Within a week of arriving in Spain, someone will ask you to “hacer un Bizum”. Splitting a dinner bill, paying your share of a birthday present or settling up with the padel group – Spaniards send small amounts by phone all the time. This guide is for newcomers who want to join in. You will learn how Bizum works, how to set it up, what the 2026 tax reporting rules mean for you, how to avoid the common scams and which other mobile payment options are widely used.

What Bizum is and how it works

Bizum is an instant payment service created by Spanish banks. It lives inside your bank’s own app: you send money to a mobile phone number instead of an IBAN, and it lands in the other person’s bank account within seconds. There is no separate wallet to top up – the money moves straight from account to account.

• Send money: choose a contact, enter the amount and a short concept, then confirm.
• Request money: ask a contact to pay you. They must accept the request before any money moves.
• Pay online: many Spanish web shops offer Bizum at checkout – you confirm the payment in your bank app instead of typing card details.
• Donate: many charities and NGOs accept donations by Bizum.

For everyday use between people it is generally free, but your bank sets the conditions, so check your account terms.

How to set up Bizum

You need an account at a bank that offers Bizum – most traditional Spanish banks do, as well as some online banks with a Spanish IBAN. Foreign accounts and many international money apps do not support it, so check before you choose a bank. Our guides on opening a bank account and the best banks for expats can help.

1. Get a Spanish mobile number. Most banks link Bizum to a Spanish number – see our guide to mobile providers.
2. Open your bank app and look for “Bizum” in the menu or payments section.
3. Register your phone number and choose the account Bizum should use.
4. Accept the terms and confirm with the code your bank sends you.
5. Check your limits in the app. Bizum and each bank set maximum amounts per payment, per day and per month. If you need to move a large sum, use a normal bank transfer instead.

Each phone number can be linked to one account at a time. If you change bank, deregister Bizum at the old one first, then register at the new one.

Bizum and Hacienda: what changed in 2026

Headlines about “Hacienda watching Bizum” worried many people. Here is what actually changed:

• The rule: Royal Decree 253/2025 updated the information that banks and payment providers must send to the Agencia Tributaria. The new obligations apply from 1 January 2026.
• Who is reported: businesses and professionals (empresarios and profesionales) who receive payments by Bizum. Banks send monthly, aggregated figures – not every single payment.
• Private individuals: Bizum payments between friends and family are not part of this reporting, and Hacienda has stated that Bizum payments between private individuals do not have to be declared.

One important caveat: income is income, whatever the payment method. If you are self-employed, rent out a room or sell things as a regular activity, money received by Bizum must be declared like any other income. If you are unsure, read our guide to the Spanish tax system and ask a gestor.

How to avoid Bizum scams

Bizum payments are instant and usually cannot be reversed, which makes them attractive to fraudsters. The most common tricks:

• The fake “request”: a buyer on a second-hand app says they will “send you a Bizum”, but actually sends a request. If you accept it, you pay them. Read every screen carefully – a request asks you to send money.
• Fake bank calls or texts: nobody from your bank will ask for your passwords or confirmation codes. Hang up and call the number on your card.
• “Wrong number” payments: a stranger says they sent you money by mistake and asks you to return it. Check your actual account balance and contact your bank instead of sending anything.
• Deposits for flats or cars you have not seen: never pay a deposit by Bizum to someone you have not met for something you have not checked. Our renting guide explains safer ways to pay.

If you are scammed, contact your bank immediately and report it to the police – the sooner, the better the chance of stopping the money.

Other mobile payments in Spain

Bizum is for paying people and some web shops. In physical shops, other methods dominate:

Carry a little cash anyway: some small bars, market stalls and village shops prefer it, and card terminals occasionally fail. Our cultural differences guide covers other everyday surprises.

Whether you are paying a mortgage back home, supporting family, moving savings for a property purchase or simply paying a bill in another country, sending money out of Spain can cost far more than it needs to. This guide compares the main types of provider in a neutral way, explains where the hidden costs are and shows how to work out the real price of a transfer before you send it.

First question: euros or another currency?

The cost of a transfer depends far more on where the money is going and in which currency than on which bank you use.

Euros to another SEPA country

If you send euros to an account in another country of the Single Euro Payments Area (SEPA), which includes the EU and countries such as Norway, Switzerland and the UK, the transfer works like a domestic one. Under EU rules, a cross-border euro transfer within the EU cannot cost more than the same transfer inside Spain, and many Spanish banks do not charge for online transfers at all.

Two newer EU rules also help:

• Instant transfers at the same price: since 9 January 2025, banks in the euro area cannot charge more for an instant euro transfer than for a standard one. Instant transfers arrive within seconds, every day of the year.
• Verification of payee: since 9 October 2025, your bank must check whether the name you enter matches the IBAN before you send, and warn you if it does not. This helps protect you from scams.

Branch transfers can still carry a fee, so doing it in your app or online banking is usually cheapest.

Other currencies or countries outside SEPA

Sending money to the US, Morocco, Colombia or anywhere in another currency, including pounds to a UK account, is where costs add up. You may pay:

• An upfront fee charged by your provider.
• An exchange-rate margin: the difference between the rate you get and the mid-market rate (the rate you see on financial news sites). This is often the biggest cost and the least visible.
• Intermediary and receiving fees: international SWIFT transfers can pass through correspondent banks that take a cut, and the receiving bank may charge too.

When a bank asks who pays the charges, the usual options are SHA (shared: you pay your bank, the recipient pays theirs), OUR (you pay all charges) and BEN (the recipient pays everything). If the exact amount must arrive, for example a rent or invoice, check which option you choose.

The main types of provider compared

Fees and rates change constantly and depend on the amount and destination, so this table compares how each type of provider usually works rather than quoting prices.

No single type is always cheapest. For a small monthly amount to a family member, an online service or app may win. For €200,000 towards a property, a bank or broker quote may beat both. If you have not yet chosen a Spanish bank, see our guides to opening a bank account in Spain and traditional and online banks for expats.

How to compare the real cost

1. Decide the exact amount you want to send and the currency the recipient needs.
2. Check the current mid-market rate on a neutral financial site.
3. Ask each provider for a quote showing the amount the recipient will receive, after all fees.
4. Compare that figure, not the advertised fee. A “no fee” offer with a poor exchange rate can be the most expensive option.
5. Check delivery time and whether the receiving bank charges for incoming international payments.

For transfers between EU currencies, providers have to show you the currency conversion charge before you confirm, which makes comparing easier.

Safety: check the provider is authorised

Any company that moves money for you in Spain must be authorised as a bank, payment institution or electronic money institution, either by the Banco de España or by another EU supervisor. You can check this in the Banco de España’s register of entities; for firms from other EU countries, the European Banking Authority’s register applies.

• Never send money to someone you have only met online, or because of an urgent call or message claiming to be your bank.
• Take the verification of payee warning seriously; transfers are hard to reverse once sent.
• For property purchases, confirm bank details by phone with your lawyer or notary using a number you already know, not one in an email.

Large amounts, paperwork and tax

Under anti-money-laundering rules, banks and transfer services can ask where large sums come from. Keep documents such as a sale contract, payslips or an inheritance deed to hand to avoid delays.

Sending money abroad is not taxed as such, but the money itself may have tax consequences: gifts can fall under Spanish gift tax depending on the region, and if you are tax resident with accounts abroad you may need to report them on Modelo 720. Carrying cash instead of transferring it is rarely a good idea: amounts of €10,000 or more entering or leaving Spain must be declared to the authorities.

A letter from the Agencia Tributaria (AEAT) can be unsettling, especially if you are still learning how Spanish taxes work. This guide is for foreign residents, freelancers and property owners who have been contacted by the Spanish tax office, or want to be prepared. You will learn the difference between a simple check and a full inspection, how to respond, which deadlines matter and how to appeal.

Audit, check or inspection: what is the difference?

Most contact from the tax office is not a full audit. Spanish tax law (Ley 58/2003, General Tributaria) sets out several procedures, and it helps to know which one you are in, because the rules and time limits differ.

• Requerimiento (request for information): the office asks you to send a document or explain an item on your return. Often this is the whole matter.
• Comprobación limitada (limited check): a desk review by the management department, usually about specific items such as a deduction, rental income or a missing return. The maximum duration is six months.
• Inspección (inspection): a deeper review carried out by the inspection department, which can cover several taxes and years. The general maximum duration is 18 months, extended to 27 months in certain larger or more complex cases.

The letter you receive states which procedure has been opened, which tax and which years are covered. Read that part first.

Why foreigners get contacted

Foreigners are not targeted as a group, but some situations are more likely to trigger questions. The tax office cross-checks your return with data from banks, employers, notaries, land registries and, through automatic exchange of information, tax authorities in other countries.

• Foreign income (pensions, salaries, dividends) that does not appear on your Spanish return
• Foreign bank accounts or assets that were not declared on Modelo 720 when required
• Rental income from a Spanish property that was not declared, or non-resident tax that was not paid
• Doubts about your tax residence, for example if you spend more than 183 days a year in Spain but file as a non-resident
• Freelance (autónomo) invoices and VAT returns that do not match each other

How to respond step by step

1. Check that it is genuine. Official notifications arrive by registered post or in your electronic mailbox at the AEAT Sede or DEHú. Be wary of emails or text messages asking you to click a link or pay; the tax office does not ask for card details that way.
2. Note the deadline. The letter states how long you have to reply, often ten working days for a request for documents. If you are signed up for electronic notifications (mandatory for companies), a notification you do not open within ten calendar days is treated as delivered, so the deadline still runs.
3. Gather the documents asked for and nothing more than what is relevant. Keep copies of everything you hand over.
4. Reply through the official channel mentioned in the letter, usually the online Sede using your digital certificate, Cl@ve or a reference number, or in person with an appointment. Keep the registration receipt.
5. Ask for more time if you need it. You can request an extension before the deadline ends, explaining why (for example, waiting for documents from abroad).
6. Read the proposal carefully. At the end of a check you normally receive a proposal (propuesta de liquidación) and a period to submit comments (alegaciones) before the final decision.

Documents you may be asked for

• Spanish and foreign bank statements
• Employment contracts, payslips, pension statements or freelance invoices
• Proof of residence: padrón certificate, rental contract, utility bills, travel records
• A tax residence certificate from another country, if you claim to be resident there
• Purchase and sale deeds, receipts for deductible expenses and proof of foreign tax paid

The general limitation period for tax debts in Spain is four years, so keep your records for at least that long, counted from the end of the filing period of each return. Keep documents about property purchases and investments for as long as you own the asset, plus four years.

Possible outcomes and how to appeal

A check can end with no changes, or with an assessment (liquidación) of extra tax plus late-payment interest. If the office considers that you committed a tax offence, a separate penalty procedure is opened. Penalties can be reduced if you accept the assessment and pay within the deadline, so ask your adviser to calculate this before deciding whether to agree.

Appealing does not automatically stop the debt from being collected. To suspend payment while you appeal, you normally have to request it and offer a guarantee.

Modelo 720 and foreign assets

Tax residents must file Modelo 720 by 31 March if they hold more than 50,000 euros in one of three categories abroad: bank accounts, securities and investments, or real estate. In January 2022 the Court of Justice of the European Union ruled that the old, very high fixed penalties for late or missing 720 returns broke EU law, and Spain changed the system. However, undeclared foreign income can still be assessed, so if you have missed a 720 or not declared foreign income, get advice and consider correcting it voluntarily before the tax office contacts you.

Practical tips for expats

• Never ignore a letter, even if you have moved abroad. Keep your address up to date with the tax office.
• Get a digital certificate or Cl@ve so you can read notifications and reply online.
• Use a qualified adviser (asesor fiscal, gestor or tax lawyer) for inspections or anything involving foreign income. Many work in English.
• Stay factual and polite. Answer exactly what is asked and put your explanations in writing.
