The Law Offices of John P. McDonnell

Whether you need help with a tax dispute or a plan for your estate, The Law Offices of John P. McDonnell offers tax and estate counsel tailored to you. We represent individuals, families and businesses across Los Altos and the Santa Clara County area, handling federal and California tax matters alongside estate planning.

When the IRS pursues penalties or a complex fee dispute arises, we work to resolve it efficiently, often without the expense of a trial. Many of our clients come to us on referral from their CPAs and estate attorneys, because we bring focused expertise to tax and estate questions that fall outside their practice.

Our clients value a thorough, honest approach: we prepare carefully, explain where matters stand, and take on cases we believe we can win. Clients who have worked with us since the 1990s continue to bring us their business and tax matters, and we're proud of that long relationship.
