Understanding Withholding Tax Contractors Nigeria 2026

Withholding tax (WHT) is a prepayment of income tax. When you pay contractors or vendors, you deduct a percentage and remit it to FIRS on their behalf.

Think of yourself as a tax collector. You’re not keeping the money — you’re helping FIRS collect taxes at the source.

Key difference: Contractors get WHT deducted. Employees get PAYE deducted. The distinction matters for compliance.

WHT Rates Under NTA 2025

Service Type	WHT Rate	Example Payment
Professional/Technical/Consultancy	5%	Legal, IT, marketing services
Rent (Commercial property)	10%	Office rent, warehouse lease
Dividends	10%	Shareholder distributions
Interest on loans/deposits	10%	Bank interest, loan interest
Construction services	2.5%	Building, renovation, infrastructure
Supply of goods	2%	Equipment, inventory, materials

[SOURCE: NTA 2025]

The 5% rate on consultancy services catches most businesses. Your web developer, accountant, and marketing consultant all fall under this category.

Step 1: Confirm Contractor Status

Before deducting WHT, confirm they’re actually a contractor, not an employee.

Contractors typically:

• Work on specific projects with defined deliverables
• Use their own equipment and resources
• Set their own schedules
• Invoice for completed work
• Have multiple clients

Employees typically:

• Work regular hours set by you
• Use company equipment
• Follow company processes daily
• Receive monthly salaries
• Work exclusively for your business

Pro tip: When in doubt, treat them as an employee. FIRS is stricter about missing PAYE than excess WHT deductions.

Step 2: Verify Their TIN

Every contractor must provide their Tax Identification Number before payment. No TIN, no payment — it’s that simple.

How to verify a TIN:

1. Visit the FIRS TIN verification portal

2. Enter the contractor’s TIN

3. Confirm their business name matches your records

Common mistake: Accepting expired or invalid TINs. Always verify before processing payment.

Step 3: Calculate WHT Amount

Formula: Payment Amount × WHT Rate = WHT to Deduct

Example 1 — Consultancy Service:

• Invoice amount: ₦2,000,000
• WHT rate: 5%
• WHT deduction: ₦2,000,000 × 5% = ₦100,000
• Amount paid to contractor: ₦1,900,000
• Amount remitted to FIRS: ₦100,000

Example 2 — Office Rent:

• Monthly rent: ₦500,000
• WHT rate: 10%
• WHT deduction: ₦500,000 × 10% = ₦50,000
• Amount paid to landlord: ₦450,000
• Amount remitted to FIRS: ₦50,000

The contractor receives less than their invoice amount, but they get credit for the WHT when filing their annual tax returns.

Step 4: Make Payment and Issue WHT Certificate

After deducting WHT:

1. Pay the contractor the net amount (invoice minus WHT)

2. Issue a WHT certificate showing the deduction

3. Keep detailed records for your monthly remittance

WHT Certificate must include:

• Your company details and TIN
• Contractor details and TIN
• Service description
• Gross amount and WHT rate
• WHT amount deducted
• Net amount paid
• Payment date

Pro tip: Use standardized WHT certificate templates. Contractors need these for their tax filings.

Step 5: Remit WHT to FIRS

Deadline: 21st of the month following payment [SOURCE: NTA 2025]

Example timeline:

• January payments: Remit by February 21st
• February payments: Remit by March 21st

How to remit:

1. Log into FIRS online platform

2. Generate WHT remittance advice

3. Make payment via bank transfer or online

4. Upload payment evidence and WHT schedule

5. Print acknowledgment receipt

Common mistake: Waiting until year-end to remit WHT. This triggers immediate penalties and interest charges.

Cost Breakdown

Item	Cost	Notes
FIRS WHT remittance	₦0	Free government service
Bank transfer charges	₦50-₦500	Varies by bank and amount
WHT certificate printing	₦100-₦500	Per contractor, per payment
Professional consultation	₦5,000-₦15,000	One-time setup guidance
Total monthly cost	₦500-₦2,000	For 5-10 contractor payments

Common WHT Mistakes (And How to Avoid Them)

1. Mixing Up WHT and PAYE Rates

The mistake: Using PAYE tax bands (0% to 25%) for contractor payments instead of flat WHT rates.

The fix: Contractors get flat WHT rates. Employees get progressive PAYE rates. Keep them separate.

2. Forgetting WHT on Rent Payments

The mistake: Paying office rent in full without deducting 10% WHT.

The fix: All commercial rent payments require 10% WHT deduction, even for corporate landlords.

3. Late Remittance

The mistake: Collecting WHT throughout the month but remitting after the 21st deadline.

The fix: Set calendar reminders for the 15th of each month. Give yourself buffer time for bank processing.

4. Missing WHT Certificates

The mistake: Deducting WHT but not giving contractors proper documentation.

The fix: Issue WHT certificates immediately after payment. Contractors need these for their annual returns.

5. Applying Wrong Rates to Mixed Services

The mistake: A contractor provides both consultancy (5%) and supplies equipment (2%) but you apply one rate to everything.

The fix: Split invoices by service type and apply the correct WHT rate to each component.

Employee vs Contractor: When WHT Applies

This distinction trips up many businesses. Here’s the practical test:

Apply WHT when:

• They invoice you for completed projects
• They work from their own location most days
• They provide specialized skills for specific deliverables
• They have other clients besides you
• You pay them per project or milestone

Apply PAYE when:

• You pay them monthly salaries
• They work your regular business hours
• They use your equipment and workspace daily
• You control how they do their work
• They’re integrated into your daily operations

Gray area example: A part-time graphic designer who works 3 days per week in your office using your computer but invoices monthly for design projects.

Safe approach: Treat them as an employee and apply PAYE. FIRS prefers over-caution on employment classification.

Penalties for WHT Non-Compliance

For failure to deduct WHT: Up to ₦5,000,000 fine [SOURCE: NTA 2025]

For late remittance: 10% penalty on the WHT amount plus daily interest

For wrong rates: Difference between correct and incorrect amounts, plus 10% penalty

Real example: You pay a consultant ₦5 million without deducting WHT. FIRS can fine you up to ₦5 million AND demand the ₦250,000 WHT you should have deducted.

The penalties exceed the tax owed. Compliance isn’t optional.

WHT vs Income Tax: How It Works for Contractors

Contractors often ask: “Why are you deducting money from my payment?”

Here’s the explanation: WHT is advance payment of their income tax, not an extra tax.

How it works:

1. You deduct ₦100,000 WHT from their ₦2 million invoice

2. They receive ₦1.9 million

3. At year-end, they file returns showing ₦2 million income

4. FIRS calculates their total income tax due

5. They get credit for the ₦100,000 WHT you already paid

6. They pay the difference or get a refund

Bottom line: WHT reduces their final tax bill. You’re helping them pay taxes in installments instead of one large year-end payment.

Frequently Asked Questions

Q: Do foreign contractors need WHT deductions?

A: Yes, at higher rates (10% for most services). They also need Tax Clearance Certificates for payments above ₦5 million.

Q: What if the contractor doesn’t have a TIN?

A: Don’t pay them. Help them register for a TIN first. Payments to contractors without TINs violate tax law.

Q: Can I recover WHT if I deducted the wrong amount?

A: Yes, through FIRS amendment procedures, but it takes 3-6 months. Getting it right the first time is faster.

Q: Do I need to deduct WHT on reimbursements?

A: No. Pure reimbursements for verified business expenses don’t attract WHT. But distinguish between reimbursements and payments for services.

Q: What about contractors who are also companies?

A: Corporate contractors still get WHT deducted. Their corporate status doesn’t exempt them from withholding tax.

Q: How do I handle part-payments on large contracts?

A: Deduct WHT on each payment, not just the final payment. If you pay ₦1 million monthly on a ₦10 million contract, deduct WHT monthly.

Q: Can contractors refuse WHT deductions?

A: No. WHT deduction is your legal obligation, not their choice. Explain that they get credit for it during annual tax filing.
