TAX DATE. The tax return, whether completed online or on paper, meets a very specific schedule, and certain deadlines not to be exceeded. We take stock.

[Updated on April 11, 2023 at 9:27 a.m.] The online declaration campaign begins on Thursday, April 13, 2023. As every year, the tax administration draws up a precise calendar of tax declaration deadlines. Deadlines set according to your department of residence, and the method of declaration chosen (online, paper). This year, be aware that the declaration must be made online, except for taxpayers who do not have Internet access or who do not have the capacity to use digital tools. Here are the four main dates to know for this 2023 reporting period:

If you are late in filing your tax return, an increase in your tax will be applied. 10% in the absence of formal notice, 20% if you submit your declaration within 30 days following the formal notice, and 40% if the declaration has not been filed within these 30 days. Please note, if the tax authorities discover that you are carrying out an illicit or undeclared activity, an 80% increase will be automatically applied, without formal notice. Finally, late payment interest is also applied, amounting to 0.20% of the tax due per month of delay (2.4% over one year). Interest that applies until the last day of the month in which the tax return is filed.

Like every year, the arrival of spring rhymes with tax declaration. And despite the introduction of the withholding tax four years ago, you will not escape it. Indeed, you will have to complete your tax return again, or check the information pre-filled by the tax authorities in your automatic declaration. The sending of pre-filled declarations will extend from April 6 to 25, 2023. The opening of the online declaration service will open its doors on April 13, 2023. The deadline for taxes online at impots.gouv.fr depends exclusively on your department number. We advise you to pay close attention to the deadlines after which it will no longer be possible to declare your income. An oversight that could cost you dearly with a financial penalty. In total, three zones have been determined by the tax authorities. Here are the deadlines for 2023:

To declare online, you must connect to your private space with your tax number and your password. If you do not yet have a password, enter your tax number, your online access number and your reference tax income. You will find these identifiers on the tax return received in April (tax number and online access number) and on the tax notice received in August N-1 (reference tax income). If you have forgotten your tax number or your password, on the authentication screen, the procedures allow you to recover your identifiers.

Once authenticated, select the “Declare my income” service. Your online declaration will be pre-filled with information known to the administration. All you have to do is verify your marital status, your address and the pre-filled amounts. You can correct them if necessary. Then, you will complete the other income you have received and the charges, reductions or tax credits to which you are entitled. Don’t forget to sign your online declaration for it to be taken into account.

This year, the tax return must be done online. However, there are certain exceptions and some taxpayers can still complete the paper form, if they do not have Internet access or if they do not have the capacity to use digital tools can still use the paper form. In this case, the paper tax return can be made until May 22, 2023 midnight, the postmark being authentic, regardless of their place of residence. The deadline is therefore the same for everyone.
