Box 3 2028 Changes Cancelled

Thanks to Staden Financial Management for providing us with this article

Christmas came early for Dutch investors this week, as the cabinet officially pulled the plug on its disastrous 2028 Box 3 tax overhaul. According to leaked budget documents ahead of Prinsjesdag, the plan is dead in the water. Good riddance. For a while there, it looked like the Netherlands was going to pioneer a masterclass in economic self-sabotage.

“Capital Growth Tax”

At the heart of this abandoned legislation was the frankly absurd “capital growth tax,” a mechanism designed to tax unrealized paper gains every single year. I’ve written extensively before about why this was a ticking time bomb for the Dutch economy, but the core issue was always liquidity.

The reality of taxing phantom profits is that it forces a cash crisis on ordinary investors. If your stock portfolio or rental property goes up in value on paper, but you haven’t sold it, you still owe the taxman cold, hard cash. Under the now-scrapped plan, people would have been routinely forced to liquidate assets just to cover their annual tax bills. While the government originally pitched this as a silver bullet to prevent perpetual tax deferral by the ultra-wealthy, the collateral damage to everyday investors would have been catastrophic.

But the government isn’t completely off the hook. They remain legally cornered by the 2021 Supreme Court ruling, which rightfully declared that taxing fictional returns is unlawful. The state will eventually have to tax actual returns. Now that this unworkable proposal is parked, policymakers are back to square one and desperately need a system that won’t get laughed out of the Senate.

So, How Should the Market React?

With a massive sigh of relief. By scrapping the annual paper-gains tax, the cabinet is essentially admitting defeat and signalling a necessary pivot toward a traditional, realized capital gains tax. This is how the rest of the sane financial world operates: you make a profit, you sell the asset, you pay the tax.

To be fair, a realized system creates its own headaches for the treasury—namely the “lock-in effect,” where investors simply refuse to sell assets in order to avoid triggering a tax event. Dutch policymakers have historically hated this because it makes tax revenues unpredictable and can stagnate capital flow. But frankly, that is a treasury problem, not an investor problem. A realized tax is fundamentally fairer, directly linking the tax burden to the actual cash in an investor’s pocket.

As for what happens next, I wouldn’t hold my breath for a 2028 rollout. Designing a bulletproof realized tax system from scratch takes years, and Dutch politics is not known for its speed or for its ability to create a bulletproof tax system. Until a functional alternative is drafted, the current temporary bridging legislation will stick around, with all its poorly thought-out consequences. As they say, nothing is so permanent as a temporary government fix. But for now, investors can sleep soundly knowing they’ve avoided the worst-case scenario.
