JAKARTA In a number of countries in the world, water absorption is quite rare. The reason is, with a limited area and massive development, making water infiltration an important item for maintaining the ecosystem.

On that basis, the state then encourages its citizens to provide a piece of land as a place for rainwater to enter. For those who cannot fulfill this, the government imposes a rain tax as a form of contribution to the environment.

Launching on the Tax website, it is known that the rain tax is an annual contribution on a waterproof surface that can cause drainage problems and water pollution located in individual or business property.

The government also collects rain taxes so that they can be used in most of the same sectors, such as flood control facilities, cleaning, and updating waterways. In Indonesia, the rain tax has not yet been implemented by the government.

"There is no (rain tax in Indonesia)," said an internal VOI source at the Ministry of Finance when confirmed on Tuesday, December 27.

Generally, the countries that set this fiscal policy came from the European continent. Here is the review.

1. Germany

The Bavarian country first introduced a rain tax in 1990. At that time, the applicable tariff was still quite low, so far it has reached 2.6 US dollars per square meter. Uniquely, this rule actually made German people flock to build rainwater storage systems such as parks, gardens, yards, and so on.

This effort indirectly helped the government to mitigate flood disasters because the water discharge that enters the land is increasing. As a result, as many as 1.8 million families built rainwater reservoirs and managed to save 110 million liters of water in a study conducted in 2009.

2. Poland

In neighboring Germany, Poland, also implemented the same policy. Local authorities say the rain tax applies to Polish people who have a property of at least 600 square meters and a construction rate of at least 50 percent.

From the information gathered, it was revealed that the tariff provisions were applicable in several countries. First, property owners with a reference rate of up to 10 percent are subject to a rain tax rate of 0.90 per square meter worth of PLN (Polish currency).

Second, for more efficient installations with a retention rate of 11 percent to 30 percent, a PLN rate of 0.45 square meters is charged.
