It administers five villages: Blaja (Tasnádbalázsháza), Cig (Csög), Rațiu (Ráctanya), Sărăuad (Tasnádszarvad), and Valea Morii (Tasnádmalomszeg).

At about 2 km (1.2 mi) from the center lies the Tășnad geothermal Spa, known in Romania and abroad for its thermal waters.

Since 2012, Ulrike Sommer from the UCL Institute of Archaeology in London has conducted excavations of the Körös site together with the Satu Mare Museum.

In August 1940, under the auspices of Nazi Germany, which imposed the Second Vienna Award, Hungary retook the territory of Northern Transylvania (which included Tășnad) from Romania.

Towards the end of World War II, however, the city was taken back from Hungarian and German troops by Romanian and Soviet forces in October 1944.
