Last week, 22 people were charged in a large-scale assistance operation.
Those involved are suspected of having received tens of millions of kronor in assistance compensation on incorrect grounds.
Last year, the Swedish Social Insurance Agency demanded back more than SEK 460 million in incorrectly paid assistance compensation - which was an increase of 250 percent from the year before.
SVT has previously examined the companies that had their payments stopped by the Swedish Social Insurance Agency and the permit revoked by the Swedish Health and Care Inspectorate, IVO.
The review showed that people behind the companies in several cases have been able to continue to make money from assistance activities despite the authorities' measures.
Suggests tightening the law
One problem that the authorities have highlighted is that people who receive assistance compensation can continue to hire companies that have had their permit revoked by IVO.
The government is now proposing, in a legal advice referral, that the Swedish Social Insurance Agency and municipalities should be able to refuse to pay assistance compensation to an individual if he or she hires an assistance company without a permit.
- We want to be sure that the money only goes to companies that have a permit and are serious.
We are closing a gap in the law, says Minister of Social Affairs Lena Hallengren (S).
The idea is that the new law will enter into force on 1 November this year.
- Our security systems can be both abused and used, we must make sure that money does not leak out, says Lena Hallengren.
