How VAT applies to your construction work as a self-employed contractor

As a self-employed contractor in Belgium, correctly applying VAT (Value Added Tax) to your construction or renovation work is essential. The applicable VAT rate, 21% or the reduced 6%, depends on the type of work and the client’s situation. Getting it wrong can lead to costly penalties, so it’s crucial to know exactly when the reduced rate applies and how to document it properly.

This guide explains:

• ✅ Who qualifies for the reduced rate

• 🧱 Which works are eligible

• 📋 Your obligations as a self-employed contractor

• 📜 The legal statement you must include on invoices

🧾 1. Conditions for applying the 6% rate

To legally apply the 6% reduced VAT rate, all the following conditions must be met:

✅ The property:

• Is used exclusively or primarily as a private residence (not for commercial purposes)

• Was first occupied at least 10 years ago (based on the calendar year of first occupation)

✅ The works:

• Involve renovation, repair, transformation, improvement or maintenance (excluding routine cleaning)

• Are carried out and invoiced by you as a professional

• Are invoiced to the end user: the private individual (owner, tenant, usufructuary...) who uses the building as their main or sole residence

📜 The invoice must include this required legal statement:

Mandatory legal text to include in your invoices:

"VAT Rate: In the absence of a written dispute within one month of receiving the invoice, the client is presumed to acknowledge that:

(1) the works are carried out on a residential building whose first occupation occurred at least ten calendar years before the date of the first invoice for these works,

(2) that after completion, the building is used either exclusively or primarily as a private dwelling,

and (3) that the works are supplied and invoiced to a final consumer.

If any of these conditions are not met, the standard VAT rate of 21% will apply, and the client will be responsible for paying any additional VAT, interest, and applicable fines."

💡 Tip: You can add the mandatory mention in the notes section of your invoice, as shown in the screenshot!⬇️⬇️

📅 3. What changed in 2022

Since January 1, 2022, you no longer need to have your client sign a declaration. Instead, you must include the legal statement above in every invoice.

👉 If the client does not dispute the invoice within one month, they are presumed to accept that the conditions are met.

⚠️ 4. Responsibilities and risks

• The 10-year age of the property is based on the calendar year of first occupation.

• If you apply the 6% rate incorrectly:

  • You remain liable for any VAT due, unless the error depends solely on information only the client can confirm (e.g. private use).

  • The tax administration may demand corrections, including interest and fines.

🧰 Double-check with your client

• 📆 Is the property over 10 years old?

• 🏡 Is it used as the main residence?

• 👤 Is the client the end user (not a business or developer)?

• 🧾 Does the invoice contain the mandatory text?

• ✉️ Has the client refrained from disputing it within a month?
