Withholding tax is income tax that the payer deducts from a payment at source and sends straight to the tax authority, rather than paying the recipient the full amount. The person or business being paid receives the net figure, and the withheld portion counts as tax they have already paid. It is a way for governments to collect tax as income is earned, instead of waiting for a return at year end.
Most people meet withholding tax through payroll, where an employer deducts tax from wages. But it matters just as much in accounts receivable, because a customer can withhold tax from an invoice payment too. When that happens, the cash that lands in your account is less than the invoice total, and the gap is not a short payment or a dispute. It is tax, and it changes how you reconcile and chase the balance.
Tax taken at source.The payer deducts it from the payment and remits it to the tax authority on your behalf.
You receive less than the invoice.On a withheld invoice the cash that arrives is the net figure, not the full amount billed.
It is a credit, not a loss.The withheld tax offsets your own tax bill once you have a valid certificate to claim it.
Withholding tax works by shifting the job of collecting tax from the recipient to the payer. Instead of you earning income, paying it into your account, and settling tax later, the payer removes the tax first and passes it to the authority directly. You then claim that amount against the tax you owe, so you are not taxed twice on the same income.
The classic case is employment: an employer withholds tax from each pay run under a system like PAYE in the UK or federal income tax withholding in the US. The same mechanism reaches business income. A customer paying for services, interest, royalties, or dividends may be legally required to withhold a set percentage and remit it, especially across borders. For an accounts receivable team, this is the version that matters, because it lands on your invoices and your bank reconciliation.
When a customer withholds tax from an invoice, they pay you the invoice amount minus the withheld percentage, and the invoice is still considered settled in full. This is the part that trips up collections. Your books show a 10,000 invoice, the bank shows 9,000 arriving, and an automated chase might fire for the missing 1,000 as if the customer underpaid. They did not. The 1,000 went to the tax authority, and chasing it damages an otherwise good relationship.
This is most common in cross-border B2B, where the buyer's country requires tax to be withheld on payments to overseas suppliers, and in sectors like construction, professional services, and licensing. The withheld amount is not yours to chase or write off. It is a tax credit you reclaim, provided the customer gives you a withholding certificate as proof. Treating it as a normal short payment is the single biggest mistake teams make here.
It also helps to know who is responsible for what. The duty splits cleanly between the two sides of the invoice, and a withheld payment only turns into a reconciliation puzzle when one side is unclear on its role.
| Responsibility | Customer (the payer) | You (the supplier) |
|---|---|---|
| Core duty | Withhold the correct amount and remit it on time. | Invoice the gross amount and expect the net receipt. |
| Paperwork | Issue a withholding certificate as proof of tax paid. | Obtain and keep that certificate to claim the credit. |
| If it goes wrong | The liability for under-withholding sits with them. | Without the certificate, the tax becomes a real cost. |
When both sides understand their role, a withheld invoice is routine. When they do not, it turns into a reconciliation puzzle and an awkward chasing email over money that was never missing.
Multiply the gross invoice amount by the withholding rate to get the tax withheld, then subtract it to find the net cash you will actually receive. The calculator below works it both ways, so you can see the net payment and the credit you will be able to claim back.
Rates vary widely by country, income type and tax treaty. Defaults show a 10% example. General information, not tax advice.
So on a 10,000 invoice with 10% withholding, you receive 9,000 in cash and hold a 1,000 tax credit. The full 10,000 is still recorded as revenue, and the invoice is paid in full. Recording this correctly in your Xero ledger keeps your net credit sales and your tax accounts accurate, rather than leaving a phantom balance that looks like an underpayment.
There is no single withholding tax rate; it depends on the country, the type of income, and whether a tax treaty applies between the two parties. Rates commonly range from around 5% to 30% on cross-border payments, with treaties often reducing the headline rate substantially. Dividends, interest, and royalties each tend to carry their own rate, and a service fee paid to a foreign contractor may be treated differently again.
The practical point for an AR team is that you do not need to memorise rate tables. You need to know which of your customers are likely to withhold, capture the rate they apply, and make sure you collect the supporting certificate. The exact figure comes from the customer's jurisdiction and any treaty in force, and it can change year to year, so treat published rates as a starting point and confirm the current position for material payments.
The cleanest approach is a simple three-step split that keeps revenue, receivables and the tax credit all in the right place. Done this way, your books never show a phantom balance that looks like an underpayment.
Book the full invoice amount as income, exactly as you would for any sale, so your revenue stays correct.
Code the withheld portion to a withholding tax account as a prepayment or asset you can later reclaim.
Split the receipt into cash received plus the withholding line, and the receivable closes out in full.
In Xero or QuickBooks this usually means splitting the receipt into the cash received plus a line coded to a withholding tax account.
Two habits then save real pain. First, flag invoices where withholding is expected before they go out, so the eventual short receipt is anticipated rather than chased. Second, file the withholding certificate the moment the customer sends it, because without that proof you cannot claim the credit and the tax becomes a genuine cost. Clean records here protect both your cash position and your view of which customers actually pay on time, which is exactly what reliable invoicing and good reconciliation are for.
One last distinction worth holding onto: withholding tax is not the same as sales tax, VAT, or GST. Those are added on top of an invoice and increase what the customer pays you. Withholding tax is deducted from the invoice and reduces what reaches your account. An invoice can carry both at once, with VAT raising the total billed and withholding then taken from the payment, which is precisely why a careful split at the point of receipt is what keeps the ledger honest.
