The experts at Ayming Belgium have developed an advanced expertise under Finance Performance. The optimisation of taxes in connection with professional properties concern office buildings, commercial centres, hotels, clinics and homes, and industrial buildings.

Belgian properties prey to many taxes:

Turning to the cadastral income, serving as base for the withholding tax and the Brussels regional tax, many taxes can soon accumulate to form a heap of taxes payable to the local and regional authorities of the country.

Ayming provides you with a simulation tool to anticipate the amount of this tax!

You will then be able to :

  • Anticipate the amounts and therefore control your budget.
  • Check the assumptions related to your investments.

A reduced time window for optimisation:

Optimising the taxation of your immovable assets investment is possible only for:

  • demolition,
  • construction,
  • reconversion,
  • extensive renovation of your property,

and this in a very limited space of time. For example, you have 60 days to oppose the notification of a new cadastral income once the CI is fixed in time.

Acting in depth, on the bases of calculations and respecting the deadlines is therefore crucial for obtaining effects in the short term and over the long term.

A unique set of levers to optimize your properties taxation:

With the optimisation of the taxation of more than 100 office buildings in Belgium our experts have acquired a unique know-how allowing them, under certain conditions detailed above, to:

  • Reset the cadastral income to its correct level, making use of:
    • a single database allowing identification of comparison points of deemed rental value built up over more than 15 years;
    • the expertise of expert surveyors tasked to recalculate, correctly, the different types of taxed surfaces;
  • Optimise the calculation basis of the withholding tax on immovable assets of the property and apply possible exemptions for works, unproductiveness, …;
  • Reduce the regional taxes (tax on non-residential surfaces in the Brussels Region, known as the tax on offices), municipal taxes (on car parks, for example) and other associated town planning charges.
