Deloitte’s tax compliance team addresses the new challenges surrounding the preparation and filing of electronic corporate tax returns in Luxembourg through a hot-off-the press, step-by-step reference guide covering corporate income tax, municipal business tax and net worth tax returns, published by Larcier.

As from fiscal year 2017, the electronic filing of corporate tax returns is mandatory for most corporate entities in Luxembourg. Given the increasingly complex legislative and regulatory framework that applies to corporate taxation, many taxpayers struggle to understand how the rules apply to their specific corporate entity.

This is the context for Deloitte’s brand new publication, currently available in French and entitled “La déclaration fiscale des sociétés commerciales au Luxembourg”, published by Larcier, the specialized publisher of fiscal and legal publishing brands.

“From time to time, our clients and other professionals in our network express the need for a comprehensive reference guide they could turn to when preparing and filing their corporate tax returns. Such books exist for personal tax returns, but until now, no step-by-step guide has been available for corporate tax returns. This is why we decided to write one. With the introduction of the e-filing, the timing was right,” explains Olivier Buscheman, Tax Partner at Deloitte Luxembourg and one of the authors of the book. 

A helpful companion

The publication is written by the Deloitte tax compliance team under the leadership of Olivier Buscheman, Maude Bologne and Grégory Marchal. Over 400 pages, it provides a detailed explanation of how to approach, understand, prepare and electronically file a corporate tax return in Luxembourg, based on the tax and legal framework applicable as of 31 December 2017.

To make the publication as relevant and helpful as possible, the book reflects the structure of the electronic form established by the Luxembourg Tax Authorities for corporate tax returns. Chapter by chapter, the publication takes the reader through the applicable tax legislation and regulations in Luxembourg and illustrates the best approach to each section and different scenarios, through practical examples and multiple screenshots.

The book also highlights the different submission deadlines, explains when to pay corporate taxes and tax advances in Luxembourg, and outlines the potential financial fines applicable to missing or faulty tax returns.      

“Our ambition is to offer a reference guide that we hope will be useful for anyone interested in gaining a deeper understanding of the rules applicable to the preparation and filing of corporate tax returns in Luxembourg. We have added tips and guidance based on common practice, and we are confident it will be a true time-saver when the submission deadline approaches,” concludes Olivier Buscheman.
