Every entry below is the rule as Armenia publishes it. It is a reference, not a calendar: where a deadline runs from something only you know, this page says so instead of showing a date.
This is the rule as published by the registry, checked against the primary source on the date shown. It is not your filing date. Where a deadline runs from incorporation, from a fiscal year the company itself elects, or from an event only you know about, no date can be derived here at all — the figure you see is the formula, not the answer. Extensions, transitional regimes and entity-specific exemptions are not reflected. Confirm with the registry before you rely on a date.
Armenia fixes the reporting year by statute. Article 22 of the Law of the Republic of Armenia on Accounting (HO-515-N of 26 December 2002) provides: «Հաշվետու տարին տվյալ տարվա հունվարի 1-ից մինչև դեկտեմբերի 31-ը ներառյալ ընկած ժամանակաշրջանն է» — the reporting year is the period from 1 January to 31 December of the given year, inclusive; for a newly established organisation the first reporting year runs from registration to 31 December of that year. Nothing in this record is computed from the period end: every deadline below is either a flat calendar date or a count of days from the end of a tax period, so the reporting year is recorded for context rather than used as an anchor. One caveat belongs here: the TAX year under the Tax Code of Armenia was not read for this record, because the text of the Code could not be read past its opening articles. The statement above is the accounting reporting year and not a statement about the period used for profit tax or VAT.
