Withholding Tax In Nigeria: Who Deducts, When, And The Exemption For Small Companies.

Withholding Tax (WHT) is a tax collected at source on transactions such as goods, services, rent, dividends, royalties, and interest. The payer deducts a statutory percentage from the payee’s invoice and remits it directly to the tax authority. This payment acts as an advance credit toward the payee’s total income tax liability or serves as a final tax for non-residents. Ultimately, WHT secures immediate revenue for the government, curbs tax evasion, and brings unregistered operators into the tax net.

For legal counsel, corporate accountants, and business owners, navigating the contemporary framework requires mastering three core dimensions: who is legally obligated to deduct, precisely when that deduction must trigger, and how small companies are shielded from the tax drag.

Section 50(4) of the NTA 2025 made reference to the Deduction of Tax at Source Regulation. This regulation sets out the provisions governing WHT, and this article refers to it as the main provision for WHT.

1. The Burden of Collection: Who Deducts?

The obligation to withhold tax at source applies broadly to:

• All corporate bodies and unincorporated entities (excluding individuals).
• Government entities, including federal, state, and local Ministries, Departments, and Agencies (MDAs), alongside public authorities and statutory bodies.
• Tax-exempt institutions—including non-governmental organisations (NGOs), charities, and registered cooperative societies. Even if an entity’s core operations are exempt from income tax, it remains legally bound to deduct and remit WHT when making eligible payments to third-party contractors or suppliers.

Crucially, natural persons acting strictly in their private, personal capacities are completely excluded from the obligation to act as WHT agents.

2. When to Deduct?

The law now splits transactions into two explicit tracks to prevent artificial cash-flow choking:

• Under Regulation 3(1), for ordinary, arm’s-length commercial dealings, the obligation to deduct WHT arises strictly at the earlier of when payment is actually made or when the amount due is otherwise financially settled. Receiving a vendor invoice or recording an accrued liability in your general ledger no longer creates a premature tax debt. WHT is now strictly tied to liquid settlement.
• To curb aggressive tax planning and intra-group manoeuvres, transactions between connected entities face a tighter extraction window. Under Regulation 3(2), WHT on related-party transactions crystallises at the earlier of when the liability is formally recognised in the accounts or when payment is executed.

3. Statutory Remittance Timelines

Once a deduction has been made, the statutory countdown to remit those funds to the tax authorities remains rigid:

• Federal Remittance to Nigeria Revenue Service: Must be remitted on or before the 21st day of the month following deduction.
• State Remittance (State Internal Revenue Services): Must be remitted on or before the 30th day of the month following deduction.

4. Exemptions for Small Companies

The intersection of the 2024 Regulations and the Nigeria Tax Act 2025 creates a powerful dual-shield designed to keep cash inside low-margin, small-scale operations. Under section 147 of the NTAA, 2025, the legal definition of a small company has been expanded to encompass businesses with an annual gross turnover of ₦100,000,00 or less and total fixed assets not exceeding ₦250 million.

The framework approaches small company insulation from two distinct angles:

1. Exemption from deducting WHT (As a Buyer)

Per Regulation 2(2), a small company is entirely absolved from the administrative nightmare of calculating, withholding, and filing tax on the vendors it hires. However, to enjoy this immunity from acting as a collection agent, the small business must meet two strict concurrent criteria:

• The Transaction Cap: The cumulative value of the transactions with that specific vendor must not exceed ₦2,000,000 within a single calendar month. If a single invoice or a series of monthly transactions from one supplier breaches this ₦2 million ceiling, the small company must fulfil standard compliance and deduct the tax.
• The TIN Mandate: The supplier being paid must possess and present a valid Taxpayer Identification Number (TIN).

When a small company operates as the vendor or service provider, its immediate liquidity is protected by Regulation 10(1). Large corporate clients are instructed not to deduct WHT from payments due to a small company, provided the transaction remains below the ₦2 million monthly cap and the small company supplies its valid TIN.

This matches the 0% Corporate Income Tax rate guaranteed to small enterprises under Chapter 2 of the Nigeria Tax Act 2025, ensuring micro-businesses do not have their working capital trapped at source.

Exemption of Professional Services firms from the definition of a small business.

Business owners must look closely at Regulation 9 and the interpretation section of the NTAA 2025, as the provisions do not consider any business providing professional services as a small company. The small company exemptions explicitly exclude professional, technical, or consultancy services. If a small business operates as a law firm, accounting practice, architectural consultancy, or engineering agency, it cannot utilise these revenue exemptions. Professional fees are subject to standard WHT deductions, ensuring institutional accountability across licensed professional fields.

5. Risks of Non-Compliance: Penalties Under the Framework

Non-compliance with the WHT provisions may expose entities to financial penalties. For corporate managers, finance teams, and compliance officers, understanding the statutory liabilities attached to tax obligations is no longer optional; it is a critical element of risk management. The NTAA provides for penalties for non-collection and non-remittance of WHT. The legislation penalises a failure to collect differently from a failure to remit, attaching significantly different penalties, interest obligations, and criminal risks to each offence.

The Statutory Penalty Framework

The statutory framework under Sections 105, 106, 107, 114, and 133 sets clear administrative fines, interest rates, and criminal liabilities across various compliance failures:

1. Section 105 — Failure to Collect or Deduct Tax
   1. Offence: Failing to withhold or collect tax at source (e.g., Withholding Tax or Value Added Tax) when required by law.
   2. Penalty: An administrative penalty equal to 40% of the tax amount not collected or deducted, in addition to paying the underlying principal tax.
2. Section 106 — Failure to Make Attribution
   1. Offence: Failing to properly attribute income or notify the relevant tax authority regarding statutory tax obligations.
   2. Penalty: A fixed administrative penalty of ₦1,000,000.
3. Section 107 — Failure to Remit Tax
   1. Offence: Deducting or collecting tax from a third party but failing to remit those funds to the tax authority within the statutory timeframe (typically by the 21st day of the following month).
   2. Penalty:
      i. Recovery of the full principal tax amount.
      ii. A 10% per annum penalty on the unremitted amount.
      iii. Interest accrued at the prevailing Central Bank of Nigeria (CBN) Monetary Policy Rate (MPR).
      iv. Criminal liability upon conviction, carrying a fine, imprisonment for up to 3 years, or both.
4. The No-TIN Penalty: Under Regulation 1(c), if a deducting agent conducts an eligible transaction with any vendor who cannot provide a valid TIN, the standard WHT rate is automatically doubled (capping at a maximum of 20%) on all trading and non-passive income streams.
