Renting Out Your Property: Box 1 vs. Box 3 Implications

Key Takeaways

Your primary residence (eigen woning) is taxed in Box 1. When you rent it out, it generally moves to Box 3 — with major tax consequences.
In Box 3, you lose the mortgage interest deduction and pay tax on the property's deemed return based on its WOZ value.
Temporary rental of your primary residence (e.g., through Airbnb) has special rules and may keep the property in Box 1.
A property you buy specifically to rent out is always in Box 3 and subject to 10.4% transfer tax.
Rental income itself is not directly taxed in Box 3 — the tax is on the deemed return on the asset value.

The Fundamental Distinction

The Dutch tax system draws a sharp line between the home you live in and property you rent out:

	Your Own Home (Eigen Woning)	Rental Property (Verhuurd)
Tax box	Box 1	Box 3
Income taxed	Eigenwoningforfait (tiny %)	Deemed return on WOZ value
Mortgage interest	Deductible	NOT deductible
Actual rental income	Not applicable	Not separately taxed (covered by Box 3 deemed return)
Transfer tax at purchase	0% or 2%	10.4%

This distinction has enormous financial implications. Let's explore each scenario.

Scenario 1: You Buy a Property to Rent Out

If you purchase a property with the intention of renting it out, it goes directly into Box 3:

How It Is Taxed

In Box 3, the property is taxed on a deemed return (forfaitair rendement), not on actual rental income:

The property's WOZ value is included in your Box 3 assets (on January 1)
Any mortgage on the property is included as a Box 3 debt (only the amount exceeding the threshold of €3,700 per person in 2026)
The net value is assigned a deemed return rate based on asset composition
The deemed return is taxed at a flat 36% (2026)

Example:

Property WOZ value: €350,000
Mortgage: €280,000
Net Box 3 value: €70,000 (after debt threshold)
Deemed return (2026 rate for real estate category): approximately 6.04% → €4,228
Tax at 36%: €1,522

Meanwhile, your actual rental income might be €15,000/year — but it is not separately taxed. The deemed return system assumes your assets generate a certain return, regardless of actual income.

Good to know

The Box 3 system has been in flux. Following the 2021 Kerstarrest (Supreme Court ruling that the old deemed return system was potentially discriminatory), the government introduced a new method that uses separate deemed return rates for different asset categories (savings, investments, real estate, debts). The rates are adjusted annually to better reflect actual market returns.

Additional Costs

Transfer tax: 10.4% at purchase
Income tax (Box 3): Based on deemed return, regardless of actual rental income
Municipal taxes: OZB, rioolheffing (as property owner)
Maintenance: Fully at your expense (not tax-deductible in Box 3)
Landlord obligations: Dutch tenant protection laws are very strong — eviction is extremely difficult

Scenario 2: You Move Out and Rent Out Your Eigen Woning

A common situation: you relocate (domestically or abroad) and want to rent out the home you used to live in.

The General Rule

When you stop living in a property, it ceases to be your eigen woning and moves from Box 1 to Box 3. You lose the mortgage interest deduction immediately.

The Relocation Exception (Verhuisregeling)

There is an important exception for people trying to sell their home. If you move out but cannot sell:

The property stays in Box 1 for up to 3 years after you leave
You keep the mortgage interest deduction during this period
The eigenwoningforfait still applies
After 3 years, it moves to Box 3

Conditions:

The property must be available for sale or empty (this was relaxed — temporary rental may be allowed under certain conditions)
You must have moved to a new primary residence

Warning

If you rent out your old home during the 3-year period, it may still move to Box 3 immediately — the verhuisregeling was traditionally for empty properties awaiting sale. However, in practice, temporary rental while actively selling is sometimes accepted. Consult your tax advisor for your specific situation, as the rules have nuances.

Temporary Expat Assignment

If you are temporarily posted abroad and plan to return:

Short assignment (up to ~2 years with return intention): you may keep the property in Box 1, especially if it remains available for your return and is not rented out
Long assignment or permanent move: the property generally moves to Box 3
If you rent it out during the assignment: Box 3 in most cases

Scenario 3: Renting a Room in Your Own Home (Kamerverhuur)

If you rent out a room in the home you live in (not the entire property), the kamerverhuurvrijstelling (room rental exemption) may apply:

Conditions

You rent out a room or rooms in the property where you live (it remains your eigen woning)
The total rental income is below €5,881 per year (2026)
The rented space is part of the property (not a separate unit)

Tax Treatment

If you meet the conditions:

The rental income is tax-free
The property stays in Box 1
You keep your mortgage interest deduction
No additional eigenwoningforfait or Box 3 taxation

If you exceed the €5,881 threshold:

The rental income is added to your Box 1 income as income from the eigen woning
The property may partially or fully shift to Box 3 depending on the circumstances

Tip

The kamerverhuurvrijstelling is an attractive option if you have a spare room. Tax-free income of nearly €6,000 per year with no impact on your mortgage deduction — as long as you stay below the threshold and the renter lives in your home.

Scenario 4: Short-Term Rental (Airbnb)

Renting your home or a room through platforms like Airbnb has specific implications:

Your Entire Home (While You Are Away)

If you occasionally rent your entire home (e.g., during holidays) for a short period, it may remain in Box 1 — the property is still your primary residence
The rental income should be reported, but the kamerverhuurvrijstelling may apply if the amounts are modest
If the rental is frequent and structural, the Belastingdienst may argue it is a commercial activity — potentially creating a VAT obligation and Box 1 business income

A Separate Unit or Room

If you rent a separate unit (e.g., a studio in your garden), it is generally treated as a separate property in Box 3
If you rent a room within your home, the kamerverhuurvrijstelling applies (below the threshold)

Municipal Rules

Many municipalities (especially Amsterdam, Rotterdam, Utrecht) have strict regulations on short-term rental:

Maximum number of rental nights per year (often 30 in Amsterdam)
Registration requirements
Fire safety requirements
Tourist tax (toeristenbelasting)
Fines for non-compliance can be €20,000+

Financial Comparison

To illustrate the impact, here is a comparison for a property worth €400,000 with a €300,000 mortgage at 4% interest:

	Box 1 (Eigen Woning)	Box 3 (Rental Property)
Eigenwoningforfait	+€1,400	Not applicable
Mortgage interest deduction	−€12,000	Not applicable
Net eigen woning income	−€10,600	—
Tax saving (Box 1)	~€3,919	—

Box 3 asset value	—	€400,000
Box 3 debt	—	−€296,300 (after threshold)
Net Box 3 value	—	€103,700
Deemed return (~6%)	—	~€6,222
Tax cost (Box 3, 36%)	—	~€2,240

Total annual tax impact	−€3,919 (benefit)	+€2,240 (cost)
Difference		€6,159/year worse in Box 3

Moving from Box 1 to Box 3 costs approximately €6,159 per year in this example — and that is before considering the actual rental income (which is not taxed separately in Box 3, but you lose the mortgage deduction benefit).

Common Mistakes

Renting out your home without understanding the Box shift — The move from Box 1 to Box 3 costs thousands per year in lost tax benefits.
Assuming rental income is tax-free in Box 3 — While actual rent is not separately taxed, the deemed return tax on the property value applies regardless.
Exceeding the kamerverhuurvrijstelling threshold — Going even €1 above €5,881 changes the tax treatment. Track your rental income carefully.
Ignoring municipal short-term rental rules — Fines for illegal Airbnb rental are steep and enforced, especially in major cities.
Not recalculating after life changes — If you separate from a partner, move abroad, or inherit a property, the Box 1/Box 3 classification may change. Review your tax position.
Forgetting the 10.4% transfer tax — If you buy a property specifically to rent out, the higher transfer tax rate applies from day one.
