We analyze bunching of closely held corporations at the 200,000 euros kink in the Dutch corporate income tax schedule. To do so, we use tax return and administrative data linking firms to their owners over 2009-2018. We find an overall elasticity of 0.07, which is mainly driven by responses built within the tax return. We investigate heterogeneity in individuals' and firms' characteristics and the use of targeted tax incentives. We find greater tax responsiveness for large firms using deductions for energy and environment investments and operating in energy and agriculture, forestry, and fishing industries. We show persistence in bunching, which is driven by large firms using deductions repeatedly and by firms owned by director-owners who locate repeatedly near personal taxable income kinks.

Changes to loss offset rules are often used as a fiscal stimulus measure in times of crisis to alleviate firms' constraints and support the economy. The effect of these measures has been assessed in the literature using large listed firms, but there is no evidence on the effect of these policies on small private firms so far. We study a temporary change in the loss carry-back period implemented in the Netherlands over 2009-2011 using administrative and tax return data on small private corporations. Using a difference-in-difference set up and matching techniques, we show that an additional year of carry-back has a significant effect on treated firms' investments, but no significant effect on firms' survival, employment and profits. The positive effect on investments is not driven by equity injections but rather by debt increases. Crucially, the significance of the effect on investments is conditional on the size of the additional carry-back.

We study how differential taxation of personal and corporate income impacts the corporate share of new firms for 31 countries over 1998-2018. We build a novel database that identifies the tax treatment of partnerships either as corporations or pass-through entities. We find a tax elasticity of 0.07 for the period 1998-2007 and of 0.12 for 2008-2018. Estimates are larger for countries where the presence of partnerships is non-negligible and where they are treated as pass-through for tax purposes, suggesting that the tax sensitivity of organizational form choice interacts with the relevance of partnerships and their tax treatment.

We study the effect of the reduction in the VAT rate on hairdresser services from 17.5 to 6% in the Netherlands in January 2000. Following Kosonen (J Public Econ 131:87–100, 2015), we use differences-in-differences to estimate the effects of this reform, with beauty salons as the main control group. In our preferred specification, we find close to full pass-through of the VAT cut into lower prices. However, we find no statistically or economically significant effect on the volume of sales or employment.
