Foreign pensions and your Swiss tax return

Do foreign pensions have to be declared?

You may have left an employer abroad years ago and kept the pension. When your Swiss tax return arrives, it is natural to wonder whether that balance belongs next to your bank accounts.

The answer depends on the pension plan and whether benefits have become payable. A recognised foreign pension may qualify for different treatment from ordinary savings. Its name alone does not tell you how to complete the return.

Keep three things separate: the pension rights you still hold, contributions you made and payments you received. They raise different tax questions.

What makes a foreign plan different from savings?

Swiss authorities look at whether a foreign arrangement is comparable with recognised Swiss retirement provision, such as occupational pensions or restricted pillar 3a savings. The assessment considers the scheme as a whole, including its legal framework, tax treatment and restrictions on access to the money.

Where the pension rights qualify, they can be excluded from taxable wealth before benefits fall due. That is different from saying you should withhold the plan details from your preparer or tax authority. Provide the information needed to establish the treatment and follow any disclosure instructions.

Canton Bern’s guidance on international pensions explains the individual comparability assessment (German).

What about a 401(k), IRA, RRSP or UK pension?

Start with the exact plan, not an online list of “taxable” and “tax-free” accounts. A broad label can hide details that matter: the type of arrangement, where earlier funds came from, the access rules and whether a payment has already been made.

If you have a 401(k), traditional or Roth IRA, Canadian RRSP, Australian superannuation account or UK pension, gather the current statement and scheme rules. Explain any transfer, rollover or withdrawal. Those documents give the person preparing your return something concrete to assess.

Where the position is unclear, ask the competent cantonal tax authority to confirm it. A decision about one person’s plan is not automatically an answer for another account with a similar name.

The Federal Tax Administration’s questions and answers directs individual pension-tax questions to the relevant canton.

Payments need a separate check

A pension balance receiving favourable treatment does not mean that future payments are automatically tax-free.

Regular pension income and a one-off capital payment can be treated differently. The country involved, the type of pension and the relevant tax treaty matter. State pensions, pensions linked to government service and private employment pensions should not be assumed to follow identical rules.

Keep the gross payment statement and details of foreign tax deducted. A net amount arriving in your bank account does not show the whole transaction. Before a withdrawal or transfer, check the consequences in both countries; the tax treatment of a lump sum cannot be inferred from the account balance alone.

See Solothurn’s guidance on foreign pensions (German) and the Federal Tax Administration’s country and treaty information.

A UK ISA is a separate question

Do not assume that an account described as tax-free in another country is also tax-free in Switzerland. An ISA is not automatically equivalent to a recognised pension just because you intend to use it in retirement.

UK guidance allows an ISA to retain UK tax relief after a move abroad in the circumstances it describes. That establishes the UK position, not a Swiss exemption. Include the account in the information you provide for your Swiss return and check the treatment of its assets and income.

Read GOV.UK’s guidance on ISAs after moving abroad. For ordinary accounts and investments, see our foreign income and assets guide.

Documents worth having ready

You do not need to guess the classification before asking for help. Start with a clear description of what you have:

• The country, provider, exact scheme name and latest annual statement.
• The plan rules, especially when and how benefits become payable.
• Details of employer and personal contributions, where available.
• Statements for withdrawals, regular payments, transfers or rollovers.
• Records of any foreign tax withheld.
• Earlier correspondence from a Swiss tax authority about the plan.

If a statement uses unfamiliar terminology, keep the original wording rather than relabelling the account as a Swiss pillar 2 or pillar 3a account yourself.

Before submitting your Swiss return

Tell your preparer about the pension even if you believe its balance is exempt. Mention anything that changed during the year. An account that was simply sitting in the background last year may need a fresh look after a withdrawal or a change in access rights.

This guide concerns the Swiss return. If you also have filing obligations abroad, those need their own review. We do not prepare US tax returns.
