By Akash Sharma The Intelligence Bureau (IB) is India’s domestic counterintelligence and security service, functioning under the Ministry of Home Affairs. It is one of the oldest intelligence agencies in the world and occupies a unique position in India’s national security architecture. Recruitment into IB happens across two distinct entry levels — the Security Assistant (SA) at the ground level and the ACIO (Assistant Central Intelligence Officer) Grade II at the officer level. Both carry the distinctly higher Special Security Allowance that sets IB salaries apart from comparable government posts.
This article covers the complete IB Security Assistant and IB ACIO salary for 2026 — basic pay, all allowances including the critical Special Security Allowance, deductions, in-hand figures, and career progression for both posts.
IB Salary 2026: Two Distinct Entry Posts
| Post | Pay Level | Basic Pay | Who Recruits |
| Security Assistant (SA/Executive) | Level 3 | ₹21,700 – ₹69,100 | IB direct recruitment (10th pass) |
| ACIO Grade II / Executive | Level 7 | ₹44,900 – ₹1,42,400 | IB direct recruitment (graduate) |
These are two separate examinations, two separate recruitment processes, and two very different salary structures. Most searches combining “IB Security Assistant” and “ACIO” are looking for salary comparisons — both are covered in full below.
Part 1: IB Security Assistant (SA/Executive) Salary 2026
Quick Overview
| Component | Details |
| Pay Level | Level 3 (7th Pay Commission) |
| Basic Pay | ₹21,700 – ₹69,100 |
| Grade | General Central Service Group C, Non-Gazetted |
| Special Security Allowance | 20% of basic pay |
| Gross Monthly Salary | ₹34,130 – ₹38,000 |
| In-Hand Salary | ₹28,000 – ₹32,000 |
IB Security Assistant Pay Scale
Level 3: ₹21,700 – ₹69,100
Annual increment of 3 percent, identical to all central government Level 3 employees. However, the IB Security Assistant’s salary is meaningfully enhanced over equivalent Level 3 posts in other departments through the Special Security Allowance.
Salary Structure: All Components
| Component | Amount (Approx.) |
| Basic Pay | ₹21,700 |
| Dearness Allowance (50%) | ₹10,850 |
| Special Security Allowance (20% of basic) | ₹4,340 |
| HRA (27% — Metro/X-city) | ₹5,859 |
| Transport Allowance | ₹900 – ₹3,600 |
| Gross Monthly Salary | ₹34,130 – ₹38,000 |
| NPS + CGHS + CGEGIS | ₹2,400 – ₹2,600 |
| In-Hand Salary | ₹28,000 – ₹32,000 |
The Special Security Allowance (SSA) — What Makes IB Unique
The Single most important financial differentiator between IB posts and equivalent central government posts at the same pay level is the Special Security Allowance of 20 percent of basic pay.
For an IB Security Assistant at Level 3 basic pay of ₹21,700:
- SSA = 20% × ₹21,700 = ₹4,340 per month
- Annual SSA = ₹52,080
This is a non-taxable, guaranteed component paid to all Intelligence Bureau personnel — recognising the operational risk, secrecy obligations, and unconventional working conditions inherent to intelligence field work.
A comparable Level 3 CISF or BSF Constable does not receive SSA (they receive Risk and Hardship Allowance at some postings instead). The SSA makes the IB Security Assistant take-home genuinely higher than SSC GD constables at equivalent basic pay in normal postings.
Cash Compensation for Holiday Duty
IB Security Assistants receive additional cash compensation in lieu of duty performed on gazetted holidays — subject to a ceiling of 30 days per year. This adds an additional ₹12,000 to ₹25,000 annually depending on duty roster.
IB Security Assistant Job Profile
The Security Assistant works at the ground level of intelligence operations:
- Patrolling and security checks at IB premises and field positions
- Day and night shift security monitoring
- Escorting sensitive personnel and documents
- Supporting field intelligence operations under officer supervision
- Assisting ACIO and senior officers in data collection and surveillance support
The role requires physical fitness, discretion, and readiness for unconventional work hours. Postings are primarily in state capitals and major cities at IB district offices and field stations.
Career Progression: Security Assistant to Intelligence Officer
| Rank | Timeline |
| Security Assistant / Executive | At joining |
| Senior Security Assistant | 4–6 years + departmental exam |
| Junior Intelligence Officer (JIO) | 3–5 years as Senior SA + exam |
| Intelligence Officer (IO) | Further service + exam |
| Senior Intelligence Officer (SIO) | Further service |
| Assistant Director | Promotion from SIO |
Each promotion carries a shift to a higher pay level with correspondingly higher SSA, DA, and HRA components.
Part 2: IB ACIO Grade II / Executive Salary 2026
The ACIO (Assistant Central Intelligence Officer) Grade II / Executive post is the officer-level entry into IB — requiring a graduate degree and selected through the IB ACIO examination conducted by the Intelligence Bureau itself (not SSC).

IB ACIO vs GST Inspector vs Income Tax Inspector: Salary Comparison
All three posts are at Pay Level 7 with identical basic pay of ₹44,900. The difference:
| Feature | IB ACIO | GST Inspector | Income Tax Inspector |
| Basic Pay | ₹44,900 | ₹44,900 | ₹44,900 |
| Special Security Allowance | 20% = ₹8,980 | None | None |

| In-Hand Monthly (Metro) | ₹70,000 – ₹75,000 | ₹65,000 – ₹75,000 | ₹65,000 – ₹75,000 |
The Special Security Allowance of ₹8,980 per month makes IB ACIO the highest in-hand earner among all Level 7 SSC/central government posts. Over a full year, SSA alone adds ₹1,07,760 — a significant financial advantage.
