When Your Customer Doesn't Deduct: Understanding Withholdee Liability for Withholding Tax in Tanzania

By Aakvatech Limited | Tax & Compliance Insights

---

Withholding tax (WHT) is one of those areas of Tanzanian tax law where many businesses assume the obligation lies entirely with whoever is making the payment. That assumption can be costly. If your customer pays you the full invoice amount without deducting withholding tax, you — the withholdee — are not automatically off the hook. The law creates a direct, personal tax exposure on your side of the transaction.

This article unpacks the legal framework, walks through the practical scenarios, and explains what you should do to protect yourself.

What Is Withholding Tax and Who Are the Parties?

Withholding tax is a mechanism by which the payer of a qualifying payment deducts a specified percentage of income tax at source and remits it directly to the Tanzania Revenue Authority (TRA) on behalf of the recipient.

The Income Tax Act, CAP. 332 R.E. 2019 (originally Act No. 11 of 2004) defines the two parties clearly under Section 3:

• Withholdee — a person receiving or entitled to receive a payment from which income tax is required to be withheld under Subdivision A of Division II of Part VII (i.e. sections 81–83A of the ITA)
• Withholding Agent — the person making the payment who is required by law to deduct and remit the WHT

Withholding obligations apply to a range of payments including employment income (s.81), investment returns such as dividends, interest, rent and royalties (s.82), service fees and contract payments (s.83), and payments for the supply of goods to government institutions (s.83A).

The Core Problem: What Happens When the Agent Doesn't Withhold?

The common scenario: you issue an invoice for TZS 10,000,000. Your customer — a government body or registered withholding agent — should deduct 5% WHT (TZS 500,000) and pay you TZS 9,500,000, remitting the TZS 500,000 to TRA. Instead, they pay you the full TZS 10,000,000 and remit nothing.

You have received more than you were contractually entitled to net of tax. The government has received nothing. Who is liable?

Section 84: The Joint and Several Liability Provision

Section 84 of the ITA (Statements and Payments of Tax Withheld or Treated as Withheld) is the key provision. Its operative effect, consistently applied by the Tax Revenue Appeals Board (TRAB) and the Court of Appeal, is as follows:

Where a withholding agent fails to withhold income tax from a payment, the withholdee is jointly and severally liable with the withholding agent for the payment of that tax.

"Jointly and severally" means TRA can pursue either party, or both simultaneously, for the full amount. You cannot escape the assessment simply because it was your customer's legal obligation to withhold. The liability attaches to you by operation of law.

Additionally, section 84 provides a recovery right: a withholding agent who fails to withhold but subsequently pays the tax to TRA is entitled to recover an equal amount from the withholdee. However — and this is critical — any interest or penalties imposed on the agent for their non-compliance cannot be recovered from you. That cost stays with the defaulting agent.

The Finance Act 2016 Amendment: Section 11(2)(f)

The Finance Act 2016 (Act No. 2 of 2016, s.18) amended the definition of excluded expenditure under section 11(2) of the ITA to add "withholding tax paid by a withholder" to the list of non-deductible expenses.

The practical implication: if a withholding agent pays the WHT themselves rather than deducting it from your payment, they cannot claim a tax deduction for that cost. The law's design is clear — the WHT burden was always meant to fall on you as the income earner. The agent is merely TRA's collection mechanism.

Does Paying Full Corporate Tax at Year-End Extinguish the WHT Liability?

This is one of the most frequently asked questions in practice, and the answer is nuanced.

When no WHT certificate exists (because the agent never withheld), Section 87 of the ITA means you cannot claim WHT as a credit against your corporate income tax. You pay your full corporate tax on the gross income received. TRA receives the full tax revenue.

Does this mean the WHT liability is extinguished? Not automatically, and not by statute.

Here is why:

1. The tax types are legally separate. Corporate income tax assessed under s.94 (self-assessment) and the WHT obligation under ss.81–83A are distinct instruments. TRA's audit and assessment systems treat them separately. An auditor examining your customer's WHT compliance can still raise a demand — which flows back to you — even if your corporate tax is fully paid and up to date.

2. There is no express statutory relief. The ITA contains no provision stating that full payment of corporate income tax extinguishes joint and several WHT liability. The credit mechanism in s.87 works in one direction only: WHT certificate reduces corporate tax. The reverse — corporate tax paid eliminates WHT exposure — is not in the law.

The practical argument you can make to TRA, if challenged, is this: "The income was fully included in our taxable income. Full corporate tax was paid. There is no revenue loss to TRA." This is a legitimate equitable position, and TRA auditors will often accept it. But it is a concession, not a right. You need to substantiate it with clean documentation.

What If You Have Notified the Customer in Writing?

Alerting your customer by email or letter that they are required to deduct WHT is good practice and legally significant — but it does not remove your s.84 liability.

Section 84 creates liability by operation of law. It is not conditional on whether you warned the agent or failed to do so. The statute is silent on notification as a defence.

What written notification does achieve:

• It establishes good faith and demonstrates you were not complicit in the non-deduction
• It creates a paper trail supporting your civil recovery claim against the customer
• It is a mitigating factor in TRA audit negotiations, reducing or eliminating penalties on you as the withholdee
• It strengthens your position if you need to refer the matter to TRA or pursue contractual remedies

Escalating Beyond Email: What You Should Actually Do

Email alone is insufficient. Take the following steps in order:

Step 1 — Formal written notice. Issue a formal letter on company letterhead to the customer, citing Section 84 of the Income Tax Act CAP. 332, specifying the transaction, the applicable WHT rate, the amount undeducted, and the deadline by which they must either (a) deduct from the next payment and remit to TRA, or (b) remit the WHT directly to TRA and furnish you with the certificate.

Step 2 — Contractual protection. Ensure your service contracts include an explicit WHT clause. The clause should: identify the customer as the withholding agent under the applicable ITA section; require them to deduct, remit and provide a certificate within 7 days of month-end; and include an indemnity — they bear all interest, penalties and legal costs arising from their failure to comply, and they cannot recover those costs from you (consistent with s.84).

Step 3 — Clean income tax return. File your corporate tax return including the gross income, pay full tax on it, and document clearly that no WHT certificate was received. Keep this documentation on file for at least five years.

Step 4 — Consider voluntary disclosure. If the amounts are material and no resolution is in sight, proactive disclosure to TRA generally eliminates or significantly reduces penalties. TRA's voluntary disclosure process under the Tax Administration Act CAP. 438 is available for this purpose.

The Right Accounting Treatment: Hold the WHT as a Liability

Here is where good practice and legal logic converge perfectly.

When a customer pays you the full gross amount, the WHT component is not your money. It is the government's tax revenue, misdirected because the agent failed to deduct. The correct treatment is to book the WHT component as a current liability on your balance sheet — not as income.

Journal Entries

On receipt of full gross payment (e.g. TZS 10,000,000 for a service subject to 5% WHT):

Account	Debit (TZS)	Credit (TZS)
Bank	10,000,000	—
Revenue	—	9,500,000
WHT Liability (Current)	—	500,000

When the customer presents a WHT certificate (having paid TRA):

Account	Debit (TZS)	Credit (TZS)
WHT Liability	500,000	—
WHT Credit Receivable / Tax Offset	—	500,000

You can now claim the s.87 credit on your next corporate tax return, and refund or offset the TZS 500,000 to/against the customer.

If TRA assesses you directly before the customer pays:

Account	Debit (TZS)	Credit (TZS)
WHT Liability	500,000	—
Bank (payment to TRA)	—	500,000

You then exercise your s.84 recovery right against the customer for TZS 500,000. Penalties and interest from TRA (if any) are a separate expense — do not include these in the recovery claim against the customer (s.84 does not permit recovery of penalties/interest from the withholdee).

Why This Treatment Is Correct

1. It reflects economic reality. You did not earn the WHT component — it was always TRA's money passing through your hands.
2. It preserves the s.84 recovery right. The liability account flags the amount you can recover from the customer once they settle with TRA.
3. It keeps corporate tax clean. Revenue is recognised net of WHT; your taxable income is correctly stated.
4. It demonstrates good governance. In an audit, a properly maintained WHT liability account signals compliance awareness and good faith — both mitigating factors in TRA's penalty discretion.
5. It is defensible under IFRS/IAS. Under IAS 37 and general accruals principles, a present obligation of uncertain timing that you can quantify should be recognised as a provision or liability — which is exactly what this is.

The Case Law: What the Courts Have Confirmed

Pan African Energy Tanzania Ltd v Commissioner General, TRA

Civil Appeal No. 81 of 2019 — Court of Appeal of Tanzania, 6 March 2020

The Court of Appeal, relying directly on sections 7, 81 and 84 of the ITA 2004, ruled that paying an employee or recipient the full gross amount — rather than the net after WHT — confers a taxable benefit on the recipient and is prohibited in law. The grossing-up approach was held to violate the statutory withholding framework.

Significance for withholdees: Receiving the full gross amount is not a free pass. The WHT component received by the withholdee in excess of the net amount is a taxable economic benefit, and the transaction structure does not override the s.84 liability.

Vodacom Tanzania PLC v Commissioner General, TRA

Tax Appeal No. 50 of 2018 — Tax Revenue Appeals Board, 15 October 2021

The TRAB ruled that the withholding obligation under section 82(1) of the ITA 2004 arises on actual payment — not on accrual. The Board applied the definition of "payment" under section 3 of the ITA in its ordinary sense, declining to extend the obligation to mere book entries.

Significance for withholdees: The moment a customer pays you the full gross amount, the WHT obligation crystallises immediately. There is no deferral argument. The clock starts ticking for both the agent's remittance obligation and your joint and several exposure under s.84.

Summary: Your Obligations and Protections at a Glance

Situation	Your Position
Customer pays gross, no WHT deducted	Jointly and severally liable under s.84 — TRA can assess you directly
You pay full corporate tax at year-end	Strong equitable argument that no revenue is lost, but not a statutory right of relief
You notified the customer in writing	Mitigates penalties and supports recovery claim, but does not extinguish s.84 liability
Customer pays TRA and gives you a certificate	You claim s.87 credit, release the liability, recover the amount from customer
TRA assesses you directly	Pay from the liability reserve, then exercise s.84 recovery right against customer
Customer refuses to cooperate	Formal legal action; the indemnity clause in your contract and your written notices are your primary evidence

Final Thoughts

The Tanzanian withholding tax framework places real, enforceable obligations on withholdees — not just withholding agents. Section 84 of the Income Tax Act is unambiguous on joint and several liability, and both the Court of Appeal and the TRAB have reinforced this through decided cases.

The good news is that the risk is manageable with the right systems:

• Notify customers formally at the start of every engagement
• Include WHT clauses and indemnities in your contracts
• Hold the WHT component as a liability — never treat it as income
• File your corporate tax returns correctly so TRA has full visibility of the gross income
• Request certificates proactively — do not wait for the customer to volunteer them
