Data of companies and individuals owing more than 5,000 euros for more than three months will be published on a monthly basis, under the reform tax procedure act passed in November 2012.

DURS revealed earlier this month that the list will contain 4,476 legal entities, owing a total of EUR 578.07m, and 11,441 individuals, whose debt amounted to a total of EUR 350.95m as on 25 March.

Also disclosed will be the names of businesses that have fallen more than three months behind with social contributions for their employees.

The purpose of the measure, introduced by the previous, Janez Janša government, is to stimulate persons liable to tax to settle their obligations on time and to help reduce the scope of the informal economy.

Speaking to the press on Friday, PM Alenka Bratušek said the EUR 5,000 threshold seemed a bit too low, but "we have not yet discussed potential changes".

But the Chamber of Commerce and Industry (GZS) is against what it believes to be a radical measure that will cause more damage than good.

The GZS fears that the list will include cases in which appeal is still pending or companies that cannot pay tax debt because they have not been paid honestly for the work done.

However, DURS says that those who are unable to pay taxes for grounded reasons beyond their control, and have been granted a deferral or abatement are not treated as tax debtors and will appear on the list.

But the GZS argues that the given solution is radical compared to solutions in companies such as Austria and Germany, and that it puts Slovenia on a par with Bulgaria and Croatia.

In the case of businesses, DURS will publish the name, owner (names, surnames and date of birth of those owing over 25%), seat and the tax number of the company falling behind with the payment of taxes.

Individuals will be identified with names, surnames and date of birth, and in special cases municipality or country of residence.

The biggest single tax evader owes the state as much as EUR 24m, DURS explained to the STA, but added the list would not provide the exact sum of unpaid taxes.

Rather, the companies and individuals will be ranked in several groups, with one group consisting of those with a debt of 5,000 to 10,000 euros.
