Key figures — Nigeria, 2025

Every figure is drawn from this Guide and cited to its source.

CRA formula

CRA = max(NGN 200,000, 1% x Gross Income) + 20% x Gross Income

R-NG-1

Non-resident earning Nigeria-source incomeStop — WHT as final tax (10% on professional services); different rules

R-NG-2

Residency unknownStop — different treatment

R-NG-3

State of residence unknownStop — determines filing authority

R-NG-4

Capital expenditure claimed as expenseReject — must use capital allowance schedule

R-NG-5

Old personal allowance / children's allowance systemStop — replaced by CRA from 2020

R-NG-6

Petroleum profits taxEscalate — separate regime

T1-NG-1 — CRA is computed on GROSS income, not net

The Consolidated Relief Allowance formula uses gross total income (before expenses), not assessable or taxable income. This is a common error. Always apply CRA to gross.T1-NG-1

T1-NG-2 — Minimum tax is a floor

Always compare computed tax per progressive rates with 1% of gross income. The taxpayer pays whichever is HIGHER. Minimum tax cannot be avoided by high expenses.T1-NG-2

T1-NG-3 — Capital expenditure must use capital allowances

Never deduct capital expenditure directly as a business expense. Use the Fifth Schedule rates (initial allowance in year of first use, annual allowance thereafter).T1-NG-3

T1-NG-4 — WHT is a credit, not income reduction

Withholding tax (10% on professional fees, 5% on contracts) deducted by clients is a credit against final tax. It does not reduce gross income. Must have WHT certificate to claim credit.T1-NG-4

T1-NG-5 — Filing authority depends on state of residence

FCT (Abuja) residents file with FIRS. All other states file with the State Internal Revenue Service (SIRS). This is not optional.T1-NG-5

T1-NG-6 — Old personal allowance system is abolished

The pre-2020 system of personal allowance + children's allowance + dependent relative allowance was replaced by CRA. Never apply the old deductions.T1-NG-6

Step 1 — Income

Annualised gross: NGN 8,000,000. WHT deducted by PJ clients: NGN 500,000.

Step 2 — Expenses

Accounting: NGN 150,000; travel: NGN 85,000; telecom: NGN 300,000; software: NGN 240,000; marketing: NGN 180,000; office rent: NGN 1,200,000; generator fuel: NGN 360,000; other: NGN 485,000. Total: NGN 3,000,000.

Step 3 — Computation

Gross income:             NGN  8,000,000
Less expenses:            NGN  3,000,000
Assessable income:        NGN  5,000,000
Add other income:         NGN          0
Gross total income:       NGN  8,000,000 (for CRA calculation)

CRA: max(200,000, 80,000) + 20% x 8,000,000 = 200,000 + 1,600,000 = NGN 1,800,000
Pension relief:           NGN    120,000

Taxable income: 8,000,000 - 3,000,000 - 1,800,000 - 120,000 = NGN 3,080,000

Tax:
  300,000 x 7%  =   21,000
  300,000 x 11% =   33,000
  500,000 x 15% =   75,000
  500,000 x 19% =   95,000
1,480,000 x 21% =  310,800
Total:              NGN 534,800

Minimum tax: 1% x 8,000,000 = NGN 80,000
Computed tax > minimum → pay NGN 534,800

Less WHT credit: NGN 500,000
Tax due: NGN 34,800

Example 2 — Access Bank (Abuja, Consultant — WHT Heavy)

Bank: Access Bank Client: Amina Bello, management consultant, Abuja (FCT — file with FIRS)

Gross: NGN 12,000,000. All from corporate clients with 10% WHT. WHT suffered: NGN 1,200,000. After CRA and expenses: tax per rates = NGN 950,000. Less WHT: NGN 1,200,000. Result: refund of NGN 250,000 (WHT > tax). File with FIRS for refund.

Example 3 — Zenith Bank (Port Harcourt, Physician)

Bank: Zenith Bank Client: Dr. Emeka Nwosu, physician, Port Harcourt, Rivers State

Gross: NGN 20,000,000 (hospital fees + private patients). Expenses: NGN 5,000,000. CRA: 200,000 + 4,000,000 = NGN 4,200,000. Pension: NGN 800,000. Taxable: 20,000,000 - 5,000,000 - 4,200,000 - 800,000 = NGN 10,000,000.

Tax: 21,000 + 33,000 + 75,000 + 95,000 + 336,000 + (10,000,000 - 3,200,000) x 24% = 560,000 + 1,632,000 = NGN 2,192,000

File with Rivers State IRS (not FIRS).

Example 4 — Kuda Bank (Lagos, Freelance Designer — Low Income)

Bank: Kuda Bank (digital) Client: Ngozi Eze, freelance designer, Lagos

Gross: NGN 600,000. Expenses: NGN 100,000. CRA: 200,000 + 120,000 = NGN 320,000. Taxable: 600,000 - 100,000 - 320,000 = NGN 180,000. Tax: 7% x 180,000 = NGN 12,600. Minimum tax: 1% x 600,000 = NGN 6,000. Pay NGN 12,600 (higher).

Example 5 — UBA (Lagos, Minimum Tax Scenario)

Bank: UBA Client: Tunde Adeyemi, consultant, Lagos

Gross: NGN 10,000,000. Expenses: NGN 9,000,000. CRA: 200,000 + 2,000,000 = NGN 2,200,000. Pension: NGN 500,000. Taxable: 10,000,000 - 9,000,000 - 2,200,000 - 500,000 = max(0, -1,700,000) = NGN 0. Computed tax: NGN 0. Minimum tax: 1% x 10,000,000 = NGN 100,000. Tax payable: NGN 100,000 (minimum tax applies).

Example 6 — First Bank (Kano, Multiple Income Sources)

Bank: First Bank Client: Ibrahim Musa, accountant, Kano, also earns rental income

Self-employment: NGN 6,000,000. Rental income: NGN 2,400,000. Total gross: NGN 8,400,000. CRA on total gross: 200,000 + 1,680,000 = NGN 1,880,000. All income aggregates. Apply expenses per source. Progressive rates on combined taxable income. File with Kano State IRS.

Section 5 — Tier 1 Rules (Apply Directly)

  • T1-NG-5 — Filing authority depends on state of residence — FCT (Abuja) residents file with FIRS. All other states file with the State Internal Revenue Service (SIRS). This is not optional. (T1-NG-5)
  • T1-NG-6 — Old personal allowance system is abolished — The pre-2020 system of personal allowance + children's allowance + dependent relative allowance was replaced by CRA. Never apply the old deductions. (T1-NG-6)

Section 9 — Onboarding Fallback

Filing authority:

"Nigerian personal income tax is administered by the Federal Inland Revenue Service (FIRS) for residents of the Federal Capital Territory (Abuja) and by the State Internal Revenue Service (SIRS) for residents of all other states. Where do you reside? This determines where you file your self-assessment return."

WHT certificates:

"If your clients deducted withholding tax (10% on professional fees, 5% on contracts) from your payments, you need the WHT certificates (credit notes) to claim these as credits against your annual tax. Contact each client to obtain their WHT certificates. Without them, the credit cannot be claimed."

CRA explanation:

"Under the Consolidated Relief Allowance (introduced by Finance Act 2020), you receive an automatic deduction of the higher of NGN 200,000 or 1% of your gross income, plus an additional 20% of your gross income. This replaces the old personal allowance, children's allowance, and dependent relative allowance. No documentation is needed for CRA — it is computed automatically."

Minimum tax:

"Even if your computed tax per the progressive rates is very low or zero (due to high expenses), you are still required to pay a minimum tax of 1% of your gross income. The minimum tax acts as a floor — you pay whichever is higher between computed tax and minimum tax."
