Toetsingsinkomen in the Netherlands: What It Is and How to Calculate It in 2026

If you've ever applied for huurtoeslag (rent subsidy), zorgtoeslag (health insurance subsidy), or kinderopvangtoeslag (childcare subsidy) in the Netherlands, you've encountered the term toetsingsinkomen. It's the single most important number for determining whether you qualify for Dutch government benefits — and how much you'll receive.

Yet many people don't fully understand what it is, how it's calculated, or what income sources count toward it. Getting it wrong can mean missing out on thousands of euros in benefits, or worse, facing a hefty repayment demand (terugvordering) later.

This guide explains everything you need to know about toetsingsinkomen in 2026.

What is toetsingsinkomen?

Toetsingsinkomen (literally "assessment income") is the income figure used by Dienst Toeslagen (the Dutch benefits agency) to determine your eligibility for government subsidies.

Think of it as the Dutch government's universal yardstick for means-tested benefits. Whether you're applying for rent subsidy, health insurance subsidy, childcare subsidy, or kindgebonden budget (child benefit), Dienst Toeslagen uses your toetsingsinkomen to decide:

• Whether you qualify at all
• How much you'll receive per month
• Whether you need to repay anything after the final assessment (definitieve berekening)

How is toetsingsinkomen calculated?

The calculation depends on whether you file a belastingaangifte (income tax return) or not.

If you file an income tax return

Your toetsingsinkomen = verzamelinkomen (aggregate income) from your definitieve aanslag inkomstenbelasting (final tax assessment).

Verzamelinkomen is the sum of income from all three Dutch tax boxes:

• Box 1: Income from work and home (salaries, pensions, benefits, eigenwoningforfait)
• Box 2: Income from substantial business interest (dividends from companies where you own ≥5%)
• Box 3: Income from savings and investments (wealth tax on assets above the tax-free threshold)

After deductions (aftrekposten) like hypotheekrenteaftrek (mortgage interest deduction), alimony, and certain specific costs, you get your verzamelinkomen. This is the number on your tax assessment under "verzamelinkomen" — and that's your toetsingsinkomen.

If you don't file a tax return

Your toetsingsinkomen = belastbaar loon (taxable wage) from your jaaropgaaf (annual salary statement).

Your jaaropgaaf shows the total amount subject to payroll tax (loonheffing). This is also called "fiscaal loon" or "bedrag voor de loonheffingen (LH/LB)". If you only have a single employer and no other income sources, this is straightforward — your employer sends the jaaropgaaf to both you and the Belastingdienst.

What income counts toward toetsingsinkomen?

The following do count:

• Salary (including company car — auto van de zaak)
• Freelance/self-employment income (winst uit onderneming)
• Benefits: WW (unemployment), bijstand (social welfare), ziektewet (sickness benefit)
• Pensions: AOW, bedrijfspensioen, foreign pensions
• Severance pay (ontslagvergoeding)
• Side income: freelance work, delivering newspapers, gastouder (childminding)
• Alimony for yourself (partneralimentatie) — not child alimony
• Rental income from your own home (if you rent out part of it)
• Foreign income (including foreign pensions, salaries, benefits)
• Internationally tax-exempt income (e.g., UN, EU, ICJ employee salaries)

What income does NOT count?

The following are excluded from toetsingsinkomen:

• Toeslagen themselves: zorgtoeslag, huurtoeslag, kinderopvangtoeslag, kindgebonden budget
• Kinderbijslag (child benefit)
• Studiefinanciering (student grants) and studieleningen (student loans)
• One-time study grants
• Alimony for your children (kinderalimentatie)
• Volunteer compensation (up to the legal threshold)
• Tegemoetkoming Arbeidsongeschikten (disability supplement, formerly Wtcg)
• Tax refunds (teruggaaf inkomstenbelasting)
• Persoonsgebonden budget (PGb) as a budget holder (but if you provide care paid from PGb, that income does count)
• Pleegzorgvergoeding (foster care allowance)

Estimating your toetsingsinkomen for the current year

When you apply for toeslagen for 2026, the year isn't over yet — so you don't have a final tax assessment. You must estimate your toetsingsinkomen.

Dienst Toeslagen will make an initial estimate based on your previous year's income (2025). But if your situation has changed — new job, salary increase, loss of income, partner change — you need to update this estimate.

How to estimate:

1. Look at your most recent loonstrook (payslip) or uitkeringsspecificatie (benefit statement)
2. Multiply your monthly gross income by 12 (or adjust for known changes — raises, bonuses, part-time hours)
3. Add any other income sources (freelance, rental, pension)
4. Subtract applicable aftrekposten (hypotheekrenteaftrek, etc.)
5. Report this estimate via Mijn Toeslagen or the Toeslagen app

The Belastingdienst provides an official tool to help estimate your toetsingsinkomen: Bereken uw toetsingsinkomen.

Why toetsingsinkomen matters so much

Your toetsingsinkomen directly affects:

• Zorgtoeslag: Up to €164/month (single) or €314/month (couples) in 2026 — totaling nearly €2,000-3,800/year
• Huurtoeslag: Up to €370/month depending on rent and household income — up to €4,440/year
• Kinderopvangtoeslag: Can cover 80-96% of childcare costs depending on income
• Kindgebonden budget: Quarterly payments for families with children

A difference of just €1,000 in reported income can mean hundreds of euros difference in annual benefits — or the difference between qualifying and not qualifying at all.

Common mistakes to avoid

1. Forgetting to include side income Freelance gigs, Uber driving, tutoring, Airbnb hosting — it all counts. If the Belastingdienst discovers unreported income later, you'll face a terugvordering (repayment demand) plus potential fines.

2. Using gross salary instead of belastbaar loon Your gross salary (bruto salaris) and belastbaar loon are not the same. Belastbaar loon is usually slightly lower after excluding certain reiskostenvergoeding (travel allowances) and other non-taxable benefits.

3. Not updating after a job change Started a new job mid-year? Got a raise? Lost hours? You must update your estimate. The initial calculation is based on last year — if this year looks different, update it.

4. Assuming toeslagen don't count Correct — but many people mistakenly think kinderbijslag does count. It doesn't. Neither do any of the four main toeslagen.

5. Ignoring your partner's income If you have a toeslagpartner (married, registered partnership, or living together with shared finances), their income is added to yours for all toeslagen calculations.

FAQ

What's the difference between toetsingsinkomen and verzamelinkomen?

If you file a tax return, they're the same thing. Toetsingsinkomen is the term Dienst Toeslagen uses; verzamelinkomen is the term on your tax assessment. Both refer to your total taxable income from all three boxes after deductions.

Do I need to include my partner's income?

Yes, if you have a toeslagpartner. This usually means you're married, in a registered partnership, or living together and sharing a household (finances). Their toetsingsinkomen is added to yours. For huurtoeslag, medebewoners (adult housemates) also count.

What if I work abroad but live in the Netherlands?

Foreign income counts. You'll need to report it using the Opgaaf wereldinkomen form that Dienst Toeslagen sends you each year. Your toetsingsinkomen includes worldwide income, not just Dutch sources.

When should I update my toetsingsinkomen estimate?

Anytime something significant changes: new job, salary increase/decrease, starting/stopping freelance work, partner change, losing benefits, starting a pension. Update via Mijn Toeslagen or the app. Dienst Toeslagen will recalculate within 5 weeks.

Can I use last year's income as this year's estimate?

Only if your situation is identical. If you expect your 2026 income to be similar to 2025, the Belastingdienst's automatic estimate (based on your 2025 data) will be close. But if anything has changed, you need to adjust it.
