Germany has struggled to accommodate a wave of asylum-seekers from war zones such as Syria but also from countries without military conflict in southeastern Europe, including Albania, Serbia and Kosovo.
Europe's biggest economy has become the top destination for those fleeing war and persecution but de Maiziere said other European partners must also share the refugee load.
"The European Commission should act against member states that are not assuming their responsibilities," de Maiziere said as he announced the new official estimate."This development is a challenge for us all," said the minister.
Berlin had previously expected 500,000 asylum-seekers to arrive this year.
Vice Chancellor Sigmar Gabriel, who described the jump in refugee figures as the 'biggest political challenge of the coming year', had stronger words for the EU which he said has 'failed miserably in this task'.
De Maiziere said he sought action from the EU over the visa-free Schengen travel zone, as calls mounted from some German regional officials for controls to be reinstated.
