Developments: 4. Legal and administrative developments regarding social security (SGK) premium records in Turkey have highlighted issues surrounding service day validity. A ruling by the Turkish Court of Cassation established a precedent for employees working remotely during the pandemic, ordering the registration of missing service days for an academic whose digital records proved continuous employment despite incomplete SGK entries. The Court of Cassation’s 10th Civil Chamber recently affirmed a decision requiring the addition of 189 missing service days for an academic who worked via online lessons between December 2020 and June 2021, setting a precedent for pandemic-era remote work arrangements. Concurrently, experts have warned that discrepancies in service records can lead to the cancellation of retirement applications or the termination of pension payments. Specific indicators in service records, such as the ‘K’ code for workplaces under inspection, the ‘Ş’ code for suspicious notifications, and the ‘S’ code for fraudulent records, may trigger audits. If invalid days are removed, workers may fall below retirement thresholds, resulting in demands for the repayment of pensions and healthcare expenses. Experts also note that overlapping premium periods, such as simultaneous 4/A and 4/B notifications, do not increase total day counts. To combat informal employment, the SGK has introduced new regulations allowing official reports from law enforcement, municipal police, doctors, and other public officials to serve as direct evidence of working days. Under a new circular, the SGK’s Unregistered Employment Combat (KADİM) services will manage this process. While initial guidelines suggested documented periods would be classified as part-time work, updated regulations specify that when non-inspection public officials—such as police, gendarmerie, doctors, or engineers—identify an uninsured worker, a fine equivalent to twice the minimum wage is applied per person and insurance registration is processed. ## Timeline ### 2026-10-27: Turkey's SGK updates regulations on unregistered employment detection Turkey's SGK has updated its rules for unregistered employment, limiting service day credits from non-inspection official reports to one day per record. 2 sources. https://clstr.news/cluster/turkeys-sgk-updates-regulations-on-unregistered-employment-detection ### 2026-10-24: Turkey's SGK introduces new rules to convert official records into insurance days Turkey's SGK will now use official reports from public officials and traffic fines as evidence to grant insurance premium days to workers previously engaged in unregistered employment. 10 sources. https://clstr.news/cluster/turkeys-sgk-implements-new-rules-to-convert-official-reports-into-social-security-days ### 2026-10-19: SGK expert warns of pension cancellations due to invalid premium days SGK expert Özgür Erdursun warns that invalid premium days marked by K, Ş, or S codes can lead to the cancellation of retirement benefits or demands for repayment of past pensions. 5 sources. https://clstr.news/cluster/sgk-expert-warns-of-pension-cancellations-due-to-invalid-premium-days ### 2026-10-03: Turkish Court of Cassation mandates registration of missing pandemic-era SGK premiums Turkey's Court of Cassation has upheld a ruling requiring the registration of 189 missing social security premium days for an academic who worked remotely during the pandemic. 4 sources. https://clstr.news/cluster/turkish-court-of-cassation-mandates-registration-of-missing-pandemic-era-sgk-premiums --- Cite as: Turkish social security premium disputes.
