Civil Law and Civil Procedure in Tax Disputes
This domain tests the civil law concepts that determine ownership, contracts, agency and evidence in tax disputes, together with procedural principles used by tax boards.
Core rules
- Under Article 10 of the Civil Code, contracts bind the parties unless contrary to law. Article 190 sets conditions for validity, and Article 219 supports specific performance. Tax examiners must respect valid contracts but may examine their substance and pricing.
- The burden of proof is generally on the claimant under Article 1257. Documentary evidence is central under Article 1284, and expert evidence may be ordered where technical facts are disputed.
- Agency (وکالت), representation, guarantee and lease rules determine who may act and who bears obligations. A tax consultant’s authority must be documented.
- Civil procedure principles include proper service, jurisdiction, the right to be heard, reasoned decisions and appeal. Tax boards apply these principles, although their procedure is specialized.
- Limitation periods and procedural deadlines can extinguish a claim even where the substantive right exists.
Worked example
A taxpayer claims a 600 million rial sale was made at below market value to a related party. The written contract is valid between the parties under Article 10, but the tax office challenges the price and obtains an expert valuation of 800 million. The board reviews the contract, the expert report and the burden of proof. The contract’s civil validity does not automatically fix the tax base; the board may accept the valuation and assess the difference.
Traps
Confusing civil validity with tax deductibility; missing a limitation or service issue; relying on an unsigned contract; failing to prove agency authority; and assuming tax boards are bound by ordinary court procedure in every detail.
