Voka Growth Account Plan Aims to Unlock €185 Billion

Flemish employers’ organization Voka has proposed a new “growth account” (groeirekening) designed to unlock approximately €185 billion in idle household savings, drawing inspiration from Sweden’s successful Investeringssparkonto (ISK) model. The plan, presented to Belgian Finance Minister Jan Jambon on June 8, would replace Belgium’s complex web of investment taxes with a single, low flat tax on account value — explicitly avoiding new capital gains or stock market transaction taxes, according to Het Laatste Nieuws.

The Belgian Savings Paradox

Belgian households currently hold over €300 billion in regulated savings accounts, many earning near-zero interest. A report from VRT News noted that as of December 2024, €277.6 billion sat in savings accounts alone — the highest figure since the government’s bond issue raided €22 billion from accounts in 2023. This cultural preference for security, reinforced by generous tax advantages on the first €1,020 in savings interest, has created what economists call the “Belgian savings paradox”: abundant capital that generates minimal returns for households and provides little fuel for the real economy.

“Belgium needs €29 to €35 billion in additional annual investments to green, digitalize, and strengthen its economy,” said Frank Beckx, CEO of Voka, as reported by HLN. “The money is there, but Belgians are still too afraid to invest.”

How the Growth Account Would Work

Modeled on Sweden’s ISK, introduced in 2012, the growth account would offer a radically simplified investment framework. Instead of taxing realized capital gains, dividends, or transactions — Belgium currently levies the 30% withholding tax on dividends, the beurstaks (stock market transaction tax), the Reynderstaks, the annual securities tax on accounts above €1 million, and the newly introduced meerwaardebelasting (capital gains tax) — the growth account would impose a single annual flat tax on the total account value.

“The account must be digital and quick to open, without minimum deposit,” Beckx explained. “And above all: not thirty-one different taxes, but one uniform, transparent flat tax.”

Key features include no minimum holding period, no penalties for early withdrawal, no cap on investment amounts, and fully automated tax handling — mirroring the Swedish system that has seen 41% of Swedes over 15 open an ISK account, representing 29% of GDP in invested capital. For 2026, Sweden’s ISK flat tax rate stands at approximately 1.065%, with amounts up to €27,600 (300,000 SEK) entirely tax-free, as detailed by The Local Sweden.

Economic Impact and Expert Reaction

Voka estimates that if Belgium matches Sweden’s adoption rate, approximately €185 billion — equivalent to 29% of Belgian GDP — could flow into investment markets. Currently, only 15% of Belgian financial wealth is invested in the stock market; Voka believes this could double.

Pascal Paepen, financial expert at HLN, welcomed the proposal. “Bring it on, this is certainly a good proposal. Such a simple and fiscally interesting model could certainly work,” he said. However, Paepen noted a key legal constraint: “It is not possible to make a fiscal distinction between Belgian and European securities. The model will therefore have to apply at least to all shares of companies across the entire European Union.”

Beckx acknowledged this limitation but expressed optimism that Belgians would naturally favor domestic investments. “Our economy benefits most from investment in Belgian stocks, funds, and ETFs, but we cannot legally enforce that. We count on the home market advantage: people invest more readily in what they know.”

Tax Revenue and Political Context

The proposal arrives at a politically sensitive moment. Belgium’s Arizona coalition government introduced a capital gains tax (meerwaardebelasting) in January 2026 as part of its budget agreement — a controversial measure that Voka’s growth account would effectively circumvent for account holders. Yet the coalition agreement also explicitly states the ambition to “activate Belgian savings,” giving Voka political leverage.

Paepen argues the flat tax would likely increase overall tax revenue. “On the many billions in savings sitting in our savings accounts, the state currently collects virtually zero taxes,” he noted. Voka’s broader policy priorities, outlined on its official website, include strengthening the European Capital Markets Union and making the Brussels stock exchange more attractive — goals the growth account directly serves.

Challenges Ahead

Despite the proposal’s ambition, significant hurdles remain. The flat tax rate for a Belgian growth account has not been specified, and no legislative timeline exists. Public skepticism is evident in reader comments on the HLN article, with concerns about changing rules and hidden risks. Banks, according to Voka, are prepared to offer the account, but no financial institution has publicly confirmed this.

Moreover, EU legal constraints mean the tax advantage would apply to all EU-listed securities, potentially diluting the domestic economic impact. The transition from Belgium’s current multi-tax system to a single flat tax would require significant legislative coordination.

What to Watch For

Finance Minister Jan Jambon has received the proposal, but no official government response has been reported. Voka hopes the minister will work on it in the coming months. The coming weeks will reveal whether the Arizona coalition — already navigating budget constraints and the political fallout from the capital gains tax — sees the growth account as a complementary reform or a competing vision for Belgium’s investment landscape.

For Belgian households sitting on billions in near-zero-interest savings, the question is whether a Swedish-style model can overcome deep-rooted risk aversion — and whether the government can resist the temptation to change the rules once the money starts flowing.
