Attention latecomers. If you made a mistake in your online tax return, know that this is the last day to modify it. You have until 11:59 p.m. (precisely!) this Wednesday, June 26 to make any changes. After this deadline, it will definitely be too late. And since we don’t joke around with taxes, you risk taking a 10% increase.
What if you declared your income on paper? Don’t panic, there is a solution. You have until December 31, 2026 to submit a complaint, specifies the platform impots.gouv.fr.
