TNPSC Group 1 Officer (Tamil Nadu)

Running parts of the state government. A Deputy Collector handles revenue, land and law-and-order work in a district. A DSP leads police work. Commercial tax, registration, co-operative and labour officers run their departments. Group 1 posts change from year to year, so check each notification.

A day in the work
A Deputy Collector might start by meeting people with land, certificate or pension problems and signing orders. Then comes a field visit to check a flood-relief camp, a ration shop or a land dispute. Afternoons go to review meetings with tahsildars and other officers, and to files and reports for the Collector. In a crisis, such as a cyclone or an election, the day can run very late.

• The number of vacancies changes a lot. The 2024 notification had 90 posts (reported by DT Next). The 2025 notification had 28 Deputy Collector posts. The 2026 notification was reported to start at 26 posts, and some reports say it grew to 46. Check tnpsc.gov.in for the final count.
• The list of posts changes each year. DSP posts were in 2024 and 2025, but the 2026 list was reported to cover Deputy Collector, Commercial Taxes, Co-operative, Registration and Labour only.
• This is a state service, not the IAS or IPS. State officers may later be inducted into the IAS by selection after many years, but seats are limited. If you want the all-India route, look at the UPSC civil services.
• Never pay anyone for a 'seat' or 'sure selection'. TNPSC only uses its own website and the One Time Registration. Always check the official notification.
