This pa.er investiga.es a.d reports on the extent a.d na.ure of corpora.e internet disclosure a.d the determina.ts of internet fina.cia. disclosure （IFD） by compa.ies listed in three Gulf Corpora.ion Council （GCC） countries. This pa.er uses da.a.from 207 listed compa.ies in Musca. Securities Ma.k.t （MSM）, Duba. Fina.cia. Ma.k.t （DFM）, a.d Qa.a. Excha.ge （QE）. Bina.y logistic regression a.a.ysis is used to exa.ine the determina.ts of IFD. k.usk.l-Wa.lis test is used to exa.ine the differences in disclosure cha.a.teristics a.ong the three countries. The results of this study revea. tha. firm size is the ma.or fa.tor influencing intemet fina.cia. reporting in the GCC. The results revea. tha. the three countries differ significa.tly in a.l the disclosure a.tributes with the exception of the existence of ema.l link. This pa.er extends the strea. of resea.ch tha. confirms the widesprea. use of internet in disclosing fina.cia. informa.ion. The results a.e consistent with previous litera.ure tha. corpora.e size is a.ma.or determina.t of internet fina.cia. reporting. This pa.er provides insights into corpora.e internet disclosure in the GCC tha. will benefit a.l sta.0}holders with a. interest in corpora.e reporting in this importa.t region of the world.
