Indian Revenue Service

The Indian Revenue Service, or IRS, is a Group A organised Central Civil Service that administers India’s taxes under the Department of Revenue in the Ministry of Finance. It has two separate branches: IRS (Income Tax), which runs direct taxes under the Central Board of Direct Taxes , and IRS (Customs and Indirect Taxes), which runs GST and customs under the Central Board of Indirect Taxes and Customs. Officers enter as an Assistant Commissioner at Level 10 of the pay matrix, with an entry basic of Rs. 56,100 a month.

This page sets out the service: its two branches, how it is entered through the UPSC examination and by promotion, the pay at entry and at each rank, the training academies, and the work. The exact in-hand at entry is worked out by the salary by pay level calculator , set here to Level 10.

The two services

The Indian Revenue Service is not one service but two, split by the kind of tax each administers, and the split runs all the way up each cadre.

IRS (Income Tax) administers the direct taxes, chiefly income tax under the Income-tax Act, 1961, and it is controlled by the Central Board of Direct Taxes . Its officers staff the Income Tax Department, from Assistant Commissioner up to the Principal Chief Commissioners and the Members of the Board. IRS (Customs and Indirect Taxes) administers the indirect taxes, now the Goods and Services Tax along with customs, central excise, and narcotics enforcement, and it is controlled by the Central Board of Indirect Taxes and Customs. The two boards both sit under the Department of Revenue, but the services are distinct: an officer belongs to one cadre for a whole career and does not cross between them.

Entry and recruitment

There are two ways into the Indian Revenue Service, and they meet at the Assistant Commissioner grade.

The main route is direct recruitment through the UPSC Civil Services Examination, the same examination that recruits the IAS and the IPS. A candidate is allotted the IRS on the basis of the rank and the service preference given, and joins as an Assistant Commissioner at Level 10. The second route is promotion from within: an officer of the Group B departmental cadre, an Income Tax Officer , is promoted into the Group A service as an Assistant Commissioner. At the entry grade the direct recruits and the promotees are drawn in a fixed ratio, so a part of every Assistant Commissioner batch has come up from the Income Tax Inspector grade rather than through the UPSC exam. The central government jobs hub sets out how the UPSC and SSC routes divide the recruitment.

Pay at entry and in-hand

An IRS officer starts at Level 10, the entry grade for directly recruited Group A officers across the civil services, with an entry basic of Rs. 56,100 a month.

The in-hand of about Rs. 1,01,000 is for an X-class city. Unlike the Level 7 and Level 8 posts below, income tax is no longer nil here: the annual taxable income crosses the Rs. 12 lakh rebate limit under the new regime, so a monthly tax of about Rs. 7,050 applies. The salary by pay level calculator recomputes the figure for a given city and scheme, and the income tax for government employees article works through the regimes at this income.

The rank and pay ladder

The Indian Revenue Service runs from Level 10 at entry to the apex Level 17, and the ranks track the pay matrix levels.

Level 17 is the apex scale, a single fixed figure of Rs. 2,25,000 with no increments, drawn by the Principal Chief Commissioners and the Members of the Board; the Chairman of the Central Board of Direct Taxes heads the Income Tax cadre at that scale. Very few officers reach the top, and the higher ranks come through selection and vacancy, not automatically.

Training

A new IRS officer trains before taking charge. After a common Foundation Course with the other civil services at the Lal Bahadur Shastri National Academy of Administration in Mussoorie, the officer moves to the branch academy: an IRS (Income Tax) officer to the National Academy of Direct Taxes in Nagpur, and an IRS (Customs and Indirect Taxes) officer to the National Academy of Customs, Indirect Taxes and Narcotics. The training runs to the specialised law and practice of the branch, so an Income Tax officer learns assessment, investigation, and the Income-tax Act in depth, while a Customs officer learns GST, customs valuation, and enforcement.

What IRS officers do

An IRS (Income Tax) officer runs the assessment and enforcement of direct taxes. At the Assistant and Deputy Commissioner grades the officer is an assessing officer for the higher-value and corporate cases that sit above the Income Tax Officer , and moves through postings in assessment, in the TDS and international-taxation wings, and in the investigation directorates that conduct search and survey. At the senior grades the work shifts to supervision, appeals, and policy, up to the Members of the Board who frame direct-tax policy. An IRS (Customs and Indirect Taxes) officer does the parallel work on the indirect side: GST administration, customs clearance and valuation, anti-smuggling enforcement, and adjudication.

From the departmental cadre

For a candidate who does not clear the UPSC examination, the Indian Revenue Service is still reachable, by the long route through the departmental cadre. The path starts with the Income Tax Inspector post, filled through the SSC Combined Graduate Level examination at Level 7, runs through promotion to Income Tax Officer at Level 8, and reaches the service when the Officer is promoted to Assistant Commissioner at Level 10. It depends on vacancies in the promotion quota and takes many years, but it is the reason a part of every Assistant Commissioner intake has come up from the Inspector grade. The salary by pay level chart shows the pay at each rung of that climb.

Pension

An IRS officer recruited after 1 January 2004 is covered by the National Pension System , contributing 10 per cent of basic plus dearness allowance against the government’s 14 per cent, or by the Unified Pension Scheme if opted from 1 April 2025, which assures 50 per cent of the average of the last 12 months’ basic pay after 25 years. The Old Pension Scheme is closed to post-2004 entrants, so no serving IRS officer today is on it.
