On April 3, the 2023-2024 income campaign begins. Like most years, it comes with new details. One change concerns the reference number, a key identifier taxpayers use to access the Tax Agency’s online services. This number helps people consult their tax information and access services for the income campaign, including scheduling appointments or obtaining a draft of their return.
The new reference number consists of six characters and serves as a digital credential comparable to an electronic certificate, DNIE, or Cl@ve PIN. Because last year’s reference no longer works, it must be requested again for the current campaign.
How to obtain the new reference number
Starting with this campaign, obtaining the number is straightforward. The taxpayer can retrieve it by entering a specific amount on the Tax Agency app or website. The value is the figure found in box 505 of the previous year’s income tax return.
First, the taxpayer provides the tax identification number (NIF), the expiry date of the DNI, or the NIE support number. Then the amount for box 505, which corresponds to the “General taxable base subject to levy,” is entered.
If the user did not file a return in 2022, the value to enter in place of box 505 can be the last five digits of the IBAN of a bank account held in 2023. This alternative data point is also requested if the 2022 box 505 result was zero.
The reference number obtained through this process allows the taxpayer to perform income campaign related operations at a later time. It is advisable to keep it handy. If it is lost, the identical process described above can be repeated to generate a new number, up to ten references per day.
