The system currently has 51,000 users. However, the National Tax Office (Apeh) is publishing new, corrected versions of the filing software every week. Because of that, companies often have to do their tax returns again. Apeh promised to publish the terms by which the tax returns are revised on its homepage back in September, but they are still not available online, chairman of the National Association of Tax Advisors and Bookkeeping Service Providers, László Zara complained.
