Businesses generally use the 1 January to 31 December calendar year as their accounting year, which is the same as the fiscal year for tax purposes. However, a company may, with permission, adopt a non-calendar year-end.
Accounting Standards
Domestic companies are required to use IFRS Standards as endorsed by the Financial Supervisory Commission (FSC), which exclude a few of the original options permitted by the IASB. Companies can also obtain the approval of the FSC to use IFRS Standards as issued by the IASB. Foreign companies have the option to choose between IFRS Standards as endorsed by the FSC, original IFRS Standards, or US GAAP.
