ZZP Tax Return 2025: All Deductions at a Glance

March is approaching again, time for the annual tax return. As a freelancer (ZZP), you are entitled to numerous deductions that can significantly reduce your tax burden. But which ones exactly? And more importantly: which ones might you forget? In this article, we list ALL deductions for freelancers, complete with examples and required documentation.

Top 10 Deductions Every Freelancer Must Know

1. Self-employed Deduction: The Most Important for 2025

The self-employed deduction is the largest deduction for most freelancers.

Practical example:
Sandra is a freelance copywriter. She works 30 hours per week, 46 weeks per year = 1,380 hours. She meets the hour criterion and may deduct € 2,470 from her profit.

Required documentation:

• A time tracking app provides a complete hour registration that you can use as proof for your tax return.
• Proof of entrepreneurship (Chamber of Commerce extract)

2. Starter Deduction: Extra Benefit for Beginners

Did you recently start? Then you may be entitled to the starter deduction. Read our complete guide to the starter and self-employed deduction for all details.

Practical example:
Tom started in July 2023 as a freelance developer. In 2025, he may use the starter deduction for the third and final time. Total benefit over 3 years: € 6,369!

3. SME Profit Exemption: For Everyone

The SME profit exemption applies to ALL entrepreneurs, even without hour criterion.

Calculation example:

Profit: € 50,000

SME profit exemption: 12.70% x € 47,530 = € 6,036

Invest smartly:

• Just above € 2,901 for KIA
• In December for immediate deduction next year
• Spread over years when phasing out self-employed deduction
