Who should pay the tax?

The tax is payable by:

  • The holder of an environmental permit in the Brussels-Capital Region on 1 January of the tax year. If this holder is unknown or insolvent, the owner of the establishment, for which the permit was obtained, is liable for the payment of this tax.
  • If there is no class 1 or 2 permit for an establishment that should have one, it is the operator of the establishment who is liable for the tax. If this operator is unknown or insolvent, the owner of the establishment, for which the permit should have been obtained, is liable to pay this tax.

How is the tax calculated?

The amount of the tax depends on the surface area of the holding, the number of items included in the environmental permit and the number of establishments:

Surface area
1 Section
≤ 5 ares
234,80 EUR
more than 5 up to 10 ares
469,60 EUR
more than 10 up to 100 ares
939,10 EUR
> 100 ares
2347,60 EUR
If the number of sections included in the environmental permit is greater than one, the amount of the tax will be doubled.

If there are several class 1 or 2 establishments, the amount of the tax is multiplied by the number of establishments.

The tax is annual and indivisible. The situation on 1 January of the tax year is taken into account.

What are the exemptions?

  • The tax is not due if the establishment or holding has not been in operation for the entire tax year;
  • The tax is reduced by half in the case of agricultural and horticultural businesses.

If you meet the conditions for exemption set out in the ordinance, you can benefit from an exemption by sending a written request to Brussels Fiscality within six months of the seventh day following the sending of the tax bill.
