Ms. Hoffman also counsels clients with custom wealth and business succession planning. This work includes federal estate and gift tax analysis and compliance, counsel with respect to fiduciary duties and related disputes, transfers and sales of closely-held business interests, estate and trust administration, and charitable gifting.

Finally, Ms. Hoffman represents clients involved in federal and state tax audits and appeals. On behalf of these clients she has negotiated settlements with the IRS and state and local taxing authorities regarding income tax, sales and use tax, estate and gift tax and property tax disputes.
