The new rules involve gradual cuts in benefit where job seekers fail to comply with requirements to apply for work. They will also have to submit reports accounting for their efforts.
Under the scheme, people will now be able to file their monthly reports online.
"This is a very big change," Katarina Mattsson of the Swedish Federation of Unemployment Insurance Funds (A-kassornas samorganisation), told Swedish Radio News.
According to Mattsson 150 new case workers have been recruited in order to deal with the increased work load which the scheme is expected to generate.
It was approved by the Swedish parliament in the spring of 2013 and is expected to increase the Public Employment Service's case load by some 160,000 per year.
