FIRS Salary Ranks and Allowances

FIRS Salary Ranks and Allowances.

If you are considering a career with the Federal Inland Revenue Service (FIRS), one of the important things to understand is how salaries, ranks, grade levels and allowances work. FIRS is one of Nigeria’s major revenue-generating agencies and offers career opportunities for graduates, professionals and other qualified applicants.

However, there is often confusion online about the exact amount FIRS employees earn. Different websites publish different figures, while FIRS does not always publicly release a simple salary table showing the monthly earnings of every position. Therefore, salary information should be treated carefully, particularly when figures are described as “official.”

The Federal Inland Revenue Service is responsible for assessing, collecting and accounting for tax and other revenues accruing to the Federal Government. Because of the technical nature of its work, employees can occupy different professional, administrative, technical and management positions.

FIRS Salary Ranks and Allowances

FIRS does not necessarily follow the same salary arrangement as every other federal government ministry or agency. The National Salaries, Incomes and Wages Commission (NSIWC) has historically been involved in the approval and review of salary structures for FIRS and other government agencies. NSIWC records specifically mention the Federal Inland Revenue Service among organisations whose remuneration packages were reviewed. (NSIWC)

This means that the salary of a FIRS employee can depend on factors such as position, grade, qualification, experience, level of responsibility and the applicable remuneration structure.

Some salary figures published online for FIRS in 2026 place entry-level positions around ₦180,000 to ₦220,000 per month, with higher professional and management positions earning substantially more. These figures are estimates rather than a publicly confirmed FIRS salary table and should not be interpreted as guaranteed take-home pay. (Konnect NG)

FIRS Salary Ranks and Positions

FIRS has different job categories and levels rather than a conventional paramilitary-style rank system. The exact title attached to a position can vary according to the department and career cadre.

Some commonly referenced positions include:

• Tax Assistant or entry-level officer
• Tax Officer II
• Tax Officer I
• Senior Tax Officer
• Principal Officer
• Assistant Chief Officer
• Chief Officer
• Assistant Director
• Director

The higher the position and level of responsibility, the greater the expected remuneration.

An entry-level employee will generally earn less than an experienced officer who has progressed through several stages of the organisation. Promotion, additional responsibilities, professional qualifications and years of service can influence career progression and remuneration.

For example, published estimates for 2026 put some entry-level FIRS positions around ₦180,000–₦220,000 monthly, while estimates for senior positions can reach ₦600,000 or more per month, with top management positions potentially earning considerably higher amounts. Again, these figures should be viewed as estimates because individual compensation can differ. (Konnect NG)

FIRS Salary by Grade Level

Grade levels are important when discussing government employment because they help determine an employee’s position within a salary structure.

Some published FIRS salary estimates for 2026 give the following approximate ranges:

Grade Level 7: ₦180,000–₦220,000 monthly

Grade Level 8: ₦210,000–₦250,000 monthly

Grade Level 9: ₦250,000–₦300,000 monthly

Grade Level 10: ₦300,000–₦350,000 monthly

Grade Level 12: ₦350,000–₦400,000 monthly

Grade Level 13: ₦400,000–₦450,000 monthly

Grade Level 14: ₦450,000–₦500,000 monthly

Grade Level 15: ₦500,000–₦600,000 monthly

Grade Level 16: ₦600,000–₦750,000 monthly

Grade Level 17: ₦750,000–₦1,000,000 or more monthly. (Konnect NG)

These amounts should not be confused with confirmed take-home salaries. Basic pay, allowances, deductions, pension contributions and taxes can all affect the amount an employee eventually receives.

FIRS Allowances

Salary is only one part of an employee’s overall remuneration. Depending on the employee’s position, duties and eligibility, FIRS workers may receive various allowances and employment-related benefits.

Possible allowances and benefits can include housing or rent-related allowances, transport allowances, leave allowance, duty-related allowances, medical benefits, official travel allowances and other approved benefits.

The exact amount is not necessarily the same for every employee. An officer who travels for official assignments, for example, may receive an applicable duty or travel allowance that another employee who remains in the office may not receive.

Similarly, employees occupying senior positions may have access to benefits associated with their responsibilities that are not available to junior employees.

It is therefore misleading to take an allowance published for one position and assume that every FIRS employee receives the same amount.

The federal government also maintains official circulars covering different salary structures and allowances. NSIWC currently publishes circulars concerning salary structures, allowances, the Public Service Rules and remuneration adjustments. (NSIWC)

Does FIRS Pay Housing and Transport Allowance?

Housing and transport-related benefits can form part of government employee remuneration, depending on the applicable conditions of service and the employee’s entitlement.

However, there is no reliable basis for claiming that every FIRS employee receives one fixed amount for housing or transport. The entitlement can depend on the employee’s grade, position, location, applicable policy and other conditions.

This is important because some websites publish exact figures for FIRS allowances without providing an official circular or FIRS document supporting those numbers.

Anyone applying for a FIRS position should therefore avoid making financial decisions based solely on an online salary estimate.

FIRS Take-Home Salary

Your take-home salary is not necessarily the same as your gross salary.

For example, an employee may have a stated salary before deductions, while pension contributions, PAYE tax and other authorised deductions reduce the amount eventually paid into the employee’s bank account.

Allowances can also increase total earnings where the employee qualifies for them.

This is why two employees working within the same organisation can receive different amounts even when they have similar job titles.

What Determines FIRS Salary?

Several factors can influence how much a FIRS employee earns. These include:

Position: Senior positions generally attract higher remuneration.

Grade level and step: Employees at different levels and steps can receive different salaries.

Qualifications: Academic and professional qualifications can affect recruitment placement and career progression.

Experience: Years of relevant experience can influence placement and advancement.

Responsibilities: Employees with greater managerial or technical responsibilities may receive higher remuneration.

Allowances: Eligible allowances can increase total earnings.

Government salary reviews: Changes to federal remuneration policies can affect applicable salaries and allowances.

Final Thoughts

FIRS remains an important career destination for Nigerians interested in taxation, accounting, economics, law, finance, administration, information technology and other professional fields.

When considering FIRS employment, salary should not be the only factor. Job security, career progression, professional development, pension benefits, working conditions and opportunities for advancement are also important.

Most importantly, applicants should be careful with websites claiming to provide an “official FIRS salary structure” without identifying the government circular or document supporting their figures.

The FIRS salary ranks and allowances can change as government remuneration policies are reviewed. The most reliable approach is to confirm the salary and benefits attached to a particular position from the relevant FIRS recruitment information, employment documentation or applicable government remuneration circular.

The NSIWC maintains an official repository of salary structures and remuneration circulars, including materials relating to federal public-sector salaries and allowances. (NSIWC)

For anyone planning to apply for FIRS recruitment, understanding the difference between basic salary, gross earnings, allowances and actual take-home pay is essential before making a career decision.
