That’s it, it’s over. Well almost. Taxpayers from departments ranging from 55 (Meuse) to 976 (Mayotte) must hurry to complete and validate their income declaration. Because if they have benefited from additional time, the fateful time for them is set for this Thursday, June 4 at 11:59 p.m.
Like every year, Bercy organized the declaration campaign in several stages. One way to avoid seeing taxpayers all flocking to the tax site at the same time, at the risk of clogging up the servers. The first deadline was therefore set for May 19 for households still using the paper form, a method normally reserved for those who are unable to use computers, and the website opened since the launch of the 2026 declaration campaign on April 9.
For the online declaration on the official website impots.gouv.fr, taxpayers from departments numbered 01 (Ain) to 19 (Corrèze) were the first to have to hurry, with a deadline set for them at May 21. A week later came the turn of the departments of Corsica (2A and 2B) up to that of Meurthe-et-Moselle (54). This time, it is for the remaining departments, from Meuse to Mayotte, that the countdown has started before the deadline this Thursday evening.
The end of the reporting period does not, however, mean the end of income tax operations. Indeed, the validation of the declaration allows the tax administration to draw up the accounts for the year 2025, comparing the tax to be paid and the sums already paid last year, month after month, by withholding tax.
A refund of the overpayment “on July 24 or 31”
There are then three situations, reminds Bercy. First, some households will be pleasantly surprised to see that they are entitled to a refund. This is the case for those who have had too much withheld at source compared to the amount of tax they ultimately have to pay or who have incurred numerous expenses entitling them to a tax boost (donations, home employment, etc.). In this case, beneficiaries will receive a transfer directly to their account, “in most cases, on July 24 or July 31, 2026” specifies the tax administration. Those who have not provided their bank account number will receive a check.
Conversely, other households will have to supplement what they have paid over the months with withholding taxes. A situation which can be explained by higher income in 2025 compared to 2024 or by less expenditure qualifying for a tax reduction. In this case, the amount due must be paid at the start of the school year. In one go, at the end of September, if the amount does not exceed €300. In four monthly withdrawals, between September and December, if the amount is greater.
Finally, many households will have nothing to pay and nothing to recover. This is particularly the case for many non-taxable households – around 19 million out of the 41 million tax-paying households last year.
