Wealth taxation vs. practical reality: navigating revenue mobilisation

As discussions around revenue mobilisation and fiscal reform intensify, the concept of reintroducing a wealth tax frequently surfaces as a potential panacea to boost state coffers. Proponents argue it could reshape the macroeconomic landscape, cure structural imbalances, and address wealth inequality.

However, before embracing this seemingly attractive fiscal tool, we must ask a critical question: why did Bangladesh abolish the Wealth Tax Act of 1963 in the first place, and why are nations globally abandoning it?

The original wealth tax was scrapped in 1999 not due to a single event, but because of insurmountable administrative friction and valuation complexities. The government astutely recognised that maintaining a complex, parallel assessment system for wealth valuation was highly inefficient.

In 2011, a more pragmatic approach was adopted: the Wealth Surcharge. This bypassed the need to independently value every asset at market rates, instead applying a straightforward percentage surcharge to the income tax of individuals whose net wealth exceeded specific thresholds. Hence, the surcharge is simply a tax on tax.

Despite this history, the theoretical allure of a pure wealth tax remains a subject of academic debate. From a public finance perspective, taxing accumulated wealth broadens the tax base, creating a fiscal framework less vulnerable to short-term economic downturns.

It attempts to capture the true economic power of high-net-worth individuals (HNWIs), who often fund their lifestyles by borrowing against the appreciation of their unrealized assets rather than drawing a taxable salary.

In theory, an effective wealth tax forces idle capital out of unproductive hoarding and into yield-generating investments, lowering the Gini coefficient and fostering a more meritocratic economy. It also incentivises the creation of a robust national database of asset ownership, severely curtailing tax evasion.

Contrary to the intention, replacing the current surcharge with a structurally capped wealth tax could recalibrate the burden—potentially reducing the overall tax liability for individuals who are both asset-rich and high-income, while ensuring that the wealth tax liability of an asset-rich, low-income earner remains practically tethered to their income tax capacity.

However, theoretical elegance often collides violently with practical reality. If we look beyond the textbook benefits, the reintroduction of a wealth tax in today’s Bangladesh presents severe structural and economic hazards. Assessing the fair value of illiquid assets invites endless valuation disputes. This increases compliance costs for taxpayers and collection costs for the National Board of Revenue.

More concerning is the current lack of interoperability among national asset registers. Until our data infrastructure is fully integrated, a wealth tax will inevitably become a penalty aimed squarely at the already compliant taxpayer, allowing those in the informal economy to slip through the cracks. Historical double ducks in the wealth tax legislation are the evidential tombstones worth mentioning here.

An ill-designed wealth tax regime may force major corporate sponsors, shareholders, and institutional investors to continuously liquidate equity positions. Sustained, forced sell-offs drain market liquidity, depress share prices, and severely hinder the overall capitalization of our stock exchanges, deeply unsettling the broader financial ecosystem.

Aggressive wealth taxation historically drives capital offshore through informal channels and trade misinvoicing. This capital flight does more than undermine domestic investment; it exacerbates pressures on foreign exchange reserves. At a time when the central bank is carefully optimising the crawling peg exchange rate and managing inflation, accelerating capital flight is a risk we cannot afford.

Individuals holding illiquid assets—such as an inherited family home in high-value zones like Gulshan or Dhanmondi, or shares in an early-stage private business—often lack the current cash flow to pay an annual tax based on theoretical market values. This forces distressed sales and disrupts long-term business planning.

Moreover, as our economy navigates the critical transition toward LDC graduation, domestic capital formation and industrial expansion are vital. Heavy taxation on accumulated capital disincentivises reinvestment in local industries, prompting capital to seek tax-friendly foreign jurisdictions and slowing down the manufacturing sector.

The international experience validates these concerns. During the 20th century, wealth taxes were widely adopted across Europe to promote equity. By 1990, around 12 OECD countries had them. Today, only a handful remain. The vast majority were abolished due to dismal revenue yields, exorbitant administrative costs, and severe economic distortions.

Modern tax systems are increasingly relying on broadening the income tax net, streamlining consumption taxes like VAT, and optimising property or inheritance taxes at the point of transfer, rather than levying direct annual taxes on static wealth.

Before attempting to resurrect a policy that failed us between 1963 and 1999, we must heed the lessons of our own fiscal history and global trends. The path to equitable revenue mobilisation lies not in penalising accumulated capital but in strengthening data interoperability, curbing evasion, and creating an environment where wealth is transparently reinvested in the real economy.
