Nuveen Multistate Trust IV

333 West Wacker Drive

Chicago, Illinois 60606

Dear Ladies and Gentlemen:

We have acted as counsel for Nuveen Multistate Trust IV (the “Trust”), a trust duly organized and validly existing under the laws of the Commonwealth of Massachusetts, in connection with Post-Effective Amendment No. 48 to the Trust’s Registration Statement on Form N-1A (the “Registration Statement”) relating to the issuance and sale by the Trust of an indefinite number of authorized shares of beneficial interest under the Securities Act of 1933, as amended (the “1933 Act”), and under the Investment Company Act of 1940, as amended. We have examined such governmental and corporate certificates and records as we deemed necessary to render this opinion and we are familiar with the Trust’s Declaration of Trust and its By-Laws, each as amended to date.

Based upon the foregoing, we are of the opinion that the shares of beneficial interest of the Trust’s series proposed to be sold pursuant to the Registration Statement, when paid for as contemplated in the Registration Statement, will be legally and validly issued, fully paid and non-assessable, except that, as disclosed in the Registration Statement, shareholders of the Trust may, under certain circumstances, be held personally liable for its obligations. However, the Trust’s Declaration of Trust contains an express disclaimer of shareholder liability for acts or obligations of the Trust and requires that notice thereof be given in each agreement, obligation or instrument entered into or executed by the Trust or the trustees. The Trust’s Declaration of Trust further provides for indemnification out of the assets and property of the Trust for all losses and expenses of any shareholder held personally liable for the obligations of the Trust. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability is limited to circumstances in which both inadequate insurance existed and the Trust or a series thereof was unable to meet its obligations. We hereby consent to the filing of this opinion as an exhibit to the Registration Statement, to be filed with the Securities and Exchange Commission, and to the use of our name in the Trust’s Registration Statement to be dated on or about September 28, 2026 and in any revised or amended versions thereof. In giving such consent, however, we do not admit that we are within the category of persons whose consent is required by Section 7 of the 1933 Act and the rules and regulations thereunder.

Very truly yours,

/s/ Dechert LLP
