The purpose of this paper is to investigate the relationship between book‐tax differences and earnings quality for commercial banks in Taiwan. The paper focuses on the banking industry because industry‐specific accrual models of accounting discretion in the loan loss provisions are available to develop powerful tests of earnings management related to book‐tax differences. In addition, the paper replicates the analysis of book‐tax differences that previous studies conducted on a heterogeneous sample of nonfinancial firms, to ascertain whether prior inferences also hold in the study's sample of banks in an emerging economy.

This paper estimates the magnitude of discretionary loan loss provisions as a proxy for earnings quality (positively correlated with earnings management; therefore, inversely correlated with earnings quality). Then, the study partitions the sample into three subsamples (large positive book‐tax differences, large negative book‐tax differences, and small book‐tax differences) to set the regression models.

This paper finds that bank‐years with large positive or negative temporary book‐tax differences have discretionary loan loss provisions that are greater than bank‐years with small temporary book‐tax differences. The paper also finds that bank‐years with large temporary book‐tax differences have one‐year‐ahead persistence of current earnings and accruals that are less than those with small temporary book‐tax differences. Additionally, the study does not find a significant relation between permanent book‐tax differences and earnings quality. Overall, the evidence is consistent with the supposition that large temporary book‐tax differences are associated with lower earnings quality.

The study contributes to the literature on book‐tax differences and earnings quality in two ways. First, the paper provides evidence to ascertain prior inferences that the association between book‐tax differences and earnings quality also hold in the banking industry, it may generalize to the banking sector in other emerging countries. Second, the study utilizes a banking‐specific accrual model to construct more powerful tests of information in book‐tax differences for earnings quality. The study has an inherent limitation arising from small sample size of the banking industry in an emerging economy. Future tax accounting researchers should develop appropriate country‐specific measures of book‐tax differences.

The purpose of this paper is to investigate the direct and indirect links between book-tax differences (BTDs) and audit quality using accounting conservatism (proxy of earnings quality). Hence, this paper seeks to extend prior audit quality research.

This study uses a sample of Tunisian listed firms on the Tunis Stock Exchange and operating in the industrial and commercial sectors during 2005-2012. This investigation is motivated by structural equations system models that specify both a direct link and an indirect link that is mediated by information reflected in BTDs.

The results show that for the Tunisians companies, firms with large BTDs are associated with higher audit quality implies that such BTDs represent an observable proxy for earnings quality that affects auditor decisions. The authors find statistically an indirect link between abnormal BTDs and audit quality that is mediated by earnings quality. The current study also provides evidence that information reflected in BTDs can improve audit quality.

The findings may be of interest to the academic researchers, practitioners and regulators who are interested in discovering the informational value of BTDs in the audit process.

This paper extends the existing literature by examining the mediation effect of information reflected in BTDs on relationship between BTDs and audit quality.

The purpose of this paper is to investigate the effect of financial factors on firms’ financial and tax reporting decisions. Firms often face the difficulties of accomplishing both financial and reporting goals. The extent to which reporting they put more value depends on the differential weighting of firms’ financial reporting and tax costs. The authors incorporate various financial factors as a source of cross-sectional differences in the weighing of both financial reporting and tax costs.

To examine firms’ decisions when fulfilling both the purposes of financial and tax reporting is difficult, the authors use a large set of firms in Korea, where book-tax conformity is high and aggressive tax shelters are restricted. The authors develop a new measure that can specify firms’ decision making between financial and tax reporting by considering both earnings management and tax avoidance.

The findings show that debt ratio affects firms’ financial and tax reporting decisions non-monotonically depending on the level of the debt ratio. The authors also find that firms with more long-term debt financing are more likely to be aggressive in financial reporting, while firms with higher financing deficit or better access to the capital market are more likely to be aggressive in tax reporting.

Thus, the findings provide more compelling evidence of firms’ decision making between two conflicting strategies, particularly when fulfilling both the purposes of financial and tax reporting is difficult. The authors expect that the results provide practical implications to standard setters, auditors and financial statement users who are interested in the ongoing debate over book-tax tradeoffs.

This paper fulfills an identified need to study how firms’ decision making between two conflicting reporting strategies are affected by the various financial factors, which are closely linked to a firm’s financial reporting and tax costs.

The purpose of this paper is to empirically explore whether and to what extent the changes in state corporate income tax rates affect corporate tax aggressiveness.

Using a differences-in-differences approach with dynamic treatment, the authors investigate the effect of staggered changes in state corporate income tax rates in the USA on corporate tax aggressiveness.

Firms become more aggressive in avoiding taxes following state tax increases but are insensitive to tax cuts. The effect of state tax increases on tax aggressiveness is weaker for firms with greater debt tax shields and marginal tax rates. Firms are more likely to shift their operations and relocate their headquarters out of states experiencing tax increases.

To the best of the authors' knowledge, this paper is the first to study the relation between state tax policy changes and corporate tax aggressiveness. This paper finds an asymmetrical pattern of corporate tax aggressiveness in response to state tax changes.

The purpose of this paper is to examine the effect of financial derivatives usage and country’s tax environment characteristics on the relationship between financial derivatives and tax avoidance.

This study uses a cross-country analysis with the scope of ASEAN (Association of Southeast Asian Nations) countries which consists of the Philippines, Indonesia, Malaysia, and Singapore.

The level of financial derivatives usage positively affects the level of tax avoidance. This finding indicates that financial derivatives can be used as tax avoidance tool. Furthermore, the positive effect of the level of financial derivatives usage on the level of tax avoidance is lower in countries with a competitive tax environment than in countries with an uncompetitive tax environment. This finding indicates that in country with a competitive tax environment, the use of financial derivatives as a tax avoidance tool can be replaced by the tax facilities provided by that country.

This study uses four countries in the Association of Southeast Asian Nations region and does not test the sample based on the financial derivative types.

Tax authorities need to establish a clear tax regulation in regard to the tax treatment of financial derivatives transactions, e.g. define the definition of financial derivatives for hedging purposes and financial derivatives for speculative purposes; and define specific criteria to separate financial derivatives for hedging purposes from financial derivatives for speculative purposes. It is necessary to determine whether losses arising from derivative transactions are classified as deductible expenses or non-deductible expenses.

To the best of the authors’ knowledge, this study is also the first that provide empirical evidence that the relationship between financial derivatives and tax avoidance activities depends on a country’s tax environment.

This paper develops novel proxies for labour tax avoidance (LTAV) and tests their validity within a sample of 189 labour tax-avoidant offending firms (LTAOFs) accused of evading social security contributions (SOCs) by public authorities.

LTAV proxies are based on abnormal values of SOCs paid, reported in the income statements of a sample of 857,790 Spanish firm-years for the period 2001–2015, estimated through two-stage least square panel data regressions with firm fixed effects.

The results reveal that proxies specifically built to signal both conforming and non-conforming LTAV can provide evidence of abnormally low SOCs as expenses within the sample of LTAOFs. Furthermore, firm-specific financial variables as well as macroeconomic variables significantly influence LTAV.

This study could foster further research on the efficacy of the LTAV proxies and on the drivers and sustainability implications of LTAV for firms and their stakeholders in different socio-economic and institutional contexts.

These LTAV proxies could integrate other methods applied to estimate the undeclared work and its trends. Furthermore, they may assist tax authorities to direct their inspections, detect labour tax evasion and then strengthen the social protection of the employees from employers' illegal exploitation practices, as well as reducing tax revenue shortfalls and related sustainability concerns in the social security systems.

This study proposes a novel methodology to examine LTAV and its determinants through accounting information. This methodology may support researchers to provide a more comprehensive picture of tax planning strategies pursued by companies, that include LTAV, and in this way integrate the extant mature literature on income tax avoidance.

The purpose of this paper is to investigate the effect of ownership structure arising from China’s unique privatization process on listed firms’ tunneling activities and their interaction with tax avoidance.

Using hand-collected data on the incompletely restructured state-owned listed firms and their applicable tax rate, this paper conducts a multivariate regression to test research questions. It also employs a triple differences method to examine whether the observed interaction between tax avoidance and tunneling is mitigated for well-governed firms.

It documents that controlling shareholders’ tunneling increases as the percentage of shares owned by state-owned enterprises (SOEs) increases. Evidence also shows that the magnitude of tunneling increases when SOEs controlled by the central government engage in more tax avoidance, suggesting that these firms use tax avoidance to facilitate wealth expropriation.

These findings advance the understanding of the tunneling incentive behind the tax avoidance behavior for a subset of Chinese SOEs and have implications for emerging capital markets that are characterized by concentrated government ownership and weak corporate governance.

This paper is the first paper to investigate the effect of the incomplete privatization process on tunneling and the interaction between tunneling and tax avoidance activities. It extends prior studies by investigating the incentives behind SOEs’ tax avoidance from the perspective of an agency problem and documenting that good corporate governance plays an important role in deterring the diversionary tax avoidance.

This study aims to examine the contingent fit between business strategies and environmental uncertainty and its effect on corporate tax avoidance.

This study uses a two-stage linear regression method comprising multinomial logistic regression and panel data regression.

This study finds that under highly uncertain conditions, the contingent fit of prospector strategy is higher than the contingent fit of other two strategies, i.e. defender and analyzer strategy. The study fails, however, to demonstrate that under highly uncertain conditions, this study finds that under highly uncertain conditions the contingent fit of a “prospector” strategy is higher than for “defender” and “analyzer” strategies. The study fails, however, to demonstrate that under highly uncertain conditions the contingent fit of a defender strategy is higher than that of an analyzer strategy. The study also finds that the contingent fit between prospector strategy and environmental uncertainty has a positive effect on tax avoidance, and this effect is higher than for the misfit strategies. Moreover, in such environments the fit level of a defender strategy has a negative effect on tax avoidance while environmental uncertainty has a positive effect on tax avoidance.

This study estimated competition uncertainty using the Herfindahl index to measure competitive intensity in an industry. However, only the data from public listed companies was used due to a lack of data availability for non-public companies. Consequently, further study is recommended to include the total number of companies within an industry as a proxy of competitive intensity.

The results implied that managers, not only in Indonesia but also in other countries as well, specifically emerging countries (generally the environmental uncertainty in emerging countries is high) should consider the contingent factors when making business strategy decisions. Managers must be aware of the contingent fit with environmental uncertainty, and therefore, must assess external conditions prudently. Furthermore, the results of this study showed that managers should pay more attention to the effects of their decisions on corporate tax avoidance, while aligning their business strategy decisions with corporate tax planning strategy to obtain an optimal outcome for the company.

The Directorate General of Taxes and Board of Fiscal Policy, as regulators, need to comprehend environmental uncertainty to issue various policies that can ease the burden of the taxpayer to remain in business, particularly during the turbulence environment so that can prevent the companies doing illegal practices and will eventually reduce the number of tax avoidance.

This study developed alternative measure of tax avoidance, which is tax avoidance latent variable score (TAXLVS). The TAXLVS was derived from confirmatory factor analysis of previous existing tax avoidance measurements. This study is also the first that analyzes the effect of business strategy on tax avoidance using contingency approach.

This paper aims to examine the effect of contractual factors and noncontractual factors on tax avoidance (TA).

The sample comprises 400 firm-year observations of 67 companies listed on the HDAX during the period 2008–2017. The generalized least square panel regression is applied.

The study results confirm a significant effect of long-term chief executive officer (CEO) compensation incentives and CEO attributes on TA. Findings exhibit a significant impact of foreign CEO on TA, whereas an insider CEO mitigates TA. The results hold for several robustness tests, with lag effective tax rate as dependent variable and with splitting foreign CEO into European and non-European origin.

First, the sample is limited to 400 firm-year observations and to the German context. For shareholders, the study provides first evidence on relationships between the geographical and internal versus external labor market for CEOs and TA. For researchers, the findings underline the importance of integrating behavioral approaches like place attachment theory and the rooting theory in the theory of TA.

To the best of the authors’ knowledge, this is the first study to examine the impact of both contractual determinants and behavioral determinants on TA in the German context as an emerged economy with a dualistic corporate governance. This study contributes to the existing literature regarding the scientific debates about the impact of CEOs and CEO attributes on TA. It also analyses the balance between the place attachment theory and the rooting theory in the face of the compensation outcomes of agency theory.

The purpose of this study is to examine the moderating effect of sustainability reporting on the relationship between tax avoidance and firm value. This study also examines the moderating effect of sustainability reporting in both environmentally sensitive firms and non-environmentally sensitive firms.

This research uses moderated panel regression with 596 observations and 734 observations for cash effective tax rate (ETR) and generally accepted accounting principles effective tax rate (GAAP ETR) of firms listed on the Indonesian Stock Exchange between 2014 and 2016. Tax avoidance is measured by both cash ETR and GAAP ETR.

This paper shows that sustainability reporting moderates the relationship between tax avoidance (GAAP ETR) and firm value. The results show that GAAP ETR has a negative association with firm value in non-environmentally sensitive firms and a positive association with firm value in environmentally sensitive firms. Consequently, the sustainability report alters only the effect of GAAP ETR on firm value in non-environmentally sensitive firms. The results imply that, unlike environmentally sensitive firms, non-environmentally sensitive firms need sustainability reporting to reduce the reputational costs of tax avoidance.

How shareholders view tax avoidance remains unclear; research on this topic often fails to produce a uniform result. The present research fills this gap by using the existence of sustainability reporting as proof of companies’ ethical motivations to moderate the association of tax avoidance and firm value, which has not been discussed in previous research.
