Short Definition
Total rental revenue before any expense deductions, used for calculating occupancy rates and gross return on investment.
Overview
Legal Basis
Gross income calculation is based on accounting principles adopted by SOCPA and IFRS standards applied in Saudi Arabia. It is subject to the Value Added Tax Law issued by Royal Decree No. (M/113) of 1438 AH, where gross income from commercial property is the basis for calculating 15% VAT. It is also subject to the Zakat and Income Law for ZATCA, and corporate financial disclosure regulations. Commercial entities are required to keep books that accurately show gross income, used in tax declarations and administrative disclosures.
Practical Example
Nouf owns a multi-use commercial building in Riyadh: 6 commercial shops on ground floor (annual rent SAR 24,000 per shop), 12 apartments on upper floors (annual rent SAR 30,000 per apartment), parking with 40 spots (8 leased to nearby company at SAR 600 monthly per spot), large advertisement on building facade (SAR 24,000 annually). Annual gross income: shops 6×24,000 = 144,000, apartments 12×30,000 = 360,000, parking 8×600×12 = 57,600, advertisement 24,000. Total: SAR 585,600 gross income. Later, 15% VAT is calculated on commercial portion only (144,000 + 57,600 + 24,000 = 225,600 × 15% = SAR 33,840), and expenses are deducted to reach net income. This detailed analysis enables Nouf to know which income source is more profitable, and where opportunities exist to increase revenues.
Common Mistakes
- ✗Considering expected gross income as actual revenues — expectations may differ from reality due to vacancies and late payments.
- ✗Overlooking sub-revenues in calculation — parking, advertisements, services may form 5-15% of gross income.
- ✗Mixing commercial and residential gross income in VAT calculation — residential is exempt from VAT, commercial is subject to 15%.
- ✗Calculating VAT as part of gross income — VAT is collected on behalf of ZATCA and is not income for the owner.
- ✗Assuming higher gross income means higher profitability — may be accompanied by higher expenses consuming the increase.
International Differences
Gross income concept is global and unified, with differences in sub-revenue details. In the UAE, includes rental revenues + community services. In Turkey, gross income (Brüt Gelir) is the basis for income tax calculation, including all sub-revenues. In Egypt, inflation makes comparing gross income across years difficult without value adjustment. In the UK, Gross Rental Income is a standard in property valuation, used in Yield calculation. In the US, Gross Potential Income (GPI) versus Effective Gross Income (EGI) is a common distinction in property analysis. The Saudi advantage in gross income calculation is comprehensiveness (includes all sources), integration with ZATCA for automatic VAT, and linking with the Ejar platform to obtain real and documented data without relying on owner estimates only.
