Corporate income tax

Annual CIT return is calculated at 150 days after accounting year-end. Half-year CIT is calculated two months after the end of the first six months of the accounting period.

VAT and withholding tax

VAT is shown monthly for VAT-registered companies. Withholding tax appears monthly as a reminder where payments subject to withholding are made.

Annual accounts and DBD

The calendar uses AGM within four months after year-end, shareholder list within 14 days after AGM, and financial statement filing within one month after AGM.
