· 🇧🇪 For: Belgian investors
ETFs come in two variants: distributing (they pay dividends into your account) and accumulating / capitalising (they automatically reinvest the income inside the fund). For Belgian investors, this makes a big tax difference.
The difference at a glance
| Distributing | Accumulating | |
|---|---|---|
| What happens to dividends? | Paid out into your account (typically quarterly or annually) | Automatically reinvested in the ETF |
| Dividend visible as cash flow? | Yes | No |
| Withholding tax (roerende voorheffing) | 30% on each dividend payment | Not immediately |
| TOB (stock-exchange tax) | 0.12% (wherever registered) | 0.12% (non-Belgium) or 1.32% (registered in Belgium) |
| Taxable moment | Each year a dividend is received | On sale |
The Belgian tax twist
In Belgium, accumulating ETFs have two specific advantages:
- No annual withholding tax — the income is reinvested inside the fund rather than paid out. No 30% withholding tax per year.
- Optimal compounding — you reinvest the full amount (no “tax leakage” via dividends).
But: accumulating ETFs that are registered in Belgium are subject to a higher TOB of 1.32% (instead of 0.12%).
Concrete examples:
- VWCE (Vanguard FTSE All-World Acc, registered in Belgium) → TOB 1.32%.
- IWDA (iShares Core MSCI World Acc, not registered in Belgium) → TOB 0.12%.
On a €1,000 purchase:
- VWCE: €13.20 TOB.
- IWDA: €1.20 TOB.
- On sale, the same TOB applies again.
Over a buy-and-sell cycle, the difference is 2.64% for VWCE versus 0.24% for IWDA. For long-term buy-and-hold, this is spread across the entire holding period.
Which variant suits whom?
Distributing makes sense for:
– Those who want to see regular cash flow in their account (for example in retirement, to cover expenses).
– Those who want to use the dividend exemption of €833 per person per year (2025 level) — although you have to actively reclaim this via your tax return.
Accumulating is generally more advantageous for:
– Long-term buy-and-hold investors in the accumulation phase (pre-retirement).
– Those who value automatic reinvestment and have no need for interim payouts.
Since 2026: the new capital gains tax
With the introduction of the 10% capital gains tax on 1 January 2026, the tax calculation has become more complex:
- On the sale of an accumulating ETF: 10% on the price gain above the annual exemption of €10,000.
- On distributing: same on the price gain (separate from the dividend withholding tax).
For most long-term buy-and-hold investors, accumulating generally remains more tax-efficient, but run the numbers explicitly for your own situation. See the pillar article Belgian investment taxes(NL) for the full calculation.
⚠️ Reynders tax on bond ETFs
The Reynders tax (art. 19bis WIB92/CIR92) levies 30% on the TIS component (the interest component plus debt-related capital gains) of funds with 10% or more bond exposure:
- Accumulating bond ETFs: always subject to the Reynders tax on sale.
- Distributing bond ETFs: exempt only if the fund rules explicitly require all net income to be distributed — a strict condition that only a small minority meet.
- VWCE and IWDA (the examples used in this article) are pure equity ETFs and therefore do not fall under the Reynders tax.
Since 1 January 2026 the Reynders tax (30% on TIS) and the new capital-gains tax (10% on the residual gain) exist side by side — they tax different components of the same sale and do not replace one another.
Additional note: above €1,000,000 average value on a securities account, the annual securities tax of 0.30% also applies — to accumulating and distributing ETFs alike. See the securities tax above €1 million.
Which variant should you actually pick?
The choice follows from two questions, in order.
- Do you need the income now? If so, distributing is more practical: you receive the payout without selling. It carries 30% withholding tax, but you avoid stock-exchange tax and a taxable gain on a sale.
- If not, compare stock-exchange tax per ISIN. An accumulating ETF on the FSMA list costs 1.32% per purchase; a distributing variant usually 0.12%. For monthly contributions that gap can consume the deferral advantage of accumulation entirely.
So the common rule of thumb that “accumulating is always better for tax” does not hold in Belgium. It held more strongly before 2026, when there was no capital-gains tax and deferral came closer to avoidance. Now it is a calculation per fund.
