Finance Secretary Dr Ken Ngangan says there will be no exception for extensions; closure will be on Monday, 4:06pm.
Dr Ngangan told this newsroom that for the last few years, the Finance Department had been relaxed, which resulted in lax measures.
However, this year will be different as strict measures are in place to monitor this.
He added that now that all government departments are on Integrated Financial Management System (IFMS), it makes his job much easier as he will just switch the system off and all balances will be reverted to zero.
Dr Ngangan calls on all service providers with government cheques for 2017 to present them at their banks before December 31, 2017.
