Which tax returns do I need to file, and how often?

A typical capital company files monthly VAT and a withholding-and-premium service return, quarterly advance tax, and an annual corporate tax return. Those obligations rest respectively on the VAT Law (No. 3065), the Income Tax Law (No. 193), the Social Insurance and General Health Insurance Law (No. 5510) and the Corporate Tax Law (No. 5520). Depending on what you do, stamp tax, special consumption tax (ÖTV) or accommodation tax returns can arise on top of those.

The filing dates and the payment dates are not the same, which is where companies come unstuck: missing either produces a tax-loss penalty and late-payment interest. We put every obligation on a single tax calendar and run the follow-up that keeps those penalties from arising at all.
