WHT Explained Simply: What to Do When Tax Is Deducted From Your Payment

What is WHT?

WHT means Withholding Tax.

In simple terms, it is tax deducted at source when certain payments are made. Instead of the full amount being paid to the supplier, vendor, consultant, contractor, or service provider, part of the payment is deducted and remitted to the tax authority.

This is why a business owner may issue an invoice for one amount but receive a lower amount in the bank account.

For example, your business may invoice a company for a service. The company may deduct withholding tax and pay you the balance.

Many business owners get confused at this point. Some think the client underpaid them. Some think it is a bank charge. Some ignore the deduction completely. Some do not ask for the credit note or evidence. Some do not record the gross invoice value properly, and only record the amount received.

That can create problems later. WHT should not be treated casually. It is part of your business tax records.

Why tax may be deducted from your payment

Withholding tax is common in transactions involving companies, contractors, consultants, service providers, landlords, suppliers, and vendors. The client or payer may be required to deduct tax before paying you. This does not always mean something is wrong. It may simply mean the payer is applying tax deduction rules to the transaction.

The problem begins when the business owner does not understand the deduction or fails to keep evidence.

If tax is deducted from your payment, you should be able to answer:

• Who deducted the tax?
• What invoice was affected?
• What was the gross invoice amount?
• How much was deducted?
• How much was paid to you?
• What type of transaction was it?
• Was your Tax ID provided?
• Did you receive a credit note or deduction evidence?
• Was the deduction recorded in your books?

These questions matter because WHT deductions can affect your tax records. If you do not keep the evidence, it may become difficult to prove that tax was already deducted from your payment.

WHT is not the same as a bank charge

One common mistake is treating WHT as if it is a bank charge or random loss. It is not. A bank charge is a fee charged by the bank. Withholding tax is tax deducted from the payment at source. That means your business transaction still has a gross value, even though you received a net amount.

For example:

• Invoice value: ₦500,000
• WHT deducted: ₦25,000
• Amount received: ₦475,000

If you only record ₦475,000 as sales, your records may not tell the full story. A cleaner record would show the gross invoice amount, WHT deducted, net amount received, client name, invoice number, date of payment, and evidence of deduction.

This makes your business records easier to understand.

Why Tax ID matters

Your Tax Identification Number matters because many tax processes now depend on proper identification. In the Rev360 WHT filing process, the system validates Tax IDs and displays a match status to show whether each Tax ID exists in the tax administration system.

The Rev360 manual also notes that WHT rates can vary depending on the availability of a Tax ID, and where a beneficiary does not provide a Tax ID, a 20 percent WHT rate applies.

This means business owners should not treat Tax ID as an optional detail. If clients, vendors, or beneficiaries do not provide proper tax identification details, filing can become more complicated.

For business owners receiving payment, having your Tax ID ready can help your client process the transaction properly. For business owners making payments, collecting vendor Tax IDs can help you prepare better WHT records. Tax ID is part of the new business foundation. It helps connect transactions to the correct taxpayer.

What to do when WHT is deducted

When a client deducts withholding tax from your payment, do not panic. But do not ignore it either. Take these steps.

1. Confirm the deduction

Check the invoice amount, payment amount, and deduction amount. Make sure the difference is actually WHT and not a bank charge, short payment, refund, discount, or payment error.

2. Ask for deduction evidence

Request the WHT credit note, deduction certificate, or any official evidence showing that tax was deducted and remitted. The exact document name may vary depending on the process, but the principle is the same: do not rely only on verbal confirmation.

3. Record the gross invoice value

Your records should show the full value of the invoice before deduction. This helps you avoid understating sales.

4. Record the WHT deducted

Create a column or note for the deducted tax amount. This helps you track what was deducted and by whom.

5. Record the net amount received

Your bank statement will show the actual amount received. Your records should connect that amount to the gross invoice and the deduction.

6. Store the evidence safely

Keep the evidence in your business records, preferably in a folder linked to the client, invoice, or accounting period.

7. Get help if the deduction does not make sense

If the rate, transaction type, or deduction amount looks wrong, ask before accepting it silently.

What records you should keep

WHT records should be simple, but complete. At minimum, keep:

• Client or payer name
• Invoice number
• Invoice date
• Gross invoice amount
• Amount deducted as WHT
• Net amount received
• Date payment was received
• Transaction description
• Tax ID used
• Credit note or deduction evidence
• Any related email or official communication

The reason this matters is simple. If your tax records are ever reviewed, you need to show what happened. You should be able to explain: this was the invoice amount, this was the amount deducted, this was the amount received, and this is the evidence.

That is much stronger than relying on memory. Your business should rely on records.

What Rev360 expects for WHT filing

The Rev360 WHT filing process shows that WHT filing is structured and data-driven. The manual explains that the WHT module enables taxpayers to report tax deducted at source using a structured Excel template. It supports bulk transaction uploads, automated tax computation, and validation of Tax Identification Numbers.

In practical terms, the filing process may involve:

1. Logging into Rev360
2. Navigating to Self Tax Filing
3. Selecting File Taxes
4. Choosing Withholding Tax
5. Downloading the WHT template
6. Opening the Excel worksheet
7. Entering required transaction details
8. Uploading the completed template
9. Selecting the applicable currency
10. Allowing the system to compute the WHT amount
11. Reviewing the uploaded schedule
12. Checking Tax ID validation status
13. Reviewing total transaction amount and total WHT amount
14. Submitting the schedule

For business owners, this means WHT filing is not just about paying a deduction. It is about preparing a proper schedule. If your transaction records are not complete, the template can become difficult to fill correctly. If Tax IDs are wrong or missing, validation issues may appear. If figures are wrong, the computed WHT amount can be wrong.

Common WHT mistakes to avoid

Here are common mistakes business owners should avoid.

1. Recording only the amount received

If WHT was deducted, record the full invoice amount, deduction amount, and net amount received.

2. Not requesting evidence

If tax was deducted from your payment, request proof. Do not rely only on bank alerts.

3. Treating WHT as a loss

WHT is not just missing money. It is tax deducted at source and should be tracked properly.

4. Not providing your Tax ID

Clients may need your Tax ID to process deductions correctly. Keep it accessible.

5. Not collecting vendor Tax IDs

If your business deducts WHT from vendors or suppliers, collect their correct Tax IDs where required.

6. Mixing business and personal accounts

If payments enter personal accounts randomly, it becomes harder to track deductions properly.

7. Ignoring transaction classification

Different transactions may be treated differently. Do not assume one rate or treatment applies to everything.

8. Submitting without reviewing

Before submitting a WHT schedule, review names, Tax IDs, transaction amounts, WHT amounts, and totals.

When to get help

You should consider getting help if WHT is appearing in your business transactions and you are not sure what to do. This is especially important if:

• Companies deduct tax from your invoices
• You work with corporate clients
• You pay consultants, vendors, suppliers, landlords, or contractors
• You do not know whether to deduct WHT from a payment
• You do not know the correct rate
• You do not have Tax IDs for vendors or beneficiaries
• You do not know how to record WHT deductions
• You do not know how to request a credit note
• You want to use Rev360 but do not understand the WHT template
• You have many transactions to upload
• Your figures do not match the payment received
• You are preparing for tax filing and need your records reviewed

Getting help does not mean your business is not serious. It means you are trying to avoid wrong records, wrong deductions, and avoidable filing errors. A business that handles WHT properly will have cleaner records and better tax clarity.

Simple WHT checklist

WHT is one of those tax areas business owners often notice only after money enters the account. But by then, part of the transaction may already have been deducted. The right response is not panic. The right response is structure. Keep the invoice, record the gross amount, record the deduction, record the amount received, request evidence, keep your Tax ID ready, and review your records before filing. That is how withholding tax becomes easier to understand and manage.
