Everything you need to know about tax returns in Luxembourg
Filing deadlines, companies concerned, required documents and formalities: find the answers to your questions about corporate taxation in Luxembourg, as well as the steps to follow.
What tax returns are companies required to file in Luxembourg ?
Tax obligations vary depending on the legal form, business activity and specific situation of each company.
For companies subject to corporate income tax, an annual tax return must be filed for the assessment of :
- corporate income tax (IRC),
- municipal business tax (MBT), where applicable,
- net wealth tax.
Form 500 is therefore the standard tax return for the companies concerned. Other tax returns may also be required, particularly for withholding tax or VAT.
What is the deadline for filing tax returns in Luxembourg ?
Filing deadlines vary depending on the tax return concerned in Luxembourg :
- For companies, Form 500 must be filed by 31 December of the year following the tax year.
- VAT returns may be filed monthly, quarterly or annually, with specific deadlines depending on the company’s turnover. Wage withholding tax returns are also filed periodically, depending on the amount withheld.
- Other tax returns, such as Forms 205, 300, 506A, 700, 800, etc., also have their own filing deadlines.
Where and with which authority should tax returns be filed ?
Companies’ tax returns are submitted to the Direct Tax Administration (ACD) through the competent tax office in Luxembourg.
For corporate tax returns, filing is carried out online:
- via the MyGuichet.lu platform, in your professional account.
For eligible cases, the ACD also allows the use of a structured XML file to pre-fill the filing assistant on MyGuichet. Camele’on allows you to generate this XML file in just a few clicks, ensuring a standardised document that complies with legal requirements.
Is Form 500 mandatory for all companies in Luxembourg ?
No. Form 500 does not apply to all companies in Luxembourg. It applies to companies subject to the relevant tax obligations, particularly those relating to corporate income tax, municipal business tax and, where applicable, net wealth tax.
The filing requirements and tax returns to be submitted therefore depend on :
- the legal form
- the company’s tax situation
Camele’on dynamically generates tax returns for both companies and individuals, in the format required by the authorities.
How do you file corporate income tax in Luxembourg ?
For a company subject to corporate income tax, Form 500 must be filed with the Direct Tax Administration (ACD).
The steps to follow are :
- Find the required information in the form, based on the company’s accounting and tax data.
- Complete Form 500, either directly on the MyGuichet.lu filing platform or using suitable software that generates the tax return in XML format.
- File the tax return with the Direct Tax Administration (ACD) electronically via the MyGuichet.lu platform.
Automating tax returns can provide significant time savings for fiduciaries. This is what Camele’on offers, reducing manual data entry and simplifying the preparation of tax forms.
