Does Taxing The Wealthy Actually Hurt The Economy?
This study evaluates whether taxing top wealth triggers a mass exodus of wealthy business owners and quantifies the actual "trickle-down" damage that their international departure inflicts on the broader economy.
Takeaway: While wealth taxes induce a small fraction of rich entrepreneurs to move abroad and hurt the specific businesses they leave behind, the overall fallout on national employment and economic growth is surprisingly small.
Key Points
A 1 percentage point increase in the top wealth tax rate reduces the long-term population of wealthy taxpayers by roughly 2 percent through increased move-outs and reduced move-ins.
When a wealthy owner emigrates, their individual business experiences a 33 percent drop in employment, but roughly 45 percent of these disrupted businesses are reabsorbed by other domestic firms through mergers.
Across the whole economy, the net economic drag of tax-driven migration is modest: a 1 percentage point wealth tax increase reduces aggregate national employment by 0.02 percent and aggregate investment by 0.07 percent.
When governments consider taxing top wealth to reduce inequality, critics immediately raise two fears: First, the super-rich will simply pack their bags and move to lower-tax jurisdictions. Second, because many wealthy individuals are entrepreneurs, their departure will kill jobs, stifle innovation, and destroy local businesses.
These concerns sit at the heart of debates over how to fund public services and fix rising inequality. If billionaire departures drag down the whole economy, a wealth tax could end up costing society far more than it brings in. But despite how prominent this argument is, real-world evidence measuring the actual economic spillover of tax-driven migration has long been scarce.
What Did the Researchers Study?
The authors set out to answer two fundamental questions: How sensitive are the rich to wealth taxes when deciding where to live, and how much does their departure actually hurt the domestic economy?
To find out, the researchers analyzed decades of exhaustive administrative data from Sweden and Denmark. These detailed registries tracked total wealth, business ownership (including subsidiaries held through holding companies), and precise international moves. The team measured how migration responded to major wealth tax reforms—such as Sweden’s complete repeal of its wealth tax in 2007—and tracked the multi-year health of the businesses those migrants left behind.
Findings
The researchers found clear evidence that rich taxpayers respond to wealth taxes by moving. In Sweden, repealing the wealth tax reduced the rate at which top wealth holders moved abroad by about 30 percent. However, because international moves are rare to begin with—fewer than 1 in 300 wealthy individuals move abroad in a given year—these tax responses translate into a modest long-term impact. The authors estimate that a 1 percentage point increase in the top wealth tax rate decreases the steady-state stock of wealthy taxpayers by just 2 percent.
At the individual business level, an owner’s departure can be disruptive. When a wealthy entrepreneur leaves the country, employment in their directly owned firm falls by 33 percent, value added drops by 34 percent, and investment drops by 22 percent over five years.
Crucially, however, the study reveals that economy-wide "trickle-down" damage is heavily muted by economic reallocation. Nearly half (45 percent) of the firm closures triggered by an owner’s departure are absorbed by other domestic businesses via mergers and acquisitions. Furthermore, workers displaced from those firms experience only minor, short-lived wage losses before finding new jobs.
Combining these factors, the aggregate economic impact on the entire nation is remarkably small. A 1 percentage point increase in the top wealth tax rate decreases national employment by 0.02 percent, overall investment by 0.07 percent, and total economic output (value added) by 0.10 percent.
From a government budget perspective, for every $1.00 raised directly by a wealth tax, about $0.22 is lost because people move away (losing income and corporate tax revenues as well as wealth taxes). By contrast, direct tax avoidance and reduced savings among stayers cause a much larger revenue loss of $0.54 per dollar raised.
Limitations and Context
These findings come from Scandinavian countries, which are small, open economies. Highly mobile citizens within the European Union face few legal hurdles to moving across borders. In larger economies like the United States, strong business clusters and geographical advantages might make top entrepreneurs even less likely to leave, meaning these estimates likely represent an upper bound on migration risks.
Why It Matters
This research injects grounded empirical facts into a polarized policy debate. It shows that while tax-driven migration is real and does harm specific firms, fears of a catastrophic economic collapse or massive job losses are overstated. For policymakers, the key bottleneck of a wealth tax isn't the threat of people moving away—it is managing domestic tax evasion and avoidance among those who stay.

Economic Concept: Fiscal Externalities
A fiscal externality occurs when a change in one tax policy causes people to alter their behavior in ways that unintentionally affect revenue collected from other taxes.
For example, if a government introduces a wealth tax, a wealthy entrepreneur might decide to move to another country. While the government loses out on the expected wealth tax, the real fiscal damage comes from the loss of the income taxes, sales taxes, and corporate tax revenues that the entrepreneur and their business used to generate locally. Accounting for these broader spillover losses helps governments measure the true net revenue a tax reform will deliver.
