Gaetano Mortillaro

At UKG, I manage quarterly and annual U.S. international tax calculations for foreign subsidiaries, including Subpart F and GILTI, using D365 data, Excel workbooks, and OneSource compliance processes.

I've enhanced tax workbooks for accuracy and auditability, implemented FY25 tax-law changes, and rebuilt FY26 models for changes under the One Big Beautiful Bill Act. I also developed an international entity structure and compliance map and automated recurring tax analysis with configurable Excel threshold logic.

Previously at Ernst & Young and PricewaterhouseCoopers, I prepared and reviewed international tax reporting for multinational corporate, partnership, private equity, and trust structures. My work included Forms 5471, 5472, 8858, 8865, 1042-S, 1120, 1120-F, and 1065; Subpart F, GILTI, foreign tax credits, GloBE, ASC 740 provisions, transfer pricing, and cross-border transaction consulting.

My legal and tax training helps me translate Internal Revenue Code authority, regulations, treaty considerations, and technical research into practical workpapers, procedures, and compliance decisions.
