In order to encourage more people to sign up for a trade union, the government will propose a law to increase the tax deduction for the trade union membership fee. Today, it is 6000 DKK. They want to increase it to 7000 DKK.
Also, to be able to get a tax deduction on the private wage insurance (lønforsikring), you will need to pay at least 1300 DKK for an a-kasse membership per year.
