The Honorable John Koskinen
Com missioner of Internal Revenue
Management Report: Improvements Are Needed to Enhance the Internal Revenue
Service's Internal Control over Financial Reporting

Dear Mr. Koskinen:

On November 10, 2016, we issued our report on our audit of the Internal Revenue Service's
(IRS) fiscal years 2016 and 2015 financial statements,1 which included our opinion that IRS's
internal control over financial reporting was not effective as of September 30, 2016, because of
a continuing material weakness in internal control over unpaid assessments.2 The purpose of
this report is to present (1) a new control deficiency related to the material weakness reported in
our 2016 report and (2) other new control deficiencies that we identified during our fiscal year
2016 testing of IRS's controls, along with our recommended corrective actions related to all of
these deficiencies.3 This report also presents the status, as of September 30, 2016, of IRS's
corrective actions taken to address our recommendations detailed in our previous management
reports that remained open at the beginning of our fiscal year 2016 audit (see enc. 1).4 This
report is intended for use by IRS management.

Results in Brief

During our audit of IRS's fiscal years 2016 and 2015 financial statements, we identified a new
control deficiency involving changes to masterfile programs that contributed to IRS's continuing
material weakness in internal control over unpaid assessments as of September 30, 2016.
