They may be required to hire a certified accountant to file the tax report but audited? I asked my local accountant and in our country small companies below EUR 500,000 annual turnover don't need to file audited tax reports.
Looking at archive.org, it looks like this page has been modified this year. I hope someone will confirm.
I make a big thing about it because it is an additional expense but more than an additional expense it is an uncertain expense depending on the number of transactions in your book keeping. There is the same problem in Hong Kong and one men businesses have found it quite pricey.
I know already how much it will cost in Cyprus. It will cost at least 1000 euros and then it depends on the number of transactions.
In Latvia, there is no audit too when annual turnover is less than 800,000 euros.
