Current accounting rules for segment-level reporting afford managers significant discretion in what line items to report. We predict and find firms with higher proprietary costs of disclosure (i.e., higher tax avoidance) are less likely to disclose segment-level tax information. These results are stronger for firms that define business segments on a geographic basis, where disclosure could reveal tax expense information about specific tax jurisdictions, consistent with the proprietary cost hypothesis. Overall, our results suggest some managers potentially use discretion in current guidance to avoid segment-level disclosure of taxes when these disclosures have the potential to be detrimental to the firm.10aAccounting1 aDeng, Junfang1 aSteele, Logan1 aLynch, Dan1 aGaertner, Fabio, B  uhttps://doi.org/10.2308/JATA-19-002
