Sampling and technical audit of financial information allows you to select items within a game about which tests should be applied to obtain evidence that will enable the auditor to express an opinion on the information reviewed. This research aimed to describe the risks resulting from sampling as a technique of audit of financial information by the Public Accountants in Trujillo state, whose theoretical basis was based on Alvin and Randal (2007), Estupinan (2005), Lindegaard, Galves and Lindegaard (2000) and the International Standard on Auditing 530. Methodologically, the study was conducted following a quantitative paradigm with a design not experimental field and a descriptive typology. In conclusion, the application of sampling as a technique to obtain audit evidence generated as risks: 1) resulting from the acceptance of a test, incorrect acceptance or rejection incorrect; and 2) caused by the estimation of the procedures and controls evaluated, overestimation and underestimation; which they are an intrinsic consequence of the process of selection of samples; for this reason, the auditor should establish mechanisms to help reduce these risks to a minimum possible to thereby decrease the possibility of expressing wrong opinions.
