Can I use an online bank like N26 or Revolut to pay Portuguese taxes?

You open the Portal das Finanças, find your IRS or IMI payment document, and see an Entidade number and a long Referência code. Then you open your Revolut or N26 app and find nowhere to type them. This guide explains which online banks can pay Portuguese taxes, which methods actually work, and the fallback options when your neobank comes up short.

How Portuguese Tax Payments Actually Work

When I paid my first tax bill in Portugal, I assumed I could send a bank transfer to “the tax office” the way I would with a utility company back home. That is not how the Autoridade Tributária, usually just called Finanças, is set up. Before deciding whether your online bank can do the job, it helps to know what Finanças is asking you to do.

The Payment Document and Its Reference

Almost every tax payment starts with a payment document, sometimes called a documento de cobrança or guia de pagamento. You download it from your area on the portal. That applies to an IRS balance after filing, an IMI property tax instalment, the annual IUC car tax, or a fine. If you have never used the portal, see The Portuguese Tax Authority Portal (Portal das Finanças).

The document shows three key pieces of information:

• Entidade: the entity code that identifies the payee
• Referência: a unique reference tied to your specific debt
• Montante: the exact amount due

Together these form a Multibanco-style payment reference. The reference is tied to one specific tax, one amount and one deadline. Pay a different amount, or pay after the deadline, and the reference may no longer work. To understand why Portugal leans on this reference system so heavily, see The Multibanco System and MB Way: Portugal’s Unique Payment Network.

Why Neobanks Sometimes Struggle Here

Paying a reference is a local Portuguese feature. Banks such as Millennium bcp, Caixa Geral de Depósitos, Novobanco and ActivoBank include a “Pagamentos ao Estado” or “Pagamento de Serviços” option in their apps, because they plug directly into the SIBS network behind Multibanco.

Pan-European neobanks were built around SEPA transfers and card payments, not around Portugal’s domestic reference system. Revolut has invested in Portugal and has added local features for Portuguese customers over time. N26 is designed as a Europe-wide product run from Germany. Whether your app shows a Multibanco payment option depends on the provider, your account country and the version of the app you have. Open your app, look for “Pagamentos de Serviços”, “Multibanco” or “Pay a reference”, and see what is actually there.

The Main Routes to Pay

Finanças accepts payment through several channels. Here is how each one tends to work for someone banking mainly with a neobank:

Payment route	What you need	Works with N26 or Revolut?	Best for
Multibanco ATM, “Pagamentos ao Estado”	Any card the ATM accepts for that function, plus Entidade and Referência	Depends on whether the ATM lets a foreign-issued card use the payments menu	Quick one-off payments in person
Portuguese bank app, payments menu	An account at a Portuguese bank	Only if your neobank offers a Multibanco references feature	Paying from home in two minutes
Bank transfer using the details on the document	The IBAN and reference wording Finanças provides for transfers	Generally yes, as a standard SEPA euro transfer	People without a Portuguese bank
Direct debit set up on Portal das Finanças	A SEPA IBAN in your name that accepts direct debits	Often yes, but confirm your account accepts mandates	Recurring taxes like IMI and IUC
CTT post office counter	The payment document	Yes, pay at the counter	Anyone who prefers paying in person

Using N26 and Revolut in Practice

We walk through the scenarios that most often come up for people in this situation. Most of them ended in a payment that went through, sometimes after a bit of muttering at the screen.

Paying a Reference Directly in the App

If your Revolut app shows a Multibanco or services payment option for Portuguese references, the process is the same as at any local bank:

1. Download the payment document from Portal das Finanças and keep it open.
2. In your banking app, open the services or Multibanco payments section.
3. Enter the Entidade exactly as shown.
4. Enter the Referência, checking every digit, since one wrong digit can send it to a different debt or get rejected.
5. Enter the exact Montante. Do not round it.
6. Confirm, then save or screenshot the receipt.
7. Wait a few working days and check the portal, where the debt should show as paid.

If you bank with N26, or your Revolut account has no such option, do not force it. Use one of the routes below.

Paying by SEPA Transfer

This is the route that rescues most neobank users. For some tax payments, particularly when the taxpayer is paying from an account outside Portugal, Finanças provides transfer details: an IBAN for the Portuguese Treasury and the reference text to include in the transfer description. Because N26, Revolut and Wise can all send standard SEPA euro transfers, this route works with any of them.

A few habits will save you trouble:

• Copy the IBAN and reference wording exactly as Finanças shows it, from the official document or the portal’s payment instructions, never from a forum post or an email.
• Put the payment reference in the description field exactly as instructed, because that is how Finanças matches your money to your debt.
• Send the exact amount, in euros, from an account in your name.
• Pay well before the deadline. SEPA transfers are usually quick, but a weekend or public holiday can add time, and Finanças counts the date the money arrives.
• Keep the transfer confirmation from your app until the portal shows the debt as settled.

If your income arrives in another currency, think about the conversion step before you pay. A friend of mine kept his savings in pounds and paid his IMI with Wise. He converted the exact euro amount first, then sent the transfer from his euro balance, so he knew the precise sum leaving his account.

Walking to a Multibanco ATM

Sometimes the fastest fix is to walk to the nearest Multibanco machine, choose “Pagamentos ao Estado” or the services menu, and type in the reference. Foreign-issued cards do not always get access to these menus. Some cards can withdraw cash but are blocked from the payments functions, and the outcome can vary between cards and machines.

A Portuguese-issued debit card is the most reliable option at an ATM. Depending on how your neobank account is set up, your card may count as one. If you plan to pay at a machine, try a small, low-stakes payment first, such as a utility reference, so you are not experimenting on the day your IRS bill is due. For a step-by-step walkthrough of the ATM menus, see How to use the Multibanco ATM network to pay taxes, tolls, and utility bills.

MB Way is the other tool locals use, and it does not always cooperate with a foreign phone number or card. If you have run into that, see Linking your foreign phone number to MB Way (and why it usually fails).

Direct Debits, Refunds and the IBAN on Your Tax Profile

Paying one bill is the easy part. The longer-term question is whether Finanças will work with your neobank on autopilot, both when collecting money and when sending it back to you.

Setting Up Direct Debit for IMI, IUC and IRS

Portal das Finanças lets you authorise a direct debit, a débito direto, for certain recurring taxes. Once it is set up, the tax is collected automatically on the due date. This is very convenient for IMI if you own property and for IUC if you own a car.

Under SEPA rules, a euro direct debit should be possible from any SEPA account, whatever country code the IBAN starts with. In practice, a few things can go wrong:

• Your IBAN may start with a code from another EU country, such as LT or DE. That should be valid, but now and then a system rejects it at setup, and you may need to try again or contact Finanças.
• Some neobank accounts need you to approve or allow direct debit mandates inside the app. If you skip that step, the first collection can bounce.
• If the debit fails, the tax remains unpaid, and late interest and possibly a fine can follow.

Revolut has offered Portuguese IBANs to some customers, while N26 has historically issued German ones. Check what your own account shows. To learn how mandates are managed inside a banking app, see Paying utility bills automatically: Setting up SEPA Direct Debits on your bank app.

If you hold property, set a calendar reminder for each IMI instalment anyway, and check after each due date that the money actually left. If a payment slips through the cracks, see What happens if you forget to pay your IMI property tax on time?. Car owners should do the same with IUC, which is due around the registration anniversary. See Paying your car tax (IUC) online before your vehicle’s registration anniversary.

Getting Your IRS Refund Into a Neobank

Many residents end up with a reembolso, a refund, after filing the annual return. Finanças pays refunds into the IBAN registered on your tax profile, so that IBAN needs to be correct, active and in your own name. If you have not yet filed, see Filing the Annual IRS Tax Return (Modelo 3): Deadlines and Process.

To register or change your IBAN, go to your personal data area on the portal. Depending on the type of change, Finanças may ask for proof that the account is yours, such as a bank statement or account certificate showing your name and IBAN. Most neobanks let you download this from the app as a PDF.

A friend of mine in Setúbal had her refund delayed for weeks because the IBAN on her profile belonged to a Portuguese account she had closed. Updating it fixed the problem, but only for future refunds. Before you close any bank account, update the IBAN on your tax profile first. If you are moving away, see Getting an IRS tax refund (Reembolso) deposited after you have left Portugal.

Fines and Smaller Bills

Traffic fines, late filing penalties and similar items also produce a payment document with a reference, and you can use the same routes described above. To get the reference for a fine, see How to pay a Portuguese traffic fine (Multa) using the Portal das Finanças.

Building a Setup That Will Not Let You Down

After years of juggling accounts, here is the realistic setup I recommend to friends.

Keep One Portuguese-Friendly Account

Neobanks are excellent for spending, travel and currency exchange. Taxes, though, are where Portugal’s local infrastructure matters most. Many expats keep N26 or Revolut for everyday life and open a low-maintenance Portuguese account just for references, direct debits and refunds.

ActivoBank and Moey! are popular for this because they are digital-first and also fully plugged into Multibanco. To compare the options, see Online and Neobanks in Portugal: ActivoBank, Moey!, Revolut, and N26.

If you want to stay neobank-only, you can. Just learn the SEPA transfer route and the CTT counter option before you need them.

Plan for Investment Income Before the Bill Arrives

A tax bill is a cash bill, and it has to be paid in euros. Many expats hold savings or ETFs with a broker such as Trade Republic, or crypto on an exchange like Binance. Finanças will not accept shares or tokens. If gains, dividends or crypto disposals mean you owe tax, plan to sell and move the euros to your paying account early. Sales take time to settle, withdrawals can take longer, and some exchanges hold transfers for checks.

For example, someone sells crypto in late spring, sees the euro withdrawal held for review, and runs too close to the payment deadline. A buffer of a couple of weeks removes that stress.

When the Bill Is Too Big to Pay at Once

If the amount is more than you can pay in one go, you do not need to panic or borrow at a bad rate. Finanças allows payment in instalments for certain debts, applied for through the portal, and the rules depend on the size and type of debt. See Requesting a payment plan for a large IRS tax bill in Portugal for the process.

My quick checklist before every tax payment:

1. Download the official payment document from the portal.
2. Check the deadline and the exact amount.
3. Choose your route: in-app reference, SEPA transfer, ATM or CTT counter.
4. Make sure the euros are in the paying account, converted in advance if needed.
5. Pay, and keep the receipt.
6. Check the portal a few days later to confirm the debt shows as paid.
