How Much Tax Should I Save as a Freelancer? [2025 Calculator]

One of the biggest pitfalls for freelancers: not setting aside enough money for taxes. This guide helps you avoid nasty surprises.

As a Dutch freelancer (ZZP'er), you don't get a payslip showing how much tax has already been withheld. You need to smartly save for taxes yourself. But how much exactly? In this article you'll find a practical calculator, specific percentages per income level, and smart monthly saving strategies.

The Golden Rule: Start With 30-40%

Let's start with the rule of thumb every Dutch freelancer should know: set aside 30-40% of your revenue for taxes as standard. This sounds like a lot, but remember this doesn't just include income tax, but also:

• Income tax (the largest part)
• Income-dependent contribution Health Insurance Act (5.26% in 2025)
• Potential additional assessments or setbacks

"But I have deductions, right?" I hear you thinking. Correct! That's why we'll now dive deeper into the exact percentages per situation.

Smart Percentage Guidelines per Income Level

Based on our calculations, we arrive at these useful savings percentages:

Monthly Saving Strategies That Work

1. The Separate Account Method

Open a separate savings account specifically for taxes. As soon as an invoice is paid:

1. Immediately transfer the tax percentage to this account
2. Treat this money as "not yours"
3. Set up an automatic transfer if possible

Many financial advisors recommend having two business accounts: one for operational matters and one for tax reserves.

2. The Provisional Assessment Tactic

Request a provisional assessment through the Dutch Tax Authority:

• You pay automatically monthly
• No large amounts afterwards
• You can adjust the amount mid-year
• Check our 2025 tax calendar for all payment deadlines

Tip: Rather request 10% too much than too little. Overpayments are refunded, underpayments cost you interest!

3. The 50/30/20 Rule for Freelancers

Adapt the classic budget rule for entrepreneurs:

• 50% for personal expenses (from your personal account)
• 30% for tax reserves
• 20% for business investments and buffer

When Can You Save Less?

There are situations where you can safely save less:

1. Combination with Employment

Do you work part-time as an employee alongside your freelance work? Then tax has already been withheld on your salary. You can often manage with 20-25% reserves on your freelance income.

2. Partner with High Income

Do you have a partner with a good salary and few deductions? Then consider fiscal partnership. You can divide certain deductions between yourselves. Read our fiscal partnership guide for smart strategies.

3. Many Investments Planned

Planning major investments? The small-scale investment deduction can amount to up to 28% of the investment amount.

Practical Calculator: Your Personal Percentage

Use this quick formula for your situation. Also check our gross to net calculator 2025 for a detailed breakdown:

Base percentage (see table)
+ 5% for Health Insurance Act
+ 5% for buffer/unforeseen
- 5% if you have many business expenses (>30%)
- 5% if your partner earns
= Your savings percentage

Common Pitfalls

Another common mistake is confusing revenue with profit.

And don't forget: income tax is not the only levy you face.
