Holidays that will shift filing deadlines in 2027

Ramadan Feast 9–11 March, Feast of Sacrifice 16–19 May 2027. Which deadlines move?

In 2027, deadlines falling on a public holiday or weekend move to the first working day after it under Article 18 of the Tax Procedure Law. Half-day eves do not extend a deadline by themselves; if the Revenue Administration announces otherwise, it is added to our calendar.
