The General Deduction Principle
Article 12 of the Saudi Income Tax Law establishes the foundational rule for deductible expenses:
All regular and necessary expenses of earning taxable income, paid or accrued, incurred by the taxpayer during the taxable year are deductible.
This means that to qualify for a deduction, an expense must be:
- Regular and necessary — ordinary costs of doing business
- Directly connected to earning taxable income
- Incurred during the relevant taxable year
- Not of a capital nature (capital expenditure is handled through depreciation)
---
Expenses That Cannot Be Deducted
Article 13 explicitly blocks deductions for:
- Expenses not connected to earning taxable income
- Excessive payments to shareholders, partners, or their relatives (salaries, bonuses, or benefits that do not reflect genuine commercial terms)
- Fines, penalties, and similar charges imposed by authorities
- Personal expenditure of any kind
- Capital expenditure treated as assets rather than day-to-day costs
Practical warning for expats: If you pay family members through your Saudi business, those payments will only be deductible if they reflect genuine market-rate remuneration for actual services rendered. Inflated salaries to relatives are a common audit trigger.

Depreciation of Business Assets
Since capital costs cannot be deducted in full in the year of purchase, Article 17 provides for depreciation deductions. Key points include:
- Depreciation applies to tangible and intangible assets that lose value through use or obsolescence
- Land cannot be depreciated
- Assets are grouped into depreciation pools, and a fixed annual rate is applied to the pool balance
- When an asset is sold, the proceeds are credited back into the pool
Common depreciation rates under the Regulations include:
- Buildings and structures: typically 5%
- Computers and IT equipment: 25% or higher
- Machinery and equipment: 25%
- Intangible assets (goodwill, patents, etc.): 10%
Always verify current rates with a Saudi tax adviser as Regulations can be updated.

Repairs and Improvements
Under Article 18, costs for repairing or improving depreciable assets are deductible, but with a cap:
- Maximum deductible repair/improvement costs per year: 4% of the opening pool balance for each asset group
- Any excess over this cap is added to the pool and depreciated over time

Bad Debt Deductions
Article 14 allows businesses to deduct bad debts — money owed to you that cannot be collected — provided:
- The amount was previously declared as taxable income
- The debt has been written off in your books
- There is sufficient evidence that the debt cannot be collected
Practical tip: Maintain thorough records of collection attempts, correspondence with debtors, and any legal proceedings. ZATCA may require evidence before allowing a bad debt deduction.

Research and Development Expenses
Article 16 permits deductions for R&D expenses connected to earning taxable income. However:
- Land and equipment purchased for R&D cannot be expensed directly — they must be depreciated
- Only genuine R&D costs with a clear link to your income-generating activity qualify
---
Retirement Fund Contributions
If you employ staff in Saudi Arabia, Article 20 allows deductions for employer contributions to authorised retirement funds, subject to:
- The fund being established in accordance with Saudi laws
- The deduction per employee not exceeding 25% of that employee's annual compensation
This is a useful tool for structuring competitive employment packages while managing your tax base.

Charitable Donations
Under Article 11, donations are deductible if paid to:
- Public agencies or philanthropic societies licensed in the Kingdom
- Organisations that are nonprofit and authorised to receive donations
Unsolicited or informal donations are unlikely to qualify — always obtain documentation from the recipient organisation.
---
Carrying Forward Business Losses
Article 21 provides welcome relief for businesses that make a loss in any year:
- A net operating loss can be carried forward to subsequent taxable years
- The loss is offset against future taxable income until fully absorbed
- The Regulations specify the maximum carry-forward period (typically unlimited for trading losses, but confirm with a local adviser)
Practical tip for start-ups and early-stage expat businesses: Early losses are not wasted — plan your business cycle to ensure losses are properly documented and carried forward.

Geological and Natural Resource Costs
Article 19 provides specific rules for geological surveying and preliminary natural resource extraction costs — these are amortised over time rather than expensed immediately. Relevant mainly for expats in the oil, gas, or mining sectors.

Summary Checklist for Expats Claiming Deductions
- [ ] Is the expense directly connected to earning taxable income?
- [ ] Is it a revenue expense (not capital)?
- [ ] Have you retained documentation (invoices, contracts, payment records)?
- [ ] Are payments to related parties at arm's length market rates?
- [ ] Have bad debts been formally written off with supporting evidence?
- [ ] Are depreciation claims correctly calculated using approved pool rates?
Proper deduction planning can substantially reduce your effective tax rate in Saudi Arabia. Work with a ZATCA-registered tax adviser to ensure your deductions are correctly structured and documented.
