Impact of debt and taxes on earnings persistence of Portuguese SMEs

Abstract

Purpose -We analyze how debt burden and income taxes affect the earnings quality of Portuguese SMEs, using earnings persistence as a proxy for earnings quality. More specifically, we intend to find out whether the high indebtedness of these firms causes a greater tax effect than debt effect.Theoretical framework -While credit banks represent the main source of financing for SMEs, they tend to reduce their earnings in order to avoid taxes. However, this activity can be costly for their development, given that banking institutions demand earnings persistence to reduce the risk of default, in accordance with contract theory.Design/methodology/approach -We collect data for 140 Portuguese SMEs over the period from 2015 to 2021 to run panel data regressions.Findings -Debt and earnings persistence are negatively related, so this relationship tends to degrade earnings quality, which is inconsistent with capturing bank confidence. Furthermore, debt maintains the negative effect with income taxes in the model. However, in this combination, income taxes become significant to explain the negative influence on earnings persistence, which is consistent with tax avoidance. Finally, we control for firm size, which is positively associated with earnings persistence. Overall, taking together the determinants of debt, income tax and size, Portuguese SMEs do not have persistent earnings.Practical & social implications of research -This study may be useful for several stakeholders of Portuguese SMEs, namely tax authorities, creditors, managers and academics, as it shows that debt and especially taxes have a negative impact on the earnings persistence, which signals a decrease in the quality of financial reporting.Originality/value -In the most leveraged Portuguese SMEs, debt is not a governance mechanism to control managers' decisions, as more debt reduces earnings persistence, meaning that managers are not sensitive to capturing creditors' confidence. In addition, the tax effect is more relevant than the debt effect for earnings persistence. Faced with interest rate rigidity, managers exploit the discretionary nature of tax decisions.

Firms’ Investment Level and (In)Efficiency: The Role of Accounting Information System Quality

“…Regarding the underinvestment, the lower quality the accounting information system, the lower the tendency for underinvestment. This result is the opposite to Linhares et al (2018) and Verdi (2006) and may be explained by the fact that even if financial statements give the true situation, shareholders may not invest, even with positive NPV opportunities, if the indebtedness level is high, as it would imply that most of the benefits would be captured by the creditors (Pereira et al 2023a).…”

“…In the same vein, Gaio et al (2023) and Lambert et al (2007) suggest that the increase in the quality of financial reports leads to relevant economic implications in firms, such as the efficiency of investments made. Moreover, Pereira et al (2023a) find empirical evidence that Portuguese small and medium entities (SMEs) with higher levels of investment tend to have a more conservative accounting practice to capture investors' confidence.…”
