Many people still don't know, but the tax you paid on your savings and investments in Box 3 was based on a fictitious return for years. That means: the tax authorities pretended to earn 4%, 5% or sometimes even more — while the real interest rate on your savings account was often below 1%. The result? For years, millions of Dutch people structurally paid too much tax.

The judge intervened: this method of levying is unlawful

In 2021, the Supreme Court ruled that this method is contrary to property law and the prohibition of discrimination. Since then, the entire Box 3 system has been called into question. The government has now set aside €10 billion to compensate people who unfairly paid too much tax between 2017 and 2022.

But note: you will not get this money back automatically. You have to take action yourself.

How do you know if you are entitled to a refund?

If you had assets in one or more years between 2017 and 2022 (savings, investments, a second home), you probably paid tax in Box 3. Whether you are entitled to a refund depends on:

• the amount of your actual return
  
  
• the fictitious rate of return that has been applied
  
  
• your total assets and debts
  
  
• how your assets were divided between savings, investments and other assets
  
  

For many people, the actual return is lower than the fictitious return. And it is precisely that difference that makes the claim possible.
