Withholding Tax on Contracts, Salaries and Supplies Around the World

Withholding tax is an important part of the tax system in many countries. It generally means that the person or business making a payment deducts a specified amount of tax before paying the remaining amount to the recipient. The deducted amount is then paid to the relevant tax authority.

The rules are not the same everywhere. Some countries apply withholding tax extensively to domestic payments, while others primarily use it for particular types of income or cross-border transactions. Rates can also differ according to the nature of the payment, the status of the recipient, and whether a tax treaty applies.

International tax data shows substantial differences between jurisdictions. The OECD’s 2026 analysis covers 146 jurisdictions and notes that withholding-tax rates vary significantly according to both jurisdiction and type of income.

For businesses operating internationally, understanding these differences is important because an incorrect withholding can create additional tax, penalties, interest and compliance problems.

What Is Withholding Tax?

Withholding tax is a tax collected at source. Instead of allowing the recipient to receive the full gross payment and subsequently pay all applicable tax, the payer deducts the required amount and sends it to the government.

For example, if a business has to pay a contractor $10,000 and the applicable withholding rate is 5%, the business may deduct $500 and pay $9,500 to the contractor while remitting $500 to the tax authority.

The exact treatment depends on local legislation.

Withholding tax may apply to payments such as:

• Salaries and wages
• Professional services
• Contracts
• Construction services
• Technical services
• Supplies or sales of goods in some jurisdictions
• Dividends
• Interest
• Royalties
• Rent
• Commissions

It is important not to assume that every country applies withholding tax to all of these categories.

Withholding Tax on Salaries

Salary withholding is one of the most familiar forms of tax withholding.

In many countries, employers are required to deduct income tax from employees’ salaries before making payment. The employer then submits the deducted amount to the relevant tax authority and normally provides payroll reporting.

Salary withholding may depend on:

• Employee income
• Tax residency
• Tax brackets
• Allowances
• Tax credits
• Social-security requirements
• Employment status
• Local payroll legislation

Therefore, salary withholding should not be confused with a single worldwide tax rate.

An employee earning the same gross salary in two different countries may have very different withholding obligations because each country’s tax system operates differently.

Withholding Tax on Contracts

Contract payments can receive different treatment depending on the country and the nature of the contract.

Some jurisdictions impose withholding on payments for construction, procurement, government contracts, professional work, technical services or other specified contracts.

For example, Pakistan applies withholding tax to several resident transactions, including sales of goods, execution of contracts and rendering of services. Current Pakistani rules include different rates depending on the category of payment and recipient.

Businesses therefore need to determine:

1. What type of contract is being paid?
2. Who is receiving the payment?
3. Is the recipient resident or non-resident?
4. Is the recipient an individual, partnership or company?
5. Is the payment subject to a specific withholding provision?
6. Does a tax treaty affect the applicable rate?
7. What documentation is required?

These questions can significantly affect the final withholding amount.

Withholding Tax on Supplies and Goods

Withholding tax on supplies is not treated uniformly worldwide.

Some countries impose withholding requirements on certain purchases of goods or supplies, particularly where the buyer is a designated withholding agent. Other countries may not impose ordinary withholding tax on domestic purchases of goods.

The distinction between supplies, services and contracts is therefore important.

A business should not automatically apply a withholding rate simply because it is making a payment to a supplier. The applicable legislation must first be reviewed.

For example, Pakistan’s current corporate withholding rules include WHT on sales of goods, with different rates depending on the type of recipient.

Withholding Tax on Services

Services can be particularly important in international business.

A company may purchase:

• Accounting services
• Legal services
• Consulting
• Engineering
• Software development
• IT services
• Marketing
• Advertising
• Technical services
• Management services

The tax treatment may depend on whether the service provider is resident or non-resident and where the service is considered to arise or be performed.

International tax treaties can also change the result. The OECD notes that treaty-based withholding rates can be substantially lower than domestic statutory rates, particularly for cross-border payments.

Withholding Tax and International Tax Treaties

Tax treaties are extremely important when a business makes cross-border payments.

A domestic law may establish one withholding rate, while a bilateral tax treaty between the two countries may provide a reduced rate or, in certain circumstances, no withholding tax.

The OECD reports that the global network of bilateral tax treaties has expanded significantly and that treaty provisions can substantially reduce withholding-tax burdens compared with domestic rates.

Before applying withholding tax to an international payment, businesses should therefore check:

• The domestic tax law
• The recipient’s tax residence
• The applicable tax treaty
• The type of income
• Permanent-establishment rules
• Beneficial ownership requirements where relevant
• Tax-residency documentation
• Any required certificates or forms

Why Withholding Tax Rates Differ Around the World

There is no single worldwide withholding-tax rate.

Countries establish their own tax rules based on their economic policies, tax structures and international agreements.

For example, the OECD’s 2026 statistics show average statutory cross-border withholding rates of 12.2% for dividends, 12.8% for interest and 14.5% for royalties across 146 jurisdictions. These figures demonstrate why international withholding tax cannot be reduced to one universal percentage.

Rates can also differ within the same country according to:

• Payment type
• Resident versus non-resident recipient
• Individual versus company
• Industry
• Taxpayer registration
• Treaty eligibility
• Government exemptions
• Special tax regimes

Withholding Tax Compliance for Businesses

Businesses responsible for withholding tax should establish a proper process for every applicable payment.

A practical process includes:

Step 1: Identify the payment

Determine whether the payment relates to salary, goods, services, rent, interest, royalty, contract work or another category.

Step 2: Identify the recipient

Confirm whether the recipient is an individual, company, partnership, resident or non-resident.

Step 3: Check the applicable law

Review the relevant tax rules and withholding provisions.

Step 4: Check tax treaties

For international payments, determine whether a tax treaty applies.

Step 5: Calculate the withholding

Apply the legally applicable rate to the appropriate tax base.

Step 6: Deduct and pay

Deduct the required amount from the payment and remit it to the tax authority within the required deadline.

Step 7: Maintain records

Keep invoices, contracts, tax certificates, residency documents and payment records.

Step 8: Report the withholding

Complete the relevant tax returns, statements or withholding certificates required by the jurisdiction.

Why Professional Accounting Support Matters

International withholding tax can become complicated when a business works with customers, employees, contractors and suppliers in different countries.

Professional accounting and tax support can help businesses:

• Identify applicable withholding requirements
• Review contracts and invoices
• Calculate deductions
• Maintain supplier records
• Reconcile tax payments
• Prepare withholding reports
• Review tax documentation
• Monitor international payments
• Consider applicable tax treaties
• Reduce avoidable compliance errors

A professional review is particularly valuable for businesses making regular cross-border payments.

Withholding Tax Around the World: Important Reminder

Withholding tax should always be checked according to the specific country, payment type, taxpayer status and applicable tax year.

International tax databases demonstrate that withholding rules vary considerably among jurisdictions, and specialist sources such as PwC and Deloitte maintain country-by-country tax information that is updated as legislation changes.

Therefore, a worldwide article should be used as a general educational guide rather than as a substitute for country-specific tax advice.

Conclusion

Withholding tax is an important mechanism used by governments to collect tax from payments at source. It can apply to salaries, contracts, services, supplies and various forms of investment income, depending on the country’s legislation.

For international businesses, the most important point is that there is no single global withholding-tax rate. The correct treatment depends on the jurisdiction, nature of payment, recipient’s tax status and, for cross-border transactions, applicable tax treaties.

Businesses should review withholding requirements before making significant payments and maintain appropriate documentation to demonstrate why a particular rate was applied.
