How to Get Your TIN and File Taxes in Nigeria (2026 Guide)
Taxes in Nigeria can feel confusing, but they do not have to be. Whether you are an employee, a freelancer, or a business owner, this guide walks you through getting your Tax Identification Number (TIN), understanding your obligations, and filing correctly.
What Is a TIN?
A Tax Identification Number (TIN) is a unique number assigned to every taxpayer in Nigeria by the Federal Inland Revenue Service (FIRS) or your State Internal Revenue Service (SIRS). It is required for:
- Opening a corporate bank account
- Bidding for government contracts
- Processing CAC business registration
- Filing annual tax returns
- Certain international transactions
How to Get a TIN
For Individuals (JTB TIN)
- Visit the **FIRS TIN registration portal** at jtb.gov.ng/tin-registration
- Fill in your personal details: name, address, phone, email
- Provide your BVN or NIN for identity verification
- Submit and receive your TIN via email and SMS
- The process is free and usually instant online
For Businesses
- Register your business with CAC first
- Visit the FIRS office or use the FIRS e-filing portal
- Submit your CAC certificate, director IDs, and utility bill
- Your business TIN is issued (usually same day online, 2-3 days in person)
Types of Taxes in Nigeria
For Employees (PAYE)
Pay As You Earn is deducted from your salary by your employer. If your employer handles PAYE correctly, you may not need to do much else. But you should:
- Verify your employer is actually remitting PAYE
- Request your annual PAYE receipt
- File a personal return if you have additional income
For Self-Employed / Freelancers
You are responsible for filing your own taxes. The personal income tax rates are:
| Annual Income | Tax Rate |
|---|---|
| First N300,000 | 7% |
| Next N300,000 | 11% |
| Next N500,000 | 15% |
| Next N500,000 | 19% |
| Next N1,600,000 | 21% |
| Above N3,200,000 | 24% |
For Businesses
- **Companies Income Tax (CIT)**: 30% for large companies, 20% for medium, 0% for small (under N25M revenue)
- **VAT**: 7.5% on goods and services
- **Withholding Tax**: 5-10% deducted at source on certain payments
How to File Your Tax Return
Online Filing (Recommended)
- Visit the **FIRS e-filing portal** at taxpromax.firs.gov.ng
- Log in with your TIN
- Select the appropriate return type
- Fill in your income details
- Upload supporting documents if required
- Submit and download your receipt
Filing Deadlines
| Taxpayer Type | Deadline |
|---|---|
| Individuals | March 31 (for previous year) |
| Companies | June 30 (6 months after year-end) |
| VAT Returns | 21st of following month |
Penalties for Non-Filing
- Individuals: N500,000 fine or 5% of tax owed
- Companies: N250,000 first month, N100,000 each subsequent month
- Late VAT: 5% per annum plus interest
Tax Reliefs and Deductions
Nigerians are entitled to several tax reliefs:
- **Consolidated Relief Allowance**: N200,000 + 20% of gross income (automatic)
- **Pension contributions**: Tax-deductible up to 8% of salary
- **NHF contributions**: 2.5% of salary, tax-deductible
- **Life insurance premiums**: Tax-deductible
- **NHIS contributions**: Tax-deductible
These reliefs can significantly reduce your effective tax rate.
State vs Federal Tax
- **FIRS** handles federal taxes: Companies Income Tax, VAT, petroleum profits tax
- **SIRS** handles state taxes: Personal income tax, withholding tax on individuals, stamp duties
If you are employed, your PAYE goes to the state where you reside, not where your company is registered.
Common Tax Mistakes
- **Thinking PAYE means you are fully compliant** -- if you have side income, you must declare it separately.
- **Not keeping receipts** -- you need documentation for deductions and in case of audit.
- **Ignoring TIN registration** -- even if you earn below the tax threshold, having a TIN is essential for many services.
- **Missing deadlines** -- penalties compound. File on time even if you cannot pay yet.
- **Using unqualified tax agents** -- hire a registered tax practitioner, not a random "tax consultant."

Our Take
