If you have already re-registered your company, make sure you don't forget to publish your accounts for the past years in the Commercial register. The accounts report is usually done by your company's accountant. However it is preferable not to rely only on your accountant for publishing the report in the Commercial register. Usually accountants are not familiar with the Trade Act in details and you might receive a rejection for publishing the report from the Registry Agency.
Along with the company accounts report, you have to present certain formal company documents as well as a properly filled application. Make sure you take advantage of the services of a good lawyer. Otherwise you might miss the deadline for publishing the annual accounts report, because of a rejection of the application.
