In which category does the income tax inspector post falls in UPSC? Can I prepare for it on my own?

The candidates can cover the IAS prelims syllabus if in six months if they are appearing for it for the first time. In case, the candidate has cleared the prelims earlier, he or she can prepare it in three months.

The Union Public Service Commission will notify the UPSC IAS Syllabus 2026 in its official notification. The Commission will release the Civil Service 2026 notification on January 14, 2026.

The UPSC IAS Prelims and Main exam syllabus is different. The candidates can say that the Prelims syllabus is a subset of the main because it is very vast and extesive.

In my opinion, if you want to prepare for UPSC or any other competitive exams later, you can pursue a BA in Political Science, Economics, History, or Sociology. Since their syllabus is heavily equipped with GK, Indian and world history, public policy, public administration, Indian and world politics, it'll be easier for you to strengthen your base.
