If you are searching for FIRS staff salary per month in 2026, FIRS salary structure, or how much tax officers earn in Nigeria, you are not alone. Many graduates, job seekers and people interested in public-sector careers want to know what they could earn working for Nigeria’s federal tax authority.
There is, however, an important update to understand before looking at salary figures: FIRS has transitioned to the Nigeria Revenue Service (NRS) under the Nigeria Revenue Service (Establishment) Act, 2025. The new law repealed the former FIRS Establishment Act and established the NRS as the federal revenue authority.
This means that people still searching for terms such as “FIRS salary 2026” are generally looking for information about the organisation now operating as the Nigeria Revenue Service (NRS).
So, how much does a FIRS/NRS staff member earn per month in 2026? The short answer is that there is no single monthly salary for every officer. Pay depends on the position, grade, step, experience, applicable salary structure and allowances.
FIRS Salary per Month in 2026: What Should You Expect?
Various online salary guides publish estimates for FIRS/NRS employees, but these figures should not be treated as an official universal salary table.
For example, published estimates for entry and mid-level positions commonly place monthly earnings within broad ranges such as ₦180,000 to ₦350,000, while more senior positions may earn considerably more. Other published estimates give different figures, demonstrating why applicants should be cautious about treating an online salary figure as guaranteed take-home pay.
The reason for these differences is simple: an employee’s compensation is not necessarily the same thing as basic salary.
An employee may have:
- Basic salary
- Applicable allowances
- Pension deductions
- PAYE or other statutory deductions
- Approved duty-related payments
- Other authorised deductions or benefits
Therefore, FIRS salary per month and FIRS take-home salary per month are not necessarily the same amount.
Estimated FIRS/NRS Monthly Salary Ranges
The following ranges are best understood as published market estimates rather than official NRS salary quotations:
| Career level | Commonly published estimated monthly range |
|---|---|
| Entry-level/graduate officer | ₦160,000 – ₦250,000 |
| Tax Officer/Officer II | ₦210,000 – ₦300,000 |
| Officer I | ₦250,000 – ₦350,000 |
| Senior/Mid-level officer | ₦300,000 – ₦400,000+ |
| Principal/senior management roles | ₦350,000 – ₦700,000+ |
| Higher management roles | ₦600,000 – ₦1,000,000+ |
These figures vary substantially between published sources, and the actual remuneration of a particular employee can depend on the applicable employment terms and government remuneration arrangements.
For that reason, anyone applying for a position should avoid assuming that a figure found on a blog is the exact amount that will appear in their bank account.
How Much Does a Tax Officer Earn at FIRS/NRS?
The phrase “tax officer salary in Nigeria” can refer to several different positions and grades. A tax officer working at an entry level will not necessarily earn the same amount as an experienced officer or manager.
Some 2026 online estimates place a Tax Officer or Officer II around ₦210,000 to ₦250,000 per month, while other sources place tax officer salaries in a wider range of approximately ₦250,000 to ₦350,000, depending on the position and assumptions used.
This difference highlights an important point: job title alone is not enough to calculate an employee’s exact salary.
The grade level, step, employment terms and applicable allowances matter.
A person entering the organisation may therefore have a different package from someone who has been promoted several times.
Why FIRS Salary Figures Differ Online
If you have searched Google for “FIRS salary structure 2026,” you may have noticed that different websites provide completely different numbers.
This happens for several reasons.
1. Different sources use different definitions of salary
One website may be reporting basic salary, while another may include selected allowances.
A third source may be reporting an estimated total monthly package.
These are three different things.
2. Salary depends on grade and step
Government remuneration commonly uses grades and steps to determine where an employee falls within a salary structure.
Two employees working in the same organisation may therefore receive different amounts because they occupy different positions or have different grades and steps.
3. Allowances can change total compensation
Allowances may apply according to an employee’s role, duties, location or official assignment.
The National Salaries, Incomes and Wages Commission (NSIWC) maintains official information on federal salary structures and published a peculiar allowance for staff on the Consolidated Public Service Salary Structure effective from 1 May 2026.
This is one reason salary information needs to be checked against current government circulars rather than relying entirely on old blog posts.
4. Take-home pay is affected by deductions
Even if an employee’s gross monthly compensation is known, the amount eventually received can be lower after applicable deductions.
Depending on the employee’s circumstances, deductions may include pension contributions, PAYE and other authorised deductions.
Therefore, asking “How much does FIRS pay per month?” is slightly different from asking “How much does a FIRS employee take home?”
What Salary Structure Applies to Federal Government Employees?
The Nigerian government has several consolidated salary structures covering different categories of public-sector workers.
The Consolidated Public Service Salary Structure (CONPSS) is one of the structures published by NSIWC. The commission’s official salary-structure archive includes CONPSS materials as well as information concerning the implementation of the new national minimum wage in the federal public service.
However, it would be misleading to assume that every FIRS/NRS position can simply be assigned a particular CONPSS figure found online.
The Nigeria Revenue Service is a specialised revenue institution, and employee remuneration can depend on the applicable structure and approved arrangements for the Service.
This is why a salary table copied from another government agency should not automatically be presented as the official NRS salary scale.
FIRS/NRS Salary by Grade Level
Grade level is frequently mentioned when people search for FIRS salary by grade level.
Published online estimates have suggested figures along these lines:
| Grade level | Frequently published estimated monthly range |
|---|---|
| GL 7 | ₦180,000 – ₦220,000 |
| GL 8 | ₦210,000 – ₦250,000 |
| GL 9 | ₦250,000 – ₦300,000 |
| GL 10 | ₦300,000 – ₦350,000 |
| GL 12 | ₦350,000 – ₦400,000 |
| GL 13 | ₦400,000 – ₦450,000 |
| GL 14 | ₦450,000 – ₦500,000 |
| GL 15 | ₦500,000 – ₦600,000 |
| GL 16 | ₦600,000 – ₦750,000 |
| GL 17 | ₦750,000 – ₦1,000,000+ |
These numbers are not an official NRS salary table. They are examples of figures currently published by third-party salary websites and should be used only as general estimates.
For anyone making a career decision, the appointment letter, official recruitment information and applicable government remuneration circulars are more reliable than an online salary estimate.
What Allowances Can FIRS/NRS Staff Receive?
Salary is only one part of employment compensation.
Depending on the employee’s position and applicable rules, federal public-service compensation can include different allowances and benefits.
Possible components may include:
- Housing-related benefits or allowances
- Transport-related allowances
- Medical benefits
- Leave-related benefits
- Official duty or travel allowances
- Pension benefits
- Training and professional development
- Other job-specific allowances
Not every employee receives every allowance, and an allowance should not automatically be added to an advertised salary figure.
The NSIWC officially publishes information on salary structures and reviews of allowances, including the 2026 review of daily travelling allowance, estacode and other allowances for federal public-service officers on GL 01–17.
Does FIRS/NRS Pay More Than Ordinary Civil Service Jobs?
This is a question many prospective applicants ask.
It is difficult to make a blanket statement because federal government institutions can operate under different remuneration arrangements, and salaries depend on job category, grade, step and approved allowances.
More importantly, the salary of one employee should not be compared with the basic salary of another employee while ignoring allowances and deductions.
For example, an employee with a lower basic salary could have a different overall package because of role-specific allowances, while another employee may have a higher basic salary but different deductions.
For this reason, applicants should compare complete compensation packages rather than headline monthly figures alone.
What Does a FIRS/NRS Tax Officer Do?
A tax officer is involved in work connected with tax administration and revenue collection.
The Nigeria Revenue Service is responsible for federal revenue functions, including the assessment and collection of revenue accruable to the federal government. The NRS website lists tax services including individual income tax, company income tax, VAT, withholding tax and stamp duties.
Depending on the department and assignment, an officer may work on areas such as:
- Taxpayer services
- Tax compliance
- Tax assessment
- Tax audits
- Revenue administration
- Taxpayer registration
- Data analysis
- Investigation and enforcement
- Tax policy support
- Administrative functions
The exact responsibilities depend on the position and department.
Qualifications for FIRS/NRS Jobs
Qualification requirements depend on the vacancy.
A graduate recruitment position may require a relevant university degree or other recognised qualification, while specialist positions can require professional or technical credentials.
Applicants should always rely on the official recruitment notice for the specific position rather than assuming that every NRS vacancy has the same requirements.
The official NRS recruitment portal provides a staff-category process and applicant verification system.
This is particularly important because recruitment information is frequently copied across websites, and old FIRS information may remain online even after the transition to NRS.
Is FIRS Still Called FIRS in 2026?
Technically, the federal revenue authority has transitioned from FIRS to the Nigeria Revenue Service (NRS).
The Nigeria Revenue Service (Establishment) Act, 2025 established the NRS and repealed the Federal Inland Revenue Service (Establishment) Act, 2007.
However, people still commonly use the phrase “FIRS salary” because:
- FIRS was the former name of the organisation.
- Many older job and salary articles still use FIRS.
- Search engines continue to show historical FIRS-related pages.
- Job seekers may search using the terminology they have previously encountered.
Therefore, both FIRS salary 2026 and NRS salary 2026 may appear in searches, but current official information should be checked against NRS sources.
How to Verify the Latest FIRS/NRS Salary Information
Before accepting any salary figure published online, check several things.
First, confirm whether the information refers to FIRS or the current NRS.
Second, check whether the amount is:
- Basic salary
- Gross salary
- Total compensation
- Salary plus allowances
- Estimated take-home pay
Third, check the date of the information.
A salary article written several years ago may no longer reflect current government remuneration.
Finally, check official government sources. The NRS maintains its official website with information about the Service, tax laws, transparency resources and career-related information, while NSIWC publishes government salary structures and remuneration circulars.
