Then ZUS will write off these debts. There is a message and a date

ZUS will automatically cancel debts incurred before January 1, 1999, including social security contributions and related fees. Notifications will be sent to debtors after May 1, 2027, and they can opt out within 30 days. The cancellation also applies to enforcement proceedings and secured debts. If a debtor opts out, enforcement will continue. The cancellation may affect future pension calculations, as periods of canceled contributions will not count towards pension entitlements, but will count towards work experience under labor law.
