FAQ
Belgium - Tax Return

You need the following documents to file your tax return:

• a certificate of taxable income - Fiche,
• additional Fiche forms if you have other sources of income other than employment (pension, unemployment benefits, author's fee, etc.),
• EWR, that documents local income from your home country,
• ID / passport,
• other documents for claiming rebates (child's birth certificate, etc.).

Fiche 218.10 form is a form that every employer must give to its employees. It is a certificate of the employee's annual income and the taxes withheld from each month's wages for the previous calendar year.

There are also other Fiche forms depending on the type of income:

• Fiche 281.11: Used for income from social benefits such as pensions or unemployment benefits.
• Fiche 281.20: Used for the self‑employed and freelancers.
• Fiche 281.25: Used for author's fee and artistic income.

And other.

The forms differ not only in colour but also in content.

The form for residents (Déclaration à l'impôt des personnes physiques - IPP, or Aangifte in de personenbelasting) is red. The tax office sends it out by the end of May.

The form for non‑residents (Déclaration à l'impôt des non‑résidents, or Aangifte in de belasting niet‑inwoners) is green and is usually sent out during September and October.

You either received a red form or a green form:

The red one is for filing tax returns for Belgian residents.
The green one is for non‑residents of Belgium.

We will be happy to help you fill in your tax return. Just fill in the order form.

The tax office will process the tax return and then pay the overpayment. The whole process takes on average 2 ‑ 13 months from the time the tax return is filed.

After filing your tax return, the tax office will send you a tax notice stating the amount of tax to be paid and the due date. This is usually within two months of receipt of the tax notice (Aanslagbiljet).

Every Belgian resident and non‑resident who earned income in Belgium is required to file a Belgian tax return for the previous calendar year, known as the tax year.
