Gregory Hartker

Partner

Greg Hartker focuses his practice on domestic and international corporate and partnership tax issues. Of particular focus is planning for intangible property, both outbound and inbound, and efficient supply chain structuring. His international tax background includes matters involving Subpart F, global intangible low-taxed income (GILTI), foreign-derived intangible income (FDII), passive foreign investment companies (PFICs), foreign tax credits, withholding, treaty issues, cost sharing, and cross-border transfer pricing. He has advised on some of the largest and most complex restructurings—with values of multiple $US billions—resulting from recent changes in law.

Greg also represents clients in both taxable and tax-deferred mergers and acquisitions, public and private issuances of debt instruments, and partnership and LLC structuring and operating issues.  His work regularly involves M&A transactions valued in the multiple $US billions as well as transactions involving emerging growth and start-up companies.

Greg regularly lectures for professional and industry groups and events (including TEI, the TEI-SJSU High Tech Tax Institute, and the Pacific Rim Tax Conference, among others) on various topics relating to international tax provisions, and under Subchapters C and K.
