Leah provides national and state tax strategy and audit assistance for clients on a full range of tax matters, including nexus, combination and apportionment, and net operating loss issues.

She is particularly well-known for her advocacy in New York City and New York State, as well as for advising on the impact of the massive New York tax reform undertaken in 2014 and 2015. She was appointed to the New York City Department of Finance Commissioner’s Advisory Board (2014–present) as well as to the city’s Pass-Through Taxation Working Group (2014–present), a think tank formed by the Department of Finance to assist with bringing reform to the city’s Unincorporated Business Tax.

She is the author of the “In a New York Minute” column published by State Tax Notes.
Leah is also well known for her advocacy in New Jersey tax disputes, covering income tax and sales tax matters.

She has been appointed to the New Jersey Supreme Court Committee on the Tax Court (2017 to current, co-chairing the Committee in the 2019-2020 term) and authors the State Tax Notes column, “The Jersey Short—Everything You Need to Know about New Jersey Tax.”
