The Day of Revenue Service is observed in Azerbaijan every February 11. This professional holiday was established in 2005 to recognize the significant role that revenue service workers play in the country's well-being. It marks the anniversary of the Ministry of Taxes of the Azerbaijan Republic, which was formed on February 11, 2000, succeeding the Tax Inspection Department created in 1990 after the Soviet Union's dissolution. The revenue service is responsible for ensuring compliance with tax laws and addressing violations of legislation. The day serves to highlight the importance of the revenue service in the state's functioning and societal welfare.
