Yes, if used within the context of my Belgian professional activities and not older than 5 years prior to the start date. Some examples are: car, ICT, office furniture or other specialised equipment. Any interest incurred on related business loans are tax deductible.
In reference to the car, many times a 5/7 working day ratio can be applied to compute its deduction. Note: car expense for freelancers is 75% of the 5/7th. For companies it is a different matter. Leuven Accountants would be happy to discuss with you personally.
