Requesting a provisional income adjustment form for self-employed persons

The provisional income adjustment form sets out the professional income from the self-employed person's various activities which form the base from which the social security contributions are calculated by the Social Security Centre (Centre commun de la sécurité sociale - CCSS).

Adjustments can be made for a maximum of 5 fiscal years prior to the current year (e.g. 2020 - 2025).

The self-employed person enters an estimate of their income in the 'anticipated annual income' column, for each category of income indicated, and for each individual fiscal year. They return the signed form to the CCSS to adjust the contributions for professional income. The outcome of the adjustments is shown on the account statement the month after the CCSS receives the form.

Once the Luxembourg Inland Revenue (Administration des contributions directes - ACD) has disclosed the final income to the CCSS, it may only be amended by submitting a correction certificate issued by the ACD.

Time frame for delivery: 3-4 working days

Delivery address: The form is sent to the insured's address as listed on the National Registry of Natural Persons (Registre national des personnes physiques - RNPP).
