Treasury Day (Dzień Skarbowości) is observed in Poland every July 31. This official professional holiday was first celebrated in 2008 and became a statutory holiday in 2010, marking its significance within the fiscal administration. The date commemorates the adoption of the act on the temporary organization of the treasury and tax authorities on July 31, 1919, following the establishment of the Second Polish Republic in 1918. The holiday aims to integrate the fiscal administration environment and foster a common identity among professionals in the field, including employees of Poland’s tax authorities and treasury. Treasury Day reflects the historical reforms initiated by the government led by Józef Piłsudski, emphasizing the importance of tax and treasury work in Poland's governance.
