An interest-bearing account, a « cuenta remunerada » in Spain, is a bank account that pays interest on the money you leave in it, with no lock-in period. In Spain the gap with a current account is wide: according to the Banco de España, households' overnight deposits earned 0.16% on average in September 2026, while new time deposits paid 2.26%. This guide, written for Spanish tax residents, explains how to read the TAE, which conditions to check, what the deposit guarantee covers and how the interest is taxed.
- 0.16%: the average rate on households' overnight deposits in Spain in September 2026 according to the Banco de España, against 2.26% on new time deposits.
- €100,000 per depositor and per bank: that is what the deposit guarantee scheme covers, in Spain or in another European Union country.
- 19%: the withholding the bank takes from the interest; it is then taxed in the savings base of Spanish income tax (IRPF), from 19% to 30%.
- The headline rate is not enough: check how long it lasts, up to what balance it applies and what conditions it requires.
Leaving money in a current account has a cost that never shows on the statement: €10,000 at 0.16% earns €16 before tax in a year, against €200 at 2%. An interest-bearing account is for money that must stay available, an emergency fund or savings for a near-term plan, without locking it into a time deposit.
This guide does not compare banks or recommend any account. It sets out the criteria for comparing offers, using official figures from the Banco de España, the ECB and the Spanish tax agency, the Agencia Tributaria. For savers in the United States, the closest products are covered in our guide to money market accounts and funds.
TL;DRAn interest-bearing account pays interest on a balance you can withdraw at any time. Before opening one, compare the TAE rather than the nominal rate, and check how long the promotional rate lasts, the maximum balance that earns interest, the conditions required and the fees. The money is covered by the deposit guarantee scheme up to €100,000 per depositor and per bank. In Spain, interest is income from movable capital: the bank withholds 19% and it is declared in the savings base of income tax.
What an interest-bearing account is
An interest-bearing account is an overnight deposit: you can withdraw or transfer the money whenever you like, and the bank pays interest on the balance, usually every month, sometimes every quarter or every year. Many work as a savings account attached to a current account, without their own card or direct debits.
It differs from a time deposit, where the money is locked for an agreed period in exchange for a rate set in advance, and from a money market fund, which is not a deposit but an investment fund.
| Current account | Interest-bearing account | Time deposit | Money market fund | |
|---|---|---|---|---|
| Access | Immediate | Immediate | At maturity (early exit as per contract) | Within a few days |
| Return | Close to zero | Variable, often promotional | Fixed for the term | Tracks money market rates, not guaranteed |
| Deposit guarantee | Yes, up to €100,000 | Yes, up to €100,000 | Yes, up to €100,000 | No, it is an investment fund |
| Tax in Spain | Savings base, 19% withholding | Savings base, 19% withholding | Savings base, 19% withholding | Gain on redemption, savings base |
What accounts pay in Spain in 2026
Account rates follow the European Central Bank's, with a lag and only in part. The ECB raised its deposit facility rate to 2.50% on 10 September 2026 and held it on 29 October. Banks do not pass that rate on to every account: Banco de España statistics show the gap between an average overnight account and a time deposit.
| Average rate in Spain, households (new business) | September 2025 | September 2026 |
|---|---|---|
| Overnight deposits | 0.15% | 0.16% |
| Time deposits, weighted average | 1.66% | 2.26% |
| Time deposits up to one year | 1.69% | 2.29% |
Source: Banco de España, Boletín Estadístico, table 19.7. These rates exclude fees and charges: they show the trend, not a TAE you can compare with an offer. The overnight average is low because it includes current accounts, which pay almost nothing; advertised interest-bearing accounts sit above it, often with conditions attached.
TIN, TAE and how interest is calculated
The TIN, the nominal interest rate, is the rate applied to the balance. The TAE, the annual equivalent rate, adds the effect of how often interest is paid and of any fees: it is the figure Banco de España rules require banks to display, and the one to use when comparing two offers. With monthly payments, the TAE is slightly higher than the TIN.
To estimate what an account earns in a year: balance × TAE. €10,000 at a 2% TAE earns €200 before tax. The bank withholds 19%, or €38, and pays €162 net. The same sum at 0.16%, the average overnight rate, earns €16 before tax and €12.96 net.
Example: what the small print changes
| Offer | Balance | Gross interest over a year | Actual return |
|---|---|---|---|
| Steady 2% TAE | €10,000 | €200 | 2% |
| 3% for the first four months, then 1% | €10,000 | €166.67 | 1.67% |
| 2.5% up to €10,000, 0% above | €30,000 | €250 | 0.83% |
Approximate calculation, without compounding. The highest rate in the advert is not always the one that pays the most: what counts is the average rate over the year and over the balance you actually deposit. To project savings over several years, the compound interest calculator shows the effect of reinvesting the interest.
The conditions to read before opening an account
- How long the rate lasts: many offers pay a high rate for a few months only, or to new customers only. Find out which rate applies afterwards.
- The maximum balance that earns interest: above a cap, the money earns nothing or earns less.
- Linked conditions (« vinculación »): paying in your salary or pension, direct debits, minimum card use or taking out other products. If they are not met, the rate can drop.
- Fees: account maintenance, including on the linked current account, transfers, card. €60 a year in fees wipes out the interest on €3,000 at 2%.
- How interest is paid: monthly, quarterly or yearly. The contract says what happens to interest for the current period if you close the account early.
- The guarantee scheme the bank belongs to, which the contract must state.
This information appears in the pre-contract documents and in the contract. If a condition is unclear, the Banco de España's Portal del Cliente Bancario explains customers' rights and how to complain.
Is the money safe? The deposit guarantee scheme
According to the Banco de España, every deposit opened in Spain must be guaranteed by a scheme covering up to €100,000 per depositor at each bank. The guarantee comes from Spain's Fondo de Garantía de Depósitos or, for a bank authorised in another European Union country, from that country's scheme, with identical cover.
- Per depositor and per bank: all of one person's accounts at the same bank count towards the cap. Spreading money across several banks multiplies the cover.
- Joint accounts: each holder has their own cover. A joint account with two holders and €150,000 is fully covered, €75,000 each, if they have no other deposits at that bank.
- Banks from other EU countries: an account at a European bank operating in Spain is covered by its home country's scheme, up to €100,000. The contract must name the scheme, its address and its website.
- What is not covered: the deposit guarantee does not cover losses on an investment fund, money market funds included, or on shares: they are not deposits.
Adverts for an account must state the scheme the bank belongs to and the amount guaranteed, but membership of the scheme cannot be used as a selling point.
How the interest is taxed in Spain
Interest on an account is income from movable capital, as income from lending your own capital to a third party (article 25.2 of the IRPF law). The bank withholds 19% when it pays the interest and reports it to the Agencia Tributaria, so it appears in the tax data of the draft return. The withholding is a prepayment: in the return, the interest is added to the taxable savings base and taxed on the scale, and the amount already withheld is deducted.
| Taxable savings base | Total rate (state + region) |
|---|---|
| Up to €6,000 | 19% |
| €6,000 to €50,000 | 21% |
| €50,000 to €200,000 | 23% |
| €200,000 to €300,000 | 27% |
| Over €300,000 | 30% |
Scale for the 2025 return (articles 66 and 76 of the IRPF law), half state and half regional, under the common regime; the Basque Country and Navarre set their own scales. For most savers, the 19% withholding matches the final tax: on €200 of interest, €38 is withheld and nothing more is due. With €8,000 of savings income in the year, all savings income combined, the tax comes to €1,560, that is €1,140 on the first €6,000 and €420 on the next €2,000, against €1,520 withheld: €40 is left to pay with the return.
An account at a foreign bank
If the bank does not apply Spanish withholding, the interest arrives gross and a Spanish tax resident must declare it themselves in the savings base. If the combined balance of their accounts held abroad exceeds €50,000 on 31 December or as the average balance of the last quarter, they must also file form 720, according to the Agencia Tributaria.
Interest-bearing account, time deposit or money market fund
An interest-bearing account is the tool for money that must stay available. Its first use is an emergency fund: three to six months of spending. According to the INE household budget survey, a household in Spain spent €35,101 on average in 2025, about €2,925 a month: a three-to-six-month cushion comes to between €8,775 and €17,550 for an average household. Our guide to the 50/30/20 budget rule explains how to work out your own.
A time deposit suits money you will not touch for the term, in exchange for a fixed rate. A money market fund tracks ECB rates closely without depending on a promotional offer, but it is not covered by the deposit guarantee and its value can fall. Long-term money, beyond five years, belongs more in a diversified investment.
Choosing an interest-bearing account in five steps
- Set the amount that must stay available: your emergency fund and the spending of the coming months.
- Compare the average TAE over twelve months, not the opening TAE, on the balance you will actually deposit.
- Subtract the fees and check that the required conditions can be met at no extra cost.
- Check the bank's guarantee scheme and keep no more than €100,000 per depositor at any one bank.
- Review the rate every six months: when the promotion ends or ECB rates change, the offer is no longer the same.
Frequently asked questions
What is a cuenta remunerada?
A Spanish bank account that pays interest on the balance, with the money available at any time. Unlike a time deposit, it does not lock your savings away.
How much does an interest-bearing account pay in Spain in 2026?
It depends on the offer. As a benchmark, the ECB deposit facility rate has been 2.50% since 10 September 2026, and according to the Banco de España new household time deposits paid 2.26% on average in September, against 0.16% for overnight deposits.
Is the interest taxed?
Yes. The bank withholds 19% when it pays the interest. In the return, the interest is taxed in the savings base, from 19% to 30% depending on the amount, and the withholding is deducted.
Is it risky to keep more than €100,000 in one account?
The guarantee scheme covers up to €100,000 per depositor and per bank. Above that, the money is not guaranteed if the bank fails. Spreading it across several banks, or between two holders, widens the cover.
What is the difference between TIN and TAE?
The TIN is the rate applied to the balance. The TAE includes how often interest is paid and any fees: it is the figure to use when comparing.
Do I have to declare an interest-bearing account held outside Spain?
Yes, the interest is declared in the savings base even without Spanish withholding. If accounts abroad exceed €50,000 on 31 December or as the last quarter's average balance, form 720 must also be filed.
