Every entry below is the rule as Egypt 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.
Two provisions of the Income Tax Law point in different directions, and the honest reading is to publish the formula rather than a date. Article 5 names the calendar year: «A tax period is the fiscal year beginning the first of January and ending on 31st of December each year», and the same article adds that «Tax may be calculated for a period shorter or longer than twelve months.» Article 83, which sets the deadline, prints two branches in one sentence for legal persons — before the first of May every year, or «within four months following the end of the financial year for legal persons». A statute that offers the fourth month after a financial year as an alternative to a calendar date is a statute that expects some companies to close their year elsewhere than 31 December. What is deliberately not asserted here is how a legal person sets a financial year other than the calendar year, whether that requires notice or approval, and how a period shorter or longer than twelve months is treated: the Executive Regulation governs those accounting procedures and was not read for this entry. The consequence for this page is concrete. The annual corporate income tax return is counted from the end of that year and cannot be printed as a calendar date until the company states which year it keeps. The Tax Authority's own announcement of 29 April 2026 names Thursday 30 April 2026 as the last day for companies' returns for 2025, and that date is the formula applied to a company whose year ended on 31 December — not a fixed statutory date for everyone. The other four duties below do not depend on the financial year in the same way: two run from the end of a calendar quarter, one from the end of the monthly value added tax period, and one from the day turnover crosses the registration threshold.
