You buy and sell securities from your Revolut app, the interface is smooth, everything seems taken care of. But one piece is missing, and it’s not a trivial one: the stock-exchange tax (TOB). On Revolut, it is neither computed nor withheld for you. The Belgian-resident investor is solely responsible for it.
This nuance is easy to miss, and that’s precisely what makes it dangerous. Many users assume, by reflex, that their platform does what’s needed — the way a Belgian bank would. With Revolut, that’s not the case. The obligation doesn’t disappear for all that: it rests entirely on your shoulders, with a risk of fines and late-payment interest if it’s overlooked.
In Belgium, every purchase or sale of securities triggers the TOB. The real question isn’t whether you owe it — it’s who handles it. And the answer depends entirely on your platform.
An intermediary established in Belgium is legally liable for the TOB: it withholds and pays it for you. An intermediary established abroad is not. So it is you, the Belgian-resident investor, who must declare and pay it — unless you can prove it has already been paid.
This is where Revolut stands apart. Among the major online investment apps, some players established in Belgium handle it automatically. Saxo, for example, has a Belgian branch and withholds the TOB for its clients. Revolut, on the other hand, is among the platforms that do not withhold it. The result: for you, it’s you.
Investing through Revolut? You are legally responsible for the TOB. This obligation is yours, transaction by transaction.
If the burden falls on you, here’s what the law expects.
The TOB must be declared for each transaction via form 275, on MyMinfin, no later than the last business day of the second month following the transaction. Overlooked or forgotten, the obligation exposes you to very real penalties.
In other words, the bill can quickly exceed the tax itself. A declaration overlooked for several months, then caught up, is not a mere administrative detail: it’s a cost that accumulates, week after week.
And that’s not the only obligation. On a foreign platform like Revolut, the new capital-gains tax and the reporting of your foreign account also rest on your shoulders. To understand the whole framework and the exact status of the various platforms, the reference page Belgian stock-exchange tax (TOB) on foreign platforms covers everything, platform by platform.
The TOB is not a punitive tax in itself. The problem, with a platform like Revolut, is that it’s silent. Nothing in the app reminds you that a declaration is waiting, nothing computes the amount due, nothing alerts you as the deadline approaches.
And the more regularly you invest, the more tedious the tracking becomes: each transaction has its own date, its own amount, its own two-month deadline. Reconstructing all of this by hand, from exported statements, is exactly the kind of task you put off until tomorrow — until tomorrow costs €50 per week.
This is precisely the role Benchmarkr has set for itself: turning a diffuse obligation into clear, up-to-date information.
Bring your accounts together, Revolut included. Benchmarkr automatically computes the TOB due from your aggregated transactions and provides a periodic view of the taxes you owe. You no longer reconstruct anything by hand: you have, continuously, a clean read of what you owe and when it falls due.
The spirit is that of a high-end wealth assistant, not one more form. Benchmarkr is an assistance and computation tool: it brings clarity where the platform leaves little. It does not replace your declaration or personalized tax advice — it gives you the right figures, at the right time, to decide with peace of mind.
If you invest through Revolut or any other foreign app, the first useful reflex is to understand exactly what falls on you. The page Belgian stock-exchange tax (TOB) on foreign platforms lays out the rule, the deadlines and the status of the platforms — and lets you estimate your stock-exchange tax.
