💶 Do you earn extra income? For example, as a nanny, mail carrier, or tutor? Do you take on occasional freelance jobs—baking cakes, giving guest lectures, taking photos or videos on request? All of this can be profitable.

In this case, your income is considered income from other work (inkomsten uit overige werkzaamheden).
It is important to remember that even one-time part-time jobs can result in tax liabilities.

🧾 How to declare such income

Additional income must be indicated in tax return (Box 1).
Profit is calculated in the same way as for entrepreneurs: you can deduct part of the expenses associated with this activity (for example, transport, materials, equipment).

💰 Additional obligations

In addition to income tax, you also pay social security contributions (ZVW)After filing your tax return, you will receive a separate calculation from the Belastingdienst for this contribution.

💡 Working part-time is a great way to increase your income, but it's important to follow tax rules to avoid penalties and additional payments.
