OECD: Netherlands Offers Europe’s Highest Tax Relief for Homeowners, Widening Housing Gap

OECD Report: Netherlands Offers Europe’s Highest Homeowner Tax Relief

The Organisation for Economic Cooperation and Development (OECD) has concluded that the Netherlands offers the most generous tax relief for homeowners among its 38 member countries, nearly double that of the runner-up Chile. While intended to support aspiring buyers, these incentives have inadvertently driven up property prices, widened the gap between homeowners and renters, and exacerbated housing shortages. As affordability concerns mount, policymakers and market watchers are calling for a balanced rethink of homeownership incentives and rental sector reforms.

The Role of Homeownership Incentives in Rising Prices

Mortgage interest deductions (MID) are at the heart of the debate. Under the current Dutch system, homeowners can deduct mortgage interest payments from their taxable income, reducing their housing costs substantially. This measure is compounded by other generous policies:

• Tax deductibility of mortgage interest: Owners subtract interest payments from taxable income for up to 30 years.
• Low taxation of imputed rent: A notional rental income—an imputed rent—for owner-occupied homes is lightly taxed.
• Exemptions on capital gains: Private homeowners rarely pay tax on gains realized when selling a primary residence.
• State guarantees and high loan-to-value (LTV) ratios: Buyers can borrow up to 100% of a home’s value, often backed by government guarantees.

These combined incentives make homeownership appear not just affordable but highly attractive as a wealth-building tool. However, by stimulating demand more rapidly than supply can catch up, they put persistent upward pressure on Dutch house prices.

Affordability Pressures and Growing Inequality

With tax relief tilted heavily towards homeowners, the gap between owner-occupiers and renters is widening. Renters do not benefit from mortgage deductions and often face strict rent controls and bans on buy-to-let investments, reducing the availability of private rental properties. As a result:

• Lower and middle-income households struggle to compete in a market where bidding wars drive prices beyond reach.
• The private rental sector remains thin, forcing many into the regulated segment with limited availability.
• Wealth accumulation through real estate becomes concentrated among those with existing assets or family support.

The OECD notes that shifting support away from ownership and towards expanding the rental supply could help rebalance the market, making housing more accessible for a broader population.

OECD Recommendations for Policy Reform

In its 2025 Economic Survey of the Netherlands, the OECD proposes a two-pronged approach:

1. Gradually reduce homeowner tax incentives: Scaling back mortgage interest deductions would temper demand and help cool an overheated market.
2. Boost housing supply and rental sector investment: Streamlining permitting processes, loosening land-use restrictions, and phasing out bans on buy-to-let properties would encourage both institutional and private investors to expand the rental stock.

By establishing a clear timeline for reform, the Netherlands can provide certainty to homeowners, developers, and investors, enabling a smoother transition towards a more balanced housing system.

Government Initiatives to Enhance Supply

Dutch authorities have already signaled commitments to improve supply:

• Municipal incentives: From 2026, municipalities will receive financial rewards for every affordable home they construct, encouraging local governments to prioritize mixed-income projects.
• Relaxed building regulations: Adjustments to zoning and environmental requirements aim to fast-track cost-effective housing developments, lowering construction costs and delivery times.

These measures, combined with planned reductions in tax relief for owners, could help close the affordability gap and ensure a healthier mix of rental and owner-occupied homes.

What Renters and Landlords Should Know

For tenants, a stronger rental sector means greater choice and potentially more stable rents in the long run. As restrictions on private landlords ease, new investment is likely to increase the available stock, reducing competition for regulated units.

Landlords should prepare for a gradual shift:

• Anticipate evolving regulations around buy-to-let ownership and possible changes to rent-control frameworks.
• Stay informed about new financing models and government incentives that may support purpose-built rental developments.
• Focus on professional property management standards to appeal to a growing pool of quality-seeking tenants.

By adapting early, landlords can position themselves to benefit from a revitalized private rental market.

Looking Ahead: Balancing Ownership and Rent

The OECD’s findings highlight a critical juncture for Dutch housing policy. Maintaining generous homeowner tax relief indefinitely risks overheating prices further and leaving renters behind. Conversely, neglecting the desire for homeownership could stifle personal wealth building and consumer confidence.

A measured approach—gradually reducing mortgage interest deductions, accelerating new construction, and fostering a competitive private rental sector—offers a path to more stable, inclusive housing outcomes. Collaboration between national government, municipal authorities, developers, and market participants will be essential to implement these reforms effectively.
