Three items on different records
Paying Swiss OASI contributions as a non-employed person can help prevent contribution gaps in the first pillar. A care credit may also enter the OASI pension calculation if conditions are met. Neither those contributions nor the credit is itself a wage subject to OASI. Eligibility for 3a requires examining earned income or qualifying replacement income, not simply whether an OASI record exists.
Two years that look similar in a household budget
Suppose someone leaves a job to care for a parent. They earned OASI-covered wages from January through March 2026. Assume that in 2027 they have neither earned income nor qualifying replacement income. They should not treat those years the same, even if they pay personal OASI contributions in both. For the year with wages, they check how cessation affects the ceiling and timing. In the year without eligible income, non-employed OASI contributions are not sufficient.
Verify what kind of income you receive
Replacement income may be treated differently according to its nature and the social contributions withheld. Request the certificate and, where needed, confirmation from the compensation office or tax authority. Help from a family member or a household payment does not establish recognised wages. If part-time work resumes, keep the dates, payslips and confirmation of any occupational pension membership.
Plan for returning to work without assuming a buy-in
Review standing orders and insurance premiums before changing them. An insurance-based 3a may have separate contractual consequences when premiums are reduced or stopped. A year without contribution eligibility does not become eligible for a later buy-in just because you return to work. During the break, compare an accessible reserve and other saving options, then revisit 3a when you have new evidence.
Make a month-by-month record
On a single page, record when your old employment ended, when any new work began and which months had no earnings. Add your salary certificate, any benefit decisions and your individual OASI account statement. If you left a job midway through the year, an annual certificate may still show employment income despite several months without pay. Check that year separately from the following year if you spent the whole of it providing unpaid care.
Take two separate questions to the compensation office
Ask how it records the months in which you were out of work, then ask how to claim any care credit you may qualify for. For 3a, ask your pension provider what the actual income types on your timeline mean for eligibility in each calendar year. A document that settles one question may not settle the other, even when both refer to OASI.
