Tax Compliance Checklist for Mini Importers 2026

Nigeria's Tax Reform Act took full effect on January 1, 2026, fundamentally changing how mini importation businesses must operate. Non-compliance now carries penalties up to ₦100,000 for the first month and ₦50,000 for every subsequent month of default.

For mini importers, tax compliance isn't optional anymore—it's the law. Banks can freeze accounts, customs can hold goods, and you can face fines that wipe out your profits.

This checklist outlines the documents you need for tax compliance, the actions you must take, and how platforms like Proc360 help you stay compliant while focusing on growing your business.

5. Customs Clearance Compliance

✅ Honest Product Valuation

Never under-declare goods to reduce duties.

2026 penalty: Loss of capital allowances, tax deductions, and criminal prosecution.

NRS cross-checks:

• Supplier invoices vs customs declarations

• Bank transfers vs declared CIF values

• Historical pricing patterns

✅ Proper HS Code Classification

Use correct Harmonized System codes for products.

Wrong HS code = Wrong duty rate = Penalties + Interest

Get help: Customs brokers or platforms like Proc360 ensure accurate classification.

✅ Pay All Duties and Levies

What you'll pay:

• Import Duty (5-35% based on product)

• VAT (7.5% on CIF + duty)

• NHIL (2.5%)

• GETFund Levy (2.5%)

• ECOWAS Levy (0.5%)

• AU Levy (0.2%)

Keep: All customs payment receipts for VAT recovery and tax filing.

Common Compliance Mistakes to Avoid

❌ Waiting to register TIN → Payments blocked, goods stuck ❌ Not filing returns even when exempt → ₦100,000+ fines ❌ Mixing personal and business accounts → Triggers audits ❌ Under-declaring product values → Loss of tax benefits + penalties ❌ No digital records → Can't prove expenses, pay more tax ❌ Ignoring VAT recovery → Losing 7.5% of every import cost

1. Business Registration & Tax Identification

✅ Register Your Business with CAC

Even if operating informally before 2026, you now need proper registration:

• Business Name Registration: ₦10,500 (valid 7 years)

• Limited Company: ₦35,000-₦50,000 (for serious scaling)

Why it matters: Required for TIN generation, business bank accounts, and tax exemption claims.

✅ Obtain Tax Identification Number (TIN)

TIN registration is now mandatory for ALL businesses making over ₦500,000 annually.

How to get it:

• Register online at https://tin.jtb.gov.ng/ (FREE)

• Auto-generated if you have CAC registration

• Activate at the nearest FIRS office within 7 days

Without TIN: ❌ Banks block international payments ❌ Cannot process Form M for imports ❌ Customs holds goods at port ❌ Penalties of ₦50,000+

✅ Link TIN to All Accounts

• Bank accounts (corporate and personal used for business)

• Payment platforms (Paystack, Flutterwave)

• Clearing agent records

• Supplier payment systems

2026 requirement: Banks must verify TIN for all business transactions over ₦5 million monthly.

2. Import Documentation Compliance

✅ Form M (Import Permit)

Required for ALL imports, processed through your bank.

What you need:

• CAC certificate

• TIN certificate

• Tax Clearance Certificate

• Proforma Invoice from Chinese supplier

• Domiciliary account

Processing time: 2-5 days Validity: 6 months (extendable for 180 days)

✅ SONCAP Certificate

Mandatory for regulated products (electronics, machinery, appliances, toys).

Process:

• Product Certificate (PC) issued first

• SONCAP Certificate (SC) issued for specific shipment

Cost: $200-$500 depending on value Without it: Goods seized at port

✅ Tax Clearance Certificate

Shows you're tax-compliant with Nigeria Revenue Service.

How to get:

• Register with NRS (requires TIN)

• File tax returns (even if exempt)

• Apply via NRS portal

• Valid for 12 months

Required for:

• Large import shipments (over $10,000)
