculation: a change in employment or another buy-in can change the available amount.

Compare what the money becomes

Ask the fund what the buy-in changes in the projected pension and capital options, and how it treats the amount in the event of death. Ask the 3a institution for the actual transferable amount and any effect on insurance guarantees or risk benefits. With an insurance policy, the transferable amount may differ from premiums paid or the projected maturity benefit. Also ask whether there is an outstanding home-ownership withdrawal. Circular 18a explicitly distinguishes repaying that withdrawal from a qualifying buy-in; tied pension money cannot be used under this route to fill the gap created by the advance.

Ask for comparable written illustrations

Give both providers the same date and ask them to separate guaranteed amounts from projections. Compare the pension fund’s potential capital or pension benefit with the remaining 3a balance after transfer, rather than comparing an annual pension with a lump sum as if they were equivalent. If you want cash flexibility before retirement, keep that requirement visible: neither route turns restricted retirement assets into a general emergency reserve.

Get both institutions to agree before moving funds

Request a written sequence: which form to sign, which institution sends the payment, when the transfer becomes effective, and what confirmation you will receive. The money must go directly from the 3a institution to the occupational pension institution for the treatment described above. Do not route it through your own bank account or assume that the reverse transfer is available. Near retirement, verify applicable timing limits, any policy maturity date and planned capital withdrawals before signing. Compare the result with leaving the money in 3a and making no buy-in. The useful decision is about pension benefits, liquidity and future options, not just a tax entry.
