As an expat considering buying property in the Netherlands, you have probably heard the term hypotheekrenteaftrek (HRA), or Mortgage Interest Deduction (MID). This fiscal benefit is often hailed as a key advantage of homeownership. However, it is anything but simple. In fact, the HRA is one of the most debated and rapidly changing elements of the Dutch tax system.

ExpatEstate understands that this uncertainty causes significant anxiety for potential buyers. Is the hypotheekrenteaftrek here to stay? What do proposed changes mean for your long-term financial stability? We will break down this complex system, offering clear insights into the current regulations and the most likely scenarios for reform.

Defining the Hypotheekrenteaftrek (HRA/MID)

The hypotheekrenteaftrek allows homeowners to deduct the interest paid on their primary residence mortgage (the “own home debt”) from their taxable income in Box 1. Essentially, the HRA acts as a government subsidy designed to promote homeownership.

To truly understand this benefit, we must also consider the Eigenwoningforfait (Imputed Rental Value). The Dutch government views the enjoyment of living in your own home as a form of taxable income in kind. Therefore, homeowners must add a small, fictional amount (a percentage of the property’s WOZ value) back into their Box 1 taxable income.

The Net Benefit: Typically, the interest deducted (HRA) is higher than the imputed income (Eigenwoningforfait). Consequently, the HRA results in a net tax advantage. However, policymakers have continuously introduced stricter conditions to curb this subsidy over the past two decades.

The Evolution of Complexity: Three Major Restrictions

The ‘own home’ regime has become increasingly complex. What started as a straightforward deduction now requires meticulous financial tracking.

1. The 30-Year Limit (Since 2001)

To prevent the subsidy from running indefinitely, the government imposed a time limit. You can only deduct mortgage interest for a maximum of 30 years.

A Crucial Deadline: This means that for older loans taken out before 2001, the deduction right will expire in 2031. Many homeowners who opted for interest-only mortgages during that period face a looming financial cliff edge. They must now consider how to pay off the principal before the deduction is completely lost.

2. The Debt Limitation Rule (Bijleenregeling, Since 2004)

If you sell your current home for a profit (overvalue), you are subject to the Bijleenregeling. This rule mandates that you must use that overvalue (known as the ‘Own Home Reserve’) toward purchasing your next house.

In essence, if you do not reinvest this overvalue, you lose the right to deduct interest on that specific portion of the new loan. This measure prevents homeowners from cashing out equity while continuing to benefit from the HRA on a larger new mortgage.

3. Mandatory Amortization (Since 2013)

Following the 2008 financial crisis, there was an intense focus on reducing high household debt in the Netherlands. Consequently, as of 2013, new mortgages must meet strict repayment rules.

New loans must be fully amortized (paid off) within a maximum of 30 years using a linear or annuity repayment schedule. Therefore, if you fail to adhere to the agreed-upon repayment plan, you forfeit the right to claim the hypotheekrenteaftrek. This requirement has significantly complicated the administration of moving houses, as buyers must now track their exact amortization status alongside their Own Home Reserve.

Political Pressure: Moving the Home to Box 3?

The Dutch Mortgage Interest Deduction faces substantial criticism both domestically and internationally. Organizations like the International Monetary Fund (IMF), the European Commission, and the Dutch Central Bank (DNB) argue that the HRA artificially inflates house prices and encourages excessive borrowing.

The Box 3 Discussion

One widely discussed proposal is moving the owner-occupied home from Box 1 (Income from Work and Home) to Box 3 (Savings and Investment). Proponents initially suggested this would dramatically simplify the system.

However, the process is complicated. Box 3 itself is currently under massive scrutiny and reform because it taxes fictional rather than actual returns. If the home moves to Box 3, experts believe the Eigenwoningforfait (fictional income) would likely move with it. In that scenario, you would pay Box 3 tax on the fictional income while still deducting actual mortgage interest. Aside from the tax rate, the fundamental structure remains complex, especially if new restrictions are added.

The Most Likely Outcome: Gradual Phase-Out

Experts widely agree that abolishing the HRA immediately is highly improbable. Immediate termination would cause massive financial hardship for current homeowners and could destabilize the housing market.

Consequently, the most realistic path forward is a gradual, controlled phase-out.

One key proposal suggested by the State Secretary of Fiscal Affairs recommends a 20-year linear phase-out, starting soon. This plan aims to eliminate the HRA completely by 2048 and resolves the administrative headache concerning the 2031 deadline.

Year	Deductible Percentage of Interest	Rationale
2028	100%	Full Deduction
2029	95%	Start of 5% annual reduction
2030	90%	Continued reduction
2040	40%	Significant reduction
2048	0%	Full deduction termination

This proposal offers clear long-term certainty for policymakers and gradual adjustment time for homeowners.

Practical Impact: Borrowing Power and House Prices

Uncertainty about the HRA often leads expats to ask two critical questions: Will house prices collapse? And can I borrow less?

Impact on House Prices

What would happen to property values if the HRA phased out? History offers some perspective. Between 2014 and 2024, the maximum deduction rate gradually dropped from over 50% to under 40%. Yet, house prices rose dramatically during this decade due to market shortages and low interest rates.

Ultimately, housing prices depend on a multitude of macroeconomic factors—not just one tax deduction. Experts suggest that a gradual phase-out is unlikely to cause a market crash.

Effect on Borrowing Capacity

If the HRA disappears, your net monthly housing costs will rise. Could this restrict how much you can borrow?

This depends heavily on whether the government introduces compensating measures. If the tax benefit is eliminated, the government may simultaneously lower income tax rates. Therefore, if your net income rises due to lower income tax, your maximum borrowing capacity might remain relatively stable, even without the deduction. Lenders rely on your net disposable income to calculate your maximum mortgage.

Key Actionable Advice for Expat Home Buyers

Given the looming reforms, expats must approach their Dutch mortgage with careful, future-proof planning.

1. Calculate Your Worst-Case Net Costs

Do not base your budget solely on the immediate, subsidized net monthly payment. Instead, calculate what your expenses would be without the deduction. Ensure your budget can comfortably handle this higher, unsubsidized monthly cost.

2. Seek Integrated Advice

The rules around the hypotheekrenteaftrek, the Bijleenregeling, and potential Box 3 transitions are highly integrated. Seek advice from a professional mortgage advisor who specializes in expat finances and can model your situation under various future scenarios.

3. Review Your Amortization Plan

If you have a mortgage taken out after 2013, ensure you strictly adhere to the mandatory repayment schedule. Failing to do so is the fastest way to lose your right to the hypotheekrenteaftrek entirely.

In conclusion, the hypotheekrenteaftrek remains a relevant, yet rapidly evolving, factor in Dutch homeownership. While the complete, immediate elimination of the benefit is unlikely, a structured phase-out is almost certain. By understanding this complexity and planning for lower net benefits in the future, you can make informed decisions and secure your financial foundation in the Netherlands.
