The EC was supposed to distribute the cards to over 95 million citizens between September 2015 and June 2016 under the Identification System for Enhancing Access to Services (IDEA) project.
The production of the smart cards was also scheduled to start last month, but there has been no progress.
The EC in January this year struck a deal with a French organisation to manufacture and distribute the smart cards.
Officials said the project director had written to the Planning Commission asking for the extension of deadline.
After that, the Implementation Monitoring and Evaluation Division (IMED) of the planning ministry asked it why the extension was sought for and whether funding from the donor agency and project expenses would increase if it was to happen.
EC Secretariat Senior Assistant Chief (Planning and Development) Saiful Haque Chowdhury sent their response to the IMED on Thursday.
He said they proposed notifying the donor agency first and then extend the deadline without raising the project cost.
Saleh Uddin told bdnews24.com the project did not make any progress until 2013 due to legal complications.
“But now the project is going ahead without problem. The donor agency has been informed. The start was delayed, but we want to extend the project deadline by one and a half years to finish everything properly,” he added.
Election Commissioner Md Shah Nawaz on Aug 4 said they received 10 machines for smart card personalisation.
One of them would be installed at the project office at Agargaon and the rest would temporarily be put at prime minister’s relief office, he had said.
