Contribution is the action and the effect to contribute (pay taxes, voluntarily give one amount for a particular purpose, participate, help others). The term derives from the word latin contributĭo.
A contribution may therefore be a tribute that the taxpayer must pay the fact of having obtained a benefit or because of the increase in the value of its assets after the completion of work. Examples: 'Sir, we noticed you have contributions in arrears", «last month, I had to pay a contribution of 200 euros for the construction of the cellar», «the candidate promised to reduce the contributions.»
As the State is benefiting some citizens regarding public works (and not the whole of the population), the administration establishes contributions for the direct beneficiaries, which must contribute (finance) wholly or in part in the work.
There are different types of contribution. The direct contribution (weighing on people or property), the indirect contribution (levied on specific acts of production, consumption or trade), the so-called territorial taxes (on property of rural or urban nature) and the contribution of war (imposed by the armies to the populations they occupy) are some of them.
Overall, a contribution is an offer that can be given as well to a person than to a campaign or to an organization, etc.: "the Bishop asked people an effort in the contribution of solidarity for the poor", "my contribution to this company was large enough: I do not deserve to be treated this way. ''
