Ukrainian authorities have assured citizens that any Russian military equipment they seize won’t need to be declared for tax purposes.

They said such items would be considered a "manifestation of the unity and cohesion" of Ukrainians.

After a week of intense fighting, some of the Russian equipment, including tanks, have been left either abandoned or destroyed within Ukraine's borders. 

Some Ukrainians have managed to capture this costly military equipment.

 Ukraine's National Agency for the Protection against Corruption (NAPC) has now declared that captured Russian tanks and other equipment are not subject to declaration. "Have you captured a Russian tank or armored personnel carrier and are worried about how to declare it? Keep calm and continue to defend the Motherland! There is no need to declare the captured Russian tanks and other equipment, because the cost of this ... does not exceed 100 living wages (UAH 248,100)," NAPC's press service said, reported news agency Interfax.
