Contracts state a maximum amount for their whole term, often several years. That amount differs from what was paid. Purchases, services and works paid to companies by the region in 2025: €1.18B (its accounts).

674 contracts signed in 2025 · €388.1M before tax
Why this total differs from the €1.18B of purchases, services and works paid to companies
These are the amounts of the contracts signed in the year, over their whole length, not what was paid. The money paid in a year also goes to older contracts and to purchases too small to be published (under €40,000 excl. VAT). For a framework agreement, the amount is a ceiling.
Investment and works
€795.8M of capital spending in 2025 (building, renovation, equipment), €64 per resident. Mainland regions: €47.

Who is part of Île-de-France
Understanding these figures
Who does what
The region pays for high schools, regional trains (TER) and intercity coaches, school transport outside towns, aid to businesses, vocational training and apprenticeships.
Why the levels are not added up
The same euro can appear twice: once when a region or a département pays a grant, again when the town spends it. Each page shows its own body’s spending.
Where these figures come from
Spending: the accounts of the main budget published by the DGFiP, by public policy. Revenue, debt and taxes: OFGL. Contracts: published contract data (DECP), amounts planned at signing.
