We provide new evidence about how analysts incorporate and improve on management ETR forecasts. Quarterly ETR reporting under the integral method provides mandatory point-estimate forecasts by management, but firms must record certain “discrete” tax items fully in the quarter in which they occur, polluting these forecasts. We investigate management ETR accuracy, analysts' decisions to mimic management's estimate, analysts' accuracy relative to each other or to management, and dispersion. Our comprehensive analysis reveals that analysts deviate from management more and are more accurate relative to management as complexity increases, with real effects on EPS accuracy and dispersion. In contrast to prior research that analysts ignore or are confused by taxes, we provide evidence that analysts pay attention to taxes and improve on management estimates. Based on our evidence that management's quarterly ETRs have less predictive value in the presence of discrete items, we suggest standard-setters reexamine the discrete item exception to require more disclosure.

FIN No. 48, Accounting for Uncertainty in Income Taxes (FASB 2006), requires firms to disclose tax reserves and to record changes in tax reserves at adoption of FIN No. 48 as cumulative effect adjustments in stockholders’ equity. We predict that between the enactment and adoption of FIN No. 48, relative to historical levels, firms settle disputes more often to potentially decrease visibility to the IRS and release reserves more often to reduce scrutiny and increase earnings (as opposed to retained earnings). We analyze 2005 and 2006 10-Qs and 10-Ks for the 100 largest nonfinancial, nonutility firms followed by analysts. Between enactment and adoption of FIN No. 48, relative to historical levels, firms report more settlements with tax authorities and release reserves more frequently. In addition, firms with higher IRS deficiencies are more likely to settle disputes. Between enactment and adoption of FIN No. 48, firms increased earnings by releasing $4.4 billion of tax reserves, nearly equaling the $4.5 billion released at adoption.
