How widespread is tax evasion – and what does that imply for the true extent of inequality? This research explores these questions by analyzing a unique dataset of leaked customer lists from offshore financial institutions matched to administrative wealth records in Scandinavia. The results show that offshore tax evasion is highly concentrated among the rich. The top 0.01% of households by wealth evade about a quarter of the taxes they owe, largely by concealing assets and investment income abroad. Top wealth shares in Denmark, Norway and Sweden increase substantially when adding back these unreported assets, highlighting the need to take account of tax evasion to measure inequality accurately.
There is considerable anecdotal evidence of US companies moving from high-tax states to low-tax states, but what do the data reveal about the impact of state taxation on economic activity? This research finds that firms subject to state-level corporate taxation respond to higher corporate tax rates by closing establishments and reducing employment; those subject only to state-level personal income taxation respond similarly to individual income tax rates, though to a lesser extent. Since half of these responses are due to reallocation of business activity to lower-tax states, tax competition across states clearly plays a first-order role in corporate decision-making.
In September 2008, the UK government announced a surprise stimulus policy in response to a dramatic fall in the housing market: a property transaction tax on houses sold in a certain price range was temporarily eliminated. This column reports research showing that this stimulus boosted transaction volumes by 20% and increased consumer spending by an amount equal to the forgone tax revenue. Cutting transaction taxes during economic downturns can thus be an effective way to stimulate both the housing market and the broader economy.
Quantifying who benefits from corporate tax cuts requires estimates of the effects of taxes on the local economy and on the location decisions of firms and workers. This research analyses every change in state business taxes in the United States since 1980 to show that the largest beneficiaries from a tax cut are the owners of firms (40%), with landowners and workers splitting the remaining (60%) of the economic gains. Where the benefits of corporate tax cuts fall ultimately depends on the relative mobility of firms and workers – and many factors other than tax rates influence their choice of location.
This paper shows that taxes affect the international location decisions of the best “superstar” inventors. Higher tax rates lead to a significantly lower share of superstar inventors remaining in their home country and a lower share of foreign superstar inventors who move to the country. This may have significant fiscal and innovation costs for a country that should be taken into account when setting tax policy.
Tax collectors in developing countries collect far less tax revenue as a share of gross domestic product than tax collectors in higher income countries. In many of these developing countries, tax officials have discretion in assessing, enforcing, and auditing taxes. In addition, they earn relatively low wages with fewer rewards for good performance, allowing for the possibility of collusion with taxpayers. In the case of property taxes, officials may accept payments in exchange for leaving properties off the tax rolls, granting inappropriate exemptions, or assessing properties at a lower rate, all of which lead to lower revenues for the state.
