In seinem Kommentar setzt sich Dieter Dziadkowski mit dem Vorschlag zum »Bayern-Tarif«, den Möglichkeiten zur Regionalisierung der Steuertarife und der kalten Progression auseinander.

In this paper we examine the degree to which Michigan's property value assessment growth cap has eroded the tax base and created substantial differences in effective tax rates among residential properties within the City of Detroit. While the analysis focuses on a specific city with significant...

In seinem Kommentar setzt sich Dieter Dziadkowski mit dem Vorschlag zum »Bayern-Tarif«, den Möglichkeiten zur Regionalisierung der Steuertarife und der kalten Progression auseinander.

After intensive and extensive preparation, the European Commission released the long-awaited proposal for a Council Directive on a Common Consolidated Corporate Tax Base (CCCTB) on March 16, 2011. In the context of the Europe 2020 Strategy, major objectives of the proposed CCCTB are the...

We use a unique matched tax return-financial statement data set to examine the magnitude and sources of book-tax differences in Germany. For the first time, the data set enables us to evaluate the extent to which financial and tax accounting differ in Germany in the most accurate manner. Despite...

Die Einheitswerte für Immobilien, auf die sich die Grundsteuer bezieht, wurden vom Bundesfinanzhof als verzerrend angesehen. Eine Arbeitsgruppe der Finanzminister beschäftigt sich schon seit Anfang 2010 mit diesem Problem. Dabei haben sich drei Modelle herauskristallisiert, die den Boden- und...

Imputed rental income of homeowners is tax exempt in most countries, despite the long-standing arguments recommending its inclusion in the tax base, on both equity and efficiency grounds. The current fiscal crisis revived interest towards this form of taxation. The paper investigates the fiscal...

This paper investigates the association between greater income inequality, de-facto fiscal space, and sovereign spreads. Using data from 50 countries in 2007, in 2009 and in 2011, we find that higher income inequality is associated with a lower tax base, lower de-facto fiscal space, and higher...

Die Komplexität des deutschen Steuersystems hat in den vergangenen Jahren immer wieder Kritik hervorgerufen und zu verschiedenen Verbesserungsvorschlägen geführt, von denen jedoch bislang noch keiner ungesetzt wurde. Denn um eine breite politische Akzeptanz zu erlangen, müssen...

In seiner Stellungnahme vom Dezember 2010 hat der Wissenschaftliche Beirat beim Bundesfinanzministerium vorgeschlagen, in die Bemessungsgrundlage für die Grundsteuer neben dem Bodenwert eine Gebäudekomponente einzubeziehen. Dirk Löhr hält den Vorschlag für verfehlt, weil er verschiedene...

We study the optimal combination of corporate tax rate and tax base in a model of a small open economy with heterogeneous firms. We show that it is optimal for the small country's government to effectively subsidize capital inputs by granting a tax allowance in excess of the true costs of...

The German corporate tax reform of 2008 has brought about important cuts in corporate tax rates, which were at the same time accompanied by significant changes in the determination of the tax base for both major German corporate taxes - corporate income tax and trade tax. The reform followed the...

The internationalisation of financial accounting and the European Commission's ambition to harmonise corporate taxation have raised the question whether IFRS accounts could be used for tax purposes. In order to quantify the effect of an IFRS-based taxation on corporate tax burdens in different...

Wie ist der von Paul Kirchhof in diesem Jahr vorgelegte Entwurf zur Reform des deutschen Steuerrechts zu beurteilen? Dieter Dziadkowski, Mitglied der Ursprungslandkommission und der Einkommensteuer-(Bareis)-Kommission, betont, dass der Reformentwurf »ein ganzheitliches Werk« sei mit dem Ziel,...

This note investigates the impact of greater income inequality on the tax base, on the defacto fiscal space, and the sovereign spreads. Using data from 50 countries in 2005 and in 2010, we find that higher income inequality is associated with a lower tax base, lower de-facto fiscal space, and...

This paper focuses on the legal monopoly for sporting bets in Germany. We analyze the pricing behavior of the monopolist ODDSET and find that typical pricing inefficiencies on betting markets are reinforced under the monopoly. This result in conjunction with the decreasing tax revenue may...

This paper analyzes tax competition when welfare maximizing jurisdictions levy source-based corporate taxes and multinational enterprises choose tax-efficient capital-to-debt ratios. Under separate accounting, multinationals shift debt from low-tax to high-tax countries. The Nash equilibrium of...

This paper studies corporate tax competition if it is costly to learn some of the elements that determine the effective tax burden. Search cost may, but need not, eliminate the tax competition pressure. The outcome depends on the boundaries of tax rate and tax base choices. Search cost can...

In 1994 a limit on the growth of property values for tax purposes was imposed in Michigan. One consequence of the newly imposed assessment growth cap was an emerging differential in tax prices between potential new property owners and long-time property owners. The purpose of this paper is to...

To what extent do countries' corporate income tax (CIT) rates attract foreign tax bases? What are the revenue implications of a unilateral tax reduction when tax bases are internationally mobile? These questions are explored using a panel of annual data from 17 OECD countries spanning the period...

This paper investigates the effect of fiscal equalization on the efficiency properties of corporate income tax rates chosen by symmetric countries in a Nash tax competition game under the taxation principles of Separate Accounting and Formula Apportionment. Fiscal equalization ensures efficiency...

This paper contributes to the discussion on Separate Accounting versus Formula Apportionment in the corporate income taxation of multinational enterprises (MNEs). The innovation of the analysis is that we consider a general equilibrium tax competition model with an endogenously determined world...

We estimate the elasticity of corporate taxable income with respect to the effective corporate tax rate on the basis of a pseudo-panel constructed from corporate tax return micro data for the period 1998-2001, a period which saw the introduction of a major corporate tax reform in Germany....

This paper investigates the choice of apportionment factors under a corporate tax system of Formula Apportionment. In contrast to perceived wisdom, we show that the apportionment formula contains both mobile (capital) and immobile (labor) factors if jurisdictions are granted full fiscal autonomy...

The EU Commission is advocating a common consolidated tax base for the corporate income tax, accompanied by a revenue sharing mechanism based on formula apportionment. We analyse tax competition in such a regime, focussing on the interaction between the definition of the tax base and the...

This paper analyzes the switch from Separate Accounting to Formula Apportionment in a dynamic framework. The model features both purely domestic corporations and a domestic multinational which invests at home and abroad as well as a purely foreign corporation and a foreign multinational which...

This paper focuses on firm valuation for tax purposes of non-listed company shares and its sensitivity towards different market conditions. Since the value of a private company cannot be observed on the stock market the value has to be estimated. Due to uncertainty, expected future profits may...

In diesem Beitrag werden die Effekte symmetrischer und differenzierender Besteuerung auf die Portfoliowahl und den Arbeitsanreiz untersucht. Hierbei wird zunächst ein Portfoliomodell mit zwei riskanten Projekten im Ein-Personen-Kontext, d.h. ohne Arbeitsanreizproblem betrachtet. Symmetrische...

Die Europäische Union schlägt vor, künftig auf die gesonderte Besteuerung der Gesellschaften einer multinationalen Unternehmung zu verzichten und stattdessen einen konsolidierten Konzerngewinn über einen Aufteilungsschlüssel auf die Ansässigkeitsstaaten zu verteilen. Damit sollen die im...

Der Beitrag setzt sich kritisch mit der Bewertung von Grundvermögen für steuerliche Zwecke auseinander. Um den Erhebungsaufwand der Finanzbehörden gering zu halten, werden einfache, auf wenigen Grundstücks- bzw. Gebäudemerkmalen basierende Bewertungsverfahren eingesetzt. Die...

We study how harmonization of corporate tax systems affects the stability of international cartels. We show that tax base harmonization reinforces collusive agreements, while harmonization of corporate tax rates may destabilize or stabilize cartels. We also find that bilateral and full...

This paper analyses the effects of introducing a common EU tax base with formula apportionment on the size of the EU wide tax base and on the distribution of the tax base between the EU member countries. We use a combined dataset of Deutsche Bundesbank's Foreign Direct Investment data (MiDi) and...

This paper evaluates the impact of globalization on the tax bases of countries at varying stages of development. We see globalization as a process that induces countries to embrace greater trade and financial integration, and macro stabilization. This in turn should shift their tax base from...

Presumptive taxation, in which an income proxy is used as tax base, has been and is still used today in countries with very diverse situations - developing, transition and developed countries. Usually, this form of taxation is thought of as a revenue-raising device in presence of widespread...

A theoretical analysis considers the impact of a typical system of redistributive ?fiscal equalization? transfers on the taxing effort of local jurisdictions. More specifically, it shows that the marginal contribution rate, i.e. the rate at which an increase in the tax base reduces those...

This article compares an ACE system with a CBIT system in an open economy. Using a realoption approach we show that, if a firm can decide when to invest, a tradeoff is found. According to traditional wisdom, a high-income firm investing in an ACE system faces a heavier tax burden at each...
