Is there a viable way to tax large fortunes? Is it beneficial for the economy?

Over the past four decades, the total accumulated wealth in developed countries has risen to more than six times national income, up from around three times previously. At the same time, the distribution of wealth has become highly unequal. Nevertheless, most countries still do not impose a general and direct wealth tax, even though such a tax could help address the increasingly difficult task of financing the public sector worldwide.

Is there a viable way to tax large fortunes? Is it beneficial for the economy?

Current tax systems primarily burden labour income, while the wealthiest individuals can easily minimise taxation by not selling their assets, thereby avoiding income tax. A precisely targeted wealth tax could generate substantial revenue from a narrow, affluent segment of society. It could also encourage owners to shift their wealth into investments promising higher productivity and returns, rather than holding it in underutilised assets. However, introducing a wealth tax is far from straightforward and may have adverse effects—for example, it could lead to mobile wealth fleeing to countries where it is not taxed.

Arguments against introducing a wealth tax


  • It can be difficult and costly to administer: accurately valuing certain assets—such as privately held businesses, agricultural land, or artworks—can be challenging.
  • Therefore, it may generate less revenue than expected.
  • Wealth may be valuable while the owner lacks liquid resources—for example, valuable real estate but no cash.
  • It may lead to capital flight.
  • The system may become overly complex: rules introduced in the interests of fairness may be abused and serve as legal loopholes. This increases the costs of maintaining and monitoring the system and may consume the tax revenue collected.

What makes a wealth tax viable and beneficial?


Despite the difficulties outlined above, there are also examples where a wealth tax works well in practice, such as in Switzerland and Norway.

Target only very large fortunes: a high exemption threshold

The regulation should indeed target only the wealthiest individuals—the super-rich—rather than the broader population of well-off citizens.

Keep the tax rate low

Even a tax rate of 1% is considered high by international standards.

Broad tax base: all types of wealth

It is advisable to include all categories of wealth in the tax base so that the tax cannot be avoided through exemptions.

Exemptions should encourage reinvestment but not be exploitable

Any exemptions should promote the domestic reinvestment of wealth to stimulate the Hungarian economy and increase employment, while not allowing opportunities for tax avoidance.


A wealth tax integrated into the overall tax system


A wealth tax should be integrated into the overall tax system and should not create opportunities for tax avoidance or the transfer of wealth. The revenue from the wealth tax could be used to reduce taxes that currently burden labour or capital income.

Preventing capital outflows abroad

It is important that the regulation does not incentivise wealthy individuals to move abroad or withdraw their investments.

Ensure social fairness

The tax should contribute to a fairer distribution of the tax burden and should not create new social tensions.

Although introducing a wealth tax poses both political and technical challenges, a well-designed system can be an effective tool for reducing widening wealth inequality and stabilising modern economies.

How can a wealth tax encourage more efficient investment?

A wealth tax promotes more productive use of capital through several mechanisms:

Tax liability independent of returns

A wealth tax is payable regardless of the actual income generated by assets. Owners must pay tax even if, for example, a vacant property or a loss-making stock generates no profit. Therefore, it makes little sense to hold capital in assets that generate little or no return, not even enough to cover the tax. This would encourage owners to direct their money towards more efficient and profitable investments.

Replacement of other capital taxes

In principle, a wealth tax could allow less efficient capital taxes to be reduced or eliminated, thereby improving the efficiency of investment decisions.

Reducing taxes on labour

Revenue from a wealth tax could reduce the tax burden on labour, potentially increasing overall economic dynamism.

A well-designed wealth tax can therefore help ensure that capital does not remain tied up in underutilised assets but instead plays an active role in value creation and economic growth.
