Billing Invoicing

Also known as: Withholding Tax, Retained Tax

Money a payer deducts from an invoice and remits directly to a tax authority on the recipient's behalf.

Definition

Tax withholding is the practice of a payer deducting a portion of an invoice amount before payment and sending that amount directly to the tax authority instead of the supplier. The supplier receives the net amount and a withholding certificate they can use to claim the credit against their own tax liability.

Withholding rules are jurisdiction-specific. They typically apply when a foreign vendor invoices a domestic buyer, when professional services are paid above a threshold, or when a freelancer is paid in a country with a withholding regime. Common rates land in the 5-30% range depending on country and nature of work.

Withholding differs from sales tax or VAT. Sales tax is added on top of the invoice and collected from the customer; withholding is taken out of the supplier's invoice and paid to the government on the supplier's behalf.

Why It Matters

If your AR team doesn't account for withholding when sending international invoices, you'll be surprised when payments land 10-30% short and have to chase paperwork from the customer to recover the credit. For ops teams running cross-border subscription billing or professional-services invoicing, withholding handling is a regular operational task.

The biggest mistake is treating a short payment as a shortpay dispute when it's actually a legitimate withholding. Your customer is following local law. Issue a credit memo for the withholding amount, request the withholding certificate, and book the certificate as a tax asset.

Examples in Practice

A US consulting firm invoices a Brazilian client $10,000 for advisory work. Brazil's withholding rate on professional services to a foreign supplier is 15%. The client pays $8,500 and remits $1,500 to the Brazilian tax authority. The firm receives a withholding certificate from the client.

A SaaS vendor with European customers discovers their AR aging report shows hundreds of accounts running 5-10% short. Audit reveals the customers are in jurisdictions that require withholding on cross-border digital services. The fix: add a withholding clause to the contract and update the invoice template to reference it.

A freelance designer based in India invoices a US agency. India's withholding regime requires the agency to withhold a portion under the India-US tax treaty. The designer claims the foreign tax credit on their Indian return using the certificate the agency provides.

Frequently Asked Questions

What is tax withholding and how is it different from sales tax?

Tax withholding is money the payer deducts from an invoice and remits to a tax authority on the supplier's behalf. Sales tax is added on top of the invoice and collected from the customer. Withholding reduces what the supplier receives; sales tax increases what the customer pays.

When does withholding apply?

Typically for cross-border professional services, royalties, dividends, and interest payments. Many countries also withhold on payments to freelancers or contractors above a threshold. Specific rules vary widely — always check the destination country's tax regime.

What withholding rate should I expect?

Rates commonly fall between 5% and 30% depending on the country, the type of service, and whether a tax treaty exists between the supplier's and buyer's countries. Treaty rates are usually lower than statutory rates.

How do I recover the withheld amount?

You claim the withholding as a foreign tax credit on your own tax return. The withholding certificate from the payer is the document you need. Some jurisdictions also allow refund claims directly to the foreign tax authority.

What happens if my customer withholds and doesn't tell me?

Your AR report will show a partial payment. You should contact the customer, confirm it's a withholding rather than a dispute, and request the withholding certificate before treating the balance as written off.

Does AMW Commerce handle withholding on subscription invoices?

AMW Commerce supports recording withholding as a non-revenue line item on cross-border invoices so the recognized revenue stays correct and the AR is reconciled when the certificate arrives. The withholding amount is typically captured as a tax asset for the supplier to claim later.

Is withholding the same in every country?

No. Rates, thresholds, and the list of services subject to withholding vary by country. Some countries have no withholding regime; others apply different rates to royalties versus services versus dividends.

Can I gross-up the invoice to absorb the withholding?

Yes — if your customer agrees in the contract, you can increase the invoice amount so that after withholding the net payment matches your target. Be aware that gross-up effectively shifts the tax cost onto the customer, which they may push back on.
