Amsterdam, Netherlands – Hundreds of thousands of Dutch homeowners could face significantly higher housing costs as the tax deduction for mortgage interest nears its end, a situation many are unaware of, according to reports surfacing Tuesday, March 3, 2026.
The tax benefit, which reduces the financial burden of mortgage interest payments, will commence to phase out starting in 2031. This change is expected to impact household budgets, particularly for those with variable or adjustable-rate mortgages, and could place downward pressure on housing affordability. Some homeowners may even be forced to sell their properties, experts warn.
A recent study by Van Bruggen Adviesgroep revealed that 56% of homeowners aged 40 to 67 with interest-only mortgages are unaware of when their mortgage interest tax deduction will expire. This lack of awareness poses a substantial risk, as the loss of this tax benefit could lead to unexpected increases in net mortgage costs and potential back payments.
“The tax benefit disappears, but the debt remains. At the same time, income often decreases upon retirement,” said Mark van Ginkel, a mortgage advisor at Van Bruggen. “Many people don’t realize this.”
The situation is further complicated by the fact that many homeowners do not recall the specifics of their original mortgage agreements, making it difficult to determine when the 30-year deduction period began. The rules surrounding mortgage interest relief have evolved over time, particularly for new interest-only loans since 2013, adding to the confusion.
According to Van Bruggen, the urgency is high. The current regulations, stemming from the Income Tax Act of 2001, allow for a maximum of 30 years of mortgage interest deductibility. As the first wave of homeowners reaches the end of this period in January 2031, the impact on household finances will become increasingly apparent.
Homeowners are advised to take proactive steps to mitigate the impact, including increasing mortgage repayments, switching from interest-only to principal and interest repayment plans, refinancing to secure more favorable rates, or adjusting their budgets. Seeking advice from a mortgage advisor or the tax authorities is also recommended to explore available options and transition arrangements.
The potential for increased financial strain on homeowners underscores the importance of financial planning and awareness of evolving tax regulations. The situation highlights the need for clear communication from lenders and the tax authorities to ensure homeowners are prepared for these changes.
