Each year there are deadlines that must be met for delivering your IRS return. To avoid irregularities in your tax situation, it is important not to fail to share this data. See, in our article, all the important dates for the year 2023.

It should be noted that failure to meet the IRS deadlines for 2023 could lead to more serious consequences, such as loss of certain rights or even fines. In this sense, it is very important to write down each of the schedules which you will have to comply with the taxes.

What are the 2023 IRS deadlines?

Surrendering the IRS is a few-step process that will unfold over the coming months. You should pay attention to the calendar imposed by Finance so that you do not miss any of these important dates.

To help with this process, we go month by month to better understand what tax responsibilities you will have throughout the year. Mark these milestones in your diary now:


By this date, you must notify your household’s status, in case it changes.

In cases of marriage or divorce, birth of children or if they are no longer dependent, change of address or in case of death, these situations should be notified to the Tax and Customs Authority.

If there are no changes to report, then you can simply verify that your Finance Portal details are correct. If you don’t make any changes, the data that counts for IRS purposes is that used on the last return made.

This is one of the most important IRS deadlines for 2023. You have until this date to review all expense invoices on the e-invoicing platform, which you can access through the Finance Portal.

This process is crucial as it verifies that there are no missing amounts to show up later on the IRS return.

Through the electronic invoice you can analyze every expense you have made and verify that everything has been entered in the correct field or that there are no missing items that should be declared.

Take into account:

If you have invoices that have not yet been assigned to a category, they will be located in the “Additional Invoice Information” section of the e-invoicing platform.


If you are in doubt about reported expenses, this is one of the IRS deadlines to watch out for in 2023. Once the invoices are settled, by this date you will be able to consult the amounts of withholdings for collection related to previously reported expenses .

It is possible to check these amounts through the Finance Portal, as well as other expenses from entities that are exempt from issuing invoices, such as tuition fees for public educational institutions or housing rents.

If you do not agree with the values ​​of the collection deductions, you will have this period to dispute these data and file a claim with the Tax and Customs Authority.

In this way, you can check whether the household overheads and VAT deductions due to the invoice requirement are consistent with your calculations. Analyze each owner’s case, including dependents, to get an idea of ​​the expenses being accounted for.

Deductions from health and education levies like real estate and housing charges cannot be disputed at this stage. However, these values ​​can be corrected, if necessary, when filing the IRS return.

If this is the case, check that you have the correct documents with you to prove your claims.

Until this date, you must ensure that the IBAN displayed in the Finance Portal is the correct one in order to receive your IRS refund, if it is processed. If you are registered non-ordinarily resident (RNH), you have until today been able to elect to be taxed under this status for the 2022 IRS due next year.

Thus, it becomes one of the IRS’s fundamental deadlines for preparing to deliver the return itself. You will also have until the 31st to select the entity to which you want to pay either the IRS or VAT (or both), if any.

April, May and June

  • From April 1 to June 30

This is the time to file your 2022 income tax return with the IRS. You have until June 30th.

To make this delivery, you can complete the form 3 return and deliver it to the Finance portal or alternatively via the IRS automated function.

This is one of the most important 2023 IRS deadlines to note, as after this delivery you may be eligible for a refund from the IRS. If you claim in the first few weeks of this period, this refund is usually settled towards the end of June.


If everything is turned in by the due legal deadlines, by that date, Finance is responsible for sending the IRS settlement. You can consult this document to check how the tax was calculated by the Tax and Customs Authority.

Head up:

If you haven’t received your IRS refund yet, it should be delivered by the end of this month.


This is the last IRS deadline for 2023 that you should consider. By the 31st of this month you will have to pay additional tax to the State, if necessary.

After this potential charge, you will be free of liability for the remainder of the year regarding the IRS. If you missed the 2022 IRS filing deadline and owe tax, you have until Dec. 31 to do so.

What if you miss the 2023 IRS deadlines?

If you do not meet the deadlines specified above for each of the months, then you may be subject to certain tax consequences.

Failure to declare DOU leads to the imposition of a fine. Its severity depends on the delay and how the condition is corrected.

According to article 116 of the General Statute of Tax Offenses, failure to submit tax returns is punishable by a fine of between 150 and 3,750 euros. If you undergo a procedure of this kind, we advise you to be properly informed with Finance.

Therefore, it is important to keep in mind each of the dates mentioned in this article. Don’t carelessly forget an important delivery or statement and lose money, both for collection deductions and possible fines.
