Jenny Longman is Counsel in the firm's Tax Department and Trusts and Estates Department. She advises clients on numerous domestic and international tax and estate planning issues, including structures involving trusts, foundations, and usufruct and bare ownership property divisions, as well as other foreign law arrangements.

Ms. Longman advises high net worth individuals, family offices, entrepreneurs, executors, and trust companies on a variety of income tax  issues, including partnership tax, corporate reorganizations, choice of entity, business acquisitions and dispositions, cross-border withholding issues, foreign and domestic trust matters, state and local tax planning, and tax controversy matters. She has counseled clients under audit by the IRS and New York State, as well as many clients who have chosen to come into U.S. tax compliance through the Offshore Voluntary Disclosure Program, the Streamlined Filing Compliance Procedures, and other IRS programs.  She has also advised statutory executors and non-U.S. estates under audit for U.S. estate taxes.

Ms. Longman’s cross-border tax work ranges from classification of trusts as grantor or nongrantor and domestic or foreign, the application of the “throwback tax,” U.S. income taxation of foreign estates and trusts, and residency and domicile matters. She regularly advises on subpart F, passive foreign investment company and double tax treaty issues. Ms. Longman counsels nonresidents looking to move to the U. S. on pre-immigration tax planning, and similarly counsels U.S. citizens and green card holders looking to expatriate on Exit Tax matters. 

She also advises on cross-border estate planning issues, including domicile-related planning, application of estate tax treaties, and structuring complex estate plans to account for both domestic and foreign law concerns.

In the real estate area, Ms. Longman advises foreign investors on structuring U.S. real estate investments, looking to maximize U.S. income tax efficiency as well as minimize U.S. estate tax exposure.
