Recovery charges for 2025 are estimated at €376 million, broken down as follows: €238 million for IR (income tax), €130 million for TF (property tax), €4.7 million for TH (housing tax), and €3.3 million for IFI (wealth tax).
Location and Collaboration
The LILLE 3 SIP is located in the Lille suburbs, at the LOMME CDFiP, 22 rue Lavoisier. This location houses both the LILLE 3 and LILLE 1 SIPs, which collectively serve the entire city of LILLE and part of the Lille metropolis. It also includes the headquarters of the departmental SDIF and the Lille SPF.
First-level physical reception and telephone support are shared between the LILLE 3 and LILLE 1 SIPs on a weekly rotation. When LILLE 3 handles in-person reception, LILLE 1 manages all telephone inquiries for both services, and vice versa. This collaborative approach ensures continuous service coverage.
The “SIP of tomorrow” organizational structure divides the LILLE 3 SIP into three teams: a “Support” team with 17 positions, a “Regularization” team with 12 positions, and an “Accounting-general secretariat” team with 6 positions. This restructuring aims to optimize workflow and enhance service delivery.
