What Is Input Tax and Why Does It Matter?
Input Tax is the VAT you pay when you purchase goods or services for your business. When you are VAT-registered, you are generally entitled to deduct this Input Tax from the Output Tax you collect from your customers. This prevents VAT from accumulating as a cost at each stage of the supply chain.
For example:
- You purchase office equipment for SAR 10,000 + SAR 1,500 VAT
- You provide consultancy services and charge a client SAR 20,000 + SAR 3,000 VAT
- Your Net VAT payable = SAR 3,000 (Output Tax) – SAR 1,500 (Input Tax) = SAR 1,500
What Input Tax Can You Deduct? (Article 49)
Under Article 49, you can deduct Input Tax on goods and services supplied to you, provided they are received in the course of carrying on an Economic Activity and relate to:
- Taxable Supplies you make (including zero-rated supplies)
- Certain other qualifying business uses specified in the Regulations
You cannot deduct Input Tax on purchases that relate to:
- Exempt supplies (such as residential real estate rentals or most financial services)
- Personal expenses or non-business use
- Entertainment, hospitality, or similar expenses where restrictions apply
- Purchases where you do not hold a valid Tax Invoice to support the claim
The Partial Deduction Rule for Mixed Businesses
If your business makes both taxable and exempt supplies, you cannot reclaim all of your Input Tax. You must apportion it:
- Identify Input Tax that relates exclusively to taxable supplies — fully deductible
- Identify Input Tax that relates exclusively to exempt supplies — not deductible
- For costs that relate to both (overhead, rent, utilities), apply an apportionment formula approved by ZATCA
Getting this apportionment wrong is one of the most common VAT errors for businesses with mixed income streams. Keep clear records that link each purchase to its intended business use.
What Is the Reverse Charge Mechanism? (Article 47)
The Reverse Charge Mechanism (RCM) applies when a non-resident supplier provides goods or services to a Taxable Person in Saudi Arabia. Instead of the foreign supplier charging and remitting VAT, the Saudi-based customer is responsible for both:
- Reporting the Output Tax on that supply (as if they had charged themselves VAT)
- Claiming the corresponding Input Tax (if the purchase is for a qualifying business purpose)
In many cases, these two amounts cancel each other out — but you must still report both on your VAT return.
When Does the Reverse Charge Apply?
The Reverse Charge applies when:
- You purchase services from a supplier based outside any GCC Member State
- The supplier has no place of residence in Saudi Arabia or the GCC
- You are a registered Taxable Person receiving the supply for business purposes
Common examples for expats:
- Subscribing to overseas software or cloud services (e.g., Microsoft 365, AWS)
- Hiring foreign consultants or freelancers based outside the GCC
- Using international marketing or advertising platforms
What You Must Do Under the Reverse Charge
- Calculate the VAT on the value of the supply at the standard rate (15%)
- Report Output Tax in Box/field for reverse charge supplies on your VAT return
- Claim Input Tax in the corresponding section, subject to normal deductibility rules
- Retain documentation of the purchase and the basis for applying the Reverse Charge
Input Tax on Imports (Articles 43 and 44)
When you import goods into Saudi Arabia:
- You must provide your TIN to the Customs Department at the point of entry
- By default, VAT on imports is collected by Customs at the border
- Under Article 44, you can apply to ZATCA to pay import VAT through your VAT Return instead of at the border — this is an important cash flow benefit worth applying for if you import regularly
Once you have paid import VAT (either at the border or through your return), you can claim it as Input Tax in the normal way, provided the imports are for qualifying business purposes.
The Profit Margin Scheme for Used Goods (Article 48)
If your business buys and sells used goods (second-hand items), you may apply to ZATCA to use the profit margin method. Under this approach:
- VAT is only calculated on your profit margin, not the full sale price
- This prevents double taxation on goods that have already been subject to VAT
- You cannot use this method until ZATCA formally approves your application
Practical Tips for Maximising Your Input Tax Recovery
- Always obtain a valid Tax Invoice for every business purchase before claiming Input Tax
- Implement a clear expense policy distinguishing business from personal costs
- Review your overseas supplier contracts to identify where Reverse Charge obligations arise
- Apply to pay import VAT through your VAT return to improve cash flow
- If you have exempt income, work with an accountant to set up a proper Input Tax apportionment method from the start
- Keep records for at least five years — ZATCA can audit past periods under Article 64
