How to Include Facebook and Google Advertising Expenses as Deductible Business Costs in Vietnam
Advertising expenses on platforms like Facebook and Google can be considered deductible business costs under Vietnam’s Corporate Income Tax (CIT) law. Proper accounting of these expenses can reduce the taxable income of a company. However, to qualify, businesses must meet specific documentation and compliance requirements.

Conditions for Advertising Expenses to Be Deductible
1. Valid Invoices and Documentation
Businesses must obtain valid invoices or payment documents from Facebook or Google. If services are provided by foreign entities, invoices may need to be translated and certified.
2. Appropriate Payment Methods
Payments should be made through the company’s bank account. Cash payments or payments through personal accounts are not acceptable.
3. Direct Relation to Business Activities
The advertising expenses must directly relate to the company’s business operations. Expenses not clearly linked to business activities may be disallowed.
4. Clear Service Contracts
There should be a written contract detailing the advertising services, including duration, content, costs, payment methods, and obligations of both parties.
5. Compliance with Legal Limits
According to the Law on Corporate Income Tax No. 14/2008/QH12, advertising expenses are not subject to a cap if the company is enjoying tax incentives. However, expenses should still be reasonable and well-documented.

Additional Considerations for Validating Advertising Expenses
1. Consistency in Company Information
The name and tax code on invoices must match the company’s registered information. Using personal accounts for payments can lead to disqualification of the expense.
2. Timing of Expense Recognition
Expenses should be recorded in the accounting period in which they occur. Misalignment can result in non-deductibility.
3. Actual Business Activities
Advertising should promote products or services that the company is actively offering. Promoting inactive or non-existent products can raise concerns.
4. Legitimate Service Providers
Engaging with intermediaries lacking legal status or proper documentation can jeopardize the deductibility of expenses.
Steps to Account for Facebook and Google Advertising Expenses
1. Prepare Contracts and Supporting Documents
Establish contracts with Facebook, Google, or their authorized partners. Maintain records of communications, advertising content, and detailed cost breakdowns.
2. Obtain Proper Invoices
If using local agencies, ensure they provide valid VAT invoices. For direct payments to Facebook or Google, retain electronic invoices and translate them if necessary.
3. Record in Appropriate Accounting Accounts
Allocate advertising expenses to account 641 (selling expenses) or other suitable accounts.
4. Maintain Comprehensive Records for Tax Audits
Store all related documents, including invoices, bank statements, contracts, acceptance reports, and confirmation emails, for at least 10 years.
5. Monitor Expenses Using Accounting Software
Regularly input and reconcile advertising expenses in accounting software to ensure accuracy and compliance.
Common Mistakes Leading to Disallowed Expenses
1. Using Cash or Personal Accounts for Payments
Such payments are not recognized for tax deduction purposes.
2. Lack of Proper Documentation
Missing invoices, bank statements, or contracts can result in disqualification.
3. Unrelated Advertising Content
Advertising not directly linked to business operations may be deemed unnecessary.
4. Invalid Contracts
Contracts lacking signatures, clear terms, or mutual agreement can be problematic.
5. Exceeding Reasonable Expense Limits
Even without a formal cap, excessive advertising expenses without justification can be scrutinized.
