It operates as a Section 527 organization and is chaired by a Republican member of the House, currently Richard Hudson. The NRCC is governed by an Executive Committee of 11 members, including the party's House Leader.

The NRCC provides financial contributions to Republican candidates and party organizations, along with technical and research assistance. It conducts voter registration, education, and turnout programs to strengthen Republican presence in the House. The committee raises and spends significant funds on independent expenditure advertising to support Republican candidates. Its primary focus is on engaging voters and enhancing Republican turnout through various programs. The NRCC plays a vital role in supporting Republican candidates and party organizations in their electoral efforts.
