A 15-Year Phase-Out: How Scrapping Mortgage Interest Deduction Can Be Managed Smoothly

A 15-Year Phase-Out: How Scrapping Mortgage Interest Deduction Can Be Managed Smoothly

The debate over the mortgage interest deduction (MID) in the Netherlands has intensified as political parties and financial experts weigh its long-term effects on housing affordability and market stability. Abolishing or scaling back this tax benefit may seem daunting to homeowners, especially first-time buyers, but experts argue that a gradual, 15-year phase-out can soften the blow—and even benefit the broader market in the long run.

What Is the Mortgage Interest Deduction?

The mortgage interest deduction allows Dutch homeowners to deduct the interest paid on their mortgage from their taxable income. Introduced in the 1980s to boost homeownership, MID has since become one of the largest tax expenditures in the Dutch budget. While the scheme supports homeowners, critics say it disproportionately benefits higher earners, fuels house price inflation, and crowds out other housing solutions such as rental properties.

Why Lawmakers Are Rethinking MID

Several parties, including GroenLinks–PvdA and the CDA, have included plans to reduce or eliminate the MID in their election manifestos. Their rationale is three-fold:

1. Fairness in taxation: MID primarily supports higher-income households with larger mortgages.
2. Price control: By making homeownership more expensive, the deduction can inflate property values.
3. Budgetary relief: Phasing out MID would free up billions in public funds for social housing, infrastructure, and sustainability projects.

Nonetheless, a sudden removal could shock household budgets, undermine consumer confidence, and destabilise the housing market.

Expert Proposal: A 15-Year Phase-Out

Mortgage expert Thomas de Leeuw of Frits Hypotheken and financial services provider Van Bruggen advocate for a gradual reduction of the deduction over 15 years. Their analysis uses an average annuity mortgage of €363,000—typical for first-time buyers in 2025—to model payment changes.

• Under current rules, the net monthly payment starts at €1,255 in year one and rises to €1,338 by year ten.
• With the deduction phased out linearly, the year-ten payment would be €1,560—an extra €222 over ten years, or roughly €20 per month.

De Leeuw points out that average incomes in the Netherlands grow by about 3% annually thanks to inflation and wage increases. This growth naturally offsets much of the incremental mortgage costs. Spreading the adjustment over 180 months gives households time to adapt and budget accordingly.

Mitigating Market Risks

One key risk arises if MID disappears in tandem with falling house prices. A market slowdown—already evident in pockets like Amsterdam—could leave some buyers “underwater” by as much as €50,000. A drawn-out phase-out reduces the chance that both events coincide, thus averting severe financial distress for recent homeowners.

Moreover, a transparent, long-term plan instills confidence in banks, investors, and buyers. Certainty about tax changes can prevent sudden shifts in lending criteria or interest rate shocks.

Wider Benefits of Ending MID

Longer term, phasing out mortgage interest deduction could yield several advantages:

• Greater tax equity: Removing a benefit that largely accrues to wealthier households promotes a fairer system.
• Reduced price inflation: Without a built-in subsidy, house prices may stabilize, improving affordability for both buyers and renters.
• Reallocation of funds: Government savings can bolster the woningcorporatie (social housing corporations) and expand huurtoeslag (rent allowance) programmes.

These measures support not only aspiring homeowners but also renters and low-income families seeking stable housing.

Planning for Homebuyers and Renters

If you’re saving for a home or already have a mortgage, consider the following steps:

1. Budget conservatively: Factor in a gradual rise in your monthly mortgage outlay of up to €20 per month over a decade.
2. Lock in a fixed rate: A long-term fixed interest rate can shield you from market volatilities.
3. Monitor policy updates: Keep an eye on government announcements and election developments to anticipate any changes in the phase-out timeline.
4. Explore rental options: If you prefer flexibility or want to avoid long-term commitments, renting may be a better short-term solution.

Conclusion

Phasing out the mortgage interest deduction is arguably inevitable in the Netherlands’ pursuit of a fairer and more stable housing market. By adopting a 15-year transition, policymakers can minimise financial shocks, reduce systemic risks, and redirect public funds toward affordable housing initiatives. Homebuyers, especially first-timers, will have time to adjust their budgets and make informed financing decisions.
