This study finds that banks are more likely to assist their corporate clients' tax avoidance activities when they are dual-holders (i.e., hold both debt and equity) of the client firms. Using the exogenous change in firms' bank dual holding due to bank mergers, we conduct difference-in-differences (DiD) tests to draw causal inferences. We find that firms that establish dual holding relationships with banks experience a three percent decrease in the effective tax rate than those that do not. The effect of dual holding is more pronounced when banks have larger equity or loan shares of the firm, have more expertise in tax assistance, or are specialists in the firm's industry. This effect is also stronger for client firms with more foreign income and unexploited tax-saving capacity.
