is payable by any person who has a residential unit at one's disposal, for any reason (owner, renter, occupant for free), on 1 January of the taxable year. The tax base is a notional rental value of the residential property. In 2005, the revenue from the housing taxes amounted to €13.37 bn. Land tax The property tax on built lands (taxe foncière) is applied to properties built in France. The taxable properties consist of all permanent constructions, i.e. buildings (blocks of flats, houses, workshops, warehouses, etc.). The tax base is equal to 50% of the notional rental value of the building (i.e. the value set by the tax administration) and on land/location value. There are many exemptions and exceptions. In 2005, the product amounted to €17.73 bn. Taxes by source In 2007, revenues amounted to €818.9 bn, or 43.3% of GDP. There are four beneficiaries of the tax revenues: in 2007, social security administrations have received just over half; the state and the central government bodies near a third; the local administrations (APUL) nearly 13%; the European Union (EU) less than 1%. Direct and indirect taxes account for 62.8% of total revenues in 2007. State resources come almost entirely from taxes. The social security bodies are financed largely by social contributions but also by taxes, including the general social contribution (CSG) and the contribution for the repayment of the social debt (CRDS), which represented in 2007 a quarter of the funding of the Social Security administrations. Local administrations are mostly financed by the four main local direct taxes (housing tax, property taxes and business tax). Public finances The public deficit amounted to 2.9% of the GDP (€50.6 billion) in 2007 compared to 0.2% on average in the euro zone, excluding France. The actual deficit may exceed the threshold of 3% if the situation deteriorates. The public debt amounted in 2007 to 63.9% of GDP, which represents $47,000 per person employed. Public debt has increased in the last years, and the expenditures to repay the interests have reached 52 billion € in 2007 or 2000 € per person in employment. The deficit of social security administrations remains at €11 bn, but the corresponding debt ("social debt") has increased. The deficit of local administrations is still limited, but amounted to €7 bn in 2007, as a result of a spending growth significantly higher than that of the revenue in the recent years.
