Section 2 — Required Inputs and Refusal Catalogue

2.1 Required Inputs

Minimum viable — Full-year audited (or draft) financial statements (income statement, balance sheet, cash flow), prior-year CIT/Zakat return as filed with ZATCA, Commercial Registration (CR) showing shareholder composition with nationality breakdown, articles of association, confirmation of fiscal year-end, sector classification (standard / natural gas / hydrocarbons / banking / insurance), and any TP-relevant related-party transaction summary.

Recommended — General ledger, fixed-asset register with depreciation schedule, related-party transactions schedule, withholding tax credit certificates, prior-year tax-loss carry-forward schedule (with Article 21 25% cap tracking), prior-year disallowed interest carry-forward (Article 12), advance tax payment receipts, ZATCA correspondence and prior assessments.

Ideal — Audited statements signed by a SOCPA-registered audit firm, complete tax computation reconciling accounting profit to taxable income, Master File / Local File / CbCR where group consolidated revenue exceeds SAR 750M, shareholder register with nationality and percentages, board resolutions for material elections, and confirmation of Pillar Two / DMTT scoping if part of an in-scope MNE group.

HARD STOP if minimum is missing. Without financial statements, the CR with shareholder nationality breakdown, and the prior-year return, no CIT computation may be produced — the Zakat/CIT split cannot be determined.

2.2 Refusal Catalogue

• R-SA-CT-1 — Saudi/GCC-only-owned entities. Companies wholly owned by Saudi or GCC nationals/entities are subject to Zakat, not CIT. Out of scope — see sa-zakat. (R-SA-CT-1)
• R-SA-CT-2 — Specialised sector regimes. Banking and insurance carry sector-specific computational rules beyond the rate. Out of scope except for the rate reference. Investment funds, mutual funds, and similar collective vehicles — out of scope. (R-SA-CT-2)
• R-SA-CT-3 — Group consolidated returns. Saudi tax law does not generally permit group consolidation. Specific share-deal structures may produce de facto consolidation effects — out of scope for this skill; refer to a SOCPA adviser. (R-SA-CT-3)
• R-SA-CT-4 — Special Economic Zones and incentive regimes. Includes the Regional Headquarters (RHQ) Program (30-year tax incentive package), the Integrated Logistics Bonded Zone (ILBZ), King Abdullah Economic City (KAEC), Ras Al-Khair, NEOM, and other zone-specific incentives. Out of scope — escalate to a SOCPA adviser familiar with the specific zone. (R-SA-CT-4)
• R-SA-CT-5 — Hydrocarbons upstream / oil and gas concessions. The tiered 50%–85% rates are referenced for completeness only. Actual computation involves concession-specific terms, cost-recovery mechanics, and Ministry of Energy interactions. Out of scope — escalate. (R-SA-CT-5)
• R-SA-CT-6 — Active ZATCA assessment / audit / appellate proceedings. Tax Violations and Disputes Resolution Committee (TVDRC), General Secretariat of Zakat, Tax and Customs Committees, or Court of Appeal proceedings — escalate. Do not produce numbers that pre-empt the dispute. (R-SA-CT-6)
• R-SA-CT-7 — Transfer-pricing controversy. Active APA, MAP, or controversy under the TP Bylaws — out of scope. (R-SA-CT-7)
• R-SA-CT-8 — Cross-skill scope. VAT → saudi-arabia-vat; e-invoicing → saudi-einvoice; withholding tax compliance → sa-withholding-tax; Zakat → sa-zakat; Real Estate Transaction Tax — separate skill (TBD). (R-SA-CT-8)
• R-SA-CT-9 — Pillar Two ambiguity. Where the Domestic Minimum Top-up Tax (DMTT) enactment status, scope, or effective date is uncertain, flag as TBC and decline to commit to a number until the gazetted instrument is verified. (R-SA-CT-9)
• R-SA-CT-10 — Tax treaty positions and PE determinations. Treaty-based PE analysis, Article 5 thresholds, treaty residency, and tie-breakers — escalate to a SOCPA adviser for any taxpayer claiming treaty relief. (R-SA-CT-10)

Section 3 — Tier 1 — Taxable Persons, Taxable Base, 20% Standard Rate

3.1 Taxable Persons

• Taxable persons — Saudi CIT applies to: 1. Non-Saudi/non-GCC shareholders of a resident company — taxed on their share of the company's taxable income (the company computes a single taxable income, then attributes the non-Saudi/GCC share to CIT and the Saudi/GCC share to Zakat — see "mixed entity" mechanics in §3.4 and §5.2). 2. Non-residents earning Saudi-source income — through a Permanent Establishment (PE) under Article 4 ITL or via specific transactional withholding regimes (see sa-withholding-tax). 3. Saudi PEs of non-residents — taxed on attributable income computed under Articles 4–5 ITL and Implementing Regulations. Saudi and GCC nationals are NOT subject to CIT. Their share is subject to Zakat instead (2.5% of the Zakat base — see sa-zakat). (ITL Articles 1–4 and Implementing Regulations)

3.2 Standard Rate — 20%

• Standard CIT rate — 20% of adjusted taxable income for: the foreign-shareholder share in a resident company; Saudi PEs of non-residents; non-resident persons earning Saudi-source business income. (Article 7(a) ITL)
• CIT standard formula — CIT = 20% × Adjusted Taxable Income (foreign-share portion or PE attributable income) (Article 7(a) ITL)
• Scope of standard rate — This rate applies to all sectors except (i) natural gas investment (30%), (ii) oil and other hydrocarbons (tiered 50%–85%), and (iii) any specific incentive regimes (out of scope). (Article 7(a) ITL)

3.3 Taxable Base — Adjusted Taxable Income

• Adjusted Taxable Income formula — Adjusted Taxable Income = Gross Income (Article 6) − Allowable Deductions (Articles 8–17) − Tax depreciation (Articles 17, declining-balance per asset class) − Loss carry-forward (Article 21, capped at 25% of annual taxable income) ± Adjustments per Implementing Regulations (Articles 5–6 ITL and Implementing Regulations)

Key adjustments (Articles 5–6 ITL and Implementing Regulations)

Item	Treatment
Provisions and contingent expenses	Generally non-deductible unless realised
Related-party expenses without arm's-length pricing	Disallowed to the extent non-arm's-length (TP Bylaws)
Interest expense	Deductible up to 50% of EBITDA (Article 12); excess carried forward
Bad debts	Deductible when written off and Article 13 conditions are met
Donations / charitable contributions	Deductible only if to a public-benefit entity approved by the relevant authority (Article 13(c) and Implementing Regulations)
Dividends paid	Not deductible
Income tax / Zakat paid	Not deductible
Withholding tax paid by the company (gross-up scenarios)	Specific Implementing-Regulation treatment — verify
Foreign tax	Foreign tax credit available under Article 6(c) and Implementing Regulations

3.4 Mixed-Entity Computation Mechanics

• Mixed-entity computation — Foreign-share portion = Total Adjusted Taxable Income × (Non-Saudi/GCC ownership %) CIT = 20% × Foreign-share portion Saudi/GCC-share portion = Total tax base for Zakat purposes × (Saudi/GCC ownership %) Zakat = 2.5% × Saudi/GCC Zakat base (see sa-zakat)
• Ownership percentage timing — The ownership percentages are taken from the Commercial Registration (CR) as of the last day of the fiscal year (or per the Implementing Regulations where a change occurred mid-year — verify).
• Conservative default — Use the CR snapshot at year-end; flag any mid-year ownership changes for reviewer to apportion correctly under the Implementing Regulations.

3.5 Permanent Establishment (PE) — Article 4 ITL

• Permanent Establishment — A non-resident has a Saudi PE where it carries on business through a fixed place of business in KSA, including: a branch, office, factory, workshop, or place of management; a building site, construction or installation project (subject to the duration threshold per the ITL / applicable treaty); the provision of services in KSA (subject to the services-PE threshold per the ITL / applicable treaty); a dependent agent habitually concluding contracts in KSA on behalf of the non-resident. (Article 4 ITL)
• Treaty override — Treaty positions override domestic-law thresholds where a treaty applies and the taxpayer claims treaty benefits. Treaty-based PE analysis is out of scope (R-SA-CT-10). (R-SA-CT-10)
• PE CIT formula — PE CIT = 20% × Adjusted Taxable Income attributable to the PE (Article 5 ITL)
• Attribution principle — Attribution follows the separate-enterprise principle under Article 5 and Implementing Regulations. (Article 5 ITL)

3.6 Loss Carry-Forward — Article 21

• Loss carry-forward formula — Loss carry-forward = Indefinite (no time limit) Annual offset cap = 25% of taxable income in the offset year (Article 21)
• Loss continuity — Losses may be carried forward indefinitely but the offset against any single year's taxable income is capped at 25% of that year's taxable income. Carry-back is not available. Loss continuity requires continuity of ownership and business activity (Implementing Regulations — verify the precise tests for material ownership changes). (Article 21)

3.7 Interest Deduction Limitation — Article 12

• Interest deduction cap formula — Maximum deductible interest = 50% × EBITDA EBITDA = Earnings before interest, tax, depreciation, and amortisation (Implementing-Regulation definition) (Article 12)
• Carry-forward of disallowed interest — Interest expense in excess of 50% of EBITDA is non-deductible in the current year and is carried forward for deduction in future years (subject to the same 50%-of-EBITDA cap in each future year). The cap applies on a per-entity basis (not consolidated) for standalone CIT computations. (Article 12)
• Conservative default — Compute the cap each year, track the disallowed amount as a carry-forward, and never deduct prior-year disallowed interest without confirming current-year EBITDA headroom.

Section 4 — Tier 2 — Sectoral Rates, Transfer Pricing, Pillar Two, Group Taxation

4.1 Natural Gas Investment — 30%

• Natural gas investment rate — Taxable income from natural gas investment activities is taxed at 30%. This rate covers upstream natural gas exploration, development, and production where the activity is classified as "natural gas investment" under the ITL and ZATCA guidance. (Article 7(b) ITL)
• Natural gas CIT formula — Natural Gas CIT = 30% × Taxable income from natural gas investment activities (Article 7(b) ITL)
• Scope narrow — Scope is narrow — verify with ZATCA / reviewer whether the activity is classified as natural gas investment or falls under standard 20% or the hydrocarbons tier. Activity boundary uncertainty defaults to 20% with a flag (do not apply elevated rates without confirmation).

4.2 Oil and Other Hydrocarbons — Tiered 50%–85%

Capital Base table (Article 7(c) ITL)

Capital Base	Indicative Rate
Above SAR 375 billion (largest concession holders)	85%
Mid-tier capital base	Sliding intermediate rates
Lower capital base (per the ITL schedule)	50% floor

(Reviewer: confirm the precise capital-base bands and intermediate rates against the current ITL text and ZATCA implementing guidance — the schedule has been updated by Royal Decrees in recent years.)

• Hydrocarbons CIT formula — Hydrocarbons CIT = (Tier rate per capital base) × Taxable income from oil/other hydrocarbons (Article 7(c) ITL)
• R-SA-CT-5 reference — Out of scope (R-SA-CT-5) — the rate is referenced only for completeness. Actual computation involves concession terms, cost recovery, and Ministry of Energy / ZATCA interactions. (R-SA-CT-5)

4.3 Banks and Insurance — Standard Rate with Sector Specials

• Banks and insurance treatment — The standard 20% rate generally applies to the foreign-share portion of banks and insurance companies, but the computational base carries sector-specific rules (provisioning, technical reserves, gross premium treatment, etc.). Sector-specific computational regimes are out of scope (R-SA-CT-2) beyond the rate reference. (R-SA-CT-2)

4.4 Group Taxation — Not Generally Available

• Group taxation — Saudi tax law does not generally permit group consolidated returns. Each resident entity files separately. Specific share-deal structures (mergers, demergers, share-for-share exchanges under Articles in the ITL and Implementing Regulations) may produce rollover or deferred outcomes, but these are out of scope (R-SA-CT-3) for this skill. (R-SA-CT-3)

4.5 Transfer Pricing — TP Bylaws (2019)

• TP Bylaws legislation — Transfer Pricing Bylaws issued by ZATCA (then GAZT) effective 2019, aligned with OECD BEPS Action 13. (Transfer Pricing Bylaws (2019))

Documentation requirements

Document	Threshold	Filing
Country-by-Country Report (CbCR)	Group consolidated revenue > SAR 750M (≈ EUR 750M / BEPS Action 13 threshold)	Annual filing by the Ultimate Parent or surrogate; KSA constituent files CbCR notification
Master File	Same SAR 750M threshold	Maintained and submitted to ZATCA upon request
Local File	KSA entity with related-party transactions above the prescribed threshold	Maintained and submitted to ZATCA upon request
Disclosure Form	All taxpayers with related-party transactions	Filed with the annual CIT return

• Arm's-length principle — Arm's-length principle applies to all related-party transactions. The five OECD methods are accepted (CUP, RPM, CPM, TNMM, Profit Split). Country-by-country reporting uses the same template and exchange mechanism as the OECD CbC Standard.
• Conservative default — For any group exceeding SAR 750M consolidated revenue, treat MF / LF / CbCR as required and flag for reviewer. For below-threshold groups, the Disclosure Form still applies — verify.

4.6 Pillar Two — Domestic Minimum Top-up Tax (DMTT) — TBC

• DMTT status — KSA has committed to OECD Pillar Two and is expected to implement a Domestic Minimum Top-up Tax (DMTT) effective 2025–2026. As of skill version 1.0 the precise enactment status, scope, and effective date are TBC — verify against the current ZATCA / Ministry of Finance instruments and the gazetted Royal Decree.
• Conservative default — For any MNE group with consolidated revenue ≥ EUR 750 million in at least two of the four preceding fiscal years (the Pillar Two scope threshold), flag DMTT applicability for reviewer. Do not compute a top-up amount until enactment is confirmed and the GloBE / DMTT rules are loaded into the workflow.

4.7 Withholding Tax — Cross-Skill Reference

• WHT cross-reference — WHT under Articles 68–69 ITL applies to certain payments from Saudi-resident payers to non-residents (e.g., royalties, technical services, management fees, dividends, interest, rent). Rates vary by category and treaty position. Detailed WHT compliance is out of scope — see sa-withholding-tax. WHT borne by the foreign-shareholder side of a mixed entity may interact with CIT credit mechanics — verify. (Articles 68–69 ITL)

Section 5 — Worked Examples

5.1 100% Foreign-Owned LLC — Standard 20%

Facts: GlobalTech Saudi LLC. Resident KSA company, 100% owned by a non-Saudi, non-GCC parent. Fiscal year 1 Jan 2025 – 31 Dec 2025.

• Gross income (Article 6): SAR 80,000,000.
• Deductible expenses (Articles 8–17, excluding interest): SAR 50,000,000.
• Interest expense: SAR 8,000,000.
• EBITDA (per Implementing Regulations definition): SAR 38,000,000.
• Tax depreciation: SAR 4,000,000.
• Prior-year loss carry-forward (Article 21): SAR 6,000,000.

5.1.1 Interest deduction limitation (Article 12).

Cap = 50% × EBITDA = 50% × 38,000,000 = SAR 19,000,000
Interest expense (SAR 8,000,000) ≤ Cap (SAR 19,000,000)
→ Full SAR 8,000,000 deductible. No carry-forward.

5.1.2 Taxable income (pre-loss).

Gross income                       SAR 80,000,000
Less: Deductible expenses         (SAR 50,000,000)
Less: Interest (within cap)        (SAR  8,000,000)
Less: Tax depreciation             (SAR  4,000,000)
                                   ───────────────
Taxable income (pre-loss)          SAR 18,000,000

5.1.3 Loss carry-forward (Article 21 25% cap).

Annual offset cap = 25% × 18,000,000 = SAR 4,500,000
Loss b/f                         = SAR 6,000,000
Loss applied this year (capped)  = SAR 4,500,000
Loss remaining for c/f           = SAR 1,500,000

5.1.4 CIT.

Adjusted taxable income = 18,000,000 − 4,500,000 = SAR 13,500,000
CIT @ 20%               = 20% × 13,500,000       = SAR  2,700,000

5.1.5 Filing.

Return due via ZATCA portal within 120 days of 31 Dec 2025 → by 30 April 2026. Tax payable with the return; quarterly advance instalments (Section 6.3) may have already discharged part of the liability.

5.2 60/40 Mixed Entity (40% Foreign, 60% Saudi/GCC)

Facts: Riyadh Trading Co. Resident KSA company. 60% Saudi nationals, 40% non-Saudi/non-GCC per the CR as at 31 Dec 2025. Fiscal year 1 Jan 2025 – 31 Dec 2025.

• Adjusted taxable income (per ITL): SAR 25,000,000.
• Zakat base (per Zakat regulations — see sa-zakat): SAR 30,000,000.

5.2.1 Foreign-share CIT.

Foreign-share portion = 40% × 25,000,000 = SAR 10,000,000
CIT @ 20%             = 20% × 10,000,000 = SAR  2,000,000

5.2.2 Saudi/GCC-share Zakat (reference — see sa-zakat).

Saudi/GCC-share Zakat base = 60% × 30,000,000 = SAR 18,000,000
Zakat @ 2.5%               = 2.5% × 18,000,000 = SAR    450,000

5.2.3 Total ZATCA liability.

CIT                          SAR 2,000,000
Zakat (cross-reference)      SAR   450,000
                             ─────────────
Total                        SAR 2,450,000

Filing: Single annual return via ZATCA portal within 120 days of 31 Dec 2025 → by 30 April 2026. CIT and Zakat reported on the integrated return (see Section 6).

Reviewer note: The Zakat base and the CIT taxable income are not the same number — they are computed under different rules. Always compute them independently. This example assumes the Zakat base is provided; the actual Zakat computation is delegated to sa-zakat.

5.3 Saudi PE of a Non-Resident

Facts: ForeignCo SARL (resident in a treaty country) operates a project office in Riyadh constituting a Saudi PE under Article 4 ITL. Fiscal year 1 Jan 2025 – 31 Dec 2025.

• Saudi-source revenue attributable to the PE: SAR 40,000,000.
• Allocable head-office expenses (under Implementing Regulations and the separate-enterprise principle): SAR 5,000,000.
• Local PE expenses (rent, salaries, depreciation): SAR 28,000,000.
• Adjusted taxable income attributable to the PE: SAR 7,000,000.

5.3.1 PE CIT.

PE CIT = 20% × 7,000,000 = SAR 1,400,000

5.3.2 Considerations.

• Treaty position: If ForeignCo's home jurisdiction has a treaty with KSA, the treaty may modify the PE threshold or the attribution rules — out of scope (R-SA-CT-10), escalate to reviewer.
• WHT interaction: Payments to the PE by Saudi customers may be subject to WHT under Articles 68–69; WHT borne is generally creditable against the PE's CIT liability subject to the Implementing Regulations — see sa-withholding-tax.
• Repatriation of branch profits: Saudi domestic law imposes a separate WHT on branch-profit remittances — verify the current rate and whether the treaty modifies it.

Filing: PE files a Saudi CIT return via the ZATCA portal within 120 days of fiscal year-end. Quarterly advance CIT instalments apply where the prior-year liability exceeds the threshold (Section 6.3).

Section 6 — Filing and Payment Mechanics

6.1 Annual Return — ZATCA Portal

Form: Integrated annual Zakat / Income Tax / WHT return — filed electronically via the ZATCA portal (zatca.gov.sa). Mixed entities file a single return that splits CIT and Zakat per ownership.

Required attachments / schedules

Schedule	Content
Main return	Computation of adjusted taxable income; CIT payable; Zakat payable for mixed entities
Audited financial statements	Attached
Schedule of related-party transactions / TP Disclosure Form	Required for all taxpayers with RPTs
Master File / Local File	If group consolidated revenue > SAR 750M (submitted on request)
CbCR notification / CbCR	If group consolidated revenue > SAR 750M
Schedule of loss carry-forward	Article 21 tracking with 25% annual cap applied
Schedule of interest carry-forward	Article 12 disallowed interest tracking
Schedule of WHT credits	Linked to sa-withholding-tax
Shareholder register snapshot	Nationality and ownership percentages for mixed-entity allocation

6.2 Filing Deadlines

Filing Deadlines table

Item	Deadline
Annual CIT return	Within 120 days of fiscal year-end (e.g., FYE 31 Dec 2025 → due 30 Apr 2026)
Annual tax payable balance	Due with the annual return
Quarterly advance CIT instalment 1	End of 6th month of the current fiscal year (verify per Implementing Regulations)
Quarterly advance CIT instalment 2	End of 9th month
Quarterly advance CIT instalment 3	End of 12th month
CbCR / Notification	Per ZATCA TP Bylaws schedule (typically aligned to BEPS Action 13 timing)
Extension request	Application to ZATCA; not automatic — must be filed before the deadline with justification

(Reviewer: confirm the advance-instalment due-date schedule against the current Implementing Regulations — historically advance instalments are tied to the 6th, 9th, and 12th months of the fiscal year, but verify.)

6.3 Advance CIT Instalments

• Advance instalments rule — Taxpayers whose prior-year tax liability exceeded a prescribed threshold must pay three advance instalments during the current fiscal year, each generally 25% of the prior-year liability (less specified credits), with the balance due on the annual return. (Article 60 ITL and Implementing Regulations)
• Advance instalment formula — Per-instalment amount ≈ 25% × Prior-year CIT (less applicable credits per Implementing Regulations) Balance with annual return = Current-year CIT − advance instalments − WHT credits (Article 60 ITL and Implementing Regulations)
• Reduction and conservative default — If the taxpayer reasonably estimates that the current-year liability will be materially lower, it may apply to ZATCA to reduce the instalments — subject to default surcharge if the year-end liability exceeds the reduced basis. Conservative default: Pay on the prior-year basis unless a formal reduction is approved by ZATCA.

6.4 Penalties

Penalties table

Infraction	Sanction
Late payment of tax	5% per month of the unpaid tax, capped at 25% of the unpaid amount
Failure to file the annual return on time	Tiered fine per ZATCA schedule (verify current amounts)
Failure to maintain records	Per ZATCA schedule
Tax evasion (intentional)	Up to 25% of the evaded tax plus criminal exposure under the ITL penal provisions
Failure to file CbCR / MF / LF where required	Per TP Bylaws penalty schedule
Late or short advance instalment	Default surcharge per the Implementing Regulations

• Conservative default — Apply 5%/month capped at 25% for late-payment scenarios and flag any other penalty interaction for reviewer to confirm against the current ZATCA penalty schedule.

6.5 Audit, Assessment, and Statute of Limitations

• Audit and limitations — - Self-assessment — the return as filed forms the basis of assessment unless ZATCA selects for audit. - Audit selection — ZATCA may select on a risk basis or by sector campaign. - Statute of limitations — generally 5 years from the filing of the return, extendable in cases of suspected concealment or fraud (verify against the current ITL / ZATCA guidance). - Disputes — Tax Violations and Disputes Resolution Committee (TVDRC) → General Secretariat of Zakat, Tax and Customs Committees → Court of Appeal.

Section 8 — Sources

Primary Legislation

• Income Tax Law (ITL) — Royal Decree No. M/1 dated 15/1/1425H (6 March 2004).
  • Article 1–4 — taxable persons, residency, permanent establishment.
  • Article 5 — separate-enterprise principle for PEs.
  • Article 6 — gross income.
  • Article 7 — rates (a) 20% standard, (b) 30% natural gas, (c) 50%–85% oil and other hydrocarbons.
  • Articles 8–17 — allowable deductions.
  • Article 12 — interest deduction limitation (50% of EBITDA).
  • Article 13 — bad debts, donations, and specific deduction conditions.
  • Article 17 — depreciation (declining-balance per asset class).
  • Article 21 — loss carry-forward (indefinite, capped at 25% of annual taxable income).
  • Article 60 — advance tax instalments.
  • Articles 68–69 — withholding tax on payments to non-residents.
• Implementing Regulations to the ITL — detailed procedural and computational rules issued by ministerial decision.
• Subsequent Royal Decrees and Ministerial Decisions amending the ITL and Implementing Regulations (verify the current consolidated text).

Subordinate Legislation and ZATCA Instruments

• Transfer Pricing Bylaws (2019) — BEPS Action 13 aligned; MF / LF / CbCR thresholds at SAR 750M.
• ZATCA Circulars and Guides — including TP guide, withholding-tax guide, and sectoral guides.
• Pillar Two / Domestic Minimum Top-up Tax instruments — TBC for 2025–2026 enactment; verify the gazetted Royal Decree and ZATCA implementing rules.

Authority and Platform

• Zakat, Tax and Customs Authority (ZATCA) — zatca.gov.sa.
• ZATCA portal — annual return filing, advance instalments, WHT filings, TP disclosure.
• General Secretariat of Zakat, Tax and Customs Committees — disputes and appeals (out of scope).

International Instruments

• OECD Model Tax Convention and KSA bilateral tax treaties — for treaty-based PE and WHT analysis (escalate per R-SA-CT-10).
• OECD BEPS Action 13 — Master File / Local File / Country-by-Country Reporting standard.
• OECD Pillar Two GloBE Rules — informing the KSA DMTT track (TBC).

PROHIBITIONS

• NEVER apply Saudi CIT to Saudi or GCC nationals' share — that share is subject to Zakat (see sa-zakat).
• NEVER apply the standard 20% rate to taxable income from natural gas investment (30%) or oil and other hydrocarbons (tiered 50%–85%) — but equally, do not apply elevated rates without confirmation of activity classification (default to 20% with a flag).
• NEVER omit the Article 21 25% annual cap on loss carry-forward offset — losses are indefinite but cannot eliminate more than 25% of any year's taxable income.
• NEVER deduct interest in excess of 50% of EBITDA under Article 12 — track the disallowed amount as a carry-forward.
• NEVER produce a Saudi consolidated/group return — Saudi tax law does not generally permit it (R-SA-CT-3).
• NEVER apply a Regional Headquarters (RHQ), ILBZ, NEOM, KAEC, or other zone incentive without specialist verification (R-SA-CT-4).
• NEVER assume a tax treaty modifies the PE or WHT outcome without reviewer sign-off (R-SA-CT-10).
• NEVER compute Pillar Two / DMTT amounts until the gazetted KSA instrument is verified — mark TBC in all interim outputs.
• NEVER apply CbCR / MF / LF thresholds inconsistently — the SAR 750M consolidated-revenue threshold is the trigger.
• NEVER advise late filing — the 120-day deadline is strict and the penalty is 5% per month capped at 25%.
• NEVER advise skipping or reducing advance instalments without formal ZATCA approval — default surcharge applies.
• NEVER conflate the CIT taxable income and the Zakat base in a mixed entity — they are computed under different rules.
• NEVER ignore the Commercial Registration nationality breakdown — it drives the CIT/Zakat split in a mixed entity.
• NEVER produce figures as definitive — always label as estimates pending reviewer sign-off by a SOCPA-licensed tax professional.
