While prior research finds that auditors with tax expertise facilitate aggressive tax planning among their clients, this conclusion is based on auditors who provide non-audit tax services. We predict that auditors who provide attestation services have incentives to reduce misstatement risk by curbing tax aggressiveness. Using Chinese data, we identify tax-expert signatory auditors as those who are Certified Tax Agents. As predicted, we find that clients of signatory auditors with tax expertise engage in less tax aggressiveness than clients of signatory auditors without tax expertise. Consistent with a causal relation, we find that an exogenous decrease in tax rates, which reduces clients’ incentives to engage in tax aggressiveness, weakens the effect of tax-expertise on tax aggressiveness. We also find that tax-expert auditors attenuate the type of tax aggressiveness that increases misstatement risk, and that the channels through which tax-expert auditors constrain tax aggressiveness include audit adjustments that increase taxable income.
