An OASI pension is not determined by one “after how many years” rule: contribution periods, recorded income and the individual situation work together. Check the individual account and possible contribution gaps early. For Hungarian or other EU/EFTA periods, international coordination must be clarified with the responsible authority using your own record.

An OASI pension is not determined by one “after how many years” rule: contribution periods, recorded income and the individual situation work together. Check the individual account and possible contribution gaps early. For Hungarian or other EU/EFTA periods, international coordination must be clarified with the responsible authority using your own record.

Quick facts

Primary source: the OASI/DI information centre. A personal record is required for a concrete amount.

  • Contribution period and income both matter.

  • The individual account helps identify gaps.

  • International periods require an individual authority check.

Practical process

1. Check the individual account. 2. Raise gaps with the responsible fund. 3. Check the application route early. 4. Clarify international periods personally.

Scope

This is not a pension calculation or a cross-border entitlement decision.
