White Land Tax Reform: Potential Supply Pipeline Impact Assessment

White Land Tax Reform: Potential Supply Pipeline Impact Assessment

The White Land Tax reform under Royal Decree M/244, approved in April 2025 and published in the official gazette in May 2025, represents the most aggressive land mobilisation policy in Saudi Arabia’s housing history. By applying progressive tax rates up to 10 percent on over 5,500 vacant plots covering approximately 411 million square metres across Riyadh, Jeddah, Makkah, and Dammam, the reform transforms the economics of urban land holding — converting passive ownership from a cost-free speculative position into an actively penalised one.

The Progressive Rate Structure

The revised law replaces the earlier flat rate of 2.5 percent with a tiered structure reaching up to 10 percent of land value, depending on development priority, location, and market conditions. This progressive design allows the government to calibrate tax pressure geographically and temporally — applying maximum rates to the most in-demand urban zones where land hoarding creates the greatest housing supply constraint, while applying lower rates to peripheral areas where development urgency is lower.

The 5,000 square metre threshold is retained from the original law, meaning that smaller plots below this threshold are exempt. This threshold ensures the tax targets institutional and large-scale landowners rather than individual homeowners with modestly sized vacant parcels. The extension to vacant buildings in urban areas closes a loophole that previously allowed owners to construct minimal structures on land to avoid white land tax classification while effectively keeping the property undeveloped and unproductive.

Scale of the Land Inventory

The 5,500 identified vacant plots covering approximately 411 million square metres represent an extraordinary development potential. To contextualise this area: 411 million square metres equals 411 square kilometres — an area larger than many major cities globally. Even at moderate residential density, this land could theoretically accommodate millions of housing units.

The distribution across four cities — Riyadh, Jeddah, Makkah, and Dammam — targets the markets where housing demand is most acute and price pressures most severe. Riyadh, where apartment prices have surged 82 percent since 2019 and residential prices climbed 10.6 percent year-on-year in Q2 2025, contains a significant portion of the identified vacant land. The presence of hundreds of square kilometres of undeveloped urban land in a city experiencing double-digit annual price growth illustrates the supply-demand disconnect that the white land tax aims to resolve.

At 10 percent annually, a SAR 100 million vacant plot faces SAR 10 million in annual tax — a carrying cost that makes passive holding economically unsustainable. Over five years, the cumulative tax liability would reach SAR 50 million, or 50 percent of the land’s assessed value, assuming no appreciation. This punitive carrying cost creates a clear economic incentive: develop the land, sell it to developers, or face tax obligations that erode the value of the holding.

Scenario Analysis: Development Pipeline Implications

The impact of the white land tax on housing supply depends on how landowners respond. Several scenarios illustrate the range of potential outcomes.

Conservative scenario (10 percent release). If 10 percent of identified land enters the development pipeline — approximately 41 million square metres — the supply impact would still be substantial. At typical Saudi residential density of 40-50 units per 10,000 square metres for villa-type developments, 41 million square metres could yield 164,000-205,000 housing units. For apartment-oriented development at higher densities, the yield could exceed 400,000 units. Even the conservative scenario would provide meaningful support to NHC’s 600,000-unit target and ROSHN’s 400,000-unit mandate.

Moderate scenario (20 percent release). If 20 percent of identified land — approximately 82 million square metres — enters the pipeline, the potential unit yield doubles to 328,000-410,000 units for villa development or 800,000+ for apartment development. This volume would substantially exceed the remaining delivery needed to support the homeownership programme’s final push to 70 percent, though not all units would be completed within the programme’s timeline.

Aggressive scenario (30+ percent release). If the progressive rates and enforcement mechanisms motivate 30 percent or more of landowners to develop or sell, the resulting land supply could fundamentally reshape the market, potentially creating oversupply conditions that moderate prices beyond what the government intended. This scenario, while beneficial for affordability, carries risks for developers already committed to projects at current land costs and for the mortgage market’s credit quality.

Timeline and Conversion Lag

The critical constraint on white land tax impact is the land-to-housing conversion timeline. Vacant urban land does not become habitable housing overnight. The typical development cycle includes master planning (6-12 months), infrastructure development (12-24 months), building construction (18-36 months), and completion and handover (3-6 months). End-to-end, the minimum conversion period is approximately 3 years for well-organised projects, with 4-5 years being more typical for larger developments.

This timeline positions the meaningful supply impact of white land tax-motivated development in the 2028-2030 window — squarely within Phase 3 of the Housing Program Delivery Plan, which focuses on achieving maturity and launching new initiatives to reach the 70 percent homeownership target. The alignment is potentially advantageous: if supply from white land tax-motivated development arrives as the programme enters its final push toward the target, it provides an additional supply buffer that improves the probability of success.

However, the timeline also means that the tax’s effects on current market conditions are indirect. In the near term (2025-2027), the white land tax affects landowner expectations and decision-making, potentially moderating speculative land price appreciation as the carrying cost of holding makes accumulation less attractive. This expectation effect — separate from actual development activity — can influence market sentiment and pricing even before physical supply materialises.

Interaction with NHC and ROSHN

White land tax-motivated land sales can directly benefit NHC and ROSHN by expanding the pool of development-ready urban land available for acquisition. NHC manages 39 major projects across 17 cities and has established 25 urban destinations. If private landowners facing escalating tax obligations choose to sell to institutional developers rather than develop independently, NHC and ROSHN gain access to strategically located urban parcels that expand their community portfolios.

ROSHN’s SEDRA community in Riyadh spans 20 million square metres — approximately 5 percent of the total identified white land inventory. If white land tax releases an additional 80-120 million square metres in Riyadh alone, ROSHN could potentially expand its Riyadh communities several-fold, addressing the gap between its current 85,000-unit pipeline and 400,000-unit target. Knight Frank’s estimate that ROSHN would need 115,000 units per year for six years becomes more achievable if land availability improves.

At the Restatex Riyadh 2026 event, SEDRA and WAREFA communities secured SAR 2.14 billion in land sale and development agreements. The Alramz Real Estate agreement for two residential plots with 240 units on 14,128 square metres illustrates the model: white land tax pressure on adjacent landowners could create a pipeline of similar parcels available for development, enabling continuous community expansion.

Developer Ecosystem Response

The white land tax creates opportunities for the Kingdom’s 310 certified developers (including 70 newly qualified under the Developer Support Program) to acquire and develop land that was previously held off-market. The 63 percent increase in small and medium project licenses demonstrates growing developer capacity at the smaller scale — precisely the segment likely to develop individual white land parcels that are too small for NHC or ROSHN but viable for boutique residential projects.

The Wafi programme’s off-plan licensing system, with 434 approved projects and 350 qualified developers, provides the regulatory framework for new developments on released white land parcels. Escrow requirements, completion-milestone payments, and the 5 percent reservation deposit cap protect buyers in these new projects. The 1,130 field inspections in 2023 and 68 percent reduction in fraud and non-delivery rates since 2022 ensure enforcement extends to white land tax-motivated developments.

International developers, including those involved in the Chinese developer agreements for 100,000 homes and the Cityscape Global partnerships, could access white land tax-released parcels through joint ventures with Saudi landowners. The foreign ownership law effective January 2026 enables these partnerships, though foreign investors acquiring vacant land face the same white land tax obligations as domestic owners — preventing foreign capital from simply replacing domestic speculative holding.

Market Price Impact

The white land tax’s impact on housing prices operates through two channels: land price moderation and increased housing supply.

Land represents a significant component of total housing cost — typically 30-50 percent of finished unit prices in urban Saudi Arabia. If white land tax pressure reduces land price growth or forces actual price declines as landowners compete to sell, the resulting savings pass through to lower finished housing costs. This land price moderation directly supports affordability for Sakani-eligible families and private-market buyers.

The supply channel operates with the 3-5 year lag discussed above. As white land tax-motivated developments complete and enter the market in 2028-2030, the increased supply of finished units creates competitive pricing pressure that benefits buyers. Combined with ongoing NHC and ROSHN delivery, the additional supply from white land tax-released parcels could create market conditions where the supply-demand balance shifts in buyers’ favour for the first time since the post-2019 price surge.

The Riyadh rent freeze interacts with white land tax effects in the capital. Frozen rental income reduces the investment return on completed rental properties in Riyadh, while the white land tax penalises vacant land holding. Together, these policies channel capital toward the most productive use — developing land into housing that is sold rather than rented, aligning investor incentives with the homeownership programme’s objectives.

Mortgage Market Implications

Increased housing supply from white land tax-released development supports the mortgage market’s growth trajectory toward SAR 1.3 trillion by 2030. More available units create more mortgage origination opportunities for banks. SAMA’s rate cuts to 4.25 percent provide the demand-side conditions for these mortgages, while SRC’s refinancing capacity (exceeding SAR 12 billion in completed deals, targeting SAR 75 billion over five years) ensures banks can recycle mortgage capital to fund continued origination.

If white land tax-motivated supply arrives at moderate price points — reflecting the lower land costs created by tax-driven selling — the resulting mortgages will have lower principal amounts and correspondingly lower default risk. This improves the credit quality of the mortgage asset base and supports the development of the RMBS market, where asset quality determines investor appetite and pricing.

Enforcement Challenges

The white land tax’s effectiveness depends on enforcement. Assessment of land values — the basis for calculating tax obligations — requires a functioning land valuation system. The 5,500 identified plots represent the registry of taxable land, but ongoing identification of additional plots, reassessment of values as market conditions change, and collection of tax obligations all require sustained administrative capacity.

The Saudi real estate market is forecasted to grow from over USD 75 billion in 2025 to nearly USD 110 billion by 2030. As land values appreciate within this growing market, tax obligations increase proportionally under the ad valorem structure — creating a self-reinforcing dynamic where market growth amplifies white land tax pressure on landowners. This dynamic works in the government’s favour as long as enforcement keeps pace with market growth.

REGA’s role as the central regulatory body for real estate positions it as the likely enforcement authority for white land tax collection. REGA’s FAL licensing system, mandatory registration requirements, and field inspection infrastructure provide existing enforcement capacity that could extend to white land tax compliance monitoring.

Assessment

The white land tax reform represents the supply-side complement to the housing programme’s demand-side interventions (Sakani subsidies, SAMA rate cuts, Dhamanat guarantees). Its potential impact — releasing a portion of 411 million square metres of vacant urban land for development — could generate hundreds of thousands of housing units over the 2028-2030 period. The progressive rate structure up to 10 percent creates carrying costs that make passive land holding economically irrational, while the extension to vacant buildings closes evasion routes. The 3-5 year conversion timeline means the tax’s full supply impact will materialise in Phase 3 of the housing programme, when the final homeownership push to 70 percent requires maximum supply availability.
