The Tax Agency expects to earn 24,628 million euros in the current Income Tax campaign. It is 18.4% more than in the previous one, according to data published by the Treasury at the beginning of the campaign. Compared to that figure, refunds to taxpayers drop by 3.2% and remain at 13,271 million.
The distribution of the campaign confirms a trend that is already weighing on homes. The Treasury expects to receive 25.2 million declarations, of which 62% will be returned. The rest, around 7.7 million taxpayers, will have to pay to regularize their situation with the Tax Agency.

The Treasury loses another battle for the exemption from working abroad: it will have to cancel a claim of 11,665 euros from a worker

The Treasury will send its “fear letters” very soon: more than 100,000 taxpayers will receive them between May and June
Who pays, who returns
The planned refunds total 13,271 million euros and benefit 15.7 million taxpayers. The first month of the campaign has closed with 4.5 million returns already processed for an amount of 3,147 million, according to provisional data from the Tax Agency.
The other side of the campaign is payments. The 7.7 million taxpayers with results to be entered must pay the corresponding amount before June 30, the date on which the deadline to submit the declaration with any result ends.
The period is shortened by five days if the taxpayer directs the payment into his bank account. In that case, the declaration must be submitted before June 25.
How to split the payment
Whoever has the Rent to pay can divide the amount into two installments without interest or the need for collateral. The option is provided by the Tax Agency itself and only requires checking the corresponding box when submitting the declaration.
The first payment, of 60% of the amount, is made when submitting the declaration. The second, of the remaining 40%, is charged on November 5, 2026.
The option has no added cost. The Tax Agency only rules out splitting when the declaration is submitted after the deadline or the taxpayer already has outstanding debts with the Treasury.
Anyone who cannot make the payment in two installments can request an additional deferral, subject to the legal interest on the money. The Tax Agency only requires presenting guarantees when the taxpayer’s total debt exceeds 50,000 euros, according to the threshold set by Order HFP/311/2023. Below that figure, the postponement is processed without guarantees.
Concern grows among households
Six out of ten Spanish families reserve money for emergencies, according to the latest European Consumer Payments Report from Intrum. The amount saved, however, is usually insufficient to face unforeseen events such as a tax return to pay.
The study reflects an improvement in financial perception. 83% of those surveyed claim to pay their bills on time, compared to 78% registered in 2023. Despite this evolution, more than half of the participants consider that the rising cost of living in recent years has permanently affected their financial well-being.
Economic fragility is also reflected in non-payments. 8% of Spaniards acknowledge having left between two and four bills unpaid in the last year, a higher percentage than the previous year. The figure grows especially among retirees and the unemployed.
Key campaign dates
The deadline to submit the declaration with results payable ends on June 30. The presentation with direct debit of the payment must be made before June 25 for the account to bear the charge within the ordinary period.
The online presentation opened on April 8. The telephone modality (Le Llamamos plan) is available from May 6 and the in-person appointment at the Tax Agency offices begins on June 2. The nine million taxpayers who can benefit from Direct Income, the new instant presentation modality, already have the draft available to confirm it in a single click.
As of July 1, taxpayers who have not yet filed the declaration face surcharges of 1% for each month of delay during the first year, plus late payment interest if the Treasury requires them. After the year, the surcharge increases to 15% of the amount.
