EXHIBIT 34.1

[KPMG LLP Letterhead]

Report
of Independent Registered Public Accounting Firm

The Board of Directors

Citibank, N.A.:

We have examined managements assertion,
included in the accompanying Report on Assessment of Compliance with Applicable Servicing Criteria, that Citibank, N.A. (the Company) complied with the servicing criteria set forth in Item 1122(d) of the Securities and Exchange
Commissions Regulation AB (the Servicing Criteria) for all asset-backed securities transactions conducted by the Citibank Credit Card Issuance Trust that were registered with the Securities and Exchange Commission pursuant to the
Securities Act of 1933 where the related asset-backed securities were outstanding during the year ended December 31, 2017 (the Platform), except for servicing criteria 1122(d)(1)(iii), 1122(d)(2)(iii), 1122(d)(2)(vi), 1122(d)(4)(x),
1122(d)(4)(xi), 1122(d)(4)(xii) and 1122(d)(4)(xiii), which the Company has determined are not applicable to the activities it performs with respect to the Platform, as of and for the year ended December 31, 2017. With respect to applicable
Servicing Criteria 1122(d)(1)(v), the Company has determined that there were no relevant activities performed during the year ended December 31, 2017 with respect to the Platform, because there were no occurrences of events that would require
the Company to perform such activities. Appendix A to this report identifies the individual asset-backed transactions and securities defined by management as constituting the Platform. Management is responsible for the Companys compliance with
the Servicing Criteria. Our responsibility is to express an opinion on managements assertion about the Companys compliance with the Servicing Criteria based on our examination.

Our examination was conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States) and in accordance with
attestation standards established by the American Institute of Certified Public Accountants to obtain reasonable assurance and, accordingly, included examining, on a test basis, evidence about the Companys compliance with the Servicing
Criteria and performing such other procedures as we considered necessary in the circumstances. Our examination included testing selected asset-backed transactions and securities that comprise the Platform, testing selected servicing activities
related to the Platform, and determining whether the Company processed those selected transactions and performed those selected activities in compliance with the Servicing Criteria. Furthermore, our procedures were limited to the selected
transactions and servicing activities performed by the Company during the period covered by this report. Our procedures were not designed to determine whether errors may have occurred either prior to or subsequent to our tests that may have affected
the balances or amounts calculated or reported by the Company during the period covered by this report for the selected transactions or any other transactions. We believe that our examination provides a reasonable basis for our opinion. Our
examination does not provide a legal determination on the Companys compliance with the Servicing Criteria.

In our opinion, managements
assertion that the Company complied with the aforementioned Servicing Criteria as of and for the year ended December 31, 2017, is fairly stated, in all material respects.
