In short: Bizum and Hacienda in Spain: in the rules we reviewed there is no notice to the AEAT (the Spanish tax agency, Hacienda at state level) for each Bizum or each transfer from your family. Banks do send it data on your accounts (balances and yearly totals of debits and credits), cash deposits and withdrawals of more than €3,000, and what businesses collect by card or by mobile. If your bank asks where the money comes from, that is anti-money-laundering, not a tax. The tax appears when the money is a gift: a donation is taxed under the inheritance and gift tax (ISD), and we found no exempt minimum amount in the state law.
Who sees what
There are three separate layers. The bank applies the anti-money-laundering law and sees everything that goes through your account. The AEAT receives from banks only what the rules in the table require. The SEPBLAC (the Executive Service of the Commission for the Prevention of Money Laundering) receives alerts about suspicious operations and some monthly reports.
| Who | What it sees or does | When | Rule |
|---|---|---|---|
| Your bank | Asks what you use the account for and where the money comes from, and monitors your operations | Always, no minimum amount | Law 10/2010, arts. 5 and 6 |
| Your bank | If it cannot apply those measures it does not carry out the operation; if it sees signs of money laundering it informs the SEPBLAC and does not tell you | No minimum amount | Law 10/2010, arts. 7.3, 17, 18 and 24 |
| AEAT | Receives from banks, for each account: holders, balance on 31 December, average balance of the last quarter and total debits and credits of the year | Every year, no minimum amount | RD 1065/2007, art. 37 |
| AEAT | Deposits, withdrawals and payments in banknotes or coins | Every year, if the operation is more than €3,000 | RD 1065/2007, art. 38.1.b |
| AEAT | What businesses and professionals collect by card or by "payments associated with a mobile phone number" (the rule does not name Bizum) | Every month, with the amount invoiced | RD 1065/2007, art. 38 bis |
| AEAT | Card operations: top-ups, charges and cash withdrawals | Every year, except cards with less than €25,000 in debits and in credits that year | RD 1065/2007, art. 38 ter |
| SEPBLAC | Operations with physical movement of cash, traveller's cheques or bearer cheques that do not go through a client's account | Every month, if more than €30,000 | RD 304/2014, art. 27.1.a |
"Cash" has a precise meaning here. For the limit in Law 7/2012, cash means the payment means in art. 34 of Law 10/2010: banknotes and coins, cheques and other bearer documents, non-nominative prepaid cards and highly liquid commodities such as gold. A transfer or a Bizum is not cash.
Limits and duties that are yours
| Situation | Limit or rule | Rule |
|---|---|---|
| Paying or collecting in cash when one party acts as a business owner or professional | Banned from €1,000 (€10,000 if the payer is an individual with no tax domicile in Spain who does not act as a business owner). Fine of 25 % of what was paid in cash; the payer and the receiver are both liable | Law 7/2012, art. 7 |
| Entering or leaving Spain with cash or bearer cheques | Prior declaration from €10,000 | Law 10/2010, art. 34.1.a |
| Moving those payment means inside Spain | Prior declaration from €100,000 | Law 10/2010, art. 34.1.b |
| Receiving money without giving anything in return | An acquisition free of charge, the taxable event of the ISD. We found no exempt minimum amount in the law | Law 29/1987, art. 3 |
| Having accounts or property abroad | You declare them yourself on the Modelo 720 if a block exceeds €50,000 on 31 December | Modelo 720 |
Three ideas that circulate and what the rule says
- "A Bizum of more than €10,000 is reported to Hacienda." The rules we reviewed have no such threshold for Bizum or for transfers. The €10,000 in Law 10/2010 is for entering or leaving Spain with cash or other physical payment means. Separately, a bank may report a suspicious operation of any amount.
- "A gift up to a certain amount is not taxed." We found no such limit in Law 29/1987. In the Comunitat Valenciana, between parents and children, what exists is a reduction of €100,000 and a 99 % relief, with conditions: see the gift card.
- "My bank blocked a transfer from Ukraine, so it is a tax." No: it is the due diligence of Law 10/2010. A bank must not carry out the operation if it cannot apply those measures (art. 7.3) and may not tell you whether it reported (art. 24).
Four common situations
- Your parents send you money for the rent. According to the rules we reviewed, the transfer does not trigger its own notice to the AEAT, but the bank may ask where the money comes from. For the tax, what matters is what that money is. A one-off payment with no repayment is a gift (ISD). If you reside in the Comunitat Valenciana and it comes from your parents, the gift card explains the public document, the origin of the money and the Modelo 651 within one month. A monthly allowance to live on may be maintenance and not a gift: it is a grey area.
- A friend pays you back by Bizum. A Bizum is a bank payment, not cash, so the €1,000 limit does not apply. If you lent that money earlier, receiving the repayment is not receiving something for free, and the ISD taxes only what is received free of charge. Keep proof of the loan (the Bizum or the transfer you sent) and write a clear description on the repayment. If it is really a gift, the above applies.
- You sell your car and are paid in cash. The €1,000 limit of Law 7/2012 applies if one party acts as a business owner or professional, for example a dealer. Between two individuals, the text of that article does not cover it. If you deposit the cash, the bank reports to the AEAT every year the cash deposits of more than €3,000 and may ask for the origin: keep the signed sale contract. A sale between individuals may be subject to transfer tax, paid by the buyer (consolidated text, arts. 7.1.A and 8), and the sale may have effects on your tax return; this card calculates neither.
- You bring to Spain the money from selling a flat in Ukraine. If it is your own money, it is not a gift, but the bank will ask for its origin: have the sale contract and proof of payment. The sale may have tax effects in Spain if you are a tax resident: see the tax return for foreign residents and the double taxation relief. If what your mother sends is the money from selling her flat, it is a gift and the gift card applies. If you keep accounts or property in Ukraine on 31 December, see the Modelo 720 (more than €50,000 in one block).
What to do
- Decide what the money is before sending or receiving it: a gift, a loan to be repaid, payment for something you sold, or help to live on. The procedure depends on it.
- Gift: it is a donation. See the gift card (public document, origin of the money and Modelo 651 within one month, for residents of the Comunitat Valenciana). In another region, the rules of yours apply.
- Loan: put it in writing (amount, date and repayment term) with both parties' signatures and keep the transfers out and back.
- Sale: keep the contract and proof of payment. With a business owner or professional, pay and collect through the bank from €1,000.
- Money from another country: use a transfer to your account, which leaves a trail, and have proof of the origin ready. If a document is in another language, ask your bank whether it needs a translation.
- Receipts: keep the bank ones for at least 5 years, the period set by Law 7/2012 for payments with business owners and professionals.
- Accounts or property outside Spain: check the Modelo 720.
Documents
- Bank receipts for the transfer or the Bizum, with a clear description.
- The gift document (notarial deed), if it is a gift: see the gift card.
- The loan contract with amount, date and repayment term, signed by both parties, if it is a loan.
- The sale contract and proof of payment, if you sold a car, a flat or another asset.
- Proof of the origin of the money, depending on the case (usual examples, no official list): statements, an income certificate, a sale contract.
Indicative list: your bank may ask for other documents depending on the case.
Grey areas and cases where this does not help
- Monthly allowance to live on. It may be seen as maintenance and not as a gift. In our July 2026 review we did not find a DGT ruling that settles this for adults: it is a grey area. Ask an adviser and keep proof.
- Small gifts (a birthday, a wedding). We found no exempt minimum in Law 29/1987, but how it applies to small gifts of social custom we have not verified in an official source. We do not treat it as confirmed.
- Loan between relatives. A loan is a loan if there is a real duty to repay. If the money is neither repaid nor expected to be, its nature may be different. We found no official criterion that settles it: ask an adviser.
- Modelo 600. The consolidated text of the transfer and stamp tax (ITP and AJD) lists loans among the taxable acts (art. 7.1.B) and declares them exempt (art. 45.I.B.15). Whether the form must be filed even when the operation is exempt, we have not confirmed: ask at the tax office of your region.
- Fundraisers or money from several people to your personal card. Each person may count as a donor and, without a family tie, the Comunitat Valenciana gives no reduction or relief. It is a grey area: ask before.
- A specific review. This card covers what banks report by rule. In a review of your case, the AEAT may ask for more information; that has not been reviewed here.
- If you do not reside in Spain, this card does not apply: ask an adviser.
