Value Added Tax (VAT) affects most buying and selling operations within a facility, starting from pricing products and issuing invoices, through recording sales and purchase taxes, and ending with submitting the return and settling the net tax due. An error in classifying a commodity, incorrectly applying a discount, or inaccurately entering a purchase invoice can lead to discrepancies between records, reports, and tax liabilities.

Tax management is not limited to simply adding 15% to the customer's invoice; it requires understanding the difference between output and input tax, keeping the correct documents and invoices, monitoring registration thresholds, submitting returns in designated periods, and linking sales and purchases to an organized accounting system.

This guide reviews the concept of VAT in Saudi Arabia, its importance and implications for companies and individuals, the mechanism for registration, calculation, issuing invoices, and submitting returns, in addition to the conditions and duration of VAT refunds, and how accounting software can reduce errors and facilitate the tracking of tax obligations.

What is Value Added Tax (VAT)?

VAT is an indirect tax applied to the supply and import of most goods and services, with some transactions being exempt and others subject to a zero-rate according to the rules and regulations governing them.

The tax is collected across different stages of the supply chain, but the final consumer usually bears its cost. As for the registered facility, it collects tax from its sales, then deducts the eligible input tax incurred on its purchases, and pays the result to the Zakat, Tax and Customs Authority (ZATCA), or requests a refund of the credit balance when requirements are met. The Authority clarifies that VAT is an indirect tax imposed on goods and services bought and sold by businesses, with some exceptions.

The tax cycle revolves around three main parties:

• The Supplier: The facility that provides the good or service and collects the tax.
• The Buyer: The facility or person who pays the value of the good or service and the applicable tax.
• The Zakat, Tax and Customs Authority (ZATCA): The entity responsible for regulating registration, returns, payment, refunds, and oversight.

How Does VAT Work?

The VAT mechanism relies on calculating the tax collected from sales, then subtracting the deductible tax the facility paid on its purchases related to its taxable activity.

The tax resulting from sales is called Output Tax, while the tax the facility incurred on its purchases is known as Input Tax.

The final tax due is determined by the following formula:

Net VAT = Output Tax − Deductible Input Tax

When the output tax exceeds the eligible input tax, the facility pays the difference due. However, if the eligible input tax is greater than the output tax, a credit balance may result, which can be carried forward or claimed as a refund according to regulations.

Simplified Example

Suppose a company bought goods worth 100,000 SAR before tax, then sold them for 150,000 SAR before tax.

Description	Value Before Tax	15% Tax
Purchases	100,000 SAR	15,000 SAR
Sales	150,000 SAR	22,500 SAR

Therefore, the net tax payable would be:

22,500 − 15,000 = 7,500 SAR

This means the facility does not remit the entire tax collected from customers on its sales; instead, it deducts the eligible input tax and pays only the final result.

The Importance of VAT

The importance of VAT lies in providing a regulated public resource, helping to document transactions, increasing the transparency of buying and selling operations, and prompting businesses to rely on invoices and accounting records in a more organized and accurate manner.

Among its most prominent economic and regulatory impacts are:

• Diversifying public revenue sources.
• Enhancing the documentation of sales and purchase transactions.
• Raising the level of reliance on formal invoices.
• Facilitating the tracking of operations and transactions.
• Supporting accounting and tax compliance.
• Motivating businesses to organize their accounts and inventory.
• Reducing undocumented transactions.
• Providing information that aids in economic oversight and analysis.
• Supporting fairness among businesses that adhere to market requirements.

For companies, the importance of the tax highlights the necessity to distinguish between the facility’s revenues and the tax amounts it collects on behalf of the Authority. The presence of tax amounts in the bank account does not make them freely spendable profits; rather, they represent a potential liability that must be tracked until the time of filing and payment.

The Impact of VAT on Companies

The impact of VAT is not limited to the invoice alone, but extends to pricing, liquidity, sales and purchase flow, contracts, inventory, and financial reports.

Impact on Prices

A business must clearly determine whether the prices offered to customers include or exclude the tax, clarifying this at the time of sale. The absence of this specification could cause a dispute upon payment or lead the business to absorb a portion of the tax without prior calculation.

Impact on Cash Flows

A business might receive sales tax from the customer before the time it must remit it to the Authority, but this amount does not represent freely available liquidity. Conversely, it might pay tax on its purchases before collecting the sales value from customers, especially in credit sales.

Impact on Contracts

Contracts should clarify whether the agreed-upon value includes VAT or if the tax will be added to it, in addition to determining how to handle changes, advance payments, and interim invoices.

Impact on Discounts and Returns

Discounts and returns reflect on the tax base and the tax amount; therefore, they must be documented using appropriate documents and notices instead of making unstructured modifications to the original invoice.

Impact on Accounting

A business needs to separate the accounts for output tax, input tax, adjustments, and the tax due, and reconcile the system balances with the data to be submitted in the return before approving it.

Impact on Choosing Suppliers

A correct invoice from the supplier is an important element in supporting the claim for input tax when deduction conditions are met, which is why the accuracy of the supplier's data and their issued invoices becomes more critical in the procurement cycle.

VAT in Saudi Arabia

VAT came into effect in the Kingdom with a standard rate of 5% on January 1, 2018, then the standard rate was increased to 15% starting July 1, 2020. The 15% rate is the standard rate on goods and services subject to it, with some transactions being zero-rated or exempt based on their regulatory classification.

It is incorrect to assume that every sales transaction is directly subject to the standard rate; the classification depends on the type of good or service, the nature of the supply, its location, and the status of the customer.

Classification	General Treatment
Supplies subject to the standard rate	Subject to a 15% tax
Zero-rated supplies	The tax rate is 0%, while the supply remains taxable
Exempt supplies	No tax is imposed on them, and the rules for deducting related input tax vary
Out-of-scope supplies	Do not fall within the scope of tax depending on the nature of the transaction

It is best to have an accountant or tax advisor review cases that are difficult to classify, especially activities that combine taxable and exempt supplies, or local and international transactions.

Who is Required to Register for VAT?

Registration becomes mandatory for a person conducting an economic activity when their annual taxable supplies exceed the mandatory registration threshold set at 375,000 SAR.

Voluntary registration is available for resident persons whose annual taxable supplies or expenses exceed the amount of 187,500 SAR, without reaching the mandatory registration threshold. ZATCA clarifies that registration becomes mandatory for individuals when annual revenues exceed 375,000 SAR, while it is optional when they fall between 187,500 and 375,000 SAR.

Value of Annual Supplies	General Registration Status
More than 375,000 SAR	Registration is mandatory
More than 187,500 up to 375,000 SAR	Registration is optional
187,500 SAR or less	Optional registration is generally not available based on supplies alone

Supplies must be calculated according to the periods and guidelines stipulated in the regulations, not according to the facility's profits or the balance in its bank account; the registration threshold is tied to taxable supplies, not net profit.

How to Register for VAT

VAT registration is done electronically through the Zakat, Tax and Customs Authority portal.

The main procedures consist of:

1. Logging into the beneficiary's account on the Authority's portal.
2. Opening the General Services section.
3. Selecting the VAT registration service.
4. Completing the registration form.
5. Entering the activity and supplies information.
6. Adding contact and address details.
7. Uploading required documents if needed.
8. Reviewing the data, then submitting the request.
9. Receiving the notification and registration certificate after completing the procedure.

The Authority states that registration results in allocating a VAT account number for the facility. The service is available to businesses that conduct a taxable economic activity and reach the mandatory or optional registration threshold.

Among the data that should be prepared before registering:

• Legal information related to the business.
• The Tax Identification Number (TIN).
• The commercial register or license linked to the activity.
• Revenues and supplies data.
• The National Address.
• Bank account information when needed.
• Activities and branches details.
• Information of the authorized person or legal representative.

VAT for Individuals

VAT applies to individuals in two different scenarios; the first is when the person is an end consumer, and the second is when they conduct an economic activity as a business owner.

The Individual as a Consumer

The consumer bears the VAT when purchasing goods and services subject to it. They usually do not submit a tax return for their personal purchases, and merely being an individual does not grant them the right to a tax refund.

The Individual Engaging in an Economic Activity

A person might own an establishment or work for themselves within an economic activity. When their annual revenues exceed 375,000 SAR, registration becomes mandatory, while they can register voluntarily if revenues range between 187,500 and 375,000 SAR.

After registering, the registered individual is obligated to:

• Issue the required invoices.
• Collect tax on taxable supplies.
• Record sales and purchases.
• File tax returns.
• Pay the net tax due.
• Retain records and documents.
• Claim eligible input tax deductions.

Also, personal expenses must not be mixed with business expenses, because the tax paid on personal purchases does not automatically become deductible input tax.

How to Calculate VAT

The method of calculating VAT differs based on whether the specified price is before tax or includes it.

Calculating Tax on a Tax-Exclusive Price

If the value of the good before tax is 1,000 SAR:

Tax = 1,000 × 15% = 150 SAR

Total including tax = 1,000 + 150 = 1,150 SAR

Extracting Tax from a Tax-Inclusive Price

If the final price inclusive of tax is 1,150 SAR:

Tax Amount = 1,150 × 15 ÷ 115 = 150 SAR

Value before tax = 1,150 − 150 = 1,000 SAR

Description	Tax-Exclusive Price	Tax-Inclusive Price
Value Before Tax	1,000 SAR	1,000 SAR
Tax Amount	150 SAR	150 SAR
Total	1,150 SAR	1,150 SAR

Calculating Tax After Discount

If the product's value reached 2,000 SAR, and the buyer received a discount of 200 SAR:

Value after discount = 2,000 − 200 = 1,800 SAR

Tax = 1,800 × 15% = 270 SAR

Total = 2,070 SAR

It is important to set the discount location and its calculation mechanism correctly within the system; a discount applied to a specific item might differ from a discount distributed across the total invoice, especially if the invoice includes more than one tax classification.

The Difference Between Output Tax and Input Tax

Output tax represents the tax the business collects from customers on its taxable sales, whereas input tax is the tax the business incurs when purchasing goods, services, and expenses related to its activity.

Comparison Element	Output Tax	Input Tax
Associated with	Sales	Purchases and Expenses
Who pays it to the facility?	The Customer	The facility pays it to the Supplier
Treatment	Tax Liability	May be deductible
Supporting Document	Sales Invoice	Compliant Purchase Invoice
Impact on the Return	Included in the tax due	Deducted when deduction conditions are met

The entire input tax cannot be automatically considered deductible; it must be related to the economic activity and eligible supplies, the necessary documents must be available, and it must not be among restricted or non-deductible expenses.

VAT Invoice

A VAT invoice is the document that compiles the details of the supplier, buyer, supply information, value of the good or service, tax, and the total amount due.

Depending on its type and the nature of the transaction, a tax invoice includes details such as:

• Name or title of the invoice.
• Supplier's name and address.
• VAT Registration Number.
• Required buyer's information.
• Sequential number.
• Invoice issue date.
• Date of supply if different.
• Details of products or services.
• Quantities and unit prices.
• Discounts.
• Tax rate and its amount.
• Total before and after calculating the tax.
• QR code and electronic data where applicable.

Invoices should be issued through an appropriate electronic solution, avoiding any unsystematic amendments to the original invoice after it is issued. As for subsequent returns, discounts, or increases, they are handled via credit or debit notes.

Using a Sales and Invoicing Management System, the invoice can be linked to inventory, the customer, payment method, and reports, rather than repeatedly entering the transaction into multiple programs.

Submitting the VAT Return

The VAT return is a periodic form through which a facility declares its sales and purchases data, output and input tax, and adjustments related to the tax period.

The submission process involves essential steps, including:

1. Logging into the facility's account on the Authority’s portal.
2. Opening the Indirect Taxes section.
3. Selecting Value Added Tax.
4. Entering the Tax Returns service.
5. Specifying the return to be submitted.
6. Entering the sales and purchases data.
7. Adding adjustments and modifications.
8. Reviewing the net tax.
9. Approving and submitting the return.
10. Receiving the submission acknowledgment and payment invoice if there is a due amount.

The Authority indicates that the return includes total sales and purchases data, and after submission, the taxpayer receives an acknowledgment of receipt of the return and an invoice value if there are dues.

Tax Periods and Return Submission Deadlines

Facilities whose annual supplies exceed 40 million SAR submit monthly tax returns, while facilities whose supplies are 40 million SAR or less submit quarterly returns, as confirmed by the Authority when announcing the return deadlines for 2026.

Size of Annual Supplies	Standard Return Period
More than 40 million SAR	Monthly
40 million SAR or less	Quarterly

The submission and payment deadline usually falls at the end of the month following the end of the tax period, and it is necessary to refer to the Authority’s calendar and specific notifications for the exact deadline. The compliance calendar for 2026 also includes separate deadlines for monthly and quarterly returns.

It is best not to delay the review until the last day, as the business needs time to ensure the accuracy and matching of:

• Sales with invoices.
• Point of sale data.
• Purchases with supplier invoices.
• Credit and debit notes.
• Tax balances with accounts.
• Branches and warehouses.
• Imported operations or transactions subject to the reverse charge mechanism where applicable.

Steps to Review the Return Before Submission

Before approving the return, it is important to conduct a series of verifications, including:

• Comparing total sales with the general ledger.
• Reviewing the alignment of sales with POS system data.
• Checking canceled invoices and returns.
• Ensuring credit and debit notes are properly recorded.
• Reconciling output tax with the tax account.
• Auditing purchase invoices.
• Excluding non-deductible input tax.
• Verifying exempt and zero-rated supplies.
• Reviewing branches data.
• Comparing results with the previous period.
• Investigating any unusual changes in numbers.
• Reconciling the balance with the Authority's account.
• Ensuring invoices are recorded in the correct period.

You can benefit from Operations and Reporting Management Solutions in tracking data related to invoices, returns, revenues, expenses, and reports, which helps in reviewing figures before preparing the return.

VAT Refund

A registered taxpayer can submit a request for a VAT refund when a credit balance appears in their tax account, provided they meet the requirements and attach the data and documents supporting the request.

The credit balance may arise due to multiple reasons, including:

• Eligible input tax exceeding output tax.
• Purchasing high-value assets or equipment.
• The existence of zero-rated supplies.
• Paying amounts that exceed the due tax.
• Making an amendment to a previous return.
• A balance carried forward from previous tax periods.

The Authority provides an electronic service to submit requests for refunds of credit balances; this requires having a credit balance and a bank account with an "IBAN". The service targets taxpayers registered for VAT.

Steps to Request a VAT Refund

A refund request can be submitted through the following procedures:

1. Logging into the Authority’s website using the taxpayer’s account.
2. Accessing the Indirect Taxes section.
3. Selecting Value Added Tax.
4. Opening the Payment Refunds service.
5. Creating a new refund request.
6. Specifying the balance and the period relevant to the request.
7. Verifying the bank account details.
8. Attaching the required documents.
9. Submitting the request.
10. Following up on notifications and any additional requests.

The Authority may request other documents or clarifications to confirm the validity of the credit balance, therefore sales and purchase invoices, adjustments, and account statements should be kept in an organized manner that is easy to reference.

VAT Refund Duration

According to the Authority's electronic service level agreement, the VAT refund duration is 30 working days.

The practical period begins after submitting a complete request, and procedures may be affected if additional documents are requested or if there is a need to review and evaluate the data. The Authority also clarifies that the VAT refund service is listed with an execution time of 30 working days.

To reduce chances of delay:

• Verify the correctness of the IBAN number.
• Match the refund value with the returns.
• Attach invoices and supporting documents.
• Review amendments made to previous returns.
• Explain the reasons for the creation of the credit balance.
• Respond to the Authority's requests in a timely manner.
• Do not claim amounts that are not supported by documents.

VAT Refund for Individuals

An individual consumer cannot automatically claim a refund for the VAT they paid on personal purchases. Therefore, one must distinguish between an ordinary consumer, an individual registered due to conducting an economic activity, and the categories allowed by the system to receive refunds according to regulations.

The VAT-Registered Individual

An individual who practices an economic activity and is registered for VAT can claim a deduction for eligible input tax related to their activity, while complying with the conditions applied to taxpayers, and distinguishing between business purchases and personal expenses.

Persons Eligible for a Refund

The Authority provides a service to register persons who meet the conditions for a VAT refund according to the specific regulations for each category. This requires submitting a registration request as an eligible person for refund and waiting for the Authority's notification of the result.

Therefore, it should not be generalized that "any individual can get a tax refund," because refund eligibility depends on the person's status, the nature of the expense, the existence of an economic activity, and the type of program or regulatory mechanism applicable to them.

Common Mistakes in Calculating VAT

Adding the Tax Twice

This error may occur when the displayed price already includes the tax, and then an employee adds a 15% rate to it again.

Calculating Tax Before Discount

The correct treatment of the discount should be determined first, then the tax is calculated according to the nature of the discount and the invoice.

Considering All Inputs Deductible

Not all expenses are eligible for tax deduction, and some might require applying proportional deduction.

Recording Tax as Revenue

Output tax collected from customers is not revenue or profit for the facility; it is a tax liability settled upon filing the return.

Using a Non-Compliant Supplier Invoice

An invoice lacking required data may affect the facility's ability to prove its right to deduct input tax.

Recording an Invoice in the Wrong Period

Entering an invoice in an incorrect period can lead to discrepancies between the return and the records, potentially requiring an amendment.

Confusing Exempt with Zero-Rated

An exempt supply is not the same as a zero-rated supply; each has different treatments and distinct effects on input tax deductions.

Not Linking Returns to the Original Invoice

Returns should be processed through a credit or debit note, and their impact should be linked to tax, accounts, and inventory.

Relying on Manual Calculation

Chances of errors increase when a business manages sales, purchases, inventory, and tax through separate files instead of connecting them within a single unified system.

Ignoring Branches

Data from branches, devices, and systems linked to the tax identification number must be correctly consolidated when preparing the return.

What is VAT Software?

VAT Software is an accounting or invoicing solution that helps a business classify tax transactions, perform calculations, issue invoices, record input and output tax, and prepare reports that can be used when preparing the tax return.

Among its most prominent required functions are:

• Setting tax rates and categories.
• Linking tax to items and services.
• Calculating sales tax.
• Recording purchase tax.
• Handling tax-inclusive and tax-exclusive prices.
• Distributing discounts.
• Issuing standard and simplified tax invoices.
• Managing credit and debit notes.
• Preparing output tax reports.
• Preparing input tax reports.
• Extracting invoice details.
• Tracking branches data.
• Managing user permissions.
• Keeping a transaction log.
• Integrating with e-invoicing.
• Exporting data for review.

Software cannot replace accounting audits; if an item, supplier, or account is misclassified, the system will execute the transaction incorrectly based on that specified setting.

Frequently Asked Questions

What is the VAT rate in Saudi Arabia?

The standard rate is 15% on goods and services subject to it, with some other transactions being zero-rated or exempt according to regulations.

How is VAT calculated?

When the price does not include tax, it is multiplied by 15%. If the price includes tax, its value is extracted by multiplying the total by 15 and then dividing it by 115.

What is the mandatory registration threshold?

Registration becomes mandatory when annual taxable supplies exceed 375,000 SAR.

What is the voluntary registration threshold?

Voluntary registration is possible when annual eligible supplies or expenses exceed 187,500 SAR without surpassing the mandatory registration threshold, in accordance with specified conditions.

Is VAT considered revenue for the company?

No, the tax a facility collects from a customer represents a tax liability, which is settled against input tax upon submitting the return.

Are individuals entitled to a VAT refund?

Not every consumer can automatically refund the tax. An individual registered due to conducting an economic activity can deduct eligible inputs, and there are specific categories entitled to refunds according to the rules.

How long does a VAT refund take?

The service level agreement defines the execution time for a refund request as 30 working days, and this period may be affected by the completeness of documents and audit results.

What are the conditions for a refund request?

It requires the applicant to be registered, have a credit balance, possess a valid IBAN, and provide supporting documents for the requested refund amount.

What is the difference between input and output tax?

Output tax is collected on sales, whereas the facility bears input tax on its purchases. The taxpayer then pays the difference between them after deducting eligible inputs.

Do all purchases grant the right to deduct tax?

No, purchases must be related to an eligible activity, the invoice and documents must be valid, and the expenses must not fall under non-deductible items.

When is the VAT return submitted?

Facilities whose annual supplies exceed 40 million SAR submit a monthly return, whereas other facilities generally submit quarterly returns, while adhering to the deadlines set by the Authority.

Can tax be calculated using Excel?

Excel can be used for auxiliary calculations, but it does not independently provide an integrated cycle covering invoices, inventory, accounts, permissions, and transaction logs, especially when the number of transactions is high.

Conclusion

Value Added Tax represents a major component of the sales, purchases, and accounting cycles in Saudi facilities. Compliance is not simply about adding a 15% rate to the invoice; it requires recording and accurately classifying transactions, distinguishing between input and output tax, preparing returns, maintaining documents, as well as tracking credit balances and refund requests.

An integrated accounting system helps reduce reliance on manual operations and links invoices to inventory, customers, suppliers, and reports, though the responsibility for the correctness of settings, classifications, and submitted documents ultimately remains with the facility.
