How Does the 30% Ruling Affect Your Expat Mortgage in the Netherlands?

The 30% ruling mortgage impact catches many new expats off guard: the tax break boosts your monthly take-home pay, but it rarely changes the maximum mortgage a Dutch lender is willing to give you. Most banks in the Netherlands calculate your borrowing capacity from your full gross salary, not from the reduced taxable portion the 30% ruling creates. That difference between net benefit and gross-based lending is the first thing to understand before you start house hunting.

How does the 30% ruling actually affect your income?

If you qualify for the 30% ruling, your employer can pay up to 30 percent of your salary tax-free, treating that portion as a reimbursement for the extra costs of working abroad rather than as taxable income. In 2026, the percentage is still 30 percent, and the benefit runs for a maximum of five years. To qualify you generally need to be recruited from abroad, bring specific expertise that is scarce in the Dutch labour market, and earn above a minimum salary threshold, roughly 48,000 euros gross in 2026 for most applicants, with a lower threshold for younger graduates.

The ruling is tied to an employment relationship, so it only works through payroll. If you work as a sole trader (eenmanszaak) rather than through a company, you cannot use the 30% ruling or the related tax-free reimbursement of actual extraterritorial costs, because both are employer-based schemes. If you are a director-shareholder (DGA) paid through your own BV, you can still qualify for the ruling, as long as you meet the usual conditions around recruitment from abroad, expertise and salary.

Does the 30% ruling mortgage benefit increase how much you can borrow?

Picture an expat earning 100,000 euros gross plus the 30% ruling, house hunting for a property priced around 800,000 euros. It is tempting to assume the tax-free portion stretches your budget, but most lenders build their calculation on the full gross salary as if it were entirely taxable, so the ruling mainly lifts your net income rather than the mortgage amount you qualify for.

Some lenders do take the ruling into account when assessing what you can afford, but they typically stress-test the mortgage against your income for the years after the ruling ends. That means your maximum mortgage is often closer to what your salary alone supports, not what your current, higher net income might suggest.

Where you can genuinely gain ground is through structural allowances on top of your base salary, such as housing or relocation allowances, since many lenders will count these as qualifying income if they are documented in your employment contract or employer statement. Lenders differ a lot in which allowances they accept and how heavily they weigh them, so the choice of lender matters more for your maximum mortgage than the 30% ruling itself.

What happens to your mortgage when the ruling ends?

The 30% ruling has a fixed end date, and lenders know it. Because your net income drops once the tax-free portion disappears, most mortgage assessments already factor in your income as if the ruling had ended, so in principle your monthly payment should not suddenly become unaffordable when that day arrives.

In practice, though, many expats build their lifestyle around the higher net income the ruling provides. It is worth running the numbers for the years after the ruling stops, including how your monthly mortgage payment compares to your net salary once you are taxed on your full income, so there are no surprises down the line.

How does the 2027 change to the 30% ruling mortgage rules affect your planning?

From 1 January 2027, the maximum tax-free percentage under the ruling drops from 30 to 27 percent, but only for employees whose ruling first applied in 2024 or later. If your ruling started on or before 31 December 2023, you keep the full 30 percent for the rest of your ruling’s term under a transitional arrangement.

For a mortgage, this mainly matters for how you plan your monthly budget over the coming years rather than for the maximum amount a bank will lend you today, since the borrowing calculation is already based on gross income in most cases. If your ruling falls under the new 27 percent bracket from 2027, your net income will drop a little earlier than someone under the transitional arrangement, so build that into your long-term budget rather than only into the mortgage application itself.

Which mortgage structure works best with a time-limited tax benefit?

A linear mortgage, where you repay a fixed amount of the principal every month and the interest portion shrinks over time, is often a sensible fit if you want to use the higher net income from the ruling to build equity faster while it lasts. Combined with a longer fixed-rate period, for example 20 years, your monthly payment stays predictable well beyond the point where the ruling ends.

In 2026, you can still finance up to 100 percent of the purchase price through a Dutch mortgage, or up to 106 percent if part of the extra amount goes toward energy-saving measures such as insulation or a heat pump. The rate you are tested against, the toetsrente, sits around 5 percent in 2026 for fixed periods under 10 years, while longer fixed periods use the actual contracted rate, which is currently between 3.5 and 4.5 percent, for the affordability test.

On top of the mortgage itself, budget for kosten koper (purchase costs), typically 3 to 6 percent of the purchase price in 2026, covering things like valuation, notary fees and advisory costs. Advisory fees, the valuation and the notary fee for the mortgage deed are tax-deductible in your Box 1 return, while transfer tax and estate agent fees are not, so it is worth knowing which costs actually lower your tax bill and which do not.

If your mortgage stays under the 2026 NHG limit of 470,000 euros, or 498,200 euros when you include qualifying energy measures, you may also qualify for the Nationale Hypotheek Garantie, a government-backed safety net that often comes with a lower interest rate. Because every lender treats the ruling, allowances and post-ruling stress tests differently, it helps to compare scenarios with an experienced advisory team before you commit to one bank. You can also schedule a no-obligation conversation to map out your specific numbers before you start bidding on a home.
