Earnings Management through Tax Reserves and Auditor-Provided Tax Services

This study investigates whether firms continue to use tax reserves to achieve financial reporting objectives in the post-FIN 48 period and the effect of auditor-provided tax services on earnings management through tax reserves. Three types of earnings management incentives are considered in this study: meeting or beating the consensus forecasts, income smoothing, and taking an “earnings bath.” The analyses yield evidence that only non-large firms manipulate tax reserves to meet/beat earnings forecast in the post-FIN 48 period; however, tax reserves are still utilized by both large and non-large firms to smooth earnings. Moreover, evidence is provided that the auditor who provides more tax services facilitates large firms’ earnings smoothing in the post-FIN 48 period, implying independence impairment. But this behavior does not exist within non-large firms, arguably because the auditor does not compromise independence for less important clients.
