Allowances (toeslagen) and your fluctuating freelance income

As a freelancer, your right to healthcare allowance (zorgtoeslag) and housing allowance (huurtoeslag) hinges on a single number: your toetsingsinkomen—the income the tax office uses to judge whether you qualify. Unlike a salaried employee with a fixed monthly pay slip, your profit swings year to year, which means your allowance estimate must be refreshed constantly. Get it wrong and you'll face a painful repayment demand when the Belastingdienst corrects it. This guide shows you how to estimate your toetsingsinkomen accurately and navigate the unique allowance risks that come with self-employment.

What is toetsingsinkomen and how does it affect your allowances?#

Your toetsingsinkomen is your verzamelinkomen—roughly, all forms of income the Belastingdienst counts when deciding whether you're entitled to allowances. For a freelancer, this includes:

Both zorgtoeslag (healthcare allowance) and huurtoeslag (housing allowance) use the same toetsingsinkomen threshold:

• Below a certain threshold (around €35,000–€37,000 for a single person in 2025/2026, hedge exact amounts), you qualify for one or both.
• Above it, you get no allowance.

The thresholds move annually, so check toeslagen.nl for your year's exact limits.

The danger: underestimating your profit#

Here's the catch that trips up most freelancers: you must declare your estimated toetsingsinkomen before you know what your actual profit is. Most freelancers do this in January or February, forecasting the coming year's income based on:

• Last year's actuals
• Current projects and rates
• Seasonal patterns
• Market conditions

How to estimate your toetsingsinkomen#

The goal: be as accurate as possible before the year starts, then revisit your estimate if conditions change mid-year.

Start with last year's actuals#

Look at your previous year's profit from your tax return. If your business was stable, a simple rule of thumb is:

This year's forecast ≈ Last year's profit ± expected growth/decline

For example:

• Last year: €28,000 profit
• This year: Expect one new client and higher rates → forecast €32,000
• You'd declare a toetsingsinkomen of around €32,000 (plus any employment income)

Account for big changes#

If a major client left or joined, if you're ramping up, or if the economy looks different, adjust. A few questions to ask yourself:

• How many billable hours do I expect?
• What's my average hourly rate?
• Will I have new clients or lose any?
• Are costs rising (software, rent, equipment)?

Calculate: (expected billable hours) × (average rate) – (expected costs) = rough profit forecast

Remember: deductions reduce your toetsingsinkomen#

Your toetsingsinkomen uses your profit after entrepreneur deductions (zelfstandigenaftrek, startersaftrek, MKB profit exemption). So:

1. Estimate gross profit (revenue – direct business costs)
2. Subtract your deductions (check this guide for the full picture)
3. The result is roughly your toetsingsinkomen

Update mid-year if things change#

If in June you realize your profit will be significantly higher or lower than your February forecast, contact the SVB and update your estimate. This is crucial. You can adjust your declared toetsingsinkomen at any time in the same calendar year.

The repayment trap: a worked example#

You forecast €28,000 profit and are approved for zorgtoeslag. The monthly allowance is €150. Over the year, you receive €1,800.

Then your year ends stronger than expected. You actually made €35,500 profit — well above the threshold. The SVB reviews your tax return and sees you were not entitled to any allowance for the parts of the year when your income exceeded the limit.

They demand repayment: potentially the entire €1,800 in a single bill. If you had updated your estimate mid-year, you would have received a smaller (or zero) allowance during the high-income months, and the final bill would be manageable or zero.

When you earn below the threshold — the good year and bad year cycle#

Many freelancers find a rhythm where some years dip below the threshold and others exceed it.

• A low-income year: You update your estimate downward and gain or regain allowance eligibility. The monthly top-up to your budget is welcome.
• A high-income year: You are above the threshold and receive no allowance. Plan for this by setting aside the money you'd otherwise get (see how much to reserve for tax).

The key is not to count on the allowance if your income is volatile. Treat it as a bonus in lean years, not a guaranteed part of your income.

Special case: starting from a benefit (WW or bijstand)#

If you're starting as a freelancer while on a WW or bijstand benefit, the allowance calculation is more complex because the benefit income counts in your toetsingsinkomen, and the benefit tapers as your business profit grows. See starting a business from benefits for the full story.

Frequently asked questions#

Your allowance eligibility is a moving target as a freelancer, but staying on top of your forecast each year keeps you out of trouble. The moment you sense your profit will be significantly different from what you declared, contact the SVB and adjust. That one phone call can save you hundreds or thousands in unwanted repayment surprises. And when you're in a lean year, the allowance can be a real lifeline—but never count on it if your income is uncertain.
