The deadline that counts is almost always your issuer's, not the law's. The card's rules usually leave thirteen months to report a transaction you did not authorise. A dispute with a merchant, by contrast, plays out in weeks. Act as soon as the line appears.
How long do you have to dispute a card payment in Belgium?
It depends on what you are disputing, not on the amount. Three situations give three deadlines, and the shortest is the one your issuer relies on.
| Situation | Deadline | Source |
|---|---|---|
| Transaction you did not authorise (fraud, stolen card) | 13 months from the debit, reporting without delay | Directive (EU) 2015/2366, Art. 71, and the card rules |
| Authorised transaction whose amount was not fixed and exceeds what you could expect | 8 weeks from the debit | Directive (EU) 2015/2366, Arts. 76 and 77 |
| Dispute with a merchant (not delivered, subscription, double charge) | the issuer's deadline, from a few days to a few months | the issuer's form and terms |
In the files I handled in Liège, the confusion always came from the first row. A cardholder read "thirteen months" on a website, waited eleven weeks for a parcel that never came, and found that the file did not fit that box.
What is the difference between the issuer's deadline and the legal thirteen months?
The first frames a dispute, the second an absence of consent. The law does not say that a failing merchant makes the transaction unauthorised: you did pay, you simply did not receive.
The thirteen-month deadline comes from Directive (EU) 2015/2366, known as PSD2, transposed into Book VII of the Code of Economic Law, Belgium's consumer and business code. It assumes you report "without undue delay": thirteen months is a ceiling, not a right to wait. The European text can be read on EUR-Lex.
Chargeback is not in the law. It is a procedure between banks, set by Visa and Mastercard, that the issuer triggers on your behalf. It triggers it within its own deadlines, and it needs documents.
The issuer looks first at the debit date, before the reason. A file that arrives too late for its category is not examined on the substance.
What do the Beobank, ING and Belfius rules say?
They repeat the law on fraud and differ on the rest. Here are the clauses I read, with the version when it is given.
| Issuer and document | Unauthorised transaction | Authorised transaction, amount not fixed | Other deadline written in |
|---|---|---|---|
| Beobank, credit card terms, Art. 11 | 13 months, without delay | 8 weeks for merchant-initiated transactions | presumption of lateness after 2 months |
| ING Visa Classic, rules of 1 January 2025, Arts. 9 and 10 | 13 months after the debit date, written confirmation | 8 weeks, bank answers within 10 working days | deductible of EUR 50 at most before warning |
| Belfius, card rules, Arts. 4 to 6 (no version date) | 13 months after the value date | 8 weeks, answer within 10 working days | 6 days after receiving the statement for some transactions without physical presentation |
I am quoting the rules here, not the cards. The annual fees and APR of those cards do not appear in the documents I read, and a card without those three figures does not enter my cost tables.
The Belfius row deserves a slow read. Article 4 provides that some transactions made without physical presentation of the card or electronic identification are deemed accepted six days after the statement is received. I read this clause as a contractual presumption that does not erase Article 5 on the thirteen months. I cannot tell you how a court or Ombudsfin would treat it: ask your issuer how it applies it.
At Beobank, Article 11 adds a useful sentence: in a disagreement with the merchant, you must settle the dispute directly with it. In other words, the issuer does not guarantee the merchant by contract.
In the files I handled, that referral to the merchant was never the last word. It meant the issuer wanted to see your written attempt before opening a chargeback.
When do Visa and Mastercard open their own deadline?
The networks set a window of about 120 days for most reasons, but it is never held against you directly. It bounds what your issuer can ask of the merchant's bank.
According to a summary published by the payment processor Chargeflow, the 120-day window applies to fraud and consumer-dispute reasons at Visa as at Mastercard, with shorter periods for some processing reasons. It runs from the transaction or the expected delivery date. A ceiling of 540 days would exist for some delayed-delivery cases at Visa. This is a secondary source: the networks' official guides are not fully public, and I have not read them.
The figure to remember here is therefore the gap. Even if the network grants 120 days, your issuer often asks for less to return the form. The two deadlines do not add up: the shortest decides.

What happens if the issuer's deadline has passed?
The issuer can refuse, but it must give reasons. A missed deadline in principle closes the chargeback, not all your recourse.
Write to the complaints department, not the branch. Ask for the exact clause invoked, its version and the date taken as the starting point. At Beobank, acknowledgement of a complaint is announced within five working days and an answer, when the file is complete, aims at fifteen calendar days (Article 23 of the terms).
Here is the order I gave on the phone, with no guarantee of result:
- Dispute right away, even with an incomplete file. The rest can be added later.
- Write to the merchant the same day and keep proof of sending.
- If the issuer refuses for lateness, ask in writing for the starting date it used.
- Go to the complaints department, then to Ombudsfin, the Belgian financial disputes mediator.
According to Test-Achats (16 February 2026), Ombudsfin is free, the problem must be less than a year old, no court proceedings may be under way, and the answer comes in principle within 90 days. Its opinion does not bind the bank.
How much does a delay cost on a disputed line?
Less than the dispute, but not nothing. As long as the line stays in the outstanding balance, it earns interest at the card's rate.
Two Belgian cards, with their three base figures:
| Card | Annual fee | APR on a carried balance | EUR 100 withdrawal | Rate checked at the issuer on |
|---|---|---|---|---|
| Beobank Visa Classic | EUR 5 | 14.49% (EUR 2,150 credit line) | EUR 5.00 | 20 October 2026, withdrawal checked on 18 September 2026 |
| Buy Way Mastercard One | EUR 17.50 | 14.50% (variable borrowing rate of 13.75%) | EUR 6.50 | 20 October 2026 (September 2025 guide) |
Take a disputed line of EUR 250 that stays on a card at 14.49%. The equivalent monthly rate is about 1.13%. For a file that drags on three months, that is about EUR 8.60 of interest. Over six months, about EUR 17.50. These amounts are my calculations, with no new purchase or refund in between.
The sum is not the point. The point is that a disputed amount does not release you from paying the statement on its date, until the issuer has confirmed in writing that it puts the line on hold. If the amount strains your budget, talk early to an approved debt mediation service or to your local CPAS (the public social welfare centre). This article does not replace advice suited to your situation. The carried-balance mechanism is detailed in the article on the minimum payment.
Which dates and documents should you note for the file to hold?
Four dated markers, nothing more. This is the list I asked for before opening a file:
- the purchase date, the debit date on the statement, and the promised delivery date;
- the date of your first message to the merchant, with its reply or its silence;
- the date you received the statement on which you saw the line;
- the annotated statement, the order confirmation, and the written trace of your approach to the merchant.
Statements are monthly: a line dated the 2nd of the month is only visible on the next statement. Beobank specifies that the payment due date on the statement falls at least 15 days after it is generated.
For a parcel that never arrived or a merchant that closed, see the article on the bankrupt or non-delivering merchant. For a subscription billed after cancelling, the one on the double charge and cancelled subscription. For a line you do not recognise, the hacked card and the refusal for gross negligence have their own rules, and the general mechanism of chargeback in Belgium completes this one.
Three points I could not verify
Beobank's form dates from 2021 and its current page publishes no return deadline: ask for the version in force. The Belfius rules carry no readable version date, and I do not quote the fee or APR of its cards, absent from the documents read. Finally, Visa's and Mastercard's official deadlines are not fully public: the 120-day figure comes from a secondary summary, to be confirmed with your issuer.
To compare cards on what they cost rather than on their promises, the ranking of Belgian credit cards, the comparison tool and the choice guide start from the same checked rates.

Frequently asked questions
Delphine a passé sept ans au service litiges et rétrofacturation d’un émetteur de cartes belge, à Liège, entre 2015 et 2022 : le bureau où atterrissent les contestations de porteurs, les retraits facturés deux fois et les cautions d’hôtel qui restent bloquées trois semaines. Elle a donc lu, ligne par ligne, plusieurs milliers de relevés de cartes belges, et elle sait où se logent les montants que personne ne regarde avant de signer. Depuis 2023 elle relève chaque trimestre les tarifs publiés des émetteurs belges et tient le tableau de coûts qui sert de base à ce site. Ce qui l’agace : les brochures qui annoncent une carte à 0 € sans mentionner que le premier retrait au distributeur coûte 5 € fixes plus 1,8 % de commission, et que les intérêts courent dès le jour du retrait.
