ETF tax in Belgium — TOB, Reynders and no capital gains tax

The stock exchange tax is charged on each side of a round trip — once when you buy and once when you sell. The rate is 1.32% for a fund that is both registered for public distribution in Belgium and accumulating, and 0.12% for everything else. That is a 11-fold difference decided entirely by the share class, and it dwarfs any plausible difference in ongoing charges between two funds tracking the same index.

Each side is capped: €4,000 at the high rate and €1,300 at the low one. Above about €303,030 per trade the high rate stops being a percentage and becomes a flat fee, which narrows the gap between the two brackets considerably — so the headline 11-fold figure applies to ordinary trade sizes rather than to large ones.

Brokers differ on how they determine registration, and some apply the high rate to every accumulating Irish ETF as policy. The rate on your own order confirmation is the one that counts, and it is worth checking against the rate you assumed.

Because the charge is a one-off rather than a recurring one, its annual cost depends entirely on how long you hold. The same round trip costs the same euros whether it spans one year or thirty — but spread across thirty years the annual equivalent is a thirtieth of what it is across one.

This makes Belgium the country where frequent rebalancing is most expensive and long holding is most rewarded, and it inverts the usual advice about the two. It also means comparing the transaction tax against a fund's ongoing charge requires converting one into the other: a charge paid twice over a long holding is a very different thing from one paid every year.

Belgium taxes the bond portion of a fund's return at 30% when the fund holds more than 10% in bonds. A pure equity tracker escapes it entirely; a fund a single percentage point over the line does not, which makes the threshold worth checking rather than estimating.

The levy applies to the interest component of the gain when you sell, and it exists because Belgium taxes interest income generally — so a fund holding bonds should not be a way of converting taxable interest into untaxed capital gain. It is the exception that proves how unusual the no-capital-gains rule is.

There is no annual wealth tax on a securities portfolio of ordinary size, and no capital gains tax on the equity portion when you sell. Compared with a Dutch investor paying every year regardless of performance, or an Italian one paying stamp duty on the balance annually, a Belgian equity investor holding a registered distributing fund for a long period pays remarkably little.

The corollary is that the decisions worth getting right are concentrated at the point of purchase: the share class, the registration status and the bond weighting are all fixed before you own the thing, and none of them can be optimised afterwards without paying the transaction tax again.

Is there really no capital gains tax on ETFs in Belgium?

Not on the equity portion, for an ordinary private investor managing their own wealth. The bond portion is caught by the Reynders levy at 30% above a 10% bond holding, and trading frequently enough to look like a professional activity is treated differently. For a long-term equity holder the absence is real.

Should I pick a distributing fund to get the lower transaction rate?

It is the single cheapest decision available, since the low rate applies to distributing funds regardless of registration. Weigh it against the dividend withholding tax you will then pay on each distribution, and against the commission on reinvesting them — for a frequent trader the transaction saving dominates, and for a long-term holder making few trades it may not.

Does the cap ever work in my favour?

Above roughly €303,030 per side at the high rate, yes. Past that point the charge is fixed, so a larger trade costs proportionally less and the gap between the two rate brackets narrows. It is one of the few places where a larger transaction is cheaper per euro, and it makes consolidating several planned purchases into one worth considering.
