When you are dreaming about passing the Indian Revenue Service exam, many of them aspire to three letters: IAS. But among the tens of thousands of them, there is a quieter, sharper posse that it looks like the mainstream hasn’t quite tuned into yet – the Indian Revenue Service could well be the best career choice in the entire civil services ecosystem.
What is the Indian Revenue Service?
When most people hear Indian Revenue Service they think of someone sitting with a bunch of papers behind a dusty desk, stamping tax returns. That couldn’t be further from the truth.
The Indian Revenue Service is, at bottom, a law enforcement and policy-making juggernaut. It is also the financial backbone of India — the body that raises the funds that pay for hospitals, highways, schools, and defence. The service was formed in its current style in 1953 and is divided into two significant arms, the IRS (Income Tax) and the IRS (Customs and Indirect Taxes).
Nearly 9,775 officers, the two branches of the chargeable revenue service are testament to a cadre that pervades nearly every facet of the Indian economy.
Eligibility
- Applicants must be Indian citizens or belong to certain categories of Persons of Indian Origin (PIO) to apply for the IRS.
- The basic educational qualification is a Bachelor’s degree in any stream from any recognized university by the Government.
- UPSC is quite flexible in this regard as it permits the students pursuing the final year of University to appear in the Preliminary examination for the CSE examination on a provisional basis, however, they are required to submit the passing certificates before joining the Mains exam.
- The age limit is 21 — 30 years, you can check further below.

Work Responsibility
These are the people who appear and plunder the offices of billionaires at the break of dawn. They follow cryptocurrency tracks across borders. They capture drugs off the shore. They bust shell companies that hide thousands of crores in black money. And yes, they also sit in hearings, argue byzantine tax law before tribunals and help shape the very policies that dictate how India earns its revenue.
This is not a desk job. This is one of the most intellectually challenging, operationally thrilling and financially rewarding career in Indian public service.
Participate & Crack IRS
Hacking the Indian Revenue Service is tough but then, nothing good ever is. The only avenue of entry is through the UPSC Civil Services Examination, which is attempted by about 1.1 million aspirants every year. The exam takes place in three stages, all tough.
- The first is the Preliminary exams – a two-paper objective test to weed out the unprepared.
- Then there is Mains, nine descriptive papers penned down over a period of a few days, examining one on history and geography, ethics and economics, and so on.
- A final interview by a panel of seasoned bureaucrats and scholars.
| Mains Examination Paper | Subject Focus and Syllabus Parameters | Maximum Marks |
| Paper I (Essay) | Multiple topics requiring analytical and philosophical discourse. | 250 |

| Paper VII (Optional II) | Second paper of the chosen Optional Subject. | 250 |
Top Recommendations for Exam Preparation
The whole process, beginning to end, can take years of preparation. Most of the toppers are second-time IAS aspirants and they spend 2-4 years mugging up the NCERT textbooks, M Laxmikanth Indian Polity, Ramesh Singh Indian Economy and reading daily newspapers like The Hindu. They write answers daily in practice. Join offline coachings or attend world-class online platforms such as Vision IAS or Vajiram & Ravi from wherever they live.
Cutoff Marks Needed for Selection
A candidate from general category is usually required to rank between 239-379 to get IRS (Income Tax). For IRS (Customs and Indirect Taxes), the range is a little wider — something like 265 to 497. They are excellent ranks, well within the top 0.5% of all candidates. But unlike the IAS cut-off which is near impossible, the IRS is a realistic and achievable target for those who seriously prepare.
| Service | General Category (Last Rank) | OBC Category (Last Rank) | SC Category (Last Rank) | ST Category (Last Rank) |
| IAS (2024 Trends) | 78 —- 96 | 435 —- 457 | 567—- 629 | 528 —- 625 |
| IPS (2024 Trends) | 225 — 252 | 480 —-656 | 638 — 865 | 645 — 867 |
| IRS (Income Tax) | 239 — 379 | 485 — 706 | 602 — 969 | 674 — 1032 |
| IRS (Customs & IT) | 265 —- 497 | 515 — 823 | 649 — 970 | 680 —- 1053 |
The “big three” services—consisting of the Indian Administrative Service (IAS), the Indian Foreign Service (IFS) and the Indian Police Service (IPS)—are in the topmost Tier 1 class. These services traditionally take the bulk of the top 150 candidates. The IAS is the undisputed king of the civil services, with unparalleled executive powers, while the IFS has the glamour of global diplomatic representation, and the IPS has the unmatched power of the uniform.
The Indian Revenue Service holds the very prestigious Tier 2 bracket and is known for its unbeatable power in financial affairs along with a good urban living. With a bigger cadre size and distinct preference pattern giving priority to metro stability rather than rural administration, the IRS (IT) and IRS (C&IT) take a large chunk of the successful candidates which are ranked between 240 and 650 in the general category.
What Happens After the IRS Exam?
IRS (Income Tax) officers are on their way to Nagpur’s National Academy of Direct Taxes (NADT) — a sprawling green-fitted campus, where a 16-month professional course converts the generalist officers into financial experts. The content is demanding: income tax law, corporate accounting, forensic investigation, international taxation, transfer pricing. It’s not just classroom theory, either. Officers labor months in the trenches, conducting real assessments and audits with seasoned veterans.
IRS (Customs and Indirect Taxes) officers are trained at the brand new NACIN campus in Palasamudram, Andhra Pradesh — a breathtaking 500-acre establishment which also serves as a World Customs Organization regional training centre for the Asia-Pacific region. The syllabus here includes GST, customs law, border management, narcotics control and contemporary areas such as data analytics and artificial intelligence.
Holistic development is taken seriously in both academies. Morning physical training, evening cultural programmes and personal hobbies. The objective is to produce officers who are not just technically competent but mentally tough, well rounded human beings who can manage in high-pressure environments without losing their cool.

Pay Scale and Future Opportunities
The pay of IRS officers is very good and is governed by the 7th central pay commission (CPC). Financial estimates for the 8th CPC, as the pay commission is next in line, indicate a possible 2.25 multiplier to the basic pay, which would again make being in the service financially attractive. Officers join the service at Pay Level 10 ( Junior Time Scale ) and can rise in 30 years of service through the ranks to the Apex Scale at Pay Level 17.
The following outlines the elaborate and comprehensive financial and hierarchical system:
| IRS Designation | Pay Level | Basic Pay (7th CPC) | Estimated Gross Monthly Salary | Career Timeline (Approx.) |
| Assistant Commissioner | Level 10 | Rs 56100 | Rs 85000 | 0 – 4 Years |
| Deputy Commissioner | Level 11 | Rs 67700 | Rs 100,000 | 5 – 8 Years |
| Joint Commissioner | Level 12 | Rs 78800 | Rs 1,25,000 | 9 – 12 Years |
| Additional Commissioner | Level 13 | Rs 118500 | Rs 1,60,000 | 13 – 16 Years |
| Commissioner | Level 14 | Rs 1,44,200 | Rs 2,00,000 | 17 – 20 Years |
| Principal Commissioner | Level 15 | Rs 1,82,200 | Rs 2,40,000 | 20+ Years |
| Chief Commissioner | Level 16 | Rs 2,05,400 | Rs 2,80,000 | 25+ Years |
| Principal Chief Commissioner | Level 17 (Apex) | Rs 2,25,000 | Rs 3,20,000 | Apex Career Stage |
In cases where government accommodation is either not available or refused within the government-officer circle, the officers are paid a handsome House Rent Allowance (HRA) of 8% to 24% of their basic pay based on the tier categorization of the city in which they are posted.
Conclusion
Indian Revenue Service is not just a career option but a vocation for those who want to make a real difference and are willing to work in the shadows and not in the spotlight. It is a combination of power and responsibility, brain and brawn, permanence and challenge. IRS officers at the national and state level are, quite literally, the core of India’s power but theirs is an unobtrusive, unshowy, and often unacknowledged influence.
In a culture where the IAS, IPS and IFS reign supreme in public imagination, the IRS gets overlooked not because it does not hold enough power or prestige or purpose but because it doesn’t shout about it. And yet, for those with the time to can see its nuances, it provides one of the most rounded existences in Indian public service — professional esteem, financial security, urban postings, intellectual stimulation, and tangible national outcomes.
