Tuesday marks eight years of South Sudan's independence from Sudan but there will be no big celebrations because of the tough economic situation in the country, independent Eye Radio reports quoting Information Minister Michael Makuei.
There have only been big celebrations once since the civil war began in 2013.
"There will be no celebration at the national level, but there will be a low-profile celebration at the presidency, because we don't want to lose money for doing celebrations as we used to do," Mr Makuei told Eye Radio.
President Salva Kiir is expected to make a national address.
South Sudan seceded from Sudan in 2011 after a decades-long civil war. But fighting that began in 2013 has thrown the country into turmoil and severely dented economic development.
A peace deal has been agreed but has not yet been implemented.
