Proactive tax advice and planning

At Ilia Consulting, we proactively manage our clients’ tax and legal affairs, without us needing to be prompted and years before they start receiving any fines or penalties due to poor planning. Our main areas of expertise are taxation, tax optimisation, tax savings and tax planning for companies and individuals.

We do not just cover the legal and tax needs of our clients; it is one of our principles to also provide value. Through proper tax planning, we save our clients hundreds of thousands of euros. We use all legal means to minimise tax burdens through approaches such as the application of tax deductions, company incorporation and the creation of corporate structures. We consider tax optimisation to be one of our fundamental values.

At Ilia Consulting, we enjoy providing tax advice and firmly believe that we truly do add value through our services. Your tax consultant will not just make sure that your company is up to date with its tax payments and its relationship with the Treasury but will also do everything legally possible to ensure that you pay less tax.

Greater tax savings

We reduce tax burdens as much as possible through proper tax planning and by applying all the legally permitted deductions. We proactively make the necessary suggestions to generate the greatest tax savings.


Tax preparation
and filing

Through tax advice, preparation, reviews, optimisation and filing, we minimise tax burdens in accordance with the current legislative framework. We avoid any penalties and errors through meticulous supervision and a policy of internal reviews.

All our services are financially guaranteed; if we generate a financial loss for a client, we pay it immediately.
