Each year there are deadlines for submitting the IRS return. To avoid irregularities in your tax situation, it is essential that you do not omit this information. Check out all the important dates for the year 2023 in our article.

It should be noted that failure to comply with the IRS deadlines for 2023 could lead to more serious consequences, such as the loss of some rights or even fines. In that sense, it is very important that you do each of the times which you must comply with the Tax and Customs Administration.

What are the IRS deadlines for 2023?

The delivery of IRS is a process that involves a few steps that will stretch over the coming months. You will have to pay attention to the calendar imposed by Finance so as not to let any of these important dates escape you.

To make this process easier, we’ll go month by month so you can better understand what tax responsibilities you’ll have throughout the year. Mark these milestones in your calendar now:


Until that date, you must provide the composition of your household, in case it has changed.

In the event of marriage or divorce, the birth of children or no longer dependents, change of address or death, these situations must be reported to the Tax and Customs Administration.

If there are no changes to indicate, you can easily check whether your data on the Finance Portal is correct. If you make no changes, the data accounted for for IRS purposes will be the data used in the last statement 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 because it verifies that there are no missing amounts to be presented later in the IRS return.

With the help of the e-invoice you can analyze each expense incurred and check whether they have all been entered in the correct sector or whether there are any missing data that need to be declared.

Take note:

If you have invoices that have not yet been assigned to a category, they will be listed in the “Additional invoice information” section on the e-invoice platform.


If you are in doubt about the declared expenses, this is one of the IRS deadlines you should pay attention to for 2023. After settlement of the invoices, you can until that date collect the amounts of the deductions from previously declared costs.

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

If you do not agree with the amount of the deductions collected, you have this period to dispute this information and submit a claim to the Tax Authorities.

This way you can check whether the general family costs and the VAT deductions, due to the invoice obligation, are in accordance with your calculations. Analyze each holder’s case, including dependents, to get an idea of ​​the expenses being accounted for.

Deductions from healthcare and education collections, such as real estate and housing costs, cannot be disputed at this stage. However, these values ​​can be corrected, if necessary, when filing the IRS return.

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

Until this date, you must ensure that the IBAN that appears on the Finance Portal is the correct one to receive the IRS refund, if it is processed. If you are registered as a Non-Ordinary Resident (RNH), you have until now to opt for taxation under this regime before the IRS 2022 which is issued the following year.

Thus, it becomes one of the fundamental IRS deadlines in preparing the delivery of the statement itself. You also have until the 31st to choose the entity to which you want to pay the IRS or the sales tax (or even both), if applicable.

April, May and June

  • From April 1 to June 30

This is the period for submitting the IRS return on your income for 2022. You have until June 30 to do so.

To make this delivery, you can complete and submit the declaration model 3 on the Finance Portal or via the automatic IRS functionality.

This is one of the most important 2023 IRS deadlines to note, as you may be entitled to a refund from the IRS after this delivery. If you declare in the first weeks of this period, this refund will usually be settled at the end of June.


If everything is delivered within the legal deadlines, Finance is responsible for sending the IRS statement until this date. You can consult this document to check how the tax has been calculated by the tax authorities.

Pay attention:

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


This is the final 2023 IRS deadline to consider. Until the 31st of this month, if necessary, you must pay additional tax to the State.

After this possible write-off, you are free of responsibility with regard to the tax authorities for the rest of the year. If you didn’t meet the 2022 IRS delivery deadline and need to pay taxes, you have until December 31 to do so.

What if you don’t meet the 2023 IRS deadlines?

If you fail to meet the deadlines listed above for each of the months, you may face some tax consequences.

Failure to report to the IRS will result in the imposition of a fine. The severity depends on the delay and how the situation is resolved.

According to Article 116 of the General Regime of Tax Offenses, failure to file tax returns is punishable by a fine of 150 to 3,750 euros. If you are faced with such a process, we advise you to obtain proper information from Finance.

It is therefore essential that you consider each of the dates listed in this article. Do not forget an important delivery or declaration due to carelessness and you will lose money, both for collection deductions and possible fines.
