Background
Fluent in the language of tax legislators and regulators. Trusted counsel to companies navigating legal implications of U.S. policy. Served under three different House Ways and Means Committee chairmen.
Harold Hancock offers technical tax advice for planning transactions and investments, and he resolves complex policy and regulatory issues by engaging key officials in Congress, the Treasury Department and the White House. As former counsel to three House Ways and Means Committee chairmen, including former Reps. Dave Camp (R-MI), Paul Ryan (R-WI) and Kevin Brady (R-TX), Harold identifies and secures vital tax credits, deductions and exemptions for domestic and international corporations.
With a deep understanding of the U.S. tax code, Harold’s value lies in his ability to develop creative and credible policy solutions that address his clients’ needs. He then distills those proposals into messaging policymakers and regulators find compelling while also leveraging his personal relationships across Washington, D.C. to reach key decision-makers. Whether Harold is advocating for a tax policy before members on the Senate Finance Committee and House Ways and Means Committee or meeting with an Internal Revenue Service regulator as guidance is being drafted, he bolsters clients’ credibility by presenting thoughtful recommendations to government officials. Harold can be found on the frontlines of fluid policy conversations representing clients that range in size and sector. He is an invaluable advocate for small businesses navigating the Paycheck Protection Program and is actively engaging tax-writers in Congress and the administration as renewable energy incentives are determined.

Representative Matters
- Secured a private letter ruling (PLR) for a leading retirement services company that clarified an international provision in the TCJA and saved the company over $400 million dollars. This required direct engagement with the Internal Revenue Service and securing support from key members of Congress.
- Represented one of the nation’s largest energy and natural gas companies facing an unexpected threat when the company was deemed ineligible to receive crucial deductions from the TCJA. Successfully devised a solution that allowed the client to be covered and recruited support from Congress, the Treasury Department, the White House and the Office of Management and Budget, ultimately saving the client hundreds of millions of dollars over the next ten years.
