Introduction
Chioma just landed her first corporate job in Lagos with a monthly salary of ₦250,000. When she received her first payslip, she noticed a deduction labeled "PAYE" for ₦32,142. Confused and slightly panicked, she wondered: Is this legal? Am I paying too much? Do I need to do anything else?
Meanwhile, her friend Adebayo recently registered his graphic design business. He keeps hearing about TIN, VAT, withholding tax, and multiple tax authorities. He's overwhelmed and worried about making mistakes that could cost him heavily.
If you're like Chioma or Adebayo, you're not alone. Nigeria's tax system can seem intimidating, especially when you're just starting out. The good news? Once you understand the basics, tax compliance becomes straightforward.
This guide will walk you through everything you need to know about Nigerian taxes as a beginner—which taxes apply to you, how they're calculated, when they're due, and what happens if you miss deadlines. By the end, you'll have the confidence to handle your tax obligations like a pro.
Who Pays Tax in Nigeria?
Let's start with the most important question: Do you need to pay tax?
The simple answer: If you earn income in Nigeria, you likely have tax obligations.
This includes:
• Salaried employees working for companies, NGOs, or government • Self-employed professionals like consultants, freelancers, and tradespeople • Business owners running registered companies or sole proprietorships • Property owners earning rental income • Investors receiving dividends or interest above certain thresholds • Side hustlers with additional income streams beyond their main job
The myth that "only big companies pay tax" or "small businesses are exempt" is dangerous. While small businesses enjoy certain reliefs (we'll cover this), everyone with taxable income has compliance responsibilities under the Personal Income Tax Act (PITA) Section 3 and Companies Income Tax Act (CITA) Section 9.
The Three Main Tax Authorities You Need to Know
Nigeria's tax system involves multiple authorities, and knowing who handles what will save you confusion. This division of responsibilities is established under the Taxes and Levies (Approved List for Collection) Act CAP T2 LFN 2004.
Federal Inland Revenue Service (FIRS)
FIRS is the federal tax authority that collects:
• Companies Income Tax (from all registered businesses) • Value Added Tax (VAT) • Withholding Tax on federal contracts and certain transactions • Personal Income Tax for residents of the Federal Capital Territory (Abuja) • Education Tax (from all companies) • Stamp Duties on certain instruments
Think of FIRS as handling business taxes at the federal level.
State Internal Revenue Service (SIRS)
Each of Nigeria's 36 states has its own tax authority (like LIRS in Lagos, KADIRS in Kaduna, or RIRS in Rivers). They collect:
• Personal Income Tax from individuals and unincorporated businesses resident in the state • Withholding Tax on state contracts • Business premises registration fees • Development levies (where applicable)
Your state tax office handles your personal income tax if you're employed or self-employed.
The Key Difference
If you're an individual earning salary or running an unincorporated business, you deal with your State tax authority.
If you own a registered company (Limited by shares or guarantee), you deal primarily with FIRS for corporate taxes, plus your state authority for PAYE on employees.
Understanding Your Tax Identification Number (TIN)
Before paying any tax, you need a Tax Identification Number—your unique tax identity for life, as mandated by the Federal Inland Revenue Service (Establishment) Act 2007, Section 25.
What is TIN?
Your TIN is a unique number (format: 12345678-0001 for individuals, 01234567-0001 for companies) that identifies you to tax authorities. Think of it like your BVN but for taxes.
Who Needs TIN?
Everyone who earns taxable income:
• Individuals earning above the minimum taxable threshold • All registered businesses (mandatory before company registration) • Self-employed professionals and freelancers • Anyone conducting significant financial transactions
How to Get Your TIN
For Individuals:
- Visit your State Internal Revenue Service website or FIRS portal (for FCT residents)
- Complete online TIN registration form with personal details
- Upload required documents (national ID, utility bill, passport photo)
- Submit application—TIN is usually issued within 24-48 hours
- Print your TIN certificate or save the digital copy
For Companies:
- Visit FIRS website (firs.gov.ng) or use TaxPro-Max platform
- Complete corporate TIN registration with company details
- Upload CAC documents, directors' information, and business address proof
- Receive TIN immediately or within 48 hours
- TIN is now required before CAC company registration from 2024
Important: TIN registration is completely free. Beware of agents charging exorbitant fees. You can do it yourself online.
When Do You Need Your TIN?
• Opening a corporate bank account • Receiving payments from government or large corporations • Importing or exporting goods • Applying for business licenses or permits • Filing tax returns • Bidding for contracts • Processing international transactions above certain thresholds
Types of Taxes That Affect You
Let's break down the main taxes you'll encounter and who pays what.
Personal Income Tax (PIT)
Who Pays: All individuals earning income in Nigeria (per PITA Section 3)
What's Taxed: Employment income (salaries, bonuses, allowances), business profits, professional fees, rental income, and certain investment income
How It Works:
Nigeria uses a progressive tax system, meaning higher income is taxed at higher rates. Your income is taxed in brackets according to the PITA Sixth Schedule as amended:
• First ₦300,000 of taxable income: 7% tax • Next ₦300,000 (₦300,001 - ₦600,000): 11% tax • Next ₦500,000 (₦600,001 - ₦1,100,000): 15% tax • Next ₦500,000 (₦1,100,001 - ₦1,600,000): 19% tax • Next ₦1,600,000 (₦1,600,001 - ₦3,200,000): 21% tax • Income above ₦3,200,000: 24% tax
But wait—there's good news! Before calculating tax, you get the Consolidated Relief Allowance (CRA).
Understanding Consolidated Relief Allowance (CRA)
This is tax-free income automatically deducted before calculating your tax, as provided under PITA Section 33.
CRA = Higher of ₦200,000 or 1% of gross income + 20% of gross income
Example: Tunde's Tax Calculation
Tunde earns ₦3,000,000 annually (₦250,000 monthly) as a bank employee.
Step 1: Calculate CRA • 1% of ₦3,000,000 = ₦30,000 • 20% of ₦3,000,000 = ₦600,000 • Total CRA = ₦630,000
Step 2: Calculate Taxable Income • Gross Income: ₦3,000,000 • Minus CRA: ₦630,000 • Taxable Income: ₦2,370,000
Step 3: Apply Tax Rates (per PITA Sixth Schedule) • First ₦300,000 @ 7% = ₦21,000 • Next ₦300,000 @ 11% = ₦33,000 • Next ₦500,000 @ 15% = ₦75,000 • Next ₦500,000 @ 19% = ₦95,000 • Remaining ₦770,000 @ 21% = ₦161,700
Total Annual Tax: ₦385,700 Monthly PAYE Deduction: ₦32,142
Tunde's employer automatically calculates and deducts this from his salary every month, then remits to the Lagos State Internal Revenue Service within 10 days as required by PITA Section 49.
Pay-As-You-Earn (PAYE)
Who Pays: Salaried employees
How It Works:
If you're employed, you don't calculate your tax—your employer does it for you. This system is called PAYE (Pay-As-You-Earn), governed by PITA Section 49.
Your employer:
- Calculates your tax monthly using the rates above
- Deducts it from your salary before payment
- Remits the deducted tax to your State tax authority within 10 days
- Issues you an annual tax certificate showing total tax paid
What You Need to Do:
• Verify the PAYE deduction on your payslip is correctly calculated • Ensure your employer is actually remitting (request proof annually) • If you have other income sources, file an annual self-assessment return • Keep your TIN and annual tax receipts for records
Common Question: "My employer deducts PAYE. Do I still need to file a return?"
Answer: If salary is your ONLY income source, no additional filing is usually required. However, if you earn rental income, consultancy fees, dividends, or run a side business, you MUST file an annual self-assessment return declaring all income sources.
Companies Income Tax (CIT)
Who Pays: All registered companies (limited liability companies)
What's Taxed: Company profits after deducting allowable business expenses
Tax Rates (Good News for Small Businesses!):
The Finance Act 2019 introduced graduated rates based on annual turnover (per CITA Section 9 as amended):
• Small companies (turnover below ₦25 million): Exempt from standard 30% CIT rate • Medium companies (turnover ₦25 million to ₦100 million): 20% CIT • Large companies (turnover above ₦100 million): 30% CIT
Important Clarification: While small companies are exempt from the standard CIT rate, they are NOT completely tax-free.
Example: Fatima's Trading Business
Fatima owns "Sunrise Imports Ltd" with these annual figures:
• Total sales (turnover): ₦15,000,000 • Business expenses: ₦10,000,000 • Net profit: ₦5,000,000
Tax Calculation:
Since turnover is ₦15 million (below ₦25 million threshold), Fatima's company is exempt from the standard 30% CIT rate under the small company regime.
However, the company is still liable for:
1. Minimum Tax (per CITA Section 33): • 0.5% of turnover = 0.5% × ₦15,000,000 = ₦75,000, OR • 0.25% of gross assets (whichever is higher) • Subject to minimum of ₦25,000
2. Education Tax (per Education Tax Act Cap E4 LFN 2004): • 2% of assessable profit = 2% × ₦5,000,000 = ₦100,000
Total tax liability: ₦175,000 annually
While this is significantly lower than the standard 30% CIT (which would have been ₦1,500,000), it's important to understand that small companies are exempt from the standard CIT rate but not from minimum tax provisions under CITA Section 33.
This is a huge relief for small businesses! The government designed this to encourage formalization.
Minimum Tax
Even if your company makes no profit or is exempt from standard CIT rates, you pay minimum tax under CITA Section 33:
• 0.5% of gross turnover, OR • 0.25% of gross assets (whichever is higher) • Minimum of ₦25,000 for any company
This ensures every company contributes something to national development.
Value Added Tax (VAT)
Who Pays: Businesses selling goods or services
Current Rate: 7.5% (increased from 5% in February 2020 per VAT Act Section 2 as amended by Finance Act 2019)
How It Works:
VAT is a consumption tax charged on most goods and services. Here's the flow:
- You sell a product/service for ₦10,000
- You charge customer ₦10,750 (₦10,000 + 7.5% VAT)
- You keep ₦10,000 and owe FIRS ₦750
- BUT—if you paid ₦400 VAT when buying materials (input VAT), you can deduct it
- You remit only ₦350 (₦750 - ₦400) to FIRS
Do You Need to Register for VAT?
Mandatory registration if your annual turnover exceeds ₦25 million (per VAT Act Section 10 as amended).
Voluntary registration is allowed even below this threshold if you want to reclaim input VAT on your purchases.
Filing: Monthly VAT returns must be filed within 21 days after month-end, even if no sales occurred (file "nil return").
Example: Emeka's Restaurant
Emeka owns "Greenfield Eatery Ltd" with monthly sales of ₦5,000,000.
• Annual turnover: ₦60,000,000 (exceeds ₦25M, so VAT registration mandatory) • VAT collected from customers monthly: 7.5% × ₦5,000,000 = ₦375,000 • VAT paid on food supplies monthly (input VAT): ₦150,000 • Net VAT to remit: ₦375,000 - ₦150,000 = ₦225,000
Emeka files monthly VAT returns online via TaxPro-Max and pays ₦225,000 to FIRS by the 21st of the following month.
Important: Keep all purchase invoices showing VAT paid—you need them to claim input VAT credits.
Withholding Tax (WHT)
Who's Affected: Freelancers, consultants, contractors, landlords
How It Works:
When you provide services to government agencies or large corporations, they deduct a percentage of your payment as withholding tax before paying you (per CITA Section 78 and Third Schedule).
Common WHT Rates:
• Contracts/supplies: 5% • Professional/technical/management services: 10% • Rent on property: 10% • Dividends: 10% (per CITA Section 80) • Interest: 10%
Example: Aisha the Consultant
Aisha provides HR consulting to a bank. Her invoice is ₦1,000,000.
• Bank deducts 10% WHT = ₦100,000 • Bank pays Aisha: ₦900,000 • Bank remits ₦100,000 to FIRS within 30 days • Bank issues Aisha a WHT certificate
Critical Understanding: This ₦100,000 is NOT Aisha's final tax—it's an advance payment!
At year-end, when Aisha files her personal income tax return:
• Total annual income from all clients: ₦10,000,000 • Business expenses: ₦3,000,000 • Net taxable income (after CRA): ₦5,930,000 • Total tax due: ₦1,115,100 • Minus WHT already deducted by clients: ₦800,000 • Balance to pay: ₦315,100
Always collect WHT certificates from clients—they're your proof of advance tax payment!
Education Tax
Who Pays: All registered companies (per Education Tax Act Cap E4 LFN 2004)
Rate: 2% of assessable profit
Purpose: Funds the Tertiary Education Trust Fund (TETFund)
Even if you pay zero CIT (like small companies exempt from the standard rate), you still pay Education Tax. It's calculated alongside your Companies Income Tax return and paid to FIRS.
Key Tax Deadlines You Must Know
Missing deadlines triggers penalties that escalate quickly. Mark these dates:
For Employees (PAYE)
Employer's deadline: Within 10 days after month-end (per PITA Section 49)
• Example: January salaries paid? PAYE remittance due by February 10 • Penalty for late remittance: ₦25,000 first month + ₦5,000 each subsequent month + 10% annual interest
For Self-Employed/Businesses (Personal Income Tax)
Filing deadline: Within 90 days after your accounting year-end (per PITA Section 81)
• If you use calendar year (January-December), returns due by March 31 • Penalty: ₦25,000 first month + ₦5,000 each subsequent month
For Companies (CIT)
Filing deadline: Within 6 months after company's accounting year-end (per CITA Section 55)
• Must include audited financial statements • Example: Year-end December 31? Returns due by June 30 • Penalty: ₦25,000 first month + ₦5,000 each subsequent month + 10% annual interest on unpaid tax + 1% monthly penalty (per CITA Section 77)
For VAT
Filing deadline: Within 21 days after month-end (per VAT Act Section 10 as amended)
• Example: March VAT return due by April 21 • File even if no sales (nil return) • Penalty: ₦50,000 first month + ₦25,000 subsequent months + 10% annual interest
For Withholding Tax
Remittance deadline: Within 30 days from the date of deduction for most WHT types (per CITA Third Schedule)
• This applies to WHT on contracts, professional services, dividends, interest, and rent • Companies withholding under PAYE remit within 10 days after month-end • Penalty: 10% annual interest + potential 200% penalty on tax not remitted
Pro Tip: File Even If You Can't Pay
If facing cash flow challenges, still file your returns on time to avoid late filing penalties. Then negotiate a payment plan with the tax authority. Filing late attracts additional penalties on top of late payment interest.
Tax Clearance Certificate: Your Business Passport
A Tax Clearance Certificate (TCC) proves you're tax compliant. It's valid for 12 months from issuance.
Why You Need It
You cannot:
• Bid for government contracts • Open or operate corporate bank accounts • Obtain business licenses or permits • Process work permits or certain visas • Participate in public procurement • Access government incentives or loans
How to Obtain TCC
For Individuals:
- File your annual tax returns with State tax authority
- Pay all outstanding taxes
- Apply for TCC online or at tax office
- Pay TCC processing fee (typically ₦5,000-₦10,000 depending on state)
- Receive certificate within 7-14 days
For Companies:
- File CIT returns with FIRS
- File personal income tax for directors/shareholders with State authority
- Clear all outstanding tax liabilities
- Apply online via TaxPro-Max
- Pay processing fee
- Download e-certificate or collect physical copy
Important: Start your TCC application at least 1 month before you need it for contracts or licenses. Processing can take 2-4 weeks during busy periods.
Common Tax Mistakes to Avoid
Mistake 1: "I'm Too Small to Pay Tax"
Reality: Size doesn't determine tax obligation—income does. Even side hustles earning ₦500,000 annually are taxable under PITA. The good news? Small companies are exempt from standard CIT rates, but you still need to register, pay minimum tax, and file returns.
Mistake 2: Ignoring Multiple Income Sources
Scenario: Tunde earns ₦200,000 monthly salary (PAYE deducted) but also makes ₦1,500,000 annually from weekend consultancy.
Mistake: Thinking PAYE covers everything.
Reality: Tunde must file self-assessment return declaring both salary and consultancy income. He'll owe additional tax on the consultancy income after claiming WHT credits and allowable expenses.
Mistake 3: Not Keeping Business Records
Problem: Claiming business expenses without receipts or invoices.
Reality: During tax audits, you must prove expenses with documentation. No receipts = expenses disallowed = higher tax bill. Keep all records for at least 6 years.
Mistake 4: Missing VAT Registration Threshold
Scenario: Your business grows from ₦20M to ₦35M annual turnover.
Mistake: Not registering for VAT because you didn't realize you crossed the ₦25M threshold.
Reality: Penalties for non-registration can reach 150% of VAT that should have been collected. Monitor your turnover and register proactively.
Mistake 5: Assuming Employer Remits Your PAYE
Problem: Some employers deduct PAYE but don't remit to tax authorities.
Impact: Tax authority holds YOU responsible, not your employer. You could face demands for unpaid taxes plus penalties years later.
Solution: Request annual tax receipts from your employer showing remittances. If your employer isn't remitting, report to State tax authority—they'll compel compliance.
Mistake 6: Using Incorrect Tax Authority
Example: Registering your personal income tax with FIRS instead of State authority, or trying to pay CIT to your state office.
Solution: Remember the division under Taxes and Levies (Approved List for Collection) Act—FIRS for companies and federal taxes; State for personal income tax of individuals and unincorporated businesses.
Mistake 7: Forgetting to File "Nil" Returns
Scenario: Your business had no activity or made losses this year.
Mistake: Not filing returns because there's no tax to pay.
Reality: You must file "nil returns" showing zero income or losses. Non-filing still attracts penalties regardless of whether tax is due.
Understanding Tax Reliefs and Deductions
Beyond CRA, certain reliefs can reduce your tax burden:
For Individuals
Life Assurance Relief (per PITA) • Premium paid on life insurance policies (own life, spouse, or children under 18) • Relief: Lower of actual premium or 20% of gross income • Maximum relief: ₦500,000 per year
Pension Contributions Relief • Mandatory pension contributions (minimum 8% of monthly emolument for employees) • Completely tax-free—deducted before calculating taxable income
National Housing Fund (NHF) Contributions • 2.5% of basic salary contributed to NHF • Exempt from tax
For Businesses
Allowable Business Expenses (per CITA):
• Staff salaries and wages • Rent for business premises • Utility bills (electricity, water, internet for business use) • Professional fees (accounting, legal, consultancy) • Equipment and machinery (capital allowances apply) • Marketing and advertising costs • Transportation and logistics • Bank charges and interest on business loans • Repairs and maintenance
Not Allowed:
• Personal expenses • Capital expenditure (but qualify for capital allowances instead) • Entertainment expenses above certain limits • Non-business related costs • Fines and penalties
Capital Allowances:
Instead of deducting full cost of equipment immediately, you claim capital allowances:
• Initial Allowance: 50% in first year for plant and machinery • Annual Allowance: Percentage of cost spread over asset's life • Buildings, vehicles, computers, furniture all qualify
Tax Incentives for Startups and Small Businesses
Pioneer Status
Qualifying industries (technology, agriculture, manufacturing, etc.) can get 3-5 years tax holiday on company income tax.
How to Apply: • Submit application to Nigerian Investment Promotion Commission (NIPC) • Demonstrate you're in a pioneer industry • Show significant investment and employment creation
Small Company Relief
As mentioned earlier, companies with turnover below ₦25M are exempt from the standard 30% CIT rate (per CITA Section 9 as amended by Finance Act 2019)—though minimum tax provisions under CITA Section 33 still apply.
Rural Investment Allowance
Businesses located in rural areas (at least 20km from major cities) get additional tax deductions to encourage development outside urban centers.
Export Incentives
Export-oriented businesses enjoy various tax incentives including tax-free profits from export proceeds in certain sectors.
Navigating Tax Audits: What to Expect
Tax authorities conduct audits to verify accuracy of returns. Here's what happens:
Types of Audits
Desk Audit: Tax office reviews your filed returns and requests clarification on specific items via correspondence.
Field Audit: Tax officers visit your business premises to examine books, records, and physical operations.
Random Audit: Periodic checks to ensure compliance across taxpayer base.
Targeted Audit: Triggered by red flags like significant discrepancies, complaints, or industry-specific focus.
What Triggers Audits
• Significant unexplained changes in revenue or expenses • Consistently reporting losses • Lifestyle inconsistent with declared income (especially for high-net-worth individuals) • Third-party information (banks report certain transactions to FIRS) • Random selection • Industry-wide audits
Your Rights During Audits
• Right to be represented by a tax professional • Right to reasonable notice before field audits • Right to appeal audit findings • Right to confidentiality of tax information • Right to request audit conclusion within reasonable timeframe
Best Practices
• Keep organized records always—don't scramble when audit notice arrives • Respond promptly to all correspondence • Be cooperative but don't volunteer information not requested • Engage a tax consultant for complex audits • If you discover errors, file amended returns proactively
Getting Help: When to Hire a Tax Professional
While basic tax compliance is manageable independently, consider professional help if:
• Your business turnover exceeds ₦10 million annually • You have multiple income sources • You're starting a company and need tax structure advice • Facing a tax audit or dispute • Operating in complex industries (oil & gas, banking, telecoms) • Expanding internationally • Seeking tax incentives or pioneer status
Cost vs. Benefit:
• Tax consultant fees: ₦50,000-₦500,000 annually depending on complexity • Cost of penalties for non-compliance: Often ₦500,000-₦5,000,000+ in fines, interest, and back taxes • Peace of mind: Priceless
Many accountants offer monthly retainer services (₦20,000-₦100,000/month) handling all tax compliance, freeing you to focus on your business.

Key Takeaways
• Tax applies to everyone earning income in Nigeria—from salaried employees to freelancers to businesses of all sizes. Ignorance is not an excuse under PITA Section 3 and CITA Section 9.
• Get your TIN immediately—it's free, takes 24-48 hours, and you'll need it for virtually every financial transaction. Register online at your state tax website or FIRS portal as mandated by the FIRS Establishment Act Section 25.
• Understand the distinction: FIRS handles company taxes and VAT; State tax authorities handle personal income tax per the Taxes and Levies (Approved List for Collection) Act. Going to the wrong office wastes your time.
• Small businesses enjoy major reliefs—exemption from standard 30% CIT rate if turnover is below ₦25 million (per CITA Section 9 as amended by Finance Act 2019), though minimum tax provisions under CITA Section 33 still apply.
• PAYE is automatic for employees (per PITA Section 49), but if you have side income, you must file a self-assessment return declaring all income sources.
• Deadlines are serious—late filing starts at ₦25,000 penalty plus ₦5,000 monthly (per PITA Section 81 and CITA Section 77); late payment attracts 10% annual interest plus additional penalties. Filing on time is always cheaper than penalties.
• Keep meticulous records for 6 years—receipts, invoices, bank statements, contracts. Tax authorities can audit retrospectively, and you must prove every expense you claim.
• Tax Clearance Certificate is non-negotiable for business growth—you need it for contracts, licenses, permits, and many financial transactions. Renew annually.
• Withholding Tax is an advance payment, not final tax—collect all WHT certificates (per CITA Third Schedule) and claim them as credits when filing your annual return.
• Professional help pays for itself—if your tax situation is complex, engaging an accountant or tax consultant (₦50,000-₦500,000 annually) is far cheaper than penalties and errors.
Frequently Asked Questions
Q: I just started earning. How do I know if I need to pay tax?
A: If you earn above ₦300,000 annually (about ₦25,000 monthly), you're in the taxable bracket per PITA Sixth Schedule. However, thanks to CRA (per PITA Section 33), effective minimum taxable income is higher—around ₦900,000-₦1,000,000 annually before owing significant tax.
Q: Can I reduce my tax bill legally?
A: Yes! Claim all entitled reliefs (CRA, life insurance, pension contributions per PITA), deduct all allowable business expenses if self-employed (per CITA), and consider tax-efficient structures like incorporating as a small company (exempt from standard CIT rate below ₦25M turnover per CITA Section 9 as amended).
Q: What happens if I haven't filed taxes for several years?
A: Contact the tax authority immediately. They may assess you based on estimated income and impose penalties per PITA Section 81 or CITA Section 77, but voluntary disclosure often results in more lenient treatment than being caught during enforcement. Many states offer periodic tax amnesty programs waiving penalties for those coming forward.
Q: Do I need a tax consultant or can I do it myself?
A: If you're a salaried employee with no other income, you can manage yourself—your employer handles PAYE. If you're self-employed or run a business, basic compliance is doable with online resources, but professional help is advisable as your income grows beyond ₦5-10 million annually or if you face audits.
Q: How long does TIN registration take?
A: Online registration typically takes 24-48 hours. You complete the form, upload documents, and receive your TIN electronically. Physical certificates may take 1-2 weeks if you require them, but the electronic version is valid for all purposes.
Q: Is VAT mandatory for all businesses?
A: No. VAT registration is mandatory only when your annual turnover exceeds ₦25 million (per VAT Act Section 10 as amended). Below this threshold, registration is voluntary. However, if you expect to cross the threshold, register proactively rather than waiting to be penalized for late registration.
Q: What if my employer doesn't remit my PAYE?
A: Legally, you remain liable for unpaid taxes even if your employer deducted them. Report non-compliant employers to your State tax authority under PITA Section 49—they have enforcement powers to compel remittance. Request annual remittance receipts from your employer as proof.
Q: Can I claim tax refunds if too much was deducted?
A: Yes. If WHT or PAYE deducted exceeds your actual tax liability (common when you have allowable business expenses or multiple employers over-deducted), file your return claiming a refund. Processing takes 3-6 months typically, so file early.
Q: Do I need separate TINs for my business and personal taxes?
A: No. As an individual, you have one TIN for life (per FIRS Establishment Act Section 25) used for all personal tax matters. Your registered company gets its own corporate TIN. If you're a sole proprietor (unincorporated business), you use your personal TIN.
Q: What's the easiest way to stay compliant?
A: Set up monthly reminders for filing deadlines, use accounting software to track income/expenses automatically, separate business and personal finances, and consider hiring a bookkeeper for ₦15,000-₦30,000 monthly to handle routine compliance while you focus on growing your business.

The Nigerian government is increasingly focused on improving tax administration and expanding the tax net.
