The payment limit is also a contribution limit
The Swiss Federal Tax Administration treats the annual ceiling as a limit on contributions, not merely on what you can claim on the return. Paying more and simply omitting the difference from the deduction does not resolve an excess. Check the ceiling for the year and the person’s actual occupational-pension affiliation. For 2026, the ordinary maximum with a second pillar is CHF 7,258. Without it, the limit depends on qualifying earned income, so the published absolute ceiling is not necessarily the amount you could pay. Do not use a bank’s generic annual target as confirmation of individual eligibility.
Reconcile actual credits rather than orders
Suppose a person affiliated throughout 2026 paid CHF 5,000 into a bank 3a and CHF 2,600 in ordinary contributions to a 3a policy, all credited that year. With no other contribution and no formal catch-up purchase, the total is CHF 7,600: CHF 342 above the ordinary limit. If a transfer between two 3a institutions appears in the account history, identify it separately rather than adding it as a new contribution. If one credit fell in January, check the certificate year. The example determines a possible excess, not a tax bill or an amount you can recover from either contract.
Ask for the correction process in writing
Gather all certificates, credited dates and amounts and ask the competent tax authority how it wants the correction handled. Circular 18a describes the authority instructing the taxpayer to obtain reimbursement from the pension institution. The reimbursement is for the nominal excess, without accrued interest. The circular distinguishes an insurance policy’s savings component from a risk premium for protection already provided; that premium cannot simply be refunded in the same way. This makes it particularly important to involve the insurer before changing a policy that contains both saving and protection.
Check the document before calling it an excess
The same bank statement can contain a transfer, a contribution and investment income. Compare the transaction labels with the provider’s tax certificate, and ask for a breakdown if one entry is unclear. If your affiliation changed during the year, show the dates alongside the credits. Do not assume the excess belongs to the institution that received the last payment; ask which institution should make the correction and retain proof of the answer.
Do not reclassify or carry forward the difference yourself
A catch-up purchase for a qualifying earlier gap follows its own process. It does not automatically absorb an ordinary overpayment. Similarly, do not deduct the difference from next year’s contribution without confirming how the provider and authority have treated the excess. Keep the instruction, the institution’s confirmation and any corrected attestation together. If the tax return is already filed, ask how to communicate the correction. When setting next year’s standing orders, reserve space for scheduled insurance premiums before deciding the amount of a final bank transfer. That small reconciliation prevents most duplicate top-ups.
