Banks will inform the Treasury in January, for the first time, of cards with 25,000 euros or more in charges or credits during 2026, but withdrawing money from the ATM continues without a fine

The Tax Agency receives information about their clients’ money every year from banks through so-called informative declarations (they are presented by the entities themselves, without the client doing anything), and in January 2027 a new one is released. This is model 174, with which banks and card issuers will report all cards that have added 25,000 euros or more in charges or credits throughout 2026.

This is established in article 38 ter of the General Regulation of tax management and inspection, added by Royal Decree 253/2025, which only excludes cards “whose total amount of charges and whose total amount of credits registered in the year have been less than 25,000 euros.” Order HAC/747/2025 establishes in its article 17 that it is presented between January 1 and 31 of the following year, and in its third final provision that the first will be that of January 2027, with the data for 2026.

Enter any card, physical or virtual, debit, credit or electronic money. For each one, the bank will give the number and total amount for the year of charges, credits, cash top-ups, purchases in stores and withdrawals (not each operation separately), in addition to the associated account, if there is one, and its owners and authorized persons.

What happens to cash, 500 bills and Bizum

Withdrawing or depositing money in the bank does not have any fine, since the bank communicates every year, in form 171, “the impositions, dispositions of funds and the collections of any document, which are made in metallic currency or bank notes when their amount is greater than 3,000 euros”, according to article 38 of the same regulation.

That is to say, an operation of just 3,000 euros does not enter and one of 3,001 does, although only as information that the bank communicates to the Treasury. The law itself that limits cash payments clarifies that this limitation “will not be applicable to payments and deposits made in credit institutions” (article 7 of Law 7/2012).

Another thing is the anti-laundering controls, which the bank has to apply if it sees signs regardless of the amount, and which allow it to ask for justification of where the money comes from and force it not to carry out the operation if it cannot complete them (can be read in article 7 of Law 10/2010).

The 500 euro banknotes do not have their own declaration, since they fall into model 171 like the rest of the cash, and they remain legal tender although they stopped being issued in 2019, according to the European Central Bank.

In the case of Bizum, since January 2026, banks have reported each month on what business owners and professionals charge by card and by mobile phone, without a minimum amount (form 170), while charges between individuals “are excluded”, according to the frequently asked questions of form 170 of the Tax Agency.

When is there a fine for paying in cash

What does have a fine is paying 1,000 euros or more in cash when one of the two parties is a businessman or professional (the limit has been in force since July 2021; before it was 2,500 euros), with a penalty of 25% of what was paid for which both parties are responsible, according to the same article 7 of Law 7/2012 (the cases in which it is not possible to pay in cash are reviewed here).

For example, paying 3,000 euros in bills to a self-employed plumber entails a fine of 750 euros, which is reduced by half if it is paid once the proposed sanction has been notified and before the resolution, waiving the need to present allegations. According to the same article, only the person who first reports the transaction to the Tax Agency is exempt, within three months following the payment and with the amount and identity of the other party, and if both report at the same time, neither is exempt.

If the Treasury detects money that does not match what was declared, it can treat it as an unjustified capital gain and add it to the general income tax base, according to article 39 of the Personal Income Tax Law, unless the taxpayer proves that this money was already his before the limitation period.
