Some of the cash will go to expanding operations at the reception centres in Joutseno in south-eastern Finland and Oulu in the north. However most of it will be used to cope with the expanding number of asylum seekers.
More funds are also needed because last spring officials did not foresee the cost of refugee family reunifications.
The nation's two dozen refugee reception centres are currently functioning at over 90 percent capacity, and more applicants are on their way.
Last year the number of asylum seekers shot up to more than 4,000, from about 1,500 the previous year. However the numbers remain much lower than in neighbouring Sweden and Norway.
