Result from Other Activities vs Business Profit

Published
Updated
ByJolande Geerts

Short answer

Not every paid activity is automatically a business for Dutch income tax. Belastingdienst says income from other work must also be reported in the tax return, and some costs can be deducted, but you do not get the normal entrepreneur facilities such as the zelfstandigenaftrek or investment allowance. By contrast, if your activities qualify as winst uit onderneming (business profit), you enter the business-profit lane instead. The difficult part is that being registered somewhere, or even having VAT duties, does not settle the income-tax question by itself.

Who this article is for

This page is for:

  • expats doing freelance work next to employment
  • people with project income, advisory fees or occasional paid assignments
  • starters unsure whether they are already “real entrepreneurs” for income tax
  • readers who want to know why VAT and income-tax treatment can differ

What “result from other activities” means

Belastingdienst’s Dutch page on income from other work explains the core rule clearly: if you earn money outside employment and you are not an entrepreneur for income tax, that income may still be taxable as inkomsten uit overig werk or resultaat uit overige werkzaamheden.

Two important consequences follow from that page:

  • you must still report the income in the tax return
  • some costs linked to that work may still be deductible

So this is not an informal grey zone. It is a real taxable category.

What it is not

It is not the same as being an entrepreneur for income tax.

Belastingdienst’s entrepreneur page says that not every entrepreneur is automatically an entrepreneur for income tax. The tax authority looks at factors such as:

  • whether you participate in economic traffic
  • whether you work outside the private sphere
  • whether profit can reasonably be expected

That means the business-profit question is broader than “did I send an invoice?”

The practical difference in tax consequences

If your income is result from other activities

Belastingdienst says your profit is calculated broadly like that of entrepreneurs, and some costs are deductible. But you do not get certain entrepreneur-specific reliefs such as:

  • the zelfstandigenaftrek
  • the investment allowance

Belastingdienst also says that, besides income tax, you pay an income-related Zvw contribution, for which you receive a separate assessment after filing.

If your income is business profit

Then you are in the entrepreneur-for-income-tax lane, with its own reporting duties and potentially broader entrepreneur facilities, depending on the full facts.

Why this distinction matters so much for expats

Expats often get mixed signals from three places at once:

  • they register with KVK
  • they receive or expect a VAT number
  • they assume that means they are fully an entrepreneur for income tax

That is risky.

The Dutch system does not always move in one line. You can have activity that is taxable, that may create VAT consequences, and that still does not automatically become business profit for income tax.

A useful decision path

Ask these questions in order.

1. Is there a real source of income?

Are you doing paid activities outside your private life and can you expect profit? If not, the starting point may be hobby or private activity rather than taxable work.

2. If there is taxable activity, are you actually an entrepreneur for income tax?

That is the business-profit question. Look at the full factual picture, not one single label.

3. If not, is the income still taxable as result from other activities?

Often the answer is yes.

The VAT mismatch problem

This is one of the most important clarifications in the whole topic.

Someone can have VAT obligations and still not be an entrepreneur for income tax in the same way. That is why this article should be read together with the ZZP/VAT page.

Do not use one of these as proof of the other:

  • KVK registration
  • a VAT number
  • the fact that clients call you “self-employed”
  • the fact that you only have one client

Each of those may be relevant, but none of them is the whole tax answer.

What to keep in your file

If you are near the border between the two categories, keep a very clean record of:

  • the nature of the work
  • frequency and continuity
  • number of clients
  • turnover and profit expectation
  • contracts and invoices
  • costs directly linked to the work

That documentation helps whether the final answer is “other activities” or “business profit”.

Common mistakes

  • assuming all invoiced work is automatically business profit
  • missing the fact that result from other activities is still taxable
  • deducting entrepreneur facilities that do not apply
  • ignoring the separate Zvw contribution consequence
  • using VAT status as if it fully settles the income-tax analysis

What to do now

  1. Decide whether the activity is a real taxable source of income.
  2. Test separately whether you are an entrepreneur for income tax.
  3. If not, report the income as result from other activities and only deduct costs that actually belong there.
  4. Review the ZZP/VAT page separately if you also invoice clients or have VAT questions.
